A device for driving a pair of output shafts (19, 20) from a common rotary input shaft (2) and for permitting differential rotation of the output shafts relative, to each other. The device comprises means (3, 4) for coupling the input shaft to a ring gear (6) so that the ring gear is rotated in response to rotation of the input shaft, and two planetary gear sets (9, 10) each in mesh with the ring gear and each having a respective planetary gear carrier (7, 8) for driving connection with a respective one of the output shafts. Each planetary gear set has a respective sun gear (11a, 12a) and means (11, 12, 31, 33) are provided for rotating one sun gear relative to the other sun gear to produce differential rotation of the output shafts. |
