Abstract

A device is disclosed for mechanical vibration decoupling having two bearing ends to which bodies for reciprocally decoupling vibrations are joined which are interconnected by couplings having a variably adjustable stiffness. The couplings comprise at least three spring beam elements each having a spring beam surface from which a normal vector extends and which are each dimensionally stable in a longitudinal direction and are elastical orthogonal to the spring beam surface. The at least three spring beam elements are disposed spatially relative to each other so that normal vectors thereof are each orientated at an angle α relative to each other with α=90°±30°.
