Return device of swing type clutch slave cylinder

Abstract

The invention relates to a return device of a swing type clutch slave cylinder. The return device comprises a piston, swing slip blocks, return springs and a swing rod, wherein an inward concave swing groove in a cone-like shape is formed in the right side of the piston, the bottom of the swing groove is hemispherical, the left end of the swing rod is hemispherical and is in spherical surface fit with the swing groove, a plurality of parallel reset chutes are uniformly and symmetrically formed in the end part of the swing groove, the swing slip blocks are correspondingly mounted in the reset chutes and in single freedom degree fit with the reset chutes, one end of each return spring is movably connected with the corresponding swing slip block, and the other ends of the return springs are movably connected with the swing rod. The return device of the swing type clutch slave cylinder has the advantages of reasonable structural design, low manufacture cost, long service life and the like, the traditional hinge connection is replaced with a swing mode, the service life of the swing rod is prolonged, the swing rod has the return characteristic in a movement process and cannot interfere clutch motion during clutch operation, and the clutch control performance is guaranteed.

Description

technical field [0001] The invention relates to an automobile clutch system, in particular to a centering device of a swing clutch cylinder. Background technique [0002] As we all know, the automobile clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed on the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. 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. Clutch master cylinder and slave cylinder are equivalent to two hydraulic cylinders, the master cylinder has inlet and outlet oil pipes, and the slave cylinder has only one pipe. Step on the clutch, the pressure of the master cylinder is transmitted to the sub-cylinder, the sub-cylinder works, and...

Problems solved by technology

However, the push rod of this design has poor centering performance during use. When the push rod and the external lever plate are pushed, it cannot be reset in time. There is a certain delay, and it is easy to lean against the piston during work. The piston is deflected by force, which affects the movement of the piston and reduces the performance of the clutch
