    Arrangement on the implement axle
    Background of the Invention
    The invention relates to an arrangement in a machine tool shaft.
    The invention further relates to a bottom armor and to a method for improving the durability of a machine tool shaft.
    The subject matter of the invention is described in more detail in the preambles of the independent claims of the application.
    Heavy-duty machine chassis uses axle boxes to support wheels on the machine frame. Particularly in the 10 machines for off-road and rough terrain, it is typical to use shafts with rocking gear. The rocking shaft includes a transverse shaft, both ends of which are provided with rockers, which in turn comprise wheels. The transverse shaft body is modular15 and consists of a plurality of screw members secured to each other. The shaft is subjected to high forces during machine operation. Problems have been found with the durability of current transverse shafts. Breakage of the axle body parts will result in the interruption of machine production20 operation and repair costs. Further, breakage of the frame member can also cause breakage of other axial parts before the fault is detected.
    Brief Description of the Invention
    The idea of the invention is to provide a novel and improved arrangement and a bottom armor for a machine tool shaft and a method for improving the resistance of a transverse shaft included in the shaft.
    Characteristic features of the arrangement according to the invention are set forth in the characterizing part of the independent device claim.
    The features of the base armor of the invention are set forth in the characterizing part of another independent device claim.

    Characteristic features of the method according to the invention are set forth in the characterizing part of the independent method claim.
    The idea of the disclosed solution is that the axle set of the implement comprises a transverse transverse axis to the implement frame, and rocking rockers are mounted on both ends of the transverse axis. The shaft assembly is secured to the implement body by means of mounting surfaces and vertical mounting screws between the upper surface of the shaft tubes and the lower surface of the implement frame. Further, the central body of the transverse shaft and the shaft tubes are connected to each other by screw connections. The transverse shaft body is thus modular. Further, one or more clamping devices are arranged between said shaft tubes, which are arranged to pull the shaft tubes towards each other and towards the center frame. In other words, said clamping device compresses parts of the modular body 20 and prevents breakage of the flange connections between the modules.
    One of the advantages of the disclosed solution is that the clamping device receives the loads on the transverse shaft body, thereby increasing its stiffness and durability.
    The clamping device prevents tears from forming in the body modules, and in particular in the area of their mounting flanges. This can increase the lifetime of the transverse shaft and reduce the cost of breakages and consequent downtime and unnecessary downtime. Further, when the stiffness of the shaft 30 can be increased by means of clamping devices, it is then possible to even increase the width of the rings and the rollers mounted on them without compromising the cross-axis durability.
    A further advantage is that the rigid body structure of the boom shaft can also enable the implement
    20185481 prh 25 -05-2018 load increase. This can increase the capacity of the machine without compromising durability.
    The idea of the bottom armor shown is that the base structure of the base armor comprises a plate-like metal body having an upper surface and a lower surface. The bottom armor also has fastening means for securing it below the cross-member of the implement and support means for supporting its upper surface against the lower surface of the cross-member. Further, the bottom armor comprises, on its upper surface side, two clamping devices, each having an elongated body and coupling eyelets at both ends of said body. The distance between the coupling eyelets can be changed using the screw mechanism included in the clamping device. By connecting the clamping devices of the bottom armor to the shaft tubes 15 belonging to the transverse shaft, they can be pulled towards each other, so that a supporting force is maintained on the underside of the transverse shaft which holds the transverse shaft module together.
    The idea of one embodiment is that said clamping device is an external and separate component with respect to the cross-shaft structure, which can be fixed and detached without disassembling the cross-shaft structure. The clamping device can be attached to existing cross-shaft mounting points. There is no need to make any changes to the pendulum structure of the transverse axis pe25 and its modules when the clamping member is an external element. Further, such a separate clamping device can be retrofitted to the transverse shaft without disassembling it.
    The idea of one embodiment is that the installation of the clamping device does not require any changes in the construction of the shafts. In this case, the clamping device can be mounted on any axle according to the definition. Further, the clamping device can also be retrofitted to the existing axle strips. The flexible clamping device shown is easy and fast due to its flexible attachment capability
    20185481 prh 25 -05-2018 can be installed and can also be easily replaced in case of a possible breakdown.
    The idea of one embodiment is that said clamping device is disposed on the lower surface 5 of the transverse axis, i.e. on the side opposite to said fastening surfaces. Thus, the upper surface of the transverse shaft is supported on the frame beams of the implement and the lower surface supported by one or more clamping devices.
