ABSTRACT:
This invention relates to a track unit intended for endless tracked cross-country vehicles, for example forestry working machines, comprising at least one driven track driven from a driven axle of the vehicle. In order to render possible the driving of forestry working machines with tracks of rubber, which are much more sparing for the ground than steel tracks, but do not possess the tensile strength of steel tracks, the present track unit of bogie type distributes the driving force on several tracks and comprises two track stands (9), each of which comprises a track (8) supported on two wheels (38,39) and driven via of these wheels (38,39), which track stands (9) are mounted between the axles (40,41) of their wheels each at one end of a rocker arm (5), which in its turn is located freely pivotally between its ends on the drive axle (4) of the vehicle, between which drive axle and the drive wheel axle (40) of each track stand a chain transmission (12,13,14,37) is located.
