Description
Technical field
The present invention relates to the wheel technical field.
Background technology
The so-called object that is impacted by impulsive force refers to: it is uneven or when running into obstacle that the bicycle in the enforcement, motor bike, automobile, rolling stock run into road surface (or track, as follows); During takeoff and landing; Object is collided or when landing, or the like, in these cases, object all can be subjected to the impact of impulsive force, produces deletrious vibrations and destruction.
This paper is research object with the wheel of vehicle.The various existing wheel of various vehicles all is the rigid construction body, uses this wheel, and vehicle is subjected to the impact from road shocks power strong incessantly under steam or weakly.This be because, the wheel bearing load acts on the road surface, road surface reaction acts on wheel, has set up the equilibrium of forces system, vehicle is as travelling on flat road surface, wheel road closed contact, this equilibrium of forces system is not damaged.But when Uneven road or when meeting roadblock, wheel road contact point (actual is face and the contacting of face, as follows) equilibrium of forces system is damaged, from the ground-surface impulsive force, act on wheel by wheel road contact point, make the wheel road produce the moment disengaging, impulsive force transmits rapidly on wheel and comes.The transmission excellence conductor that existing rigid body wheel is a power, impulsive force reaches and the allo wheel shaft of wheel through wheel, is reached on the vehicle damping spring (or shock absorption device of other form) by wheel shaft again.Spring is compressed under impact force action, stores impulsive force energy (about the transforming relationship between power and the energy, the back is chatted again), and the car body that is supported on the damping spring is cushioned, and avoids impulsive force moment and impacts with all strength.But, damping spring relatively herein, be supported on the car body on the spring, no matter its weight is multiple, this end that spring supports car body is a free end, and the bottom of spring is a fixed end, thereby the energy of the spring inner accumulated that has been compressed, can only on car body, discharge, cause that car body constantly rocks, upthrow sinks, jolt and can't bear, when serious, body construction suffers breakage.
Impulsive force is extremely harmful to the impact of car body, says toward light place, not only becomes flexible each bilge construction of vehicle, influences its service life, and goods is impaired, is collided, and is extruded, and influences that goods is complete to be sent to; Or making the passenger that rides endure the hardship of jolting to the fullest extent, journey is very easily tired, goes to bits.What is more, when impulsive force is big, causes the vehicle breakage, causes the traffic safety accident, and this is the common phenomenon that arrives in the communications and transportation.
Therefore, eliminate the deleterious effect of impulsive force,, improve transportation service level, have reality and positive meaning guaranteeing traffic safety to operational vehicle.
Summary of the invention
The purpose of damping wheel that the present invention develops is: eliminate the deleterious effect of impulsive force to vehicle, prevent vibrations, avoid destroying, improve the transportation service quality, guarantee traffic safety.
For achieving the above object, the technical scheme of damping wheel of the present invention is: it is by the rim piece, the round and elastic structure that bearing and round screw thread compression spring are formed, described rim piece has even number, these rim pieces are sleeved on the spring radius stay of the bearing that wherein is provided with wheel shaft by the spring radius stay convergence hole that is provided with on it, on described spring radius stay, the round screw thread compression spring is housed, the tail end of above-mentioned rim piece is provided with the pintle of band circular hole, connection between the described rim piece can be in the groove of the wheel wing of one of them the rim piece wheel wing that inserts another adjacent rim piece, and in the circular hole of described pintle caging bolt is housed and realizes.
Above-mentioned rim piece can by the wheel body and be located at this take turns the body both sides not the wheel wing of concentric, different radii arc surfaced member constitute, in wheel body part, also can be provided with spring radius stay convergence hole.Damping wheel also can be designed to the wheel be made up of eight rim pieces, also can be designed to be less than or more than the damping wheel of eight even number rim pieces according to different car types, different wheel load amount needs and different wheels footpath.
In other words, the structure major part of damping wheel is made up of rim piece, bearing and round screw thread compression spring.
