FIELD: railway transport. ^ SUBSTANCE: proposed wheelset consists of axle with press-fitted wheel centers and tires. Tire consists of two rings fitted on wheel center and provided with end face circular clearances relative to each other. One of clearances is air gap, and the other accommodates rings made of diamagnetic material. One of tire rings is furnished with curvilinear section pins rigidly secured in mating holes made in other ring of tire. Induction coils are fitted on each pin. Windings of coils located in zone of wheel-to-rail contact are connected to dc supply source in series through current collectors when locomotive moves off. Said dc source is located on locomotive. ^ EFFECT: increased wheel-to-rail adhesion coefficient. ^ 3 dwg |
