Abstract

The transition coupling for rail vehicles has an automatic coupling head 7 which is displaceable relative to a coupling arm 1 and can be locked by a locking mechanism 4, 21 in its rear position, which can be adjusted against the force of a spring device 24. Furthermore, a coupling member 12 is provided which is longitudinally displaceable relative to the coupling head 7 and can be locked in its rear position by a further locking mechanism 15, 20. In the respective front positions, if there is longitudinal coupling play, simple coupling of the coupling head 7 to an automatic matching coupling head or manual coupling of the coupling member 12 to a hook coupling on a matching vehicle is possible. The locking mechanisms 15, 20 and 4, 21 can be operated by turning a hand lever 22; they automatically engage at the appropriate turned position of the lever 22 under the gravitational load of the same as soon as the coupling head 7 or the coupling member 12 are in the respective rear position. During engagement, the locking mechanisms 15, 20 and 4, 21 respectively slightly exceed a dead-centre position. For easy, manual disengagement, the engagement points of the locking mechanisms can be displaced in an at least roughly frictionless manner past the dead-centre position by common movement of the engaging parts of the locking mechanisms. During tensile loading of the coupling head or the coupling member 12, the further disengagement operation is thus effected by auxiliary labour with only a slight expenditure of force. <IMAGE>
