Description

The invention relates to a method for producing an electrically actuatable magnetic circuit component, in particular a solenoid valve, wherein the magnetic circuit component has a pole core, a magnet armature which can be displaced with respect to the pole core and a spring arrangement that acts at least on the magnet armature, and the spring arrangement has at least one spring washer the spring washer several spring tongues in operative connection with the magnet armature and / or the pole core are formed, and the spring characteristic of the spring washer is set by deforming or at least partially separating the spring tongues during the manufacture of the magnetic circuit component. The invention also relates to an electrically actuatable magnetic circuit component.

State of the art

Methods of the type mentioned at the beginning are known from the prior art. The magnetic circuit components to be produced, for example electromagnets based on the flat armature principle, but in particular magnetic valves, have the pole core and the magnet armature. The so-called working air gap is located between the pole core and the magnet armature. When the magnetic circuit component is actuated, the magnet armature is displaced in relation to the pole core, which changes the size of the working air gap. Usually, the pole core and the magnet armature are arranged with respect to one another in such a way that an end face of the pole core lies opposite an end face of the magnet armature. The two end faces are preferably parallel to one another. The spring arrangement is provided to reset the magnet armature as soon as the magnetic circuit component is no longer actuated. For this purpose it acts at least on the magnet armature, but preferably both on the pole core and on the magnet armature. For the latter embodiment, the spring arrangement is arranged at least in some areas between the pole core and the magnet armature. The smaller the working air gap, the greater the magnetic force exerted on the armature via the pole core. Usually, there is a non-linear, in particular exponential, increase in the magnetic force as the axial working air gap becomes smaller.

Such a magnetic force curve (which denotes the magnetic force over the size of the working air gap) makes it difficult to position the magnetic circuit component precisely. In the case of solenoid valves in particular, it is desirable to achieve constant adjustability or proportionalization. Only in this case can the current corresponding to a specific pressure difference be fed to the solenoid valve via a valve seat of the solenoid valve. In order to achieve better adjustability, the spring arrangement usually has at least the spring washer. This can be connected in parallel to a compression spring which urges the magnet armature into a closed position of the magnet valve. The compression spring, in particular a helical compression spring, preferably has a linear spring characteristic (which describes the spring force over the spring travel). The spring washer is preferably chosen with a slightly progressive spring characteristic. Together with the linear spring characteristics of the helical compression spring, the slightly progressive spring characteristic results in a progressive spring characteristic which counteracts the likewise progressive magnetic force curve. This considerably improves the adjustability of the solenoid valve or the magnetic circuit component. The spring washer is inserted, for example, in the working air gap between the pole core and the magnet armature. The end faces or pole faces of the pole core and magnet armature can be designed specifically in order to produce the desired spring characteristics of the spring washer. In the manufacture of the magnetic circuit component, however, the difficulty arises that a calibration or setting of the individual components of the magnetic circuit component, in particular the spring characteristics of the spring arrangement or the spring washer, is necessary to achieve a certain setting accuracy. So far, a complex manufacturing process has been carried out in order to set a specific spring characteristic of the spring washer, for example by means of fine cutting, etching, laser cutting and / or eroding.

Specifically describes the generic publication WO 95/31 241 A1 a control valve for controlling a liquid, for example a gas flow such as air, in particular for use in an anesthesia machine. The control valve consists of a valve housing and a controller housing. The valve housing has an inlet for the flow which leads to a valve seat and a valve chamber, and an outlet for the flow which is connected to the valve chamber. In addition, there is a valve element that cooperates with the valve seat to regulate the flow of gas through the valve housing. A permanent magnet and a yoke arrangement form an annular air gap that contains a radial magnetic field. A tubular bobbin with a coil on it is movable in this magnetic field.

Disclosure of the invention

In contrast, the method with the features of claim 1 has the advantage that the magnetic circuit component can be manufactured more easily and more cost-effectively, this being true in particular for the spring washer. this will achieved according to the invention by the multiple spring tongues being deformed or separated differently. In principle, it is provided that during the manufacture of the magnetic circuit component, the spring characteristics of the spring washer are set by deforming or at least regionally severing the spring tongues. The calibration of the magnetic circuit component or its components thus takes place after the individual components have been produced. By calibrating the magnetic circuit component or the spring washer, it is possible to use a more cost-effective manufacturing method such as punching for the latter. It is thus possible to produce a large number of magnetic circuit components each with the same or at least very similar, reproducible spring characteristics of the spring washer.

