WHEELS PROFILE FOR RAILWAY VEHICLES, SUCH WHEEL AND RAILWAY VEHICLE WITH SUCH WHEEL

摘要

FIELD: transport.;SUBSTANCE: invention concerns a wheel profile for a rail vehicle, wheel with such a profile and rail vehicle with such wheel. Wheel profile for a rail vehicle, which has substantially constant ratio of wheel camber to the rail profile curvature while the interaction with the profile rail in each point of wheel profile contact with the rail profile. On the FIG. 1 the profile has a form, which has corresponding points of the wheel profile surface with the coordinates Y and Z as shown in Table 1.;EFFECT: invention provides a creation of the wheel profile, which has a higher running performance at high speeds and enhanced wear characteristics.;3 cl, 1 dwg, 1 tbl
