    Description: [0001] The invention relates to a drive device for driving at least one rail wheel of a two-way vehicle according to the preamble of claim 1.
    If tools that can be driven with tires and / or caterpillars on terrain and roads are also to be used on rails, then these are designed as two-way vehicles with additional rail wheels. The rail wheels can be positioned in such a way that driving on tracks is made possible. In two-way vehicles with tires, solutions are known in which a frictional drive connection is formed from the tires to the tracks or to the rail wheels. An example of this is described in US 2013/0 087 067 A1. If a frictional drive connection is undesirable or is not possible, for example, in the case of caterpillars, the rail wheels are driven by drive devices assigned to the rail wheels or their axes.
    EP 2 847 011 B1 describes a two-way vehicle with four hydraulic motors, in each of which the shaft of a hydraulic motor is connected to the center of a rail wheel. The two hydraulic motors of the rail wheels of the two-way vehicle running on the same rail are connected in parallel to a common hydraulic pump and two separate hydraulic pumps are used for the two sides.
    When working on tracks, one-sided weight distributions or workers can achieve very large forces with a single rail wheel, which in the solution according to EP 2 847 011 B1 necessitates the use of undesirably massive hydraulic motors. In addition, strong vibrations can occur between the rail wheels and the tracks, which in the solution according to EP 2 847 011 B1 can lead to leaks in the hydraulic motors. Another disadvantage of the solution according to EP 2 847 011 B1 is that it cannot be used on narrow-gauge tracks. In the case of narrow-gauge tracks, sharp camber changes can occur over short distances in the case of narrow curves, which would lead to a rail wheel being lifted off and thus to the risk of derailment in a solution according to EP 2 847 011 B1.
    The object of the invention is now to find a drive device for driving at least one rail wheel of a two-way vehicle, which overcomes at least one disadvantage of the known designs. According to a further object for a preferred solution, the drive device for tracks with different track widths should be usable.
    The object is solved by the features of claim 1. The dependent claims describe alternative or advantageous design variants which solve further tasks, for example the usability with different track widths.
    The drive device according to the invention for driving at least one rail wheel of a two-way vehicle comprises at least one hydraulic motor with a housing and with a drive shaft extending along a drive axis. For the at least one hydraulic motor, the drive device comprises a connecting device arranged thereon, which is designed such that a rail wheel can be fastened thereon. For each hydraulic motor, the drive device comprises a support sleeve connected to the housing of the hydraulic motor, which extends around the drive axis, and at least one rotary bearing radially on the outside of the support sleeve. The drive shaft and the connecting device together form a connection leading through the support sleeve to the free end of the support sleeve. The connecting device extends outside the support sleeve to at least one pivot bearing.
    If large forces arise in a rail wheel arranged on the connecting device, these pass from the rail wheel via the at least one rotary bearing arranged on the support sleeve directly onto the support sleeve. The load on the rotary bearing between the drive shaft and the housing of the hydraulic motor can be minimized, so that no particularly massive hydraulic motor is necessary. Vibrations arising between the rail wheels and the tracks are also absorbed directly by the at least one rotary bearing arranged on the support sleeve and then by the support sleeve. A robust attachment of the support sleeve is associated with significantly less effort than a solid design of the bearing of the drive shaft of a hydraulic motor.
    In the inventive design, at least one pivot bearing can be arranged in a position along the drive axis at the rail wheel, so that the forces transmitted from the two-way vehicle via the pivot bearing and the rail wheel to the rail generate no leverage in the drive device. Accordingly, lever forces between the drive shaft and the housing are also eliminated in the hydraulic motor. This means that there is no need to build a massive hydraulic motor and the risk of leakage is very low.
    In a preferred embodiment, the support sleeve is connected to the housing of the hydraulic motor with a flange plate aligned perpendicular to the drive axis. The flange plate enables a robust attachment to a connection device with at least one attachment device to a working device with little effort.
