Abstract

The invention discloses a test stand for the vehicle brake test. The test stand for the vehicle brake test comprises a first transmission shaft, a second transmission shaft, a power source, multiple brake components and multiple torque measuring mechanisms. Brake discs are fixed on the two ends of the first transmission shaft. The brake discs are fixed on the two ends of the second transmission shaft. The power source is used for driving the first transmission shaft and the second test stand for the vehicle brake test. Multiple torque measuring mechanisms are corresponding to multiple brake components in a one-to-one way and used for detecting the torque of the corresponding brake components. Multiple brake components are corresponding to the brake discs of the first transmission shaft andthe brake discs of the second transmission shaft in a one-to-one way and can brake the corresponding brake discs. Therefore, the brake test of the brake system can be performed before completion of construction of the whole vehicle through cooperation of the first transmission shaft, the second transmission shaft, the power source, multiple brake discs, multiple brake components and multiple torque measuring mechanisms so that the dynamic simulation test of the brake system of the whole vehicle can be realized.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a vehicle braking test bench. Background technique [0002] In related technologies, through the investigation of domestic and foreign OEMs and component suppliers, the brake system test bench mainly tests a single wheel brake or only carries out static PV pressure tests, which cannot achieve dynamic operation of brakes, especially cannot simulate The load change during the braking process of the whole vehicle. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a vehicle brake test bench, which can realize the dynamic simulation test of the whole vehicle brake system. [0004] The vehicle braking test bench according to the present invention comprises: a first transmission shaft, a second transmission shaft, a power source, a plura...
