    Arrangement and method of floating the cab of a machine tool
    Background
    The invention relates to work machines, and in particular to an arrangement and a method for levitating a work machine cab.
    The longitudinal and transverse oscillations of the machine cab when traveling on uneven terrain cause significant problems for the driver's ergonomics. In addition, when the machine is stationary to perform its tasks, it is essential for the ergonomics of the driver that the cab and driver's workstation can be quickly moved to a position substantially on a horizontal platform. In the forest machine environment, terrain inclines and unevenness may be considerable, which would require relatively large operating margins and levellation angles. However, the problem often arises with the relatively narrow layout of the forestry machine, in which the longitudinal space of the machine in particular is typically quite limited.
    Short description
    It is therefore an object of the invention to provide a new arrangement and method for fluttering a cab of a work machine, characterized by what is stated in the independent claims. Preferred embodiments of the invention are disclosed in the dependent claims.
    The invention is based on the fact that the arrangement comprises longitudinal fluttering means for fluttering the cab in the longitudinal tilt of the implement and transverse fluttering means for fluttering the cab in a transverse lateral tilt of the implement. The transverse pivot axis extends substantially perpendicular to the longitudinal pivot axis and is disposed at a height lower than the longitudinal pivot axis.
    An advantage of the method and arrangement is that the cab oscillation can be significantly limited by an arrangement that minimizes the need for additional space, particularly in the longitudinal direction of the machine, whereby a certain longitudinal fluttering maneuver can be provided on a shorter working machine and / or In other words, the method and arrangement of the machine-tool of a certain length can, thanks to the method and arrangement now shown, provide greater maneuverability and greater flutter angles 35, at least with respect to longitudinal fluttering of the cab.
    20176202 prh 29 -12- 2017 suits. In addition, the solution can improve driver ergonomics by adapting known cabs to known body parts. In other words, the solution is also well suited for modular production.

    The mobile working machine 10 may comprise one or more frame members 11 and 35 fitted with a cab 12 mounted on at least one of the frame parts.
    20176202 prh 29 -12-2017 provides means for moving 13, which means may comprise at least one of: axle-mounted wheels, swivel-axle wheels, bogie-mounted wheels, to control the implement with respect to its work platform. It will be apparent to one skilled in the art that the implement typically further comprises a variety of structural and functional components and assemblies dependent upon the type of implement, such as boom 14, load 15, tool (not shown), power source 17, and so forth. The tool may comprise, for example, a lifting device, such as a loading bucket, and / or a woodworking tool, such as a harvester head.
    The mobile work machine 10 may further comprise an arrangement 1 for floating the cab 12 of the work machine 10. The cab 12 may be adaptable to at least one frame member 11 of the implement 10. "Levellating" herein refers to tilting the cab 12 towards a horizontal position from obstacles and contours of the work platform and tilting them to the frame portion of the implement 10, particularly the cab 15. despite. In other words, levellation can guide the cab to a desired position, for example, a horizontal position with respect to the longitudinal tilt and / or lateral tilt of the machine, regardless of the tilt caused by the work platform when the oh20 station 12 is fitted to the working unit.
    Fig. 2 schematically illustrates an arrangement 1 for floating the cab of a working machine 10. Arrangement 1 may comprise longitudinal flapping means 2 for fluttering the cab in the direction A of the longitudinal tilt of the implement. In other words, the cab 12, shown by the dotted line in Figure 2, can be guided 25 towards the horizontal position with respect to the longitudinal tilt A of the implement by means of longitudinal levellation means 2. In one embodiment, the arrangement 1 for levitating the cab of a working machine 10 may further comprise transverse levellation means 20. In Figure 2, these transverse levellation means are depicted by a dashed line. Figures 3-9 schematically illustrate some of the various embodiments of such an arrangement, details and principles of such embodiments.
    Fig. 3 schematically shows an embodiment of the arrangement 1 for floating the cab 12 of a working machine in perspective and Fig. 4 shows an exploded view of the embodiment of Fig. 3 in perspective. As will be apparent to one of ordinary skill in the art, in Fig. 4, the cab 12 and arrangement 1 are shown at a different angle than in Fig. 3.

