ABSTRACT:
A system for connecting a towing, pushing, or hoisting self-propelled vehicle to a non-propelled vehicle utilizes two, three, four or five links connected to each vehicle by respective ball joints. The links converge so that the centers of the non-propelling vehicle's forces and motions can be located at places favorable to the steering, stability, and weight distribution of the two vehicles, usually at or near the center of gravity of the self-propelled vehicle. The locations of steering and carrying centers are determined by point-centers or two- or three-degree-of-freedom linear combinations of line-centers where lines extended from the links intersect in points or lines of intersection. The invention includes apparatus for varying the location of the virtual steering and support centers when the vehicles are at rest or in motion, by changing the separation of the hinge points or ball joints on either vehicle. The invention also includes apparatus for varying the height or lateral location of a trailed vehicle by lengthening the links on the side toward which the trailed vehicle is to be relocated, and conversely.
