ABSTRACT:
A countershaft-type transmission device has an input central shaft and an input hollow shaft and two powershift elements. One first half of the powershift elements is in connection with one drive unit and a second half of the powershift elements is connected with the input central shaft or the input hollow shaft. The input central shaft, the input hollow shaft and countershafts are supported in one housing and connected with gear wheels, which are engaged with each other by pairs and can be connected and disconnected to produce a transmission total ratio in the power flow. The input central shaft is supported in the housing via a first bearing device and the drive unit is supported via a second bearing device on a shaft connected with a drive unit, the input hollow shaft being supported on the input central shaft via a third bearing device and a fourth bearing device.
