Abstract

The present invention discloses a truck brake test bench, and relates to the field of automobile brake equipment. The test bench comprises: a test stand main body and a brake assembly to be tested installed on the test bench main body, a test slot is formed on top of the test bench main body, and further includes: a brake shaft, rotatably disposed in a test slot; a brake disc, installed on the brake shaft and located between two brake pads of the brake assembly to be tested; a first motor, installed in the test slot for driving the brake shaft to rotate; and a cooling shaft rotatably disposedin the test slot; the test bench is provided with a cooling block, wherein the cooling block is provided with a phase change heat absorbing material, and the cooling block can quickly absorb heat after contacting the brake disk, thereby effectively reducing temperature of the brake disk, thereby enabling to continue the test and improving test efficiency, and is safer compared to water cooling, avoiding uneven thickness of the brake disc surface due to uneven water cooling.

Description

technical field [0001] The invention relates to the field of automobile brake equipment, in particular to a truck brake test bench. Background technique [0002] The brake is an important part of the truck, and it is a crucial safety device. Its qualified quality and excellent performance are an important guarantee for driving safety. With the development of society and the increasing traffic density, the superior manufacturing of vehicles Dynamic performance has attracted extensive attention from traffic control departments and manufacturers, and puts forward higher requirements for driving safety; [0003] Both the brake pads and brake discs of the brake have a heat attenuation effect. When braking, the friction between the brake disc and the brake pads will generate a lot of heat, which will cause the brake discs and brake pads to overheat in the case of long downhill or multiple braking. As a result, the braking effect is poor. During the test of the brake, it is necess...
