Abstract

The invention relates to an automobile clutch operation system and a cylinder diameter variable clutch working cylinder thereof. The cylinder diameter variable clutch working cylinder comprises a working cylinder body. The internal cross sectional area of the working cylinder body can be changed. When disengagement force of a clutch is maximum, the sealing cross sectional area, matched with a piston, of the interior of the working cylinder body is maximum, so that the hydraulic lever ratio of the working cylinder is increased to achieve the effect of reducing the pedal force. An annular grooveI and an annular groove II are additionally formed in the inner wall of the working cylinder body. The annular groove II is located on the side, close to an oil inlet of the working cylinder, of theannular groove I. A leather cup I and a leather cup II are arranged on the piston. The cylinder diameter variable clutch working cylinder is simple in structure, low in cost and good in usage effect.The pedal force can be reduced just through change of the inner diameter of the working cylinder. The requirement for driving comfort is met.

Description

technical field [0001] The invention belongs to the technical field of parts and components development of an automobile clutch operating system, and in particular relates to an automobile clutch operating system and a variable cylinder diameter clutch working cylinder thereof. Background technique [0002] The calculation formula of the pedal force is as follows. In the traditional clutch control system, once the pedal lever ratio, release fork lever ratio, efficiency, and pedal assist are determined, since the bore of the clutch working cylinder remains unchanged, the hydraulic lever ratio is also determined. However, the clutch disengagement force changes in time with the disengagement stroke, which leads to a large pedal force when the pedal is stepped on to a certain position, which affects the driving comfort. [0003] Contents of the invention [0004] The invention designs an automobile clutch operating system and its variable-bore clutch working cylinder, which...