The spring tongues can be formed by separating or deforming the spring washer. The division is provided, for example, by introducing slots in the radial direction, so that the spring tongues are present in the radial direction. When the magnetic circuit component is manufactured, the spring characteristics of the spring washer are then adjusted to the desired spring characteristics by deforming or cutting off the spring tongue. In this case, for example, the entire spring washer can also be deformed at least locally in order to achieve this. The spring tongue is to be understood as a cross section through the spring washer, which is deformed according to the desired spring characteristic. Magnetic circuit components or solenoid valves produced in the manner described above can be used, for example, as normally closed solenoid valves, in particular in ABS, TCS or ESP systems. With the method proposed here, the spring characteristics of the spring washer can be set as desired subsequently, that is, after the spring washer has been produced. The spring washer can be present as an individual part or it can already be part of the spring arrangement. In the latter case, the spring characteristics of the entire spring arrangement can be adjusted during the manufacture of the magnetic circuit component or during the calibration.

A further development of the invention provides that the spring tongues are formed mainly in the radial direction or with a component in the circumferential direction. The spring tongues accordingly run essentially radially with respect to a longitudinal axis of the spring washer. This longitudinal axis corresponds to the direction in which the spring washer in the magnetic circuit component is acted upon by the pole core and / or the magnet armature. The spring tongues are therefore essentially perpendicular to this direction of force action. The spring tongues can run exclusively in the radial direction or the course can also have a component in the circumferential direction. In the latter case, the spring washer can have a saw blade-like design.

A further development of the invention provides that there is at least one support area for the magnet armature or the pole core on the spring tongues. The support area is provided for establishing the operative connection between the spring tongues and the magnet armature or the pole core. The spring tongues come into physical contact, for example, with the end face of the magnet armature or the pole core.

A further development of the invention provides that the spring tongues are arranged starting from a base element of the spring washer on the outer or on the inner edge of the spring washer. The base element is preferably designed in a ring shape. The spring tongues start from the base element and extend from this either outwards or inwards, preferably in a radial direction.

A further development of the invention provides that the deformation takes place by adjusting the spring tongues in the axial direction upwards or downwards. As already stated above, the axial direction is the direction in which the spring washer is acted upon by force from the magnet armature or the pole core. By deforming or adjusting the spring tongues in one of the specified directions, the spring tongues come into operative connection with the magnet armature or the pole core in each case with different axial positions of the magnet armature or each have a different spring characteristic. The spring tongues are subjected to an after-treatment in order to set the desired spring effect or spring characteristic. The desired spring characteristic can include a complete characteristic curve of the spring force over the spring travel or just individual points of the characteristic curve. By adjusting the spring tongues, for example, a pretension which the spring washer exerts on the pole core in its rest position can be set in a targeted manner.

A further development of the invention provides that the spring tongues are formed by producing at least two slots in the spring washer. The slots can have any width and preferably run in the radial direction, starting from the base element of the spring washer. For each of the spring tongues, the deformation or separation can now be carried out in order to set the spring characteristics.

A further development of the invention provides that the spring tongues are distributed evenly over the circumference of the spring washer. In particular, the distribution of the spring tongues should be symmetrical with respect to a center point of the spring washer. In this way, the fatigue strength of the magnetic circuit component can be increased because the spring force caused by the spring washer is essentially evenly distributed.

The invention provides that the spring tongues are deformed or separated in different ways. It is therefore not necessary for all of the spring tongues to be deformed or adjusted in the same direction. Rather, it can be provided that several spring tongues are adjusted in different directions or that at least one spring tongue is deformed and at least one other spring tongue is severed.

A further development of the invention provides that the setting of the spring characteristic is carried out before assembly or during pre-assembly of the magnetic circuit component. In principle, the spring characteristics can be set at any time. It is possible to perform the spring characteristics of the spring washer before it is installed in the magnetic circuit component, that is, before it is assembled. Alternatively, it is also possible to carry out the setting during the pre-assembly of the magnetic circuit component. In this case, interactions between the spring washer and the other components of the magnetic circuit component can be taken into account, and a final calibration of the magnetic circuit component or the solenoid valve can already be carried out. In this way, after the spring characteristics of the spring washer have been set, the magnetic circuit component is already essentially present with its final properties, in particular adjusting properties. The setting can take place in such a way that the spring washer is first installed in the magnetic circuit component and a measurement is carried out on the magnetic circuit component, in particular this being electrically actuated. The spring washer is then removed from the magnetic circuit component again and the spring characteristics of the spring washer are set by deforming or separating on the basis of the measurement results obtained. This procedure, consisting of installing, measuring, removing and adjusting, can in principle be carried out as often as desired in an iterative process until the desired accuracy is achieved in order to calibrate the magnetic circuit component or the spring washer.