    It is also advantageous if the connecting device adjoining the drive shaft has a central shaft section, at the free end of the support sleeve a cover disk oriented perpendicularly to the drive axis and a radially outer end of the cover disk fastened at least over part of the support sleeve against the drive motor extending against the hydraulic motor comprises, wherein the drive sleeve is rotatably mounted on the at least one pivot bearing on the support sleeve. The arrangement of the rotatable drive sleeve radially outside the support sleeve allows with klei
    CH 714 563 A2 a precise assembly of a rail wheel. With a drive sleeve that extends over a sufficiently large section of the drive axis in the respective rail of a track, precise positioning of the rail wheel on the respective drive sleeve of a universal drive device can be ensured for different track widths. So that rail wheels are optimally supported at different longitudinal positions of the drive sleeve, a pivot bearing is used between the support sleeve and drive sleeve at both end areas, or at the innermost and outermost position for a rail wheel arranged on the drive sleeve.
    Because the drive sleeve is rotatably mounted on the pivot sleeve on the support sleeve and fixed in the direction of the drive axis, a rail wheel attached to the drive sleeve also rotates at the position assigned to the rail when the cover plate is detached from the drive sleeve, or when the connection between the drive shaft and the drive sleeve is interrupted. This enables the two-way vehicle to move or be pulled on the track, even if the associated hydraulic drive is defective or blocked.
    The assembly of the central shaft section and the cover plate is particularly simple when the central shaft section engages with the drive shaft via a plug connection. In order to transmit the rotary movement from the drive shaft to the central shaft section, the cross section of the plug connection deviates from the circular shape and achieves the desired power transmission with a positive fit.
    Particularly advantageous is an embodiment in which the drive sleeve extends in the direction of the drive axis over a length which corresponds to at least half the difference between the rail distances of a normal and a narrow-gauge track and the thickness of a rail wheel. The drive sleeve includes devices for positioning a rail wheel at both end regions. With this embodiment, the same two-way vehicle can be used on tracks of both track widths. The conversion effort is limited to moving the rail wheels from one position to the other on the drive sleeve. If a pivot bearing is arranged inside the drive sleeve in both positions for a rail wheel, the bearing is also optimal for both track widths.
    Each device for positioning preferably comprises at least one bore, possibly at least a portion of an annular groove, and an annular element in the drive sleeve, the annular element being able to be positioned on the at least one bore or on at least a portion of the annular groove by means of screws engaging therein. The ring element can be clamped or released in the circumferential direction by clamping and / or releasing elements on the drive sleeve. A rail wheel is attached to the clamped ring element and is then in the desired position due to the positioning of the ring element.
    For construction, maintenance and repairs of all elements of tracks and lines, roads or all-terrain equipment such as excavators, transport and assembly vehicles can be used if they are equipped with rail wheels for two-way vehicles. For this purpose, particularly advantageous drive devices include a connection device for the supporting structure of the working devices.
    The connection device comprises at least one fastening device for the implement, at least one assembly device for the at least one hydraulic motor and at least one height adjustment. The at least one height adjustment is arranged between the at least one fastening device and the at least one assembly device and serves to lower the rail wheels onto the rails of a track and then to lift the wheels or caterpillars of the two-way vehicle out of the space required for driving on the rails.
    In an advantageous embodiment of the drive device, the height adjustment comprises two swivel joints on the fastening device, a swivel joint on the mounting device, a bracket of the mounting device connected to a swivel joint of the fastening device, and at least one hydraulic cylinder, which is on the one hand on a swivel joint of the fastening device and on the other hand on one Swivel joint of the mounting device is attached. It goes without saying that, if necessary, two swivel joints can be formed on the mounting device and one swivel joint on the fastening device, a carrier of the fastening device then being connected to a swivel joint of the mounting device. Optionally, the height adjustment between the fastening device and the mounting device instead of the described pivot arrangement comprises another guide device with linear or curved relative movement and a hydraulic or electromechanical actuation.
    In order to ensure the safe use of the two-way vehicle, even in the event of large increases in the height of a rail of the track over short distances, the connecting device comprises a self-aligning bearing which allows two mounting devices for hydraulic motors with a common drive axis to be oscillated about a pendulum axis oriented perpendicularly to this drive axis stored on the connection device. The pendulum bearing is particularly important if the two-way vehicle is to be used on narrow-gauge tracks.
