Patent number: 11919401Abstract: A device for power transmission within a hybrid motor vehicle and a method of operating the device. The device is a P2 module and includes a torque converter, an electric motor, a connect/disconnect clutch and a one-way clutch. The torque converter is configured to be coupled to an input member of the transmission. The electric motor includes a rotor that is fixedly connected to the input of the torque converter. The connect/disconnect clutch has an input member configured to be coupled to the output of the engine and has first and second clutch members moveable between a disengaged and engaged positons. The second clutch member is also fixedly connected to the torque converter. The one-way clutch is coupled between the connect/disconnect clutch and the torque converter and has a locked up configuration and an overrunning configuration.Type: GrantFiled: October 26, 2020Date of Patent: March 5, 2024Assignee: Exedy Globalparts CorporationInventors: Kenneth Gerard Walega, Bryant David Grytzelius

Patent number: 11754160Abstract: A torque converter having a shell formed by a front cover assembly and a rear cover. The front cover assembly further includes a front cover and a front boss, with the front boss being fixedly mounted to the front cover. The torque converter further including an impeller, a turbine located within the shell, a lock-up clutch and a piston. The piston being axially moveable relative to the front cover assembly along a central axis of the torque converter. A leaf spring, positioned between the piston and the front cover assembly, connects the piston to the front cover assembly.Type: GrantFiled: March 24, 2022Date of Patent: September 12, 2023Assignee: Exedy GlobalParts CorporationInventor: Hanjun He

Patent number: 11359706Abstract: A launch device having a front cover connectable to the output of a prime mover, an output hub connectable to the input of the transmission, an impeller driven in rotation with the front cover and a turbine fluidly coupled in rotation with the impeller. A damper includes an output member connected to and rotatable with the output hub. A lock-out clutch, when engaged, rotationally locks the damper with the front cover and includes a clutch piston which is axially and rotationally moveable relative to the output hub. A mechanical clutch piston positioner includes first and second interfaces individually associated with either the clutch piston or one of the output member or output hub. The first interface is axially and rotationally moveable relative to the second interface. Upon the first interface overrunning tire second interface, mechanical engagement of the interfaces axially positions tire clutch piston toward the front cover.Type: GrantFiled: October 1, 2019Date of Patent: June 14, 2022Assignee: Exedy GlobalParts CorporationInventors: Shinichiro Maeda, Ken Mototsune, Scott Binder

Patent number: 11300186Abstract: A launch device for coupling a rotary output of a prime mover to a rotary input of a transmission. The launch device includes a front cover connected to the rotary output member of the prime mover and an output hub connected to the rotary input of the transmission. A rear cover cooperates with the front cover to define a chamber in which an impeller and a turbine are located. A damper is coupled between the turbine and the output hub and a lock-out clutch is coupled to the damper to releasably lock the damper for rotation with one of the front and rear covers. Connecting the clutch assembly to the damper is a clutch plate in which a clutch drum of the clutch assembly is unitarily formed with the input members of the damper.Type: GrantFiled: January 29, 2019Date of Patent: April 12, 2022Assignee: Exedy GlobalParts CorporationInventor: Hanjun He

Patent number: 11293535Abstract: A launch device coupling a prime mover to a transmission. The launch device includes a front cover for connecting to the output of the prime mover and an output hub for connecting to the input of the transmission. A rear cover is connected to the front cover and cooperates to define a chamber. Within the chamber are an impeller and a turbine having a plurality of opposing blades such that hydraulic fluid is directed from the impeller blades and toward the turbine blades. A main damper is provided between the turbine and output hub of the launch device. Coupled to the main damper is a lock-out clutch configured to releasably lock the main damper for rotation with one of the front and rear covers. The launch device also includes an active dynamic damper system coupled to the main damper and configured to reduce resonance influence on the main damper.Type: GrantFiled: January 25, 2019Date of Patent: April 5, 2022Assignee: EXEDY GLOBALPARTS CORPORATIONInventors: Kenji Kitada, Scott Binder, Ken Mototsune, Daniel Leschuk

Patent number: 9709101Abstract: A clutch assembly for transmitting power from an output shaft of an engine to an input shaft of a gearbox includes annular friction surfaces on at least one of the flywheel and the pressure plate. The annular friction surface has a plurality of grooves that extend across the annular friction surface away from an inner rim of the friction surface toward an outer rim of the friction surface to prevent a reduction in friction caused by outgassing or abraded particles trapped between engaging friction surfaces.Type: GrantFiled: June 5, 2015Date of Patent: July 18, 2017Assignee: EXEDY GLOBALPARTS CORPORATIONInventor: Evan Cline

Publication number: 20150075323Abstract: A vehicle transmission includes a transmission pump body having a surface defining apertures, including an intake port, an exhaust port, and a drain back hole; a bell housing; and a steel wear plate disposed between the pump body surface and the bell housing, wherein the wear plate defines a plurality of apertures that mimic and correspond with the intake port, exhaust port and drain back hole of the pump body. The wear plate protects the bell housing from damage in the event of a catastrophic failure of a torque converter or transmission pump, without interfering with normal operation of the transmission.Type: ApplicationFiled: August 29, 2014Publication date: March 19, 2015Applicant: Exedy Globalparts CorporationInventor: Kyle House
