Brake master cylinder is the core component in the brake system of car, to the performance of automobile particularly Security play crucial effects.Existing brake master cylinder is the compensation cellular type mostly; Open and close compensate opening through piston moving in cylinder body; But this brake master cylinder makes the piston cup wearing and tearing very fast owing to hydraulic pressure constantly changes when ABS moves, and influences working life, and it is unreliable to cause braking when serious.
Summary of the invention
Cause braking insecure deficiency for the brake master cylinder leather cup quick abrasion that overcomes existing compensation cellular type; The utility model provides a kind of brake master cylinder of vehicle stabilization controlling type, and that the brake master cylinder of this vehicle stabilization controlling type has is simple in structure, the braking reliable, the characteristics of long service life.
The technological scheme of the utility model is: a kind of brake master cylinder of vehicle stabilization controlling type; Comprise Master cylinder body; Described Master cylinder body is built-in with primary piston assembly and second piston assembly, and second piston assembly left end is connected with two-level spring through the two-level spring seat, and the inside of described two-level spring seat is equipped with the secondary center valve; Described Master cylinder body is internally connected with the locating stud of vertical and Master cylinder body axis, and described locating stud is positioned at the right-hand member of secondary center valve;
Be connected with elementary spring seat between described primary piston assembly and the second piston assembly, elementary spring seat outside is equipped with elementary spring, and the inside of described elementary spring seat is equipped with the primary center valve;
Described primary center valve and secondary center valve include spool, interstage sleeve, spring, spring seat, valve seat, centre valve seal ring; Described primary center valve and secondary center valve all place in its corresponding spring seat through the centre valve seal ring; Described centre valve seal ring is built-in with valve seat; Valve seat inside is provided with spool, and is equipped with the interstage sleeve of band cross through hole between the two, and the longitudinal section of described spool is a T shape; Its transverse axis outside is provided with spring, and described both ends of the spring is separately fixed on interstage sleeve and the spring seat.
Be equipped with vaccum seal ring and pad between described primary piston assembly and the Master cylinder body.
The utlity model has following beneficial effect: owing to take such scheme, during braking, push rod promotes piston advances forward, and primary center valve and secondary center valve move with respect to piston and valve body under the effect of spring backward, make valve closing, produce hydraulic pressure.Signal along with wheel speed sensors under the ABS effect is constantly adjusted hydraulic pressure, in case the car locking has solved compensation cellular type brake master cylinder hydraulic pressure when sufficient ABS moves and constantly changed and make the leather cup wear problems, has prolonged the life-span of brake master cylinder.Simultaneously bigger valve port discharge value is provided under the condition that does not increase stroke, has shortened period of braking, improved the reliability of braking.
