Abstract
When a railway bogie passes through curved sections of the track, significant pressure forces of the wheel flanges on the outer rail thread arise, which lead to increased resistance to movement and intense lateral wear of the contact surfaces. The reason for this is the formation of large values of the angles of the wheel’s collision on the rails; therefore, to eliminate them, controlled devices are used to ensure the radial installation of the wheelset axes in the curve. However, the shortcomings of the known systems of controlled turning of wheel sets do not allow the full use of such systems on traction rolling stock. To solve this problem, the paper presents a modernized design of the axle box of the electric locomotive. The performance evaluation of the proposed node was carried out according to the results of strength calculations using the finite element method in the most unfavorable operating modes of the box. The analysis showed that the modernized unit meets the requirements for structural strength.
