Abstract

The invention discloses discloses a clutch master cylinder assembly and a vehicle. The clutch master cylinder assembly comprises a pump body and a push rod; a cavity is formed in the pump body; a piston is arranged in the cavity; the outer side of the piston abuts against the push rod; the inner side of the piston can slide along the cavity under pushing of the push rod; a compression rod and a spring are arranged on the inner side of the piston; the compression rod is sleeved with the spring; a leather ring is arranged at the connecting position of the compression rod and the piston in a sleeved mode; a lining is further arranged in the cavity; the outer side wall of the lining is attached to the inner wall of the pump body; and the inner side wall of the lining is matched with the leather ring. The structural design of variable cylinder diameter and sectional area is adopted; a variable lever ratio can be provided for the system in the whole stroke process; the maximum control force of a pedal can be reduced through reasonable matching; besides, the lining is additionally arranged in the pump body of a clutch master pump, so that the leather ring and the lining are in contact sliding, and abrasion and abnormal sound are reduced; for vehicle types with large pedal force, the pedal force can be reduced to a certain extent; and the operation comfort of a driver is improved.

Description

technical field [0001] The invention relates to the technical field of automobile clutches, in particular to a clutch master cylinder assembly and a vehicle. Background technique [0002] The clutch master cylinder assembly is the part that is connected to the clutch pedal and connected to the clutch slave cylinder or clutch booster through the oil pipe. , the function is a component used in the hydraulic clutch control system to convert the mechanical force of the human-operated clutch pedal into hydraulic pressure. [0003] The design task of clutch control is to design a suitable "clutch control lever ratio" to meet the pedal force requirement. The bore of the existing clutch master cylinder is usually designed with a fixed cross-section. Due to the characteristics of ordinary diaphragm spring clutches, the separation force is a changing curve, and the corresponding pedal force is also such a changing curve. At the highest point, the pedal force is relatively Larger, so...
