摘要： An all-gear differential designed primarily for motor vehicle use, employing a "cross-axis" arrangement defined by a pair of helical "side" or "S" gears rotatable about a common first axis and mountable on respective opposite vehicle axles, and one or more pairs of "balance" or "B" gears rotatable about second axes orthogonal to the first axis. The B gears have helical central portions for meshing with the helical S gears, and have spur gear end portions for meshing with each other. The B/S helical gear tooth ratio between each balance gear and its respective side gear greater than 0.60 and preferably is about 0.75, and the B/S helical angle ratio between each balance gear and its respective side gear is less than 43°/47°, more preferably is less than 40°/50° and about 35°/55°, and most preferably is about 27°/63°.

摘要： The differential steering drive 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 turning if at least one track has traction. In another embodiment for pivot-turning slow-moving off-road vehicles, both the drive and the steering differential are all-gear no-clutch type limited-slip differentials. Further, both embodiments preferably include additional left- and right-side all-gear no-clutch type limited-slip differentials for dividing the torque delivered to a respective pair of drive axles associated with each track.

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.

摘要： A transmission has only a single, minimal orbiter (12) in which an input gear (20) and an output gear (22), each being connected to separate input and output shafts, are interconnected through an orbiting cluster gear (26) that meshes with only the input and output gears. The cluster gear is carried by a web that is itself rotated by a hydraulic control motor through a first clutch (46). When rotation of the web is prevented, rotation of the input gear produces rotation of the output gear at a predetermined reduction of the input drive, this gear reduction being continuously diminished proportional to the speed of rotation of the web in a first direction. When the vehicle reaches highway speeds, the control motor is disconnected and a second clutch is activated to connect a predetermined overdrive that is located between the engine drive and the transmission rather than being conventionally positioned between the transmission and the final output shaft.

摘要： A modular track suspension system is readily adapted for attachment to any presently manufactured full-size automotive vehicle (10) built with a load-carrying frame (12), being easily substituted for the vehicle's conventional wheeled undercarriage either during or following final assembly. The module uses a pair of endless rubber tracks (14, 15), one track under each respective side of the vehicle; and each track (14, 15) is supported over tandem units (17, 18) with, preferably, side-by-side dual-wheels (20, 21 and 22, 23) having rubber tires. The dual-wheels are each movable in a vertical plane, and each dual-wheel can move separately and independently of the similar independent movement of the other dual-wheel with which it is in tandem. Each dual-wheel is also resiliently biased in the direction of the terrain on which the vehicle is standing or moving.

摘要： The size, weight, and cost of a full-traction differential are significantly reduced by the synergism of several interrelated design features of a cartridge-like gear complex: (1) Each combination gear has only a shallow journal hole in each end of an otherwise solid gear body, being supported on mating hubs fixed to mounting plates slipped into a one-piece differential housing. (2) The solid worm-wheel portion of the combination gears has a deeper hour-glass shape. (3) Mating worm/worm-wheel teeth have a broad "supra-enveloping" contact pattern on only the drive side of the mesh. (4) The side-gear worms have closed-end teeth. (5) Both diameter and axial length of the side-gear worms are reduced by a special cutting process. The efficiency of the differential is increased by a thrust plate supported in the mounting plates and positioned between inner ends of the side-gear worms.

摘要： Smaller and lighter hydraulic pump/motors are provided with pistons having body portions substantially as long as the axial length of the respective cylinders in which they reciprocate. A plurality of respective lubricating channels, formed circumferentially and radially transecting the walls of each cylinder, is each positioned to be closed at all times by the axial cylindrical body of each respective piston during its entire stroke. Each lubricating channel is interconnected, one to another, to form a single, continuous lubricating passageway entirely within the cylinder block and not connected by either fluid "input" or fluid "output" passageways, being replenished solely by blow-by entering from the valve end of each cylinder. A plurality of sealing members, each located near the open end of each cylinder, substantially eliminates blow-by from this lubricating passageway, thereby significantly increasing volumetric efficiency. The resulting improved lubrication, in combination with unique spring-biased holddown assemblies, permits use of variable-angle swash-plate arrangements that require neither dog-bones at the outer ends of the pistons nor conventional nutating-only wobblers.
