Abstract
The utility model discloses a disc brake pad, including a brake body. The brake body is made by the high temperature suppression and mutual joint of steel pads and friction materials. An extended side is arranged on the steel pad. A cylindrical convex column toward the friction material is arranged on the extended side. A torsion spring is arranged on the cylindrical convex column. One end of the torsion spring is connected with the layer of friction material and the other end is connected with the brake body. A limited torsion spring and a gland which is disjointed with the cylindrical convex column are arranged on the cylindrical convex column. Because a torsion spring is arranged on the cylindrical convex column and one end of the torsion spring is connected with the layer of friction material, when the brake pad is worn to a certain limit, the brake pad can rub the torsion spring. When the torsion is rubbed, the torsion can make a harsh warning sound to remind the users to change the brake pad. The structure is not only simple but also has an accurate alarm. The utility model brings great convenience to the users.
Description
Technical field
The utility model relates to a kind of automobile brake block, especially a kind of disc brake pad.
Background technique
At present, automobile mainly is made of by the high temperature compacting steel disc and friction material layer with brake block.In the braking automobile process, friction material layer and brake disc mutual friction mutually produce the power that makes automobile brake, friction material layer constantly wears away, thereby the thickness that makes brake block mainly is that the thickness of friction material layer is more and more littler, when thickness reaches certain limit, must in time change brake block.And existing automobile does not have warning device usually with brake block, the brake block that is installed on the chuck in use generally is a usage degree (as: single kind specification product is said and must be changed after this product of explanation uses the 1W kilometer) of understanding product by explanation, substantially all be to judge the replacing brake block in this way, and the use condition difference of each car can not be lumped together, there is not reliable warning device just can't accurately judge its replacing opportunity, change relatively waste in advance, change the untimely potential safety hazard that just has.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of disc brake pad that will accurately report to the police when brake block may wear to certain limit.
For achieving the above object, the utility model provides a kind of disc brake pad, 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, described steel disc is provided with an extending end, extending end is provided with a cylindrical projection towards friction material layer, be arranged with a torsion spring on the cylindrical projection, described torsion spring one end and friction material layer are conflicted, the other end of torsion spring and brake block body set firmly, and also are provided with the gland that a restriction torsion spring and cylindrical projection are thrown off on the described cylindrical projection.
The beneficial effects of the utility model are: owing to be arranged with a torsion spring on the cylindrical projection of steel disc extending end, described torsion spring one end and friction material layer are conflicted, so when brake block may wear to certain limit, the friction brake sheet torsion spring that will rub simultaneously again, torsion spring is worn, and will send ear-piercing chimes of doom and remind the user in time to change brake block, such structure setting, not only simple in structure, and report to the police accurately, bring convenience to the user.
The utility model can further be set to described friction material layer and brake disc end face in opposite directions is provided with a dust discharge groove that runs through up and down.
Adopt said structure, owing on friction material layer and brake disc end face in opposite directions, set up a dust discharge groove, 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.
Description of drawings
Fig. 1 is a structural perspective of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1.
Embodiment
As Fig. 1, provided a kind of disc brake pad shown in 2, 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 steel disc 11 is provided with an extending end 111, extending end 111 is provided with a cylindrical projection 1111 towards friction material layer 12, be arranged with a torsion spring 2 on the cylindrical projection 1111, described torsion spring 2 one ends 21 are conflicted with friction material layer 12, the other end 22 and the brake block body 1 of torsion spring 2 set firmly, also be provided with the gland 1112 that a restriction torsion spring 2 and cylindrical projection 1111 are thrown off on the described cylindrical projection 1111, described friction material layer 12 is provided with a dust discharge groove 121 that runs through up and down with brake disc end face in opposite directions.
Owing on the cylindrical projection 1111 of steel disc extending end 111, be arranged with a torsion spring 2, described torsion spring 2 one ends 21 are conflicted with friction material layer 12, so when brake block may wear to certain limit, the friction brake sheet torsion spring 2 that will rub simultaneously again, torsion spring 2 is worn, and will send ear-piercing chimes of doom and remind the user in time to change brake block, such structure setting, not only simple in structure, and report to the police accurately, bring convenience to the user.
Claims (2)
1. disc brake pad, it is characterized in that: 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, described steel disc is provided with an extending end, extending end is provided with a cylindrical projection towards friction material layer, be arranged with a torsion spring on the cylindrical projection, described torsion spring one end and friction material layer are conflicted, the other end of torsion spring and brake block body set firmly, and also are provided with the gland that a restriction torsion spring and cylindrical projection are thrown off on the described cylindrical projection.
2. a kind of disc brake pad according to claim 1 is characterized in that: described friction material layer and brake disc end face in opposite directions is provided with a dust discharge groove that runs through up and down.
