Patent number: 8267231Abstract: An electrically variable transmission (EVT) includes two shafts and a selectable one-way clutch (SOWC) having a first and second ring. The SOWC selectively connects the shafts, and is applied by moving the first ring and a blocking device in an axial direction into frictional contact with the second ring. A hydraulic piston applies the SOWC and a return spring releases it. The SOWC freewheels in both directions, or holds torque in one or both directions, depending on how the blocking device is rotated. A method for reducing losses in an EVT includes axially moving a second ring and blocking device of a SOWC into contact with a first ring, rotating the blocking device using frictional contact with the first ring, locking rotation of the first ring to apply the SOWC, and moving the second ring and blocking device an axial distance from the first ring to release the SOWC.Type: GrantFiled: August 8, 2008Date of Patent: September 18, 2012Assignee: GM Global Technology Operations LLCInventor: Alan G. Holmes

Patent number: 8261636Abstract: A quick-turn wrench includes a driving head with an axle hole. One side of the axle hole has a claw. A ratchet ring is accommodated in the axle hole. One end of the ratchet ring extends outside the axle hole and connects to a wrench handle. The ratchet ring is surrounded by a ratchet part that correspondingly engages the claw. A transmission rod is inserted into the ratchet ring, with one end having a transmission part. A bottom plate is disposed at the bottom of the axle hole. The end surface of the bottom plate facing the axle hole has a sliding groove. A pushing element is disposed in the sliding groove corresponding to the claw. The transmission part of the transmission rod connects to the pushing element. As the transmission rod rotates, the pushing element is driven to push the claw to release the fixing state between the claw and the ratchet ring.Type: GrantFiled: January 21, 2011Date of Patent: September 11, 2012Assignee: Advance Team Power Inc.Inventor: Chun-Lang Lin

Publication number: 20120152682Abstract: A one-way ratchet unit for a bicycle wheel has first and second meshing parts and an elastic member. The meshing parts are respectively configured on the bicycle wheel and the sprocket driving seat, their first and second one-way ratchets both comprise ratchet tips, ratchet roots and oblique guiding facets. The ratchet tips of the first or second one-way ratchet are configured with at least one wedge on partial positions, and the positions on the ratchet tips of the first or second one-way ratchet not forming the wedges form convex resisting edges. The ratchet roots of the second or first one-way ratchet are configured with wedge avoiding parts on partial positions, so that when the first and second one-way ratchets mesh each other and the resisting edges of the ratchet tips resist against the ratchet roots, said ratchet tips can be aligned and go into the wedge avoiding parts.Type: ApplicationFiled: November 9, 2011Publication date: June 21, 2012Applicant: FOSS WORLDWIDE INC.Inventors: Tseng-Ping TIEN, Hao-Jan Wang

Patent number: 8087502Abstract: An actuator shifts a selectable one-way clutch (SOWC) between a plurality of operating modes. A first spring has a preload compression that is equivalent to a first start pressure. A second spring, disposed adjacent to the first spring, has a preload compression that is equivalent to a second start pressure. A plunger movably contacts the first spring and a slide plate movably extends from the plunger. The slide plate engages the SOWC such that the SOWC shifts between the operating modes in response to movement of the slide plate. The first spring is compressible from beyond the preload compression to a first stop position as the pressure is increased from the first start pressure to a first stop pressure. The second spring is compressible from beyond the respective preload compression to a second stop position as the pressure is increased from the second start pressure to a second stop pressure.Type: GrantFiled: April 2, 2009Date of Patent: January 3, 2012Assignee: GM Global Technology Operations LLCInventors: Fazad Samie, Andrew L.

Patent number: 8083042Abstract: A selectable one-way clutch (SOWC) is provided for use with a vehicle transmission, and has a first race with a plurality of strut pockets, a moveable selector plate, symmetrical torque-holding elements or struts, and a second race that is rotatably engageable with a torque input device. The selector plate has a plurality of windows, and the struts selectively prevent rotation of the second race in either rotational direction depending on the position of the selector plate. The struts have a cylindrical portion and a pair of strut wings each having a free end. The strut wings connect to the cylindrical portion, and a different one of the free ends engages a strut pocket when an opposite strut wing is depressed in order to prevent rotation of the second race.Type: GrantFiled: December 7, 2007Date of Patent: December 27, 2011Assignee: GM Global Technology Operations LLCInventors: Farzad Samie, Andrew L.