The rim piece is by the wheel wing and the wheel body of concentric, different radii arc surfaced member are not formed.The wheel body spring radius stay convergence hole of rim piece closely is connected the cylindrical spring radius stay that is fixed on the bearing, and wheel body spring radius stay convergence hole is reserved certain depth, is hit the masterpiece time spent at damping wheel, and ammunition feed spring radius stay is flexible.Damping wheel is exactly the round and elastic structure of being made up of above-mentioned those members.
This damping wheel is compared the effect that is had with existing wheel:
Self-evident; operating vehicle will be subjected to impulsive force inevitably to the traffic blows effect; the effect of damping wheel is: when impact force action during in damping wheel, the special entity in the wheel is made the best use of the situation; impulsive force is discongested; change its intrinsic direction of transfer, make it result from wheel road contact point, after mechanism decomposes, synthesizes new making a concerted effort in wheel; act on the road surface by wheel road contact point again, thereby the protection car body is avoided the impact of impulsive force.
The pipeline of damping wheel blocking-up impulsive force as in existing wheel makes it tune and returns the road surface, thereby protected the be not hit harm of power of car body, and this is the peculiar function of damping wheel.Under impulsive force continuation effect, the spring of damping wheel is compressed, and shorten in the wheel footpath, core wheel moves down earthward and draws close, and meanwhile, the also synchronous equivalent of vehicle's center of gravity moves down, wheel disk and vehicle's center of gravity relative distance do not change, and two in the heart without any the transitive relation of power.Situation of change during the backwash of wheel spring, two in the heart relations are also followed this rule.
This situation shows that damping wheel has been eliminated the impact of impulsive force to vehicle, makes vehicle avoid vibrations, avoid destroying, and the so excellent shake function of removing is that attribute by damping wheel is determined.
Damping wheel also has a significant advantage: aspect operating vehicle is braked, when using damping wheel, not only protected traffic safety but also efficient.
Railroad train is carried out emergency braking is example.When train is carried out emergency braking, a bigger total brake shoe pressure is added on the wheel wheel face, because damping wheel is an elastic structure, under the brake shoe pressure effect, spring in the wheel is compressed gradually, brake shoe pressure is converted into the braking force to wheel, also is an ascending progressive formation, and is a unexpected reinforcing unlike existing wheel.If two kinds of wheels are once applied onesize braking force, afterburning time the same length, effect is just very different so.For damping wheel, no matter once afterburning much, how of short duration the time is, affact braking force on the wheel and be grow from weak to strong, ascending process, in this process, the powerful kinetic energy that the train high-speed cruising is had, correspondingly overcome gradually, the instantaneous running velocity of train also lowers gradually along with the ascending variation of braking force from high to low.When finally making wheel, braking force stops operating, the running velocity of train has been reduced in the safe range or near safety speed, the force of inertia of train weakens greatly, thereby the extent of damage that emergency braking may cause reduces greatly, thereby has guaranteed traffic safety.Under same case, existing wheel is carried out emergency braking, once reinforcing is too big, and train momentum can not get overcoming, and wheel just stops operating, and sizable wheel sliding-frictional resistance makes train be subjected to great impact, so that cause train operation accident.
The high performance of damping wheel aspect the railroad train braking.Accomplish guaranteeing under the prerequisite of traffic safety, adapt to the actual needs that increases the braking dynamics, thereby improved the railroad train brake efficiency, satisfy the desirability that train running speed improves in railway interests.Other vehicles are used damping wheel, also can produce same effect in this respect.

The specific embodiment
Round and elastic structure shown in Figure 1, that this damping wheel is made up of eight rim pieces 1, bearing 3 and round screw thread compression spring 2 is equipped with wheel shaft 4 in bearing 3.Rim piece 1 is sleeved on the spring radius stay of bearing 3 by the spring radius stay convergence hole that is provided with on it, and round screw thread compression spring 2 is contained on the spring radius stay.Connection between the rim piece 1 is in the groove of the wheel wing 2 of one of them the rim piece 1 wheel wing 2 that inserts another adjacent rim piece 1, and the installing caging bolt is realized in the circular hole of wheel wing pintle.
