NO-SLIP, IMPOSED DIFFERENTIAL

摘要

A no-slip, imposed differential uses a first unlimited slip differential (15) connected for driving a pair of axle shafts (16) and (17) and a second unlimited slip differential (20) connected between a pair of control shafts (22) and (23). One of the axle shafts and one of the control shafts are connected for rotation in the same direction, and the other axle shaft and the other control shaft are connected for rotation in opposite directions. An input control gear (40) meshed with a ring gear (21) for second differential (20) can rotate control shafts (22) and (23) to impose differential rotation on axle shafts (16) and (17) via the shaft connecting means. This provides a no-slip drive when control gear (40) is not turning and a steering drive by imposed differential rotation when control gear (40) turns.
