Abstract
The problem is considered in order to find new solutions to improve the grip of locomotive wheels with rails to increase their traction properties. As a result of the analysis, the possibility is found to increase the traction coefficient by improving the dynamic properties of the carriage part, using the phenomenon of self-oscillation of wheel pairs and the impact of a magnetic field on the contact surface of the wheel and rail. For locomotives with two-axle bogies with a wheel diameter of 1250 mm, it is proposed to use a traction drive with an asynchronous traction motor attached to the bogie frame and an axial gearbox, which allows these methods to be implemented with the existing base of bogies. New traction drive designs are proposed for locomotives with a wheel diameter of 1050 mm.
