  • Publication number: 20150204416
    Abstract: A torsional vibration damper includes a pendulum flange which is rotatable around an axis of rotation, having a cutout, as well as two pendulum mass pairs which are movably attached to the pendulum flange, adjacent to each other in the circumferential direction, and an elastic element to damp mutual colliding of adjacent pendulum mass pairs. The pendulum mass pairs each comprise two pendulum masses which are positioned opposite each other relative to the pendulum flange, and a bolt which runs through the cutout and connects the pendulum masses to each other axially. In the area of the cutout an elastic element is attached to each of the two bolts, which is set up to collide with the other elastic element in the circumferential direction.

  • Patent number: 8776971
    Abstract: The present invention broadly comprises a stator and clutch assembly in a torque converter. The stator has a segment radially disposed between stator blades and a stator axis. The one-way clutch has a plate connected to a hub. The segment forms a portion of the clutch and the stator is axially displaceable to control operation of the clutch. A displacement element urges the stator in a first axial direction. The stator is arranged to move in a second axial direction, opposite the first axial direction, in response to pressure from fluid in the torque converter. In some aspects, the displacement element is selected from the group consisting of a coil spring and a wave spring. In some aspects, the one-way clutch is arranged to disengage when the stator is sufficiently displaced in the first direction and to engage when the stator is sufficiently displaced in the second direction.
