The transmission includes a first shaft, a second shaft, a third shaft, and a fourth shaft. These shafts are parallel to each other. A first gear couples to the first shaft. A second gear couples to or idles around the first shaft when a first clutch is switched. A third gear meshes with the first gear and couples to the second shaft. A fourth gear couples to or idles around the second shaft when a second clutch is switched. A sixth gear meshes with the first gear and couples to the third shaft. A seventh gear couples to or idles around the third shaft when a fourth clutch is switched. A ninth gear meshes with the second gear, the fourth gear, and the seventh gear, and couples to the fourth shaft.

A propulsion system for an electric vehicle includes an assembly of four electric propulsion machines each having a stator and a rotor having an output shaft that is movable in rotation about an axis. Also includes is a common gearwheel that is kinematically connected to the n output shafts and that is able to receive the torque provided by the electric machines so as to form a first speed reducer, and primary gearwheels able to be driven by the common gearwheel. An intermediate shaft is able to be driven by intermediate gearwheels, each primary gearwheel being kinematically connected to a corresponding intermediate gearwheel so as to form a pair of gears with which a second speed reducer is associated, and a secondary shaft that is able to drive the vehicle and that has a secondary gearwheel kinematically connected to the intermediate shaft so as to form a third speed reducer.

A powershift transmission for an agricultural machine includes a transmission housing, an input shaft and an output shaft unit. The input shaft and the output shaft unit extend at least at a distance within the transmission housing. The transmission also includes an auxiliary shaft arranged within the transmission housing and offset between the input shaft and the output shaft unit. The input shaft and the auxiliary shaft are connected to one another via a front-mounted range unit, and the auxiliary shaft and the output shaft unit are connected to one another via a rear-mounted range unit. Each range unit includes at least two individual gear wheel pairs which are coupled or decoupled. The output shaft unit includes a main output shaft and an auxiliary output shaft coupled to one another via a reduction gear unit.

An electric drive axle of a vehicle includes an electric motor having an output shaft. An idler assembly is drivingly coupled to the electric motor and a differential.

The transmission system also includes a module housing, a first output shaft rotatably coupled to the countershaft, and a second output shaft rotatably coupled to the countershaft. The transmission system further includes a first clutch configured to selectively rotatably couple the first output shaft to the countershaft. The transmission system also includes a second clutch configured to selectively rotatably couple the second output shaft to the countershaft. The transmission system further includes an electric machine configured to deliver rotational power to at least one of the first and second output shafts to deliver rotational power to the countershaft. The countershaft is rotatably coupled to either of the first and second output shafts for all of the gear ratios.

A work vehicle transmission includes a first transmission mechanism that changes input motive power to any one of multiple speeds, and a second transmission mechanism that changes the motive power changed by the first transmission mechanism to any one of multiple speeds, the number of speeds of the second transmission mechanism being smaller than that of the first transmission mechanism. Multiple speed change multi-disc clutches of the first transmission mechanism are arranged parallel with multiple deceleration multi-disc clutches of the second transmission mechanism so as to be adjacent in the diameter direction thereof.

A method is provided for configuring different numbers of gearshift variants in a stepped powershift transmission for an agricultural working machine. The method includes providing a transmission unit, a front-mounted range unit, a gear reduction unit, a rear-mounted range unit, a housing, a drive shaft, a lay shaft, an output shaft, and a hydraulic control arrangement. The same transmission unit is used for all the numbers of gearshift variants while an identical spatial orientation of the shafts is maintained for all the numbers of gearshift variants. The method further includes adapting exclusively the gearshift variants by varying the front-mounted range unit or the rear-mounted range unit.

A powershift transmission of a motor vehicle has a split group with a plurality of powershift stages. An input shaft can be rotatably driven by a drive shaft of a motorized drive and transmits rotational movement in a stepped-up manner to an output shaft of the split group corresponding to one of several powershiftable stage transmissions. The powershiftable stage transmissions can be rotatably driven in a stepped-up manner by the output shaft of the split group via an intermediate group located therebetween, and via an input shaft of a synchromesh transmission group having a plurality of gear stages. A vehicle axle transmission can be rotatably driven by the output shaft of the synchromesh transmission group. The intermediate group has a multiple powershift intermediate transmission, in which each switching position the input shaft of the synchromesh transmission group can be rotatably driven by means of an associated transmission.

A transmission includes an input assembly, an electric machine, a variator and a power shift assembly. The input assembly has directional clutches and is configured to receive rotational engine power. The variator has only a single planetary set configured to selectively receive rotational power from the electric machine and from the input assembly. The power shift assembly is configured to receive rotational power from the variator. Power shift clutches are configured to dissipate energy from asynchronous gear meshing and include a first power shift clutch carried by a first countershaft and a second power shift clutch carried by a second countershaft. The power shift assembly is configured to effect multiple different rotational power flows to effect unique gear ratios.
