Description

A kind of brake block backboard being used in caliper

Technical field

The utility model belongs to automotive brake technical field, is related to a kind of brake block backboard being used in caliper.

Background technology

Country forces vehicle factor to require brake vehicle oil consumption and the requirement more and more higher of vehicle exhaust discharge quantity at present Weight it is more and more lower, therefore, the utility model is designed mainly for the brake block backboard in brake caliper assy, by Increase bulge-structure on brake block backboard, reduce brake block back plate thickness, reduce brake overall size and weight, make system Dynamic device design is more compact, improves the space of brake.

Utility model content

The purpose of this utility model is to improve the space arrangement of brake in order to reduce caliper weight and overall size, And then propose a kind of brake block backboard being used in caliper.

Overall technological scheme of the present utility model is as follows to achieve the above object：

The utility model includes inboard brake block backboard and outside hung brake block backboard, and interior outside brake block backboard is close to system The end face both sides of the edge of Moving plate are provided with to the recess away from brake disc direction indent, are set in the end face both sides of the edge away from brake disc The convex portion of oriented remote brake disc direction evagination, by the interior outside brake block backboard of the setting of convex portion and recess to away from system Extend extra safe distance in Moving plate direction so that interior outside brake block backboard can design thinner.

The brake block backboard uses punch forming.

The utility model safe thickness can use the smaller backboard of thickness when identical, relative to conventional backing plate caliper in backboard Design profile on thickness direction can be more compact.

The beneficial effects of the utility model are：

Bulge-structure be present on the utility model backboard, when brake block complete wear is damaged, the safe clearance ratio that stays on support It is more without using the backboard of boss, thus in the case of safe clearance identical, can be designed using the backboard of the structure it is thinner, And then the overall size of caliper is reduced, brake weight is reduced, improves the space arrangement of brake.

Embodiment

Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the utility model.

As shown in Fig. 2 the utility model includes inboard brake block backboard 7 and outside hung brake block backboard 3, the inboard brake block back of the body There is friction material 5 plate 7 and the side of outside hung brake block backboard 3, and opposite side is respectively provided with inner side bloop 4 and outside bloop 8, system Motion block backboard is mounted in the interior outside of the support 1 equipped with brake block jump ring 2.Through hole is provided with interior outside brake block backboard 3,7, is rubbed The part of material 5 is wiped to be inlaid in the through hole of interior outside brake block backboard 3,7 and be fixedly connected on interior outside brake block backboard 3,7 End face on.Brake block backboard, bloop and friction material composition brake block, installed in the caliper equipped with brake block jump ring 2 On support, the recess on brake block jump ring 2 forms slippage slot, as shown in figure 5, being slid on slippage slot.

The outside hung brake block backboard 3 of specific implementation is as shown in figure 1, the lower surface of outside hung brake block backboard 3 in figure is close The end face of brake disc 6, the lower surface both sides of outside hung brake block backboard 3 are respectively equipped with recess 3c and outside on the right side of outside hung brake block backboard Recess 3d on the left of brake block backboard.The upper surface of outside hung brake block backboard 3 in figure is the end face away from brake disc 6, outside hung brake The upper surface both sides of block backboard 3 are respectively equipped with convex portion 3a and outside hung brake block backboard left side convex portion 3b on the right side of outside hung brake block backboard.

The structure of inboard brake block backboard 7 and outside hung brake block backboard 3 is symmetrical, specifically in inner side brake block backboard 7 Lower surface both sides are respectively equipped with convex portion 7a and inboard brake block backboard left side convex portion 7b, inboard brake on the right side of inboard brake block backboard The upper surface both sides of block backboard 7 are respectively equipped with recess 7c and inboard brake block backboard left side recess 7d on the right side of inboard brake block backboard.

Inboard brake block backboard is between piston 10 and brake disc 6, outside hung brake block backboard be in caliper 9 hook pawl and Between brake disc 6.

As shown in Figure 4 and Figure 6, when friction material 5 is because of brake wear to inboard brake block backboard 7 and outside hung brake block backboard 3 and when reaching limit of wear state, interior outside brake block backboard is adjacent to brake disc 6, is dropped to ensure that brake block is unlikely, brake block The size that backboard sliding position stays in support slippage slot need to reach certain value, referred to as safe thickness.

As shown in Figure 4 and Figure 6, the utility model can by designing convex portion 3a, 3b, 7a, 7b and recess 3c, 3d, 7c, 7d Increase extra safe distance, or comparison can than traditional brake block backboard backboard of the present utility model as shown in Figure 3 That designs is thinner.In other words it is this practicality in the case of with identical back plate thickness of the utility model and existing traditional structure It is new that there is bigger safe distance；Either the utility model and existing traditional structure are in the case of with identical safe distance The utility model has back plate thickness, it is achieved thereby that saving materials while ensure that wear requirements.

Examples detailed above is to further explanation of the present utility model, is specifically limited of the present utility model, any right Structure after the utility model simple transformation belongs to the scope of protection of the utility model.
