Description

technical field [0001] The invention relates to a special off-road vehicle, in particular to a tracked all-terrain vehicle. Background technique [0002] Tracked all-terrain vehicle is a high-speed special vehicle used in mountains, snow, swamps, river beaches, deserts, ravines and other terrains. It mainly has two forms: single body and double body. The crawler-type double-body all-terrain vehicle is composed of a front body and a rear body articulated with it through a five-free-direction articulated steering device; although the structure is relatively simple, since the engine is usually installed on the front body, the vibration , noise and high temperature have a greater impact on drivers and passengers, and the driving comfort is poor. In addition, since the rear car body is not equipped with a power unit, it is driven by the front car body; therefore, the mobility, off-road performance, driving force, etc. of the whole vehicle are not ideal. The 3rd, because of the ...
