Abstract

This article examines the selection of optimal springs for freight wagon bogies operating under the conditions of AJ “Uzbekistan Railways”. The technical characteristics of primary load-bearing, secondary (auxiliary), lateral stabilizing, and damping springs used in wagon bogies are analyzed, along with their impact on freight transportation efficiency. Through a comparative analysis of the advantages and disadvantages of various spring types, recommendations are provided for choosing the most suitable option for Uzbekistan’s conditions. The research results aim to improve wagon stability, extend service life, and optimize operational costs.
