Abstract: A steerable control system for roadable vehicles includes an axle 16 having rotatably mounted wheels 14a and 14b upon the respective ends thereof. These wheels each include a king pin assembly 60 connected to the axle ends by a pair of king pins 76. Nested within a tapered hole 78 through a spindle member 70 in each of the king pin assemblies 60 is a tapered section 36 of a steering arm 32. A control arm portion 46 of each steering arm 32 is angled outward and backward from the tapered section 36 and generally toward a well of the adjacent wheel 14a or 14b. Attached to the perforate ends 50 of the arms 32 are the ends 86 of a tie rod 30 such that lateral movement of the tie rod 30 causes the arms 32 to rotate the wheels 14a and 14b upon the axle 16, the result being a tighter turning radius with a truer wheel rolling motion than in standard steering systems.
