Snowmobile drive belts are similar to tank belts, but there are some differences. Snowmobile drive belts are made of lighter rubber, which can increase mobility and speed, while tank belts are made of rigid materials, because they must withstand impact and explosion when carrying heavy objects. Tank belts can usually steer and drive vehicles, while steering of snowmobiles is controlled by handles and skis. In some cases, the belts of snowmobiles will turn successfully, while the wheels will often fail. For example, on soft, smooth or unstable ground, the snowmobile drive belts can spread the weight of the vehicle to a larger surface, so as to drive smoothly, while wheeled vehicles cannot get traction force on these grounds.
Snowmobile drive belts can prevent heavy snowmobiles from falling into soft snow, just as snowboards and snowshoes spread people's weight over a wider range. Snowmobile drive belts also provide traction to smooth surfaces such as snow and ice, where ordinary wheeled vehicles slip. The tread with wide area and coarse grain will cause friction between the snowmobile and the surface, thus providing greater grip for the snowmobile.
Most snowmobiles have added pointed bolts on their belts, which act as wedges on sports shoes. The wedges will slightly penetrate into ice or hard snow, and cut some small holes on the surface to ensure that the belts can stick to the ice more tightly in particularly smooth places. The driver can turn the snowmobile by turning the handle, which is the same as steering a bicycle or motorcycle. The handle is connected with a connecting rod near the front end of the snowmobile, and the connecting rod is connected with a snowboard mounted on the bottom bracket of the snowmobile. When you turn the handle, you will turn the snowboard in the same direction. The width and size of snowboards vary with the terrain. Snowboards can be divided into single-track snowboards and double-track snowboards. Wider snowboards will shift the weight of snowmobiles to a larger range, thus "floating" higher from the snow surface, while narrower snowboards are used for rapid steering. Shock absorbers play an important role in providing comfortable and stable driving experience. The use of springs and dampers is similar to that in mountain bikes, so that riders can use the mobility of snowboards and the stability of belted vehicles to drive their vehicles.
