Abstract
A dual-mode twin-chamber thrust bearing having hydraulic damping has a working chamber and an equalizing chamber, which are separated by a partition. The chambers are hydraulically connected by a damping channel or optionally by other vibration-damping devices. The partition is provided in its center with a passage that is closable by an actuator, and the outer wall of the equalizing chamber formed by an elastic bellows. The actuator and the elastic bellows form an integral component, which is displaced by an electric motor via an actuator mechanism.
