Research on Braking Performance of Disk and Drum Brake Installed on Semitrailer with EBS

Braking performance of tractor-semitrailer plays an important role in driving safety In view of the current installation of drum brakes or disc brakes in tractor-semitrailer of China, the paper analyzes semitrailers from the aspects of test system construction, test methods and results analysis. The brake performance comparison test was carried out on two different brakes, disc type and drum type. The results show that: the semitrailer with EBS installed disc brakes compared drum brakes are combined with tractors to form tractor-semitrailer, the lag time and the braking distance are shorter, especially the thermal degradation performance is greatly improved.
