eng	Modelling of flexi-coil springs with rubber-metal pads in a locomotive running gear	Nowadays, flexi-coil springs are commonly used in secondary suspension stage of rail vehicles. Because it is often suitable to modify their lateral stiffness in such way, that the suspension shows various stiffness in different directions (i.e. especially a minimization of resistance against bogie rotation, which is closely related with lateral force interaction between the vehicle and the track, at preservation of lateral stiffness of the suspension), the springs are supplemented with rubber-metal pads. This paper deals with modelling of flexi-coil springs supplemented with rubber-metal tilting pads applied in running gear of an electric locomotive as well as with consequences of application of that solution of the secondary suspension from the point of view of running and guiding performance of the vehicle. This analysis is performed by means of multi-body simulations; description of lateral stiffness characteristics of the springs is based on results of experimental measurements of these characteristics performed in heavy laboratories of the Jan Perner Transport Faculty of the University of Pardubice.	flexi-coil spring; tilting rubber-metal pad; lateral stiffness; suspension of railway vehicle; rail vehicle dynamics; multi-body simulation
