A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.

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 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 embodiment hybrid powertrain for a vehicle includes a first input shaft configured to be interlocked with an engine, a second input shaft configured to be interlocked with a first motor and to be parallel to the first input shaft, a third input shaft configured to be interlocked with a second motor and to be parallel to the second input shaft, an output shaft mounted parallel to the third input shaft, a first selective mesh device configured to transmit power from the second input shaft to the output shaft at multiple different gear ratios, a second selective mesh device configured to transmit the power from the third input shaft to the output shaft at the multiple different gear ratios, and a third selective mesh device configured to transmit the power from the first input shaft to the second input shaft or the third input shaft.

A coupling arrangement for coupling members as a gear change coupling in a gear mechanism unit includes a first member and a second member. The first member has a coupling toothing system. At least one locking body arrangement is mounted pivotably on the second member. The locking body arrangement can be pivoted into a coupling position, in the case of which a driving section on the locking body arrangement engages into the coupling toothing system. The locking body arrangement can be pivoted into a release position, in the case of which the driving section of the locking body arrangement does not engage into the coupling toothing system. The locking body arrangement has a locking body carrier which is mounted pivotably on the second member, and has a locking body member which is mounted pivotably on the locking body carrier and on which the driving section is configured.

A transmission includes a drive element, a first output element, a primary transmission unit, a reversing unit, and an intermediate gearbox. At least three of the at least eight shifting elements of the primary transmission unit, at least one of the at least two shifting elements of the reversing unit, and at least one of the at least two shifting elements of the intermediate gearbox are activatable in combinations of at least five shifting elements so as to establish at least twenty-eight forward gears between the drive element and the first output element.

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.
