Abstract
A central buffer coupling for rail-mounted vehicles has a coupling shaft (1) and a drawgear (2) comprising a bearing bracket (4), whereby the rear end (3) of the coupling shaft (1) is connected to the drawgear (2) and coupled to the car body of the rail vehicle via the bearing bracket (4) of the drawgear (2) so as to be horizontally pivotable. The drawgear (2) includes a shock absorber (5, 8), wherein the shock absorber (5, 8) is configured such that upon the exceeding of a definable critical impact force being transmitted through the coupling shaft (1) to the drawgear (2), the connection between the drawgear (2) and the coupling shaft (1) is disengaged and the coupling shaft (1) is at least partially removed from the power flow transmitted to the drawgear (2).
