The wheel is a barrel-shaped part, the inner contour of the tire supports the tire, and the center is a metal part mounted on the shaft. According to different diameters, widths, molding methods and materials, there are many kinds of wheels.

The structure of automobile wheel hub is as follows:

① Rim: the wheel part that cooperates with the tire assembly to support the tire; ② Spoke: install the wheel part connected to the hub and support the rim; ③ Offset (ET): the distance between the center surface of the rim and the spoke installation surface. There are positive offset, zero offset, and negative offset; ④ Rim: the part of the rim that holds and supports the direction of the tire; ⑤ Bead seat: also called the mounting surface, which is in contact with the tire rim, supports the rim, and maintains the radial direction of the tire; ⑥ Groove Bottom: In order to facilitate tire disassembly and assembly, there are pits with a certain depth and width on the rim; ⑦ Valve hole: the hole for installing the tire valve.

Advantages of aluminum alloy wheels:

① Compared with wheels of other materials, each standard weight is about 2kg lighter than steel wheels of the same size, which saves fuel; ② Durable, impact resistance, tensile strength and thermal strength are higher than those of other materials; ③ High precision and balanced driving performance Good; ④ Good heat dissipation. During long-distance high-speed driving, the tires can be maintained at a suitable temperature, thereby prolonging the service life and reducing the chance of puncture; ⑤ Prolonging the engine life, according to the graph of engine load and power, when the load increases to To a certain extent, its power will be reduced and the engine load will be reduced, which will naturally reduce failures and prolong life; ⑥The aluminum alloy wheels have a variety of designs to enhance the value and beauty of the car.
