Abstract
A hydraulic bearing includes a supporting bearing and a bearing member braced against each other by an essentially truncated conical elastic spring element of an elastomeric material. The spring element bounds a working chamber and a compensating chamber filled with damping fluid, these chambers being separated from one another by a dividing wall and being in fluid communication with one another via a damping channel. The elastic spring element has two compression-spring sections radially opposite one another and two push-action-spring segments radially opposite one another and the compression-spring sections. The supporting bearing radially overlaps the elastic spring element in the compression-spring sections, and the elastic spring element and the supporting bearing are interconnected by a radial surface area. The supporting bearing and the elastic spring element are interconnected in the push-action-spring sections by an axial surface area extending essentially parallel to the axis of the hydraulic bearing.