    The idea of one embodiment is that the arrangement comprises two clamping devices arranged on both sides of the central axis of the transverse axis. In this case, the clamping force is uniformly applied to the transverse shaft without causing a bending load. In addition, more clamping devices can more easily produce the necessary tension force than a single clamping device. On the other hand, when more than one clamping device is used, the size of a single clamping device may be smaller than one large device, making it easier to fit the clamping devices to the transverse axis without having to compromise the ground clearance below the transverse axis 20.
    The idea of one embodiment is that the clamping devices are arranged substantially higher than the lowest point of the curved lower surface of the transverse shaft, whereby the clamping devices do not reduce the ground clearance of the work machine at the off-axis.
    The idea of one embodiment is that the clamping device is an elongated body having both ends comprising coupling means for coupling to fastening screws between the shaft tubes and the implement frame and means 30 for moving the coupling members towards and away from each other in the longitudinal direction of the clamping device.
    The idea of one embodiment is that the clamping device comprises an elongated body having both ends provided with coupling loops and which body defines the distance between the coupling loops of the screw mechanism.
    20185481 prh 25 -05-2018 to change. The coupling eyelets make it easy and quick to connect the clamping device to the cross shaft mounting screws. The screw mechanism is a simple and durable member capable of exerting a large force on its size.
    The idea of one embodiment is that the clamping device comprises, instead of a screw mechanism, another mechanical actuator for generating the required force. Thus, the force element of the tensioning device may be based, for example, on the use of wedge elements. Further, in some cases, it may be possible to provide the necessary clamping force by means of a hydraulic actuator, such as a hydraulic cylinder.
    The idea of one embodiment is that there is at least one joint between each of the tensioning loops of the tensioning device and the tensioning body, which allows for mutual rotation between the tensioning loops and the body during installation of the tensioning device. The pivot mechanism speeds up installation. Further, the joints allow it to be possible to attach the same clamping device to different implements, even without modification.
    The idea of one embodiment is that on the underside of the transverse axis there is a bottom armor, which is a plate-like body. At least one clamping device is disposed between the upper surface of the base armor and the lower surface of the transverse axis. In this case, the bottom armor also protects the clamping device along the cross-axis structure li25.
    The idea of one embodiment is that the bottom armor is provided with two clamping devices. The clamping devices may be disposed on the upper surface of the plate-like base of the base armor to protect the base armor. Further, the clamping means may be arranged on either side of the transverse axis, whereby the upper surface of the bottom armor may be against the lower surface of the transverse shaft and the clamping devices will not reduce the ground clearance between the bottom armor and the ground.
    20185481 prh 25 -05- 2018
    The idea of one embodiment is that the bottom armor comprises at least one drive opening for the clamping device so that the screw mechanism of the clamping device is rotatable from the underside of the bottom armor and through said access opening. The shaft of a machine for off-road use typically has a large ground clearance so that there is plenty of space underneath the transverse shaft for mounting and adjusting the tensioner.
    The idea of one embodiment is that the bottom armor comprises a plurality of screw openings at the vertical fastening screws between the shaft tubes and the machine frame so that said vertical fastening screws are accessible through said screw openings. The bottom armor also provides underside protection for fastening screws 15.
    The idea of one embodiment is that the base armor is secured to the transverse shaft only by said one or more clamping devices. In this case, there is no need to provide 20 separate fastening means for attaching the bottom armor. Further, removal and fastening can be fast when the fastening is performed simultaneously with the clamping device.
    The idea of one embodiment is that the upper surface side of the bottom armor is provided with upwardly projecting projections adapted to rest against the underside of the transverse axis, thereby transmitting upward forces on the transverse axis to the transverse axis. Said projections may also act as fastening means for the clamping devices.
    The idea of one embodiment is that the bottom surface of the bottom armor is flat without projections, whereby it is adapted to act as a sliding surface below the transverse axis.
    The idea of one embodiment is that the ki35 crossover device comprises coupling members that are attached
    20185481 prh 25 -05-2018 at least the vertical mounting screws between the shaft tubes and the machine frame.
    The idea of one embodiment is that the coupling members of the clamping device are fastened in addition to the said vertical fastening screws, but also to the horizontal fastening screws, in which the shaft pipes are mounted transversely to the machine frame.
