Abstract

A hydraulically damping rubber bush bearing suitable for absorbing cardanic loads in the vertical installed position and yet has a simple geometry and construction. The bearing has chambers receiving the damping agent and has an undercut in the direction of the bearing axis at least in the area of one of their axial ends. An inner cage and the elastomeric bearing body are axially shortened in the corresponding circumferential section compared to the rest of their circumferential sections.
