Description
Technical Field
The invention relates to the technical field of automobile manufacturing, in particular to a belt pulley transmission device, a 48V power-assisted recovery system and an air conditioning system.
Background
In 48V helping hand recovery system, mainly include: 48V helping hand retrieves motor (BRM), belt pulley, and BRM mainly plays the function through the belt drive of its front end, and its function mainly includes: starting and stopping, advanced starting and stopping, brake recovery, coasting and the like. The traditional automobile with a 48V power-assisted recovery system (BRM is integrated with an engine through a belt pulley) can save oil by 3-4% in the process of starting and stopping.
Because the same belt is lapped among the engine, the air-conditioning compressor, the belt pulley and the BRM in the automobile, when the engine works, the engine transmits driving force to the air-conditioning compressor through the wheel transmission device and the belt in sequence, so that the air-conditioning compressor is driven to work. However, in the process of stopping the engine, the belt pulley and the air conditioner compressor cannot work due to the loss of power, and if the waiting time for starting and stopping the engine is long, the air conditioner compressor cannot refrigerate or heat, so that the customer experience is seriously influenced. Therefore, part of customers can choose to close the 48V power-assisted recovery system to keep the air conditioner compressor working, and the oil consumption is increased virtually.
In view of the above problems, there are currently two solutions:
1. through providing the electronic compressor mode, the engine opens and stops the in-process promptly, and air condition compressor can obtain electric drive from power battery system, and no longer uses and passes through belt transmission drive air condition compressor by engine drive wheel transmission to guarantee opening the refrigeration performance of stopping in-process cavity pressure regulating compressor, guarantee customer's travelling comfort. However, the electronic compressor is essentially an air conditioner compressor with a set of motor and motor controller, and the cost is high. The current cost performance is not accepted by the market.
2. The gear train layout is changed, an idler wheel integrating a clutch is added, the clutch function of the idler wheel is also similar to that of the air conditioner compressor and the water pump, and the clutches and the belt pulley are integrated into a whole and used for controlling the on-off of the air conditioner compressor or the water pump, and the clutches are usually of a normally-open type. In most designs employing this arrangement, the idler divides the entire gear train into 3 layers, which are connected to the pulley of the crankshaft, the air conditioner idler and the motor idler, respectively. A clutch is designed in the idler wheel to separate or combine the idler wheel part connected with the crankshaft with the other two layers. During the design idea, in the starting and stopping process, the engine is flamed out, the clutch is disconnected, and the BRM drives the air-conditioning compressor through belt transmission. The design can guarantee that the hollow pressure regulating compressor keeps working in the starting and stopping process theoretically, and meanwhile, the economical efficiency and the comfort of driving of customers are guaranteed. However, the arrangement divides the whole wheel train into 3 layers, which increases the complexity of the wheel train, increases the requirement of axial space of the accessory system, and also needs to add additional tension wheels and other components. Ideally, a single tensioning system would be required for each tier of the train, and the two pulley system would require two-way tensioners, each at a cost of about 200rmb, because of the change in torque direction of the motor and crankshaft pulley. This design is therefore not very practical.
Aiming at the problem that the air conditioner compressor cannot work after the engine is stopped, so that the customer experience effect is poor, the technical personnel in the field are always searching for a method for solving the problem.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and embodiments, and the 48V assist recovery system and air conditioning system will be described in detail below. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Example one
Referring to fig. 1 and 2, fig. 1 is a schematic cross-sectional view of a pulley transmission device according to the present invention; fig. 2 is an exploded schematic view of a pulley drive. As shown in fig. 1, the pulley transmission comprises: the transmission mechanism comprises a first transmission component 1, a second transmission component 2 and a clutch 3 arranged between the first transmission component 1 and the second transmission component 2; when the clutch 3 is combined, the first transmission component 1 and the second transmission component 2 are in a combined state, and the motion states of the first transmission component 1 and the second transmission component 2 are the same; when the clutch 3 is disengaged, the first transmission component 1 and the second transmission component 2 are in a disengaged state, the motion state of the first transmission component 1 is unrelated to the motion state of the second transmission component 2, the motion states of the first transmission component 1 and the second transmission component 2 are not influenced mutually, and the two motion states are the same or different.
