Abstract

See full text

A boltless fastener assembly for a heavy haul railway with an axle load of 35-40 tons includes a pre-embedded steel holder, an e-clip, an insulated gauge block and a rubber pad. A clamping leg-heel end of the e-clip is provided with an L-shaped retaining end. The pre-embedded steel holder is improved to adapt to the e-clip, and an opening is formed at a portion of the pre-embedded steel holder close to the clamping leg-heel end of the e-clip, so that the e-clip can be installed normally. During normal installation, the L-shaped retaining end of the e-clip does not contact the pre-embedded steel holder. When the rail undergoes large torsional deformation, the L-shaped retaining end on one side of a rail moves upward to contact an upper edge of the opening of the pre-embedded steel holder or engages with a second heel end.
