Track surfacing machine and method for correcting the track geometry based on track cant and measured lining force

摘要

A track surfacing machine for correcting the track geometry includes a machine frame supported by undercarriages for mobility in an operating direction and including lining drives for correcting the track in a direction transversely to the track and measuring carriages rolling on the track and provided with measuring instruments. The measuring carriages form with the machine frame as well as with measuring instruments a reference system for detecting the actual track geometry, with the machine frame defining a reference base. Associated with the forward and rear measuring carriages of the reference system in operating is a measuring unit for detecting a cant or lateral inclination of the track, with a pressure pickup being provided for determining the lining forces of the lining drives.
