Abstract (en)
[origin: WO2016100993A1] What is proposed is a tamping assembly (C, D, E, F) for a track tamping machine having a carrier (4, 18, 23) which is guided height-adjustably with respect to a tamping assembly frame (9, 14) along guides (8, 15, 22), on which carrier pairs of tamping tools designed as oscillating levers (3, 19) are pivotably mounted, the tamping tools (6) of which pairs, which are intended to be introduced into a ballast bed (24), can be oppositely driven by an oscillation drive (7, 17, 20) and can be hydraulically adjusted relative to one another, wherein a plurality of tamping tools (6) are combined to form tamping units (S) which between them leave free a compartment for engaging around a rail and are mechanically connected to one another, and wherein each oscillating lever (3, 19) is assigned a tamping unit (S) and an adjusting drive (5), and wherein the guides (15, 22), in particular guide rods, act directly on the respective carrier (4, 18, 23) and run in fixed guides of the tamping assembly frame (9, 14).
