    Description of embodimentsFig. 1 shows an agricultural implement in the form of a disc implement, which isdesigned to be towed by a towing vehicle (not shown), such as a tractor.
    The agricultural implement comprises a frame 11, a roller 4, wheels 14 pre-adjustmentof deep holding and transport, soil tillage tools, here in the form of plates12a, 12b, and leveling gear 13 of the type marketed bythe applicant under the CROSSBOARD® brand. Frame 11 may comprise aleft section 11aL and a right section 11aR. Furthermore, the frame 11 may compriserespective frame frames 11bL and 11bR, respectively. By dividingframe 11 left sections 11aL, 11bL and right sections11aR, 11bRit is possible to fold the implement from a working position (Fig. 1) to a transport position(not shown), where the width of the implement may be significantly less than in the working position.
    It will be appreciated that the agricultural implement may comprise a single complete frame; onesplit frame with 1, 2, 3 or more folding sections. In all cases, it canthe tillage tool to be attached, via a suspension unit directly in the frame,or in an auxiliary frame, as is the case with the roller frame shown in Fig. 1.
    Between the roller 11 and the frame 11 is a suspension device 100arranged, which has the purpose of mitigating shocks that occur in, for examplevariations in the level or hardness of the cultivated soil and atstone hit. This allows the service life of both the roller and the frame1015202530improved, with improved reliability as a result. In the example shown,the roller 8 is suspended relative to the frame by two or more suspension members.devices 100.
    Figures 2-4 show a first embodiment of the suspension device 100.
    The suspension device comprises a bearing unit 110, a spring element 108 andfirst and second holder parts 107, 111. The suspension device 100 canmounted on a shaft 101, for example on a shaft provided with anarrower portion 103, so that a circumferential lug 102 is formed, which canact as an axial stop for the bearing unit 110. Furthermore, a firstcover plate 105 be designed as a tray with a through hole whosediameter corresponds to the narrower portion of the shaft 103. The washer may have an outerdiameter corresponding to an axial depression of one of the bearing units 110sleeves 1101, 1102. Furthermore, a sealing ring 109 (for example of rubber orrubber-like material) be arranged to for axial sealing ofthe bearing unit 110. A hub bolt 112 may be arranged to engage with onethreaded outer portion 104 of the shaft 101 to provide an axial lockof the bearing unit relative to the shaft 101. A second cover plate 113 may bearranged to prevent dirt from entering the bearing unit 110.
    The cover plate can be fixed by means of a press fit (for example with the help of ao-ring 115), snap fastener or locking ring.
    The suspension device 100 may further comprise first and secondholder parts 107, 111, which may be formed as a pair of molded orcast parts, which have a respective flat portion 1075, 1115 and arelative to the respective flat portion recessed portion 1076, 1116. The recessedthe portions may have axial openings 1077, 1117, intended for passageof shaft 101 and for access for mounting hub bolt 112 and / orcover plate 113. In the embodiment shown, the holder parts 107, 111 are identical.
    As an alternative, the holder parts can be designed as a pair of mirror facesparts. It is also understood that the holder parts do not have to be identical, butfor example can be designed as a first substantially completely flat part anda second part having a flat portion as well as a recessed portion, and where thisrecessed portion defines the entire space of the spring element.1015202530The recessed portions 1076, 1116 together define onespring space S, in which the spring element 108 can be fitted.the spring space may be designed so that the spring element 108 isadjustable during compression axially and / or radially, so thatthe spring member 108 is clamped in one or more directions.
    The spring member 108 is preferably formed of rubber or rubber.similar materials, which have the advantage of having both resilient anddamping (hysteresis) properties.
    The spring space S can be substantially rotationally symmetrical.
    Alternatively, the spring space may have one or more projections (not shown) aspushes in the spring space S and which can give rise to local larger onescompressions or deformations of the spring element 108. As furtheran alternative or complement, such committees may intervene with depressionsin the periphery of the spring element as described belowreference to Figures 5 and 6. As a further alternative, the spring space maybe divided into a plurality of sub-spaces, one or fl your spring elements beingarranged in each sub-space.
    The holder parts 107, 111 can be joined to fastening elements 106a-106c;114a-114c, such as bolted joints, as shown in Figs. 2-4.
    The holder parts 107, 111 can form a radially inwardly open, circumferentialwalking track Gi. The groove Gi may be continuous around its entire outer periphery.
    Alternatively, the track Gi may be discontinuous. The Gi's shape of the track can beadapted for abutment against the radially outwardly facing surface of the spring element 108.
    For example, recesses and / or projections in the walls of the track may bedesigned to coincide with committees and depressions ofthe outwardly facing surface of the spring element 108.
    The groove Gi can generally be designed with such a shape and suchdimensions that a sufficient axial lock relative to the spring element 108 canachieved. The depth DGi of the groove may be at least 10%, preferably at least 20% or at least 30% of the radial thickness of the spring element 108 calculated from itinner abutment surface to its outer abutment surface.
