Wheel components

The wheel is a rotating assembly that bears the load between the tire and the axle. It is usually composed of two main parts, the rim and the spokes (GB / t2933-2009). The rim is the component that mounts and supports the tire on the wheel, and the spokes are the supporting components between the axle and the rim on the wheel. In addition to the above components, wheels sometimes include hubs.

Classification:

1. According to the structure of the spokes, the wheels can be divided into plate type wheels and spoke type wheels.

2. According to wheel material: it can be divided into steel, aluminum alloy, magnesium alloy and other wheels.

3. Install one or two tires according to one end of the axle: it can be divided into single type wheels and dual type wheels.

Spoke plate wheels are widely used in cars and trucks. In addition, there are split type wheels, assembled rim type wheels, reverse mounted wheels, and adjustable wheels.

1. Deep groove rim

This kind of rim is integral, with a deep groove in the middle of its section, which is mainly used for cars and light off-road vehicles. It has a shoulder flange, which is used to place the bead of the outer tire. Its shoulder is usually slightly inclined to the middle, and its inclination angle is generally 5 degrees. The maximum diameter of the inclined part is called the fitting diameter of the tire bead and the rim. The middle of the section is made into a deep groove to facilitate the disassembly and assembly of the outer tire. Deep groove rim has simple structure, large rigidity and small mass, which is most suitable for small-sized tires with large elasticity. However, it is difficult to fit a large and hard tire into such an integral rim.

2. Flat bottom rim

There are many structural forms of this rim. The retaining ring is integral, and an open elastic lock ring is used to prevent the retaining ring from coming out. When installing the tire, first put the tire on the rim, then put on the retaining ring, and push it inward until it passes the annular groove on the rim, and then insert the open elastic lock ring into the annular groove. The wheels of Dongfeng eql090e and Jiefang ca091 cars adopt this type of rim.

3. Split rim

This kind of rim is composed of inner and outer parts. The width of the inner and outer rims can be equal or unequal. The two parts are connected together by bolts. When disassembling the tire, remove the nut. Retaining ring 3 is removable. Some have no retaining ring, but are made of and The inner rim is made into an integral rhyme rim to replace the role of the retaining ring, and the inner rim and the spoke plate are welded together. Dongfeng eq2080, Yan'an SX2150: automobile wheels, that is, rims in this form.
