Problems solved by technology

Approaches with new friction plate materials risk increased cost, reduced face life and need to redesign clutch parameters
The method of reducing the compression force of the diaphragm spring will increase the sliding time when the clutch is engaged, which may cause the risk of burning the friction plate

Embodiment Construction

[0013] refer to figure 1 , a method for improving clutch output torque stability in the process of starting a car, comprising the steps of:

[0014] (1) Measure the free thickness of the friction plate 6 of the driven disc. For example, the free thickness requirement of a Φ200 driven plate is 8.3±0.3mm; the pressing thickness requirement is 7.7±0.3mm; adjust the distance between the grinding plate 1 and the grinding wheel 2 to 8mm;

[0015] (2) Install the driven disc assembly 4 on the mandrel, and fix the mandrel on the top of the grinding machine; adjust so that the A side 6-1 of the friction plate is fully in contact with the 2 sides of the grinding wheel;

[0016] (3) Set the grinding parameters of the grinding machine, and the power base 3 drives the grinding wheel 2 to grind at 1000 rpm;

[0017] (4) The friction plate 6 of the driven disk is between the pressure plate 1 and the grinding wheel 2, and it is ground by the elastic force of the corrugated plate 5, and the ...

Abstract

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.

Description

technical field [0001] The invention relates to automobiles, in particular to a method for improving the clutch output torque stability during the starting process of the automobile. Background technique [0002] During the starting process of the car, due to the periodicity of the engine torque output, the output torque of the clutch will fluctuate, which may cause chattering of the whole vehicle in severe cases. The greater the clutch output torque fluctuation, the more obvious the chattering phenomenon of the whole vehicle. There are many factors that cause clutch output torque fluctuations, including matching with the engine, clutch pressing force, friction coefficient of clutch friction plate, size of clutch pressure plate, stiffness of shock absorber, deflection of clutch driven plate, driver’s driving technology, etc. Wait. However, in the existing methods, new friction plate materials are mainly used and the compression force of the diaphragm spring is reduced. Ap...
