The proposed mathematical model is derived from the known dependences defining interaction of an elastic wheel with deformable bearing surface, considering differences determining the conditions of the second axle wheels rolling moving in the tracks of the front axle wheels. The mathematical model allows by certain vertical load on the carriage, longitudinal velocity and angular velocity of the wheels to determine the longitudinal force component transmitted to the vehicle frame and the total torque realized by the carriage wheels on interaction with the supporting surface.
