The invention is about a crawler driving device, which includes a main frame (10), a rotary driving wheel (20) set over the main frame (10), idler wheels (30) arranged at both ends of the main frame (10), as well as multiple interval roller wheels (40) mounted at the bottom of the main frame (10) in the driving direction, and tracks(50) sleeved on the outside of the drive wheels (20), the idler wheels (30) and the roller wheels (40). The driving wheel (20) of the current invention and the teeth (51) inside the track belt (50) are in meshing structure, so as to drive the track belt (50) to rotate. The roller wheels (40) at the bottom can swing up and down during the driving, and supporting the system as well. The roller wheels (40) swing up and down with a rotating shaft (32) in the middle of mechanical balancers (41). In case of uneven terrain, the four sets of roller wheels (40) at the both ends of the balancer (41) can be force-buffered at the same time, so as to ensure a stable ground drive and keep the vehicle moving smoothly. The idler wheels (30) guide direction, and a tensioning mechanism (60) provides a tension adjustment between the track (50) over a the front idler wheel (301) under the action of a hydro-cylinder (61).
