Abstract

A hydraulic bearing for supporting an assembly of a motor vehicle includes a carrying bearing portion and a support portion. In embodiments, a working chamber that is fillable with hydraulic fluid is formed in the carrying bearing portion, and a compensating chamber that is fillable with hydraulic fluid is formed in the support portion. A nozzle disc, through which the flow can pass and which delimits the working chamber from the compensating chamber, may be arranged between the carrying bearing portion and the support portion, and a damping duct for the fluidic communication of the working chamber with the compensating chamber may be formed in the nozzle disc. In embodiments, the two chambers, the damping duct, and the hydraulic fluid may form a first damping system for damping vibrations of lower frequencies and a second damping system may be formed for damping vibrations of higher frequencies.
