The invention relates to a tamping unit (4) for tamping tracks (3), comprising tamping tools (12) which are arranged in pairs and can be adjusted relative to one another by means of respective adjusting cylinders (16), an adjusting piston (17) which can be hydraulically loaded by means of a first hydraulic circuit (23) being arranged in the respective adjusting cylinder (16), and each adjusting cylinder (16) being provided with an oscillating piston (30) which can be hydraulically loaded by means of a second hydraulic circuit (23). The oscillating piston (30) is arranged in a pressure booster (27) having a primary cylinder (28) and a secondary cylinder (29) in order to superimpose vibrations on the adjusting movement (24). In this way, vibrations can be generated with a lower pressure level.
一种用于捣固轨道(3)的捣固机组(4)，其带有成对布置的捣固工具(12)，捣固工具能通过相应的调整缸(16)相对彼此调整，其中，能通过第一液压回路(23)的液压加载的调整活塞(17)布置在相应的调整缸(16)中，并且其中，每个调整缸(16)配有振动活塞(30)，以便将振动叠加到调整运动(24)上，其中，所述振动活塞(30)布置在带有主缸(28)和副缸(29)的增压器(27)中。以此可以通过较低压力水平产生振动。
