In an automotive suspension, a supporting member supporting a wheel hub is connected mechanically to a frame of a car to move in a vertical direction with respect to the frame; movement of the supporting member in the vertical direction is opposed by a spring-shock absorber assembly connected mechanically on one side to the frame of the car, and on the other side to the supporting member by means of a coupling device of variable geometry, which is controlled selectively by an actuator for varying the geometry of the coupling device in such a manner as to vary a suspension ratio between vertical movement of the supporting member and a corresponding variation in length of the spring-shock absorber assembly.
