Abstract:
1. A hydraulic bearing having a bearing axis, comprising: a supporting bearing having a receiving portion; a bearing base; an annular spring element of elastomeric material interconnecting the supporting bearing and the bearing base; a working chamber and a compensating chamber bounded by the supporting bearing and bearing base and filled with damping fluid; a partition having an opening separating the working chamber from the compensating chamber, the opening connecting the working chamber and the compensating chamber in a fluid-conducting manner; and an annular stop disposed in the working chamber and having an inner peripheral edge, the stop including a supporting body being completely sheathed with a jacket of elastomeric material and the inner peripheral edge being received in the receiving portion and supported by the receiving portion so as to allow movement of the annular stop in an axial direction but not in a cardanic manner relative to the supporting bearing, wherein a ratio of 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, and the supporting body includes at least three stiffening corrugations distributed uniformly in a circumferential direction.
