The present invention relates to a central buffer coupling ( 1 ) having a coupling head ( 2 ), a coupling shaft ( 3 ) and a bearing block ( 4 ) attachable to the front face of a car body, wherein the coupling shaft ( 3 ) comprises a front shaft component ( 5 ) supporting the coupling head ( 2 ) and a rear shaft component ( 6 ) coupled to the bearing block ( 4 ) so as to be horizontally pivotable which are pivotable in the horizontal plane relative one another about a rotational axis (Z) defined by a connecting pin ( 7 ), and wherein the central buffer coupling ( 1 ) further comprises a pivoting mechanism ( 10 ) to pivot the front shaft component ( 5 ) relative the rear shaft component ( 6 ). With the objective of simplifying the overall structure of such a central buffer coupling, the invention provides for the pivoting mechanism ( 10 ) to comprise a slotted gate ( 11 ) fixedly attached to one of the two shaft components ( 5; 6 ) and having a sliding guide ( 12 ), a cam disc ( 21 ) rotatably mounted about the rotational axis (Z) defined by the connecting pin ( 7 ) and having a cam disc guide ( 22 ), and a bolt ( 30 ) connecting the one to the other of the two shaft components ( 6; 5 ), the first end of which is received in a bolt guide ( 31 ) in the sliding guide ( 12 ) and its second end in the bolt guide ( 31 ) in the cam disc guide ( 22 ) in each case such that upon rotation of the cam disc ( 21 ) about the rotational axis (Z), at least a portion of the resulting torque can be transmitted from the cam disc ( 21 ) to the slotted gate ( 11 ) via the bolt ( 30 ).
