Vehicles e.g. tram-car, connecting device for use in railway system, has joint wings arranged at each vehicle as upper articulation, where joint wings in one vehicle is connected to joint wings in another vehicle by non-supported bearing

摘要

The device has a joint rod (3) for connecting vehicles (1, 2) as lower articulation, and joint wings (4a-4d) that are rotatably arranged around vertical axes (5a, 5b) at each of the vehicles (1, 2) as separate upper articulation. The joint wings (4a, 4b) in the vehicle (1) is rotatably connected with the joint wings (4c, 4d) in the vehicle (2) by non-supported bearing (6a, 6b), so that the four joint wings form a variable parallelogram.
