ABSTRACT:
A hydraulic bearing, having a working chamber filled with a damping fluid and a compensating chamber. The chambers are separated from one another by a dividing wall and are in fluid communication with one another via a damping channel, to damp low-frequency vibrations. The damping channel is formed by two subchannels which, in terms of technical function, are arranged in a series connection. The subchannels are arranged axially on both sides of a diaphragm that is capable of vibrating. The diaphragm forms a component of the dividing wall, and the diaphragm is provided with a channel separation and has at least one opening within the channel separation for fluid communication of the subchannels with one another.
