Description
Technical field
The present invention relates to the vehicle clutch driven disc assembly structure, particularly a kind of clutch driven disk for automobile with double wave shape chip architecture of the spring.
Background technique
Clutch is parts direct in the car transmissions and that motor interrelates, it is responsible for cut-out and the combination of power and transmission system, it is in cut-out and combination, energy gentle start when guaranteeing vehicle starting, the smooth-going switching of energy when shifting gears simultaneously, therefore clutch driven disc assembly is the effect of playing " taking over from the past and setting a new course for the future " at cut-out and the cohesive process of power and transmission system, namely receives the transmission power of motor, gives follow-up transmission system with the power transmission of reception simultaneously.
In the prior art, vehicle clutch driven disc assembly structurally usually is divided into and the monophasic waveform spring sheet is housed and not with the structure of wavy spring sheet, wherein monophasic waveform chip architecture of the spring clutch drived disk assy is to have assembled a wavy spring sheet between two friction plates on the driven disc, utilize the elastic force of this spring sheet make clutch drived disk assy with the cohesive process of platen assembly in guarantee that the torque that clutch transmits increases in mild mode, so just allow clutch under the lower rotating speed of motor, to engage, avoid in joint, forming and impact, thereby prolong the working life of friction plate, and reach the prolongation clutch drived disk assy purpose in working life.
Not with the driven disc normal operation of wavy spring on two-plate clutch, the employed clutch drived disk assy of two-plate clutch does not generally have axial elasticity, at first be because the cohesive process of two-plate clutch itself is just more smooth-going, secondly, if making, the two-plate clutch clutch drived disk assy has the axial elasticity structure, consequently to greatly increase the working stroke of pedal or dwindle the velocity ratio of clutch transmission and increase the steering force of pedal, can thoroughly separate with this guarantee clutch, obviously, these all are unfavorable for the lock out operation of clutch.
And in existing monophasic waveform spring sheet clutch driven disc assembly, for guaranteeing the elastic reaction of spring sheet, the spring sheet that assembles is made into wavy waveform configuration, its waveform amount is generally between 0.8 ㎜～1.1 ㎜, the approximate trend of Flexible change rule (namely axially loading the relation with its distortion) is parabola shaped, i.e. stressed less when beginning to be out of shape is then along with the increase of distortion, the increase of power is very fast, until be driven plain.Because automobile in the process of moving, the combination of clutch is very frequent with lock out operation, therefore the elastic performance of spring sheet is just very important, for the monophasic waveform spring sheet, its anti-bullet go down performance be easier to the decay, its attenuation process can follow its waveform amount to reduce gradually, even become spring sheet without the waveform amount, this moment, therefore binding ability and the gearing meeting of driven disc reduced or inefficacy gradually, can not embodying in conjunction with smooth-going performance of clutch drived disk assy, consequent consequence is: the smoothness in the stationarity of vehicle starting and when gearshift is variation even disappearance, can cause that thus automobile produces shake and impacts and damage clutch when starting.
Summary of the invention
The present invention is a kind of clutch driven plate with double wave shape spring sheet that proposes for solving the problems of the technologies described above, this driven disc adopts double wave shape spring sheet combination structure, driven plate structure by the clutch drived disk assy that diameter is larger in the original technology of double wave shape spring plate group Partial Replacement, thereby can reduce the rotary inertia of driven disc and the disengaging performance of raising driven disc, significantly improve thus the ability of clutch drived disk assy driving torque and the reliability of work, make driven disc can adapt to the motor of larger output torque.
For solving the problems of the technologies described above, the present invention is equipped with the double wave shape spring plate group that two identical wavy spring sheets of shape form between two friction plates of the monophasic waveform spring sheet clutch driven disc assembly of original technology; Two wavy spring sheets are integrated with closing-up symmetrically, and two wavy spring sheets are integrated with two friction plate rivet clasps respectively by rivet.
The spring sheet of spring plate group roughly all is milder wavy S shape, its waveform height is about 1/2 of former monophasic waveform spring sheet waveform height, after two spring sheets make up with symmetric mode, the waveform height of spring plate group is identical with the waveform height of former monophasic waveform spring sheet, can be installed in the clutch driven plate of prior art thus.
Since the waveform height of each wavy spring sheet of double wave shape spring driven disc of the present invention only to be former monophasic waveform spring sheet waveform high half, therefore they have less amount of plastic deformation and the stronger elastoresistance performance that goes down, behind two wavy spring sheet Symmetric Composites, the non-deformability of wavy spring sheet group can strengthen greatly, under average service conditions, can the long period keep original waveform amount and shape, thereby energy gentle start in the time of can guaranteeing vehicle starting, smooth-going when guaranteeing simultaneously gearshift, this plays an important role to stationarity and the aspects such as travelling comfort and working life thereof that improve clutch operating.
