ADAPTIVE SPRING SUSPENSION OF LOCOMOTIVES

Abstract

The authors describe the design of adaptive torsion spring suspension equipped with adaptive hydro mechanical damper, technique to assess kinematics of straight motion of diesel locomotive bogie equipped with such a spring suspension. According to the results of analytic study conducted by the authors, the use of suggested model allows to considerably reduce amplitudes of car body oscillations and velocity of its drift in vertical plain, as compared to similar production units.
