ABSTRACT:
Differential transmission with a rigid support ring (1) which exhibits an essentially cylindrical bearing surface (2) and with a radially flexible roller bushing (5) which has an outer surface (7) with a circumference smaller than the bearing surface (2), wherein one or more circumference segments of the outer surface (7) are maintained in essentially slip-free engagement with the bearing surface (2) of the support ring (1) via multiple transmission elements (32), said engagement progressively successively changeable by rotation of a drive core (20) rotatably provided within the roller bushing (5) and rotatably driven by a drive shaft (14), wherein the transmission elements (32) are formed by a multitude of essentially radially extending segments of equal length, that the roller bushing is supported upon the drive core (20) via these segments, and that the segments with their radial side surfaces lie against each other and with respect to each other are radially slidable.
