摘要： 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.

摘要： An agricultural machine transmission has a powershiftable main group arranged upstream or downstream of a powershiftable split group in the direction of force transfer. The split group has an input shaft, an output shaft, and powershift elements, which when selectively actuated permit configurations of at least six different forward gears and at least three different reverse gears between the input shaft and the output shaft of the split group. A driveshaft of the main group is connectable by a first powershift clutch to a first input shaft and is connectable by a second powershift clutch to a second input shaft of the main group. Spur gear stages of the main group can be integrated into the force transfer path by actuating an associated shift element, coupling an associated input shaft to the drive shaft of the main group by configuring a respective gear of the main group.

摘要： A powershift transmission has a split group with a plurality of powershift stages and an input shaft that can be rotatably driven by a drive shaft of a motorized drive. The input shaft transmits in a stepped-up manner to an output shaft of the split group a rotational movement corresponding to a selected powershiftable stage transmission. A synchromesh transmission group has at least four gear stages and can be rotatably driven by the output shaft of the split group via an intermediate group located therebetween, and via the output shaft of the synchromesh transmission group an axle transmission of the motor vehicle can be rotatably driven. The intermediate group has first and second switching elements each having an output shaft that can be coupled by means of a switchable clutch to an idler. First and second output gears are arranged on the output shaft of the synchromesh transmission group.

摘要： A transmission assembly including a torque input shaft and a torque output shaft and input idler gears, input fixed gears and shift elements, each of which is associated with an input idler gear, are arranged on the torque input shaft, and output idler gears, output fixed gears and shift elements, each of which are associated with an output idler gear, are arranged on the torque output shaft, with the result that a plurality of different torque transmission paths from the torque input shaft to the torque output shaft may be implemented. The transmission arrangement has an additional torque transmission path that may be implemented. The additional torque transmission path runs from the torque input shaft through a double gear to the torque output shaft. The transmission assembly can be included in a corresponding overall transmission which can be installed in an agricultural machine.
