Freight car stable bogie includes the cross bearer extending into side frame and supported therein. Spring set rests in every end of cross bearer. Every side frame features availability of horn gap at every end to support pivot unit so that elastomer guide pad and bearing adapter are strutted. Side frame and cross bearer fastening assembly is composed of a stiff hinge joint. Friction wedges between side frames and bolster allows damping from damping at low friction level to high friction level at engagement.EFFECT: hinge uncoupling of side frame and cross bearer as well as crosswise displacement of friction wedges to bolster decrease interaction of displacements caused by track shifts.10 cl, 7 dwg
