  • Patent number: 9115644
    Abstract: A turbocharger system for an air-throttled engine includes a variable flow expander (VFE) in the intake air conduit system that supplies intake air to the engine. At part-load operation, the VFE expands the air by an amount that is controllable, and thus regulates the air flow as needed by the engine. The power extracted by the VFE from the intake air flow is fed to the turbocharger, which helps to achieve quicker turbocharger response and improve scavenging of exhaust gases from the engine. The VFE can be a variable expansion ratio turbine.

  • Patent number: 8967956
    Abstract: A variable-nozzle assembly for a turbocharger includes a generally annular nozzle ring and an array of vanes rotatably mounted to the nozzle ring such that the vanes can be pivoted about their axes for regulating exhaust gas flow to the turbine wheel. A unison ring engages vane arms that are affixed to axles of the vanes, such that rotation of the unison ring causes the vanes to pivot between a closed position and an open position. The vanes have proximal ends that are adjacent a face of the nozzle ring. A vane sealing member is supported on the nozzle ring and has a portion disposed between the proximal ends of the vanes and the face of the nozzle ring. The unison ring includes cams that engage cam followers. Rotational movement of the unison ring causes the cam followers to be moved axially and thereby urge the vane sealing member against the proximal ends of the vanes.

  • Patent number: 8967955
    Abstract: A variable nozzle for a turbocharger includes a plurality of vanes rotatably mounted on a nozzle ring and disposed in a nozzle flow path defined between the nozzle ring and an opposite nozzle wall. Either or both of the faces of the nozzle ring and nozzle wall include(s) grooves extending substantially transverse to a general flow direction of the flow through the nozzle, and there are clearances between the ends of the vanes and the adjacent faces. Leakage flow through the clearance between the end of each vane and the adjacent face having the grooves must proceed across the grooves, and thus a labyrinthine flow passage is presented to the leakage flow. The labyrinthine passage has a greater resistance to flow than would be the case without the grooves. Accordingly, leakage flow is reduced, which is beneficial to turbine efficiency.

  • Patent number: 8884477
    Abstract: An electro-motor drive, in particular for a fan drive of a motor vehicle, includes a commutator motor, a motor shaft of which is rotatably mounted on axially opposite sides in shaft bearings facing away from the bearing shield in order to substantially dampen the sound of at least bearing play-related contact noise and vibration or humming noise.

  • Patent number: 8443956
    Abstract: A dual clutch transmission having a hydraulic circuit for controlling and cooling the clutches of a dual clutch transmission having lube valves in fluid communication with a source of pressurized fluid and wherein the cooling flow is controlled by a solenoid which is adapted to move a valve member to produce a flow area through the valve that is an inverse function of the current delivered to the solenoid and so as to deliver a predetermined control solenoid pressure ultimately to each of the clutches of a dual clutch transmission.

  • Patent number: 8234817
    Abstract: To reduce stresses during closing of a manually closable body component, e.g. a door, a control device and a method of controlling closing movement in which, during the closing movement, from an opened position, the body component passes through first movement range in which the body component is moved towards the closed position without any action by a control member, and, thereafter, the body component passes through a second movement range in which the closing movement is varied by the action of the control member that residual kinetic energy of the body component does not exceed a predetermined limit value after passing through the second movement range, irrespective of the initial speed. The residual kinetic energy is not sufficient to close the body component automatically, so it is automatically drawn in a third movement range until a pre catch or main catch of a lock is reached.

  • Publication number: 20090217596
    Abstract: In order to reduce the stresses occurring during the closing of a manually closable body component, e.g. a door, a method of controlling the closing movement is proposed in which, during the closing movement, departing from an opened position, the body component passes through a first movement range in which the body component is moved towards the closed position without any action by a control member, and, following the first movement range, the body component passes through a second movement range in which the closing movement of the body component is varied in such a manner by the action of the control member that the residual kinetic energy of the body component does not exceed a predetermined limit value after passing through the second movement range, irrespective of the initial speed. The residual kinetic energy is not sufficient to close the body component automatically.

  • Patent number: 7267631
    Abstract: An automatic transmission having a start-up clutch assembly includes a transmission housing, an input drive shaft, and an output drive shaft. An input planetary gear assembly is also included that has a sun gear and a ring gear, with a plurality of planet gears disposed therebetween, the ring gear operatively connected to the input drive shaft. A start-up clutch is operatively disposed between the transmission housing and the sun gear and is adapted to allow the sun gear to freely rotate when the start-up clutch is disengaged so that no torque is transferred. The start-up clutch is further adapted to engage and hold the sun gear stationary so that torque is fully transferred. The start-up clutch is further still adapted to provide a varying and controllable slipping interaction between the disengaged and engaged positions at vehicle start-up thereby providing the vehicle with a smooth transition from stationary to moving.
