Abstract
The utility model relates to a novel disc brake pad, comprising a friction block. An arc-shaped notch is arranged on one face of the friction block which is towards a brake disc; the arc-shaped notch is distributed in a radial outward radiation manner around the centre of the brake disc; and the arc-shaped bulge direction is the same as the rotary direction of the brake disc. The novel disc brake pad can achieve the effects of radiating uniformly, reducing temperature and reducing heat fade; simultaneously the powder generated by rain and friction can be discharged smoothly.
Description
Technical field
The utility model relates to the disc brake pad field.
Background technique
Brake block is the direct parts of automobile when realizing braking in the process of moving.For improve the stability that vehicle brakes in the process of running at high speed, current brake system adopts disc brake pad more.
Disc brake pad generally is to be fitted each other through the high temperature compacting by metal layer and friction material layer to constitute.In brake process; After stepping on brake petal, the brake boost pump is started working, and the brake boost pump amplifies pedaling force through brake fluid under the assistance of vacuum and oil pressure and is delivered in the brake caliper; Piston on the brake caliper brake block that the pusher sound is ended that is under pressure; Clamp with the brake disc of tyre rotation producing frictional force, the kinetic energy of automobile is converted into heat energy, thereby plays the effect of brake, stop automobile.In brake process; Can be between disc brake pad and the brake disc in the short time accumulated great amount of heat energy of brake; Particularly Emergency braking or trample when brake continuously in running at high speed, the temperature of brake block can sharply rise at short notice, after temperature rises to a certain degree; The braking effect of brake block can go down even occur failure phenomenon, the heat fade phenomenon promptly occurs.When braking strength is stronger, the brake time is longer, and the heat that gathers on the brake block is if can not well be disperseed; Chemical change will take place in the brake block friction material inner materials; Cause occurring expendable level and smooth mirror-like on the rubbing surface, ablation phenomenon promptly occurs, make that brake is malfunctioning fully.
Disc brake pad mainly is to lean on the frictional force between friction material and the brake disc to brake, in case introducing can cause the material that the two frictional force reduces between friction material and the brake disc, just is easy to take place the phenomenon of brake failure.As being subject to the influence to disc brake pad of rainwater and surface gathered water in the rainy day vehicle traveling process, if fail in time water to be discharged, frictional force can reduce greatly during brake, very easily causes slipping of brake.The fricative dust of brake block and for example, the granular silt of kicking up in the road surface etc., untimely discharge all can reduce the friction effect of brake block, when serious even can cause traffic accident.
In the existing technology, in order to guarantee that fricative dust and rainwater are in time discharged, and guarantee the brake block heat sinking function,, generally can in the middle of brake pad, offer the straight shape fluting vertical or angled with length direction to reduce heat fade.But above-mentioned straight shape fluting can make brake block heat radiation uniformity use wearing and tearing to become unbalanced with it, has reduced the radiating and cooling effect of brake block; The dust that produces in rainwater and the brake process simultaneously can part be jammed in the fluting because straight shape fluting direction and brake disc moving direction are not consistent all the time.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of novel disc brake pad, can reach Homogeneouslly-radiating, cooling to reduce the effect of heat fade, helps simultaneously rainwater and fricative dust are discharged smoothly.
The technological scheme that the utility model adopts in order to solve the problems of the technologies described above is:
A kind of novel disc brake pad comprises slug and brake pad, and slug and brake pad are fitted each other, and said brake pad is provided with arc-shaped groove towards the brake disc one side.
As the further improvement of the utility model, said arc-shaped groove is that the center is the radially outward radiation profiles with the brake disc center of circle, and the arc protrusion direction is identical with the brake disc sense of rotation.
The useful technique effect of the utility model is:
Owing to adopted the novel disc brake pad in the technique scheme; In use; Air gets into the fluting on the brake block along the fluting direction; And be the eddy current shape with brake disc motion and from fluting, get rid of, air flow is taken away the heat that brings because of brake, and its heat radiation situation and cooling-down effect are good all the time.Because brake disc is consistent with force direction and arc-shaped groove direction between brake pad, the dust that produces in rainwater and the brake process edge discharge of slotting more easily makes product performance more stable.

Fig. 2 is the front view of the utility model.
Embodiment
Be described in detail below in conjunction with Fig. 1 and Fig. 2:
A kind of novel disc brake pad; Comprise slug 1 and brake pad 2; Both fit each other; Brake pad 2 is provided with arc-shaped groove 3 towards brake disc one side, and the fluting direction of arc-shaped groove 3 is for being that the center is the radially outward radiation profiles with the brake disc center of circle, and the arc protrusion direction is identical with the brake disc sense of rotation.
Owing to adopted the novel disc brake pad in the technique scheme; In use; Air gets into the arc-shaped groove 3 on the brake block along the fluting direction; And be the eddy current shape with brake disc motion and from arc-shaped groove 3, get rid of, air flow is taken away the heat that brings because of brake, and its heat radiation situation and cooling-down effect are good all the time.Because brake disc is consistent with the force direction and arc-shaped groove 3 directions of 2 of brake pads, the dust that produces in rainwater and the brake process is discharged along fluting more easily, makes product performance more stable.
