  • Patent number: 10443710
    Abstract: A drive-train of a vehicle which at least includes a drive motor (1) and a transmission (2). The drive-train has at least one torque sensor (6, 6A) which is provided for the purpose of controlling a drive component of the drive-train. The torque sensor (6, 6A) is integrated in a transmission component in order to determine, at the time, the torque applied to the transmission component.
    Type: Grant

  • Patent number: 8290667
    Abstract: A method for the operation of a traveling power take-off shaft clutch connected to a drive motor, in a case of known wheel or vehicle speed, the speed of rotation of the power take-off shaft, electronically evaluated through the speed of rotation of the motor, can be made to agree in ratio with the wheel speed.

  • Patent number: 8065062
    Abstract: To eliminate the need for additional operating elements for fine tuning the management of the engine and transmission of a mobile agricultural vehicle, the electronic transmission-control unit is connected via an ISO bus to the ISO bus terminal, such that current transmission data can be displayed in the cabin of the vehicle and adjustments can be made via the ISO bus terminal to modify this transmission data.

  • Patent number: 8047941
    Abstract: A drive unit (1) for continuously, variably controlling rotational speed and reversing the rotational direction of at least one output shaft. The drive unit (1) having two identical transmission modules (2, 3) with a common input (4) and a way for power splitting a continuously variable rotational speed and reversing the rotational direction.

  • Patent number: 7631494
    Abstract: A hydrostatic transmission of a hydrostatic-mechanical power distribution transmission in which the high-pressure limiting valves in the hydrostatic transmission are eliminated or adjusted to enable a working pressure higher than the working pressure on which the maximum pressure is based. For short time intervals, a pressure substantially higher than the pressure on which the maximum pressure is based under constant load of the hydrostatic transmission, can be adjusted. The hydrostatic transmission has high-pressure sensors connected with the control of the hydrostatic-mechanical power distribution transmission.

  • Patent number: 6578450
    Abstract: A power-splitting transmission which consists of a hydraulic power branch (7) and a mechanical power branch. Leakage in the hydraulic power branch (7) as well as the activation apparatuses (12) in the mechanical power branch are supplied with a pressurized medium from a common pressure source (1). The common pressure source (1) transports pressure medium to the hydraulic power branch (7), through a damping apparatus (3), and simultaneously transports pressure medium to the activation apparatuses (12) of the shifting elements (13) of the mechanical power branch via a controller (11).
