New wheels for 25 and 30 tonne axle loads – design, stresses and geometric stability
Conference contribution, 2004

Two freight wheels for 25 and 30 tonne axle loads have been designed. Requirements on the wheels from European point of view, according to CEN and UIC, are discussed along with particular (more strict) requirements on wheels in Sweden, according to SJ. Good performance of the wheels under high thermal loads at gradient braking is at focus. The shrink fitting method is discussed together with the magnetic induction heating method that only heats the hub of the wheel, which is used in Sweden for mounting the wheels onto the axles.
