I’m rigging a vehicle that doesn’t quite behave like a typical train or truck trailer.  And I have a question for the coupling.  The rotations I want are best illustrated in the attached photo.  I want to have a single axis (Y-axis) rotate where the coupling joins the cab and the trailer, and in the center of the coupling, I want to be able to rotate along the X and Z axes, but not the Y.  Does that make sense?

A flexible sheathe will cover the actual coupling, so I’ve been using bones to try to do this which the sheathe will be skinned with.  I just haven’t created a rig that actually bends the way I want it to yet. 

Any ideas?

I will have to give some thought to this. One of the biggest issues will be getting it to trailer correctly and not have the connection pull apart even if it is working correctly. Do you have an image of what this vehicle looks like?
