摘要： 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.

摘要： 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.

摘要： The compact, all-gear full-traction differential includes meshing pairs of side-gear worms and worm-wheel balance gears having a “hybrid” design. Preferably, the teeth of each side-gear worm have an involute profile but are cut with only plunge feed, while the teeth of the worm-wheel portions of the balance gears are helicoid worms having tip and root modifications made by a convex-shaped cutter. The side-gear worm teeth have a helix angle equal to or greater than 45° and significantly chamfered ends, and the gears are designed to provide a gear ratio between 1.5:1 and 2.5:1. The numbers of teeth in the spur-gear portion and worm-wheel portion of each balance gear and in each side-gear worm are all divisible by 2 or by 3, preferably by both 2 and 3.

摘要： The transmission includes an orbital gear complex in combination with a variable hydraulic pump and motor. The input to the transmission is increased in speed by the orbital gearing such that, when the pump and motor are not operating, the orbiter is stationary, and the orbital gearing produces an overdrive condition. A gear reduction is accomplished by rotating the web with the web-rotating device, providing a high gear reduction. The pump and motor are preferably long-piston hydraulic machines with infinitely variable swash plates. The hydraulic machines preferably have wobblers stabilized by full gimbals and hold-down plates with elongated holes for the long pistons to eliminate possible impacts between the hold-down plates and the head ends of the long pistons when the swash-plates are at or near their maximum angle of inclination.
