Description

A kind of Brake for vehicle with parking function

Technical field

The utility model relates to a kind of drg that is used for two-wheeled motor vehicle with parking function.

Background technology

During the two-wheeled motor vehicle Parking; The general side stand that adopts puts down and Parking, and this Parking mode can be applicable to the level land Parking well, yet; When the Parking of this kind mode is suitable for the slope Parking; The front-wheel of motor bike can be rotated further along the slope, makes the motor bike lack of equilibrium and topples over, thereby damage motor bike.

For solving slope Parking problem; The utility model patent that occurs the preceding disc brake lockout mechanism of a kind of two-wheeled motor vehicle in the prior art; The patent No. of this patent is " 200420033657.X ", and referring to Fig. 1, it comprises the pump housing 10, stay bearing plate 30, handle bearing 40 and the locating piece 50 that handle 20 is installed; Stay bearing plate 30 1 ends are fixedly connected on the handle bearing 40 of the pump housing 10; Latch combination 60 of other end captive joint; Locating piece 50 bolt togethers with bayonet on stay bearing plate 30, torsion spring set on bolt and an end be connected with locating piece 50, the other end is connected with stay bearing plate 30.

When the Parking of motor bike slope, the handle 20 of holding with a firm grip makes front-wheel be in braking state; Then latch combination 60 is pressed downwards; Its lower end is stretched out block handle 20 and restriction handle 20 resets, the bayonet socket of locating piece 50 blocks latch combination 60 and makes its location, realizes the slope Parking.

Yet, disc brake lockout mechanism before the two-wheeled motor vehicle of the prior art, its bayonet socket through locating piece 50 blocks latch combination 60, makes latch make up 60 lower ends and stretches out and block handle 20 and restriction handle 20 resets.Therefore, it has following defective:

One, on the locating piece 50 bayonet socket is set, therefore, the intensity of locating piece 50 weakens greatly, and in use, the bayonet socket of locating piece 50 is very easy to fracture;

Two, be installing and locating piece 50, also stay bearing plate 30 need be set on handle bearing 40, so must make this brake structure become complicated, and influence the intensity of this brake structure, and influence the attractive in appearance of this brake structure.

Seeing that the drg of the tool parking function of prior art has above-mentioned defective, the inventor develops a kind of Brake for vehicle that overcomes the tool parking function of above-mentioned defective, and this case produces thus.

The utility model content

The purpose of the utility model is to provide a kind of simple in structure and Brake for vehicle with parking function that intensity is good.

For reaching above-mentioned purpose, the solution of the utility model is:

A kind of Brake for vehicle with parking function comprises the pump housing, handle, piston, spring, block and retracing spring; Handle is articulated on the pump housing, and block is articulated on the handle, in the articulated section of block and handle retracing spring is set, and first step is set on the block, and setting cooperates the second step that makes handle spacing on the pump housing with first step; Form cavity in the pump housing, piston places cavity, and piston one end is against spring, and the other end is against handle.

Further, retracing spring is a torsion spring, and torsion spring one end is against block, and the other end is against handle.

Further, block is a cross-sectional plane cylinder triangular in shape, and wherein the incline place of adjacent side forms profile groove, and upper bottom surface is to being provided with perforation by profile groove, and bottom surface is provided with blind hole to boring a hole; Be provided with on the handle and the cooresponding pivoted hole of perforation, the pivoted hole of handle is partially submerged in this profile groove, and the block pin passes perforation, pivoted hole successively and inserts blind hole, and block is articulated on the handle.

Further, braking signal switch is set also in the pump housing, braking signal switch one end is connected with brake circuit, and the other end and handle lean.

After adopting such scheme; When the Parking of needs slope, hold handle, then the first step that is provided with on the block is resisted against the second step on the pump housing; Decontrol handle then; By the antagonistic force that is arranged on piston in the pump housing, with first step and second step tightly against and make handle spacing, and be in braking state.

Therefore, the utility model is to realize parking function by the second step on the block that is articulated in handle and the pump housing, and it has following having a few:

One, the utility model articulates a block and realizes parking function, need not the same too much member that is provided with prior art patent, can save the mounting hole of many installation components, thereby be unlikely to too to weaken the intensity of brake structure;

Two, the utility model only increases by a block in the prior art, and therefore, it is simple in structure, and does not affect the appearance;

Three, the utility model only needs block and second step against just realizing parking function, and is very easy to use.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done detailed explanation.

Consult Fig. 2 to Fig. 5, a kind of Brake for vehicle with parking function that the utility model discloses comprises the pump housing 1, handle 2, piston 3, spring 4, block 5 and retracing spring.

Handle 2 is articulated on the pump housing 1, can articulate through bolt and cooperating of nut, also can otherwise articulate.

Block 5 is articulated on the handle 2, in the articulated section of block 5 and handle 2 retracing spring is set, and retracing spring is preferably torsion spring 6, and torsion spring 6 one ends are against block 5, and the other end is against handle 2, and retracing spring also can be other form; First step 51 is set on the block 5, second step 11 is set on the pump housing 1, second step 11 cooperates with first step 51 makes handle 2 spacing, thereby makes handle 2 be in braking state.

Form cavity 12 in the pump housing 1, piston 3 places cavity 12, and piston 3 one ends are against spring 4, and the other end is against handle 2.

Be to improve the intensity of block 5, block 5 can be set to cross-sectional plane cylinder triangular in shape, and wherein the incline place of an adjacent side forms profile groove 52, and upper bottom surface be to should being provided with perforation 53 by profile groove 52, and bottom surface 53 is provided with blind hole 54 to boring a hole; Be provided with on the handle 2 and perforation 53 cooresponding pivoted holes 21, pivoted hole 21 positions of handle 2 embed in this profile groove 52, and block pin 7 passes perforation 53, pivoted hole 21 successively and inserts blind hole 54, and block 5 is articulated on the handle 2.

The utlity model has the brake prompting function for making, in the pump housing 1 braking signal switch 8 can also be set, braking signal switch 8 one ends are connected with the brake circuit (not shown), and the other end and handle 2 lean.

During use, when two-wheeled motor vehicle need be on the slope during Parking, the handle 2 of holding with a firm grip; The first step 51 of block 5 is snapped in the second step 11 of the pump housing 1; Release handle 2 then, piston 3 under the effect of spring 4 and hydraulic pressure, ejection handle 2; With first step 51 and second step 11 tightly against and make handle 2 spacing, and be in braking state; When needs were removed brake, promptly handle 2 was pushed block 5 aside, first step 51 and second step was opened in 11 minutes, thereby handle 2 is resetted, and removed braking state.

The embodiment that the above is merely the utility model is not to this case design-calculated restriction, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
