Abstract

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 (20, 22) is now laminated into the base body, and a gearwheel (28, 30) can then be connected to this metal element (20, 22) in a force-fit manner, so that high torques can be transmitted.
