Abstract: A hydraulic damping mount has a working chamber and a compensating chamber, which are filled with a hydraulic liquid and separated from each other by an intermediate plate. The working chamber and the compensating chamber are connected to each other via a transfer passage and a bypass channel. The bypass channel can be opened or closed by an actuator. The actuator is configured as a one-piece elastomer part, which has a fastening portion on the edge and an actuating element, which is connected to the fastening portion via a flexible connecting portion.

Abstract: A mounting bush contains an inner mount part supported by a resilient body made of an elastomeric material. The resilient body is mounted in an outer housing of a mount or on a chassis mounting pad. The resilient body defines at least two air-filled working chambers interconnected by at least one damping channel. The working chambers are low profile and contain a low linear excursion. A ratio of the pumping diameter to a linear excursion of 15 to 80 is provided.
