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).
