Device for suspending a steerable wheel

Vehicle suspension

The vehicle suspension system enables an improved linear relationship between a vehicle wheel's jounce and rebound travel and a spring's compression and extension by the positioning of an outboard bell crank (7) in a vertically oriented plane perpendicular to the longitudinal axis of a vehicle chassis (24). The bell crank (7) is pivotally connected by a vertical link member (5) to the outer end of an upper control arm (3). Wheel movement is linearly transferred directly from the bell crank (7) to a spring assembly (10). Alternatively, a horizontal link member may be used to transfer wheel movement to the spring assembly.
