Background

The american initial Global AIR CYLINDER WHEELS (GACW) developed a new wheel which is mainly suitable for mining vehicles, replacing the current shock absorbing function of the vehicle suspension and the gas shock absorbing function of the conventional pneumatic tire by turning over the structure of the conventional tire. In particular, reference is made to CN 113272154B wherein the suspension between the inner and outer rims is achieved by the relative arrangement of the shock absorber to achieve shock absorbing.

However, the developed wheel structures are mostly suitable for mine vehicles, and the differences between the developed wheel structures and the traditional road vehicles are obvious, and the main reasons are that the mine vehicles are low in running speed, heavy in vehicle body load and large in weight change difference, so that the wheel structures are more focused on the shock absorption support stability of the wheel structures. The road vehicle has higher requirements on tire damping frequency, stress balance and traction transmission because of the need of ensuring effective operability of corresponding high-speed running and vehicle stopping and starting.
