Patent number: 9051980Abstract: A torque transmitting device for use in an automotive transmission is provided. The device includes an inner annular race and an outer annular race disposed concentrically around the inner annular race. A selector plate is disposed adjacent to the inner and outer annular races, the selector plate being movable with respect to the inner and outer races. Multiple control elements are pivotally connected to the selector plate. The control elements are disposed between the inner and outer races. A plurality of sprag elements is disposed between the inner and outer races. Each sprag element is disposed adjacent to a control element.Type: GrantFiled: April 26, 2013Date of Patent: June 9, 2015Assignee: GM Global Technology Operations, LLCInventors: Randal William Arndt, Douglas John Dwenger

Patent number: 8967353Abstract: A transmission includes a housing defining a sealed interior and an input hub rotatably coupled to the housing. A gear set is disposed within the housing and configured for receiving a torque from an engine. The transmission further includes an isolator assembly and a bypass clutch, each disposed within the sealed interior of the housing. The isolator assembly is configured for selectively damping drivetrain inertia and/or vibration. The bypass clutch selectively engages and disengages the isolator assembly.Type: GrantFiled: October 30, 2009Date of Patent: March 3, 2015Assignee: GM Global Technology Operations LLCInventors: Victor M. Roses, John A. Diemer, Randy Lewis Melanson, Douglas John Dwenger, Randal William Arndt, Pete R. Garcia, Michael L. Duhaime

Patent number: 8409050Abstract: A gear retention assembly for retaining a gear that has a plurality of gear outer splines includes a gear housing and a retaining ring. The gear housing has a first end, a second end, and a plurality of inner splines each including a ramp portion. The second end of the gear housing includes an annular continuous rolled lip, where the continuous rolled lip and the ramp portions of the plurality of inner splines define a groove. The plurality of inner splines engage with the gear outer splines of the gear to transmit torque between the gear and the gear housing. The retaining ring is disposed in the groove and axially retains the gear. The rolled lip axially retains the retaining ring.Type: GrantFiled: November 11, 2009Date of Patent: April 2, 2013Assignee: GM Global Technology Operations LLCInventors: Scott William Heitzenrater, Boris Burgman, Douglas John Dwenger, John A. Diemer, Randal William Arndt

Patent number: 5803222Abstract: A friction torque transmitting mechanism has a plurality of reaction plates interleaved with a plurality of friction drive plates. The reaction plates are brought into frictional contact with the drive plates by a fluid operated piston, such that a transfer of torque can be conducted through the frictional engagement of the plates. The reaction plates have a reaction portion disposed in a slot in a housing. One of the reaction plates has an axially extending reaction tab positioned between the reaction portions of the remaining plates and the sidewall of the slot. The reaction forces on the reaction portions are transmitted to the sidewall through the reaction tab.Type: GrantFiled: February 27, 1997Date of Patent: September 8, 1998Assignee: General Motors CorporationInventor: Randal William Arndt
