Description

Technical Field

[0001] The utility model relates to the technical field of tire detection, in particular to a tire wear-resistant detection machine. Background Art

[0002] Tires are important parts of cars. When a car is driving, the tires are always in contact with the ground and will continue to wear. If the tires are excessively worn, problems such as performance degradation and insufficient grip will occur, which is not conducive to the safe driving of the car. Therefore, after the production of car tires is completed, it is often necessary to use wear resistance testing devices to test the wear resistance of the tires.

[0003] When using the existing tire wear detection device, the tire is generally placed on the detection wheel, and the tire is rotated quickly by rotating the detection wheel, so as to perform wear detection on the tire. However, during the detection, the tire is usually placed on the top of the detection wheel, and only one tire is detected at a time, and the detection efficiency is low. Since the detection wheel is a circular structure, the contact between the detection wheel and the tire cannot well simulate the driving process of the car on the road, resulting in a large deviation between the detection data and the actual use. In addition, when detecting the deceleration of the tire, the tire will follow the deceleration, and the detection wheel and the tire will not rotate relative to each other, and the grip performance of the tire under braking cannot be detected, and the detection function is relatively single.
