Description

Technical Field

[0001] This utility model relates to the field of automotive testing equipment technology, and in particular to a positioning target component for automotive four-wheel alignment. Background Technology

[0002] After a car has been driven for a long time and over a long distance, the relative positions of the wheels will become somewhat misaligned. If this misalignment is not corrected, it will not only affect the car's driving performance but also accelerate the wear and tear on components such as the tires and steering mechanism. Therefore, it is usually necessary to perform a four-wheel alignment check on the car after it has been driven for a period of time.

[0003] During four-wheel alignment testing of automobiles, a target is installed on the wheel hubs of the car. Then, the image acquisition device on the alignment instrument or other testing equipment captures the position indication pattern on the target in order to obtain the position information of the four wheels and perform corresponding operations. The problem is that the operation of general alignment targets is inconvenient because they can be rotated and adjusted in the direction of the axis of the mounting shaft and the position is limited.