    The bearing unit 110 may comprise an inner ring 1101 and an outer ring 1102and friction reducing means arranged therebetween, such as roller bodies,1015202530plain bearing or hydrostatic storage device. As is commonly known, canthe inner ring and the outer ring comprise respective roller tracks for abutment againstrolling bodies. In the embodiment shown, the outer ring 1102 is formed with a radialoutwardly open, circumferential track Go. The Go track can be continuously roundthe entire periphery of the outer ring. Alternatively, the track may be discontinuous. The trackshape may be adapted to abut radially inwardly of the spring member 108facing surface. For example, recesses and / or projections in the walls of the trackbe designed to coincide with committees and depressions ofthe inwardly facing surface of the spring member 108.
    The Go track can generally be designed with such a shape and suchdimensions that a sufficient axial lock relative to the spring element 108 canachieved. According to one embodiment, the track Go may have a radius of curvatureRGo in an axial plane (Fig. 4), which is larger than a maximum radial thickness ofthe outer sleeve 1102. For example, the groove may have a surface curved in the axial plane,which has a radius of curvature RGo greater than 10%, preferably at least20% or at least 30%, of an axial width of the outer sleeve 1102. Depth of grooveDGo may be at least 10%, preferably at least 20% or at least 30% ofthe radial thickness of the spring element 108 calculated from its inner abutment surface toits outer abutment surface.
    As an alternative to an outer ring 1102 having a radially outwardly open,circumferential track Go, a standard "smooth" outer ring can be used, on whichan spare part (not shown) having the track Go is arranged. The extra part canarranged on such an outer ring by means of radial press fit, glue,welding, soldering, axially acting clamping joints, etc.
    Between a radial inner portion of the holder parts 107, 111 and a radialouter part of the outer ring (the wall forming the groove Go) there is onedistance Dr, which defines the largest theoretically possible radial motionbetween bearing unit 110 and the holder parts 107, 111, and which providesallowing the spring member 108 to expand when exposed to acompressive force during assembly and / or loading. Another such"Expansion space" can be formed in the radially outer portion of the spring space Sbetween parts 107, 111.
    The suspension unit 100 can be mounted as follows.1015202530A bearing unit 110, comprising an inner sleeve 1101 and a relativethis rotatable outer sleeve 1102, is arranged in the center of one or fl eraspring element 108, so that one integrated with the outer sleeve 1102,circumferential radially outwardly open track Go receives a radially seen inner portionof the spring member 108. The spring body 108 may be threaded onto the bearing assembly 110substantially axially. This intervention can be facilitated by utilizinglubricants, such as soap, detergent, oil or the like. This fixesthe spring member 108 both axially and radially relative to the outer sleeve 1102.
    A next step may be to clamp axially and / or radiallythe spring element relative to the holder.
    According to one embodiment, the spring element 108 is clamped in a spring space S.formed in a holder so that the spring member 108 is substantially fixed as wellaxially and radially relative to the spring space S. The holder can in turn be formed bytwo parts 107, 111 as described above which are joined in the axial direction,so that the spring member 108 is clamped at least axially.
    It will be appreciated that while the above description shows utilization of onesingle- or two-row radial ball bearings, other types of bearings can also be used,such as any single or multi-row roller bearing, plain bearing or hydrostaticstock. Angular contact bearings can be particularly suitable.
    The spring element shown in Figs. 2-4 consists of a rotationally symmetrical onebody with circular cross-section and axis of rotation located outside the circularthe cross section. Cross-sections other than circular, for example, the cross-section may bepolygonal (triangular, rectangular, square, etc.) or elliptical.
    Fig. 5 shows a spring element 108 ', with a spring body 1081' and acenter hole 1082 ”. The radially outwardly facing surface of the spring body has a pluralityradial recesses 1083 ”. These depressions can, but must not,fit into corresponding radially inwardly extending projections of the groove Gi.
    The spring elements 108, 108 'of Figs. 2-4 and 5 are substantially isotropicspring characteristics at radial load from different angles.
    Fig. 6 shows an embodiment of a spring element 108 ", with aspring body 1081 ”and a center hole 1082” but with asymmetricalarranged radially inwardly extending recesses. This spring element has101520253010thereby anisotropic spring characteristics under load from different radialdirections.
    It will thus be appreciated that the spring element may have anisotropic spring characteristics.
    For example, the spring body can be made stiffer at substantially horizontalradial loads than at substantially vertically radial loads, in order tothereby allowing upward suspension in the event of a collision with an obstacle, but limitingsuspension in substantially horizontal directions. As an alternative or complementthe spring element can have different characteristics when loaded from the axis of rotationand down and up respectively.
    For example, a geometry and / or suspension characteristics may be similarthe one shown in SE457225B is achieved.
    According to further embodiments, the spring element can be constituted by abody which in the unloaded (undeformed) state is essentially polygonal(triangular, rectangular, square, etc.), elliptical (oval), etc. Under loadthe body can be deformed so that it fully or partially follows one or bothtrack's Gi, Go form.
