Automobile braking master cylinder is the vitals in the brake system of car, and its effect is that the piston through brake master cylinder pushes fluid in the brake cylinder, to realize the braking brake in the running.The brake master cylinder of existing technology is when fluid is exported, and it is spacing that the piston motion in the cylinder body only depends on the cylinder body end wall to carry out, and stroke is long when causing piston motion can't in time reset, and influences the oil transportation efficient of brake master cylinder.
The model utility content
The utility model purpose provides a kind of brake master cylinder assy, and brake master cylinder piston moves near the spacing problem that can't in time reset of cylinder body end wall in the existing technology to solve.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of brake master cylinder assy includes the cylinder body of cross setting, and said cylinder body has horizontal inner chamber; The cylinder body top is provided with the vertical filler opening of central shaft that two-way is communicated with inner chamber of cylinder block, and cylinder body left end upper angled is provided with the oil outlet that is communicated with inner chamber of cylinder block, it is characterized in that: said inner chamber of cylinder block left part is slidingly fitted with secondary piston; The inner chamber of cylinder block right part is slidingly fitted with back piston, and the left end of said forward and backward piston is separately installed with the identical valve seat of structure, and said valve seat has inner chamber; Valve base cavity constitutes by left and right that combines through step; And the valve base cavity left part has the accent that is positioned on the valve seat side, and the valve seat outer wall forms the ring platform, is slidingly fitted with the valve leather circle in the said valve base cavity left part; The spool that can stop up step place between left and right of the valve base cavity is installed in the valve leather circle; In the said valve base cavity left part accent circlip is installed, is connected with valve spring between said valve leather circle and the circlip, said secondary piston right-hand member is equipped with spring seat; The rear spring right-hand member is equipped with spring support; Be connected with front spring between the ring platform of said secondary piston valve seat outer wall and the cylinder body left end, be connected with rear spring between the ring platform of secondary piston spring seat and rear spring valve seat outer wall, also be respectively arranged with position limit pin near the filler opening position in the said cylinder body; Said position limit pin upper end is connected to the cylinder body top, and the position limit pin lower end is connected to cylinder base.
Described a kind of brake master cylinder assy is characterized in that: said filler opening top is equipped with the oil-feed seal ring, in the said oil-feed seal ring dust plug is installed.
The utility model is simple in structure, is easy to realize.In cylinder body, be provided with forward and backward piston; The left end of forward and backward piston all is equipped with valve seat, between near the cylinder body top of filler opening, side walls, is connected with position limit pin respectively, during current, back piston motion; Replace on the valve seat of forward and backward piston through position limit pin; Can carry out spacingly timely and effectively to forward and backward piston motion, guarantee in time to reset after the forward and backward piston motion, and then can effectively guarantee the oil transportation efficient of brake master cylinder.
