Abstract
The utility model discloses the wear-resistant brake block of a kind of buffering, comprise steel plate, thermal-protective coating and brake pad, brake pad is closely fixed on steel plate by thermal-protective coating; Brake pad comprises buffer layer and friction layer, and buffer layer and thermal-protective coating fit tightly; Friction layer is positioned on buffer layer and fits tightly with buffer layer, and friction layer is that two ends tilt to buffer layer, and protrude to brake disc centre; Outer surface in the middle of friction layer is provided with the projection of a plurality of hollows, and this projection can gradually reduce under pressure until flatten.In the utility model, brake pad arranges buffer structure, and during braking, the area of contact of brake pad upper surface and brake disc increases gradually, the frictional force between brake pad and brake disc is progressively increased, parking gently; When stopping parking when operation, the brake pad brake disc that can speed away under the effect of buffer structure, reduces unnecessary frictional loss, accelerates after vehicle brake the reaction time of speed-raising again.
Description
Technical field
The utility model relates to automobile brake technical field, relates in particular to the wear-resistant brake block of a kind of buffering.
Background technique
In the brake system of automobile, brake block is the breaking piece of most critical.Brake block generally consists of steel plate, bonding thermal-protective coating and brake pad.Wherein, steel plate will come antirust through application; Thermal-protective coating is comprised of adiabatic material; Brake pad is comprised of friction material, tackiness agent, is compressed on brake disc or brake drum and produces friction during brake, and tire and ground produce friction simultaneously, and the kinetic energy that vehicle is advanced converts the heat energy after friction to, thereby reaches the object of vehicle deceleration brake.
In Motor Vehicle Braking Procedure, brake pad upper surface contacts completely with brake disc, can play good braking effect; Yet just close to contact completely, moment will reach maximal friction when brake pad just contacts with brake disc, brake response is very sensitive.Yet sometimes, user, when braking, does not wish just to have started just to produce maximum braking effect, but wishes a mild braking process.
Model utility content
In order to solve the technical problem existing in background technique, the utility model proposes the wear-resistant brake block of a kind of buffering, brake pad arranges buffer structure, the frictional force between brake pad and brake disc is progressively increased, parking gently.
The wear-resistant brake block of a kind of buffering the utility model proposes, comprising: steel plate, thermal-protective coating and brake pad, and brake pad is closely fixed on steel plate by thermal-protective coating; Brake pad comprises: buffer layer, fits tightly with thermal-protective coating; Friction layer, is positioned on buffer layer, fits tightly with buffer layer, and friction layer is that two ends tilt to buffer layer, and protrude to brake disc centre; Outer surface in the middle of friction layer is provided with the projection of a plurality of hollows, and this projection can gradually reduce under pressure until flatten.
Preferably, in the projection of a plurality of hollows, fill padded coaming.
Preferably, between friction layer and buffer layer, be provided with air cavity, friction layer surface offers a plurality of through holes, is communicated with respectively with air cavity, and when when brake, friction layer compresses, the Bas Discharged in air cavity, after brake finishes, recovers at elastic force lower air chamber.
Preferably, the projection of a plurality of hollows is communicated with air cavity.
In the utility model, brake pad arranges buffer structure, and during braking, the area of contact of brake pad upper surface and brake disc increases gradually, the frictional force between brake pad and brake disc is progressively increased, parking gently; When stopping parking when operation, the brake pad brake disc that can speed away under the effect of buffer structure, reduces unnecessary frictional loss, accelerates after vehicle brake the reaction time of speed-raising again.
Accompanying drawing explanation
Fig. 1 is the wear-resistant brake block structure figure of a kind of buffering that the utility model embodiment 1 proposes.
Reference character:
1, steel plate; 2, thermal-protective coating; 3, buffer layer; 4, friction layer; 5, projection; 6, through hole; 7, air cavity.
Embodiment
As shown in Figure 1, the utility model embodiment has proposed the wear-resistant brake block of a kind of buffering, comprising: steel plate 1, thermal-protective coating 2 and brake pad, and brake pad is closely fixed on steel plate 1 by thermal-protective coating 2;
Brake pad comprises buffer layer 3 and friction layer 4; Buffer layer 3 fits tightly with thermal-protective coating 2; Friction layer 4 is positioned on buffer layer 3 and fits tightly with buffer layer 3, and friction layer 4 is that two ends tilt to buffer layer 3, and protrude to brake disc centre.
Projection during car brakeing in the middle of friction layer 4 first contacts with brake disc, start area of contact little, the frictional force producing is also little, can not cause unexpected parking, along with proceeding of brake operating, friction layer 4 is driven plain gradually under radial compression applied, and the area of contact of itself and brake disc increases gradually, frictional force between brake pad and brake disc is progressively increased, parking gently; When stopping parking when operation, the brake pad brake disc that can speed away under the effect of buffer layer, reduces unnecessary frictional loss, accelerates after vehicle brake the reaction time of speed-raising again.
Outer surfaces in the middle of friction layer 4 are provided with the projection 5 of a plurality of hollows, and this projection can gradually reduce under pressure until flatten, and further improves buffer function.In the projection 5 of a plurality of hollows, can fill padded coaming.
Between friction layer 4 and buffer layer 3, be provided with air cavity 7, friction layer 4 surfaces offer a plurality of through holes 6, are communicated with respectively with air cavity 7, when when brake, friction layer 4 compresses, the Bas Discharged in air cavity 7, after brake finishes, at elastic force lower air chamber, recover, reach the effect of accelerating heat radiation.The projection 5 of a plurality of hollows is also communicated with air cavity 7.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and model utility design thereof, be equal to replacement or changed, within all should being encompassed in protection domain of the present utility model.