    The idea of one embodiment is that the arrangement comprises an adapter piece by means of which the clamping device 10 can be fastened simultaneously to both the vertical fastening screws and the horizontal fastening screws. This allows the clamping forces to be applied to a plurality of clamping screws, even in different directions, whereby high clamping forces can be applied. The adapter piece balances the loads between the fastening bolts, The adapter piece can be a cast or sheet-shaped simple piece with mounting holes for vertical and horizontal mounting screws and means for attaching the clamping device to the coupling eye. An alternative to using the adapter piece is that the tensioner coupling member is shaped so that it can be attached to both vertical and horizontal mounting screws.
    The idea of one embodiment is that the coupling members of the ki25 crossover device are only attached to the horizontal mounting screws.
    The idea of one embodiment is that the bottom armor is a rectangular piece having two opposed short sides and two opposed long si30 arms. The clamping devices are arranged parallel to the long sides and at a transverse distance from each other.
    The idea of one embodiment is that the clamping devices are secured to the upper surface of the base armor by a pivot mechanism such that the position of the coupling loops 35 with respect to the clamping device body is rotatable. The pivot mechanism facilitates the installation of the clamping device.
    20185481 prh 25 -05- 2018
    The idea of one embodiment is that the bottom armor is secured to the transverse shaft structure by means of coupling loops of the clamping devices, so that there is no need for any separate fastening means in the plate-like base part of the bottom armor. In this way, the coupling loops can be used simultaneously for two different purposes, and the basic structure of the base armor can be remarkably simple, which can also be durable and easy to manufacture.
    The idea of one embodiment is that the bottom armor is secured by separate vertical fastening screws to the transverse shaft structure or to the implement frame structure from the front and rear side of the transverse shaft. In this case, the attachment of the bottom armor may be based on both the fastening of the clamping means 15 and the separate fastening screws, or alternatively the fastening may be provided solely by separate vertical fastening screws. The plate-like structure of the bottom armor may have mounting holes for vertical mounting screws. The locations and dimensions of the locking openings can be designed on a case-by-case basis.
    The idea of an embodiment is that the implement is a forestry implement, such as a harvester or forwarder.
    The idea of one embodiment is that the work machine is an earth moving machine, such as a dumper, or mining truck, or a loading machine.
    The idea of an embodiment is that the implement is an off-road vehicle, such as a military vehicle.
    The idea of one embodiment is that the transverse axis body is modular, comprising said hollow shaft tubes removably attached to the central body and to its opposite sides.
    The idea of one embodiment is that the akse35 mold is a Draw structure with
    20185481 prh 25 -05-2018 transmission and shaft passes through the transmission shafts, which transmit the rotational motion transmitted to the differential to the rockers and further to the machine wheels. The middle frame may also be referred to as a differential part. Further, the middle body is known by the colloquial name banjo and the shaft tube by the name banjo tube, respectively.
    The idea of one embodiment is that a brake device is fitted inside each shaft tube of the axle assembly.
    The idea of one embodiment is that there is a flange connection between the shaft tube and the center frame, in which the shaft tube flange is tightened by means of axial screws against the mounting surface in the center frame.
    The idea of one embodiment is a method of attaching the modular cross-member body parts of the implement to each other and to the implement frame. In the method, the shaft tubes are fastened to both sides of the center axis of the transverse shaft using screw fixing. The assembled transverse arm is fixed to the implement frame by the vertical fixing screws and the horizontal fixing screws at the shaft tubes. In addition, one or more external clamping devices are provided on the underside of the transverse shaft, which is coupled to the fastening screws between the transverse shaft and the machine frame at the transverse shaft tubes. The clamping device pulls the transverse shaft shaft tubes towards each other. The clamping device is capable of absorbing forces which tend to spread the shaft tubes apart. When the tensioner receives a part of the loads on the transverse shaft, the durability of the modular transverse shaft body parts is improved.
    The idea of one embodiment is that the tensioning device coupling member has one or more 35 amp articulated loop members or the like.
    20185481 prh 25 -05- 2018
    The idea of one embodiment is that the arm of the coupling member is bent to an angle with respect to its body.
    The idea of one embodiment is to refinish the broken shaft tube of the housing and, by means of one or more clamping devices, to ensure that the repaired shaft tube is as good or better as the original shaft tube.
    The above embodiments and the features disclosed therein can be combined to provide the desired solutions.

