CURVE PATH OF A SWITCH AND TRACK JOINT USING THIS TYPE OF CURVE PATH

摘要

The invention switch tongue, that on the curve path of a switch comprising a main track and a branch track, curved passage is composed of several gateun different curvatures 1 / R section to the end point of the curve path from the initial point of the curve path and wherein R a represents a radius of curvature, wherein. Curve path (α _A) the initial point and the curve path (α _E) of being chosen so that the radius of curvature α = 1 / R / 1 / R mln ≥ 0 at the end point, α = 1 the point or area where the curve path of the the relative distance from the initial point is positioned at _{ν = L / L ges ≠ 0.5} , where L is a distance L _ges from the initial point of the curve path is the length of the curved passage.