    In an advantageous embodiment, the hydraulic motors for rail wheels, which run on the same rail of a track, are connected in series to the hydraulic circuit fed by a hydraulic pump. In this embodiment, the rail wheels run synchronously on the same rail and the throughput of the hydraulic fluid required for a desired rotational movement of both rail wheels can be kept low. The series-driven rail wheels also run synchronously when they are pressed onto the rail with different forces
    CH 714 563 A2. Due to the small throughput required to drive two rail wheels running on one rail, the hydraulic motors for all four wheels can be driven by a single hydraulic pump.
    The hydraulic motors enable both the drives and the braking of the rail wheels. When driving or braking, the hydraulic pump and / or a hydraulic control is set in such a way that the hydraulic circuit connected to it, through at least one hydraulic motor, achieves or at least attempts to achieve the desired speed of at least one rail wheel. Depending on the state of motion and the weight of the two-way vehicle and the slope of the track or rails, the desired speed or driving speed is reached after a time required for the speed change.
    When braking, it is important that the rail wheels if possible do not slip on the rails and that this standstill position can be maintained in the event of a standstill achieved on rails with a large incline. It has been shown that for safe and precisely controlled braking and maintaining the standstill position, the control of the hydraulic pump and the hydraulic control is not sufficient, because the risk of slipping is high and undesirable small movements occur during standstill. In a particularly advantageous embodiment, the drive device therefore also comprises a mechanical brake device, preferably with at least two brake shoes, and an actuating device, the brake shoes with the actuating device being able to be pressed against the outside of the drive sleeve of the drive device.
    If the two-way vehicle includes an implement with caterpillars and a rotating device between the caterpillars and the hydraulic drive for the caterpillars, it must be assumed that the rotary leadthrough only comprises bushings for hydraulic circuits for driving the caterpillars. When driving on the caterpillars, braking and holding the standstill position can be sufficiently ensured thanks to the large frictional forces between the ground and the caterpillars using the hydraulic control. However, if the implement with caterpillars has to be braked on rails by means of drive devices and held in the standstill position, the substantially lower friction between the rails and the rail wheels leads to undesirable faults.
    A particularly advantageous embodiment uses at least one hydraulic circuit to actuate the mechanical braking device. The hydraulic control is designed in such a way that mechanical braking can be achieved when performing hydraulic braking. So that the mechanical braking can also be ensured in the standstill position, the mechanical braking device is preferably brought into the braking position by a pretensioning device and is moved via the hydraulic control when driving the hydraulic motor to achieve a travel movement of the rail wheel against the action of the pretensioning device against the release position.
    If each rail wheel can be arranged on a drive sleeve in two different positions (normal gauge, narrow gauge), it is not expedient to brake mechanically on the rail wheels, because then the mechanical brake would have to be usable in two different positions. In a particularly advantageous embodiment, the drive sleeve, in particular the area of the drive sleeve between the two rail wheel positions, is used for the arrangement of brake shoes. At least two brake shoes are arranged so that they can be pressed against the drive sleeve at points opposite one another. The press jaws are preferably attached to lever arms and the lever arms are in particular pivotally arranged on a brake holder connected to the mounting device.
    In a preferred embodiment, the brake holder is released from the mounting device and moved away from the drive sleeve, at least to the extent that the brake shoes are no longer in the area around the rail wheel, for adjusting a rail wheel from the normal-track position to the narrow-track position. After moving the rail wheel, the brake bracket is connected to the mounting device again.
    For pressing and releasing the brake shoes, an actuator is preferably connected to the lever arms. The actuating device comprises, for example, a cylinder connected to one lever arm and a piston device connected to the other lever arm and displaceable in the cylinder. The biasing device comprises, for example, a spring which moves the cylinder and the piston device into a relative position in which the brake shoes press against the drive sleeve. When the hydraulic control drives the hydraulic motor to achieve a travel movement of the rail wheel, the hydraulic control supplies hydraulic fluid to the cylinder under such a pressure that the piston device, contrary to the action of the pretensioning device, actuates the two lever arms such that the brake shoes reduce the braking force acting on the drive sleeve or that the brake shoes allow the drive sleeve to rotate freely.

