    description
    The invention relates to a track construction machine with a movable on a track machine frame, various work units and with an internal combustion engine which is connectable via a clutch with a transfer case, said at this hydraulic pumps to supply diverse hydraulic drives of a hydraulic system are connected. The invention also relates to a method for the operation of a power supply system for driving various work units and drives a - on a track having an electrical overhead line track - track construction machine.
    Since track laying machines are often used on non-electrified tracks, the energy supply is usually carried out exclusively by an internal combustion engine.
    The object of the present invention is now to provide a track-laying machine and a method of the type mentioned, with or a more versatile site application is possible.
    This object is achieved according to the invention by the features cited in the characterizing part of claims 1 and 5, respectively.
    These feature combinations make it possible to use a more environmentally friendly energy supply in the case of an existing track overhead without affecting the performance of the track construction machine. This possibility of a purely electric drive is particularly advantageous when working in tunnels. In addition, the electric drive can significantly reduce noise emissions and energy consumption. By changing the power supply during load operation, no interruption of the working approach is required, thus ensuring a consistent quality of work.
    Specifically, switching between the electric motor and the internal combustion engine takes place without interrupting the drive of the transfer case, so that the various hydraulic drives and working units continue to run smoothly. This is particularly advantageous for continuously operating track construction machines such as tamping machines, cleaning machines, leveling machines or machines for stabilizing and compacting the track bedding as well as for ballast removal and ballast distribution. With this type of machinery, it is also assumed that a catenary remains switched on during a working process. The situation is different with construction work on the overhead line.
    Further advantages of the invention will become apparent from the dependent claims and the drawing description.
    Thus, advantageously, the internal combustion engine and the electric motor are controlled by means of a control device, which is set up to coordinate operating parameters between the two motors. This is done in a simple manner, a continuous power takeover by the switched-motor by the speed and the torque of the wegzuschaltenden engine are taken.
    Furthermore, it is advantageous if the electric motor for alternative power supply of the intermediate circuit in a regenerative operation by the internal combustion engine is driven. This can be useful on the one hand with an excess of energy during a braking phase. On the other hand, this also creates a further possibility for the permanent supply of the intermediate circuit with a disconnected current collector. The inventively provided generator or the electrical energy storage must then be designed only for a charge of the intermediate circuit at the beginning of a pure engine operation. A powered via the intermediate circuit vehicle electrical system of the track construction machine is maintained in this way by means of the electric motor in the generator mode.
    It is also advantageous if a voltage limiter is connected to the DC link. This is suitable, for example, for converting excess braking energy, which can not be fed into the overhead line, into heat.
    In the following the invention will be described with reference to an embodiment shown in the drawings. 1 shows a simplified side view of a track construction machine, and FIG. 2 shows a schematic representation of a power supply system.
    A track construction machine 1 shown in FIG. 1, for example as a tamping machine, with a machine frame 3 that can be moved on a track 2 is equipped with various working units 4 as well as an internal combustion engine 5. As can be seen in Fig. 2, this is connectable via a coupling 6 with a transfer case 7. At this hydraulic pumps 8 are flanged to supply various hydraulic actuators 9. These form together with the hydraulic pumps 8, a hydraulic system 10. For an extension of a formed by the engine 5 and the hydraulic system 10 power supply system 11 is coupled to an electric DC link 12 electric motor 13 is provided. This can be replaced as an alternative drive for the transfer case 7 and coupled to the power supply with a height-adjustable, can be applied to a catenary 14 of the track 2 pantograph 15. The electric motor 13 is flanged by a slip clutch 19 to the transfer case 7. For alternative energy supply of the intermediate circuit 12, a generator 16 or alternatively an electric energy storage 21 shown here with dashed lines is provided. The generator 16 is hydraulically drivable via the transfer case 7 or coupled to an auxiliary combustion engine. The electrical energy storage 21 can optionally be charged by means of the electric motor in the generator mode or via the overhead line 14 with energy. For the labor input, the hydraulic system 10 can alternatively be powered by the engine 5 or in the case of an existing overhead line 14 by the powered by the overhead line 14 electric motor 13 with energy. The switching between the combustion and electric motor 5 and 13 is advantageously carried out in a the drives 9 and 4 power units permanently supplied with energy load operation. Thus, no disadvantageous interruption of the work precedence is required. Conveniently, the electric motor 13 is formed as an asynchronous machine, which is connected via a converter to the intermediate circuit 12. A bidirectional inverter allows a regenerative operation of the electric motor 13. When activating this operating mode, an exciter voltage must be applied to the asynchronous machine. If this is derived from the intermediate circuit voltage, the intermediate circuit 12 must first be charged. This is done with available overhead line 14 by means of the current collector 15, which is coupled via a main switch 18 and a transformer, not shown, with the intermediate circuit 12. In pure combustion engine operation, the intermediate circuit 12 is precharged by means of the generator 16 or the electrical energy store 21. For a successful under unrestricted load operation of the track construction machine 1 changing the power supply from the electric to the engine 13 and 5, the latter is raised at a disengaged from the transfer case 7 clutch 6 to a required speed for the load operation. This conversion of the power supply is advantageously carried out automatically by operating a corresponding switch. As a next step, with a closing of the clutch 6 by a control device 17, a coordination of all - required for the power supply and the engine operation - operating parameters on the engine 5 is performed automatically (transmission of the sovereignty).
    A speed control of the electric motor 13 is inactive and the internal combustion engine 5 drives the transfer case 7 with the currently required power. To ensure this uninterrupted change, both motors are driven by the same control device 17 5. 17. Finally, the power supply from the overhead line 14 to the electric motor 13 is interrupted by the main switch 18. This is conveniently done automatically by driving the main switch 18 by means of the control device 17. For taking place under unrestricted load operation of the track-laying machine 1 change of energy supply from the combustion to the electric motor 5 and 13 of the main switch 18 for electrically coupling the electric motor 13 with the at Catenary 14 applied pantograph 15 operated. Thereupon, by means of the control device 17 automatically a vote of all - required for the power supply and the engine operation - operating parameters on the electric motor 13 (transfer of control sovereignty).
    Concretely, when the intermediate circuit 12 is preloaded, the speed control of the electric motor 13 is activated, wherein a predetermined speed and a torque of the electric motor 13 are tuned to a power of the internal combustion engine 5 to be switched off. Subsequently, the internal combustion engine 5 is separated by actuation of the associated clutch 6 from the transfer case 7.
    The entire change is conveniently carried out automatically by means of the control device 17. Thus, the control device 17 forms a central element that drives both motors 5, 13 and the main switch 18. To trigger a changeover between the two motors 5, 13, the control device 17 is connected to an operating unit. A triggering can also be done automatically, for example, after a predetermined period of time.
    As is known, adjacent sectors of the overhead line 14 are separated from one another by so-called transfer points 20 (indicated schematically in FIG. 1). For higher vehicle speeds, it is no problem due to the existing kinetic energy to briefly interrupt the electric drive in order to drive over the transfer point 20 without drive. For overriding of Überleitstellen 20 of the overhead line 14 under load operation of the track construction machine 1 is automatically activated after activation of the control device 17 before the transfer point 20, a change of power from the electric to the engine 13, 5 and after an adjustable time or a predetermined distance traveled Change of power supply from the combustion to the electric motor 5, 13 carried out. It may also be advantageous if the control device 17 is reported by means of sensors, that the passing of a transfer point 20 is completed. Such a message then automatically triggers a change back to the electric motor 13.
