Description

Technical Field

[0001] The present invention relates to the technical field of tire detection, and in particular to a tire anti-skid performance detection device for new energy vehicles. Background Art

[0002] With the continuous enhancement of people's environmental awareness and the continuous reduction of fossil energy, new energy vehicles have also developed rapidly. Compared with traditional vehicles, new energy vehicles are more environmentally friendly and energy-saving. However, with the gradual popularization of new energy vehicles, people are paying more and more attention to the driving safety of new energy vehicles. Tires are one of the indispensable components of new energy vehicles, and the anti-skid performance of tires largely determines the driving safety of the car. Tires with poor anti-skid performance increase the braking distance of the car during driving and are more prone to skidding, which will cause serious safety accidents. Therefore, in the production and manufacturing process of new energy vehicles, detection equipment is needed to test the anti-skid performance of tires.

[0003] Since cars experience different driving environments during actual use, tires will come into contact with road surfaces of different conditions. However, most existing tire anti-skid performance testing devices have a single function, making it inconvenient to perform multi-environment testing on tires, thus affecting the accuracy and reliability of tire anti-skid test results and having certain usage defects. In the existing technology, most tire anti-skid tests use a tire side support mode or a simulated road tilt support mode, which cannot truly simulate the anti-skid performance of new energy vehicle tires facing the ground. In addition, when testing in multiple modes, dirt will adhere to the tire surface, greatly increasing the detection error. Therefore, it is necessary to design a corresponding technical solution to solve this problem. Summary of the Invention
