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.

Hydraulic bearing with biaxial damping

A rubber bearing for the central pin of a leaf spring suspension in a motor vehicle includes a housing split in an axial plane and of a rubber bushing (1), which is arranged on the pin with radial pretension and includes two half shells (3, 4), which are axially fixed on the pin by at least one radially engaging tongue-and-groove assembly (8, 9), whose abutting surfaces, which are located opposite each other in the assembled state, are at a distance from one another peripherally in the preassembled state. The half shells (3, 4) of the rubber bushing (1) in this rubber bearing are connected to one another at their ends by flexible webs (5) and have recesses (12), which accommodate the webs (5) folding in during the radial compression.