Shown in Figure 2, the rim piece by the partial sum of wheel body 1.2 be located at this take turns body portion both sides not the part of the wheel wing 1.1 of concentric, different radii arc surfaced member constitute, in this part, also be provided with spring radius stay convergence hole 1.3 at wheel body 1.1.The tail end of rim piece is a wheel wing pintle 1.5 that is provided with circular hole.
Shown in Figure 3, the one side wheel wing of rim piece overlooks to see at cross central line it is the single ring-type bar of one section arc, another side wheel wing is overlooked and is seen the double-ring bar that is provided with the two-section arc in the cross central line both sides, forms the wheel wing telescopic chute of the adjacent single ring-type bar wheel of another rim piece wing of the insertion that just in time can insert another rim piece at the wheel wing middle part that the double-ring bar constitutes.
Shown in Figure 4, bearing is mounted in it on the spring bearing 3.3 that wheel shaft 4 is housed along the spring radius stay line of centers 3.2 that is " rice " font by eight spring radius stays 3.1 and constitutes.
Wheel is in rolling, and anywhere the rim piece power that is hit is impacted, and the stressed member that stands in the breach is the wheel wing.So, is damping wheel how to realize eliminating impulsive force to the impact of vehicle? with impulsive force transmittance process from importing into to spreading out of in wheel, be illustrated below.
1, act on the entad component that traffic blows power was decomposed into some even number equal and opposite in directions in the wheel arbor square section, direction sensing wheel disk by wheel road contact point.
(1) wheel wing intrados design.
In damping wheel, impulsive force is decomposed into entad component of some even numbers, and then after reversing each minute power transmitting, synthetic again force action is the rim piece in the ground-surface major part.Understand the decomposition of force process, start with, referring to accompanying drawing 5 (contrast is referring to accompanying drawing 2,3,4) from clear and definite rim piece principle of design.
Among the figure, O is the wheel center of circle (or claim wheel disk 1.1.11, as follows), OO

The wheel wing 1.1 on each rim piece of damping wheel constitutes the whole rim of wheel, when rim is subjected to the impulsive force impact, if, the rim piece on its right side of rim piece as shown in Figure 5 is subjected to impact force action, so, right side rim piece is overlapped on the wheel wing on this rim piece wheel body 1.2, with A
3C
1Camber line is that slide relative is made in the contact position of cambered surface, and the wheel wing stretches into wheel wing telescopic chute 1.1.3, and forces the displacement of rim piece.Because the spring radius stay convergence hole 1.3 on the rim piece wheel body 1.2 closely is connected spring radius stay 3.1, the rim piece can only move along spring radius stay 3.1 directions, meanwhile, the wheel wing of rim piece two Side forces the rim piece about adjacent also to do identical displacement, the size of their displacements is taken turns wing intrados 1.1.2 and is restricted.Take turns wing intrados principle of design as can be known from above-mentioned, force the two-wheeled wing intrados 1.1.2 radius of adjacent two rim piece displacements to equate, and the two places wheel wing 1.1 is equidistant with the wheel wing intrados 1.1.2 center of circle with wheel body 1.2 contact points (being face actually), obviously, the displacement of adjacent two rim pieces be according to equicrural triangle dwindle when enlarge changing two waist length also simultaneously equivalent shorten the principle that increases and change, thereby, the displacement of adjacent two rim pieces equates, and is all like this until the displacement of each rim piece of whole wheel.
More than discussed impulsive force and made each rim piece do the equivalent displacement, that is to say that impulsive force just is broken down into equal-sized component after importing damping wheel into.Because it is in the cross section disk of axle at center that each spring radius stay 3.1 cloth of damping wheel bearing are listed in wheel disk 1.1.11, and the line of centers of each spring radius stay 3.1 intersects at core wheel, thereby the impulsive force component that is decomposed and obtains at damping wheel, its value size not only equates, and all be positioned at same disk, direction is all pointed to core wheel.Damping wheel as shown in Figure 1 can be decomposed into impulsive force eight equal and opposite in directions, and direction is pointed to the radial centripetal power of core wheel.
