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.

Torque converter arrangements and operating methods are provided herein. In one example, the torque converter includes a first attachment interface designed to rotationally couple to a prime mover and a second attachment interface designed to rotationally couple to a transmission. The torque converter further includes a lock-up clutch with an engagement spring embedded in an actuation piston, a plurality of separator plates supported by one or more guiding pins that extend through the plurality of separator plates and into a casing, and a plurality of friction plates interleaved with the plurality of separator plates, where the plurality of separator plates and friction plates are axially captured between the actuation piston and an end plate.

A torque converter includes an impeller, a turbine, a stator, a one-way clutch, and an insert molded thrust washer formed onto a retention mount that is integrally formed on one of the impeller, the turbine, the stator, and the one-way clutch. The retention mount defines an undercut. At least a portion of the insert molded thrust washer is disposed within the undercut. Interference between the retention mount and the insert molded thrust washer mounts the insert molded thrust washer to the retention mount.

A P1 hybrid module for a vehicle includes a housing, a motor stator, an input shaft, a resolver rotor, an output flange, a motor rotor, a housing plate, and a resolver stator. The housing is arranged for fixing to an engine and a multi-speed transmission. The motor stator is fixed to the housing. The input shaft is arranged for driving connection to a flange of a damper. The resolver rotor is fixed to the input shaft. The output flange is arranged for fixing to a torque converter. The motor rotor is rotatably fixed to the output flange. The housing plate is fixed to the housing by a first fastener. The resolver stator is fixed to the housing plate radially outside of the resolver rotor.

An engine damper includes a drive disc having a plurality of studs circumferentially arranged to be received in a flex plate and a driven disc connected to the drive disc by a resilient member. The driven disc defines a plurality of circumferentially arranged first holes arranged in a first pattern. A hub is configured to non-rotatably connect to a shaft. The hub defines a plurality of second holes circumferentially arranged in a second pattern that corresponds to the first pattern. Connectors are disposed in the first and second holes to connect the hub to the driven disc.

A torque damper apparatus includes an input-side plate having a pair of side plates and rotatably driven in response to drive force from a motor, a center plate coupled to an output shaft and arranged between the pair of side plates, and an elastic transmission body provided between the input-side plate and the center plate to transmit rotary drive force of the input-side plate to the center plate. The input-side plate has, at a plate surface of at least one side plate, multiple weight attachment holes for attaching a balance weight. Each weight attachment hole is formed in a long hole shape extending along a circumferential direction at an outer edge portion of the side plate.
