ABSTRACT:
A driving and steering mechanism of a track-laying vehicle comprises a drive motor, which has a motor shaft that is parallel to and extends beside the vertical longitudinal center plane of the vehicle, a shiftable transmission, which operatively connects said shaft to a power train, which comprises an angle drive and a universal-joint shaft, two planetary spur gear trains for driving respective propelling wheels of the vehicle and adapted to be driven by said power train, and a controllable hydrostatic transmission, which is operatively connected to said drive motor and arranged to rotate two gear members of respective ones of said planetary spur gear trains in mutually opposite senses. The drive motor, the shiftable transmission and the angle drive of the power train are aligned in the axial direction of the motor shaft and are directly connected to each other and adjoin each other, the universal-joint shaft of the power train extends transversely to said direction and is surrounded by a tubular shaft and is non-rotatably connected at one end to the angle drive and at the other end to the tubular shaft, the tubular shaft carries two gears, which mesh with respective gear members of respective ones of said planetary spur gear trains, and the pump of the hydrostatic transmission is directly driven by an auxiliary shaft of the shiftable transmission.
