ABSTRACT:
An active positioning element for a rubber mount, including a space surrounded by a housing, a positioning member and a working member which is designed as a spring element arranged within the space. The positioning member and the working member are movable back and forth in the direction of oscillations introduced into the rubber mount, and the positioning member is sealed in the housing. The positioning member is formed by a gas pressure spring which can be acted on by gas under pressure, the gas pressure spring comprising at least one piston-cylinder unit which has a roller membrane for sealing the piston off from the housing. The spring element is formed by a compression spring which, in the direction of the oscillations introduced, rests under elastic initial stress, on one side against the positioning member and on another side against the support bearing of the rubber mount.
