Abstract

Embrayage visqueux comprenant un carter d'embrayage prévu pour transmettre un couple de torsion au moyen de surfaces de cisaillement dans une chambre de travail remplie d'un liquide visqueux, qui est séparée par une cloison de séparation, d'une chambre de réservoir pour liquide visqueux.On fait passer la conduite d'amenée (43) au moins le long d'une partie de son étendue longitudinale, à travers une zone (65) dans laquelle on peut produire un champ magnétique à l'aide de l'électroaimant (55) du dispositif de réglage de débit (61). Le liquide visqueux (19) est enrichi en particules magnétisables (69) pour réaliser un mode de fonctionnement magnétorhéologique. On peut ainsi régler le débit entre la chambre de réservoir (21) et la chambre de travail (31).
