    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 two-lobe sliding-vane rotary moving-fluid device (FIG. 1) comprises a cylindrical rotor 11 having vanes 12 slidable in substantially radial directions therein, the tip of each vane maintaining substantial contact with the inner cylindrical surface 13 of a cam 14 surrounding the rotor as it traverses sealing spaces 15, 16, 17, 18, and port spaces 20, 21, 22, 23 in the cam alternately during rotation. The port spaces are formed largely of flexible laminations 30, 31, 32, 33; so the cam is deformable by adjusting forces against its rigid portions 25, 26, 27, 28 to change its shape and thus to vary the fluid displacement by adjusting the relative positions of the rotor and the sealing spaces. Throughout the range of displacement positions, any appreciable radial sliding of a vane is only inward as it traverses and maintains substantial contact with the inner surface of each sealing space. Such surface is substantially circular in cross section (FIG. 2), and relative movement of the center of rotation 60 of the rotor is substantially along a portion of the radius 73 from the center of curvature 62 of the inner surface to the trailing edge 68 of the sealing space 15, where the center of rotation can be closer to the sealing space than the center of curvature. The relative movement is substantially along an extension of the radius 74 to the leading edge 71 of the sealing space 16, where the center of rotation 60 can be farther than the center of curvature 63 of the inner surface of the sealing space. A fixed-displacement device is similar, except that the cam is not deformable.
