Изобретение относитс к железнодорожному транспорту, а именно к конструкции упругих колес подвижного состава.The invention relates to railway transport, in particular to the design of elastic wheels of rolling stock.
Известно упругое колесо железнодорожного подвижного состава, содержащее обод с кольцевым выступом на внутренней поверхности, ступицу с кольцевым выступом на внешней поверхг ности) прижимной диск и упругие элементы , выполненные в виде резиновых колец, размещенных между ступицей и ободом l .The elastic wheel of the rolling stock is known, containing a rim with an annular protrusion on the inner surface, a hub with an annular protrusion on the outer surface) pressure plate and elastic elements made in the form of rubber rings placed between the hub and the rim l.
Однако в результате передачи значительной статистической радиальной нагрузки в резиновых элементах вследствие релаксационного эффекта возникают необратимые деформации, что ведет к по влению эксцентриситета и неизбежному при этом ухудшению динамики колеса, а также к уменьшению срока службы упругих элементов и колеса в целом.However, as a result of the transfer of a significant statistical radial load in rubber elements, irreversible deformations occur as a result of the relaxation effect, which leads to the appearance of eccentricity and an inevitable deterioration of the wheel dynamics, as well as a decrease in the service life of the elastic elements and the wheel as a whole.
Цель изобретени - повышение срока службы упругого колеса.The purpose of the invention is to increase the service life of the elastic wheel.
Поставленна цель достигаетс тем, что колесо снабжено дополнительными упругими элементами, выполненными в виде металлических пружин, установленных радиально М2ЖДУ ободом и ступицей параллельно резиновым кольцам.The goal is achieved by the fact that the wheel is provided with additional elastic elements made in the form of metal springs installed radially M2zhdu rim and hub parallel to the rubber rings.
