Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to an integrated wheel hub unit. Background Art

[0002] The automobile wheel hub unit is one of the key components of the automobile. Its main function is to bear weight and provide precise guidance for the rotation of the wheel hub, which requires it to withstand not only axial loads but also radial loads. The inner ring of the automobile wheel hub bearing is mainly connected to the half shaft, and the outer ring of the bearing is connected to the automobile wheel hub. The inner ring of the bearing and the outer ring of the bearing are connected by balls to achieve a rotatable connection between the inner ring and the outer ring of the bearing. The ball structure is precise.

[0003] When the existing device is in use, it is easy to be contaminated with mud and water, thus rusting and leaking. At the same time, most of its joints are flattened, which is easy to cause stress cracks, thus reducing the service life of the device. Utility Model Content
