Patent number: 8776971Abstract: 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.Type: GrantFiled: March 23, 2007Date of Patent: July 15, 2014Assignee: Schaeffler Technologies AG & Co.

Patent number: 8727335Abstract: A gear assembly including a driving gear and a driven gear and an electronic device are provided. The driving gear includes a pawl pivoted on a first surface and an elastic member disposed in a slot of the driving gear. The driven gear includes a ratchet disposed on a second surface facing the first surface. When the driving gear rotates with a driving speed along a driving direction, a centrifugal force is generated to drive the pawl moving to a clutching position to be engaged with the ratchet and drives the driven gear rotating with the driving gear. When the driving gear rotates with a nominal speed slower than the driving speed along a direction opposite to the driving direction, the engagement between the pawl and the ratchet is released, and the pawl is back to a nominal position so the driven gear does not rotate with the driving gear.Type: GrantFiled: December 27, 2012Date of Patent: May 20, 2014Assignees: Cal-Comp Precision (Singapore) Limited, Cal-Comp Electronics & Communications Company LimitedInventor: Domingo Abao Vicente, Jr.
