Active, hydraulically damping bearing i.e. engine bearing, for motor vehicle, has transmission connected with linear actuator i.e. piezoelectric actuator, and implementing path transmission over incompressibly deformable medium

摘要

The bearing i.e. engine bearing (2), has a working chamber (6) filled with hydraulic fluid and limited by an elastomer component (8). A membrane (10) is suspended such that it is movable in longitudinal direction of the bearing. A transmission (26) stands in connection with a linear actuator (24) i.e. piezoelectric actuator, and with the membrane. The transmission implements path transmission over incompressibly deformable medium. The transmission comprises a piston, which stands in effective connection with the medium.
