Abstract
A hydraulic bearing with biaxial damping with an axial and radial damping characteristics essentially independent of one another. The hydraulic bearing including a housing and an axially and radially operating elastomeric damping arrangement received therein. Several chambers are adapted to receive a hydraulic damping device and formed, with respect to the axial and radial orientation of the bearing, in pairs, with each chamber pair interconnected by at least one channel. The upper housing section is constructed as a support body including an inner core, and the outer wall of the upper housing section radially separated from the inner core, and a spring connected with the inner core and the outer wall by vulcanization. The hydraulic bearing is modular, wherein the chambers affecting the radial damping are part of a bush bearing which is inserted in the support body as a separate component and non-positively and/or positively connected thereto.
