Abstract

Изобретение относится к области железнодорожной техники и имеет отношение к автосцепным устройствам железнодорожных вагонов, в частности к конструкции когтя (кулака) автосцепки и к способу его изготовления. Коготь железнодорожной сцепки содержит носовую часть, хвостовую часть, соединяющий их переходный участок и внутреннюю полость, при этом толщина стенок когтя в зоне внутренней полости в переходном участке выполнена однородной, при этом хвостовая часть в зоне тяговых поверхностей выполнена с неравномерной толщиной стенок и площадкой с верхней стороны, при этом отверстия для валика сцепки и сигнального флажка выполнены в виде двух параллельных между собой отверстий, не связанных между собой. Способ изготовления когтя железнодорожной сцепки включает в себя выполнение верхней и нижней полуформ и литейных стержней, установку литейных стержней между полуформами с их последующим соединением, заполнение полученной литейной формы металлом, при этом литейные стержни устанавливают между верхней и нижней полуформами на расстоянии друг от друга для формирования отверстий и внутренних полостей когтя отдельно друг от друга. Заявляемое изобретение позволяет оптимизировать и повысить надежность конструкции когтя железнодорожной сцепки и упростить технологичность способа изготовления.The invention relates to the field of railway technology and relates to automatic couplers of railway cars, in particular to the design of the clutch (fist) of the automatic coupler and to a method for its manufacture. The claw of the railway hitch contains a bow, a tail, connecting their transition section and the inner cavity, while the wall thickness of the claw in the zone of the internal cavity in the transition section is uniform, while the tail part in the zone of the traction surfaces is made with uneven wall thickness and the platform with the upper sides, while the holes for the hitch roller and the signal flag are made in the form of two holes parallel to each other, not connected to each other. A method for manufacturing a clutch of a railway coupling includes performing upper and lower half-molds and casting rods, installing casting rods between the half-molds with their subsequent connection, filling the mold obtained with metal, the casting rods being installed between the upper and lower half-molds at a distance from each other to form openings and internal cavities of a claw separately from each other. The claimed invention allows to optimize and improve the reliability of the construction of the claw of the railway coupling and to simplify the manufacturability of the manufacturing method.
