Abstract (en)
[origin: WO2009068126A2] The aim of the invention is to provide an especially light-weight main shaft or countershaft for a transmission. The transmission of high torques, such as is the case for the main shaft or countershaft of a transmission, is problematic when the base of the shaft consists of a fiber composite material. A metal element (20, 22) is laminated into the base, a gear (28, 30) being force-lockable with the metal element (20, 22) in such a manner that high torques can be transmitted.