As shown in fig. 2, the clutch 3 in this embodiment is an electromagnetic clutch, and specifically mainly includes: the electromagnetic coil 30, spring 31, pressure plate 32, friction part 33 and cover 34 distributed in sequence in the space, wherein, one end of the said spring 31 is fixed with the said pressure plate 32, another end of the said spring 31 is in the free state; the friction member 33 includes a first friction plate 331 and a second friction plate 332 which are stacked and arranged to cross each other; the electromagnetic coil 30 is embedded in the second transmission part 2; as shown in fig. 3, the first friction plate 331 is fixedly connected to the first transmission member 1; the second friction plate 332 is fixedly connected to the second transmission part 2. Wherein, the spring 31 is preferably a belleville spring; the cover plate 34 is used for facilitating the assembly of the clutch 3 and the second transmission component 2; the electromagnetic coil 30 is used for providing a power source for the clutch 3, and the electromagnetic coil 30 is actually fixed on a shell of the engine through a fixed support, is not in direct contact with the second transmission part 2, and does not rotate along with the second transmission part 2, so that the use of a slip ring design is avoided, an excitation system is simplified, and the reliability of the system is improved.
In this embodiment, the clutch 3 mainly employs multi-plate friction plates (including the first friction plate 331 and the second friction plate 332), which has the advantages that a large torque can be transmitted in a limited space, and the number of friction plates can be increased or decreased according to different requirements, so as to meet the requirements of a belt transmission device. Meanwhile, no sliding friction exists between the first friction plate 331 and the second friction plate 332, so that additional cooling and lubrication are not needed, and the service life of the clutch is further prolonged.
The structure of the clutch 3 will be understood in conjunction with its two operating states, in particular as follows.
1) When the clutch 3 is in the engaged state: when the electromagnetic coil 30 is not energized (de-energized), the spring 31 is compressed to push the pressure plate 32 to act on the friction member 33, the first friction plate 331 and the second friction plate 332 which are mutually crossed and stacked are in contact, and under the action of friction force between the first friction plate 331 and the second friction plate 332, the first transmission member 1 and the second transmission member 2 are connected (i.e. in a combined state), and at the moment, the first transmission member 1 and the second transmission member 2 form a whole, so that the motion states of the two transmission members are kept consistent. When the clutch 3 is in the combined state, the electromagnetic coil 30 is not electrified, so that the clutch 3 does not generate electromagnetic loss, and the energy consumption is saved.
2) When the clutch 3 is in a disengaged state, the electromagnetic coil 30 is energized to generate an electromagnetic field, the spring 31 is attracted under the action of the magnetic force, the pressure plate 32 is close to the electromagnetic coil 30, so that the pressure plate 32 compresses the spring 31, at the moment, the first friction plate 331 and the second friction plate 332 which are mutually crossed and distributed in a stacked mode are separated, and further the first transmission part 1 and the second transmission part 2 are separated.
Further, the belt pulley transmission device also comprises a screw 5, and when the belt pulley transmission device is assembled with an engine, the first transmission component 1 is fixed on a crankshaft of the engine through the screw 5. Therefore, the rotational state of the engine coincides with the first transmission member 1.
With reference to fig. 2, when the clutch 3 of the pulley transmission is in the engaged state, the engine, the first transmission member 1 and the second transmission member 2 rotate synchronously, the power source is the engine, and the torque transmission sequence on the crankshaft of the engine is as follows: the first transmission part 1> the first friction plate 331> the second friction plate 332> the second transmission part 2> a belt, and then is transmitted to other accessories (such as an air conditioner compressor).
When the clutch 3 of the pulley transmission is in a disengaged state, the engine is in accordance with the rotational state of the first transmission member 1, and the motion state of the second transmission member 2 is not affected by the motion state of the first transmission member 1.
