摘要： La transmision incluye un complejo de engranaje orbital en combinacion con una bomba y motor hidraulicos variables. La entrada a la transmision se incrementa en velocidad por el engranaje orbital de tal manera que, cuando la bomba y motor no se encuentran operando, el orbitador se encuentra estacionario y el engranaje orbital produce una condicion de sobremarcha. Una reduccion de la velocidad se realiza al girar la red con el dispositivo giratorio de red, proporcionado una reduccion de la velocidad directa. La bomba y motor son preferentemente maquinas hidraulicas de piston grande con platos oscilantes infinitamente variables. Las maquinas hidraulicas preferentemente tienen cabezales motores estabilizados por cardanes completos y placas de retencion con orificios alargados para que los pistones grandes eliminen los impactos posibles entre las placas de retencion y los extremos superiores de los pistones grandes cuando los platos oscilantes se encuentran en o cerca de su angulo maximo de inclinacion.

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 hold-down 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.

摘要： The transmission (400) includes an orbital gear complex (404, 416) in combination with a variable hydraulic pump (408) and motor (406). The input (420) to the transmission is increased in speed by the orbital gearing such that, when the pump and motor are not operating, the orbiter (404) is stationary, and the orbital gearing produces an overdrive condition. A gear reduction is accomplished by rotating the web (426) with the web-rotating device (403), providing a high gear reduction. The pump and motor are preferably long- piston hydraulic machines (110) 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： Smaller and lighter hydraulic pump/motors provide remarkably improved volumetric efficiency 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 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 a minimal flow of fluid to and from the valve end of each cylinder and passing between each respective cylindrical wall of each cylinder and the axial cylindrical body of each respective piston. Several embodiments are disclosed in combination with various spring-biased hold-down assemblies. The preferred embodiment includes a fixed cylinder block, a roller bearing mounting between the wobbler and rotor of a split-swash plate, with piston shoes contacting the wobbler directly without any intermediary apparatus.

摘要： A modular track suspension system is readily adapted for attachment to any presently manufactured full-size automotive vehicle built with a load-carrying frame, 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, one track under each respective side of the vehicle; and each track is frictionally driven by tandem pairs of dual-wheels with rubber tires, each tandem pair of wheels being driven, respectively, by an intermediately positioned drive-unit axle. 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 tandemly paired. Each dual-wheel is also resiliently biased in the direction of the terrain on which the vehicle is standing or moving. Driving torque is delivered to the two endless tracks through a plurality of differentials appropriately and simply connected directly with the vehicle's drive shaft. In all preferred embodiments, an additional differential that is connected with, and is responsive to, the operation of the vehicle's steering wheel superimposes additive and subtractive steering torques to the already differentiated driving torques being delivered to the left-side and right-side tracks for controlling the vehicle's direction.

摘要： A spool valve is provided with a stem portion that defines a fluid passageway formed by either (a) a single central support having a non-cylindrical curved surface shaped hydrodynamically, or (b) only a pair of sidewalls with, preferably, interior surfaces that are also shaped hydrodynamically. These stem passageways, which are designed to facilitate the flow of high-speed/high-pressure fluids controlled by the valve, are maintained in a predetermined orientation relative to the ports of the valve cylinders by a mechanism preferably including (a) a cam-following roller supported in a tang fixed to each spool and (b) a two-element cam that captures the roller within two of the parallel sides of a cam-track groove formed on the respective interior surfaces of each cam element.

摘要： A pair of distinctive spherical gears transmits rotary motion between two shafts, while allowing the angle between the shafts to vary (e.g., by even more than 40 DEG ) continuously during operation. The term "spherical" is used to distinguish these distinctive gears from conventional "cylindrical" (spur and helical) and "conical" (bevel and hypoid) gears. Several forms of spherical gear teeth are specifically detailed and applied in designs appropriate for automotive constant-velocity joints.
