Abstract

Изобретение относится к области машиностроения, а именно к производству втулок рычажной тормозной системы рельсового пассажирского или грузового транспорта, в том числе вагонов метрополитена, эксплуатирующихся без использования смазки. Техническим результатом является повышение срока службы втулки, повышение стабильности коэффициента трения, повышение разрушающего напряжения при растяжении, сохранение ударной вязкости при одновременном сохранении низкого коэффициента трения и заданного предела прочности при сжатии. Технический результат достигается тем, что втулка рычажной тормозной системы рельсового транспорта выполнена из композиционного полимерного антифрикционного материала на основе полиамида, содержащего в качестве волокнистого наполнителя углеродное волокно или смесь углеродного волокна со стекловолокном. При этом композиционный полимерный антифрикционный материал дополнительно содержит хаотично расположенные углеродные нанотрубки в виде однослойных, многослойных или вложенных друг в друга свернутых в трубку графитовых плоскостей. В качестве основы композиционный полимерный антифрикционный материал дополнительно содержит смесь полиамида с полиэтиленкапроамидом.The invention relates to the field of engineering, namely the production of bushings of the lever brake system of a passenger or freight rail, including subway cars operated without the use of lubricant. The technical result is to increase the life of the sleeve, increase the stability of the coefficient of friction, increase the breaking stress under tension, maintain toughness while maintaining a low coefficient of friction and a given tensile strength in compression. The technical result is achieved by the fact that the sleeve of the lever brake system of the rail transport is made of a composite polymer antifriction material based on polyamide containing carbon fiber or a mixture of carbon fiber with glass fiber as a filler. Moreover, the composite polymer antifriction material additionally contains randomly arranged carbon nanotubes in the form of single-layer, multilayer, or graphite planes rolled into a tube. As a basis, the composite polymer antifriction material further comprises a mixture of polyamide with polyethylene caproamide.