The invention further relates to an electrically actuatable magnetic circuit component, in particular a solenoid valve, preferably manufactured according to the method described above, with a pole core, a magnet armature displaceable with respect to the pole core and a spring arrangement acting at least on the magnet armature, the spring arrangement having at least one spring washer, wherein Several spring tongues in operative connection with the magnet armature and / or the pole core are formed on the spring washer by making at least two slots in the spring washer, and the spring characteristic of the spring washer is set by deforming or at least partially separating the spring tongues. It is provided that a plurality of spring tongues that are operatively connected to the magnet armature and / or the pole core are formed on the spring washer, and the spring characteristics of the spring washer are set by deforming or at least partially separating the spring tongues. It is also provided that the plurality of spring tongues are deformed or separated differently. The magnetic circuit component can be developed in accordance with the above statements. In order to set the spring characteristics of the spring washer, the spring tongues can, as already explained above, be deformed or separated. Provision can also be made for the entire spring washer to be deformed at least in some areas, the spring tongues in this case being viewed as a cross section through the spring washer. For example, the spring washer is deformed in a support area in which it rests against the magnet armature or the pole core. This support area is often provided on one of the edges of the spring washer, so that this disk edge would have to be bent open plastically. However, this requires very high forces. Furthermore, the very deformation-resistant spring washer is highly stressed by such an imposed deformation. Such a configuration can, however, result in advantages compared to a spring washer with spring tongues separated by slots. For example, a relative rotation of the spring washer with respect to the magnet armature or the pole core is possible without problems. In this case, individual spring tongues separated by slots cannot get caught.

The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing, without the invention being restricted. Show it:

The 1 shows a cross section through a magnetic circuit component 1 , which in the present case as a solenoid valve 2 is trained. The solenoid valve 2 has a pole core 3 , a magnet armature 4th and a spring assembly 5 on. The spring arrangement 5 consists in the embodiment of the solenoid valve shown here 2 from a compression spring 6th , which is present as a helical compression spring, and a spring washer 7th . The spring washer 7th is between the pole core 3 and the magnet armature 4th in the so-called working air gap 8th arranged. The working air gap 8th lies between one end face 9 of the pole core 3 and an end face 10 of the armature 4th in front. The spring washer 7th is essentially annular. On its inside, it has a first support area 11 on, which with an end face area 12 the front 9 of the pole core 3 is in touch or rests on it. The spring washer faces radially on the outside 7th a second support area 13 on, which with an end face area 14th the front 10 of the armature 4th is in touch or rests on it. The spring washer is located in the armature arrangement shown here 4th to Polkern 3 so both on the armature 4th as well as on the pole core 3 at. In doing so, it creates a spring force that sets the magnet armature 4th from the pole core 3 pushes away.

In a central recess 15th of the armature 4th is the compression spring 6th arranged. This is either on the bottom of the recess 15th or, as shown here, on a locking piece 16 on. The locking piece 16 is in the recess 15th attached. On the the breech block 16 the side facing away is the compression spring 6th on a pressure piece 17th at. This is in the recess 15th axially movable and occurs with its the compression spring 6th facing away from the pole core 3 opposite or is on its front side 9 at. Just like the spring washer 7th thus also causes the compression spring 6th a spring force which the magnet armature 4th from the pole core 3 pushes away. The spring arrangement 5 in which the compression spring 6th and the spring washer 7th are connected in parallel as explained above, the solenoid valve is therefore urging 2 or a sealing element 18th , which with the magnet armature 4th is operatively connected, in a closed position of the solenoid valve 2 . In this closed position, no fluid can pass through an inflow opening 19th and a valve seat 20th through into a fluid chamber 21st and then through at least one outlet opening 22nd from this flow out, while that is possible in an at least partially open position.

