A three-wheeled vehicle steering and suspension system includes two support assemblies for two opposed front steerable wheels, the support assemblies each having a tubular housing welded to the vehicle frame, a cylindrical tube rotatably supported within the housing and a cylindrical rod slidably supported within the rotatable tube. Each rotatable tube is affixed at its outer end to the upright support assembly for one of the vehicle wheels and at its inner end to a shock-absorbing member for biasing the wheels into road contact and permitting independent movements thereof to adapt to road undulations. Each sliding rod is affixed at its outer end to the vertical turning shaft of the upright support assembly of one of the wheels and at its inner end to a reciprocal steering linkage for actuating synchronous turning movements of the wheels. In one embodiment, the shock absorbers are connected to opposed crank arms on a connecting shaft arrangement which is drivenly connected to the steering linkage for actuating opposed upward and downward vertical movements of the steerable wheels for causing leaning of the vehicle frame and body upon each turning movement thereof in the direction of vehicle turning.

In a wheeled vehicle of the type having a vehicle frame, two steerable wheels mounted on opposite transverse sides of said frame, and at least one wheel mounted on said frame at a longitudinal spacing from said steerable wheels, an improved steering and suspension means for said steerable wheels of said vehicle comprising: (a) respective support means for said steerable wheels pivotably mounted independently at said opposite sides of said frame about respective generally horizontal axes, each said support means including tube means rotatably supported generally horizontally on said frame to define the respective said horizontal axis and support arm means fixed to said tube means and operably connected to the respective said steerable wheel for vertical movement of said support arm means and the respective said steerable wheel integrally with rotational movement of said tube means; (b) respective resilient biasing means affixed independently to said tube means for movement integrally with rotation thereof and operatively connected to said frame for urging the respective said support means and the respective said steerable wheel into an equilibrium position vertically with respect to said frame and for yielding to permit independent pivotal movement of the respective said support means and corresponding vertical movement of the respective said steerable wheel; and (c) steering means for controlling synchronous corresponding turning movement of said steerable wheels about respective generally vertical axes generally perpendicular to said horizontal axes, said steering means including connecting means operatively connected respectively to said steerable wheels for reciprocatory movement for actuating said turning movement thereof, said connecting means including rod means supported co-axially within said tube means for longitudinal reciprocal movement therein for actuating said turning movement of said steerable wheels.
