Abstract
The utility model discloses a brake pad with dust discharging grooves, which comprises a brake pad body formed by a steel pad and a friction material layer pressed at high temperature and mutually attached. A plurality of dust discharging grooves are longitudinally arranged on and vertically penetrate through the end surface of the friction material layer opposite to a brake disk, and bilaterally and symmetrically arranged with the middle of the friction material layer serving as a central line. Since the dust discharging grooves are arranged on the end surface of the friction material layer opposite to the brake disk, the friction dust generated from mutual loss of the friction material layer and the brake disk in friction, the dust cannot be accumulated, smoothness of the friction surfaces is guaranteed, frictional factor of the brake pad can be stabled, and friction noise caused by unsmooth friction surfaces can be eliminated.
Description
Technical field
The utility model relates to a kind of automobile brake block, is specifically related to a kind of brake block with the dust discharge groove.
Background technique
Automobile is mainly fitted mutually by the high temperature compacting by steel disc and friction material layer with brake block and is constituted, in the braking automobile process, friction material layer and brake disc mutual friction mutually, generation makes the power of automobile brake, because friction material layer is made by dusty material usually, so the mutual loss of meeting when rubbing when friction material layer and brake disc produces certain friction dust, the noise when the long-term accumulation meeting causes rubbing surface out-of-flatness, friction factor instability to increase friction then etc.
Summary of the invention
At the deficiencies in the prior art, the utility model provides that a kind of rubbing surface is smooth, stable friction factor and the low band dust discharge groove brake block of friction noise.
For achieving the above object, the utility model provides a kind of brake block with the dust discharge groove, comprise the brake block body, described brake block body is fitted mutually by the high temperature compacting by steel disc and friction material layer and is constituted, and described friction material layer and brake disc end face in opposite directions is provided with the dust discharge groove.
The utility model can further be set to described dust discharge groove and vertically be arranged on friction material layer and the brake disc end face in opposite directions and run through up and down.
The utility model also can further be set to described dust discharge groove and be some, and is that center line is symmetrical set with the neutral position of friction material layer.
The beneficial effects of the utility model are: owing to set up the dust discharge groove on friction material layer and brake disc end face in opposite directions, so friction material layer and the brake disc friction dust that mutual loss is produced when friction can be discharged timely and effectively, dust can't be accumulated, guaranteed the smooth of rubbing surface, also stablize the friction factor of brake block, eliminated the friction noise that is brought because of the rubbing surface out-of-flatness.
The utility model can be set to further also that the left and right sides is provided with chamfering on described friction material layer and the brake disc end face in opposite directions.
Adopt said structure, make the rubbing contact of friction material layer and brake disc more convenient, the noise when also having weakened the friction of friction material layer and brake disc to a certain extent.
Description of drawings
Fig. 1 is a structural perspective of the present utility model;
Fig. 2 is a front view of the present utility model.
Embodiment
Provided a kind of brake block as shown in Figure 1, 2 with the dust discharge groove, comprise brake block body 1, described brake block body 1 is fitted mutually by the high temperature compacting by steel disc 11 and friction material layer 12 and is constituted, described friction material layer 12 is provided with dust discharge groove 121 with brake disc end face in opposite directions, described dust discharge groove 121 vertically is arranged on friction material layer 12 and the brake disc end face in opposite directions and runs through up and down, described dust discharge groove 121 is two, and is that center line is symmetrical set with the neutral position of friction material layer 12.The left and right sides is provided with chamfering 122 on described friction material layer 12 and the brake disc end face in opposite directions.
Owing on friction material layer 12 and brake disc end face in opposite directions, set up dust discharge groove 121, so friction material layer 12 can be discharged timely and effectively with the brake disc friction dust that mutual loss is produced when rubbing, dust can't be accumulated, guaranteed the smooth of rubbing surface, also stablize the friction factor of brake block, eliminated the friction noise that is brought because of the rubbing surface out-of-flatness.
