Abstract
In a sleevelike hydraulically damping rubber bearing with at least two hydraulic working chambers, at least one throttle duct for the damping of vibrations of low amplitudes and one bypass duct for opening the bearing for shock amplitudes are provided. In order to improve the impermeability of the bearing to low disturbing noises, the natural resonance, typically located in the subacoustic range for such bearings, can be shifted into a frequency range around 200 Hz by the insertion of an uncoupling element.
