A self-cleaning alarm brake pad

Abstract

The invention provides a self-cleaning type warning brake pad. The self-cleaning type warning brake pad comprises a steel plate and a friction plate. The friction plate is fixedly arranged on the steel plate, an early warning line is arranged on the friction plate, a plurality of grooves are formed in the friction plate, and cleaning and warning assemblies are arranged in the grooves. Each cleaning and warning assembly comprises an elastic connecting piece, a warning piece and a cleaning block. One end of each elastic connecting piece is fixedly connected with the bottom of the corresponding groove, the other end of each elastic connecting piece is fixedly connected with the corresponding warning piece, and the cleaning blocks are fixedly arranged on the warning pieces. In the natural state, the cleaning surface, facing the brake pad, of each cleaning block is higher than the friction surface, facing the brake pad, of the friction plate all the time, and the surface of contact between each warning piece and the corresponding cleaning block is flush with the early warning line. According to the self-cleaning type warning brake pad, the cleaning blocks can make contact with all the friction surfaces of the brake pad, the effect of completely cleaning the surface of the brake pad is achieved, the higher braking force is provided, the braking noise cannot be generated, the warning reminding function is fulfilled, and the owner of an automobile can be reminded to timely replace the damaged friction plate.

Description

technical field [0001] The invention relates to the technical field of motor vehicle brakes, in particular to a self-cleaning alarm brake pad. Background technique [0002] During the braking process, it is inevitable that there will be a lot of sand, mud or other hard particles on the brake disc. When the brake pads rub against the brake disc, the sand, mud or other hard particles stuck on the friction disc will It will be sandwiched between the brake pad and the brake disc, causing the wear of the brake pad and the brake disc, and also affecting the braking effect of the brake pad. Moreover, during the braking process of the car, the friction material of the friction plate will be gradually worn due to friction. After the friction material is used up, the friction plate should be replaced in time, otherwise the braking effect will be lost and the brake disc will be damaged; It will affect the sensitivity of the brakes. Today's brake friction pads do not have the function ...

[0002] During the braking process, it is inevitable that there will be a lot of sand, mud or other hard particles on the brake disc. When the brake pads rub against the brake disc, the sand, mud or other hard particles stuck on the friction disc will It will be sandwiched between the brake pad and the brake disc, causing the wear of the brake pad and the brake disc, and also affecting the braking effect of the brake pad

Moreover, during the braking process of the car, the friction material of the friction plate will be gradually worn due to friction. After the friction material is used up, the friction plate should be replaced in time, otherwise the braking effect will be lost and the brake disc will be damaged; It will affect the sensitivity of the brakes. Today's brake friction pads do not have the function of reminding people to change the friction pads. This will bring a lot of inconvenience to the daily maintenance of car owners and pose a great safety hazard.
