Vehicle with combined propulsion and steering mechanism

A vehicle comprising the combination of:

• a frame, two laterally spaced right and left front wheels and at least one rear wheel, means supporting the wheels to rotate relative to the frame about generally horizontal axes, and means supporting the front wheels to steer about generally vertical steering axes;
• a column and means supporting the column relative to the frame for oscillation about a laterally extended pivot axis, and means operatively coupling the column, at locations spaced from the pivot axis thereof, to the rear wheel, operable for powering the rear wheel upon column oscillation relative to the frame;
• and
• a steering member rotatably mounted within the column and presenting an arm, and elongated laterally extended rigid right and left links connected pivotally at inboard ends thereof to the steering member arm at locations having a radially spacing from the column and connected at outboard ends thereof to the respective right and left front wheels, operatively joining the front wheels to the steering member;
• the inboard link ends moving along an arcuate path concentrically of the column, upon steering member rotation in steering the vehicle;
• said arcuate path and said column pivot axis being located relative to one another to provide that said pivot axis generally intersects the arcuate path at two spaced intermediate axis-path intersections symmetrically disposed generally of a midpoint position of the steering member when oriented to provide for straight ahead vehicle movement.
