Abstract
The utility model discloses a double-oil-taking mechanism of a brake master cylinder. The double-oil-taking mechanism of the brake master cylinder comprises a cylinder body, wherein an axial through hole is formed in the cylinder body, a front piston assembly and a back piston assembly are respectively arranged in the axial through hole, the front piston assembly and the back piston assembly are matched with the hole wall of the axial through hole in a sliding mode, a plug screw is arranged at the front end of the axial through hole in a screwing mode, a dustproof cover is installed at the back end of the axial through hole, springs are connected between the front piston assembly and the back piston assembly, and between the front piston assembly and the plug screw, the cylinder body arranged on one side of the front piston assembly and the back piston assembly is respectively provided with limited bolts in a screwing mode, and two oil filler holes which are communicated with the axial through hole and are provided with dustproof plug are formed at the upper end of the cylinder body. The double-oil-taking mechanism of the brake master cylinder is reasonable in structure, due to the fact that the front piston assembly and the back piston assembly are arranged and are matched with double oil inlets for inletting oil, brake performance is greatly improved, and due to the fact that the front piston assembly and the back piston assembly are in a split type structure, the double-oil-taking mechanism of the brake master cylinder is enabled to be convenient to install and maintain, and has good practical value.
Description
Technical field
The utility model relates to the automotive brake field, is specifically related to a kind of two oil-inlet mechanisms of brake master cylinder.
Background technique
Brake master cylinder generally is comprised of brake cylinder head, piston, piston rod, leather cup and release spring etc., effect by three-way valve, when making pressurized air enter master cylinder, pushing piston plays braking action by a cover base apparatus, it is a part of automotive brake, for generation of the power that hinders vehicle movement or movement tendency, i.e. braking force.
The most more complicated of existing brake master cylinder structure, volume is large, and it is large to take up room, and has brought inconvenience to installation and maintenance; Its inside arranges single piston mostly in addition, and it is not fine causing braking effect.
The model utility content
The purpose of this utility model provides a kind of two oil-inlet mechanisms of brake master cylinder, the two filler opening oil-feeds of double-piston assembly and coupling is set improves braking ability.
The technical solution of the utility model is as follows:
A kind of two oil-inlet mechanisms of brake master cylinder, include cylinder body, it is characterized in that: be provided with axial hole in the described cylinder body, be respectively equipped with forward and backward piston assembly in the described axial hole, the hole wall of described forward and backward piston assembly and axial hole is slidingly matched, the front end of described axial hole has screwed togather plug screw, the rear end of axial hole is equipped with dust-proof cover, be connected with respectively spring between the described forward and backward piston assembly and between secondary piston assembly and the plug screw, be positioned on the cylinder body of forward and backward piston assembly one side and screw togather respectively the limited location screw; The upper end of described cylinder body is respectively equipped with two oil holes that lead to axial hole and is provided with dust plug.
Two oil-inlet mechanisms of described brake master cylinder is characterized in that: be provided with copper packing between the fitting surface of described plug screw and axial hole front end.
Two oil-inlet mechanisms of described brake master cylinder is characterized in that: seal by copper packing between described stop screw and the cylinder body.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, and forward and backward double-piston assembly and the two filler opening oil-feeds of coupling are set, and has greatly improved braking ability, and forward and backward piston assembly is split-type structural, so that installation and maintenance is all very convenient, has good use value.
