The invention is about a crawler driving device, which includes a main frame, a rotary driving wheel designs over the main frame, idler wheels design at both ends of the main frame, as well as multi-pair interval roller wheels mounted at the bottom of the main frame for fore-after driving direction, and crawlers sleeved on the outside of the drive wheels, the idler wheels and the roller sets. The driving wheel of the current invention and the tooth block inside the crawler belt are in meshing structure, so as to drive the crawler belt to rotate. The roller wheels at the bottom can swing up and down during the driving, and supporting the system as well. the roller wheels swing up and down with the rotating shaft in the middle of the mechanical balancers as the fulcrum. In case of uneven terrain, the four sets of roller wheels at the both ends of the balancer can be force-buffered at the same time, so as to ensure the stable ground drive and keeping the vehicle smoothly moving. The idler wheels guide direction, and the tensioning mechanism realizing the tension adjustment between the track and the wheel under the action of the hydro-cylinder.
