The quasislip forces are modelling as a nonlinear functions from relative wheel slip.The analytical dependence of motion critical velocity conicality of profile is obtained. It is shown that the additional zones of contact between the rail and rim flange may by appeared (occurrence of holding constraint) for motion with supercritical velocities.
