A decoupler for coupling/decoupling drive between a power train output and road wheels or marine drive means in an amphibious vehicle, is integrated with a constant velocity joint, saving space, weight, and cost for low productions volumes, and simplifying mounting arrangements. Power train output shaft (14) enters casing (12) through aperture (16), and terminates in a flange (20) with splines (22). Baulk ring (50) and synchrocone (48) provide synchromesh action between drive ring (24) and driven CV joint cap (44). Rod (30) is attached to selector arm (28), located in slot (26), allowing coupling and decoupling by an external control, which may be assisted by a pneumatic or hydraulic cylinder (not shown). Fig. 2 shows the coupled state. The synchronmesh parts may be sourced from truck gearboxes. CV joint (34) is mounted in bearings (36), and may be a Rzeppa type. Groove (59) allows fitment of a conventional dust gaiter (not shown): |
