[0002] The wheel hub is the rotating part of the wheel core connected to the inner wheel steel of the tire through the column, that is, the metal part that supports the center of the tire and is mounted on the shaft. The wheel hub will deform during the production, processing and heat treatment process, resulting in deviations in the shape and size of the wheel hub. According to national standards and industry standards, the wheel hub runout is an important parameter for testing the quality of the wheel hub, and it is also an important technical performance that reflects the vehicle's runout and the stability of the vehicle body when the vehicle is driving. In order to ensure the quality of the wheel hub, the radial and axial runout of the wheel hub must be tested.
