The hub assembly is represented by a solid part with a half shaft or a product with a splined mounting hole for the hinge half shaft. Vehicle braking is directly dependent on the operation of the hub. It is on it that the brake disc or drum is fixed. In modern cars that use an electronic motion control system, various sensors are installed in the hub. Often, impulse disks are also installed.

The hub performs a wide range of important tasks. It securely holds the rim. This is the basis for fastening the working part of the entire brake system. The hub makes the wheels spin. It holds the nodes on the axle shaft, transmits rotation and fixes the elements of the ABS system. The hub is a strong part, it rarely breaks. But it is important to monitor the condition of its protection lid. A strong impact may cause breakage or distortion.
