Description

Technical Field

[0001] The invention relates to the technical field of tire detection, and in particular to a fixing device for detecting automobile tires. Background Art

[0002] When a car is driven for a long time, the tire is made of rubber, which may cause the tire to deform or stick to some stones. If the wheel is driven again, it will affect the stability of the vehicle and there may even be a risk of a tire blowout. It is necessary to perform a dynamic balance test on the car tires. Tire dynamic balance test is an important task in car maintenance. It is used to ensure that the tires will not be unbalanced when rotating, thereby avoiding shaking, noise or abnormal wear of the vehicle during driving. The tire dynamic balance test is to detect whether the tire rotation shape is displaced by rotating the car tire at high speed.

[0003] At present, the dynamic balance detection device in the prior art is not suitable for detecting automobile tires in emergency situations, resulting in the tires being unable to be used in time, affecting the vehicle utilization rate.

If the detected tires are not limited and damped, the dynamic balance detection device will be damaged, and the detection accuracy of the dynamic balance of the automobile tire will be affected. In addition, in the face of different vehicle tire size requirements, it is inconvenient to fix tires of different sizes, affecting the practicality of the dynamic balance detection device.
