Abstract
The utility model discloses a device for preventing a piston in a brake wheel cylinder from colliding. The device comprises a cylinder body, wherein the cylinder body is provided with an oil nozzle; a radial through hole is arranged in the cylinder body and is internally provided with a left piston and a right piston; the left piston and the right piston are in sliding fit with the hole wall of the radial through hole; a spring is connected between the left piston and the right piston; the inner side surfaces of the left piston and the right piston are respectively provided with a leather bowl; and opening parts of the leather bowls are opposite. The device has the advantages that the structure is simple; and since the inner side surfaces of the pistons are provided with the leather bowls, on one hand, a buffering effect is well achieved, on the other hand, a sealing effect is achieved, the pistons can be prevented from colliding, the wear between the pistons is reduced and the service lives of the pistons are prolonged.
Description
Technical field
The utility model relates to the automotive brake field, is specifically related to a kind of wheel cylinder inner carrier crash device that prevents.
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 inner carrier crash device that prevents, in the inboard of piston leather cup is set, and plays buffer function on the one hand, plays seal action on the other hand, prevents to produce between the piston collision.
The technological scheme of the utility model is following:
A kind of wheel cylinder inner carrier crash device that prevents; Include cylinder body; Described cylinder body is provided with oil nozzle, 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, and is connected with spring between the left and right piston; The inner side surface of left and right piston is respectively equipped with leather cup, and the oral area of said leather cup in opposite directions.
The described wheel cylinder inner carrier crash device that prevents 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 beneficial effect of the utility model:
The utility model is simple in structure, in the inboard of piston leather cup is set, and has played good buffer function on the one hand, has played seal action on the other hand, can prevent to produce collision between the piston, has reduced the wearing and tearing between the piston, has prolonged the working life of piston.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1; A kind of wheel cylinder inner carrier crash device that prevents includes cylinder body 1, and cylinder body 1 is provided with oil nozzle; Be provided with radial direction through hole 6 in the cylinder body 1; Be provided with left and right piston 7,4 in the radial direction through hole 6, the hole wall of left and right piston 7,4 and radial direction through hole 6 is slidingly matched, and left and right piston 7, is connected with spring 2 between 4; The inner side surface of left and right piston 7,4 is respectively equipped with leather cup 3; The oral area of leather cup 3 in opposite directions; When left and right piston 7,4 shrinks when taking place to move in opposite directions fast with spring 2 is violent, utilize leather cup 3 to have certain flexible characteristic and prevent left and right piston 7, produce between 4 and collide.
Further, be positioned on the cylinder body 1 of radial direction through hole 6 both sides and be separately installed with dust-proof cover 5.
Claims (2)
