ABSTRACT:
An epicyclic steering differential for use with a vehicle that is driven by tracks provides steering control and differential action to the vehicle by way of a set of differential cluster gears disposed about the pitch circle of the control gears with which the cluster set mates, engaging concurrently each of two adjacent cluster gears of the set, and driving two oppositely disposed drive gears that ultimately transmit power to the tracks. Each cluster gear has a pitch diameter equal in size to that of the control gears. The clusters are arrayed about the control gears so that the pitch diameter of adjacent clusters are mutually tangent and tangent also with the control gear pitch circle. In this way cluster gear transmits power at two points of meshing contact.
