WHEEL MACHINING DEVICE FOR RAILWAY ROLLING STOCK AND METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To generate adhesion necessary between a wheel of a traveling rolling stock and a rail by switching a traveling course of a rolling stock from a first track to a second track by means of a course switching device for giving surface roughness to the tread face of a wheel in a wheel machining part. SOLUTION: A determination unit 12 computes a surface condition of a wheel in a railway rolling stock traveling on a traveling rail 1 on the basis of a detection result given from a first detection unit 10 and a second detection unit 11 so as to determine whether adhesion necessary between the wheel and the rail can be secured or not under the present wheel surface condition as against a weather condition. If it is determined that necessary adhesion cannot be secured, a lead rail 14 is moved so as to guide the railway rolling stock to a second track (wheel machining rail 2), while the railway rolling stock is guided to a first track (traveling rail 1) if it is determined that necessary adhesion can be secured. The railway rolling stock guided to the second track travels on the second track at a low speed. Consequently, an uneven shape of the first rough face in the wheel machining rail 2 is transferred to the tread face of the wheel and surface roughness is provided on the tread face of the wheel.
