Hydraulically damping rubber bush bearing has radially inner lying wall of each fluid filled chamber changing from section parallel to bearing axis into section at angle to it, forming undercut in direction of bearing axis

摘要

The hydraulically damping rubber bush bearing has an elastomer bearing component (3) installed between a metal inner section (1) and metal cage (2). The bearing component has fluid filled chambers (4,4'), the radially inner lying wall of each of which changes from a section (7,7') parallel to the bearing axis into a section (8,8',9,9') at an angle to it, forming an undercut (5,5',6,6') in the direction of the bearing axis. The inner cage and elastomer bearing component are axially shortened in the corresponding circumferential section in relation to their remaining circumferential sections.
