Abstract
An elastic connection element with variable rigidity for coupling together components that are spaced from each other. The connection element is a tubular component with coupling points which fix the components to the element. The rigidity of the element, in the state of maximum rigidity, is determined substantially by the coupling points. These are formed by a receiving eyelet and an elastomeric bush bearing press-fit therein. The region located between the coupling points forms a piston/cylinder unit, the interior of which comprises at least two chambers that are separated by the piston and which receive a hydraulic or a pneumatic medium. The chambers are interconnected with one another by a connection line containing a controllable valve. By at least partially opening the valve, the rigidity of the connection element can be reduced in relation to the state of maximum rigidity.
