Abstract:
Differential transmission with a rigid support ring (1) which exhibits an essentially cylindrical bearing surface (2) and with a radially flexible roller bushing (55) 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 (52), said engagement progressively successively changeable by rotation of a drive core (50) rotatably provided within the roller bushing (55) and rotatably driven by a drive shaft (14), wherein,the transmission elements (52) are formed by a multitude of essentially radially extending segments of equal length, wherein the roller bushing is supported upon the drive core (50) via these segments, and wherein the segments lie against each other with their radial outside surfaces and are radially slidable with respect to each other.
