Description

Technical Field

[0001] The utility model relates to the technical field of wheels, in particular to a steel wheel. Background Art

[0002] At present, the known one-piece steel wheel structure is formed by welding two parts, a rim and a hub. The outer rim belongs to the tire mounting component, and the inner hub belongs to the load-bearing and force-transmitting component, and both are formed by cold stamping technology. The traditional one-piece steel wheel requires that the rims on both sides must be symmetrical, and the rim and the hub are welded at the bottom of the rim groove. Due to structural limitations, its shape is not as beautiful as that of an aluminum alloy wheel. Among them, a steel wheel with application number "CN201120115394.7" includes a rim and a hub, and the welding point of the rim and the hub is located at a 5-degree angle of the rim. The utility model can give the hub more modeling planes to achieve the purpose of beauty, so that the cheap steel wheel can reach or approach the appearance effect of the aluminum alloy wheel, but the wheel still has certain shortcomings when used: the hub of the steel wheel is relatively flat in structural design, which makes the hub have many stress weak points, the wheel is easy to fatigue after long-term use, and the wheel performance is not ideal. Utility Model Content
