Description
Technical field
The present invention relates to brake device for car, be specifically related to a kind of hand braking strength booster of hydraulic type automobile。
Background technology
The hand brake device that existing automobile commonly 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 limitation or operator applies the impact of the factors such as strength is not enough, the brake force of its generation is less, and parking strength tends not to reach safety detection and requires to cause potential safety hazard。
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, brake steady, safe and reliable, the hand braking strength booster of hydraulic type automobile of long service life。
For solving above-mentioned technical problem, the hand braking strength booster of hydraulic type automobile of the present invention, including drive end bearing bracket, rear end cap, the cylinder blanket being fixedly installed between described drive end bearing bracket and rear end cap, described cylinder blanket is built-in with back-moving spring near one end of drive end bearing bracket；Described cylinder blanket stage casing is built-in with the cylinder body being fixedly installed by corresponding oil cylinder fixed mount, 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 the big piston of correspondence, described small oil tank is provided with corresponding valve piston, and described large tank and small oil tank are interconnected；Described oil cylinder fixed mount 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 be provided with correspondence front tension bar connection dish and before being fixedly installed on the front tension bar connection dish of drive end bearing bracket side bracing wire connecting rod, described front bracing wire connecting rod is placed in the middle and extension is in drive end bearing bracket；Described back stay two ends are provided with the back stay connection dish of correspondence and are being fixedly installed back guy connecting rod on the back stay connection dish of rear end cap side, described back guy connecting rod is placed in the middle and extension is in rear end cap, and the front tension bar connection dish of described correspondence is connected dish and is crisscross arranged and front tension bar is movable through the back stay connection dish of drive end bearing bracket side, back stay activity through the front tension bar connection dish of rear end cap side with back stay。Time hand braking, external drag-line pulls front bracing wire connecting rod, front bracing wire connecting rod drives corresponding front tension bar connection dish and front tension bar synchronous shift, the front tension bar connection dish that while displacement, rear end cap side is arranged promotes valve piston to move and the hydraulic oil in small oil tank is produced pressure, hydraulic oil promotes big piston at large tank intrinsic displacement again, according to liquid transfer pressure principle, can obtain beyond the Great Wall times over the thrust on valve piston at Radix Angelicae Dahuricae (Radix Heraclei Scabridi)。Driving back stay connection dish and the back stay synchronous shift of correspondence after big piston displacement, the back stay near rear end cap side connects the dynamic back guy connecting rod of dribbling and bounces back and drive wheel cylinder operation thus completing parking action。The valve piston of the present invention inserts in the small oil tank of cylinder body, inserts Radix Angelicae Dahuricae (Radix Heraclei Scabridi) plug in the large tank of described cylinder body, and hydraulic drive completes in the cylinder blanket that drive end bearing bracket and rear end cap are closed。The present invention achieves the amplification of automobile hand brake strength by the principle of liquid transfer pressure, it is ensured that the reliability of automobile hand brake action。
Further, described oil cylinder fixed mount is fixed in cylinder blanket by some bracket fixing bolts, and it facilitates operator to keep in repair adjustment, improves working performance。
Present configuration is simple, easy to operate, stable, reliable, can significantly extend the service life of automobile hand brake, improves traffic safety。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention。
Detailed description of the invention
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, including drive end bearing bracket 16, rear end cap 17, the cylinder blanket 1 being fixedly installed between described drive end bearing bracket 16 and rear end cap 17, described cylinder blanket 1 is built-in with back-moving spring 9 near one end of drive end bearing bracket 16；Described cylinder blanket 1 stage casing is built-in with the cylinder body 2 being fixedly installed by corresponding oil cylinder fixed mount 12, described cylinder body 2 one end is provided with large tank 3, the other end is provided with small oil tank 4, described large tank 3 is provided with the big piston 5 of correspondence, described small oil tank 4 is provided with corresponding valve piston 6, and described large tank 3 is interconnected with small oil tank 4；Described oil cylinder fixed mount 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 be provided with correspondence front tension bar connection dish 10 and before being fixedly installed on the front tension bar connection dish 10 of drive end bearing bracket 16 side bracing wire connecting rod 14, described front bracing wire connecting rod 14 is placed in the middle and extension is in drive end bearing bracket 16；Described back stay 8 two ends are provided with the back stay connection dish 11 of correspondence and are being fixedly installed back guy connecting rod 15 on the back stay connection dish 11 of rear end cap 17 side, described back guy connecting rod 15 is placed in the middle and extension is in rear end cap 17, and the front tension bar connection dish of described correspondence 10 is connected dish 11 and is crisscross arranged and front tension bar 7 activity is through the back stay connection dish 11 of drive end bearing bracket 16 side, back stay 8 activity through the front tension bar connection dish 10 of rear end cap 17 side with back stay。
Described oil cylinder fixed mount 12 is fixed in cylinder blanket 1 by some bracket fixing bolts 13。
During operation of the present invention, external drag-line drives front bracing wire connecting rod 14 displacement to drive front tension bar connection dish 10 and front tension bar 7 synchronous shift of connected correspondence simultaneously, displacement drives valve piston 6 at small oil tank 4 intrinsic displacement near the front tension bar connection dish 10 of rear end cap 17 side simultaneously, the pressure conduction extremely big piston 5 that hydraulic oil is applied by valve piston 6, big piston 5 drives back stay connection dish 11 and back stay 8 synchronous shift of correspondence while large tank 3 intrinsic displacement, back stay connection dish 11 near rear end cap 17 side drives connected back guy connecting rod 15 to bounce back again, retraction drives connected wheel cylinder to complete hand braking operation simultaneously。When vehicle is advanced, before pine, back-moving spring 9 drives back guy connecting rod 15 to reset after bracing wire connecting rod 14, hand braking disables。
