Method improving stability of output torque of clutch in starting process of automobile

The invention discloses a method improving the stability of the output torque of a clutch in the starting process of an automobile. According to the method, through a special grinding tool, a specific surface of a friction plate of a driven disc of the clutch is ground, the other surface keeps unchanged, and therefore unstable connection of a driving disc and the driven disc of the clutch due to deflection can be eliminated, fluctuation of the friction torque between the driving disc and the driven disc of the clutch in the starting process of the automobile can be effectively reduced, and the shaking phenomenon in the starting process of the automobile can be alleviated. According to the method, a new solution idea and method are proposed, and the output torque of the clutch can be stable. The method is easy to implement and low in cost, and the homogeneity of products can be guaranteed easily.
