Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a brake disc wear detection device. Background Technique

[0002] The brake disc is an important component in the automotive braking structure. When the vehicle brakes, the brake caliper clamps the brake disc to generate braking force, causing the vehicle to stop. However, after long-term use, the brake disc will wear, so it is necessary to regularly detect the wear of the brake disc.

[0003] Most of the existing brake disc wear detection devices can only perform single-sided detection during use. For example, the utility model with the patent number CN217058748U can only perform single-sided detection on the brake disc when detecting the brake disc. If it is necessary to detect the wear condition of the other side, the brake disc needs to be removed, turned over and reinstalled before detecting again, which is time-consuming and laborious. Frequent disassembly also causes greater wear to the device structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a brake disc wear detection device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A brake disc wear detection device includes a base and a motor. A first fixing block is fixed on the base, and a plurality of electric telescopic rods are fixed on the first fixing block. The output ends of the plurality of electric telescopic rods are fixed with a mounting block. On one side of the mounting block, support rods are fixed on both opposite sides. A second fixing strip is fixed between the two support rods. A plurality of detection component bodies are evenly inserted into the second fixing strip. A fourth bevel gear is sleeved on the output end of the motor. A third bevel gear is meshed with the side of the fourth bevel gear. A transmission shaft is sleeved inside the third bevel gear. A second bevel gear is sleeved on the end of the transmission shaft away from the third bevel gear. A first bevel gear is meshed with the side of the second bevel gear. A rotating shaft is sleeved inside the first bevel gear. A fixing plate is sleeved on the end of the rotating shaft close to the first bevel gear. On the side of the fixing plate away from the third bevel gear, there are a plurality of support rods. The ends of the support rods are fixed with a second fixing strip. A plurality of detection component bodies are inserted into the second fixing strip. The end of the detection component body is fixed with a first fixing strip.

[0007] Preferably, a limiting ring and a nut are sleeved on the end of the rotating shaft away from the first bevel gear. The nut is threadedly connected to the rotating shaft. A brake disc is arranged between the limiting ring and the nut. The limiting ring cooperates with the nut to fix the brake disc on the rotating shaft.

[0008] Preferably, an outer shell is provided on the base, and a protective cover is provided on one side of the outer shell. The outer shell is used to protect the first bevel gear, the second bevel gear, and the third bevel gear.

[0009] Preferably, a plurality of limiting plates are fixed on one side of the fixing plate close to the first bevel gear. The limiting plates are used to limit the position of the transmission shaft.
