A herringbone reinforcing beam 4 is fixed between the edge beam 5 and the middle cross beam 2. A herringbone reinforcing beam 4 is fixed between every two adjacent middle cross beams 2.

The planetary gear assembly 8 includes a transfer case unit having a single stage planetary gear transmission and a differential including a two-stage planetary gear transmission having a planetary gear set. The planetary gear is connected by a planetary gear pin, which comprises two pin elements connected by a joint connection. For this purpose, a bore, which is a blind bore, is formed in the end face of the pin element having the outer diameter D, into which bore a further pin element having the outer diameter D is fitted. In addition or alternatively, an integral connection to the pin element is provided in addition to the form-locking and force-locking press fit. In the installed state, the planet pin is locked in a rotationally fixed and positionally fixed manner, in particular by means of a targeted caulking, in the receptacles of the different carrier sections of the planetary gear, which receptacles are embodied as holes or mating holes.
