Abstract
A device for elastically supporting the coupling shaft (4) of a central buffer coupling at a rail-borne vehicle with a spring apparatus is provided, which is formed by rings (9) arranged one behind another at mutually spaced locations in the longitudinal direction of the coupling shaft and vertically. The pretensioned rings (9) are held in annular rings (5, 6) of the coupling shaft (4) and of the housing (3). To improve the generation and the adjustability of the pretension of the spring apparatus of the device, the coupling shaft (4) has a collar (11), with which a pretensioning ring (12) is in contact with its rear side, on the one hand, and, and with which the ring (9) located closest to the opening of the housing (3) is in contact, on the other hand, with its front side, wherein the pretensioning ring (12) pretensions the rings (9) in the longitudinal direction of the coupling shaft (4) in the unloaded state of the device.