In order to avoid mutual interference between the first transmission component 1 and the second transmission component 2, a bearing 4 is further arranged between the first transmission component 1 and the second transmission component 2, and the bearing mainly plays a role in supporting, so that the second transmission component 2 and the first transmission component 1 can stably move relatively. Since the bearing 4 is a general mechanical structure in the art, the specific application and principle thereof will not be described herein.
Example two
The difference between the second embodiment and the first embodiment is that the specific structure of the clutch 3 of the pulley transmission device in the present embodiment is different, and the clutch 3 in the first embodiment is an electromagnetic clutch, while the clutch in the second embodiment is a jaw electromagnetic clutch, which can also transmit a larger torque in a smaller space. In order to meet the requirements that when the clutch is a jaw electromagnetic clutch, the first transmission component 1 and the second transmission component 2 are separated and combined, and the first transmission component 1 and the second transmission component 2 are correspondingly structurally improved, namely, the first transmission component 1 comprises a first connecting component 10, and the second transmission component 2 comprises a second connecting component 20.
Referring to fig. 4 and fig. 6, the clutch of the present embodiment mainly includes: the electromagnetic coil 30 ', the spring 31 ', the engaging part 33 ' and the cover plate 34 ' are distributed in sequence in the space, wherein the cover plate 34 ' is connected with the second transmission part 2; one end of the spring 31 ' is fixed to the engagement member 33 ', and the other end of the spring 31 ' is in a free state; as shown in fig. 6, the engagement part 33 ' includes a first toothed edge 331 ' to be matched with the first connection part 10 and a second toothed edge 332 ' to be matched with the second connection part 20.
The operation principle of the jaw type electromagnetic clutch is that the first transmission member 1 and the second transmission member 2 are coupled or separated by the first toothed edge 331 ' of the engagement member 33 ' and the first connection member 10, and the second toothed edge 332 ' and the second connection member 20 engaging with or disengaging from each other. Specifically, referring to fig. 4, when the electromagnetic coil 30 ' is de-energized, the spring 31 ' is compressed to push the engaging member 33 ' into between the first transmission member 1 and the second transmission member 2, so that the first toothed edge 331 ' is engaged with the first connecting member 10, the second toothed edge 332 ' is engaged with the second connecting member 20, and the clutch is in an engaged state. Referring to fig. 5, when the electromagnetic coil 30 ' is energized, a magnetic force is generated to attract the spring 31, the engaging member 33 ' approaches the electromagnetic coil 30 ', the first toothed edge 331 ' is separated from the first connecting member 10, the second toothed edge 332 ' is engaged with the second connecting member 20, and the clutch is in a separated state.

The air conditioning system comprises the 48V power-assisted recovery system and an air conditioning compressor in the third embodiment, and a belt in the 48V power-assisted recovery system is wound on the air conditioning compressor. The clutch in the belt transmission device is in a separation state in the stopping process of the engine mainly by changing the structure of the belt transmission device in the 48V power-assisted recovery system, so that the first transmission part is independent of the motion state of the second transmission part (equivalent to the decoupling of the second transmission part and a crankshaft of the engine), and as the engine only determines the motion state of the first transmission part, the engine, the second transmission part and the air-conditioning compressor in the 48V power-assisted recovery system share the same belt, when the engine is stopped, the engine is independent of the working states of the second transmission part and the air-conditioning compressor, and at the moment, the 48V power-assisted recovery motor is utilized to drive the air-conditioning compressor through the belt transmission effect, therefore, a vehicle loaded with the air-conditioning system can continuously provide air-conditioning in the starting and stopping process of the engine, and the comfort is improved, and the use of an electronic air conditioner or the design of a large-range adjusting wheel train is effectively avoided, and the system integration design cost is reduced.

In practical application, the first transmission part is fixedly connected with a crankshaft of an engine, and a belt is wound on the second transmission part and the 48V power-assisted recovery motor.
