Two-stage power branching planetary transmission wheel drive having an inner planetary gear set and an outer planetary gear set. The inner planetary gear set has its planetary carrier loosely splined to a fixed support or hollow spindle of the wheel drive while its gear ring is splined to the gear ring of the outer planetary gear set the planetary carrier of which is, in turn, splined to the sun gear of the inner planetary gear set, roller type antifriction wheel bearings which journal the wheel hub of the assembly being both supported by the torque support or reaction element of the drive.
