Description

Technical Field

[0001] The utility model relates to the technical field of automobile detection, in particular to an automobile brake testing platform. Background Art

[0002] The automobile brake test bench is an inspection device that detects the vehicle's braking performance by measuring the reaction force of the wheel brake force acting on the force measuring roller. Automobile braking performance is one of the important factors for safe driving and is directly related to the traffic safety of people. As the speed of automobiles increases, the quality of automobile braking performance is particularly important to ensure traffic safety. Therefore, automobile braking performance is an important part of automobile testing.

[0003] A Chinese patent, a roller reaction type automobile brake test bench, with the announcement number CN216410677U, adds a drying component, which includes a box, a heating wire tube, a dust screen and a fan. By connecting the heating wire tube to an external power supply and connecting the heating wire inside the heating wire tube to current, the heating wire converts electrical energy into thermal energy, and by pressing the fan switch, the fan blows hot air to dry the bench to prevent the wheels from slipping during testing. This solves the problem that moisture may exist on the surface of the roller in the previous roller reaction type automobile brake test bench, causing the wheels to slip during specific testing and affecting the final braking force test results. However, during the test process, the contact between the automobile tire and the roller may leave residues such as oil, mud and sand. These residues not only affect the cleanliness of the test bench, but may also interfere with subsequent tests and reduce the test accuracy. Therefore, an automobile brake test bench is proposed to solve the above problem. Utility Model Content
