Active positioning device for a rubber support (1), comprising a space (3) surrounded by a housing (2), there being arranged within the space (3) a positioning member (4) and a working member (6) configured as a spring element, it being possible to move the positioning member (4) and the working member (6) backwards and forwards in the direction of the vibrations (7) introduced into the rubber support (1), and the positioning member (4) being sealed off relative to the housing (2). The positioning member (4) is formed by a pneumatic spring (8) which can be supplied with pressurised gas, the pneumatic spring (8) comprising at least one piston-cylinder unit (9, 10), which has a rolling diaphragm (11) for sealing off the piston (9) relative to the housing (2). The spring element (5) is formed by a compression spring which is supported, in the direction of the vibrations (7) introduced, on the positioning member (4) on the one hand and on the bearing support (12) of the rubber support (1) on the other and is under elastic prestress. <IMAGE> |
