摘要： A hydrokinetic torque coupling device includes a casing having opposite sidewalls and an outer wall extending between and connecting the opposite sidewalls, an impeller coaxial aligned with the rotational axis, a piston engagement member extending substantially radially inward from and non-moveable relative to the outer wall of the casing, and a turbine-piston coaxially aligned with and hydrodynamically drivable by the impeller. The turbine-piston includes a turbine-piston shell having a turbine-piston flange with an engagement surface that is movable axially toward and away from an engagement surface of the piston engagement member to position the hydrokinetic torque coupling device into and out of a lockup mode in which the turbine-piston is mechanically locked to and non-rotatable relative to the piston engagement member.

摘要： A hydrokinetic torque converter including a secondary piston for purposes of enhancing operation of the lock-up feature, and the method of operating such a converter. The secondary piston moves axially behind the turbine-piston to urge respective lock-up clutch friction surfaces into phased engagement. In an initial phase of engagement, friction surfaces between the secondary piston and turbine-piston engage to begin the reduction of relative rotary motion between the converter impeller and turbine-piston. This initial phase of slowing relative movement between the impeller and turbine-piston reduces pressure within the torus and the associated fluid forces separating the friction surfaces of the lock-up clutch. The secondary piston also slows and eliminates fluid flow from within the torus past the lock-up clutch and further reduces engagement resistance of the lock-up clutch owing to the lessening fluid pressure and flow. A more consistent lock-up clutch engagement, with higher torque capacity, is provided in both driven and coasting lock-up operation.
