摘要： An axial piston pump and an axial piston motor, mounted in a housing each have a rotating element and a non-rotating element. Each non-rotating element is mounted for tilting movement about axes transverse to the axes of rotation of the rotating element, on trunnions in its own respective pair of mounting journals in the housing for controlling the transmission ratio. The pump and the motor are disposed side-by-side in the housing with the axes of rotation approximately parallel to each other. A stationary manifold, fixed to the housing, has surfaces in contact with the rotating pump element and the rotating motor element. Fluid passages open in the surfaces in fluid communication with the pump and motor cylinders through a pump/manifold interface. Internal fluid passages in the stationary manifold convey fluid pressurized in the pump directly to the motor, and convey spent fluid displaced from the motor back to the pump.

摘要： A hydraulic unit has a drive shaft (52) mounted in a manifold block (54) and coupled to a torque plate (80) on a central axis. A bent axis motive unit (60) has a yoke connected to the manifold block supported for rotation on the yoke. Hollow pistons (100) in cylinders in the cylinder block allow fluid to flow through a torque plate into and form the manifold without the necessity for passing fluid through an articulating member that pivots the cylinder block.

摘要： A hydrostatic axial piston transmission having a continuously variable transmission ratio includes an axial piston pump driven by an input shaft, the pump having an annular pump cylinder block with a ring of cylinders in which pump pistons reciprocate to pressurize and displace fluid from the pump cylinders. The pump is also coupled to an output shaft for conveying reaction torque from the input shaft directly to the output shaft as a first output torque component. An axial piston hydraulic motor has an annular motor cylinder block with a ring of motor cylinders in which motor pistons reciprocate in a power stroke to apply output torque to the output shaft, and a displacement stroke in which spent fluid is displaced from the motor cylinders for return to the pump cylinders. The pump cylinder block is concentrically disposed within the annulus of the motor cylinder block, and the input shaft and the output shaft lie on a longitudinal axis through the annulus. The pump cylinder block lies against a flat surface which is tilted at an angle with respect to the longitudinal axis of the machine, so that rotation of the pump cylinder block relative to the flat surface causes the pump pistons to reciprocate and displace fluid under pressure through commutating passages to the motor. Rotation of the input shaft drives the pump to displace pressurized fluid through pressure passages while also transmitting reaction torque to the output shaft. The fluid pressurized by the pump energizes the motor to produce a second component of output torque in the output shaft.

摘要： A continuously variable transmission, which allows recovering braking energy from a vehicle for later use in accelerating the vehicle and/or engine starting, includes a vane type pump and stator in a case, each with flexible cam rings. The pump cam ring and the stator cam ring can both be flexed to change the displacement of the pump and the stator. A first connection establishes fluid communication between a tapering volume sector of the pump swept volume and a tapering volume sector of the stator unit working volume, and a second connection establishes fluid communication between a flaring volume sector of the pump swept volume and a flaring volume sector of the stator unit working volume. A valve is connected to the first and second connections and a hydraulic accumulator. The valve can establish communication between the hydraulic accumulator and the second connection to pressurize the hydraulic accumulator with fluid pressurized in the flaring volume sector of the stator working volume and the pump swept volume by the pump cam ring overdriving the pump rotor, thereby storing energy from the vehicle in the accumulator. Or the valve can establish communication between the hydraulic accumulator and the first connection to pressurize the tapering volume sector of the stator working volume and the pump swept volume so that the pressurized fluid in the accumulator drives the cam ring and the output shaft to recover and use the stored energy in the accumulator.

摘要： A continuously variable power transmission has a fixed mounting plinth, by which the transmission is mounted to a fixed structure, and an output shaft, to which an output device can be connected. A pintle having a flat radial slab and an axial arbor supports a radial piston pump rotor an one end of the arbor and a radial piston motor rotor on the other end of the arbor. A driven pulley surrounds the transmission and constitutes its exterior shell within which working fluid is contained. The pulley is coupled to a ring gear of a planetary gear set having a planet carrier with planet gears engaged between the ring gear and a sun gear. The sun gear is coupled to and drives the pump rotor, and the carrier is coupled to the output shaft. Working fluid pressurized by the pump is conveyed to the motor rotor to generate torque in the motor which is carried back to the planet carrier.

