Description

Technical Field

[0001] The utility model relates to the technical field of wear resistance detection of automobile brake pads, and specifically relates to an automobile brake pad wear resistance detection device. Background Technique

[0002] The working principle of braking mainly comes from friction. By using the friction between the brake pads and the brake discs and between the tires and the ground, the kinetic energy of the vehicle in motion is converted into heat energy after friction to stop the vehicle. A set of good and efficient braking systems must be able to provide stable, sufficient, and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and each slave cylinder, and to avoid hydraulic failure and brake fade caused by high heat. Therefore, the brake pads play a very important role, and the wear resistance detection of the brake pads is also particularly important;
