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: A concrete saw includes a generally rectangular frame having a front end, a rear end and a longitudinal length. An engine is supported by the frame. The engine includes a rotational output shaft aligned generally transverse to the longitudinal length of the frame. A saw blade is rotatably connected to the frame and driven by the output shaft of the engine. A cooling system is mounted to a front part of the engine. The cooling system includes a radiator and a cooling fan. The cooling fan is driven by a fan drive assembly having a drive shaft configured as a power take-off to be continuously driven by the engine.
Abstract: A power take off coupling for connecting an engine (20, 21) to a site accessory (16, 14, 17), comprises a resilient power transmission component (3) within the coupling; a latching device (8, 46, 9) to mechanically latch the accessory to the engine (20, 21), with a manually operable release handle (13) to effect unlatching. A power output shaft of the engine (20, 21) carries one half (5) of a dog clutch with the other half (7) carried by the accessory (16, 14, 17).
Abstract: An automatic transmission (1) presents a hydrodynamic converter (3). Consequently, the automatic transmission (1) has a drive region (2) and a driven region (4). The power is split into at least two power branches in the drive region (2). A power branch runs across the hydrodynamic converter (3), another runs parallel thereto. Said at least two power branches are united in the driven region (4). According to the invention, one electrical machine (5) is additionally coupled with the driven region (4).
Abstract: A gearbox arrangement comprising a main gearbox portion, a first gearbox section, and a second gearbox section. The first gearbox section comprises a differential assembly, wherein the differential assembly comprises a ring gear. The ring gear rotates about an axis. The second gearbox section comprises a power take-off assembly and a bearing plate defined by a plane. The axis and plane are parallel to one another. The gearbox arrangement further comprises a separator mounted to at least one of the first and second gearbox sections. Further, a guide is contained within at least one of the first and second gearbox sections.

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.
Abstract: A linkage system is provided which is equipped with a compact and high-rigidity link mechanism with a large load capacity. The linkage system includes three or more link mechanisms. 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 modularly designed mechanical or pressure activated power coupling and complete disconnect assembly independently mounted or directly coupled to a bell housing mount on a drive engine or powered side equipment has provisions for coupling the driveline power via an integrated torsional coupling, drive plate or other mechanism to the rotating member, engine, and powered side equipment.
Abstract: A transmission for a vehicle is proposed which comprises one main transmission MT with one input shaft (1) and one output shaft (2), the same as at least one range change group (3) and one power take off, wherein one countershaft (5) integrated in the range change group (3) for actuating a power take off, the countershaft (5) being connectable, via a gear change sleeve unit (6), with the input shaft (1) and the output shaft (2) and the power take off can be driven independently of the operating state of the vehicle.
Abstract: A tractor includes a frame, an engine, a transmission for selecting a number of vehicle speeds, and a device for transmitting power from the engine to a PTO mechanism. The tractor has a mechanism forming part of the device by which the tractor speed can be selected to be higher than any speed selectable by means of the transmission.
Abstract: An extended shaft for connecting a standard, transmission mounted power take-off device to an auxiliary device which permits non-interference mounting configurations of the auxiliary device to the power take-off device. The extended shaft further provides mounting bracketry to prevent stresses when thermal expansion or contraction of relevant parts occurs during the operation of the motor vehicle or power take-off device.
Abstract: An actuator for engaging and disengaging parts together which, during actuation may incur an obstacle to engagement, the actuator including a mechanism for incurring the obstacle and automatically stopping actuation, a mechanism for removing the obstacle to engagement and for automatically restarting actuation upon removal of the obstacle thereby to achieve engagement.

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.
