Abstract
The invention relates to an assembly bearing with hydraulic damping, especially for supporting engines and/or gearboxes in motor vehicles. Said bearing comprises a working chamber (10) and a compensation chamber (20) which respectively have partially elastically deformable walls (30, 40) and are separated by a dividing wall (50), but interconnected by means of a damping channel (60) through which a fluid is guided, in addition to another passage opening (14) which can be variably adjusted from outside. According to the invention, a decoupling device for insulating high-frequency, low-amplitude vibrations is provided in the dividing wall (50), the other passage opening (14) being arranged upstream or downstream of said decoupling device.
