Automatic train coupling

Abstract

The invention relates to an automatic train coupling, in particular for a freight wagon of a rail vehicle, comprising: a coupling head which comprises a coupling head housing and a coupling fastener having a lock, the coupling fastener being designed as a rotary fastener having a coupling link and a central part, the central part being rotatable about a main axis between a couple-ready position, a coupled position and an uncoupled position, the coupling link being connected at a first end to the central part so as to be rotatable about a coupling link axis and having a second free end; and the central part having an opening which is arranged for receiving a second end of a coupling link of a diametrically opposed coupling head, and the central part being rotatable against the force of a spring-loaded accumulator from the coupled position into the uncoupled position and by way of the force of the spring-loaded accumulator from the uncoupled position into the coupled position; a lubrication device by means of which lubricant can be supplied to at least one lubricated point in the coupling head, wherein the lubrication device has one or more lubricant channels in the coupling head. The automatic train coupling is characterised in that at least one lubricant channel extends through the central part.
