Oil cylinder lifting type lift brake test platform

The present invention discloses an oil cylinder lifting type lift brake test platform which is formed by a reaction drum brake platform, a sensor, a guide rail supporting frame assembly body and an oil cylinder guide wheel assembly body. The sensor and the guide rail supporting frame assembly body are symmetrically arranged at two ends of the reaction drum brake platform, through the matched installation of the guide wheel and the guide rail structure at the inner side of a guide rail supporting frame, the reaction drum brake platform is driven by the oil cylinder to slide up and down along a vertical direction, and the axis of an oil cylinder piston rod and the central axis of a spokewise weighing sensor coincide. According to the oil cylinder lifting type lift brake test platform, a hydraulic cylinder is employed to carry out the overall lifting of the brake test platform, the brake performance of the load condition of a tested vehicle shaft can be detected, and the oil cylinder lifting type lift brake test platform has the advantages of simple structure, high utilization rate of an existing reaction drum brake platform, convenient installation, small land occupation, easy in and out of a vehicle, and the improvement of detection efficiency.
