Apparatus for removing wear dust friction materials in disk brake}

The present invention relates to a friction material wear dust removing device of the disc brake, and more particularly, the friction material wear dust of the disc brake that can adsorb the wear dust of the friction material generated during vehicle braking and discharge the adsorbed dust to the outside after the braking is completed. A technique relating to a removal device.

In general, the disc brake used as the brake device of the vehicle is the hydraulic pressure of the master cylinder is pushed into the wheel cylinder (2) provided in the caliper housing (1) during the operation of the brake pedal of the driver as shown in Figs. When the piston 3 is moved by the hydraulic pressure and the brake pads, which are friction materials 5, are brought into close contact with both sides of the disk 4, the rotation of the disk 4 is stopped by the friction force generated at this time. It is designed to brake the vehicle that is driving.

By the way, the disc brake as described above generates abrasion dust 6 of the friction material 5 when the friction material 5 comes into close contact with the side surface of the disk 4 when the braking force is generated while driving the vehicle. ), There is a problem in that most of the dust (6) is fixed to the wheel (7) to contaminate the wheel (7) as well as to deteriorate the appearance beauty.

Accordingly, the present invention has been made to solve the above problems, and when the friction material is in close contact with the side of the disk, it is possible to absorb and collect the wear dust of the friction material radiated from the surface of the disk, the adsorption after the end of braking It is an object of the present invention to provide a friction material abrasion dust removal device of the disc brake that can prevent the wheel contamination and improve the appearance beauty by discharging the dust to the outside so as not to adhere to the wheel.

Friction material wear dust removing device of the disc brake of the present invention for achieving the above object, the friction material is in close contact with the side of the disk while driving the vehicle when the braking force is generated electrostatic dust of the friction material emitted from the surface of the disk An adsorbent mounted to be adsorbed by using; And a dust cover having a dust discharge hole formed to discharge the dust separated from the absorbent to the outside when the static electricity of the absorbent disappears after the braking is completed.

The adsorbent is mounted on the outer surface of the upper end of the caliper housing, the structure is mounted on the inner surface of the dust cover.

Here, the absorbent material mounted on the upper outer surface of the caliper housing is preferably mounted inclined so that one end is inclined in the direction in which gravity acts.

The dust cover is formed such that the front surface surrounding the inner surface of the disk, the bottom surface surrounding the outer circumferential surface of the disk, the rear surface surrounding a portion of the disk outer surface are continuously connected; The dust discharge hole has a structure formed to be connected to the outside on the connection portion of the front and bottom surface of the dust cover.

The inner surface of the dust cover on which the adsorption material is mounted is characterized in that the bottom surface and the rear surface.

The bottom surface of the dust cover is preferably a structure formed of an inclined surface gradually descending from the connection portion with the rear surface to the dust discharge hole.

According to the present invention, all the wear dust of the friction material radiated from the surface of the disk while driving the vehicle is absorbed and collected by the adsorption material, and after completion of braking, all the dust separated from the adsorption material is discharged to the outside. It is possible to prevent the phenomenon of being stuck to the wheel and accumulate, and through this, there is an effect of greatly improving the pollution prevention and appearance of the wheel.

FIG. 6 is a cross-sectional view taken along the line II-II of FIG. 5.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As described above with reference to FIG. 2, the disc brake device provided in the vehicle includes a caliper housing 1 having an oil passage 1a connected to a brake booster, and a wheel cylinder 2 formed by the caliper housing 1. And a friction material (5) for generating a braking force by friction as the piston (3) is linearly moved by hydraulic pressure and the moving force of the piston (3) is applied to press both sides of the disk (4). ) Is configured to include.

The disc brake configured as described above, when the friction material 5 is in close contact with the side surface of the disk 4 when the braking force is generated while driving the vehicle, as shown in FIG. 3, the wear dust 6 of the friction material 5 is generated. Is characterized in that the structure that can adsorb and discharge the wear dust 6 of the friction material 5 radiated from the surface of the disk 4 to the outside.

That is, the friction material wear dust removing apparatus of the disc brake according to the present invention, as shown in Figures 4 to 6, when the friction material 5 is in close contact with the side of the disk 4 during the vehicle running of the disk (4) The adsorbent 10 mounted to adsorb the wear dust 6 of the friction material 5 radiated from the surface using static electricity, and the adsorbent 10 when the static electricity of the adsorbent 10 disappears after braking is completed. The dust (6) separated from the dust is configured to include a dust cover 20, the dust discharge hole 21 is formed so as to be discharged to the outside.

Here, the adsorbent 10 is a structure in which a plurality is mounted on the upper outer surface of the caliper housing 1, as shown in Figure 4, the adsorbent 10 is mounted inclined so that one end is inclined in the direction in which gravity acts. Is preferred.

That is, the wear dust 6 of the friction material 5 generated during braking while driving the vehicle is all absorbed and collected by the adsorption material 10 by the static electricity generated in the adsorption material 10, and after the braking is completed, the static electricity of the adsorption material 10 is completed. When the extinction disappears, the dust 6 adsorbed to the adsorbent 10 is separated from the adsorbent 10 and freely falls by gravity to be discharged to the outside.

On the other hand, the dust cover 20 has a front surface 20a surrounding the inner surface 4a of the disk 4, a bottom surface 20b surrounding the outer circumferential surface 4b of the disk 4, and the disk ( 4) The rear surface 20c surrounding a part of the outer surface 4c is continuously formed, and the dust discharge hole 21 is connected to the front surface 20a of the dust cover 20 and the bottom surface 20b.
