Clutch with double adjustment effect on pressure of pressure plate

Abstract

The invention discloses a clutch with a double adjustment effect on the pressure of a pressure plate. The clutch with the double adjustment effect on the pressure of the pressure plate comprises a driving plate, the pressure plate and a transmission assembly, wherein the driving plate and the pressure plate are coaxially mounted together in a sleeving manner and are in running fit with each other; gear teeth are arranged on a running fit surface of the pressure plate; the transmission assembly comprises floating blocks which are mounted on a running fit surface of the driving plate in a floating manner in the radial direction and can be engaged with the gear teeth to implement transmission; and the transmission assembly further comprises a inertial disc and push blocks which are used for adjusting the magnitude of an acting force between the floating blocks and the gear teeth. According to the clutch with the double adjustment effect on the pressure of the pressure plate, equal-torque output can be realized when the tangential direction angle of a point of action between the floating blocks and the gear teeth is large, the torque transmitting ability is high, the dynamic performance is good, meanwhile, the floating blocks are in non-frictional fit with the gear teeth, the problems of frequent repair and short service life due to abrasion of components can be avoided, and repair cost is reduced; and moreover, the pressure of the pressure plate can be adjusted automatically according to the rotating speed of the driving plate, the pressure is increased in an accelerating process, and therefore, the stability of clutch engagement transmission is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a pressure plate pressure double-adjustable clutch. Background technique [0002] During the driving process of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the transmission, so as to cut off or transmit the power input from the engine to the transmission. The clutch is a common part in mechanical transmission, which can separate or engage the transmission system at any time. At present, the clutches used in vehicles mostly adopt a friction structure, and the clutch transmission is realized through the engagement and separation between the active friction plate and the driven friction plate. Generally, the clutch During the driving process of the vehicle, frequent operations are required to achieve effective control of the vehicle. Therefore, the operating frequency of the clutch ...

The clutch is a common part in mechanical transmission, which can separate or engage the transmission system at any time. At present, the clutches used in vehicles mostly adopt a friction structure, and the clutch transmission is realized through the engagement and separation between the active friction plate and the driven friction plate. Generally, the clutch During the driving process of the vehicle, frequent operations are required to achieve effective control of the vehicle. Therefore, the operating frequency of the clutch is extremely high, resulting in serious wear of the friction plate, frequent maintenance, and short service life. However, it is difficult to replace and install the friction plate. higher cost
