Abstract

Железнодорожная грузовая тележка имеет надрессорную балку и пару боковин, причем надрессорная балка установлена поперечно относительно боковин. Установочная поверхность между концами осей и буксовыми челюстями боковин обеспечивает качание боковин аналогично тележкам с люлечным подвешиванием. Поперечное качание сочетается со способностью к продольному самоподруливанию. Способность к самоподруливанию может быть получена путем применения продольных качалок, которые обеспечивают сопротивление отклонению, пропорциональное нагрузке на сопряжение. Тележка может иметь вспомогательные центрирующие элементы, установленные в гнездах буксовой челюсти, и эти вспомогательные центрируемые элементы могут быть выполнены из упругих эластомерных материалов. Тележка также может иметь фрикционные гасители колебаний, не склонные к скачкообразному движению. Гасители колебаний могут быть снабжены тормозными накладками или подобными элементами, установленными либо на гранях, сопрягаемых со стойками боковин, либо на наклонной грани, либо на обеих поверхностях. Силы трения, возникающие при перемещении фрикционных гасителей колебаний вверх и вниз, могут быть не равны. Фрикционные гасители колебаний могут располагаться в виде четырехугольника на каждом конце надрессорной балки. Рессорные комплекты могут включать подгруппы пружин различной высоты.Railway cargo trolley has a bolster and a pair of sidewalls, with the bolster installed transversely relative to the sidewalls. The mounting surface between the ends of the axles and the side-axle box jaws provides for the sidewalls to swing in the same way as trolleys with hanging arm. Cross swing is combined with the ability for longitudinal self-steering. The ability to self-twist can be obtained by applying longitudinal rockers that provide resistance to deflection proportional to the load on the mate. The cart may have auxiliary centering elements mounted in the sockets of the box jaw, and these auxiliary centering elements may be made of elastic elastomeric materials. The cart may also have friction dampers that are not prone to abrupt movement. Vibration dampers can be equipped with brake linings or similar elements mounted either on the faces mated to the sidewall struts, or on the inclined face, or on both surfaces. The frictional forces that occur when moving friction dampers up and down may not be equal. Friction dampers can be located in the form of a quadrilateral at each end of the bolster. Spring sets may include subgroups of springs of different heights.
