The five major components of the wheel hub are the rim, the spoke, the offset, the rim and the groove bottom. The rim cooperates with the tire assembly and supports the wheel portion of the tire. The spokes are mounted and connected with the hub of the axle to support the wheel part of the rim.
Offset distance refers to the distance between the center surface of the rim and the mounting surface of the spokes, which can be divided into positive offset distance, zero offset distance and negative offset distance. The rim is the part of the rim that holds and supports the direction of the tire. The bead seat, also known as the mounting surface, is in contact with the bead of the tire and supports the portion of the rim that maintains the radial direction of the tire. The groove bottom is for the convenience of tire assembly and disassembly, and there are pits with a certain depth and width on the rim. The valve hole is the hole in which the tire valve is installed.
The wheel hub is the rotating part of the wheel core connected by the inner profile of the tire through the column, that is, the metal part that supports the center of the tire and is mounted on the shaft, also known as the rim, the steel ring, the wheel, and the tire bell. There are many types of wheel hubs according to diameter, width, forming method and material. The hub includes many parameters, and each parameter will affect the use of the vehicle, so before modifying and maintaining the hub, you must first confirm these parameters.
