ARTICULATED POWERED RAIL CARS FOR LOCAL TRAFFIC, IN PARTICULAR STREETCAR LINES

摘要

The invention relates to an articulated streetcar train of two or more rail cars, in which the bogies are attached below each rail car centre in order to avoid having the bogies below the articulation point. As a result all bogies may be of the same type of construction. As second suspension between the car bodies and the bogies there is a rubber or pneumatic shock absorber, which is desired in such a way that it exerts horizontal recuperating forces in order to deflect the car bodies laterally in such a way that they follow the envelope curve when travelling around a curve. This invention permits all the car bodies to be designed as identical modules; the bogies may be carrying and/or powered bogies, and the need for guidance means for the car bodies is eliminated.
