The invention relates to a hydraulic damping bush (10) with an external bearing piece (11) and an internal bearing piece (12), which are supported against each other by means of a spring body (13a) made from an elastomeric material. The spring body (13a) defines at least one working chamber (14), filled with a hydraulic fluid and connected to at least one equalisation chamber (15), by means of a damping channel (18). The working chamber (14) is provided with a decoupling membrane (16a, 16b), pressurised on both sides by the hydraulic fluid. In order to achieve a decoupling effect up to high frequencies with small physical dimensions, said decoupling membrane (16a, 16b) runs in the circumferential direction and extends radially downwards. The decoupling membrane (16a, 16b) is provided with a decoupling chamber (17a, 17b), offset in the axial direction relative to the working chamber (14). The equalisation chamber (15) runs around the external circumference of the bush (10). |