    According to further embodiments, the spring element can consist of twoor more spring element parts, which may be arranged next to (optionallyabutting each other along the tracks Gi, Go, or which may be arrangedat a distance from each other along the tracks Gi, Go. The spring element parts canbe connected to each other by, for example, glue, vulcanization or one orseveral connectors.
    IHAccording to an embodiment shown in Fig. 7, the spring element 108 maycomprise a plurality of spring member portions 1081 "', which may be in the form of balls ofresilient materials, which may be arranged next to each other along the grooves Gi,Go or with fixed at predetermined angular positions in a plane to which the bearingaxis of rotation A1 is normal. The bearing is thus arranged in a center hole 1082 "'.defined by the group of capercaillie member parts 1081 The angular positions canfixed by means of the radially inwardly extending projections described above inthe track Gi and / or by means of radially outwardly extending projections in the track Goand / or by means of a separate connector, similar to the type ofball holders that are often used in ball bearings.101520253011The spring element 108 "shown in Fig. 9 is asymmetrical in thatit has a center hole 1082'V, which is radially offset relative tothe periphery of the spring body 1081 'V. Thereby a spring element is provided withdifferent long suspension travel in different directions.
    The spring elements as above can be solid, hollow, or evenwith partially open (such as C- or U-shaped). In Fig. 8 asuspension device 100 'with an alternative embodiment of holder 107', wherethe holder is designed as a single part, which is permanently composed of onemounting portion 1075 'and a spring receiving portion 1076'. Mounting part1075 'may be substantially flat, while the spring receiving portion 1076'can be substantially circular about the axis A1 (ie in the plane P1), andhave at least one in an axial plane (a plane containing the axis A1-fig. 8)curved inner surface forming the groove Gi ”. Even the fi honor-receiving partyouter surface may be curved in the axial plane.
    The mounting portion 1075 'may be formed of a flat blank, for example ofmetal. The spring receiving portion can be formed by a tube portion, with a lengthwhich approximately corresponds to the axial length of the bearing unit 110, the wall of the tubeshaped so that a curvature in the axial plane is achieved. Such shaping can take placeby, for example, press forming. The portions 1075 ', 1076' can be joinedby, for example, welding or soldering.
    Casting of the portions 1075 ', 1076', followed by joining as above,or casting the entire alternative holder 107 'in one piece are secondalternative.
    In the suspension device 100 'shown in Fig. 8, the bearing and itsattachment and seal to shaft 101 be identical to what is shown anddescribed with reference to Fig. 4.
    Mounting of the suspension device 100 'shown in Fig. 8 canachieved by substantially axial pressing, in the same way asdescribed above regarding mounting of the spring member 108 onthe bearing unit 110. Alternatively, the shaping of the spring receiving portion may1076 'occur wholly or in part after the spring element 108 has been positioned inlot 1076 '.101520253012Fig. 10 shows a further alternative embodiment of a suspension unit100 ", which is adapted to accommodate larger axial loads on the shaft 101 'one way (to the right in Fig. 10) than the other way. In this embodiment isthus at least one of the radially outwardly open track Go ”and the radial oneinwardly open the groove Gi ”asymmetrically, insofar as the walls delimitingthe track in the axial direction has different heights relative to the deepest part of the track Gi ", Go".
    A thus modified track Go ”can thus occur on the outer ring1102 'together with either a normal track Gi, Gi' (as shown in Figs. 4, 8)at the holder 1076, 1076 'or together with a modified groove Gi' atholder 1076 ”.
    In the same way, a modified groove Gi ”can occur at the holder1076 "together with a normal Go or modified Go" track atouter ring 1102, 1102 '.
    The holder or holder parts may have holes 1111a, 1111b, 1111c, 1111d;1071a, 1071b for attaching the suspension device 100 relativethe frame 11 of the agricultural implement 1 by means of screw joints, bolt joints orother preferably detachable dressing.
    Gear 10 is typically mounted on the shaft 101, so that rotation ofthe tool relative to the frame 11 is provided via the bearing unit 110 and the restrelative motion (damped and sprung translational motion) between gear 10 andframe 11 is provided via the spring element 108, 108 ', 108 "The description above shows gear in the form of a roller, but itshown suspension device can also be used for other rotatable implements,such as disc gear (harrow discs, seed discs), packer wheels, etc.
    The suspension devices according to the above find special application ingear comprising at least one shaft, which has two, three or more, in at leastlaterally, separate attachments relative to the frame. For example, a shaft may have onesuspension device as above at each end. According to anotherfor example, a shaft may have a suspension device at an intermediate portion.
    According to another example, a shorter shaft may be provided with only onesuspension device as described above.
    A suspension device as described above can, as non-restrictive example, used for suspension between a tool and a13main frame 11, a side section frame 11aL, 11aR or a tool frame (such asen vä | tram) 11bL, 11bR.
