The differential steering drive for a tracked vehicle includes a drive differential interconnecting the drive shafts for the tracks and a steering differential for superimposing additive and subtractive rotations to the tracks for steering and pivot turning. In the preferred embodiment for high speed tracked vehicles, the drive differential is an all-gear no-clutch type limited-slip differential, and the steering differential is an unlimited-slip differential. The differentials are arranged to provide no-slip track operation traveling in straight paths or when steering so long as at least one track has traction. In another embodiment for pivot-turning slow-moving off-road vehicles, both the drive differential and the steering differential are all-gear no-clutch type limited-slip differentials. Further, both embodiments preferably include an additional left-side and an additional right-side all-gear no-clutch type limited-slip differential for dividing the torque delivered to a respective pair of drive axles associated with each track.

The differential steering drive for a vehicle includes a drive differential and a steering differential. The vehicle includes respective left and right driving traction elements, a propulsion engine with an engine crankshaft, and a steering wheel rotatable by an operator to indicate an intended direction of travel. At least one of the drive differential and the steering differential includes an all-gear limited slip differential. In another embodiment, both the drive differential and the steering differential include an all-gear limited slip differential.

In the basic embodiment, the transmission includes (a) a minimal-orbiter gear complex having only a control gear and an output gear interconnected by the gearing portions of at least one cluster gear supported by an orbiting web responsive to an input drive provided by a primary engine and (b) a single, infinitely-variable rotary control device providing resistance torque to counter engine torque to slow and stop the control gear of the orbital complex. The rotary control device, which may be a hydraulic jack or an electrically braked magnetic wheel, provides no propelling motion but rather only provides a resistive torque. In a preferred embodiment for automotive use, the engine torque is split at all times between two mechanical paths. One path drives the web of a minimal orbiter gear set, and the other drives the sun gear of a single, standard planetary gear set.

The transmission includes a minimal-orbiter gear complex and a single infinitely-variable rotary control device. The minimal orbiter includes only a control gear and an output gear interconnected by the different gearing portions of at least one cluster gear supported by an orbiting web responsive to an input drive provided by a primary engine. The rotary control device may be any kind of apparatus that is capable of providing resistance torque that can match the torque of the primary engine to slow and stop the control gear of the orbital complex. In a preferred embodiment disclosed, the rotary control device is a hydraulic jack machine having a drive shaft connected to an adjustable swash plate that provides primary control of the flow of fluid through the machine.
