Switchable, hydraulically damping mount (2), in particular engine mount for a motor vehicle, which comprises the following constituent parts: - a partition (10) which divides a working chamber (6) from a compensating chamber (8), - at least one diaphragm (20) which is arranged in the partition (10) so as to be deflectable in the longitudinal direction of the mount (2), - a switching actuator (30) by means of which the diaphragm (20) can be controlled, wherein in a first state of the switching actuator (30), the diaphragm (20) is fixed in a rest position, and in a second state of the switching actuator (30), the diaphragm (20) is released such that it can perform a movement in the longitudinal direction of the mount (2), wherein in the partition (10) there is arranged a second diaphragm (62) which can be deflected in the longitudinal direction of the mount (2) and which influences the volume of the working chamber (6), wherein between the first diaphragm (20) and the second diaphragm there is arranged an air chamber (64) which, in the first state of the switching actuator (30), is closed off in an air-tight manner with respect to the atmosphere, and which, in the second current-conducting state of the switching actuator (30), is connected to the atmosphere. |
