Abstract

Mécanisme d'accouplement commandé par la vitesse notamment pour un dispositif hydrodynamique. Le mécanisme d'accouplement selon la présente invention est prévu pour accoupler la turbine et la roue à aubes d'un dispositif hydrodynamique et comprend un disque 42 fixé à la turbine comportant des rampes 56 réalisées dans des ouvertures d'un disque 42, des mécanismes de mâchoires de friction 44 montés dans ces ouvertures et prenant appui sur les rampes 56 par l'intermédiaire d'un galet 72. Les mâchoires 60 viennent en contact avec la roue à aubes 22 à une vitesse de rotation prédéterminée de la turbine et les rampes assurent un accouplement des mâchoires avec la roue à aubes. Des ressorts 62 retiennent les mécanismes de mâchoires dans les ouvertures. Application à un mécanisme d'accouplement utilisable notamment pour accoupler ou désaccoupler la turbine et la roue à aubes d'un conertisseur de couple hydraulique.Coupling mechanism controlled by the speed in particular for a hydrodynamic device. The coupling mechanism according to the present invention is provided for coupling the turbine and the paddle wheel of a hydrodynamic device and comprises a disc 42 fixed to the turbine comprising ramps 56 made in openings of a disc 42, mechanisms friction jaws 44 mounted in these openings and bearing on the ramps 56 by means of a roller 72. The jaws 60 come into contact with the impeller 22 at a predetermined speed of rotation of the turbine and the ramps ensure coupling of the jaws with the paddle wheel. Springs 62 retain the jaw mechanisms in the openings. Application to a coupling mechanism which can be used in particular for coupling or uncoupling the turbine and the paddle wheel of a hydraulic torque converter.