(2) wheel wing extrados design.
The extrados of the wheel wing 1.1 constitutes the damping wheel wheel face.Under the uninterrupted effect of the impulsive force that differs in size, vehicle wheel footpath size is also constantly along with variation.Yet the wheel wing extrados 1.1.1 radius that constitutes the wheel wheel face is changeless, and therefore, damping wheel is often to be under the continuous situation that changes of outer circularity to move, and this situation is that damping wheel is inevitable.But should see, make it not influence the vehicle operating, also exist the possibility that makes wheel be in operation under the best outer circularity state except accomplishing to make damping wheel cylindrical out of roundness in a very little scope, to change from design.
When the fully loaded normal speed of vehicle was moved, wheel had been subjected under the most common at most impact force action, and the spring amount of being compressed of damping wheel is set at Δ L

5Obviously, such wheel wing extrados 1.1.1 can make damping wheel put into operation with the outer circularity of the best.
Also need explanation, the circular hole on the wheel wing pintle is used for bolt, and the wheel wing 1.1 is linked up with adjacent rim piece, its tightness degree otherwise hinder the wheel wing 1.1 to slide in taking turns wing telescopic chute 1.1.3.In addition, the design of wheel face shape will be a foundation according to different car type needs, different as the wheel face of rolling stock and automobile, and the wheel face of automobile, motor bike, bicycle will be designed to " U " shape groove, so that tire is installed.When definite " U " shape groove depth, consider that vehicle may be subjected to maximum impact force, when vehicle wheel footpath shortening amount reached maximum, wheel tyre did not come off and is foundation.
2, make each entad component realizable force (work done) can two-way conversion, the break-in mental and physical efforts are centnifugal force, and then synthetic make a concerted effort with impulsive force is reciprocal, act on the road surface in taking turns the road contact point.
For being eliminated, damping wheel causes vehicle vibrations and the impulsive force that destroys, above-mentioned an impulsive force is decomposed into some equal-sized entad component after, for the final impulsive force of eliminating has been created condition to the deleterious effect of car body, and realizable force (work done) can two-way conversion be to guarantee to eliminate the theoretical basis that impulsive force impacts car body, and the bearing of damping wheel is the technical guarantee that this theory is come true.
See the bearing of the damping wheel shown in the accompanying drawing 4.Bearing has eight bearing spring-loaded faces, is divided into four pairs, is the center with the wheel disk, arranges face to face, constitutes octahedra bearing.In damping wheel, the wheel body line of centers of rim piece, spring radius stay 3.1 line of centerss that are connected with the wheel body overlap, and the line of centers 3.2 that is vertically fixed on eight cylinder spring radius stays 3.1 of bearing spring-loaded face center not only is positioned at the wheel disk, intersect at wheel disk, and the line of centers 3.2 of spring radius stay 3.1 facing each other is all straight line.Thereby be sleeved on spring on the spring radius stay 3.1, and in the time spent of doing that is subjected to power, pass the power of coming by spring, all be to be mutually 180 degree reversing senses in pairs to act on the bearing.
