ABSTRACT:
A disc brake for a railway vehicle has a resilient mount for a cross-member upon the ends of which are pivotally mounted brake levers having brake shoes which are engageable with a brake disc mounted on either the wheel or the axle of the railway vehicle. Attached to the cross-piece is a bushing which is supported between two trunion bearings by a bolt passing therethrough. A pair of compressible rubber sleeves are inserted into the bushing to surround the bolt and the outer ends of the sleeves are provided with flanges. A pair of clamping sleeves each having a cylindrical portion are positioned in the trunion bearings and their inner ends are provided with flanges which engage the rubber sleeve flanges. The cylindrical portions have a plurality of axial slots extending from the outer ends thereof and the outer ends of the cylindrical portion have beveled surfaces engaged by corresponding beveled surfaces on washers or other fastener elements such that tightening of the bolt through the bushing will expand the slotted cylindrical portions against the trunion bearings.