    1 and 2 show a drive device 1 with a connection device 2 for the supporting structure of an implement, not shown. The connection device 2 comprises at least one fastening device 3 for the working device, at least one mounting device 4 for a drive with at least one drive sleeve 5 and at least one height adjustment 6. The at least one height adjustment 6 is arranged and used between the at least one fastening device 3 and the at least one mounting device 4 To do this, lower the assembly device 4 against the rails of a track and then lift the wheels or caterpillars of the two-way vehicle out of the space required for driving on the tracks.
    The connection devices 2 shown in FIGS. 1 and 2 are designed to provide a first and a second axis for driving on tracks. In the embodiment shown, the two connection devices 2 are separated from one another and are thus each attached to the implement. It is also possible to form a connection device 2 with a common fastening device 3 and two mounting devices 4 thereon for the two axes. This corresponds to an embodiment in which the fastening devices 3 of FIGS. 1 and 2 are permanently connected to one another.
    The height adjustment shown comprises two two swivel joints 7 on the fastening device 3, two individual swivel joints 7 on the mounting device 4, two each with a swivel joint 7 of the fastening device 3 connected to the carrier 8 of the mounting device 4 and two hydraulic cylinders 9, on the one hand on a swivel joint 7 of the fastening device 3 and, on the other hand, are fastened to a swivel joint 7 of the mounting device 4.
    Fig. 3 shows the basic design of a drive device 1 for driving a rail wheel 10 of a two-way vehicle. A hydraulic motor 11 comprises a housing 12 and a drive shaft 14 extending along a drive axis 13. A support sleeve 15 is connected to the housing 12 of the hydraulic motor 11 and extends around the drive axis 13. Two rotary bearings 16 are arranged on the support sleeve 15 on the radial outside the drive sleeve 5 is rotatably mounted. The hydraulic motor 11 drives the drive sleeve 5 via the drive shaft 14 and a connecting device connected to the drive shaft 14 and the drive sleeve 5. In the embodiment shown, the connecting device comprises a central shaft section 17 adjacent to the drive shaft 14 and, directly outside the free end of the support sleeve 15, a cover disk 18 oriented perpendicular to the drive axis 13, to which the drive sleeve 5 is fastened radially on the outside.
    The support sleeve 15 is connected to the housing 12 of the hydraulic motor 11 with a flange plate 19 aligned perpendicular to the drive axis 13. The flange plate 19 enables a robust attachment to the mounting device 4 with little effort. In order to optimally transmit the large forces acting on the support sleeve 15 to the flange plate 19, the support sleeve 15 is formed in its end region at the flange plate 19 with an increased wall thickness.
    The drive sleeve 5 shown in Fig. 3 extends in the direction of the drive axis 13 over a length which corresponds to at least half the difference between the rail distances of a normal and a narrow-gauge track and the thickness of a rail wheel 10. The drive sleeve 5 comprises devices for positioning a rail wheel 10 at both end regions. With this embodiment, however, of course only one rail wheel 10 per drive sleeve 5, the same two-way vehicle can be used on tracks of both track widths. The conversion effort is limited to the displacement of the rail wheels 10 from one position to the other on the drive sleeve 5. If in both positions for a rail wheel 10 inside the drive sleeve 5 a rotary bearing 16 is arranged, the bearing for both track widths is also optimal.
    A ring element 20 shown in FIG. 4 is part of a device for positioning a rail wheel
    10. Four radial bores 21 for position screws are formed in the ring element 20 along the circumference. Accordingly, four bores are formed in both positions on the drive sleeve 5, into which position screws screwed into the ring element 20 engage in order to secure the desired positioning. The ring element 20 is severed at least at one point in the circumferential direction and there has a tangential bore for a clamping and / or
    CH 714 563 A2
    Dissolving elements. In the slightly expanded state of the ring element 20, this is brought into a position on the drive sleeve 5, which is secured with the position screws. In this secured position, the ring element 20 is clamped to the drive sleeve, so that it is fixed to the drive sleeve both in the circumferential direction and in the axial direction. The ring element 20 comprises fastening bores 23 formed parallel to its central axis. A rail wheel 10 can be fastened to the ring element 20 with fastening screws 24 inserted into the fastening bores 23.
