Abstract
A hydraulic damping elastomeric bearing includes an internal element, an external element disposed around the internal element to be radially spaced therefrom, and an elastomeric spring disposed between the internal element and the external element. The elastomeric spring has a cavity therein and defines a sealed boundary of the cavity. The cavity includes at least two chambers for being filled with a damping fluid. A throttling channel is for throttled fluid connection of at least one of the chambers and at least another of the chambers.
