Description

Technical Field

[0001] The utility model relates to the technical field related to the processing of brake pads, in particular to a wear resistance test device for electric vehicle brake pads after processing. Background Technique

[0002] At present, the common braking method of electric vehicles on the market is usually disc braking. Disc brakes, also known as disc brakes, are applicable to various types of vehicles and are composed of a brake disc connected to the wheel and a brake caliper at the edge of the disc. When braking, high-pressure brake oil pushes the brake pads to clamp the brake disc to produce a braking effect. During the processing of brake pads, in order to detect the wear resistance of the brake pads, they need to be ground for a long time.

[0003] Chinese patent with the publication number CN215414858U discloses a wear resistance detection device for automotive brake pads, which relates to the field of brake pad detection equipment. It includes a base, and both ends of the upper surface of the base are fixedly connected with side support plates. A pressure-bearing disc is arranged on one side of one side support plate. The edge of the pressure-bearing disc is fixedly connected with a plurality of annular sleeves distributed in an annular array. The inner cavity of the annular sleeve is movably penetrated and connected with a guide post adapted to the annular sleeve. One end of the guide post is fixedly connected with one side surface of one side support plate, and the other end of the guide post is provided with a fillet. One side surface of the pressure-bearing disc is attached and connected with a brake pad. In the utility model, by fixedly connecting a plurality of annular sleeves on the outer side wall of the pressure-bearing disc, the middle of the annular sleeve is movably penetrated and connected with a guide post, and a pressure sensor is fixedly inlaid on the other side surface of the pressure-bearing disc. Therefore, the pressure sensor can detect the extrusion force between the grinding disc and the brake pad in real time, so as to avoid the influence on the detection of the wear resistance of the brake pad due to too large or too small extrusion force.

[0004] To sum up, the above patent grinds the brake pads through a grinding disc to detect the wear resistance of the brake pads. However, during the detection of brake pads, multiple groups of brake pads need to be spot-checked. The above patent fixes the brake pads with bolts, and this fixing method will cause very troublesome disassembly and assembly of the brake pads, and it takes a lot of time to replace the brake pads, which will affect the detection efficiency. Secondly, since waste chips will be generated when the grinding disc grinds the brake pads, and the above patent is inconvenient to collect the waste chips during the grinding process, it is easy to cause the waste chips to float around and affect the personal health of the staff, and the environmental protection is poor.
