    Arrangement for stabilization of the working machine and working machine
    Background of the invention
    The invention relates to mobile machines such as forestry machines such as harvesters and forwarders. Forestry machines are used to cut down 5 trees, prune them, cut the cut tree trunk into pieces of a certain size, and load and transport the timber obtained in the above-mentioned way.
    Difficult conditions such as poorly bearing ground or hills, slopes or other rising or falling terrain form problems with the mobility and stability of the machine. In addition, a heavy implement extending beyond the implement, such as a boom harvester head or a boom handling grapple, impairs the stability of the implement.
    Some previously known structures for stabilizing an implement include additional weights at the front of the implement and the use of hydraulic firearms, but the additional weights 15 increase the mass being transported and hydraulic firearms cannot be used while the implement is moving. In addition, it is known from the past that the use of a bogie structure improves stability but it is expensive in structure.
    Fl-8939 discloses an arrangement in which an auxiliary wheel is mounted at the end of a support arm mounted on a machine frame, but that arrangement is due to the rigid connection between the support arm and the auxiliary wheel such that it does not allow the machine to be used with rollers because the distance between the axis of the machine and the wheel in the up-and-down movement of the support arm as a result of the terrain shapes would cause problems with the roll tension. Furthermore, the arrangement 25 of F1-8939 is not even intended for use with a roller because the auxiliary wheel is not in the line of rotation of the actual wheel of the implement but the auxiliary wheel is in the center of the rear of the implement attached to drawbars in the area between the actual pair of wheels.
    Brief description of the invention
    The object of the invention is thus an arrangement and a working machine so that the above-mentioned problems can be solved. The object of the invention is achieved by an arrangement and a working machine which are characterized by what is stated in the independent claims. Preferred embodiments of the invention are the subject of dependent claims.
    20185703 prh 28 -08- 2018
    The invention is based on the fact that the support of the auxiliary wheel hub on the support arm is such that it allows the auxiliary wheel hub and thus also the auxiliary wheel to move along the support arm.
    The arrangement and the working machine according to the invention have the advantage of improving the load-bearing capacity and stability in a way which also enables the use of rollers. By means of the arrangement, the position of the auxiliary wheel adapts to the co-operation with the roller and the terrain and enables automatic tension adjustment of the roller, i.e. the track / track.

    Detailed description of the invention
    With particular reference to Figures 1-2, the invention is applied in connection with a working machine 1 such as a forestry working machine 1. The working machine 1 comprises the actual wheels Wil, W12 and W21, W22 with their axes A1, A2. There are, of course, two actual wheels for each fixed axle A1, A2. In addition, the working machine comprises, on the front part of its 2-part frame, an engine M such as a diesel engine and on the rear part FR2 of its body a cab 2 and an implement 3 30 such as a boom B with a processing head HH. The implement 1 is frame-controlled, i.e. the front part and the rear part of the 2-part frame can be turned relative to each other. In Fig. 1, the working machine further comprises rollers TRI, TR2, i.e. track chains / track mats. The stability-improving auxiliary wheels AW1, AW2 shown in the other figures 3-5 are also visible in Figures 1-2, and in connection with Figure 1 it can be seen that the roller TRI rotates through the actual wheel W21 resting on the rear axle A235 and the first auxiliary wheel AW1, and
    20185703 prh 28 -08- 2018 that the roller TR2 rotates through the second actual wheel W22 resting on the rear axle A2 and the second auxiliary wheel AW2. In particular, it can be seen from Figures 3-4 that the rear axle A2 and the actual wheels W21, W22 resting on it rest on the rear part FR2 of the frame.
    Referring to Figures 1 to 6, the working machine 1 has sections 100, 200 on each side. ] and which stabilization arrangement is the exploded view shown in Fig. 5.
    This is therefore the actual wheels of the stabilized arrangement 100
    W21, W22 for stabilizing a working machine 1 such as a forestry machine or other working machine. The arrangement comprises a bearing structure B1 and, with that bearing structure, a support arm SAI rotatably mounted vertically on the frame FR2 of the working machine. In addition, on the outer end side of the support arm SAI, the arrangement comprises a wheel hub WB1 supported by the arm SAI for the auxiliary wheel AW1 and an auxiliary wheel AW1. The arrangement further comprises a hydraulic actuator HAI for changing the position of the wheel hub WB1 and thus also the auxiliary wheel AW1.
