ABSTRACT:
To couple the initiation and the chronological sequence of a coupling or uncoupling process of a mechanical middle buffer coupling and an electrical cable coupling arranged on it longitudinally displaceably in the direction of the coupling axis with a common rotary drive with the smallest possible amount of control effort and in a reliable manner, a coupling and uncoupling device is provided with a drivable shaft arranged at right angles to the coupling axis. An actuating arm is nonrotatably fastened to the drivable shaft, and the actuating arm extends into a guide rail of the cable coupling and is thus designed as the direct drive member of the cable coupling. The shaft is guided rotatably and longitudinally displaceably in a lower hollow shaft section of a hollow shaft, which consists of a lower, a middle, and an upper hollow shaft section, and the shaft extends beyond the middle hollow shaft section in the upward direction into the zone of the upper hollow shaft section, in which zone the shaft is guided longitudinally displaceably but nonrotatably.
