Tamping unit for a track tamping machine
The invention relates to a tamping unit (1) for a track tamping machine, comprising tamping tool pairs, which are arranged on a support (2) that is guided in a tamping unit frame in a height-adjustable manner and which are designed as rocking levers. The lower tamping pick ends (5) of the tamping tool pairs, which lower tamping pick ends are intended to be plunged into a ballast bed (4), can be driven in opposite directions by means of an oscillating drive (6) and can be brought next to each other hydraulically. According to the invention a hydraulic cylinder (11) and a travel sensor (12) for determining the hydraulic cylinder position are associated with each of the tamping tools (3) of a tamping tool pair in order to increase the stability of the tamping unit, wherein the hydraulic cylinders (11) form the drive for bringing the lower tamping pick ends next to each other and the oscillating drive (6) of the tamping tools (3) and the hydraulic cylinders (11) are controlled in dependence on the travel sensor signals.
