A multi-directional coupling (10) consists of a tubular slipper (14) between a tubular member (12) and a race (16), there being engageable tubular friction surfaces (20, 36) on the slipper (14) and the race (16), and facing bearing surfaces (18, 22) on the tubular member (12) and the slipper (14) defining therebetween a channel (28) with pockets (28a) receiving roller members (30), there being an actuator (e.g. a tooth (30)) on the tubular member (12) engaging a recess (40) in the slipper (14), or a spigot or a pin(s) or a cam engageable with the slipper (14) to provide two, three or four different modes of operation (e.g. lock-up, freewheel in both directions, freewheel in one direction and/or the other).
L'invention se rapporte à un manchon multidirectionnel (10) comprenant un patin tubulaire (14) disposé entre un élément tubulaire (12) et un anneau (16), des surfaces tubulaires (20, 36) de mise en prise par frottement recouvrant le patin (14) et l'anneau (16), ainsi que des surfaces d'appui opposées (18, 22) recouvrant l'élément tubulaire (12) et le patin (14) et délimitant conjointement un canal (28) situé entre ces deux pièces et comportant des poches (28 a) destinés à accueillir des galets (30), un actionneur tel qu'une dent (30) sur l'élément tubulaire (12) rentrant dans un enfoncement (40) dans le patin ou un ergot ou une (des) broche(s) ou une came mise en prise par le patin (14) pour permettre deux ou trois, voire quatre modes de fonctionnement différents (p.ex., verrouillage, roue libre dans les deux sens, roue libre dans l'un des sens et/ou dans l'autre).
