A tamping unit for tamping a track has tamping tines which are designed for immersion into a ballast bed and which can be set in vibrations by a vibration drive. The vibration drive includes a housing in which a shaft including an eccentric is arranged for rotation about a shaft axis. A transmission element for transmitting a vibratory motion is mounted on the eccentric. The eccentric is connected to the shaft in a rotation-locked and radially displaceable manner, wherein the position of the eccentric relative to the shaft is adjustable in radial direction by an adjustment device. Thus, while retaining the advantages of an eccentric drive, it is possible to adjust vibration parameters during operation.

A mechanism with a base; a pendulum mounted pivotally relative to the base about a pendulum axis; first/second eccentric elements generating first/second moments of gravitational force about first/second axes; and a synchronization system of the first/second eccentric elements according to a synchronized counter-rotating rotational movement. The pendulum axis and eccentric elements' axes are parallel and arranged in the plane integral to the pendulum. The eccentric elements' axes are supported by the pendulum, above and below the pendulum axis. The eccentric elements are movable in synchronized counter-rotating rotation, with cross-centrifugations, the pendulum pivots alternately on one side then the other, amplifying the rotational movement of the eccentric elements, by simultaneous cross-thrusts of the pendulum against the eccentric elements' axes, and by the transmission of torque to the synchronization system, and the energy generated by centrifugation within the mechanism is recoverable by coupling an energy recovery system to the synchronization system.
