Amphibious vehicle comprising an improved decoupler
First Claim
1. An amphibious vehicle comprising a power train and a decoupler for coupling/decoupling drive between an output from the vehicle power train and a component to be driven, the coupler including an input means, an output means and means for coupling drive between the input means and the output means characterised in that the decoupler further comprises a synchroniser to synchronise the speed of the input means and the output means when drive between the output and input means is being coupled, and in that the decoupler forms part of an integrated unit also comprising a constant velocity joint.

Abstract
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 production volumes, and simplifying mounting arrangements. Power train output shaft enters casing through aperture, and terminates in a flange with splines. Baulk ring and synchrocone provide synchromesh action between drive ring and driven CV joint cap. Rod is attached to selector arm, located in slot, allowing coupling and decoupling by an external control, which may be assisted by a pneumatic or hydraulic cylinder. The synchromesh parts may be sourced from truck gearboxes. CV joint is mounted in bearings, and may be a Rzeppa type. Groove allows fitment of a conventional dust gaiter.
