Full-complement multi-directional coupling

摘要: A multi-directional coupling (10) consists of a tubular slipper (14) between member (12) and race (16), there being engageable friction surfaces (20, 36) on the facing bearing (18, 22) defining therebetween channel (28) with pockets (28a) receiving roller members (30), an actuator (e.g. tooth (30)) engaging recess (40) in (14), or spigot pin(s) cam to provide two, three four different modes operation lock-up, freewheel both directions, one direction and/or other).
