    PIVOTING CONNECTION DEVICE BETWEEN AT LEAST TWO PARTS, AIRCRAFT COMPRISING A COVER EQUIPPED WITH SAID PIVOTING CONNECTION DEVICE
    The present application relates to a pivoting connection device between at least two parts as well as to an aircraft comprising a cover equipped with said pivoting connection device.
    According to a configuration visible in FIGS. 1 and 2, an aircraft 10 comprises several engine assemblies 12 which are positioned under the wing 14 of the aircraft 10.
    An engine assembly 12 comprises an engine 16, a nacelle 18 positioned around the engine 16 and a mast 20 which provides the connection between the engine 16 and the rest of the aircraft 10, in particular the wing 14.
    The nacelle 18 comprises at least one cover 22 connected to the rest of the nacelle 18 by a hinge 24 allowing the cover 22 to pivot around a pivot axis A24 between an open position (visible in FIG. 2) and a closed position ( visible in Figure 1).
    According to one configuration, the hinge 24 has several pivoting connection devices 26 distributed along the pivot axis A24.
    According to a first embodiment visible in FIG. 3, a pivoting connection device 26 comprises:
    a yoke 28, secured to the cover 22 (or respectively of the rest of the nacelle 18), having two branches 28.1, 28.2, an arm 30, secured to the rest of the nacelle 18 (or respectively of the cover 22), positioned between the branches 28.1 , 28.2 of the yoke 28, a cylindrical axis 32 positioned in coaxial bores provided in the two branches 28.1, 28.2 of the yoke 28 and the arm 30, said cylindrical axis 32 ensuring the connection between the yoke 28 and the arm 30 and having an axis of revolution coincident with the pivot axis A24.
    Guide rings can be inserted between the cylindrical axis 32 and the branches
    28.1, 28.2 of the yoke 28 as well as between the cylindrical axis 32 and the arm 30.
    The pivoting connection device 26 also comprises first and second stops 34, 36, positioned on either side of the branches 28.1, 28.2 of the yoke 28, to immobilize in translation the cylindrical axis 32 relative to the branches 28.1, 28.2 in a direction parallel to the pivot axis A24.
    According to this first embodiment, the cylindrical axis 32 has at a first end a head 38 which forms the first stop 34 and which is configured to bear against the external face F28.1 of the first branch 28.1 of the yoke 28.
    The second stop 36 is in the form of a split pin 40 which crosses the cylindrical axis 32 and which is configured to bear against the external face F28.2 of the second branch 28.2 of the yoke 28.
    This first embodiment requires that the two sides of the yoke 28 are accessible in order to be able to assemble the pivoting connection device, the cylindrical axis 32 being introduced from a first side of the yoke 28, the cotter pin being put in place from a second side of clevis 28.
    According to a second embodiment described by document FR-2,947,592 and illustrated by FIGS. 4 to 6, a pivoting connection device comprises, in addition to the yoke 28 and the arm 30, a connection system comprising:
    a tubular body 42 which has, at a first end a flange 42.1 configured to bear against the external face F28.1 of the first branch
    28.1 of the yoke 28 and, at a second end, at least one slot 42.2 allowing the second end of the tubular body 42 to expand radially, an insert 44 of frustoconical shape positioned inside the tubular body 42, at the level of its second end, having a tapped bore 44.1, and a screw 46, configured to be housed in the tubular body 42 having, at a first end, a head 46.1 configured to be pressed against the flange
    42.1 of the tubular body 42 and, at a second end, a threaded section 46.2 configured to be screwed into the threaded bore 44.1.
    The screwing or unscrewing of the screw 46 brings the insert 44 and the head 46.1 of the screw 46 closer together or apart. When the insert 44 and the head 46.1 of the screw 46 are in the separated state , the second end of the tubular body 42 is not radially expanded. When the insert 44 and the head 46.1 of the screw 46 are in the close state, the second end of the tubular body 42 is radially expanded.
    According to this second embodiment, the insert 44 and the head 46.1 of the screw 46 being in the separated state, the connection system is inserted into the bores of the branches 28.1, 28.2 of the yoke 28 and of the arm 30 from a first side of the yoke 28. When the connection system is inserted, the head 46.1 of the screw 46 and the insert 44 are brought together by screwing the screw 46, from the first side of the yoke 28, so as to cause the expansion of the second end of the tubular body 42.
