Embodiment Construction

[0030] For the convenience of the reader, the same or similar elements have the same reference numerals throughout the group of figures.

[0031] In the following, when referring to vertical and horizontal, front and rear or up and down, this must be explained with reference to the vehicle in its normal operating position.

[0032] figure 1 A tram 1 is shown comprising front and rear passenger cars 2 and 3 connected to, for example, an intermediate passenger car 34 and two intermediate passenger modules 35 . When the tram 1 moves in the direction V, the rear of the front passenger car 2, the rear of the middle passenger car 34 or module 34, or the rear of one of the middle passenger modules 35 is connected to the rear passenger car 3, the middle passenger car 34 or the middle Adjacent front of passenger module 35 . As desired, the tram may consist of only a front passenger car 2 connected to a rear passenger car, either directly or via an intermediate passenger module 35, th...

Abstract

The invention relates to an aisle bellows (4) comprising an outer bellows (6) having a corrugation (33) forming a plurality of valleys (8) each having an upwardly facing valley top portion (13) and connected at each end to a valley top angle (14) forming a connection between the valley top portion (13) and a respective bellows side (15). The channel bellows further comprises at least one drainage channel (12) such that liquid accumulated into at least one of the valley top portions (13) flows along the respective bellows side (15) through the at least one drainage channel (12).

Description

technical field [0001] The present invention relates generally to the field of passenger car construction, and in particular to the field of trams and light rail vehicles. [0002] More particularly, the present invention relates to gangway bellows for interconnecting passenger cars, and particularly the drainage of rainwater that accumulates on the roof and on the gangway bellows along the vehicle. Background technique [0003] In mainline vehicles such as commuter passenger cars or light rail vehicles such as subway cars, two adjacent railway cars are mechanically connected by a coupling. Each adjacent railway car has a cantilevered half-bridge, which together form a channel bridging two adjacent cars to enable passengers to move from one car to the other. The bellows surrounding the cantilevered half-bridge are fastened to each car so that when connecting the cars, the bellows of the cars facing each other are pressed against each other and form a closed bellow. Thereby...
