Abstract
The utility model discloses a rear brake cylinder assembly, which comprises a cylinder body, wherein a cylindrical oil chamber is formed in the cylinder body; and a mounting end with a protrusion is arranged on one side of the cylinder body, and an oil inlet hole and a vent hole which are communicated with the oil chamber are formed in the mounting end. According to the rear brake cylinder assembly, a protective cover is arranged at the upper end of a piston, and a sealing leather collar is arranged on the side of the piston, so that dust and air can be effectively prevented from entering the oil chamber, and problems are not produced when a wheel cylinder is used for long time.
Description
Technical field
The utility model relates to brake pump field behind the automobile, relates in particular to a kind of rear braking subpump assembly.
Background technique
Rear braking subpump is the important composition parts of brake device for car, is usually located in the automobile rear brake, steps on brake back master cylinder and produces thrust hydraulic oil is overwhelmed brake cylinder, and the inner piston of wheel cylinder receives hydraulic coupling and begins to move brake block is promoted.Contain brake oil in the brake cylinder, and oil outlet and filler opening are arranged.When touching on the brake, oil outlet is opened, and filler opening is closed.Under the pressure of pump housing piston, brake oil pipe is extruded oil pipe and makes braking function to each wheel cylinder diffluence.When the releasing of brake plate.Oil outlet in the general braking pump can be closed, and filler opening is opened, and brake oil is back in the general braking pump from each wheel cylinder, gets back to reset condition.
The model utility content
In order to solve the problems of the prior art, the utility model provides a kind of rear braking subpump assembly, and is easy to use, simple in structure, the working procedure good stability, and long-term use is not fragile.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is following:
A kind of rear braking subpump assembly comprises cylinder body, and described cylinder interior has columniform grease chamber; Described cylinder body one side has protruding mounting end, offers the oil inlet hole and the vent hole that communicate with the grease chamber in the mounting end.
Offer the groove of circular arc on the sidewall of described cylinder body.
The utility model is through installing protective housing in the piston upper end; And, can prevent effectively that dust and air from getting into the grease chamber at piston side installation sealing apron, guaranteed that long-time use of wheel cylinder can not go wrong yet; The working procedure good stability, long-term use is not fragile.
