Abstract:
The invention relates to spring elements and bearings which contain these spring elements, the spring stiffness of the bearings and spring elements being individually adjustable by deformable elastomer bodies or elastomer layers by prestressing. The deformation of the elastomer layers and hence of the spring elements is achieved by an appropriately designed hydraulic device. The leak-tightness of the spring elements and bearing elements according to the invention is achieved through special hydraulically prestressed sealing elements, use of a pressure membrane and special structural features of the elastomer elements.
