Bogies of the Railway Vehicles with Steered Wheelsets

The paper deals with the issue of the railway vehicle negotiating a curve and the negative effects originating from the conventional structure or design of the bogie. The autors discuss the optimum solution referring to the radial positioning of the wheelsets in negotiating a curve in relation to the centre of the curve. The review of different solutions speaks of the problems resulting from the opposing effects of installation of the flexible elements between the wheelsets and the frame of the bogie in the case of operation on a straight track and negotiating a curve. The most satisfactory results have been reported for the bogie design including the wheelsets steered by the mechanism linking the wheelsets and the body of the vehicle. The utilisation of these bogies eliminates the angle of incidence between the wheels and rails consequently reducing the steering force, loading of the permanent way as well as the wear of wheels of wheels and rails.
