  • Electrohydraulic control system for controlling gearspeed changes in partially or fully automatic transmissions of vehicles
    Patent number: 6659899
    Abstract: A control unit has a signal input from at least one sensor and a signal output for electrically actuating at least one valve in order to hydraulically activate a gear-changing element. An emergency gear change slide can switch off the electrical actuation of the valves so that hydraulic modulation can be carried out.
    Type: Grant

  • Electromechanical drive for track-laying vehicles
    Patent number: RE39179
    Abstract: An electromechanical drive for track-laying vehicles in which the two drive sides have no mechanical coupling and permits smaller overall lengths and overall diameters. As a result, the flexibility of the arrangement of the drive components compared is further increased. The drive includes an electric traction motor, at least one variable-speed mechanical gear unit, and at least one brake. At least one of these components is arranged inside the rotor of the electric motor, and the remaining components are arranged laterally at the electric motor in such a way as to lie coaxially in approximately one plane.
