Experimental Study on Thermal Decay Performance of Disk and Drum Brake
Abstract
The braking thermal decay performance of large-scale freight vehicle is an important influencing factor to braking safety. Presently, the utility ratio of disk brake in large-scale freight vehicle is low. In this paper, thermal decay performance comparative test study on disk and drum brake mounted in semitrailer is conducted. The test result shows that During the thermal decay test, the temperature change of disk brake is small in less than 150℃ and big more than 150℃. Temperature change of drum bake is more stable. The disk brake can provide semitrailer with larger brake torque and better thermal stability. It is of more obvious advantages than drum brake.
