A hydraulic spring includes hydraulic volumes (4a, 4b). The hydraulic volumes (4a, 4b) are, on the one hand, closed off by a spring element (6) which is vulcanized into an outer ring (8). On the other hand, the volumes (4a, 4b) are delimited by a compensating membrane (10). The volume (4a, 4b) is subdivided by a partition wall (26) into two chambers (4a, 4b), namely, a work chamber (4a), which is next to the spring element (6), and a compensating chamber (4b), which is next to the compensating membrane (10). The partition wall (26) has at least one connecting channel (28) and the chambers (4a, 4b) alternately change in volume and are filled completely with a hydraulic liquid. The partition wall (26) is configured to be flat in order to achieve a damping element requiring only a low structural elevation. The partition wall plane is orientated transversely to the spring axis. At least one level connecting channel (28) extends within the flat partition wall (26). One end of the connecting channel opens into the work chamber (4a) and the other end of the connecting channel opens into the compensating chamber (4b). The at least one connecting channel (28) is preferably configured to have a spiral shape. Several connecting channels (28) can be arranged offset relative to each other in the partition wall (26) and these channels are configured to have a spiral shape. |
