Abstract
The utility model discloses an automobile wheel cylinder assembly which comprises a cylinder body. A left piston and a right piston are arranged in the operation cavity of the cylinder body; leather rings are formed at end parts of the two pistons; opposite grooves are respectively formed on the leather rings of the two pistons; a spring is cushioned between the grooves; shields are installed outside the two pistons and clamped with the cylinder body; and an oil inlet and an air outlet are formed on the cylinder body. The automobile wheel cylinder assembly has simple structure, solves the problems that the pistons are stuck in the operation cavity of a wheel cylinder in an automobile brake system, the guide performance of a leather cup is poor, oil leaks due to the fact that the sealing performance of the cylinder wheel is poor and the like, and has the characteristics of low cost, long service life and the like.
Description
Technical field:
The utility model relates generally to a kind of brake system of car, relates in particular to a kind of automobile wheel cylinder assembly.
Background technique:
At present, in brake system of car, usually adopt the wheel cylinder of hydraulic type, generally comprise the spring between wheel cylinder, piston, leather cup and the leather cup, but be split-type design between traditional piston and the leather cup, the two is not designed to one, only by the spring force effect between the leather cup, motion is close together, piston is stuck in the cylinder body active chamber easily, the steering capability of leather cup is poor, and owing to do not adopt seal approach usually between piston and the cylinder body, and it is poorly sealed and oil leakage phenomenon takes place that wheel cylinder takes place easily.
The model utility content:
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of automobile wheel cylinder assembly is provided, has solved in the brake system of car, piston is stuck in the wheel cylinder active chamber, the steering capability of leather cup is poor, piston and wheel cylinder poor sealing and problems such as leakage of oil occur.
The utility model is achieved through the following technical solutions:
A kind of automobile wheel cylinder assembly, include cylinder body, establish left and right two-piston in the active chamber of described cylinder body, the end of left and right two-piston has leather cup, have groove opposite on the leather cup of left and right two-piston, be equipped with spring between the groove, left and right two-piston is equipped with guard shield outward, guard shield engages with cylinder body, has filler opening, air vent on the cylinder body.
In the described air vent bleed screw is installed, the air vent top is equipped with the venting cap.
In the described filler opening seal ring is housed, the top of filler opening is provided with dust cover.
The utility model has the advantages that:
The utility model is simple in structure, has solved in the brake system of car, and piston is stuck in the wheel cylinder active chamber, and the steering capability of leather cup is poor, and piston and wheel cylinder poor sealing and problems such as leakage of oil occur also have characteristics such as cost is low, long service life simultaneously.
Description of drawings:
Fig. 1 is the utility model structural representation.
