Wheel, track and walking wheel are three main kinds of the walking mechanisms on the developed air-cushion vehicles.

目前已开发的气垫车辆所采用的行走机构有轮胎、履带、步行轮等三种，虽然气垫车的垫升机构可以明显降低它们的接地比压从而减少了行驶阻力，但依然存在着行走机构自身重量大，结构复杂以及在软湿地面上的滑转、粘土等一系列问题，另外，限于行走机构的几何尺寸影响，这些车辆的抓地位置仅作用于表层土壤，对于表层土壤含水量严重饱和并且硬底层较深的地面来说，甚至使车辆无法行驶和作业，严重阻碍了气垫车辆的推广应用。
