    Tamping unit for tamping sleepers on a track
    TECHNICAL FIELD The invention relates to a tamping unit for tamping sleepers on a track, comprising a tamping unit with opposing tamping tools mounted on a lowerable tool carrier, each of which is connected to an auxiliary drive for generating an auxiliary movement, an eccentric shaft having an eccentric shaft for Generation of a vibration movement is provided.
    PRIOR ART For maintenance of a track or after a track renewal there is usually a need to compact a ballast bed. In addition to hand tampers, tamping units are known for this purpose, which are arranged on track construction machines. While the track is being tamped, the track-laying machine moves along the track, with tamping pick attached to the tamping unit being lowered into threshold compartments and provided.
    [03] A tamping unit is exposed to extremely high loads. Particularly when plunging into the ballast bed and then compacting the ballast below a threshold, high load changes occur constantly, which put a heavy load on the vibration drive. Even between the tamping processes, the tamping unit can be considerably loaded by a vibration drive that is constantly in operation and the vibration transmitted to the tamping tools.
    [04] Darning units for tamping sleepers of a track are already widely known, such as. B. by AT 350 097 B. As a vibration exciter is a rotatable eccentric shaft on which the auxiliary drives are articulated to transmit the vibrations to the tamping pick.

    SUMMARY OF THE INVENTION [05] The object of the invention is to provide an improvement over the prior art for a tamping unit of the type mentioned at the outset
    Specify technology.
    [06] According to the invention, this object is achieved by a tamping unit according to claim 1. Dependent claims indicate advantageous embodiments of the invention.
    [07] The invention provides that each auxiliary drive is supported on a bracket which has an annular housing section which is mounted on an eccentric section of the eccentric shaft which is assigned to the auxiliary drive. In this way, the design of the tamping unit is particularly narrow and compact. The arrangement of the brackets means that the auxiliary drive and the eccentric shaft are arranged one below the other to save space.
    In a simple embodiment of the invention it is provided that the respective housing section is mounted on the assigned eccentric section by means of a roller bearing. Rolling bearings are maintenance-free for the entire service life. Due to low frictional moments and also low heating, there are no additional devices at normal speeds - such as Oil cooling - required.
    [09] However, it is advantageous if oil-air lubrication is provided for the rolling bearing of the respective housing section on the assigned eccentric section. Such continuous lubrication with very small amounts of oil optimizes the service life of the rolling bearing. Due to the low oil requirement, only a small oil container is sufficient to ensure a long, uninterrupted service life. Such an oil container can be arranged in the immediate vicinity of the eccentric drive.
    [10] The respective console is preferably P-shaped with a support section pointing downwards. This configuration of the respective console enables a structurally simple and space-saving solution for the arrangement of the auxiliary drives.
    / 15
    1715
    3/8 [11] In an advantageous improved construction, the respective add-on drive is supported at one end on the associated console and connected at another point to the housing section of the console. By further supporting the ordering drive with respect to the console, there is an improved load distribution or power transmission. The individual components can then be optimally dimensioned and are accordingly easy to carry out.
    It is advantageous if the respective add-on drive is connected at a further point to the housing section of the assigned console by means of a clamp-shaped connecting element. This provides a structurally simple and inexpensive way of securely anchoring the auxiliary drive on the console.
    In an advantageous development of the invention, it is provided that the two auxiliary drives are arranged next to one another below the eccentric drive with an opposite orientation. This arrangement makes the individual tamping modules of the tamping unit as compact and compact as possible.
    [14] The respective tamping tool is advantageously connected to the associated auxiliary drive by means of a cranked lever arm. With this simple constructive solution it is achieved that the opposing tamping tools have a common line of action, although the associated auxiliary drives are arranged laterally offset from one another.
    [15] Furthermore, it is advantageous if the respective auxiliary drive is designed as a hydraulic cylinder. The asynchronous, pressure-dependent provision of the tamping picks thus achieved ensures uniform compaction under all thresholds of a track to be tamped. In addition, large forces can be applied with a small construction volume using the hydraulic cylinders.
    A further advantageous embodiment of the invention provides that the tamping unit comprises several tamping units of identical construction for simultaneously tamping several sleepers. The narrow design is particularly advantageous here. Thanks to this flexible design and variable combination of tamping units, the tamping units are perfectly adapted to / 15

