HYDRAULIC MOTOR BEARING

摘要

The invention relates to a hydraulic motor bearing, in particular for motor vehicles, comprising a working chamber (4) which is filled with a liquid and which is surrounded by a rubber-elastic periphery wall (3), a compensation chamber (7) which is connected to the working chamber (4) by means of a overflow channel (6) in the separating plate (7) between the working chamber (4) and the compensation chamber (7), and an additional compensation chamber (10) which is connected to the working chamber (4) by means of a bypass channel (9). The additional compensation chamber (10) is formed from an elastic body (11) which is surrounded on the external side thereof by a solid wall (12). An intermediate chamber (13) is arranged between the body (11) and the wall (12). Said intermediate chamber can be filled with a compressible medium, preferably air, and said medium can be removed. The inventive switch device is formed from at least one return valve (14) and at least one switch valve (15), whereby the return valve (14) is arranged in a ventilation channel as a connection path between the intermediate chamber (13) and the external side of the solid wall (12) in such a manner that only the medium, which is located in the intermediate chamber (13), can flow to the external side of the wall (12) and the switch valve (15) is arranged on the ventilation channel (17) as an additional connection path of the intermediate chamber (13) between the external side of the motor bearing. Said ventilation channel (17) can be open or closed.
