Abstract
The utility model discloses a brake wheel cylinder assembly with piston protection devices, which comprises a cylinder body. A radial through hole is arranged in the cylinder body. Left and right pistons are arranged in the radial through hole. The left and right pistons are in slide fit with the hole wall of the radial through hole. A spring is connected between the left and right pistons. The rear ends of the left and right pistons are respectively provided with elastic rubber blocks. The cylinder body is provided with an air tap communicated to the radial through hole. The cylinder body is provided with an air outlet and is screwed with a bleed screw. The end part of the bleed screw is provided with a bleed cap. The brake wheel cylinder assembly has a simple structure and a light weight, occupies small space and has good sealing performance. The elastic rubber blocks are arranged inside the pistons and take a good buffering effect, so that the collision is prevented from being generated between the pistons, the wear between the pistons is reduced and the service life of the pistons is prolonged.
Description
Technical field
The utility model relates to the automotive brake field, is specifically related to a kind of wheel cylinder assembly that has the piston protective gear.
Background technique
Wheel cylinder generally relies on pressurized air or oil to get into master cylinder, and promotion piston etc. overlap base apparatus and play braking action, are parts of automotive brake, are used to produce the power that hinders vehicle movement or movement tendency, i.e. braking force.
In the working procedure,, will cause the inner piston of wheel cylinder in violent contraction process, to bump, be damaged, thereby influence working life if the oil pressure of wheel cylinder inner chamber or pressure change are excessive.
The model utility content
The purpose of the utility model provides a kind of wheel cylinder assembly that has the piston protective gear, in the inboard of piston elastic block rubber is set, and plays buffer function, prevents to produce between the piston collision.
The technological scheme of the utility model is following:
A kind of wheel cylinder assembly that has the piston protective gear; Include cylinder body; It is characterized in that: be provided with radial direction through hole in the said cylinder body, be provided with left and right piston in the described radial direction through hole, the hole wall of described left and right piston and radial direction through hole is slidingly matched; Be connected with spring between the left and right piston, the rear end of left and right piston is respectively equipped with elastic block rubber; Described cylinder body is provided with the valve that leads to radial direction through hole, and cylinder body is provided with the air outlet and screws togather bleed screw, and the end of said bleed screw has the venting cap.
The described wheel cylinder assembly that has the piston protective gear is characterized in that: be positioned on the cylinder body of said radial direction through hole both sides and be separately installed with dust-proof cover.
The described wheel cylinder assembly that has the piston protective gear is characterized in that: be respectively equipped with seal ring between the hole wall of described left and right piston and radial direction through hole.
The beneficial effect of the utility model:
The utility model is simple in structure, and is in light weight, and it is little to take up room; Good seal performance is provided with elastic block rubber in the inboard of piston, has played good buffer function; Prevent to produce collision between the piston, reduced the wearing and tearing between the piston, prolonged the working life of piston.
