ABSTRACT:
A powered vehicle of the type which rides on front and rear primary road wheels that are in tandem relationship and located midway between the sides of the vehicle has a body with sides that are convergent in the downward direction enabling a high degree of leaning of the vehicle during turns. At least one auxiliary road wheel is carried at each side of the vehicle by sidewardly extending pivot arms which enable lowering of the auxiliary wheels during low speed travel and when the vehicle is stationary. At the raised position, the auxiliary road wheels extend from the sides of the vehicle in position to ride on the roadbed when the vehicle is tilted sidewardly to an inclination that is more horizontal than vertical. In the preferred form, the vehicle body has an inverted teardrop configuration in cross section and tapering front and back end regions and has an aircraft empennage at the back end. Interlinkage synchronizes raising and lowering of the auxiliary wheels and adjusts wheel camber and steering in the process. Spoiler flaps on the empennage are actuated concurrently with actuation of the vehicle braking system.
