Wheel hub

Wheel hub, also known as wheel rim, is a barrel shaped part of the inner contour of the tire used to support the tire, and the center is assembled on the shaft. Common automobile hubs include steel hubs and aluminum alloy hubs. The steel wheel hub has high strength and is often used for large trucks; However, the steel wheel hub is heavy in quality and single in shape, which is not in line with the current low-carbon and fashionable concept and is gradually replaced by the aluminum alloy wheel hub.
