rotationally fixedly and axially fixedly connected to the primary shaft 10 the primary shaft 10 is supported at the housing 14 of the transfer case by means of two roller element bearings 16 and is sealed in a customary manner the roller element bearings 16 are designed as radial ball bearings and include an inner ring 26 an outer ring 28 as well as a set of balls 27 which are arranged therebetween and which can be held by a ball cage not shown as can be recognized the roller element bearings 16 are not in any connection with the ramp ring mechanism fig2 shows a sectional view of a transfer case in accordance with the present disclosure which has a similar structure to the transfer case in accordance with fig1 as can be recognized the roller element bearing 16 u2032 disposed at the right in the figure is here however made as a tapered roller bearing and is thus able to receive both axial and radial forces in accordance with the representation the roller element bearing 16 u2032 is supported in the housing 14 so that an axial force reception against the adjustment direction v of the adjustment ring 49 is made possible as is shown the tapered roller bearing 16 u2032 is supported by means of its outer ring 28 radially in a bearing section 38 of the housing 14 with a section 30 of the peripheral surface of the outer ring 28 facing the friction clutch 12 being exposed the inner ring 26 of the tapered roller bearing 16 u2032 is seated.