    Conditions in work and adapted to customer requirements.
    In addition, the modular design enables economical and efficient
    Production.
    BRIEF DESCRIPTION OF THE DRAWINGS [17] The invention is explained below by way of example with reference to the accompanying figures. In a schematic representation:

    DESCRIPTION OF THE EMBODIMENTS [18] FIG. 1 shows a simplified illustrated tamping unit 1 for tamping sleepers 2 of a track 3 with a tool carrier 5 that can be lowered by a drive 4 and pairs of two opposing tamping tools 6. Each tamping tool 6 is connected via a swivel arm 7 and an auxiliary drive 8 connected to an eccentric drive 9. The auxiliary drive 8 is supported in each case on a bracket 10 which has an annular housing section 11 which is mounted on a respective eccentric portion 12 of an eccentric shaft 13 of the eccentric drive 9 which is assigned to the auxiliary drive 8. The respective swivel arm 7 has an upper swivel axis 14 on which the auxiliary drive 8 is mounted. The respective swivel arm 7 is rotatably mounted on the tool carrier 5 about a lower swivel axis 15. Such a tamping unit 1 is provided for installation in a tamping unit 16 in a track tamping machine or a tamping satellite that can be moved on track 3.
    [19] A side view of the stuffing unit 1 is shown in FIG. 2, the latter also being in a lowered position. The eccentric drive 9 together with / 15
    1715
    5/8 the two brackets 10 is on an eccentric axis 17 within the
    Tool carrier 5 arranged. The eccentric shaft 13 is on both sides via a
    Storage 18 rotatably supported within the tool carrier 5. The respective swivel arm 7 is designed as a cranked lever arm so that the
    Darning tools 6 are aligned opposite each other despite the eccentric sections arranged side by side.
    [20] In general, it is only through the use of the consoles 10 that the tamping units 1 and thus the combined tamping units 16 can be made particularly narrow in their dimensions, since the auxiliary drives 8 are arranged directly under the eccentric shaft 13.
    3 shows two tamping units 1 combined into a tamping unit 16 and arranged in a unit frame 19. In this way it is possible to implement multi-sleeper units simply and flexibly by combining several tamping units 1 in a modular design. Each module unit has its own drive 4, which is supported on the unit frame 19, in order to be lowered individually into a ballast bed as required.
    4 shows a detailed view of the eccentric drive 9 together with the eccentric shaft and bearing 18 arranged on both sides. The eccentric shaft 13 has two eccentric sections 12, with two eccentrics acting in opposite directions. The console 10 is arranged on the respective eccentric section 12. The associated auxiliary drive 8 is fastened to the respective console by means of screw connections 20.
    5 shows a detailed side view of the eccentric drive 9 together with brackets 10 and auxiliary drives 8. The two brackets 10 together with the annular housing sections 11 have an offset 21 due to the eccentric acting in opposite directions. In addition, it makes sense to connect the auxiliary drive 8 to the console 10 by means of a further fastening, in addition to the screw connections 20, because of the very high loads in operation. This attachment is implemented here, for example, by means of a clamp-shaped connecting element 22.
    6 shows the eccentric drive 9 shown in section. In the circular housing section 11 of the brackets 10 is a roller bearing 23 on the / 15th
    1715
    6/8 each eccentric section 12 arranged. The housing section 11 has a screwed housing cover 24 on the outside. Oil-air lubrication is provided as the lubrication. A slight excess air pressure is generated in the closed housing section 11 and an oil drop is supplied via an oil bore 25 every 5-6 minutes. At one end of the eccentric shaft 13, an internal toothing 26 is provided for a non-positive connection with a drive motor. This can be either hydraulic or electrical.
    7 shows a section through the auxiliary drive 8 arranged on the console 10. This has a piston rod 27 in order to press the respective swivel arm 7 outwards. In this way, an additional movement is superimposed on the vibration generated by eccentric drive 9.
