Description
Technical field
It is compound more particularly, to a kind of double frequency bending for car transmissions the invention belongs to dynamic vibration absorber field
Formula dynamic shock absorber.
Background technology
With the fast development of domestic automobile industry, people gradually step up to the attention rate of passenger car comfortableness, to vehicle
NVH(Noise, Vibration and Harshness, i.e. noise, vibration and injustice are pliable)The requirement more and more higher of performance.Multiply
With car in the case where comfortableness and handling trend is pursued, frequently with front-engine rear-drive or the drive arrangement mode of four-wheel drive.Due to
The presence of power transmission shaft, easily twisting vibration is caused under the excitation of engine, while easily evoking the mode of flexural vibration of power train
Low-frequency vibration, the noise that thunders in vehicle ride room is triggered so as to the resonance for causing vehicle body and miscellaneous part, has been had a strong impact on and has been multiplied
Sit comfortableness.
Type of drive be the vehicle of front-engine rear-drive or four-wheel drive in the process of moving, more in rotating speed 1000-2000rpm models
Evoke the torsional resonance mode and flexural vibration mode of power train, comfortableness and transmission of this compound vibration to vehicle in enclosing
The service life of based part brings serious adverse effect.In the case where power train part is not changed, inhaled by setting up power
Shake device, can largely solve the problems, such as or reduce vehicle drive line vibrations noise.
In order to solve the vibration of torsion mode, on domestic market using it is more be single-frequency torsional vibration damper, i.e., only
There is an intrinsic frequency, the vibration noise of the torsion mode of certain frequency range of power transmission shaft can only be solved.It is curved in order to solve power train
The vibration of bent mode, relatively conventional is the dynamic vibration absorber or the dynamic absorber that is assemblied in transmission shafts of power transmission shaft cluster
Device, can only equally solve the flexural vibrations of single frequency range.Resonance to solve power train torsional direction and bending direction simultaneously
Mode, then need to assemble the dynamic vibration absorber of different directions, considerably increases development time and the cost of dynamic vibration absorber.And
Currently a popular torsional vibration damper majority is not provided with axial limiting, anti-loosening protector, has had a strong impact on the tired of torsional vibration damper
Labor life-span and the safety of vehicle drive system, cause vulcanized rubber to tear under limiting condition, or even mass departs from, and destruction is passed
Dynamic system and chassis part, jeopardize traffic safety.
The content of the invention
It is an object of the invention to solve the above prior art presence deficiency, there is provided a kind of simple structure, it is easy to process,
The safe and reliable bending combined type double frequency dynamic vibration absorber for car transmissions.
To solve above-mentioned technical problem, the technical solution adopted by the present invention is:
A kind of double frequency composite power bump leveller for automotive transmission, including tubular the second mass, be arranged on it is described
Mounting flange in second mass inner circle, the outer end edges of second mass extend internally, and to be provided with annular stop convex
Platform, is provided with the spacing rubber of tubular of one end sealing between the end face and positive stop lug boss of the mounting flange, described is spacing
The openend of rubber is towards being provided with the annular that is integrated with adpting flange side surface vulcanization in mounting flange and endoporus
First block rubber, parcel is provided with the first mass of annular in first block rubber, the inner ring of described the second mass
Press-in is provided with and makes the second mass and the close-fitting ring of mounting flange between face and the mounting flange outer circumference surface
The block rubber of shape second.
Further, the mounting flange outer circumference surface is circumferentially arranged has cydariform raised.
Further, it is triangle cydariform that the cydariform is raised, and it is shaped as triangle of the drift angle in arc transition.
Further, it is SPL cydariform, its shape SPL shape that the cydariform is raised.
Further, the second described mass inner ring surface is provided with and the raised consistent cydariform groove of cydariform.
Further, the adpting flange side surface is provided with and is provided with the mesopore matched somebody with somebody with drive shaft cartridge and some circumferentially equal
The pilot hole of even distribution.
Compared with prior art, the bending combined type double frequency dynamic vibration absorber of car transmissions of the present invention has following excellent
Point:
1. two problems of different directions power train resonant frequency are can solve the problem that, has both two kinds of dynamic absorbers of different action directions
Device vibration-damping function.
2. product structure is spacing compact, and spacing place has vulcanized rubber to buffer, and can both limit mass and not have significantly
Displacement, it is to avoid there is abnormal sound during collision, can well ensure that the life-span of product will not premature failure again.
3. the mass and ring flange of torsional direction eliminate this portion using the press-in rubber compounding mode of drum organization
The work flow of the vulcanization of rubber for dividing, simplifies processing technology, is easy to being integrally formed for dynamic vibration absorber.
4. two masses are provided with anti-loosening protector, improve the security reliability of product, it is easy to by adjusting rubber
The weight of the formula of glue material and control mass adjusts the intrinsic frequency of double frequency dynamic vibration absorber.
5. product structure is simple, processes and convenient disassembly, and the vehicle that can apply to various front-engine rear-drives or four-wheel drive is passed
Dynamic system.
