Abstract
A hollow-shaft arrangement for a motor vehicle includes an inner hollow shaft and an outer hollow shaft. An inner shaft shoulder of the outer hollow shaft is arranged behind the inner toothing in an axial direction as viewed from the inflow end of the inner hollow shaft, the inner diameter (D) of which shaft shoulder is smaller than a root-circle diameter (D) of the inner toothing, so that, when the hollow shafts rotate, the fluid exiting from the outflow end of the inner hollow shaft at least partially is backed up by the shaft shoulder in a tooth root region of the inner toothing and flows back in the direction of the inflow end of the inner hollow shaft within the splice toothing.
