  • Patent number: 8863617
    Abstract: A motor vehicle transmission having an input shaft, which can be coupled to a drive aggregate, an output shaft, which can be coupled to an output, and several shift elements. At least two shift elements, designed as clutches, are each coupled via an outer clutch plate carrier with the input shaft in such a way that an outer clutch plate carrier of a first radially outer clutch encloses an outer clutch plate carrier of a second radially inner clutch at least sectionally and radially outside. A drive gear is coupled to the input shaft through which a power take-off can be coupled to withdraw power from the input shaft or through which an auxiliary drive aggregate can supply power to the input shaft. The drive gear is linked through the outer clutch plate carrier of the radially inner clutch to the input shaft.

  • Patent number: 7584040
    Abstract: The following steps are performed in the control method: determining a mode of operation from amongst a permanent mode and a transient mode, as a function of a set of variables comprising said estimated values; correcting the value of the speed of rotation of the outlet shaft in such a manner that: if the mode has been determined as being the permanent mode, then the moving average (L?) of the gear ratio (L) over a period (T) of a plurality of unit time intervals lies between a first threshold value (S1) that is negative and a second threshold value (S2) that is positive; and if the mode has been determined as being the transient mode, then said moving average (L?) of the gear ratio (L) lies outside the range of values defined by the first and second threshold value (S1, S2).

  • Publication number: 20080128193
    Abstract: A fluid drive system for vertical mixer tubs is provided. Rotational power from the power take-off of a tractor or other suitable vehicle is increased in rotational speed by an input gearbox. The input gearbox is, in turn, coupled to a fluid coupler that locks up when the input rotational speed reaches an optimum speed. The output of the fluid coupler is coupled to an output gearbox that reduces the rotational speed of the fluid coupler. The output of the output gearbox is connected to the drive mechanism of the mixer tub auger.

  • Patent number: 6173225
    Abstract: A control system is disclosed for controlling a power takeoff (PTO) shaft of a work vehicle (e.g., a tractor). The work vehicle includes an engine and an operator station, and the PTO shaft transfers power from the engine to an implement. The control system includes a remote switch, a vehicle speed sensor, and a control circuit. The remote switch is located remotely from the operator station and provides a remote switch signal to the control circuit to engage and disengage rotational movement of the PTO shaft. The vehicle speed sensor provides a vehicle speed signal to the control circuit representative of a speed of the work vehicle. The control circuit receives the remote switch signal and the vehicle speed signal and, when the vehicle speed signal exceeds a predetermined vehicle speed, the control circuit prevents engagement and disengagement of the PTO shaft with the remote switch.
