Abstract

A hydraulically damping rubber bearing has a substantially hollow-cylindrical inner portion and an outer portion disposed with a predetermined spacing relative to the inner portion. A resilient connection portion is disposed between the inner portion and the outer portion and connects the outer portion to the inner portion. The resilient connection portion has a first hydraulic damping circuit with at least two first fluid chambers which are in fluid communication with each other by means of a first flow connection. The first hydraulic damping circuit has a damping action in a predetermined direction. A second hydraulic damping circuit provides a damping action in the same predetermined direction as the first hydraulic damping circuit.
