Elastomeric bush bearing with improved torsion characteristic

摘要

The invention is directed to an elastomeric bush bearing. A bearing of this type is substantially unaffected by torsional loads and has a simple design. The proposed bush bearing includes, in a conventional manner, an inner sleeve formed as a hollow cylinder, a sleeve-like outer element surrounding the inner sleeve, and an elastomeric bearing support disposed between the inner sleeve and the outer element. The elastomeric bearing support is formed as two parts, having an inner bearing support and an outer bearing support, with an inner element enclosed between the inner and outer bearing support. For improving the torsion characteristic, the inner bearing support according to the invention is formed by at least one elastomeric formed part which is inserted from one axial end of the support between the inner sleeve and the inner element, which is connected with the outer bearing support. The formed part is held by a pressed-on annular disk, wherein a radially inner region of the disk extends into the inner sleeve forming a press fit. The formed part forms a sliding surface for the inner sleeve and the inner element.
