Title (EN) HYDROKINETIC TORQUE COUPLING DEVICE HAVING TURBINE-PISTON LOCKUP CLUTCH, AND RELATED METHODS
(FR) DISPOSITIF DE RACCORD DE COUPLE HYDROCINÉTIQUE À EMBRAYAGE DE VERROUILLAGE D'ENSEMBLE TURBINE-PISTON, ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) A hydrokinetic torque coupling device includes a casing including a casing shell and an impeller shell, a piston engagement member non-rotatably coupled to the casing and having a first engagement surface, a turbine-piston including a turbine-piston shell partitioning an interior volume of the hydrokinetic torque coupling device into a torus chamber and a damper chamber and including a turbine-piston flange having a second engagement surface movable axially toward and away from the first engagement surface of the piston engagement member to position the hydrokinetic torque coupling device respectively into and out of a lockup mode, and a restricting washer disposed between the impeller shell and the turbine-piston shell for restricting a hydraulic fluid flow into and from the torus chamber for increasing a hydraulic fluid pressure in the torus chamber and pushing the turbine-piston shell toward the first engagement surface of the reaction plate.
(FR) L'invention concerne un dispositif de raccord de couple hydrocinétique comprenant un carter comportant une coque de carter et une coque de roue à aubes, un élément de mise en prise de piston accouplé non rotatif au carter et présentant une première face de mise en prise, un ensemble turbine-piston comprenant une coque d'ensemble turbine-piston séparant un volume intérieur du dispositif de raccord de couple hydrocinétique en une chambre torique et en une chambre d'amortissement et comprenant une bride d'ensemble turbine-piston présentant une seconde face de mise en prise mobile axialement vers et à l'opposé de la première face de mise en prise de l'élément de mise en prise de piston dans le but de placer le dispositif de raccord de couple hydrocinétique respectivement dans un mode de verrouillage et hors dudit mode, et une rondelle de restriction disposée entre la coque de roue à aubes et la coque d'ensemble turbine-piston afin de restreindre un écoulement de fluide hydraulique vers et à partir de la chambre torique afin d'augmenter une pression de fluide hydraulique dans la chambre torique et de pousser la coque d'ensemble turbine-piston vers la première face de mise en prise de la plaque de réaction.
