The invention relates to an elastomeric bushing, preferably provided for use as an axle bearing, having hydraulic damping. As is fundamentally known, said bushing comprises a metal inner piece (1), an elastomeric bearing body (2) surrounding the inner piece (1) with a cage (3) vulcanized therein for reinforcing the bearing body (2), and an outer shell (4) accommodating the inner piece (1) with the bearing body (2). At least two chambers (5) are formed between the bearing body (2), which adheres to the inner piece (1) due to vulcanization, and the outer shell (4) for the purpose of accommodating a fluid damping medium, said chambers being spatially separated from one another in the circumferential direction of the bearing by bars (8) of the bearing body (2), but being connected to one another via a damping medium channel (7). A pretension is applied to the elastomer of the bearing body (2). According to the invention, however, said pretension is not applied via the outer shell (4) of the bearing, as is known, but rather via the cage (3), thus causing a calibration even before the installation of the bearing body (2) in the outer shell (4) by a compressive force applied to the cage, in contrast to the prior art. |
