Abstract
The invention relates to a rail brake element, in particular for use in rail brake buffer blocks, comprising a pair of clamping plates extending about a rail head from each side and supported against its top surface, which clamping plates are clamped against the rail head by a clamping device including a clamping bolt and a spring assembly, and include at its portion below the rail head a brake lining portion of suitable rigid friction material for engagement with the rail head, wherein the brake lining layer engages the rail head by means of a raised portion of wear material having a static friction coefficient smaller than that of the brake lining layer.
Claims5
A rail brake element, for use in rail brake buffer blocks, comprising a pair of clamping plates extending about a rail head from each side, which clamping plates include at its portion below the rail head a brake lining portion of suitable rigid friction material for engagement with the rail head, a retaining element disposed between the clamping plates and connected to the latter by at least one bolt, which retaining element has at its lower side facing the rail head a plurality of spaced recesses each receiving a spring assembly which is biased by a bolt in the retaining element for urging an element of friction material against the upper face of the rail head so as to exert a tension force upon the clamping plates, characterized in that the retaining element is a lining ledge (32) receiving in said spaced recesses (54) cylindrical pads (50) of friction material, and in that the clamping bolt (60) is hollow and an indicator of rod (66a) extends through the clamping bolt (60) to the pad (50).
