Switchable Hydraulically Damping Bush Bearing

摘要

A hydraulically damping bush bearing is provided with hydraulic area formed from at least two chamber pairs, wherein each chamber pair is formed from at least two separate chambers, which are connected to one another via at least one damping channel. The hydraulically damping bearing with damping in both the axial direction and the radial direction is further improved to the effect that damping or stiffness that can be switched off or on depending on the operating state is also made possible. The hydraulically damping bush bearing ( 1 ) chambers ( 19, 20; 22, 23 ) of the chamber pairs ( 21, 24 ) can be connected via a closable chamber wall opening ( 40 ).
