  • Patent number: 7757580
    Abstract: An actuating device for vehicle transmissions, in particular of tracked vehicles or wheeled vehicles having a wheel-based steering system, for the remote shifting and emergency shifting of the vehicle transmission is disclosed. The actuating device has a signal transmitter for the driving direction of the vehicle. A single lever is provided for actuating the remote shifting for the driving direction and the emergency shifting and for producing a driving-direction signal.

  • Patent number: 7621354
    Abstract: A drive system for a tracked vehicle having an internal combustion engine with a crankshaft aligned transversely to a direction of travel includes a steering drive; a differential transmission having traction drive elements, steering drive elements, and a pair of drive outputs for a drive axle aligned parallel to the crankshaft; and a steering drive connection connecting the steering drive to the steering drive elements. A further drive element, which may be a change speed gearbox or an electric traction motor, is arranged in line with the internal combustion engine and transmits power to the traction drive elements.

  • Patent number: 7201691
    Abstract: A superposition steering system for tracklaying or wheeled vehicles with nonpivoting wheels with a drive system (1) and a zero shaft (10, 10?) to transfer the drive power from one drive side to the other, via at least one steering differential gear (9), wherein the zero shaft (10, 10?) can be driven from a power fraction branched off from the drive system (1) and at least one electric motor (2, 2?).
