Abstract (en)

[origin: EP0855327A2] The suspension has a rubber scroll spring with rubber ring (4), positioned on a mandrel (6) and supported against a housing (8). The housing is sealed pressure-tight by a cover plate (20), and thereby a pressure chamber (22) is formed, which can be used as a pneumatic spring. The chamber has an element for pressure level regulation (26), so that the spring/s can be controlled individually or in groups via an electronic control unit. Sensor units (28,30,32) are used to carry out measurements in individual spring elements, for path, pressure and/or vibrations. The resultant signals are processed by an electronic control and regulator device.
