DESIGNING A LOADED BRAKE TESTBED FOR VEHICLES USING THE DEPENDENT SUSPENSION SYSTEM

Abstract

Currently, all vehicle registration centers are applying the procedure to check the quality of the brake system when vehicles are in unloaded mode. Although this procedure still guarantees a quality of the brake system according to the current standard TCN 224-2001, it still hides the risk of traffic accidents in terms of the loaded mode. This paper introduces the calculation and design of a loaded brake test platform for vehicles in order to minimize the difference in braking efficiency between testing on the test platform and on the road. The design principle is to use available facilities at vehicle registration centers and not change the layout of the lines. Two hydraulic cylinders that are linked to the axle via the belt will generate a maximum load of 150000 (N). Therefore, the design scheme can be met in assessing the braking efficiency at each axle for most of the commercial vehicles in circulation. The results of the paper are important theoretical backgrounds for the future study of loaded brake testbed.
