Hydraulic bearing for supporting an assembly of a motor vehicle

A hydromount for mounting a powertrain unit of a motor vehicle, comprises:

• a carrier mount portion and a support portion, wherein a working chamber for a hydraulic fluid is formed in the carrier mount portion and a compensation chamber for a hydraulic fluid is formed in the support portion, wherein between the carrier mount portion and the support portion a nozzle disc permits flow and delimits the working chamber from the compensating chamber, wherein the nozzle disc includes a damping channel for fluidic communication of the working chamber with the compensation chamber, wherein the working chamber, the compensating chamber, the damping channel and the hydraulic fluid form a first damping system for damping vibrations with lower frequencies, wherein a second damping system is formed for damping vibrations with higher frequencies, wherein the second damping system has an overflow connection between the compensation chamber and an absorber channel to absorb idling vibrations, and wherein a plunger is accommodated in the absorber channel, the plunger movable axially along a longitudinal axis of the hydromount, the plunger aiding in opening and/or closing the absorber channel.