    Detailed Description of Some Embodiments
    Figure 1 shows a working machine 1, in this case a driving machine, which is a forestry working machine for forestry use. The implement 1 comprises a base 2, which may comprise a front frame 3 and a rear frame 4 and a joint N between them for guiding the frame. In addition to the cab 5, a power unit unit 6 is mounted on the front frame 3 with its auxiliary equipment. On the other hand, a cargo space 7 with its banks 8 and a timber handling crane 9 are provided on the rear frame 4. In the working machine 1 shown in the figure, both the front frame 3 and the rear frame 4 are provided with axles 10a and 10b. Alternatively, the forest harvester may have one rocking axle and one dual wheel axle.
    Rolls may be arranged around the rings 11 of the rocking shaft 10a, 10b to increase the carrying capacity of the aircraft. Adjusting the width of the rings 11 supported by the axles and the width of the rolls li30 increases the loads on the axle, as well as increasing the load space and the mass transported. The solution presented in this application can prevent breakage of the transverse axis of the shaft system.
    Figure 2 illustrates the structure of the shafts 10 alone35. The shaft set 10 comprises a transverse shaft 12 which is modular and comprises a central body 13 and
    20185481 prh 25 -05-2018 two shaft tubes 14a, 14b attached to a central body 13. At each end of the transverse shaft 12, on either side of the implement body R, are rockers 15a, 15b on which the rings 11 are supported. The shaft set 10 is fixed to the implement frame R ki5 by crossing the coupling surfaces on the upper surfaces of the shaft tubes 14a, 14b with the vertical fixing screws 17 against the fixing surfaces in the frame R. Further, the axle assembly 10 is supported in the driving direction by means of horizontal mounting screws, which will be seen later in Figures 3 through 10. As shown in Fig. 2, one or more clamping devices 18 are provided on the underside of the transverse shaft 12 to pull the shaft tubes 14a, 14b.
    Figure 3 shows the shaft tube 14 and the clamping 15 for fastening the coupling members 19a, 19b of the devices 18a, 18b to the vertical fastening screws 17a, 17b.
    Figure 4 shows that the coupling members 19a, 19b of the clamping devices 18a, 18b are fixed to the horizontal fastening screws 20.
    Figure 5, in turn, shows that the clamping devices 18a, 18b are fastened by means of adapter pieces 21a, 21b to both vertical fastening screws 17a, 17b and horizontal fastening screws 20.
    Figures 6 and 7 show that the tensioning devices 25 18a, 18b may be mounted on the upper surface of the bottom armor 22, so that they are protected against impact from below. It is further seen that the clamping devices 18a, 18b are disposed on opposite sides of the central axis of the transverse shaft 12. In Figure 6, the upper surface of the bottom armor 22 is supported 30 against the lower surface of the transverse shaft 12. In Figure 7, the upper surface of the bottom armor 22 is provided with an upwardly projecting projection 23 which abuts against the lower surface of the transverse shaft 12.
    Fig. 8 illustrates a bottom armor 22 having a tensioner device 18 attached to the upper surface of the plate-like base portion 24. The tensioner device 18 comprises screw members 25 which allow the distance between the engaging means 19a, 19c to be
    20185481 prh 25 -05- 2018 change. The shaft 26a, 26b of the coupling device 18 may comprise threads. The clamping device 18 may be secured to the base member 24 by projections 27.
    Figure 9 illustrates a bottom armor 22 having a pivot portion 24 in the form of a rectangular plate body having two tensioning devices 18a, 18b arranged parallel to its long sides. The structure is otherwise similar to that shown in Figure 8. Further, Figure 9 shows that the bottom armor 22 may comprise drive openings 28 at the screw members 25 so that they can be actuated from below the shafts. The bottom armor plate portion may also have an opening 29 for the oil change plug and possibly a plurality of screw openings through which any mounting screws may be fitted to secure the bottom armor to the implement body.
    The bottom armor 22 shown in Figure 10 otherwise corresponds to the solution shown in Figure 9 except that the arms 26a, 26b of the clamping devices 18a, 18b are bent. The bent arms can facilitate the installation of the bottom armor. It should also be mentioned that the coupling means 19 may have a hinged coupling part or a coupling eyelet 30 having an opening for the fastening screw. The articulated coupling member allows positioning deviations between the coupling member and the retaining screw, thereby facilitating both installation and removal. The coupling loop 30 or coupling member 19 may also be without a joint or there may be more than one joint.
    The figures and the description thereof are intended only to illustrate the idea of the invention. However, the scope of the invention is defined in the claims.
