Vehicle hydraulic clutch assembly

Abstract

The invention discloses a vehicle hydraulic clutch assembly. The vehicle hydraulic clutch assembly comprises a box, a driven shaft arranged in the box, a release bearing sleeving the driven shaft, anda release fork cooperating with the release bearing. The vehicle hydraulic clutch assembly further comprises a hydraulic pump mounted on the box; a hydraulic push rod of the hydraulic pump is parallel to the driven shaft; and a free end of the hydraulic push rod is in cooperation transmission with a power end of the release fork. The vehicle hydraulic clutch assembly uses the hydraulic push rod for pushing the release fork to drive the release bearing to move to an engine power source to press a clutch pressure plate separation finger; after a certain displacement, a driven plate and a clutchpressure plate are changed from a pressing state to a separation state; the power source is cut off to realize gear shifting conditions of a transmission; by dint of characteristics of a hydraulic system, the overall vehicle arrangement difficulty is solved; and the clutching force is low, the user operation intensity is low, and meanwhile, a gap between the release bearing and the clutch pressure plate can be eliminated, so that the maintenance requirement of a mechanical clutching mechanism needing to timely adjust a clutching gap is prevented.

Description

technical field [0001] The invention relates to a clutch assembly, in particular to an automobile hydraulic clutch assembly. Background technique [0002] In the existing mechanical clutch mechanism, the mechanical external force pulls the clutch release fork through the clutch cable to drive the release bearing to move to the engine power source. After eliminating the gap between the release bearing and the clutch pressure plate, it continues to move and press the clutch pressure plate. The driven plate and the clutch pressure plate change from the pressed state to the separated state, and the power is cut off to realize the gear shifting conditions of the mechanical transmission. However, in the layout of the whole vehicle, the mechanical cable is limited in its direction, curvature radius, and overall length. These factors are factors that affect the mechanical efficiency. The conventional design needs to consider the gap between the release bearing and the clutch pressur...

AI Technical Summary

Problems solved by technology

However, in the layout of the whole vehicle, the mechanical cable has limited space in terms of direction, curvature radius, and overall length. These factors all affect the mechanical efficiency. The conventional design needs to consider the gap between the release bearing and the clutch pressure plate (2- 3mm); with the wear and tear of the cable, the mechanical loss will increase, and the phenomenon of large clutch force and short service life of the cable will appear; at the same time, the clutch gap will decrease, and the gap must be adjusted in time after the car is used for a period of time. Improper use will result in half-clutch in the initial state, shortening the life of the friction plate, or incomplete separation within the effective stroke, making it difficult to shift gears and damaging the internal parts of the transmission
