Title: Articulating mine car coupling

Abstract: An articulating coupling for connecting two wheeled vehicles includes a pivot connection and a tilt mechanism. The pivot connection is provided between the two vehicles so that they can turn relative to each other in the horizontal plane and be selectively turned relative to each other. The tilt mechanism includes a horizontal pivot connection between the two vehicles so that vertical movement of at least a portion of one vehicle adjacent to the horizontal pivot connection will move a portion of the other vehicle adjacent to the pivot connection in the same direction and cause the other vehicle to pivot about the axis of its wheels.
