[0002] As we all know, the new energy vehicle tire wear resistance detection device is an auxiliary device used in the production process of new energy vehicles to detect the wear resistance of its tires, so as to evaluate the quality of a batch of tires. It has been widely used in the field of production; the existing detection device for tire wear resistance of new energy vehicles includes a detection base, a tire mounting plate is arranged on the detection base, and a variable speed motor is installed at the rear end of the tire mounting plate. A hydraulic cylinder is arranged on the top of the seat, and a hydraulic rod is arranged on the top of the hydraulic cylinder, and a friction plate is arranged on the top of the hydraulic rod, and the friction plate is located under the tire mounting plate; the existing new energy vehicle tire wear resistance testing device uses , install the tire to be tested on the tire mounting plate, and drive the tire mounting plate and the tire to rotate through the variable speed motor. When the belt tire rotates to a certain speed, the hydraulic cylinder drives the hydraulic rod to move upward, and the hydraulic rod drives the friction plate to move upward. Until the top of the friction plate comes into contact with the bottom of the high-speed rotating tire and exerts a certain pressure on the bottom of the tire, after a period of time, turn off the variable speed motor, observe the wear of the tire, and obtain the wear resistance of the tire; now In the use of some new energy vehicle tire wear resistance testing devices, it is found that it cannot detect the wear resistance of tires according to the actual use of the tires, and the test results obtained are not representative, resulting in low practicability ; And when the high-speed rotating tires are in contact with the friction plate, it is easy to be dangerous, and the safety is low
