Shifting device for shifting a transmission, having a first group of shift elements and a second group of shift elements, a selector shaft, which is arranged in such a way that it can be moved in translation along a longitudinal axis and rotated about the longitudinal axis, wherein it is possible, by moving the selector shaft into one of a plurality of possible translational positions, to select at least one shift element of the first group and at least one shift element of the second group and, by rotating the selector shaft, to actuate the selected shift elements. The at least one selected shift element of the first group can be actuated in phase or with an overlapping phase displacement or an offset phase displacement with respect to the at least one selected shift element of the second group.

A transmission device for a work vehicle includes an auxiliary transmission including forward gear shift stages for the work vehicle to move forward and a reverse gear shift stage for the work vehicle to move backward. The forward gear shift stages include a low-speed gear shift stage with a largest gear ratio among the plurality of forward gear shift stages, and a medium-speed gear shift stage with a gear ratio closest to a gear ratio of the reverse gear shift stage among the forward gear shift stages.

An actuation device for a motor vehicle having a transmission with gear steps and a friction clutch for automated actuation of both the transmission and the friction clutch, where the actuation device has an actuator device with whose help both a rotational movement and a translational movement is executable, in order to improve the actuation device in terms of construction and/or function.

The invention is to suppress the increase of axial lengths of each input shaft and each output shaft and increase the number of gear shift stages. A transmission device transmits a driving force of a crankshaft from a first transmission to a drive wheel side through a second transmission. The first transmission is provided with a first countershaft to which the driving force from the crankshaft is transmitted, and a first drive shaft to which the driving force of the first countershaft is transmitted. The second transmission is provided with a second countershaft to which the driving force of the first drive shaft is transmitted, and a second drive shaft to which the driving force of the second countershaft is transmitted and which transmits the driving force to the drive wheel side. The first and second transmissions are disposed side by side in a front/rear direction. Each of the first and second transmissions is set to have a plurality of gear shift stages.
