摘要： The invention provides a gearing apparatus (4) comprising a gearing assembly (5) comprising a rotary input member (1b), a rotary output member (3) and a gearing arrangement between the input member (1b) and the output member (3) selectively engageable to effect a driving engagement between the input member (1b) and the output member (3) through at least a first torque connection having a first gear ratio and a second torque connection having a second gear ratio. The gearing apparatus further comprises a shift arrangement (6) for shifting the gearing arrangement between a first state in which there is driving engagement between the input member (1b) and the output member (3) through the first torque connection and a second state in which the gearing arrangement does not provide driving engagement between the input member (1b) and the output member (3) through the first torque connection. The shift arrangement (6) comprises at least one shift stick (62) for acting on the gearing assembly (5) for shifting the gearing arrangement between at least the first state and the second state, wherein one of the rotary input member (1b) and the rotary output member (3) comprises a first shaft and the at least one shift stick (62) is carried in a slot (33) extending axially in the outer surface of the first shaft and arranged for axial movement therewithin relative to the first shaft for acting on the gearing assembly (5) in shifting the gearing arrangement between the first state and the second state.

摘要： A controlled differential device comprises a pair of epicyclical gear trains each comprising a sun gear (44,45), planet carrier (54,55) and annulus (48,49). The sun gears are rotated in mutually opposite senses by a motor (41), the planet carriers are interconnected by a shaft (43) such that they rotate in common, and output shafts (50,51) are coupled to the annuli. Also disclosed are drive configurations for a skid steered vehicle incorporating the controlled differential device.
