[0002] With the continuous development of the automotive industry, vehicles are traveling at ever-increasing speeds, placing increasing demands on the performance of automotive braking systems. Disc brakes are widely used due to their stable braking performance and excellent heat dissipation. During braking, brake friction is a key parameter for measuring braking effectiveness. Insufficient brake friction can result in excessive braking distances, leading to traffic accidents. Excessive brake friction can cause excessive wear on the brake disc and pads, and even affect the vehicle's handling stability. Therefore, a disc brake friction force detection device is needed to measure brake friction.

It needs to be disassembled and reinstalled, which is time-consuming and labor-intensive. The staff needs to spend a lot of time on repeated installation, and the detection accuracy is easily increased due to the error caused by repeated installation, which reduces the detection efficiency and quality, and increases the detection cost and detection cycle.

[0016] 1. By setting up a flip mechanism, you can start motor 1 and make its output shaft rotate. When the output shaft of motor 1 rotates, it will drive the two sliders 2 closer to each other through the bidirectional threaded rod, thereby clamping the disc brake.