By pressing the solenoid valve 2 with electrical current, i.e. an electrical actuation, is via the pole core 3 a magnetic force causes the armature 4th from the closed position of the solenoid valve 2 out towards the open position on the pole core 3 moved towards. The spring force of the spring arrangement acts here 5 against this magnetic force. The further the magnet armature 4th on the pole core 3 is moved, so the smaller the working air gap 8th however, the more the magnetic force increases. In particular, there is an exponential behavior of the magnetic force over the size of the working air gap 8th in front. The one through the solenoid valve 2 The current flowing therefore does not correspond directly to the desired pressure difference across the valve seat 20th or the solenoid valve 2 . This complicates the constant adjustability or proportionalization of the solenoid valve 2 . Because of this, the spring washer 7th the compression spring 6th connected in parallel.

Manufacturing fluctuations in the components of the solenoid valve 2 make to achieve the necessary functional accuracy of the solenoid valve 2 however, calibration or adjustment of the components is required. This is especially true for the compression spring 6th and the spring washer 7th for which a certain desired spring characteristic is to be achieved. The following will focus on the calibration or setting of the spring characteristics of the spring washer 7th To be received. The presented procedure makes it possible to use the spring washer 7th in cost-effective manufacturing processes such as punching, instead of using complex and expensive processes such as fine blanking, etching, laser cutting and / or eroding. By then setting the spring characteristics of the spring washer 7th any differences that may be caused thereby are eliminated so that a comparatively low series spread is achieved.

The 2a shows a portion of a first embodiment of the spring washer 7th . This has a basic element 23 and proceeding from this in spring tongues extending in the radial direction 24 on. In the basic element 23 is a recess 25th provided, which after assembly of the solenoid valve 2 from the pressure piece 17th is penetrated. In the 2a is also indicated that the first support area 11 in an inner area of the spring washer 7th is located, whereas the second support area 13 on the spring tongues 24 radially outside on the spring washer 7th is provided. The spring tongues 24 are made of slots 26th separated so that the spring tongues 24 are essentially independently deflectable. In the embodiment of the spring washer shown here 7th are the spring tongues 24 on the outer edge of the spring washer 7th arranged, so point starting from the basic element 23 in the radial direction outwards. Alternatively, it is of course also possible to use the spring tongues 24 to be arranged on the inner edge so that they are from the basic element 23 starting out pointing inwards. Such a design has advantages in terms of handling because there is a risk of entanglement when assembling the solenoid valve 2 is decreased.

The 2 B shows a section of a variant of the first embodiment of the spring washer in a plan view. While the spring tongues 24 the Indian 2a spring washer shown 7th have an essentially radial course, that is to say extend outward in the radial direction, the course of the spring tongues has 24 the Indian 2 shown variant on a peripheral component. The slots run for this purpose 26th between the spring tongues 24 preferably curved or arched. The spring washer 7th to this extent has a saw blade-like structure. It can be provided that the width of the slots 26th remains constant over its respective course or alternatively varies. Accordingly, a width of the spring tongues that changes over their course can also 24 be realized.

The 3 shows a second embodiment of the spring washer 7th . This is basically structured in a similar way to that in 2a Embodiment shown, so that in this respect reference is made to the preceding statements. However, the slots are 26th Very narrow, so that only a cutting free of the spring tongues 24 present. The dimensions of the slots 26th in the circumferential direction of the spring washer 7th are such that the spring tongues 24 possibly still be able to touch. The slots 26th are therefore designed as free cuts. At the bottom of every slit 26th is a hole 27 provided which pivoting the spring tongues 24 allows against each other without it getting caught or jammed between them. In principle, the spring tongues 24 and the slots 26th for the embodiments of the spring washer described above 7th be freely distributed over the circumference. However, a uniform arrangement of the spring tongues is advantageous 24 or the slots 26th .

