Description

A kind of W shaped steel wire return spring in caliper

Technical field

The utility model belongs to automotive brake technical field, is related to a kind of W shaped steel wire return bullet in caliper Spring.

Background technique

Requirement of the country to vehicle oil consumption and vehicle exhaust discharge quantity at present is higher and higher, and vehicle factor is forced to require brake Drag it is lower and lower, therefore, the utility model mainly for brake caliper assy increase return spring, be pressurized by return spring The propulsive thrust of generation, optimization brake drag, and then reduce complete-vehicle oil consumption and reduce exhaust emissions.

Utility model content

The purpose of this utility model is and then to propose a kind of W fashioned iron in caliper to reduce sticking of brakes Silk return spring.

The overall technological scheme of the utility model is as follows to achieve the above object:

There are two the first bending part and the second foldings among two the first bending parts for tool in the middle part of the return spring Turn of bilge so that return spring be integrally formed it is W-shaped；The end at the return spring both ends is vertically bent to form folding foot.

Be provided on the medial and lateral brake block backboard of caliper for return spring folding foot insert into aperture.

Return spring is mounted on brake block by the folding foot at both ends, and return spring is in is pressed always under the state Contracting state, by the thrust for the braking release direction that the internal outside hung brake block of return spring generates, optimization brake drags torque.

The return spring is formed by spring steel wire bending.

The return spring is made of metal.

Make polishing fillet processing in the both ends of the return spring.

The beneficial effects of the utility model are:

The utility model generates the thrust in brake release direction by return spring, reduces brake block to the pressure of disk, Reduce brake drags torque, to reduce complete-vehicle oil consumption.

Specific embodiment

With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.

As shown in Figure 1, former 5 main body of return spring is in U-shape, the utility model is arranged at the middle part of the U-shaped of return spring 5 Roll over foot 5a, bending part 5b, 5c.The middle part of return spring 5 formed after bending process three times tool there are two the first bending part 5c and The second bending part 5b among two the first bending part 5c so that return spring 5 be integrally formed it is W-shaped so that reduce rigidity. As shown in figure 3, bending part 5b, 5c and caliper do not contact.

The caliper of the utility model includes bracket 1, brake block circlip 2, piston 8, inboard brake block backboard 7 and outside system Motion block backboard 3, interior outside brake block backboard 7,3 are attached separately to the interior outside of the bracket 1 equipped with brake block circlip 2.

One return spring 5 of each side setting between interior outside hung brake block backboard 7,3 is set in specific implementation, The end at each 5 both ends of return spring is vertically bent to form folding foot 5a.Two return springs in left and right are located at caliper and braking Between block, as shown in Figure 2.

As shown in figure 5, right side aperture 3a and left side aperture 3b is opened on outside hung brake block backboard 3, on inboard brake block backboard 7 Right side aperture 7a and left side aperture 7b is opened, two folding foot 5a of one return spring 5 are inserted into outside hung brake block back respectively In the right side aperture 3a of plate 3 and the right side aperture 7a of inboard brake block backboard 7, two folding foots of another return spring 5 5a is inserted into respectively in the left side aperture 3b of outside hung brake block backboard 3 and the left side aperture 7b of inboard brake block backboard 7.

Aperture on two pieces of brake block backboards is about caliper central axis bilateral symmetry, and return spring 5 is also about in caliper Mandrel line bilateral symmetry.Brake block is mounted on the recess portion on the brake-caliper support equipped with brake block circlip 2, on brake block circlip 2 Slippage slot is constituted, as shown in figure 5, sliding on slippage slot.

As shown in figure 4, when carrying out brake block, inboard brake block 3 and outside hung brake block 7 are to the direction close to brake disc 6 Movement, when braking release, the return spring on brake block can generate the thrust far from brake disc direction.Outside hung brake in this way Block can be dragged by the slippage slot of the brake block circlip 2 on bracket 1 to far from the movement of brake disc direction to reach reduction Purpose.

As shown in figure 4, the utility model can be reduced by increase return spring 5 drags torque, or than comparison tradition Design the utility model brake block rate of release faster.It is dragged to reduce, reduces complete-vehicle oil consumption.

Examples detailed above is the further explanation to the utility model, is not the specific restriction to the utility model, any right Structure after the utility model simple transformation belongs to the protection scope of the utility model.
