Abstract
The invention relates to a tamping assembly for tamping sleepers of a track, including a tamping unit having oppositely positioned tamping tools mounted on a vertically adjustable tool carrier, the tamping tools being coupled in each case via a squeezing drive to a vibration drive, wherein each tamping tool comprises a pivot lever rotatable about a pivot axis and at least one tamping tool mount for accommodating at least one tamping tine. In this, a first squeezing drive is coupled directly to the vibration drive and articulatedly connected to a first pivot lever, and a second squeezing drive is coupled to the vibration drive via a separate coupling unit and articulatedly connected to a link, mounted on the tool carrier, as well as to a second pivot lever. In this manner, the tamping unit can be configured in a very compact way with squeezing drives being arranged one below the other, wherein forces and momentums occurring during operation can be easily controlled.