    In the stabilized arrangement, the wheel hub WB1 of the auxiliary wheel 100 is supported on the support arm SAI by a sliding support structure 20 GS1 connected to the wheel hub WB1, to enable the movement of the auxiliary wheel AW1 in the direction of the support arm SAI on the support arm SAI. In one embodiment, the sliding support structure GS1 of the auxiliary wheel hub comprises vertical facing plate parts GS11, GS12 which are releasably fastened to each other by fastening means GSB, GSN. The plate parts GS11, GS12 of the sliding support structure delimit the t25 to the support arm GS13, as clearly illustrated in Fig. 6. In addition to the plate parts GS11, GS12 and the fastening means GSB, GSN, the sliding support structure GS1 may comprise support pieces GS15, GS16 as sliding pieces according to Fig. 5.
    The operating arm HAH of a hydraulic actuator such as a hydraulic cylinder HAI is connected via a rotating attachment HA1A to affect the movement GS1 of the sliding support structure of the wheel hub WB1 of the auxiliary wheel 30 AW1. The pivotal attachment of the hydraulic arm HA11 of the hydraulic cylinder HA11A to the sliding support structure GS1 is, as can be seen more clearly in Figures 3-5, the pivotal attachment of the second hydraulic cylinder HA2 the operating arm HA21 to the sliding support structure GS200 of the second support arm SA2 of the working machine.
    When the stabilizing arrangement 100 is in a working machine with a track TRI rotating through the actual wheel such as W21 and the auxiliary wheel AW1, it is hydraulic
    20185703 prh 28 -08- 2018 actuator A1 connected to move the auxiliary wheel AW1 on the support arm SAI, enabled by the auxiliary wheel slide support structure GS1, to maintain the tension of the track TRI.
    The hydraulic actuator HAI has a pressure setting when the implement moves, which is why the hydraulic actuator HAI with its movement arm HAH, i.e. with its piston pushes the auxiliary wheel AW1 wheel hub WB1 sliding support GS1 outwards on the support arm SAI if the terrain shapes cause the support arm HAI to rotate.
    Correspondingly, the pressure setting of the hydraulic actuator HAI allows the movement arm HAH to retract on the auxiliary wheel AW1 wheel hub WB1 sliding support GS1 inwards on the support arm SAI if the terrain shapes cause the support arm SAI to rotate.
    In roller operation, the slide support structure GS1 enables the auxiliary wheel AW1 to compensate for the distance between the auxiliary wheel AW1 and its wheel hub 15 WB1 from the axle line of the actual wheels W21, W22 of the implement. This is important because the location of the auxiliary wheel affects the contact of the auxiliary wheel with the inner surface of the roll because the roll TRI 20 forms a closed circumference through the actual wheel W21 and the auxiliary wheel AW1. The wheel hub WB1 of the auxiliary wheel AW1, i.e. also the axial line of the auxiliary wheel, is at a different point, i.e. outer or closer to the rear edge of the implement, than the axial line of the actual wheels W21, W22.
    In one embodiment, the bearing structure B1 enabling the vertical rotation of the support arm SAI is a plate-like vertical structure comprising a housing member BIO and a circularly symmetrical base B
    Further related to the bearing structure B1, it is the case that the circularly symmetrical housing B11 in the housing body BIO comprised by the bearing structure B1 is at least as deep in the transverse direction as the circularly symmetrical base SA1B of the support arm SAI. The support plate structure for covering the housing comprises a support plate B12
    20185703 prh 28 -08- 2018 on the outermost vertical side of the housing BIO, which in Figures 3-5 is the left side of the housing BIO as it faces the outer edge of the implement.
    Referring to Figures 3-5, the bearing structure comprises a replaceable! between the base SA1B 5 of the support arm SAI of the fixed planar body B13 and the machine body FR2. This interchangeable planar surface B13 between the support arm base SA1B and the machine body FR2 may be an integral part of the housing BIO, or a separate planar B13 may also be seen as part of the support plate structure, i.e. it can be seen as a pair for the support plate B12, especially if the housing B11 in the housing BIO transverse10 direction.
