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.

Abstract: A hydraulic system is provided for a hydraulic shifter assembly of a split shaft assembly having a power take off system and utilized on a vehicle that has an automatic transmission and limited access to the transmission—preventing a direct connection of a power take off to the transmission. The hydraulic system provides hydraulic pressure from the transmission to the hydraulic shifter assembly and back to the transmission from the hydraulic shifter assembly. The system also provides hydraulic pressure from the transmission to the power take off.

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).

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.

Each link mechanism consists of a center link member and end link members rotatably coupled to the center link member and to link hubs that are provided to an input member and an output member, respectively. An input side and an output side of a center cross-sectional plane of each link mechanism are geometrically identical. One or more of revolute joints of two or more of the link mechanisms that are coupled to the input member are provided with a stopping mechanism for stopping the output member at a given position.

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.
