Abstract

An automatic central buffer coupling for rail vehicles has a coupling head (1) with a projection (25), a hook (3) mounted on a fixed pivot bearing (4) in the coupling head for swinging in a coupling position, an articulated arm mechanism (10, 11, 12, 13, 14) mounted in the coupling head and spring means (17, 19; 18, 20) acting on the hook (3). The articulated arm mechanism comprises a first articulated arm (10) which is pivotally connected to a second pivot bearing (12) defining a fixed axis of rotation with respect to the coupling head, wherein the hook (3) is connected by means of a pivot joint (13) to a second articulated arm (11) which is connected by means of a second pivot joint (14) to the first articulated arm (10) whose movement is limited by a wall (28) or stop provided with the coupling head. In the coupling position of the hook (3) the axes of rotation defined by the first and second pivot joints (13, 14) and the second pivot bearing (12) are intersecting an arc-shaped line (30) and the articulated arm mechanism is pressed by means of a spring means (17, 19) against the stop or wall (28) of the coupling head, wherein the spring means is supported on a supporting bearing (21) located on the concave side of the arc-shaped line (30).
