ABSTRACT

Purpose: To determine vertical load changes transmitted from two-axle locomotive bogie wheel-sets to the rails at the torque development in traction electric motors that deteriorate the wheel-rail adhesion. To achieve the set goal, a design model have been performed and the starting torque developing during the electric motor traction transmission have been defined. This torque is expressed through the interaction forces of the traction elements transferred to the bogie frame and to the wheelset axles. To determine the vertical force changes from each wheelset to the rails due to the action of the traction motor torque. Methods: Application of the theoretical mechanics laws; formulation and solution of equilibrium equations. Results: In a locomotive two-axle bogie, consecutive wheels bear contrarily directed loads of the same magnitude. Particularly, for 2(3) ES5K electric locomotives, such redistribution of vertical loads will amount to 3.1% of the axle load. Practical significance: The research results can be used for the development of automatic control systems for wheel-rail adhesion.
