Description

Disk grinding apparatus for disk brakes {Dicing machine of disk for disk break}

The present invention relates to a disc polishing apparatus for a disc brake of an automobile, and in particular, to allow the bite of the polishing device to be automatically in / out, adjust the angle of the bite to be applied to any disc, and to facilitate the body coupling The present invention relates to a disc polishing apparatus for a disc brake, which makes it easy to adjust the height of a disc drive unit and precisely aligns the center of the disc with a drive motor for rotating the disc.

In general, a disc brake mounted on a vehicle is a device for generating a braking force by bringing a brake pad into close contact with a disk-shaped disk which rotates synchronously with a wheel wheel, and decelerates or stops a running vehicle.

A general embodiment of the disc brake described above will be briefly described with reference to FIG. 1.

The disc brake includes a disc (2) largely synchronously rotated with a wheel wheel, a brake pad (4) sliding on both sides of the disc (2), and a brake pad (4) fixed to an inner knuckle arm of the wheel wheel. The caliper bracket 6 which supports and the caliper body 8 which slides through the caliper bracket 6 so that the brake pad 4 may contact the disk 2 are comprised, and the said caliper bracket 6 is It is fixed to the knuckle arm by a bolt inserted into the fastening hole 9.

The disc brake configured as described above is applied to the brake oil into which the piston of the caliper body 8 is injected by the pressure of the vacuum booster acting as the driver presses the brake pedal and injects the brake oil into the caliper body 8. By advancing by adhering the brake pads 4 located in close contact with the disks 2 to generate frictional forces, the brake pads 4 stop or slow down the rotational motion of the disks 2 by such frictional forces. ) And the high heat generated by the friction between the disk 2 is conducted by the brake pad 4 and the disk 2 to be cooled, or cooled by ventilating through a vent hole formed in the disk 2.

However, the disk 2 as described above does not completely cool the frictional heat generated during braking, and thus, when the frictional heat is not rapidly cooled, the disk 2 is overheated and its shape is deformed. In addition, when the friction between the disk 2 and the brake pad 4 is irregular during the friction process of the disk 2 and the brake pad 4 as described above, the surface of the disk 2 is irregularly worn, resulting in deterioration of brake performance. There was a problem letting.

Accordingly, when the disk 2 is severely deformed, since the disk 2 has to be replaced with a new one conventionally, it causes a waste of resources and costs.

Therefore, the present invention has been devised in view of the above problems, so that the bite of the polishing apparatus is automatically in / out, adjust the angle of the bite to be applicable to any disk, and to facilitate the body coupling The present invention provides a disc polishing apparatus for a disc brake, which makes it easy to adjust the height of the disc drive unit and precisely aligns the center of the disc with the drive motor for rotating the disc.
