Abstract

The invention provides a hydraulic driven cylinder and a hydraulic driven cylinder application assembly. The hydraulic driven cylinder comprises a guide pipe and a cylinder body sleeving he guide pipe, wherein a pressure chamber is formed between the guide pipe and the cylinder body; a piston is accommodated in the pressure chamber and is connected with a release bearing; the bottom of the cylinder body extends outwards so as to form a mounting part; a vibration absorption piece is attached to the bottom of the cylinder body. According to the hydraulic driven cylinder, when axial vibration of an engine is transferred to the hydraulic driven cylinder by virtue of a diaphragm spring of a clutch, the vibration absorption piece absorbs vibration of a hydraulic fluid in the hydraulic driven cylinder, so that pedal vibration caused by vibration is reduced or eliminated and thus the comfort of a driver is enhanced.

Description

technical field [0001] The invention relates to an automobile hydraulic clutch separation system, in particular to a hydraulic slave cylinder and a hydraulic slave cylinder application assembly. Background technique [0002] The clutch is installed between the engine and the transmission. During the whole process of the car from starting to normal running, the driver can manipulate the coupling or disengagement of the clutch according to the needs, so that the engine and the transmission are gradually combined or temporarily separated. The gradual combination of the engine and the transmission can ensure the smooth start of the car; the temporary separation of the engine and the transmission is convenient for shifting, reducing the impact of shifting and preventing overloading of the transmission system such as the transmission. [0003] The hydraulic clutch separation system is used to realize the separation of the clutch. figure 1 is a schematic diagram of the hydraulic ...
