    专利说明:

    [01] The invention relates to a tamping unit according to the features cited in the preamble of claim 1 and to a method for submerging a track, the known features of which are cited in the preamble of claim 5.
    [02] A tamping unit is known from EP 1 653 003 A1, in which tamping knives are moved in pairs relative to one another in order to plug a track together. This additional movement for ballast compaction is carried out with the aid of a hydraulically actuated auxiliary cylinder. The addition movement is hydraulically superimposed on a vibratory movement in order to achieve easier penetration into the ballast and improved compaction.
    [03] The object of the present invention is now to provide a tamping unit and a method of the type mentioned, with a reduced energy consumption for the vibration superposition in the Beistellantrieben is possible.
    This object is achieved with a Stopfaggregat or a method of the generic type by the features cited in the characterizing part of the main claims 1 and 5, respectively.
    [05] With such a third pressure chamber, an advantageous separation between the pressurization for the Beistellbewegung and this superimposed vibration amplitude can be achieved. As a result of the addition of auxiliary and vibrational pulses, lower pressures can be used while reducing the energy expenditure. In the case of encrusted gravel can be achieved with a pressure increase significantly higher impact in the direction of Beistellbewegung while maintaining the vibration amplitude.
    [06] Further advantages of the invention will become apparent from the claims and the description of the drawings.
    [07] In the following the invention will be described in more detail with reference to an embodiment shown in the drawing. 1 shows a side view of a tamping machine with a tamping unit, FIG. 2 shows an enlarged side view of the tamping unit having auxiliary drives, and FIG. 3 shows a schematic cross section through a side drive.
    A tamping machine 1, shown in simplified form in FIG. 1, has a machine frame 4 which can be moved by rail carriages 2 on a track 3. Between the two rail bogies 2 a height adjustable by a drive 5 Stopfaggregat 6 for Unterstopfen thresholds 7 is arranged.
    The tamping unit 6 shown enlarged in Fig. 2 has in a Beistellbewegung 8 in pairs about a pivot axis 9 to each other movable, at a lower end 10 with stuffing tugs 11 connected tamping 12 on. These are connected at an upper end 13 each with a hydraulic Beistellantrieb 14, which are formed both for carrying out the Beistellbewegung 8 and one of these superimposed vibration. Both stuffing lever 12 and the Beistellantriebe 14 are mounted on a height adjustable by the drive 5 relative to an aggregate frame 15 carrier 16.
    As shown in Fig. 3, in a - a Beistellkolben 17 with a piston rod 18 having - hydraulic cylinder 19 of the Beistellantriebes 14, a first pressure chamber 20 for generating the Beistellbewegung 8 is arranged. For one of the Beistellbewegung 8 opposing opening movement piston rod side, a second pressure chamber 21 is provided.
    [11] A third pressure chamber 22 provided for generating vibration is formed by a cavity 23 arranged in the piston rod 18. This is limited piston side by a fixed to a cylinder bottom 24 of the hydraulic cylinder 19 second piston rod 25. Both piston rods 18, 25 are arranged coaxially to a cylinder axis 26 of the hydraulic cylinder 19.
    The three pressure chambers 20, 21, 22 are each associated with hydraulic lines 27, wherein the connected to the first pressure chamber 20 hydraulic line 27 is connected to a formed as a bladder accumulator energy storage 28. A piston surface 29 of the second piston rod 25 and a piston rod-side piston surface 30 of the Beistellkolbens 17 have the same area.
    To clog the threshold 7, each of the first pressure chamber 20 each Beistellantriebes 14 both stuffing lever 12 are pivoted to each other about a pivoting axis 9 to each other by applying the first two pressure chambers 20, whereby the tamping 11 are provided in the Beistellbewegung 8 to each other. After completion of the Beistellbewegung or the ballast compaction, the opposing opening movement is achieved by applying the second pressure chamber 21.
    [14] The supply and opening movement of the tamping pickles 11 is superimposed on a preferably sinusoidal oscillation composed of two oscillation amplitudes, the first oscillation amplitude acting in the direction of the auxiliary movement 8 (see FIG. 3) being generated by a pressure pulse in the third pressure chamber 22 becomes. This adds additional and vibrational force in the very important Beistellbewegung for gravel compaction or for the breaking up of crusted gravel.
    [15] The second oscillation amplitude effective in the opposite direction (in the opening direction of the stuffing tongs 11) is formed by a pressure pulse in the second pressure chamber 21.
    [16] The second vibration pulse causes fluid displacement from the first pressure chamber 20. The energy generated in this way is in
    Energy storage 28 buffered and returned to the activation of the first vibration pulse back into the first pressure chamber 20.
