摘要： A hydraulic mechanical transmission includes a first hydraulic unit having a first shaft and a second hydraulic unit having a second shaft. The second hydraulic unit is connected in hydraulic fluid communication with the first hydraulic unit by high and low pressure lines. A mechanical torque transfer arrangement transfers torque between the first shaft of the first hydraulic unit and a rotatable housing of the second hydraulic unit. One of the first and second hydraulic units operates as a hydraulic pump and the other operates as a hydraulic motor, and both of the first and second hydraulic units have variable displacement.

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： To control the transmission ratio of a continuously variable hydrostatic transmission including an input shaft, an output shaft, an pump unit driven by the input shaft, a grounded motor unit, and an a wedge-shaped swashplate drivingly and pivotally connected to the output shaft in hydraulic fluid-communicating position between the pump and motor units, a ratio controller is provided having a hydraulically actuated piston incorporated internally of the output shaft. A pilot valve, also incorporated internally of the output shaft, operates to create differential fluid pressures at opposite end faces of the piston, forcing axial motion of the piston and ratio-changing pivotal movement of the swashplate linked to the piston.

摘要： A hydrostatic assembly employing a 1st hydraulic piston drive unit is described in which the output is increased without using additional servo assemblies by incorporating a 2nd hydraulic piston drive unit, coupling the drive shafts of both drive units together, and employing a common means to simultaneously adjust displacement of both the 1st and 2nd hydraulic piston drive units. In such embodiments, coupling the drive shafts together such that the 1st hydraulic piston drive unit is rotationally offset with respect to the 2nd hydraulic piston drive allows for a reduction in the amplitude of pressure pulsations associated with the hydrostatic assembly output, thereby smoothing out operation and improving durability.

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 hydrostatic transmission includes an input shaft connected to drive a hydraulic pump unit, a grounded hydraulic motor unit, and an output shaft. A wedge-shaped swashplate is pivotally mounted to the output shaft in driving connection to receive output torque resulting from the exchange of pressurized hydraulic fluid between the pump and motor units through slots in the swashplate. A hydraulically actuated ratio controller shifts the axial positions of spherical bearings mounting a pump portplate in the hydraulic pump unit and a motor portplate in the hydraulic motor unit to adjust the swashplate angle relative to the output shaft axis and thereby change transmission ratio.
