Wear-resistant railway wheel rim profile


For use in existing or prospective freight cars with constant contact skates, for operating conditions on the railways of Ukraine, the CIS countries and the Baltic States with a gauge of 1520 mm.


Railway transport.


The increase in the resource of a wheel with the proposed rim profile (in terms of flange wear) compared to a wheel with a standard profile (GOST 9036-88) by 4–5 times, which significantly reduces the intensity of contact surface wear, increases the resource of wheels for regrinding (in terms of flange wear) up to 3 -400 thousand km.


Using a profile allows you to increase the size of the contact patches and ensure conformal contact of the wheel with the rack.
