Application of carbon plastic bushes within friction knots of trolley-buses

Abstract

It’s well-known that in comparison with metal works, especially made of expensive nonferrous metals, carbon plastic parts have certain advantages both from technical and economical point of view. That’s why further implemention of these parts in any subfield of engineering is of a great importance, since it allows possibility of recycling and saving huge industrial and financial funds. The most vivid example - production of carbon plastic bushings for pintles of front shaft instead of bronze ones for different models of trolley-buses: UMZ (Southern machine building factory, Ukraine); ZIU (Uritski’s factory, Russia); SKODA (Czech Republic).
