Abstract
A hydrokinetic torque coupling device includes an impeller, a casing having a first engagement surface, a turbine-piston hydrodynamically drivable by the impeller, and a bearing device. The turbine-piston is axially displaceable into and out of a lockup mode. The bearing device includes a non-axially oriented spring and a substantially incompressible rolling member urged by the spring against an oblique contact surface associated with the turbine-piston to thereby exert a variable axial force against the turbine-piston shell for biasing the turbine-piston out of the lockup mode. The variable axial force exerted by the bearing device against the turbine-piston shell decreases as the turbine-piston is axially displaced towards the lockup mode.
