Abstract

The simulating test table for disc type clutch includes a bench, a motor, one main shaft the motor drives, one friction disc fixture on one end of the main shaft, two friction plates and one cylinder. The main shaft is set through bearing seats on the bench; the friction plates set separately on two sides of the friction disc includes one fixed onto the bench and the other driven with the cylinder; and the main shaft is provided with one flywheel. Before test, the friction disc to be tested is fixed in the fixture. After the main shaft is driven with the motor, the flywheel accumulates energy like a running vehicle and the operation state of the disc type brake is simulated. The present invention has simple structure and accurate simulation result.

Description

technical field [0001] The invention relates to brake performance testing equipment, in particular to disc brake performance testing equipment. Background technique [0002] Brakes are an important part of automobiles and motorcycles, and are crucial safety devices. Their qualified quality and excellent performance are important guarantees for driving safety. With the development of society and the increase of traffic density, the superior braking performance of vehicles has attracted extensive attention from traffic control departments and manufacturers, and higher requirements for driving safety have been put forward. [0003] The evaluation index of the braking performance test on the road is the braking distance. The driver controls the manipulator, and through the transmission (the combination of components that play a role in connecting the manipulator and the brake), the braking distance is generated by the brake and the vehicle. The force in the opposite direction o...
