Railway vehicle with force transmission link

摘要

The vehicle has at least two coupled carriages (1,2) with at least one pair of force transmission devices between them. Each device consists of a spring (3a) and a damper (3b) on one carriage connected by a cable (3c) passing around a roller (3d) on that carriage to a fixing point on the adjacent carriage. The relative movement of the carriages at their coupling puts a force into the cable and is modified by the action of the spring and damper to the benefit of passenger comfort. The force transmission device can be applied horizontally in a similar way between carriages.
