The paper describes the development of the form of auto-oscillations in case of rotation of the traction unit which is affected by a combination of random conditions and the development of rotation, the effects of shock vibrations in operation, the presence of subharmonic resonances and external disturbances at frequencies close to auto-oscillations. Due to the fact that the self-oscillations of a pair of wheels are the most typical form of self-oscillation for known drive structures, in order to reduce the self-oscillations to a safe level, it is proposed to use energy dissipation on impacts in the transmission gear.
