ABSTRACT:
A three wheeled vehicle has a steered front wheel and two driven rear wheels. A novel suspension has inner and outer members keyed to rotate in lockstep, but to accommodate axial travel of only the inner member. The inner member rises and falls with the front wheel as the vehicle negotiates uneven terrain, and the outer member is axially immobilized. Steering inputs are imposed on the outer member, which passes rotational movement to the inner member. The novel suspension incorporates a spring and shock absorber, and enables steering linkage to avoid vertical displacement imposed upon the suspension. In various embodiments, the vehicle accommodates one, two, or three passengers, and includes open or fully enclosed bodies.
