  • Patent number: 10914239
    Abstract: Disclosed is a high-speed section disconnect for a driven turbocharger with a traction drive. The turbo shaft is attached to a turbine and compressor, and interfaces with a high-speed traction drive. A mechanical coupling connects the traction drive to a transmission, which is connected to the engine so that power can flow to or from the turbo shaft, but the mechanical coupling can be selectively disconnected so that the high-speed section of the driven turbocharger can also be decoupled from the engine during certain operating conditions to reduce mechanical losses in the system.

  • Patent number: 7896144
    Abstract: The present invention broadly comprises a stator and one-way clutch assembly including a segment of a stator, a one-way clutch engaged with the segment, and at least one elastically deformable element engaged with the segment and the clutch and arranged to dampen transfer of torque from the stator to the clutch. In some aspects, the clutch includes a first plate and the deformable element is engaged with the segment and the plate. The segment urges the deformable element against the first plate. The first plate is arranged to rotate in response to the urging. The segment and the first plate are arranged to rotationally lock. The first plate and a second plate, connected to a clutch hub, rotationally lock in response to the urging, and the segment and the first plate are arranged to rotationally lock following the locking of the first and second plates.

  • Patent number: 7878316
    Abstract: A high torque capacity one-way clutch includes a first, inner annulus nested within a second, outer annulus. The inner annulus includes a plurality of transverse grooves on its outer surface as well as a centrally disposed circumferential groove. A like plurality of moveable struts having a central opening are received within respective grooves in the inner annulus and are retained there by a circumferential band passing through the openings in the struts and received in the circumferential groove. The outer annulus includes a plurality of transverse grooves on its inner surface and receives the inner annulus, struts and circumferential band. Upon relative rotation of the annuli in one direction, the struts engage the grooves and inhibit rotation between the annuli, thereby transmitting torque. Upon relative rotation in the opposite direction, the struts slide along the inner surface of the outer annulus without engaging and thus do not transmit torque.

  • Patent number: 7866454
    Abstract: A torque converter includes at least two thrust bearings disposed on respective axially-opposite sides of a radially-inward portion of a stator. The stator includes a non-rotatable member, a rotatable member, and a one-way clutch. The rotatable member has a cylindrical portion having an inner peripheral surface interlocked with the one-way clutch, and an extension portion which extends from an approximately axially-central region of the cylindrical portion in a radially-outward direction relative to the cylindrical portion, and has an axial thickness less than that of the cylindrical portion. The thrust bearings are disposed to clamp the extension portion from respective axially-opposite sides of the extension portion at respective positions located radially outwardly relative to the cylindrical portion, so as to facilitate reduction in axial dimension of the torque converter.

  • Patent number: 7849990
    Abstract: The present invention broadly comprises a one-way clutch in an automotive drive component. In some aspect, the component is a stator and the clutch includes first, second, and third radially disposed elements. The first and second elements lockingly engage. The third element is between the first and second plates and hydraulically or mechanically dampens energy associated with the locking engagement. In some aspects, the third element forms structures to partially enclose torque converter fluid and one of the first or second elements rotates to causes displacement of the fluid. In some aspects, the clutch includes a fourth radially disposed element at least partially blocking openings in the first or second elements. In some aspects, the third element includes at least one elastically deformable extension and rotation of one of the first or second elements causes the first and second elements to compress the at least one elastically deformable extension.

  • Patent number: 7850420
    Abstract: The present invention broadly comprises a blade for a torque converter stator including a first blade segment connected to inner and outer circumferential sections of the stator and a second blade segment, separately formed from the first blade segment, and connected to the circumferential sections. In some aspects, the blade segments are: in contact along edges, overlapped, circumferentially misaligned, at least partially folded, stamped, or cast. Configurations of the blade segments can be selected to modify performance characteristics of the stator such as torque ratio, efficiency, and capacity. In some aspects, the blade segments are in a circumferential alignment, and the stator includes an alignment element operatively arranged to control the circumferential alignment, for example, in response to pressure from fluid in the stator upon the blade. In some aspects, the stator includes axial halves, separately formed and fixedly connected and the blade segments are connected to respective halves.

  • Patent number: 7832536
    Abstract: A supporting structure for a one-way clutch supports the one-way clutch arranged between a stator of a torque converter for transmitting a torque from an engine to a transmission side via a fluid and a shaft at the transmission side. The supporting structure includes a first protrusion and a first contact plate. The first protrusion is provided at an inner periphery of the stator and protruding towards an inner-peripheral side of the stator. The first contact plate is fitted between the one-way clutch and the first protrusion of the stator and supports the one-way clutch while restraining an axial movement of the one-way clutch.

  • Publication number: 20100064675
    Abstract: Improvements in a transmission are provided for transferring power from a power source to a work unit. The pump transfers energy received from the power source into a fluid or gas. The first turbine is fixed to output shaft, and a plurality of additional turbines are fixed on either one-way overrunning clutches or multi-disc clutches and these clutches are fixed to the output shaft and after each turbine is a multi-valves that discharges the fluid or gas. After all of the multi-stage turbines a first planetary gear set connects the transmission to the vehicle or work unit. The second planetary gear set is located between the last turbine and the first planetary gear set. During braking the planetary gear set reverses turning direction of the turbines and convert the turbines into pumps where they will pump low pressure fluid to a high pressure accumulator.

  • Patent number: 7640734
    Abstract: A turbine hub has a through-hole extending through it in the axial direction. This through-hole is provided such that a portion of a thrust bearing covers part of the through-hole when the thrust bearing has been properly assembled onto the turbine hub, which enables assembly of the thrust bearing to be checked by the relative position relationship between the through-hole and the thrust bearing. If a portion of the thrust bearing does not cover part of the through-hole, it can be determined that either the thrust bearing is not assembled or that it has not been assembled properly.