Hence one can see that, damping wheel as shown in Figure 1, when wheel road contact point is subjected to impact force action, impulsive force is broken down into eight component in wheel, act on the bearing 3 via spring 2, the bearing 3 of this moment is subjected to four groups of equal and opposite in directions simultaneously, the effect of the power that direction is opposite, in this case, bearing 3 is can not produce to any direction displacement, obtain two important conclusions thus: one, on the wheel shaft 4 that does not have impulsive force to be delivered to be positioned at the bearing center and be fixed together with bearing 3, the car body that nature and wheel shaft 4 combine as a whole is not subjected to the effect of impulsive force yet: they are two years old, bearing spring-loaded face becomes the fixed end of circular compression spring 2, and the wheel body spring-loaded face of spring 2 other ends is a movable end.Therefore, spring 2 has had fixed end, when movable end is stressed, make by force compresses spring 2 works done in bearing 3 blocking-up outlets, finishes by power → (work done) transformation of energy, and energy storage is in the spring 2 that has compressed.After the current impact force action of wheel road contact point was over, before next impulsive force arrived, spring 2 backwashes discharged energy stored, carried out the conversion between energy (work done) → power.At this moment, the damping wheel rim enlarges, but this expansion trend is subjected to the ground-surface restriction at wheel road contact point, makes a concerted effort so form, and this power affacts on the road surface at wheel road contact point.
So far, damping wheel has been finished the one-shot decomposition of force, then carry out two-way conversion between power (work done) energy, form the process of newly making a concerted effort, it makes impulsive force arise from wheel road contact point, and impulsive force is not via car body, terminate in wheel road contact point again, thereby the vehicle body except that wheel, avoid the influence of impulsive force, guaranteed traffic safety.
To this, the above-mentioned demonstration of having done on the angle of its center of gravity moving characteristic of object receiving force, is done further to discuss below.
We know whether show an object receiving force, see whether the center-of-gravity position of this object changes to some extent.On the physical significance of strictness, even to a great object of quality, apply an extremely small power and be applied to it, this object also can produce small distortion, and its center of gravity also can produce micro displacement.Below to damping wheel and existing wheel after being subjected to impact force action, relatively their core wheel one below and the relative distance situation of change of body gravity, the checking damping wheel except that shaking function.
Accompanying drawing 6, be existing wheel and damping wheel under impact force action, their core wheel change in location scheme drawings.
Abscissa OT axle had both been represented the time, also represented the wheel disk masterpiece time spent present position that is not hit that is in operation.Ordinate OS represents the side-play amount of wheel core wheel under impact force action.Obviously, the vehicle's center of gravity position is higher than the wheel disk position, then is positioned at somewhere, OT axle top.

3Existing wheel of expression and damping wheel are subjected to the effect of one-shot power separately respectively, the two wheel disk change in displacement trajectories of ending when this time impact force action is over when stressed.
The existing wheel power effect core wheel deformation trace line that is hit, be positioned at OT axle top, this is because existing wheel is a rigid body, when being subjected to impact force action, wheel disk is drawn close to the vehicle's center of gravity that is positioned at its top, and the relative distance of core wheel and vehicle's center of gravity shortens, at this moment, car body is subjected to passing the impulsive force of coming by wheel and impacts, and produces vibrations, rocks.It is big more to act on traffic blows power, and two in the heart relative distance shortening amounts are also big more, and the impact of the impulsive force that car body is subjected to is also serious more.

3, its meaning shows: under impulsive force continuation effect, the spring of damping wheel is compressed, shorten in the wheel footpath, and core wheel moves down earthward and draws close, meanwhile, vehicle's center of gravity also synchronously equivalent move down, wheel disk and vehicle's center of gravity relative distance is change not, two in the heart without any the transitive relation of power.Situation of change during the backwash of wheel spring, two in the heart relations are also followed this rule.
This situation shows that damping wheel has been eliminated the impact of impulsive force to vehicle, makes vehicle avoid vibrations, avoid destroying, and the so excellent shake function of removing is that attribute by damping wheel is determined.
Except that above-mentioned embodiment, damping wheel can be applicable on the various vehicles, as the wheel as bicycle, motor bike, automobile, rolling stock, also can be used as the landing wheel of aircraft, or the like.In broad terms; damping wheel is actual to be to make mobile avoid the fender guard that impulsive force destroys; be new machinery; be used for protecting the be hit main body of power impacted object to exempt from destruction, avoid vibrations, related face is very wide; as prevent to be subjected to when weight from falling vibrations to be collided; avoid the hand electric pneumatic pick to the insufferable vibrations of operator, or the like the aspect, all remain Application and Development.
