- the transmitted over Beistellzylinder and Pickelarme on the tamping Vibration movement thus remains largely unaffected by the resistance of the ballast bed.
- Vibratory motion generated by means of a hydraulic linear drive Without special measures here leads to an increased ballast bed resistance to an undesirable reduction of the vibration amplitude.
- a hydraulic linear drive allows easy adjustment of the vibration parameters up to a rapid sequence of inputs and
- the invention has for its object to provide an improvement over the prior art for a vibration drive of the type mentioned. Another task is a
- the eccentric is rotationally connected and radially displaceable connected to the shaft, wherein the position of the eccentric relative to the shaft in the radial direction by means of an adjusting device is adjustable.
- a torque is transmitted by means of the shaft on the eccentric designed as a separate component.
- the effect on the transmission element determines an adjustable center distance between an eccentric axis and the shaft axis.
- Shaft axis not only leads to an altered vibration amplitude, but at constant torque also to a changed impact force, which is applied by means of the vibration drive.
- Transmission element as a connecting rod for transmitting an oscillating
- Vibratory movement is formed.
- the connecting rod is then connectable to a linear guided piston, by means of which the vibration is transferable to several components.

- the flattenings form a positive connection together with correspondingly executed mating surfaces of the eccentric in order to securely transmit a torque.
- the adjusting device at least one
- the hydraulic cylinder is arranged in the shaft.
- This cylinder is connected to a guided in the shaft hydraulic line, so there is a compact and weight-saving design of the adjusting device.
- the hydraulic cylinder is by means of a
- the adjusting device comprises a further cylinder with a piston for fixing and / or for returning the eccentric.
- the eccentric is thus clamped in its position between two pistons, whereby a particularly robust fixation is given.
- the second piston is favorably controlled by means of a pilot-operated check valve.

- Eccentric axis comprises. In this way is verifiable, whether a

- vibration drives can be operated synchronized in this way.
- a simple drive variant provides that the shaft is connected to a variable hydraulic motor.
- the shaft is connected to a variable hydraulic motor.
- a simple adaptation of a vibration frequency is possible by the rotational speed of the shaft is changed.
- the shaft is coupled to a flywheel.
- the flywheel serves as a buffer to compensate for these energy fluctuations.
- the method is further developed in such a way that a
- Stuffing cycle is formed of several successive phases running and that by means of a control and / or regulation at least in one phase compared to another phase different center distance between the shaft axis and an eccentric axis is set.
- Individual phases of the Stopfzyklus form, for example, a lowering of the
- Stopfaggregats and a repositioning of Stopfaggregats Due to the adjustability of the vibration drive for each phase is optimally used.
- a center distance equal to zero is set in order to suspend the vibration independently of the rotational speed of the shaft for a desired duration. This is particularly useful during a repositioning of the tamping unit between two stuffing operations for noise reduction and to reduce the power consumption of the vibration drive.
- the shaft is driven at different speeds.
- the vibration frequency is adaptable to different requirements during a stuffing cycle.
- FIG. 2 Vibratory drive of the tamping unit according to FIG. 1

- Each stuffing pike 3 is attached to a pimple 4.
- the respective picking arm 4 is pivotally connected to a lowerable stuffing tool carrier 5 and connected to a piston rod of an associated auxiliary cylinder 6.
- Also attached to the stuffing tool carrier 5 is the vibratory drive 2, to which each picking arm 4 is connected via the associated auxiliary cylinder 6. A generated vibration is thus transmitted via the respective auxiliary cylinder 6 to the respective picking arm 4 and the tamping pick 3 attached thereto.
- the vibration drive comprises a shaft 7 which is mounted in a housing 8 with sealed passages. At least one further sealed passage is provided for a transmission element 9, on which the auxiliary cylinder 6 of the tamping unit. 1

- Transmission element 9 The oil-lubricated roller bearing 19 between transmission element 9 and eccentric 12 shown in FIG. 2 is not shown in FIGS. 3-6 for the sake of clarity.
- the adjusting device 14 conveniently comprises a hydraulic
- Cylinder 20 which is arranged in the shaft 7 and presses a piston 21 against an inner surface of the seated on the shaft 7 eccentric 12.
- a mechanical adjusting device instead of a hydraulic adjusting device 14, a mechanical adjusting device, not shown, can be used. This includes, for example, in the shaft 7 guided spindles or crankshafts to adjust the position of the eccentric 12 relative to the shaft 7.

- each value between zero and a maximum value can be set for the axial spacing 15. This results in a constant torque a reduced center distance 15 not only to a lower vibration amplitude, but also to a higher impact force of the vibratory drive 2. This is advantageous for the operation of Stopfaggregats 1 to adjust, if necessary, the effect of the respective vibrating stuffing 3 on a ballast bed ,
- the free ends of the pistons 21, 22 are inserted in a respective longitudinal groove on an inner surface of the eccentric 12 and by means of fastening means 24 in
- the pistons 21, 22 serve on the one hand the adjustment in the radial direction and on the other hand as elements of a rotationally-locked connection between the shaft 7 and the eccentric 12.

- the vibration frequency is set to 35 Hertz in this phase.
- Vibrational movements therefore continuously lead to release and absorption of kinetic energy. Much of this fluctuating
- the shaft 7 is additionally coupled to a flywheel to keep constant the angular velocity of the rotating masses independently of a rotational drive over a period of oscillation.
- the power consumption of the vibration drive 2 according to the invention is thus significantly lower than that of a linear vibration drive, which generates a vibration, for example by means of a hydraulic cylinder.
- the vibration amplitude is reduced to zero, during which the vibration frequency remains constant. Without the eccentric adjustment according to the invention, the shaft 7 would have to be braked in order to suspend the vibration. The vibration drive 2 would inevitably go through low frequency ranges. Components of a tamping unit 1 comprehensive stuffing machine or elements of

- axial spacing 15 For a particularly precise adjustment of the axial spacing 15 can be realized.
- the shaft 7 is driven by means of a hydraulic motor, which in the
- Tamping machine uses existing hydraulic system. Thus, a sufficiently high torque is available and the speed is infinitely adjustable.
