Thread: Coupling for powered trailers

I know nuffink about autos and VCs so laugh at me if i'm way off the mark

Edit: I could be thinking of fluid couplings or torque converters or something...

How about a freewheel unit from an old 80'' Landy t/case in the propshaft line to the diff? Lockable for reversing or creeping down steep gradients, but when unlocked the vehicle can drive the trailer, but the trailer can't overun the vehicle, except from the force of gravity, which even happens with unpowered trailers anyway.

A couple of pics posted by a AULRO member some time ago.
