Abstract

<b> </b>In this article questions on creation and calculation of a perspective design of adaptive torsion suspension for the locomotives, including hydromechanical dampers of fluctuations of adaptive type. The design procedure of the main kinematic and geometrical characteristics on a locomotive example 2Ð¢Ð10Ð, supplied with the specified technical solutions, and studying of fluctuations and power loading of its running gears is offered. Thus, the dynamic settlement scheme on the basis of Foygt-Kelvin's elastic and viscous model is developed. The bench pilot studies, allowed to specify parameters and characteristics of the above-stated designs are carried out. Expected economic effect of possible introduction of development will make 850 thousand rubles a year on one locomotive. Materials of this article were discussed at various conferences of leading higher education institutions of the Russian Federation. Results of researches are recommended to design, research and machine-building structures for their possible use in practice.

Highlights

Modern rolling stock, including loco motives, passenger and freight cars is the most important constituent part of the technical facilities of railway transport characteristics, properties and parameters of which are determined by the growth of traffic, increase traffic speed, ensuring operational reliability, increase the comfort of passengers and the smooth progress of railway carriages, cargo safety, etc
The existing design elements spring suspension of rolling stock have a number of drawbacks, such as a high metal content, complexity of design, low reliability and, most importantly, the inability to change in the automatic mode of their damping characteristics
Today in the framework of the research developed a promising adaptive torsion suspension, designed for the main and industrial loco motives, including adaptive hydro-mechanical dampers, established on the level of inventions (RU2427737 and a positive decision of FIPS fro m 25.04.2012, according to the application No2011121597/11), schematic diagram of which is shown in figure 1

Summary

Introduction

Modern rolling stock, including loco motives, passenger and freight cars is the most important constituent part of the technical facilities of railway transport characteristics, properties and parameters of which are determined by the growth of traffic, increase traffic speed, ensuring operational reliability, increase the comfort of passengers and the smooth progress of railway carriages, cargo safety, etc. Such requirements are d irect ly connected with the imp rovement of their spring suspension, aimed at reduction of dynamic loads transmitted fro m the track of the body and crews and increasing the smoothness of the rail vehicles. The existing design elements spring suspension of rolling stock have a number of drawbacks, such as a high metal content, complexity of design, low reliability and, most importantly, the inability to change in the automatic mode of their damping characteristics
