ABSTRACT:
A transfer case (10) having a drive shaft (12) on a bearing (18) to permit the drive shaft to be rotated with respect to the transfer case, the drive shaft having a free end portion (12a) which is adapted to drive an axle of a vehicle. The drive shaft passes through a sleeve (20), and bearings (22, 24) are provided to permit the sleeve to be rotated with respect to the transfer case. The sleeve has a sprocket (14) affixed to it, and the sprocket is caused to rotate by an endless chain (16). The sleeve is drivingly connected to the drive shaft by a universal joint (26), preferably a cardan joint, which is contained within an enlarged end portion (20a) of the sleeve. The sprocket is positioned between the universal joint and the free end portion of the drive shaft, to maximize the distance therebetween, and thereby minimize the included angle required of the universal joint.