    In particular, it can be seen from Fig. 5 that the bearing structure comprises fastening means B20 with which the housing piece BIO can be detachably fastened to the frame FR2 of the working machine 1. The fastening means B20 may be bolts, in which case both the support plate B12, the housing piece BIO and also the flat surface piece B13 (second support plate) 15 have openings for the bolts B20, and the body FR2 has a threaded housing for the bolts B20 or the body has openings for the bolts. . The replaceable flat surface piece B13 is fastened by the same fastening means B20 as the housing piece BIO and the support plate B12.
    In particular, it can be seen from Fig. 5 that the periphery of the housing B11 20 of the housing body BIO comprises an open rotation space for the rotation movement of the support arm SAI delimited by the opening edges E1, E2. The opening edges E1, E2 limit the excessive rotation of the support arm SAI, i.e. the rotation in the vertical plane.
    The housing piece BIO and the housing and the support arm SAI base part SA1B settling in the housing is one embodiment. Thus, more generally, it can be seen that the bearing structure B1 enabling the vertical rotation of the support arm SAI is a plate-like vertical structure comprising a circularly symmetrical support portion BIO, the bearing structure SA covers the support portion BIO, Bll and the support arm SAI base portion SA1B.
    Thus, the bearing structure B1 may be as shown in the figure and above, i.e. that the rotating support arm base SA1B is in the housing BIO housing, i.e. that the support arm SAI support portion BIO is around the support arm base SA1B, but the structure may be inverted, i.e. the support arm base around the support part, in which case there would be an opening / housing for the support part in the base part of the support arm. Also in this embodiment there would be similar additional features as
    20185703 prh 28 -08- 2018 in the version shown in the figures, i.e. e.g. the fact that the support part attached to the frame FR2 should be removable / replaceable and in addition the flat surface piece (such as B13) must be removable / replaceable.
    In one embodiment, in particular according to Figures 3-5, the support arm SAI comprises at the outer end of the support arm SAI a stop R to limit the movement of the slide support GS1 and thus also the wheel hub WB1 of the auxiliary wheel AW1 and the auxiliary wheel AW1. It is so that when the implement is operated without rollers, the hydraulic actuator HAI is arranged to push the wheel hub WB1 of the auxiliary wheel AW1 against the stop R, in which case the position of the slide support GS1, the wheel hub WB1 of the auxiliary wheel AW1 10 and the auxiliary wheel AW1 is locked. The sliding support structure GS1 comprises a mating piece NI, N2 for the stop R, the mating piece NI, N2 may be a recess in the sliding support structure, for example a recess N in the plate parts GS11, GS12 of the sliding support structure. The upper support arm SAI also has a second stop and also has in its plate parts GS11, GS12 a counterpiece such as a recess, to stop the sliding15 support structure GS1 in the reverse or inward movement along the support arm SAI.
    The machine also has a second stabilization arrangement section, i.e. stabilization arrangement 200. Its structures are similar to those shown above for the insurance arrangement 100. The second securing arrangement 200 actuator HA2. Correspondingly, that second insurance arrangement 200 also comprises a slide support structure GS200 for the wheel hub WB2. The support arm SA2 also has a bearing structure similar to that shown above for the support arm SA1 with reference to the bearing structure B1a. The stop for the GS200 slide support structure is marked R2. The implement has its own arrangement for stabilizing 100 and 200 implements for each side, respectively. On each side of the implement, the arrangement is such that the auxiliary wheel AW1 and AW2 comprised by the arrangement are in the same longitudinal line as the female wheel W21, respectively W22 of the implement arm. The roller TRI, respectively TR2, rotates both the actual wheel W21, respectively W22 and the auxiliary wheel AW1; respectively via AW2.
    The support arms are located away from the longitudinal centerline of the implement, i.e. outer, and the distance between the support arms SAI, SA2 widens towards the outer ends of the support arms SAI, 35 SA2, thus making it easier to align the wheel hubs WB1, WB2 with the actual wheels W21, W22 movement on uneven terrain.
    It will be apparent to one skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments 5 are thus not limited to the examples described above but may vary within the scope of the claims.
