Diaphragm spring clutch with self-adjustment mechanism

Abstract

The invention provides a diaphragm spring clutch with a self-adjustment mechanism and belongs to the technical field of clutches. The invention aims at providing the diaphragm spring clutch with the self-adjustment mechanism, which carries out compensation on the wear of a pair of friction plates so as to improve the driving comfort of a driver. A ratchet wheel is coaxially fixedly connected with a screw, an adjusting nut is arranged on the screw in a sleeving manner and is meshed with the screw through threads, and the tail end of the adjusting nut is inserted into a notch of a lower adjusting ring. The outer ends of the ratchet wheel and the screw are separately connected to a support through shafts, and the support is mounted on a clutch pressing disc through nails. A pawl and a pressing plate are fixedly mounted on a clutch cover through rivets, and the lower end of the pawl is pressed against the teeth surface of the ratchet wheel. A locking component is fixedly mounted on the clutch pressing disc, and an upper adjusting ring and the lower adjusting ring are placed in an annular groove of the clutch pressing disc. A limiting tongue piece at the lower end of a limiting component is inserted into a limiting groove. After the friction plates are worn, the wear of the friction plates is compensated through the self-adjustment mechanism, the initial angle of a diaphragm spring is kept unvaried, and a great role is played on improving the comfort of the driver.

Description

technical field [0001] The invention belongs to the technical field of automobile clutches. Background technique [0002] The automobile clutch plays multiple functions such as torque transmission, power cut off, vibration reduction and overload protection in the transmission system, and its quality affects the performance of the entire vehicle. During the running of the car, the coupling and disengagement of the clutch will wear the friction plate, resulting in a larger separation force of the clutch ( Figure 9 ), the pedal force of the car will gradually increase. If it is greater than the driver's adaptable force, it will affect the driver's driving experience and the driver's driving comfort. In order to improve the driving comfort of the driver, it is necessary to maintain the initial installation angle of the diaphragm spring in the clutch. As long as the initial installation angle does not change, the separation force will not change. [0003] When the clutch is wor...

AI Technical Summary

Problems solved by technology

[0003] When the clutch is working, since the two sides of the friction plate will have relative friction with the surface of the flywheel and the surface of the pressure plate, as the use time increases, the wear of the friction plate will increase. At this time, the diaphragm spring in the clutch assembly As the installation angle increases, the pressing force will gradually increase ( Figure 9 ), the separation force also increases ( Figure 7 ), the pedal force of the clutch will also increase accordingly, and the pedal will become heavier and heavier, which will have a greater impact on the driver's driving experience
