Abstract
An apparatus for controlling the spring firmness of road vehicles is proposed, which is combined with a control of the shock absorber firmness. Both controls are performed using a single control valve. Trigger signals for the control valve are ascertained by means of an electronic device, which receives its signals from sensors, disposed on the vehicle, for spring travel, acceleration, vehicle speed and steering angle or the like, and in particular for the travel sensor, which picks up the shock absorber compression and emits it as a signal to the electronic device, with the goal of bringing about a change in the spring stiffness.
