Изобретение относитс к железнодорожному транспорту и касаетс способов повышени т гового усили локомотивов за счет повышени сцеплени колеса и рельса.The invention relates to railway transport and relates to methods for increasing the locomotive tractive effort by increasing the adhesion of the wheel and the rail.
Известен способ повышени т гового усили локомотива, преимущественfно электровоза, заключающийс в том, что через поверхность контакта колеса и рельса пропускают т говой ток 1.There is a method of increasing the locomotive tractive effort, mainly an electric locomotive, which consists in that a traction current 1 is passed through the contact surface of the wheel and the rail.
Недостатком известного способа вл етс низкое сцепление колес с рельсами.The disadvantage of this method is the low adhesion of the wheels to the rails.
Цель изобретени - увеличение сцеплени колес с рельсами.The purpose of the invention is to increase the adhesion of wheels to rails.
Дл достижени цели весь т говой ток пропускают через поверхность контакта с рельсом колес первой по ходу колесной пары, электрически изолированной от корпуса локомотива.To achieve the goal, all the traction current is passed through the surface of contact with the rail of the wheels of the first along the wheel pair, electrically isolated from the locomotive body.
В нормальном режиме работы электровоза , когда не требуетс дополнительного сцеплени колес с рельсом, т говый ток пропускают через поверхности контакта с рельсами колес всех колесных пар.In the normal mode of operation of an electric locomotive, when no additional coupling of the wheels to the rail is required, the traction current is passed through the contact surfaces with the rails of the wheels of all wheel pairs.
При необходимости увеличени сцеплени колес с рельсами весь ток пропускают через поверхностьIf it is necessary to increase the adhesion of the wheels to the rails, all current is passed through the surface.
контакта с рельсом колес первой по 1СОДУ колесной пары. В результате чего плотность тока в контакте этой колесной пары с рельсом возрастает, что способствует очистке поверхностей контакта, а,следовательно, возрастанию силы сцеплени .contact with the rail of the wheels of the first on 1SODU wheel pair. As a result, the current density at the contact of this wheel pair with the rail increases, which contributes to the cleaning of the contact surfaces, and, consequently, to an increase in the traction force.
Дл обеспечени повышени сцеп,10 лени при движении электровоза в обратном направлении, весь т говый ток пропускают через зону контакта с рельсом, соответствующей первой по ходу колесной пары (бывшей в вом случае последней).To ensure an increase in coupling, 10 laziness when the locomotive moves in the opposite direction, all the traction current is passed through the zone of contact with the rail corresponding to the first along the pair of wheels (the latter in the latter case).
Описанный способ позвол ет значительно увеличить сцепление колес локомотивас рельсами.The described method allows to significantly increase the traction of the wheels by locomotives with rails.
