Abstract

A hydraulic bearing includes a supporting bearing, a bearing base, and an annular spring element of elastomeric material interconnecting the supporting base and the bearing base. A working chamber and a compensating chamber are bounded by the supporting bearing and bearing base and filled with damping fluid. A partition having an opening separates the working chamber from the compensating chamber. The opening connects the working chamber and the compensating chamber in a fluid-conducting manner. An annular stop is disposed in the working chamber and is movable relative to the supporting bearing in an axial direction. An inner peripheral edge of the annular stop is received in a receiving portion of the supporting bearing. A ratio of a thickness of the inner peripheral edge in the axial direction and a height of the receiving portion in the axial direction is 0.5 to 1.
