Title
(EN) DISCONNECTABLE COUPLING WITH LUBRICATION CONTROL
(FR) ACCOUPLEMENT DÉSOLIDARISABLE À COMMANDE DE LUBRIFICATION
Abstract
(EN)
A disconnectable coupling device (11) rotatable about an axis is provided with a first shaft (13) having an end and a hub (31) formed on the end, the hub (31) including a flange extending radially from the end and a round wall projecting axially from the flange and defining a hollow; a second shaft (15) aligned with the first shaft (13) and opposed to the end of the first shaft (13), the second shaft (15) having a drum (37) overhanging the hub(31); a multi-plate clutch (48) held between the hub (31) and the drum (37) to disconnectably connect the hub (31) with the drum (37); a cup (19) so fixed with the hub (31) as to define a gutter (21) around the first shaft (13); and one or more perforations (23) axially passing through the flange to establish fluid communication between the gutter (21) and the hollow.
(FR)
La présente invention concerne un dispositif d'accouplement désolidarisable (11) pouvant se mettre en rotation autour d'un axe et comprenant un premier arbre (13) ayant une extrémité et un moyeu (31) formé sur l'extrémité, le moyeu (31) comprenant une bride s'étendant radialement à partir de l'extrémité et une paroi ronde faisant saillie axialement à partir de la bride et définissant un creux ; un second arbre (15) aligné avec le premier arbre (13) et opposé à l'extrémité du premier arbre (13), le second arbre (15) ayant un tambour (37) surplombant le moyeu (31) ; un embrayage à disques multiples (48) maintenu entre le moyeu (31) et le tambour (37) pour raccorder de manière désolidarisable le moyeu (31) au tambour (37) ; une coupelle (19) fixée au moyeu (31) de façon à définir une gouttière (21) autour du premier arbre (13) ; et une ou plusieurs perforations (23) traversant axialement la bride pour établir une communication fluidique entre la gouttière (21) et le creux.
