Abstract
The invention relates to a hydraulic bearing () with a support spring (), a working chamber () which is at least partly surrounded by the support spring () and which is filled with a hydraulic fluid, a control membrane () which is designed to change a working chamber volume of the working chamber (), and an electromagnetic actuator () for deflecting the control membrane (), wherein the actuator () comprises a stator () and an armature () which can be moved in the longitudinal direction L of the stator (); the armature () is mechanically connected to the control membrane (); the stator () has a stator conductive element () made of a ferromagnetic material; the stator conductive element () has an upper stator collar () which extends in the transverse direction Q of the stator () and a lower stator collar () which extends in the transverse direction Q of the stator (); the armature () has an armature conductive element () made of a ferromagnetic material; the armature conductive element () has an upper armature collar () which extends in the transverse direction Q of the stator () and a lower armature collar () which extends in the transverse direction Q of the stator (); the upper stator collar () and the upper armature collar () face each other; and the lower stator collar () and the lower armature collar () face each other. The control membrane () is designed for a maximum deflection a in the deflection direction of the control membrane, and the mutually facing upper and/or lower collars (or, partly overlap over an overlap length u in the longitudinal direction L of the stator () such that a ratio of the overlap length u to the maximum deflection a lies between 0.1 and 1.5. The invention further relates to a motor vehicle with a corresponding hydraulic bearing ().
