Motor car engine train is the power transmission mechanism of motor car engine annex, its general belt transmissioning mode that adopts drives engine accessory power rating running, because motor rotating speed and output torque under different operating modes constantly change, belt tension and train planeness also can change thereupon, make train run stability variation, this is not only related to the working life of belt, but also can produce noise, causes adverse effect to vehicle NVH performance.
In motor car engine train, generator belt wheel is one of key factor affecting train run stability, for alleviating the overtired problem that in engine wheel system, belt tension frequent variations causes, the at present configuration on automobile current generator overrunning belt pulley (OAP), the application for a patent for invention file that is CN201110031531.3 as application number discloses a kind of diesel engine Wheel train driving gear with overrunning belt pulley, it changes generator pulley for overrunning belt pulley, described overrunning belt pulley is by belt pulley, Internal and external cycle framework, contact seal, centripetal needle bearing, seal washer and axle sleeve composition.Inside and outside ring box is placed between belt pulley and axle sleeve, and the end face of belt pulley and inner ring framework one side is equipped with contact seal, is provided with clutch roller and spring in the space that Internal and external cycle framework forms.Although the technological scheme of this patent application makes the drivign belt can only unidirectional drive generator, thereby avoid in engine retard process belt excessive slip and rock, having reduced the impact of generator on belt drive system.But it is inoperative under motor acceleration and normal operation, and can not meet the demands because Generator Vibration causes train planeness in the time that generator mode is unstable, has accelerated the wearing and tearing of belt.
Model utility content
The purpose of this utility model is the drawback for prior art, provides a kind of and can under Under Different Work Condition of Engine, all can realize stabilising wheel running state, extends the generator overrunning belt pulley of the motor car engine train in belt working life.
Problem described in the utility model realizes with following technical proposals:
A kind of generator overrunning belt pulley of motor car engine train, it is provided with overrun clutch structure, described free wheel device comprises inner ring, outer ring, one group of shock-absorbing spring and one group of roller, the fixing assembling of described inner ring and generator shaft, along inner ring, the groove that one group of quantity is mated with shock-absorbing spring and roller is circumferentially evenly set, the fixing assembling of described outer ring and pulley disc, described shock-absorbing spring is placed in the cavity between inner ring and outer ring, its one end is connected with roller, the other end is fixed in inner ring recess sidewall, its specialization is: the inwall of described outer ring is provided with outer ring vibration damping layer, described interior ring outer wall is provided with inner ring vibration damping layer, described roller outer surface is provided with roller vibration damping layer.
The generator overrunning belt pulley of above-mentioned motor car engine train, described outer ring vibration damping layer is the rubber damping layer of direct sulfidization molding processing on the inwall of outer ring.
The generator overrunning belt pulley of above-mentioned motor car engine train, described inner ring vibration damping layer is the rubber damping layer of direct sulfidization molding processing on interior ring outer wall.
The generator overrunning belt pulley of above-mentioned motor car engine train, described roller vibration damping layer is the direct rubber damping layer in the processing of roller outer surface sulfidization molding.
The generator overrunning belt pulley of above-mentioned motor car engine train, described roller is rigid material roller.
The utility model utilizes overrun clutch structure to realize the object of stabilising wheel running state, when motor is in accelerating or when accidental conditions, roller is compressed by inner ring and outer ring, free wheel device is in jointing state, inner ring, roller and outer ring run-in synchronism, Generator Vibration energy is absorbed by inner ring vibration damping layer, roller vibration damping layer and outer ring vibration damping layer; When motor is in the time running slowly operating mode, inner ring is at inertial force effect lower compression shock-absorbing spring, and roller slides to inner ring groove, free wheel device is in off state, outer ring separates with inner ring, and now motor does not provide driving force to generator, belt load unloading.In a word, the belt tension that the utility model has not only been avoided Engine torque to change and brought changes, but also has overcome the train running unstable problem causing because of Generator Vibration, has reduced the frequency of impact to belt, has improved the working life of belt.
