A three-wheeled vehicle steering and suspension system including two support assemblies for two opposed front wheels pivotably mounted at opposite sides of the vehicle frame and operatively connected by a hydraulic cylinder arrangement actuated by the vehicle steering linkage for inducing opposed pivotal movement of the support assemblies during vehicle turning to cause leaning of the vehicle in the direction of turning. A biasing arrangement provides the operative connection between the hydraulic cylinder and the support assemblies for transmitting lean-actuating reciprocatory movement of the hydraulic cylinder to the support assemblies while yieldably permitting independent pivotal movements thereof. The biasing arrangement may include respective torsion bars fixed at respective ends thereof to the opposite ends of the hydraulic cylinder and at the other respective ends thereof to the support assemblies, the torsion bars being correspondingly rotated by the hydraulic cylinder to actuate the opposed pivotal movement of the support assemblies. A shock absorber is mounted on each torsion bar and extends therefrom to the respective support assembly for dampening independent movements thereof without creating resistance to rotation of the torsion bar by the hydraulic cylinder. Alternatively, the shock absorber may provide the biasing connection between the hydraulic cylinder and the support assemblies. An electro-hydraulic system actuates reciprocation of the hydraulic cylinder in direct relation to the degree of vehicle turning and to the vehicle speed.
