A main shaft for a transmission or a countershaft for a transmission shall be constructed in an especially light-weight manner. The transmission of high torques, such as is the case for the main shaft or countershaft for a transmission, is problematic when the base body of the shaft consists of a fiber composite material. A metal element () is now laminated into the base body, and a gearwheel () can then be connected to this metal element () in a force-fit manner, so that high torques can be transmitted.

Main shaft for a transmission or countershaft for a transmission

In a dual clutch transmission with a main group and final shift group, with a coupling device for coupling a transmission element of the main group to a final shift group transmission element of the final shift group, the transmission comprises two transmission gears (VL, VL, VH, VH) which can be formed simultaneously with one of the transmission gears (VL, VL) assignable to a lower group of the final shift group and another of the transmission gears (VH, VH) assignable to an upper group of the final shift group.
