Abstract: A hydrokinetic coupling device (10), which comprises a axis of rotation (B) and a torque converter (12), comprising a turbine wheel (22) mounted rotationally around a rotary driven shaft, as well as a circumferential damping device (40), comprising a damper plate (42) with a radial flange (44), rotationally linked without play to the turbine wheel (22) by a connecting element (62) and which is linked with circumferential damping with the rotary driven shaft. A locking clutch (14) that comprises at least one annular friction disc (56A, 56B) sliding axially, which rotates together with the flange (44) of the damper plate (42). The friction disc (56A, 56B) is carried by the connecting element (62), which directly connects the turbine wheel (22) to the flange (44) of the damper plate (42).

Abstract: The invention relates to a hydrokinetic coupling device (10) characterized by the fact that the web (74) comprises, at the inner radial end thereof, a collar (86), which axially extends toward the front between the turbine wheel (32) and the turbine hub (40) and which is rotationally joined by friction welding respectively: at the front, to the turbine wheel (32) by a first weld joint (88) provided between a front annular contact face (90) of the collar (86) and a rear welding face (92) opposite the inner radial periphery of the turbine wheel (32) and; at the rear, to the turbine hub (40) by a second rear weld joint (96) provided between a rear annular contact face (98) of the collar (86) and a front welding face (100) opposite the outer radial periphery of the turbine hub (40).

Abstract: A coupling apparatus for a motor vehicle, including a hub designed to link in rotation an output shaft and a turbine wheel a clutch for locking the coupling between the input shaft and output shaft. A locking piston is axially mobile between a wall integral with the turbine wheel and a wall for locking a crankcase designed rotatable link the input shaft and an impeller wheel. A female member of sealing mechanism, linked to the piston axially about a male member of the sealing mechanism, linked to the hub. A damping mechanism is clamped between the piston and the wall and an output member linked to the hub. The male member and the damping output member are each mounted on the hub or born by a member mounted on the hub.
