ROAD-RAIL VEHICLE

摘要

A transport vehicle equipped with a number of first wheel sets, having wheels provided with tires, to which steering means and driving means, if any, are coupled to enable the transport vehicle to be moved over a road surface. The transport vehicle further comprises at least one second wheel set, having rail wheels, which rail wheels can be automatically moved up and down in vertical direction so as to enable, in the lowered position, a movement of the transport vehicle over rails disposed in the road surface, while simultaneously weight-relieving the wheels with tires. The rail wheels have substantially no steering function. A control mechanism steers the wheels with tires, so that the transport vehicle follows the rails. The transport vehicle functions in a transport system, to which every vehicle is welcome, provided that standards regarding driving properties, steering and safety are met. In such a transport vehicle, the respective advantages associated with transport over a road surface and track rails, respectively, are combined, thereby avoiding at least a number of disadvantages exhibited by these modes of transport individually.
