Abstract

The invention relates to a test stand for testing a brake performance of an electric vehicle. The test stand comprises a first support unit and a second support unit, wherein the first support unit and the second support unit are arranged on a test stand rack and are used for supporting a left front wheel and a right front wheel and a left rear wheel and a right rear wheel of an electric vehicle respectively. The first support unit includes two left front wheel support rollers and two right front wheel support rollers, wherein the two left front wheel support rollers and the two right front wheel support rollers are arranged below the front sides and rear sides of the left front wheel and the right front wheel respectively. The second support unit includes two left rear wheel support rollers and two right rear wheel support rollers, wherein the two left rear wheel support rollers and two right rear wheel support rollers are respectively arranged below the left sides and right sides of the left rear wheel and the right rear wheel. The second support unit is connected with a detection module; the detection module is used for detecting values of the kinetic energy caused by the left rear support rollers and the right rear wheel support rollers and transmitting the values of the kinetic energy to a processing module; and the processing module is used for analyzing the kinetic energy to determine the brake performance of the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to an electric vehicle braking performance testing test bench. Background technique [0002] Before the mass production of automobiles, various performance indicators of the automobile need to be tested. Generally, the road test is used to test the performance indicators of the automobile under various working conditions. The initial investment cost of the above road test method is relatively high. In the prior art, most of the cars to be tested are placed on the test bench, and the test bench is used to simulate various working conditions of the car on the road, so as to test the various performances of the car. Compared with the traditional road test, the test bench has the advantages of short cycle, high speed, high precision and low cost. However, most of the test benches in the prior art are designed for ordinary internal combustion engine vehicles, and there is no Tes...
