Abstract

L'invention concerne un treuil/palan qui peut être utilisé dans de petites embarcations en mer ou à terre (voilier ou analogues, par exemple). Ce treuil/palan comprend quatre principaux éléments: une unité à tambour muni d'un cylindre à tambour rotatif conçu pour porter et enrouler un ruban, une corde, un câble, ou analogue; un bloc moteur; un groupe d'engrenages muni d'une pluralité de trains d'engrenages; et un ensemble de couplage comprenant un élément de désacouplement et un système d'entraînement réversible. Le bloc moteur (4) et l'ensemble de couplage (6) sont disposés à l'intérieur du cylindre à tambour (21) et le groupe d'engrenages est placé hors du châssis du treuil. L'ensemble de couplage comprend un élément de désacouplement, une bague de couplage à ressort de rappel (25) présentant des têtes axiales (43, 44, 45, 46) et, entre ces têtes, des espaces accueillant des chevilles (39, 40, 41, 42) montées axialement à la périphérie d'un support à tambour externe (23) portant le cylindre à tambour (21), la bague de couplage (25) ainsi qu'une roue dentée de couplage (22). Les chevilles (39, 40, 41, 42) sont conçues pour entrer en prise entre les têtes (43, 44, 45, 46), dans la bague de couplage (25), afin d'entraîner le cylindre à tambour (21) dans deux directions sélectives. Entre la face inférieure (47, 48) des têtes (43, 44, 45, 46), la bague de couplage (25) présente des surfaces de guidage (49) conçues pour guider les chevilles (39, 40, 41, 42) vers, par exemple, la position de désacouplement (50).
