A two-chamber step bearing with hydraulic damping especially for mounting engines of motor vehicles is presented. It has at least one fluid-filled working chamber and at least one compensating chamber connected to same by a nozzle channel of variable cross section. The cross section of the nozzle channel is changed by means of a first motor-powered actuating drive. The working chamber is provided with a buckling spring, which is integrated in its walls and whose stiffness can be changed by means of a second motor-powered actuating drive. The second motor-powered actuating drive is independent from the first actuating drive. Due to the described design embodiment the two-chamber step bearing can be continuously adapted during the operation of the two-chamber step bearing to both the damping of low-frequency vibrations of large amplitude and the damping of high-frequency vibrations of small amplitude. The bearing is an especially compact and inexpensive design.
