Specific embodiment
Structure depicted in Figure of description, ratio, size etc., only to cooperate the revealed content of specification, with
Understand for those skilled in the art and read, is not intended to limit the utility model enforceable qualifications, therefore does not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the utility model institute
Under the effect of capable of generating and the purpose that can reach, it should all still fall in what the revealed technology contents of the utility model can be covered
In range.Meanwhile cited such as "upper", "lower", "front", "rear", " centre " term in this specification, it is merely convenient to chat
That states is illustrated, rather than to limit the enforceable range of the utility model, relativeness is altered or modified, without substantive change
Under more technology contents, when being also considered as the enforceable scope of the utility model.
As shown in Figs. 1-2, the utility model provides a kind of disc brake pad, including backboard 1 and is mounted on rubbing on backboard 1
Cleaning block 3 is provided at least one groove 5 on the rubbing surface of friction block 3, the porous amortisseur bar 6 of high temperature resistant is mounted in groove 5.
Fluted 5 are arranged on the rubbing surface of the utility model disc brake pad, porous resistance resistant to high temperature is installed in groove 5
Buddhist nun's item not only can change the damping of disc brake pad, but also the aperture in amortisseur bar can also adsorb lesser friction material
Abrasive dust, and as the abrasion of the porous amortisseur bar 6 of high temperature resistant is directly discharged with the biggish amortisseur bar wear particle of partial size, it will not
Pollution environment is also not easy to pierce in the gap on wheel hub.The utility model structure is simple, function admirable, raising damping characteristic,
It reduces noise, improve the feature of environmental protection, can effectively prevent fine dust and enter spider creep.
In order to further increase heat dissipation area, as shown in Figure 1, the left and right sides of friction block 3 is respectively arranged with from friction block 3
Rubbing surface inclination extend to the inclined-plane 4 of friction block side 2, the inclined-plane 4 of two sides is symmetrical set on friction block 3, can
Reduce noise and improves abrasive dust export ability.
Inclined-plane 4 and the angle of rubbing surface are not limited in principle in the utility model, but in view of effective friction area and
The dual requirements of heat dissipation, generally mostly select between 5-20 °, by test of many times the present embodiment further by inclined-plane 4 with rub
The angle in wiping face is preferably 10 ° -15 °.
In order to more intuitively determine the replacement of disc brake pad, the friendship on inclined-plane 4 and friction block side 2 in the present embodiment
Line is parallel with backboard 1, and is located in the limiting wear plane of friction block 3.When discovery is located at the inclined-plane 4 on the outside of disc brake pad
In the absence of can directly be replaced.
