RAIL FASTENER Russian patent published in 2000 - IPC

FIELD: railway transport; permanent ways. SUBSTANCE: proposed device has two arm members and flexible rail clamp. Arm members are arranged opposite to each other so that rail foot can be placed in between and are provided with thrust surface pointed downwards. Intermediate part of clamp supports thrust surface. End part of clamp passes inside from thrust surface and it is made for flexibly thrusting against upper side of foot to preclude vertical displacement of rail. Outer part of clamp passes in direction from thrust surface at side bending over arc in outer direction and downwards in direction of lower part. Lower part of clamp is made for thrusting against bearing surface in zone displacement in side inner direction from center of curvature of clamp outer part. EFFECT: improved distribution of stresses in clamp, facilitated mounting of clamp. 8 cl, 30 dwg
