  • Patent number: 7441759
    Abstract: An elastomeric bush bearing is designed as a slotted bush. To reach a high ratio of static radial stiffness to torsion spring rate along with a high axial stiffness at the same time, a beading is formed at least at one axial end but preferably at both axial ends of the slotted bush. In case of an especially advantageous embodiment, a slotted bush with additional intermediate parts inserted into the elastomeric bearing body, two encapsulated rubber packets are created by the simultaneous special geometric design of the inner part. The individual stiffnesses of the two rubber packets are thus compensated and thus there is a homogeneous increase in the overall stiffness of the bush. The beadings are prepared before the components of the bearing are assembled and vulcanized to the parts of the later outer sleeve.