    Thus, according to this second embodiment, the collar 42.1 of the tubular body 42 forms a first stop making it possible to immobilize the tubular body 42 in a first direction. The expansion of the second end of the tubular body forms a second stop making it possible to immobilize the tubular body 42 in a second direction, opposite to the first direction. The friction between the tubular body 42 and the second branch 28.2 of the yoke 28, due to the radial expansion of the second end of the tubular body, also contributes to the immobilization of the tubular body 42 relative to the second branch 28.2.
    This second embodiment allows the assembly of the pivoting connection device from one side of the yoke 28.
    However, this second embodiment induces significant radial loads in the bore of one of the two branches 28.2 of the yoke 28 due to the expansion of the second end of the tubular body 42.
    The present invention aims to remedy the drawbacks of the prior art.
    To this end, the subject of the invention is a pivoting connection device connecting at least two parts and comprising:
    a yoke, integral with the first part, having first and second branches each comprising an inner face oriented towards the other branch and an outer face opposite the inner face, as well as a bore which opens at the inner faces and outer, an arm, integral with the rest of the second part, positioned between the first and second branches of the yoke and having a bore, a cylindrical axis, configured to be housed in the bores of the first and second branches and of the arm, forming a pivot axis, at least one guide ring, interposed between the first branch and the cylindrical axis, comprising a tubular body which has a collar configured to bear against the inner face of the first branch in order to block the guide ring by relative to the first branch in a direction parallel to the pivot axis, in a first direction.
    According to the invention, the pivoting connection device comprises:

    Thus, the pivoting connection device can be assembled from one side of the yoke. According to another advantage, the pivoting connection device does not induce any radial load in the bore of one of the branches, unlike the second embodiment of the prior art. Finally, none of the other parts of the pivoting connection device is subjected to stresses in the locked state.
    According to another characteristic, the guide ring comprises an extension projecting relative to the external face of the first branch, the extension having at least one slot allowing it to expand radially in an elastic manner; the immobilization system comprises at least one groove, which extends in a transverse plane on a peripheral face of the cylindrical axis, and at least one rib having shapes complementary to those of the groove at an interior face of the extension of the guide ring in contact with the peripheral face of the cylindrical axis when the extension is not radially expanded.
    According to one configuration, the groove and the rib have identical trapezoidal sections and each have two flared side walls.
    According to another characteristic, the locking system comprises a thread at the level of a section of the tubular body of the guide ring projecting from the outside face of the first branch and a locking nut having a threaded bore configured to be screw on the thread, the blocking system being in the blocked state when the blocking nut, screwed on the thread, is in contact with the external face of the first branch.
    According to another characteristic, the pivoting connection device comprises a locking system configured to prevent the immobilization system from going from the locked state to the free state.
    According to one configuration, the locking system comprises a locking ring configured to fit onto the extension and prevent the rib from coming out of the groove.
    According to another characteristic, the locking nut and the locking ring form only one single piece.
    According to a first embodiment, the locking ring has an inside diameter greater than the outside diameter of the extension and less than the outside diameter of the extension increased by twice the height of the rib.
    According to another embodiment, the unlocking ring has a slightly frustoconical internal surface, so as to exert a slight radial pressure on the extension when the unlocking ring is fitted.
    The invention also relates to an aircraft comprising a cover equipped with at least one pivoting connection device according to one of the preceding characteristics.

    According to one configuration, each branch 58 (or 60) comprises an internal face FI58 (or FI60), oriented towards the other branch 60 (or 58), and an external face FE58 (or FE60) opposite the internal face FI58 (or F60). The internal faces FI58, FI60 and the external faces FE58, FE60 are mutually parallel and positioned in transverse planes.
    Each branch 58 (or 60) comprises a bore 66 (or 68) which opens at the internal face FI58 (or FI60) and the external face FE58 (or FE60), the bore 66 (or 68) having an axis of revolution perpendicular to the internal face FI58 (or FI60) and to the external face FE58 (or FE60).
    The arm 62 comprises two lateral faces F62, F62 'parallel to each other and to the pivot axis A64 as well as a bore 70 which opens at the lateral faces F62, F62', the bore 70 having an axis of revolution perpendicular at the side faces F62, F62 '.
    The cylindrical axis 64 can be solid or hollow. It has a cylindrical peripheral face 72 coaxial with the pivot axis A64, which extends between first and second end faces 74.1, 74.2 substantially perpendicular to the pivot axis A64.
    The pivoting connection device 50 comprises at least one guide ring 76 interposed between one of the branches 58 and the cylindrical axis 64. The guide ring 76 comprises an inside diameter, equal to the outside diameter of the cylindrical axis 64, and an outside diameter equal to the inside diameter at the bore 66 of the first branch 58.
