Abstract: A coupling device operatively arranged between a drive unit and a rotary driven unit including a housing having first and second housing shells, a flange and a clutch assembly arranged to controllably engage a damper. The clutch assembly and damper are positioned within the housing, and the clutch assembly is arranged to directly frictionally engage the flange and first and second housing shells. The damper includes ends bearing against a portion of the flange.

Abstract: A hydrokinetic torque converter includes an impeller cover and a bypass clutch located within the impeller cover. The impeller cover has welded to it a clutch plate, which is connected by a spline to a ring, which is riveted to a clutch piston rotatably supported on a turbine rotor hub. A drive ring is driveably connected to the ring and a pump shaft by a connection that permits axial movement of the piston-clutch plate assembly relative to the pump shaft.

Abstract: A hydrokinetic torque converter includes an impeller housing and a bypass clutch located within the impeller housing. The impeller cover has welded to it a clutch plate, which is connected by a splined connection to a clutch piston rotatably supported on a turbine rotor. A drive ring carries friction surfaces adjacent the clutch piston and clutch plate. The drive ring extends axially into engagement with a helical spring carried in a damper assembly arranged in series with the damper between the impeller cover and the input shaft of the transmission.

Abstract: A hydrokinetic torque converter and lockup clutch assembly comprising an impeller housing and a clutch construction situated within the housing comprising a clutch plate in the form of a piston having formed thereon an annular friction surface, a friction disc located between the friction surface on the clutch plate and an adjacent wall of the impeller housing and having an inner margin secured to the impeller housing at a location radially inward of the friction surface, friction material formed on the friction disc and flow passages for establishing a circuitous cooling oil flow path across the dynamic friction surfaces of the clutch to establish cooling and for eliminating wear as the pressure in the clutch control pressure chamber is modulated to effect a continuous slipping of the clutch surfaces during operation of the converter, the friction disc providing a shield that minimizes heat transfer to the impeller housing and for providing maximum compliance of the face of the friction surface with respect
