Slidable railway carriage door operating mechanism - has two piston-cylinder units coupled by roller in sliding plate

摘要

The railway carriage door operating mechanism has a piston-cylinder unit (28) whose piston rod is linked to the door via an arm (32). The cylinder of the unit is supported by a pivoted arm, and a roller (40) is slidable in a slotted arm (26) connected to the rod (24) of a second piston cylinder unit (23). The end of the unit (23) has a follower slidable in a slot (22) and is connected to a pivoting plate (8) by a curved arm (20). The plate (8) has rollers (15, 18) slidable in a track (13), the plate being part of an assembly forming a support for the door (2).
