Description

Technical Field

[0002] Good car brakes are one of the safety guarantees when driving a car. The braking ability of the brakes is even more related to people's life safety. In the process of brake research and development, each brake developed will be tested for its braking ability to see if it meets national standards.

[0003] Currently, most brake tests on the market install the brake disc on a mounting disc driven by a motor. The motor drives the brake disc to rotate, thereby simulating the driving of a car. When the brake disc is braked to a stop, the motor will be powered off. Due to inertia, the motor rotor will continue to rotate, and the brake disc will gradually stop. During this period, the torque connecting the motor output shaft and the mounting disc will increase, which will easily damage the connecting parts, resulting in a short service life of the detection equipment.
