Background

The automobile need carry out the speed governing (shift promptly) under the condition according to the difference at the driving in-process, because the output shaft of engine rotational speed can change when the speed governing of shifting just so has the difference with the rotational speed of wheel, consequently need with its disconnection reconnection after shifting gears reconnection, what need be used here is the clutch, utilize driven plate and flywheel time friction drive, the diaphragm spring separates driven plate and flywheel after the pressure that receives the footboard, the restriction of disconnection transmission and removal power again after accomplishing shifting gears lets flywheel and driven plate follow on the friction carry out the transmission, but it still can have certain problem at the during operation:

1. when carrying out the during operation, the utilization be the pressure disk will press on the driven plate surface, thereby it can part to make driven plate and flywheel to warp through the peripheral perk of diaphragm spring drive pressure disk, but cause the incomplete or the low condition of degree of accuracy of perk when utilizing diaphragm spring to press dynamic pressure disk easily, in addition all link together through friction drive between driven plate and flywheel and the pressure disk, will produce great sliding friction between the two after the car carries out the variable speed, will produce more heat like this, and the heat is too high will influence the frictional force and the life of friction disc.

2. The driven plate is internally provided with a damping spring for damping, namely, the torque between the flywheel and the driven wheel is reduced through the energy absorption effect of the spring, but in practice, after the vibration is transmitted to the whole clutch, because the damping spring can only buffer the axial vibration in the radial direction, but can not play a good damping effect, after long-term use, the situation of flutter can occur, namely, a gap is generated between the driven plate and the flywheel or between pressure plates, and meanwhile, the structure of the pressure plate can also cause uneven contact between the driven plate and the flywheel after the pressure plates are damaged, so that the situations of slipping of the clutch and sound generation can also be generated.