    5 and 6 show parts of a connecting device 2, with rail wheels for normal gauge NS and once for narrow gauge SS being drawn. In order to be able to absorb large forces between the rail wheels 10 and the connecting device 2, the flange plates 19 are screwed onto the end faces of robustly constructed boxes 25. The housing 12 of the hydraulic motors 11, together with the hydraulic connections, are arranged in a protected manner inside the boxes 25.
    Fig. 2 shows a connection device 2, in which the mounting device 4 comprises a self-aligning bearing for the drive shaft 13. For this purpose, the box 25 with the drive sleeves 5 arranged thereon and their common drive axis 13 is pivotably mounted on the mounting device 4 about a pendulum axis 26 in a predetermined angular range. The carrier 8 of the mounting device 4 are connected to a bearing housing 27 and the box 25 is mounted in the bearing housing 27 via a pendulum pin 28. The pendulum axis 26 runs perpendicular to the drive axis 13 and, when driving on tracks, essentially parallel to the rails. The self-aligning bearing is only provided on one of two drive axles 13 and ensures in areas with excessive rail runs that all four rail wheels are always in contact with the rail. The pendulum bearing is particularly important if the two-way vehicle is to be used on narrow-gauge tracks.
    7 to 9 show a section of a drive device 1 with a mechanical brake device 30 with two brake shoes 31 and an actuating device 32, the brake shoes 31 with the actuating device 32 being able to be pressed from the opposite side from the outside onto the drive sleeve 5 of the drive device 1 ,
    The illustrated embodiment uses a hydraulic circuit for actuating the mechanical braking device 30. The hydraulic control is designed such that mechanical braking can be achieved when performing hydraulic braking. So that the mechanical braking can also be ensured in the standstill position, the mechanical braking device is brought into the braking position by a pretensioning device 33 and is moved via the hydraulic control when driving the hydraulic motor to achieve a travel movement of the rail wheel against the action of the pretensioning device 33 against the release position.
    The rail wheel 10 can, as shown in FIGS. 7 and 8, be arranged on the drive sleeve 5 in two different positions (normal gauge, narrow gauge). The area of the drive sleeve 5 between the two rail wheel positions is used for the arrangement of brake shoes 31. Two brake shoes 31 are arranged such that they can be pressed against the cylindrical outer surface of the drive sleeve 5 from opposite sides. The press jaws 31 are attached to lever arms 34 and the lever arms 34 are pivotally attached to a brake holder 36. The brake holder 36 is arranged via a connecting piece 35 on the flange plate 19 connected to the mounting device 4 or the box 25.
    To adjust a rail wheel 10 from the normal-track position to the narrow-track position, the actuating device 32 is set such that the brake shoes 31 are sufficiently far away from the drive sleeve 5. Then the brake holder 36 is released from the connecting piece 35 and moved with the brake shoes 31 away from the drive sleeve until the brake shoes are no longer in the handling area of the rail wheel 10. After the rail wheel 10 has been moved and fixed in the desired position, the brake holder 36 is fastened again to the connecting piece 35.
    For pressing and releasing the brake shoes 31, the actuating device 32 comprises a cylinder 37 connected to a lever arm 34 and a piston device 38 connected to the other lever arm 34 and displaceable in the cylinder 37. The prestressing device 33 comprises, for example, a spring which holds the cylinder 37 and the piston device 38 moves into a relative position in which the brake shoes 31 press against the drive sleeve 5. An adjusting screw 33a enables the pretension to be set precisely. When the hydraulic control drives the hydraulic motor to achieve a travel movement of the rail wheel 10, the hydraulic control supplies hydraulic fluid to the cylinder under such a pressure that the piston device 38, contrary to the action of the pretensioning device 33, actuates the two lever arms 34 so that the brake shoes 31 open them reduce the braking force acting on the drive sleeve 5 or that the brake shoes 31 allow the drive sleeve 5 to rotate freely.
