  • Patent number: 6637554
    Abstract: A rail brake element, in particular in connection with rail brake buffer blocks, comprising a pair of clamping plates C-shaped in cross section and having upper and lower leg portions, the clamping plates engaging a rail head on opposite sides, at least one braking block element having a flat lower surface which engages the top surface of the rail head and two upper roof-like tapered surfaces, whereby the block element and the brake linings are pressed against the rail head, characterized in that the tapered surfaces of the block element have an angle relative to a horizontal plane of at least 20° and the block element and the clamping plates are dimensioned such that the end of the upper leg portions of the clamping plates have a significant distance from the upper edge of the associated tapered surface if the rail head is not worn.

  • Patent number: 6237726
    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.
