| Abstract. The article presents the results of the two-year observed operation of the flexible tram wheel tyres of the SAB type for new types of trams operated in Poland. The chemical composition of the rim material, their microstructure and hardness were initially checked. During the operation, covering the mileage of 70,000 km, every 10,000 km the diameter of the rolling circle of the wheels D and the parameters of the rim profile, e.g. flange height (Sh), flange width (Sw) were measured. Every 30,000 km, the wheel rims were reprofiled by machining on a track bed lathe, in accordance with the requirements of the tram maintenance system. |
