ABSTRACT:
The object of the invention is a diaphragm for passsenger railway cars, which consists of a platform (5) and a diaphragm (36, 2, 3) disposed in tunnel fashion over the platform. The system is so constructed that it provides good protection for the interior against external influences even when the differences in pressure between the outside and inside are extreme. The tunnel-like diaphragm consists of an inner end frame (36) for fastening to one of two railroad passenger cars coupled together, an outer end frame (3) for cooperation with the outer end frame of the connecting platform of the second of two coupled railroad passenger cars, and a resilient member, especially a bellows (2) between the two end frames (36) and (3). The outer end frames (3) is suspended by springs (4a) directly on one of the two passenger cars, and the springs exert an outwardly directed force on the outer end frame (3). The connecting platform is made in two parts, of which an inner part (9) is fastened to one of the two passenger cars to be coupled together, and the other, outer part (6a) is displaceably supported at the read end on the inner part, is joined to the outer end frame ( 3) at the front end, and terminates in the same vertical cross plane as the outer end frame. The outer end frame is provided with a thrusting surface (4, 4b), so that, when two passenger train cars are coupled together, the connecting platforms and the shelter of the two diaphragm systems will abut one another face to face and be held in contact with one another by the springs (4a) so that no fasteners are needed, and yet the junction between the two diaphragms is sealed off, even when allowable lateral shifting between the two diaphragms takes place. The diaphragm and platform are sealed against one another. The outer end frame (3) is of a tunnel-like configuration, and its relatively long side walls have flaps in the front, lower region, which close openings, into which the platform of a second passenger train coupled to the first can enter when this platform deviated from the platform of the other car such that it enters in the form of a plate into the diaphragm system of the first car and rests upon its connecting platform.