The 4th shows a section of the solenoid valve 2 with an area of the pole core and an area of the magnet armature and the spring washer 7th . It becomes clear that at least one of the spring tongues 24 in the axial direction (based on a longitudinal axis 28 of the solenoid valve 2 or the spring washer 7th ) is employed upwards. This at least one hired spring tongue 24 is hereinafter referred to as the spring tongue 29 designated. In the embodiment of the solenoid valve shown here 2 are at least two of these employed spring tongues 29 intended. From the 4th it becomes clear that the second support area 13 not just on the spring tongues 24 , but also on the spring tongues 29 extends. The spring tongues too 29 so can with the magnet armature 4th come into physical contact. This is the case when the magnet armature 4th and the pole core 3 have approached each other sufficiently far. By adjusting the spring tongues 29 upwards or against the pole core 3 and away from the magnet armature 4th , becomes the spring characteristic of the spring washer 7th or the spring force exerted by this by not using the material of the spring washer 7th decreased. At a distance between the magnet armature 4th from the pole core 3 such that the spring tongues 29 not yet with the magnet armature 4th come into physical contact, causes the spring washer 7th a first spring force. If during the opening of the solenoid valve 2 , so a meeting of magnet armatures 4th and pole core 3 , also the spring tongues 29 in physical contact with the armature 4th step, causes the spring washer 7th a greater spring force. The spring characteristic, i.e. that of the spring washer 7th Spring force caused by the spring travel, can thus be achieved by deforming the spring tongues 24 can be set as required. It can also be provided that the spring tongue 29 to employ different degrees. In this way, a multiple kinking or discontinuous spring characteristic of the spring washer can be achieved 7th be achieved. When deforming the spring tongues 24 or spring tongues 29 Care must be taken that there are no (protruding) burrs or an impermissibly large deformation of the basic element 23 occurs in order to have an impermissible influence on the magnetic circuit or the movement of the solenoid valve 2 to avoid.

The 5 shows a second embodiment of the based on 4th described solenoid valve 2 . In this respect, reference is made to the statements above. The difference to the embodiment of 4th lies in the fact that the spring tongues 29 are employed downwards. This means that when the solenoid valve opens 2 , i.e. moving the armature towards one another 4th and the pole core 3 , earlier with the magnet armature 4th come into physical contact than the non-engaged or deformed spring tongues 24 . This results in such an embodiment of the solenoid valve 2 the possibility of a mechanical spring preload of greater than 0 N with a stroke of the solenoid valve 2 or a deflection of the armature 4th from zero. The further course of the spring characteristic or the spring characteristic is then depending on the design of the spring washer 7th stiffer or flatter.

In general, the spring tongues described above 24 or slots 26th for realizing an anti-rotation lock for the spring washer 7th or to recognize the correct angle of the spring washer assembly 7th can be used. This can have advantages in terms of the quality of the solenoid valve 2 (with regard to control quality, scatter, and the like) or during assembly. For example, different dimensions of the slots 26th or lengths of the spring tongues 24 respectively 29 be used.

Instead of the slots 26th in the spring washer 7th bring in and thus the spring tongues 24 respectively 29 To be separated mechanically from one another, the invention cannot provide, no slots 26th in the spring washer 7th bring in. In this case, the spring tongues 24 for example by corrugations of the spring washer 27 are shown in the circumferential direction. Alternatively, a cross section through the spring washer can also be used 7th as a spring tongue 24 be considered. In this case, the spring characteristics are set by deforming the entire spring washer 7th . It is particularly provided that the spring washer 7th in the first support area 11 and / or the second support area 13 to deform and make up or down.

The 6th shows a third embodiment of the spring washer 7th . This is essentially in accordance with the first embodiment, which is based on the 2a has been described. The difference is that the spring characteristics of the spring washer 7th not by deforming or adjusting the spring tongues 24 is made, but by at least partially separating the spring tongues 24 . The separation of the spring tongues 24 takes place in such a way that it is no longer the first contact area 11 or the second support area 13 have, so not with the pole core 3 or the magnet armature 4th come into physical contact. Thus, they cannot cause the spring force of the spring washer 7th contribute. The spring tongues separated at least in areas 24 are here again as spring tongues 29 designated.

The 7th shows a fourth and a fifth embodiment of the spring washer 7th . On the left of the 7th is the slot 26th shown with a large width compared to the other embodiments. This embodiment of the slot 26th can for example by punching out a certain angular range of the spring washer 7th be realized. The already known spring tongues are in turn due to the punching out of the angular area 24 in front. The right side of the 7th shows the fifth embodiment of the spring washer 7th which is similar to the one based on the 3 described embodiment is. The difference arises from the fact that the spring characteristics of the spring washer 7th not by deforming, but by cutting off the spring tongues at least in certain areas 24 is set. For those based on the 7th described embodiments of the spring washer 7th the statements apply to the 6th corresponding.

Solenoid valves 2 of the type mentioned above can be used, for example, for ABS, TCS and / or ESP systems. The spring washer 7th or the spring arrangement 5 can also be used for magnetic circuit components 1 in general, for example for electric lifting magnets (close to flat armature geometry). The solenoid valves 2 are particularly suitable for systems with increased demands on the brake pressure control quality, for example for brake systems for blending functions, in particular for vehicles with hybrid or electric drives.
