Abstract

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, via a bevel gear 46b or via an arrangement of spur gears (26,27 fig 2). The planet carriers 54,55 are interconnected by a shaft 43 such that they rotate in common. An output shaft 50,51 is coupled to each annulus 48,49. The device is suitable for determining the skid steer action of a vehicle having electric motors 52,53 adjacent to driven wheels or track sprockets.
