In modern locomotive design to reduce a dynamic effect upon a track there are widely used jaw and lawless six-wheel bogies supplied with a spring suspension using laminated springs, cylindrical spiral springs of compression and pneumatic springs. A considerable drawback of all known designs of spring suspension for rolling-stock is that all of them apart from a pneumatic one have no possibility for self-regulation in an automatic mode of their rigid characteristics de-pending on external dynamic impacts of track unevenness upon the latter. There is developed in Bunin State University of Yelets a promising inventionleveled structure of an adaptive torsion spring suspension excluding such a drawback and a number of computa-tions was carried out for the substantiation its rational design values.
