Abstract: A bi-directional overrunning clutch assembly employed in connection with a reduced capacity low friction clutch to provide low and reverse gears in a transmission. The clutch assembly including an inner race, an outer race, and engagement members supported therebetween. The inner race is operatively coupled to the transmission casing and the outer race is operatively coupled to the ring gear of the gear set as well as the inner race of the friction clutch assembly. The clutch assembly further includes at least one actuating cam. The actuating cam operates to actuate the engagement members to provide four separate modes of operation between the inner and outer races of the clutch assembly.

Abstract: An integrated control module for a dual clutch transmission having an integrated shift actuator position sensor assembly that includes a valve body having a plurality of raised portions juxtaposed to each other with a plurality of shift actuator bores piston bores formed therein. A plurality of shift actuators are adapted to operatively move the synchronizers of said transmission to affect gear changes, and include a plurality of shift actuator pistons slidingly disposed within the shift actuator bores. A hydraulic control assembly is adapted to control the operative hydraulic functions of the transmission. A transmission control assembly in electrical communication with the hydraulic control assembly and with a higher level vehicle control system provides the requisite signals to control the hydraulic control assembly.

Abstract: An integrated control module for a dual clutch transmission that includes a valve body having an inlet, a plurality of outlets with a plurality of internal hydraulic passages disposed therebetween, and a hydraulic control assembly mounted to the valve body. The hydraulic control assembly is adapted to operatively control the pressurized hydraulic fluid from the inlet through the plurality of internal hydraulic passages to the plurality of outlets. The hydraulic control assembly includes at least one assembly from a group including, a shift actuation control assembly adapted to actuate the synchronizers of the transmission, a clutch actuation control assembly adapted to allow the selective and independent engagement and disengagement of each clutch, and a clutch cooling fluid control assembly adapted to control the cooling fluid provided to the clutches of the transmission.

Abstract: A variable torsional damper rotatably supported for translating torque between a prime mover and the input of a transmission. The variable torsional damper includes a torque input member operatively connected for rotation with the power take off of a prime mover, an output member operatively connected for rotation with the input to a transmission and a plurality of damping members interposed between the input member and the output member. The damping members act to translate torque between the input member and the output member to dampen torsional forces generated between the prime mover and the transmission. A magneto-rheological damper assembly is disposed in parallel with the damping members and is adapted to operatively vary the hysteresis between the input member and the output member of the variable torsional damper.
