Switchable hydro mount

Switchable hydraulic bearing for mounting of a motor-vehicle assembly, comprising:

• a support bearing and a mount, which are connected to one another by a support spring, and a working chamber and an equalization chamber, which are able to be filled with damping liquid and, at their sides facing axially towards one another, are spatially separated from one another by a separating wall and are connected to one another in a liquid-conducting manner by a damping channel included in the separating wall,
• wherein the separating wall comprises a nozzle cage with first and second nozzle discs which are provided adjacent to one another with an axial spacing, wherein a diaphragm composed of a rubber-elastic material is provided in a gap formed by the axial spacing between the nozzle discs, and wherein the diaphragm is switchable by a switching device;
• and wherein the switching device comprises an elastic lever disc, which is provided axially adjacent to the second nozzle disc and able to act thereon, and an electromagnet, which is connected to the lever disc and can selectively adjust the lever disc between a first position, in which the lever disc permits axial play of the diaphragm in the gap, and a second position, in which the lever disc acts on the second nozzle disc and clamps the diaphragm between the nozzle discs.
