Abstract

The utility model relates to the field of automobile brake pad, in particular to a brake pad, which comprises a steel disc (1) and a friction material layer (2) the lower part of which is jointed with the steel disc, wherein, the friction material layer (2) is provided with a powder discharge groove (3). The brake pad has no dust accumulation, ensures the friction coefficient to be stable, and eliminates the noise caused by uneven surface.

Description

A kind of brake block
Technical field
The utility model relates to automobile and uses the brake block field.
Background technique
Brake block mainly is made of by the high temperature compacting steel disc and friction material layer.What friction material layer was used is dusty material, in the braking automobile process, make under the situation of power of automobile brake when friction material layer and the mutual friction-produced of friction disk, friction material layer can produce abrasion, at this moment the dust that abrasion produce can't be discharged the slit between friction material layer and the friction disk, the dust accumulation can cause the friction factor instability of brake block, thereby and can make the product surface out-of-flatness produce noise.
Summary of the invention
The purpose of this utility model is the technical problem that can't discharge for the dust that the abrasion that solve existing brake block existence produce, provides a kind of dust conveniently to discharge, stable friction factor, the smooth brake block that can not produce noise of product surface.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of brake block comprises the friction material layer of steel disc and below thereof and its applying, and described friction material layer is provided with a dust-discharging slot.
As preferably, dust-discharging slot vertically is arranged on the friction material layer and up/down perforation, and dust-discharging slot is divided into symmetrical left and right sides two-part with friction material layer, and the stressed even friction effect of symmetrical two-part friction material layer is good.
As preferably, brake block is a disc brake pad.
Owing to adopted a kind of brake block of above-mentioned technological scheme, friction material layer is provided with dust-discharging slot, dust-discharging slot does not promptly influence friction material layer and contacts with friction disk, the dust that abrasion produce can be discharged easily simultaneously, do not have the dust accumulation, guaranteed the stable of brake block friction factor, eliminated because of surface irregularity and produced noise.
Description of drawings
Fig. 1: the utility model embodiment's structural representation.
Embodiment
Make a detailed explanation below in conjunction with 1 pair of embodiment of the present utility model of accompanying drawing.
A kind of brake block as shown in Figure 1, friction material layer 2 by steel disc 1 and its below constitutes by the high temperature compacting, friction material layer 2 is provided with a dust-discharging slot 3, dust-discharging slot 3 vertically is arranged on the friction material layer 2 and up/down perforation, and dust-discharging slot 3 is divided into symmetrical left and right sides two-part with friction material layer 2.Above-mentioned brake block is a disc brake pad.
Dust-discharging slot 3 does not influence friction material layer 2 and contacts with friction disk, friction material layer 2 and the mutual fricative dust of friction disk can be discharged to side to the dust-discharging slot 3 that passes through to connect simultaneously, do not have the dust accumulation, guaranteed the stable of brake block friction factor, eliminated because of surface irregularity and produced noise.
The foregoing description only is a this patent mode of execution preferably, and the structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection domain of this patent.

Claims (3)

1. brake block comprises the friction material layer (2) of steel disc (1) and below and its applying it is characterized in that described friction material layer (2) is provided with a dust-discharging slot (3).
