Abstract
The utility model discloses a wheel cylinder assembly, which comprises a cylinder body. A circular boss is arranged at the upper end of the cylinder body, a left piston and a right piston are arranged in an operating cavity of the cylinder body, leather cups are arranged at the ends of the left piston and the right piston, opposite spring mounting holes are respectively disposed on the leather cups of the left piston and the right piston, a spring is arranged between the spring mounting holes in a cushioned manner, and protecting covers are mounted on the outer sides of the left piston and the right piston and clamped with the cylinder body. The wheel cylinder assembly is simple in structure, and solves the problems that in an automatic brake system, pistons are jammed in an operating cavity of a wheel cylinder, guidance performances of leather cups are poor, the wheel cylinder is poor in sealing performance to cause oil leakage, and the like. The wheel cylinder assembly further has the advantages 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 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 effect of the spring side 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 wheel cylinder assembly to be provided, 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, 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 wheel cylinder assembly, include cylinder body, the upper end of cylinder body has the boss platform, 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, has relative spring mounting hole on the leather cup of left and right two-piston, is equipped with spring between the spring mounting hole, left and right two-piston is equipped with guard shield outward, and guard shield engages with cylinder body.
Have the air vent that communicates with active chamber on the described cylinder body, bleed screw is installed on the air vent.
Have filler opening on the described cylinder body, seal ring is housed in the filler opening, 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:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Referring to accompanying drawing, a kind of wheel cylinder assembly, include cylinder body 1, the upper end of cylinder body 1 has boss platform 2, establish a left side in the active chamber of cylinder body 2, right two- piston 3,4, a left side, the end of right two-piston has leather cup 5, a left side, have relative spring mounting hole 6 on the leather cup of right two-piston, be equipped with spring 7 between the spring mounting hole, a left side, right two-piston is equipped with guard shield 8 outward, guard shield engages with cylinder body, have the air vent that communicates with active chamber on the cylinder body, bleed screw is installed on the air vent, have filler opening on the cylinder body, seal ring is housed in the filler opening, and the top of filler opening is provided with dust cover.
