Problems solved by technology

However, for ordinary car drivers, it is not necessarily possible to correctly judge whether the brake shoe has reached the wear limit.
Once the judgment is incorrect, excessive use of brake shoes will have serious safety hazards

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] like figure 1 and figure 2 The shown brake shoe includes a liner 1 and a friction plate 4 fixed together. The friction plate 4 has an opposite front and a back side. The back side of the friction plate 4 is in contact with the liner 1. The first Through hole 3 and the second through hole 7, the first through hole 3 is fixed with the first colored block 2, the second through hole 7 is fixed with the second colored block 6, when the brake shoe is installed on the automobile, the first The distance between the coloring block 2 and the second coloring block 6 and the center line of the brake disc 5 is different, and the first coloring block 2 and the second coloring block 6 have a color that is clearly contrasted with the color of the brake disc 5. In this embodiment, the first The colors of the first colored block 2 and the second colored block 6 are both red, and th...

Abstract

The invention relates to a braking shoe which comprises a liner and a friction piece. The liner and the friction piece are fixed together. The friction piece is provided with a front face and a back face which are opposite. The back face of the friction piece is in contact with the liner. At least two coloring blocks are arranged in the friction piece. When the braking shoe is arranged on a vehicle, the distances between different coloring blocks and the center line of a braking disc are different. The coloring blocks have the color in contrast to the color of the braking disc. The end faces, close to the front face, of the coloring blocks are effect faces. The distances between the effect faces of different coloring blocks and the front face are different. The effect face, farthest from the front face corresponds to the wear limit of the friction piece. When the braking disc is in contact with the effect face, the friction piece reaches the wear limit. Under the premise that manufacturing cost is hardly increased, a car driver can observe the wear situation of the braking shoe clearly; the fact that the car driver can accurately judge whether the braking shoe needs to be replaced is guaranteed; braking failure accidents caused by overusing of the braking shoe can be effectively avoided.

Description

technical field [0001] The invention relates to an automobile brake device, in particular to a brake shoe. Background technique [0002] At present, most cars use disc brakes, which include components such as brake calipers, brake shoes and brake discs. The braking principle is to push the brake calipers by the oil pressure controlled by the master brake cylinder, let the brake shoes on the brake calipers clamp the brake disc, and use the friction force between the brake shoes and the brake disc brake the car. [0003] The friction between the brake shoes and the brake disc wears down the brake shoes. When the brake shoe is worn to the wear limit, it must be replaced, otherwise serious failures such as brake failure will occur. Usually, it is determined whether the brake shoe has reached the wear limit by judging the wear amount of the brake shoe. The wear amount of the brake shoe can be judged by the remaining thickness of the friction plate on the brake shoe, but this j...
