Description

technical field [0001] The invention belongs to the technical field of automobile parts. Background technique [0002] When the car starts and shifts, the engine output power is interrupted and transmitted through the separation and combination of friction plates between the active part (connected to the engine) and the driven part (connected to the transmission input shaft) of the clutch. [0003] At present, the clutches used in the automotive industry are all friction clutches. But there are many defects in this product, because product performance and structure reason, these defects can't be solved. Mainly manifested in the following aspects: [0004] 1) Short service life of the clutch [0005] Because the currently used friction clutch transmits power by the friction of the main and driven friction plates, during the gear shifting process, the main and driven friction plates wear very seriously, which shortens the effective service life of the friction plates.

AI Technical Summary

Problems solved by technology

[0004] 1) Short service life of the clutch

[0005] Since the currently used friction clutches transmit power by the friction of the main and driven friction plates, the wear of the main and driven friction plates is quite serious during the shifting process, resulting in shortened effective service life of the friction plates

[0006] 2) Large impact, high noise, reducing the life of parts

[0007] In the process of shifting, due to the large inertia of the vehicle, the speed difference between the main and driven friction plates is large, and the combination is rapid after the shift is completed, resulting in large noise and impact, so the service life of the drive train components will be greatly reduced

[0008] 3) Serious pollution

[0009] Since the friction plate contains toxic asbestos products, the asbestos dust that wears off flies into the air, causing great pollution to people and the ecological environment

[0010] 4) Unstable work

[0011] Because the separation and recombination process of the clutch produces a large amount of sliding friction work, which generates a large amount of heat and cannot be dissipated in time. The light one will deform the clutch, resulting in a reduction in the contact area of ​​the friction plate, increasing the amount of wear, and reducing the service life; the severe one will be burnt and scrapped.

In addition, as the temperature rises, the coefficient of friction is unstable. Under the condition of constant pressure, the torque transmitted by the clutch changes with the temperature, thus causing unstable operation.
