Abstract:
A mobile machine for rehabilitating a track extending in a longitudinal direction, comprising(a) a machine frame extending in the longitudinal direction and supported by at least three sequentially disposed undercarriages for mobility on the track in an operating direction, the machine frame being composed of(1) a leading frame part with respect to the operating direction and(2) a trailing frame part connected to the leading frame part by an articulation,(b) at least one working unit mounted on the machine frame for adjustment relative thereto,(c) a reference system for controlling the position of the working unit, the reference system being arranged on the leading frame part and consisting of(1) a reference line extending in the longitudinal direction between two neighboring ones of said undercarriages,(2) a measuring axle designed to roll on the track, and(3) a measuring device connected to the measuring axle for detecting a movement, transversely to the longitudinal direction, of the measuring axle relative to the reference line, and(d) an angle-measuring device for detecting an actual frame angle enclosed by the leading and the trailing frame part, wherein the angle measuring device is formed by a cable potentiometer, arranged in the region of the articulation and connected to the leading and the trailing frame part, for detecting the actual frame angle enclosed with reference to a horizontal plane.