In Fig. 5a, arrangement 1 is shown in lateral view and Fig. 5b is a rear view. For example, although Figures 3-5b and 5 8-9 show embodiments in which arrangement 1 comprises both longitudinal levellation means 2 and transverse levellation means 20, arrangement 1 may not necessarily comprise transverse levellation means 20 in all embodiments.
    The longitudinal hinging means 2 may be adapted to connect the cab 12 to the body of the implement 10, more particularly to at least one of the frame members 10 11, pivotally and substantially perpendicular to the longitudinal axis B of the implement frame. In other words, the longitudinal levellation means 2 may be arranged to float the cab 12 with respect to the longitudinal tilt A of the work machine, i.e. to steer the cab toward the horizontal position through arrangement 1. Depending on the embodiment, levellation can then be done by rotating the cab 12 relative to the longitudinal pivot axis C or by allowing the cab 12 to rotate with the longitudinal pivot axis C.
    Preferably, the longitudinal pivot axis C is disposed relative to the work machine cab substantially on a line at which the cab length D in the longitudinal direction B of the machine body is greatest when arrangement 1 is fitted to at least one body member 11 of the machine 10. where the cab is longest in the longitudinal direction of the machine, or at a distance of up to 0.2 m from such a line when the arrangement is fitted to the machine, i.e. at least one frame 11 of the machine 10. This allows the cab 12 to float at minimum
    Figure 5a embodiment, the line at which the length of the cab of the working machine body in the longitudinal direction is the largest, is substantially in the direction of arrow D, and extends in the neutral position of the cab 12 of Figure 5a, a kallistumattomassa position in the horizontal direction. In other words, the length D of the cab is the maximum length in the longitudinal direction B of the machine tool extending parallel to the longitudinal direction B of the machine frame.
    20176202 prh 29 -12- 2017
    The points defining cab length D are then in the cab's neutral position on the same horizontal line.
    In one embodiment, the longitudinal pivot axis C may be disposed in the longitudinal direction of the machine, i.e. in the longitudinal direction B of the machine frame, in the middle third of the station 12 as viewed along a line at which the longitudinal length of the machine. In other words, the longitudinal pivot axis C may be disposed in the mid-third of the line defining the maximum length D in the longitudinal direction B of the cab machine. This area is thus, viewed from the side, as in Figure 5a, located in the middle third of the cab 12.

    In Fig. 5a, the center or center of the line at which the length of the cab is largest in the direction of the implement 20 is substantially at the same position as the vertical axis G.
    Figures 5a and 5b schematically show some longitudinal articulation means 2 and the longitudinal articulation axis C formed by them.

    In one embodiment, the longitudinal levellation means 2 comprises at least one first actuator 3 which is adjustable to guide the cab 12 towards a horizontal position with respect to the longitudinal tilt A of the working machine 10. In other words, the first actuator 3 may be adjustable to guide the cab 12 towards a horizontal position with respect to the longitudinal tilt A of the implement 10 when the arrangement 1 is fitted to the implement 10, in particular at least one frame member 11. The first actuator may comprise for example, at least one hydraulic cylinder.

That is, the longitudinal guide may have a curved appearance, but in all embodiments it need not be curved if the engagement of the mounting structure 5 with the longitudinal guide 4 is otherwise arranged to provide a curved trajectory of cab 12 corresponding to rotation about the longitudinal pivot axis C.
    In one embodiment, as in the embodiment of Figure 4, the curved longitudinal guide 4 is concave in shape such that the lowest point of the trajectory formed by the curved longitudinal guide 4 is in the longitudinal direction of the curved longitudinal guide 4.

The mounting structure 5 may comprise at least one first slider curved longitudinal guide 4.

The transverse pivot axis J can then extend substantially horizontally perpendicular to the longitudinal pivot axis C. In one embodiment, the transverse pivot axis J may be so20 lowered at a lower height than the longitudinal pivot axis. This is particularly advantageous because the wheelbase in the transverse direction of the implement is typically considerably shorter than in the longitudinal direction of the implement. Then, the transverse oscillation axis, i.e. in this embodiment, the transverse articulation axis J, is preferably arranged as low as possible. This also reduces the lateral or transverse displacement of the cab during the cab flutter as the machine 10, more specifically the body 11 of the machine, tilts. Particularly preferably, the transverse pivot axis J may be disposed below the PTO shaft of the cab and the implement 10 while the arrangement 1 and the cab 12 are mounted on the implement 10.

    In one embodiment, as in the embodiment of Figure 4, the transverse diverting means 20 may comprise at least one curved transverse guide 21 having a center of curvature centered on the transverse articulation axis 10. The transverse pivot axis J may further be arranged at a height lower than the longitudinal pivot axis C.

    20176202 prh 29 -12-2017 towards the horizontal position with respect to the transverse tilt H of the implement 10. That is, the second actuator 24 may be adjustable to guide the cab 12 toward a horizontal position with respect to the transverse tilt H of the implement 10 when the arrangement 1 is fitted to the implement 10, in particular at least one frame member 11. The second actuator 24 may comprise e.g. , for example at least one hydraulic cylinder. In one embodiment, the transverse levellation means 20 may comprise at least one second actuator 24, the second actuator being disposed on the one hand, the transverse guide 21 or the curved transverse guide 21, with respect to the inclination H, such that the second actuator 24 causes a movement forming a mutual curved path of motion between the curved transverse guide 21 and the curved longitudinal guide 4. In this case, the calculated center of curvature of the curved path may lie on the transverse pivot axis J.
    In one embodiment, such as the embodiment of Figure 4, the curved transverse guide 21 is convex in shape with the highest point of the trajectory formed by the curved transverse guide 21 extending longitudinally in the middle of the curved transverse guide 21. In other words, the curved transverse guide 21 may be arranged in arrangement 1 such that, in its operating position, e.g. transverse to the central direction of the transverse guide.
    Fig. 7 schematically shows a working machine 10 comprising an arrangement 1 for fluttering the cab. The arrangement 1 may comprise, for example, one of the arrangements 1 described in this specification and in connection with the other figures for controlling the plurality.
