Description
Technical field
The present invention relates to brake device for car, be specifically related to the hand braking strength booster of a kind of hydraulic type automobile.
Background technique
The hand brake device that existing automobile generally uses mostly adopts mechanical lever to drive bracing wire to drive rear braking wheel cylinder oil cylinder piston to produce parking strength, owing to being subject to mechanical lever size restrictions or operator and applying the impact of the factors such as strength deficiency, the braking force of its generation is less, and parking strength often can not reach safety detection and require to cause potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, brake steady, safe and reliable, the hand braking strength booster of hydraulic type automobile of long service life.
For solving the problems of the technologies described above, the hand braking strength booster of hydraulic type automobile of the present invention, comprises front cover, rear end cover, the cylinder blanket being fixedly installed between described front cover and rear end cover, and described cylinder blanket is built-in with Returnning spring near one end of front cover; Described cylinder blanket stage casing is built-in with the cylinder body being fixedly installed by corresponding oil cylinder fixing frame, described cylinder body one end is provided with large tank, the other end is provided with small oil tank, described large tank is provided with corresponding large piston, described small oil tank and is provided with corresponding small piston, and described large tank and small oil tank are interconnected; Described oil cylinder fixing frame respectively by outer and in be evenly equipped with some front tension bars and back stay with circumference activity, described front tension bar two ends are provided with corresponding front tension bar land and near bracing wire connecting rod before being fixedly installed on the front tension bar land of front cover one side, and the placed in the middle and extension of described front bracing wire connecting rod is in front cover; Described back stay two ends are provided with corresponding back stay land and are being fixedly installed back guy connecting rod near on the back stay land of rear end cover one side, placed in the middle and the extension of described back guy connecting rod is in rear end cover, and the front tension bar land of described correspondence and back stay land are crisscross arranged and the front tension bar land of front tension bar activity through the back stay land of front cover one side, back stay activity through rear end cover one side.When hand braking, external drag-line pulls front bracing wire connecting rod, front bracing wire connecting rod drives corresponding front tension bar land and front tension bar synchronous shift, when displacement, the front tension bar land of rear end cover one side setting promotion small piston moves the hydraulic oil in small oil tank is produced to pressure, hydraulic oil promotes large piston again at large tank intrinsic displacement, according to liquid transfer pressure principle, on large piston, can obtain times over the thrust on small piston.After large piston displacement, drive corresponding back stay land and back stay synchronous shift, thereby drive back guy connecting rod to bounce back and drive wheel cylinder operation to complete parking action near the back stay land of rear end cover one side.Small piston of the present invention inserts in the small oil tank of cylinder body, inserts large piston in the large tank of described cylinder body, and hydraulic transmission completes in the cylinder blanket of front cover and rear end cover sealing.The present invention has realized the amplification of automobile hand brake strength by the principle of liquid transfer pressure, guaranteed the reliability of automobile hand brake action.
Further, described oil cylinder fixing frame is fixed in cylinder blanket by some bracket fixing bolts, and its easy-to-operat personnel keep in repair adjustment, improves operating efficiency.
The present invention is simple in structure, easy to operate, stable, reliable, can significantly extend the working life of automobile hand brake, improves traffic safety.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, the hand braking strength booster of hydraulic type automobile of the present invention, comprise front cover 16, rear end cover 17, the cylinder blanket 1 being fixedly installed between described front cover 16 and rear end cover 17, described cylinder blanket 1 is built-in with Returnning spring 9 near one end of front cover 16; Described cylinder blanket 1 stage casing is built-in with the cylinder body 2 being fixedly installed by corresponding oil cylinder fixing frame 12, described cylinder body 2 one end are provided with large tank 3, the other end is provided with small oil tank 4, described large tank 3 is provided with corresponding large piston 5, described small oil tank 4 and is provided with corresponding small piston 6, and described large tank 3 is interconnected with small oil tank 4; Described oil cylinder fixing frame 12 respectively by outer and in be evenly equipped with some front tension bars 7 and back stay 8 with circumference activity, described front tension bar 7 two ends are provided with corresponding front tension bar land 10 and near bracing wire connecting rod 14 before being fixedly installed on the front tension bar land 10 of front cover 16 1 sides, and the placed in the middle and extension of described front bracing wire connecting rod 14 is in front cover 16; Described back stay 8 two ends are provided with corresponding back stay land 11 and are being fixedly installed back guy connecting rod 15 near on the back stay land 11 of rear end cover 17 1 sides, placed in the middle and the extension of described back guy connecting rod 15 is in rear end cover 17, and front tension bar land 10 and the back stay land 11 of described correspondence is crisscross arranged and the front tension bar land 10 of front tension bar 7 activities through the back stay land 11 of front cover 16 1 sides, back stay 8 activities through rear end cover 17 1 sides.
