Active hydraulic damping engine mount for motor vehicle, has intermediate plate that is located between working chamber and compensating chamber through bypass, so that intermediate plate is oscillated

摘要

The hydraulic damping engine mount comprises rubber-elastic chamber wall (6) that is surrounded by working chamber (2) and compensation chamber (3), which are filled with hydraulic fluid. An intermediate plate (4) is located between working chamber and compensating chamber through bypass (5), so that intermediate plate is oscillated. An annular piezo-actuator element (11) is located on a surface of intermediate plate.
