The drive constant is connected with an output shaft, which is parallel to the main shaft. The transmission shafts are supported by bearings, which are arranged in bearing planes, one of which is formed by an inner wall of the transmission housing and is axially adjacent the drive constant. This bearing plane includes one bearing supporting the main shaft, one bearing supporting the second input shaft and one bearing supporting the first input shaft within the second input shaft.