摘要： An infinitely variable hydrostatic transmission includes a radial piston pump having outwardly opening pump cylinders containing radial pump pistons, and a radial piston motor, arranged concentrically around the pump, having inwardly opening motor cylinders containing radial motor pistons. Fluid passages in the transmission intermittently connect the pump cylinders and the motor cylinders in a closed fluid flow circuit. A flexible cam ring is radially interposed between the pump and the motor in load bearing relation to the pump pistons on an inside surface of the cam ring, and in load bearing relation to the motor pistons on an outside surface of the cam ring. An input shaft is coupled in torque driving relation to the pump, and an output shaft is coupled in torque driven relation through a commutator plate to the cam ring. An adjustment mechanism is provided for adjusting the cam ring to a desired radial profile to set the transmission to a desired transmission ratio. A fluid distribution system has passages, including kidney shaped slots through the comutator plate, for fluid flow of fluid pressurized in the pump cylinders to the motor cylinders during a power stroke of the pump and motor pistons, and for fluid flow of spent fluid from the motor cylinders to the pump cylinders during a suction phase of the stroke of the pump and motor pistons. A control system adjusts the profile of the cam ring to control the transmission ratio, and a pressure compensator automatically reduces the transmission ratio when the resistance torque on the output shaft exceeds a predetermined value, as when the vehicle is ascending a steep hill.

摘要： A hydraulic machine having a continuously variable displacement includes a vane rotor having a plurality of radial vanes thereon and a connection for a torque transmitting shaft driven by a prime mover such as an engine or an electric motor. A cam ring is supported in a position surrounding the vane rotor and has an interior surface facing the vane rotor. The interior surface and the vane rotor define between them a working volume swept by the vanes. The cam ring has flexible portions therearound capable of flexing radially when inwardly directed radial forces are exerted thereon to change the shape of the swept volume within the cam ring. A control mechanism in the housing has an adjustable force generating device bearing against a force exerting member engaged with the cam ring for exerting a squeezing force on the ring to distort the cross-sectional shape of the cam ring and the swept volume within the cam ring. The adjustable force generating device includes a rod having a wedge-shaped notch therein, and the force exerting member includes a toggle having one end fitted into the notch and an opposite end engaged in a wedge shaped notch in an abutment on the cam ring. The cross-sectional shape of the cam ring swept by the vanes may be continuously adjusted by the control mechanism thereby continuously adjusting the displacement of the vane rotor per revolution thereof.

摘要： A continuously variable transmission includes a housing in which input and output shafts are journaled for rotation. Both input and output shafts have torque couplings for connection to drive shafts of a prime mover and a driven load such as the drive axle of a vehicle. The input shaft is coupled to a vane rotor of a vane-type pump having radially extending pump vanes driven by the pump rotor around a pump working volume between two axially spaced pump side plates surfaces and within an inside surface of a flexible pump cam ring spaced radially from the pump rotor. The pump vanes each have a radial end edge remote from the pump rotor and in contact with the pump cam surface. A stator hub is fixed to the housing and has radially extending stator vanes projecting radially into a stator working volume between two axially spaced stator side plate surfaces and between a cam surface of a flexible stator cam ring and the radially spaced surface of the stator hub. The stator vanes each have a radial end edge remote from the hub and in contact with the stator cam surface. Torque is transmitted from the stator cam ring and the pump cam ring to the output shaft by a torque coupling. Fluid openings are provided for passing fluid pressurized in the pump directly from the pump working volume into the stator, and for passing fluid displaced from the stator directly from the stator working volume into suction sectors of the pump. A cam ring adjustment mechanism is mounted in the housing for changing the radial spacing of portions of the pump cam ring from the pump rotor, and for changing the radial spacing of portions of the stator cam ring from the stator hub. Rotation of the pump rotor by the input shaft pressurizes fluid in the pump working volume which acts against the pump cam ring to generate torque that is transmitted to the output shaft, and the pressurized fluid in the pump working volume communicates through the fluid openings to pressurize fluid in the stator working volume which acts against the stator cam ring to generate additional torque that is transmitted to the output shaft, and the cam adjustment mechanism is operated to reciprocally change the displacement of the pump and the stator to change the transmission ratio of the transmission.

摘要： A parallel hydromechanical continuously variable transmission has a housing (107) that holds a make-up pump (52), and has internal cavities for holding operating assemblies of the transmission, including an axial piston pump (50) and an axial piston motor (60). The pump (50) and motor (60) each has a rotating element (206) and a non-rotating element (258). Each non-rotating pump element is mounted for tilting movement on trunnions (258P) in its own respective pair of mounting journals in the housing (107). The tilting axes of the non-rotating elements (258) lie transverse to the axes of rotation of the rotating elements (206). The pump (50) and the motor (60) are disposed side-by-side in the housing (107) with the axes of rotation approximately parallel to each other. A stationary manifold (70), fixed to the housing (107), has one surface in contact with the rotating pump element (206P) and a second surface in contact with the rotating motor element (206M). Fluid passages (149, 208) open in the two surfaces in fluid communication with the pump and motor cylinders (206) through a pump/manifold interface. Internal fluid passages (149, 208) in the stationary manifold (70) convey fluid pressurized in the pump (50) directly to the motor (60), and convey spent fluid displaced from the motor back to the pump. The transmission ratio is controlled by the tilt angle of the non-rotating pump and motor elements (258). A tilt angle control apparatus (100) attached to the housing (107) and to the non-rotating pump and motor elements (258) governs that tilt angle.
