Abstract

The invention discloses a brake wheel cylinder assembly for preventing the collision between pistons, which comprises a cylinder body, wherein a radial through hole is arranged in the cylinder body; a left piston and a right piston are arranged in the radial through hole and are in sliding fit with the wall of the radial through hole; a spring is connected between the left piston and the right piston; bowl-shaped concave cavities are respectively arranged on the inner lateral surfaces of the left piston and the right piston; port parts of the bowl-shaped concave cavities are opposite to each other; an air tap or an oil nozzle is arranged on the cylinder body; the cylinder body is provided with an opening pore and is screwed with an air bleed screw; and an air bleed cap is arranged at the end part of the air bleed screw. The brake wheel cylinder assembly has the advantages of reasonable structure, small occupied space and favorable sealing performance; and the bowl-shaped concave cavities are arranged at the inner sides of the pistons so as to play a better cushioning action, prevent the collision between the pistons, reduce the wear between the pistons and prolong the service lives of the pistons.

Description

technical field [0001] The invention relates to the field of automobile brakes, in particular to a brake wheel cylinder assembly for preventing piston collision. Background technique [0002] The brake wheel cylinder generally relies on compressed air or oil to enter the brake cylinder and pushes a set of basic devices such as pistons to act as a brake. . [0003] During the working process, if the oil pressure or air pressure in the inner cavity of the brake wheel cylinder changes too much, it will cause the piston inside the brake wheel cylinder to collide during the violent contraction process and be damaged, thus affecting the service life. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a brake wheel cylinder assembly for preventing the collision of the pistons, and a bowl-shaped cavity is provided inside the piston to play a buffering effect to prevent the collision between the pistons. [0005] The technical scheme of the p...
