Abstract (en)
[origin: WO2009124543A1] The invention relates to an elastic connection element with variable rigidity for connecting mutually spaced components. The connection element is designed as a tubular component with coupling points (1, 1') for fixing to the components to be connected to said element. According to the invention, the rigidity of the element in the state of maximum rigidity is determined substantially by the coupling points (1, 1'). These are formed by a receiving eyelet (3, 3') and an elastomeric bushing (4, 5, 4', 5') pressed therein. The region situated between the coupling points forms a piston-cylinder unit (6, 7), the interior of which comprises at least two chambers (9, 9'), separated by the piston (7), for receving a hydraulic or pneumatic medium. The chambers are interconnected by a channel or a connection line (10) containing a controllable valve (11). By at least partially opening the valve, the rigidity of the connection element can be reduced in relation to the state of maximum rigidity.
