An arrangement for horizontal central arresting and releasing of an intermediate buffer coupling has a horizontally swingable coupling rod, a guide member at a rear end of the coupling rod and following the swinging of the latter, two rocking levers pivotally mounted on a vehicle and having abutment faces, a roller supported on the guide member and located between the rocking arms so as to abut against their abutment faces, and an actuating device connected with the rocking levers and operative for opening of the latter in the sense of allowing free movement of the intermediate buffer coupling.

Arrangement for arresting and releasing an intermediate buffer coupling

A drive arrangement for transport vehicles is operative for moving a step plate between operative positions so that passenger access to the vehicle is facilitated. The drive arrangement includes a turnable shaft coupled to the step plate, and a motor coupled with the shaft for turning the latter about its axis and for moving the step plate between its operative positions. An uncoupling device disengages the motor from the shaft so that the step plate can be manually moved. The drive arrangement also comprises a switching arrangement having first cam parts spaced from and about the shaft, and second cam parts mounted on the shaft for joint rotation therewith. The second cam parts each have a predetermined angular position relative to the shaft and to the first cam parts for controlling the operation of the motor so that manual movement of the shaft upon uncoupling of the motor therewith forceably positions the second cam parts to retain their respective predetermined positions. Thereby, subsequent actuation of the motor is greatly facilitated.
