    The invention relates to a method and a Stopfaggregat for undercutting a track according to the cited in the preamble of claims 1 and 5 features.
    Such 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 linear addition movement is hydraulically superimposed with a vibration to allow easier penetration into the ballast and improved compaction.
    The object of the present invention is to provide a method and a tamping unit of the type mentioned, with which an improvement of the hydraulic vibration generation is possible.
    This object is achieved with a method or tamping unit of the generic type by the cited in the characterizing part of claims 1 and 5 features.
    With the combination of features according to the invention, an optimization of the parameters required for vibration generation is possible independent of the additional movement of the tamping picks. An improvement, in particular with regard to the energy balance, can be achieved if the vibration piston is effective as a spring-mass system. With such an energy storage of the high hydraulic energy consumption required per se for the generation of vibrations is significantly reduced. Another resulting advantage can be seen in a lower noise emission.
    Further advantages of the invention will become apparent from the dependent claims and the drawing description.
    In the following the invention will be described with reference to an embodiment shown in the drawing. 1 is a simplified side view of a tamping machine with a Stopfaggregat for undercutting a track, Fig. 2 is an enlarged view of a Beistellantriebe tamping unit, and Fig. 3 to 6 each show a variant of an inventive Beistellantriebes.
    A tamping machine 1 which can be seen in FIG. 1 has a machine frame 4 that 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 Stopfaggregat 6 shown enlarged in Fig. 2 has in a Beistellbewegung 8 in pairs about a pivot axis 9 to each other movable, connected at a lower end 10 with stuffing pickles 11
    Tamping 12 on. These are connected at an upper end 13 each with a hydraulic Beistellantrieb 14, which are designed both for carrying out the linear 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.
    The auxiliary drives 14 shown in detail in FIGS. 3 to 6 each have a lateral piston 19 that can be moved along an axis 17 of a side-by-side cylinder 18 and a side piston rod 20 connected thereto. In the illustrated version, these are hydraulically moved from left to right in order to execute the linear auxiliary movement movement 8 (see in this regard the hydraulic lines 21 with a valve 22 or a pressure limiting valve 23.
    In each auxiliary drive 14 or auxiliary cylinder 18, a vibration piston 24 designed to generate the vibrations is arranged in addition to the auxiliary piston 19 provided for the auxiliary movement 8. This is arranged in the two variants according to FIGS. 3 and 4 in each case between the side piston 19 and a cylinder bottom 25 of the auxiliary drive 14.
    As can be seen in Fig. 3, a connected to the vibrating piston 24 piston rod 26 is mounted in a cylinder bottom 27 fixed to the cylinder ring 27 for displacement along the axis 17 of the auxiliary cylinder 18 is. In cavities 28 of the cylinder ring 27, the vibrating piston 24 contacting energy storage 29, preferably mechanical springs 30, arranged for the exercise of parallel to the axis 17 effective forces.
    A formed by the cylinder bottom 25, the cylinder ring 27 and the piston rod 26 of the vibrating piston 24 oil chamber 31 is acted upon by a hydraulic line 32 for generating a first oscillating motion 33 with high pressure. On the vibrating piston 24 and / or on the Beistellkolben 19 an end position damping 34 is arranged.
    The Beistellkolben 19 is offset together with the Beistellkolbenstange 20 by corresponding position of the valve 22 and actuation of a Beistell- and vibration piston 19, 24 limited oil chamber 44 in motion, which leads to each other in pairs opposite tamping 11 in the context of Beistellbewegung 8 (s.
    Fig. 1). The constant amplitude oscillation superimposed on this linear addition movement is generated by the vibration piston 24 which can be moved independently of the supply piston 19. The cushioning 34 prevents vibrating and Beistellkolben 24, 19 have abrupt contact.
    Through the hydraulic line 32, the volume flow for the vibration or the first oscillating movement of the oil chamber 31 is supplied. By a fast switching valve 35 while the vibration is generated. This
    Valve 35 can pulse-through the high-pressure side, whereby the vibrating piston 24 is shifted to the right and the mechanical spring 30 is tensioned.
    When the valve 35 is reset, a connection to a storage container is established. In this position, a floating position is possible.
    As a result, the spring 30 can now reset the vibrating piston 24 (with a movement in the direction of the cylinder bottom 25) and the hydraulic oil is discharged into the storage container. The task of the energy store 29 is thus taken over by the mechanical spring 30 (alternatively, the energy store 29 can also be formed by a bubble store or the like). The vibration piston 24 and the springs 30 thus form a power conservation system 36 in the form of a spring-mass system. Ideally, the system 36 is operated near the resonant frequency of the spring - mass oscillator. With the pressure relief valve 23 a Beistelldruck for the Beistellbewegung and thus a dynamic counter cushion is constructed.
    The advantage of the solution described here over the known fully hydraulic Beistellantrieben is that the vibration movement is independent of the movement of the Beistellkolbens 19 feasible. It is well known that in the known hydraulic drive by the superposition of Beistell- and vibration movement, the flow rate is so high that the size of the valve unnecessarily increases and the entire volume flow of the superimposed vibration is converted into heat. This leads to a high energy consumption.
    It is further known or proven by measurements that with strong crusting of the gravel to be stuffed, the oscillation amplitude in a known fully hydraulic system can not be maintained (avoiding this disadvantage is possible only by an increased size). The reason is that no energy can be stored in the system at short notice.
    In contrast to the disadvantages shown in the known embodiments is in the drive concept according to the invention by the spring-mass system (formed by the springs 30 and the vibrating piston 24) an energy storage available. This energy corresponds to the function of a known from the prior art rotating flywheel with an eccentric drive for generating a stuffing pitch vibration. In addition, advantageously, the auxiliary movement can be carried out independently of the vibration amplitude of the vibration. This results in a simplified design of the valve for the auxiliary cylinder 18.
    In the embodiment according to FIG. 4, the vibrating piston 24 is connected by the mechanical springs 30 to a piston surface 37 of the auxiliary piston 19. The springs 30 could also be omitted. However, this would require a higher hydraulic pressure to produce the vibration and thereby degrade the efficiency.
    The Beistellkolben 19 and the Beistellkolbenstange associated with this 20 has a preferably coaxial to the axis 17 extending bore 38 for carrying out a first oscillatory movement 33 of the vibrating piston 24 generating vibration pulse (see also Fig. 5, 6). The vibration is generated by the valve 35, wherein the two pistons 19, 24 are moved apart. The Beistellbewegung the Beistellkolbens 19 is activated by the valve 22 and in an oil chamber 45 (limited by the vibrating piston 24 and the cylinder bottom 25) executed. The second (the first opposite) swinging motion is in turn activated by the energy conservation system 36 composed of vibrating piston 24 and springs 30.
    In the embodiments according to FIGS. 5 and 6, the vibrating piston 24 is designed in each case as an opening 40 for carrying the auxiliary piston rod 20 having ring 41. The mechanical springs 30 connected to the vibrating piston 24 are attached to a piston rod side piston surface 42 of the side piston 19 (see Fig. 5) or to a piston rod side cylinder bottom 43 of the auxiliary drive 14 (see Fig. 6). The vibration is generated as well as in the embodiment of FIG. 4 in a limited by vibrating and Beistellkolben 24,19, the springs 30 containing oil chamber 44th
    The control or regulation of the present invention is carried out by simple and robust sensors and the necessary variables for the control or control are determined by means of model predictive system (observer). From known, easily measured physical quantities or manipulated variables, the unmeasured magnitudes of an observed reference system are determined.
