Another Radical Idea

OK, forget the first diagram. I've changed it into a trailer that has freedom of movement only up and down, and left or right. (See permalink #13)

I've abandoned the first idea. See my new diagram at permalink #13

Let's ignore, for the moment, the shell of the trailer. This is the mechanism that will allow the trailer to move both up or down to follow grade changes, and left or right, for turns, and at the same time, without allowing the single wheel to fall on it's side. I was having trouble envisioning how to keep the movement centered on the same vertical line, but I think I have it now:

I'm skeptical. The roll resistance has a 0-length lever arm.

I was having trouble envisioning how to keep the movement centered on the same vertical line, but I think I have it now:

Why? You could have a one foot lever-arm between the horizontal and vertical hinge, with a 16" transition piece. And two hinges widely spaced hinges, both horizontally and verticall, enableing lighter construction.

That would mean a transition piece between the car body roper and the tail, but the gaposis would be on the top at the front and on the sides at the back
