Abstract

A central buffer coupling for coupling a first rail car body with a second, adjacent rail car body of a multiple-unit rail vehicle, has a coupling head pivotally connected by a coupling shaft to a linking housing of the rail car body, and a pivoting unit pivoting the coupling shaft. The pivoting unit has a guide participating in horizontal pivoting of the shaft that runs about a vertical pivot axis. Pressure surfaces symmetrical to the longitudinal axis of the shaft which correspond to a respective pressure device, bring about horizontal re-centering of the shaft. The respective pressure devices are supported on the linking housing of the shaft to bias the related pressure surfaces against the guide. The guide is positionable with the action-linked coupling shaft in every position of the planned pivot region, via an activation device. In order to have the pivoting unit not be in engagement during traveling operation and thereby be unaffected by pivoting-out movements of the coupling shaft, the activation device pushes a guide pin guided by way of a contour into a guide driver. Because the driver is then connected with the bearing pin, the coupling shaft pivots.
