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.

摘要： A hydrokinetic torque coupling device for a motor vehicle comprises an impeller wheel intended to be coupled to a crankshaft and adapted to hydrokinetically rotate a turbine wheel. The impeller wheel rotationally coupled to a cover at least partially accommodating the impeller wheel, the turbine wheel and the reactor. The turbine wheel is axially moves between an engaged position in which the turbine wheel and the impeller wheel are axially moved closer to each other and rotationally coupled together, and a disengaged position in which the turbine wheel and the impeller wheel are axially moved away from each other and rotationally uncoupled. The device comprises a bracing member axially extending between the turbine wheel and a part of the cover, with the bracing member being adapted to limit the axial motion of the turbine wheel toward the above-mentioned part of the cover, opposite the turbine wheel.
