Description

Multi-conical-surface double-rim wheel

Technical Field

The invention belongs to the technical field of wheels, and particularly relates to a multi-conical-surface double-rim wheel.

Background

Engineering vehicles, trucks and the like need to bear heavy weight for a long time, and particularly the engineering vehicles are often used in complex road conditions. In order to improve the bearing capacity of the vehicle, one or two or more sets of rear wheels are often mounted on each side of the lower part of the vehicle cabin, and 2 rear wheels are mounted on each set of rear wheels side by side, i.e. two wheels are mounted on each rear wheel axle. The two wheels are used simultaneously to share the load borne by the tire, and the wheel with double rims is widely used. However, due to the fact that the road is uneven, the air pressures of the two tires are not consistent, and the like, loads borne by the two tires cannot be the same all the time, so that the concentricity between the two rims is affected due to the fact that the loads are inconsistent easily to occur between the two rims after a long time, the concentricity between the two rims and the hub is also affected, the load difference of the two tires is larger and larger, and the design requirement of balanced load sharing of the original double wheels is gradually lost. When the load of two original wheels side by side is generated, only one wheel is born, the wheel can be overloaded instantaneously, and the long-time and frequent overload causes the wheel including a rim body and a spoke to be easily damaged, cracks, fractures and the like, once the wheel is damaged and deformed, a brake arranged on the wheel can be failed, and even a tire is separated from an axle, so that the wheel is usually "flown out", and a traffic accident of car damage is caused.
