TRACK TAMPING MACHINE HAVING SEPARATELY STIMULATED VIBRATING TAMPING PICKS

摘要

A tamping unit of a machine for simultaneously tamping at least two sleepers of a track, positioned one following the other with regard to a longitudinal direction of the machine, includes inner tamping tines provided for simultaneous immersion into the same sleeper crib and, arranged at either end, a respective outer tamping tine. Each tamping lever mounted on an assembly frame for pivoting about a pivot axis is connected to a squeeze drive. Each squeeze drive is mounted on a common eccentric shaft having an eccentricity with respect to an axis of rotation. The eccentricity causing vibrations of the inner tamping tine is configured differently as compared to the eccentricity causing vibrations of the outer tamping tine.
