The wheel hub unit is an important component that connects the wheel and axle, consisting of the rim, spoke, wheel hub, and tire. The wheel rim is a component that installs and supports the tire, providing support and heat dissipation functions. The spokes connect the wheel rim and hub, serving as a bridge. The hub provides central support and is connected to the axle. Hub units can be divided into various types based on their structure, and car owners can choose the appropriate hub unit for their vehicles according to their needs.
During the work process, the hub unit mainly relies on the hub bearing unit for support. The hub bearing unit is composed of internal bearings, sealing rings, and dust covers. Bearings are used to provide the sliding performance of rolling bearings, dust covers are used to prevent dust and impurities from entering the bearings, and sealing rings are used to prevent lubricating oil leakage. During the maintenance process of the hub bearing unit, it is important to note that it is not allowed to be opened.
During use, the working principle of the wheel hub bearing unit is to drive the rotation of the wheel hub and tire through the rotation of the axle, thereby achieving the rotation of the wheel. At the same time, the hub bearing unit also bears the force and torque generated by the wheel rotation, ensuring the driving stability and handling performance of the vehicle.
When inspecting the wheel hub bearing unit, if there are problems such as oil leakage, large or small clearance, noise, etc., it is necessary to replace them in a timely manner to avoid affecting the driving safety of the vehicle. During the replacement process of the wheel hub assembly, attention should be paid to the installation sequence and tightening torque to ensure the firmness and stability of the wheel hub unit.
