Abstract
A hydraulically damped rubber bearing has a working chamber defined by a rubber-elastic spring member, a bearing member, a journal bearing, and an end wall, which is flexibly movable in the direction of the working chamber. The end wall is provided with an elastic suspension mount that can be forced into abutment with a stop surface in dependence upon predetermined parameters. The suspension mount is connected directly to the journal bearing and the stop surface is formed as a rigid part of the journal bearing. A control device selectively permits free movement of the end wall when acoustically disturbing vibrations are introduced into the bearing.
