Method and apparatus for control and regulation of a vehicle chassis

A spring strut including a work cylinder with a slider in the work cylinder. Electrical contacts are applied on the slider and cylinder and in an inward stroke, a first electrical loop, which extends via the slider, is electrically closed and a second electric loop is broken. In an outward stroke, the second electric loop is closed via the slider, and the first loop is opened. Thus, with the aid of an electrical circuit, it is simple and easy to recognize whether the work cylinder is operating in an inward or in an outward stroke.

Spring strut with a relative motion indicative signal

A pneumatic suspension intended for motor vehicles that is equipped with an additional volume. An adjusting piston defining the additional volume separates two work chambers from one another, which can be disconnected from one another or made to communicate with one another via a connecting line and a valve assembly in the connecting line. When the work chambers are in communication, the spring rate of the suspension is variable without force.