    According to one configuration, the bores 66 to 70 of the first and second branches 58, 60 and of the arm 62 include guide rings. According to one configuration, only the bores 66, 68 of the first and second branches 58, 60 comprise guide rings.
    Whatever the configuration, the first branch 58 of the yoke 56 comprises a guide ring 76, positioned in the bore 66 of said first branch 58, which comprises:
    a tubular body 78, extending between first and second ends 78.1,
    78.2, which presents:
    o a flange 80, at the first end 78.1, configured to bear against the internal face FI58 of the first branch 58, and o a section 82, at the second end 78.2, projecting relative to the external face FE58 of the first branch 58 (when the guide ring 76 is positioned in the bore 66 of the first branch 58 and the flange 80 is in abutment against the internal face FI58 of the first branch 58), an extension 84, s 'extending between first and second ends 84.1,
    84.2, projecting from the external face FE58 of the first branch 58 (when the guide ring 76 is positioned in the bore 66 of the first branch 58 and the flange 80 is in abutment against the internal face FI58 of the first branch 58), the first end 84.1 of the extension 84 being connected to the second end 78.2 of the tubular body 78, the extension 84 having at least one slot 86 allowing the extension 84 to expand radially elastically.
    The tubular body 78 and the extension 84 form only one single piece.
    According to an embodiment visible in FIGS. 9 to 11, the tubular body 78 and the extension 84 have internal diameters identical and substantially equal to the external diameter of the cylindrical axis 64. Thus, the extension 84 comprises an internal face 85 in contact with the peripheral face of the cylindrical axis 64 when the extension 84 is not radially expanded.
    The tubular body 78 has an outside diameter substantially equal to the diameter of the bore 66 of the first branch 58 and greater than that of the extension 84. The extension 84 has a small thickness promoting its elastic deformation.
    The collar 80 has a diameter greater than the outside diameter of the tubular body 78. This collar 80 makes it possible to block the guide ring 76 relative to the first branch 58 in the longitudinal direction, in a first direction.
    According to one embodiment, the extension 84 comprises several slots 86 distributed regularly over the circumference of the extension 84.
    Each slot 86 is parallel to the pivot axis A64 and extends from the second end 84.2 of the extension 84 to approximately the first end 84.1 of the extension 84.
    According to a characteristic of the invention, the pivoting connection device comprises an immobilization system 88 of the cylindrical axis 64 and of the guide ring 76 relative to each other, configured to occupy a free state, visible in FIG. 12A, in which the cylindrical axis 64 and the guide ring 76 slide relative to each other in a direction parallel to the pivot axis A64, and a locked state, visible in the figure 12B, in which the cylindrical axis 64 and the guide ring 76 are immobilized relative to each other in the longitudinal direction, in both directions.
    According to one configuration, the immobilization system 88 comprises shapes at the level of the cylindrical axis 64 and of the extension 84 of the guide ring 76 which are configured to cooperate with each other when the immobilization system is in the blocked state.
    According to one embodiment, the immobilization system 88 comprises at least one groove 90 which extends over the entire circumference of the peripheral face 72 of the cylindrical axis 64, in a transverse plane.
    In addition, the immobilization system 88 comprises at least one rib 92, at the level of the inner face 85 of the extension 84 of the guide ring 76, the shapes of which are complementary to those of the groove 90 of the cylindrical axis 64 .
    According to one configuration, the groove 90 and the rib 92 have identical trapezoidal sections and each have two flared side walls 94 (referenced in FIG. 12A) which favor the introduction or the exit of the rib 92 from the groove 90.
    The extension 84 is configured to be able to deform radially in an elastic manner, in particular thanks to the slots 86, to allow the rib 92 to slide on the cylindrical axis 64 (as illustrated in FIG. 12A) when it is not positioned to the right of the groove 90 and to enter said groove 90 (as illustrated in FIG. 12B) when the rib 92 and the groove 90 are positioned at the right of one another.
    The pivoting connection device 50 comprises a locking system 96 configured to occupy a disassembled state (visible in FIG. 13A), in which it allows mounting and sliding of the guide ring 76 in the bore 66 of the first branch 58, and a blocked state (visible in FIG. 13B) in which it is in contact with the external face FE58 of the first branch 58 in order to block the guide ring 76 relative to the first branch 58 in the longitudinal direction, in a second sense opposite to the first sense.
    Thus, the locking system 96 and the collar 80 immobilize the guide ring 76 relative to the first branch 58 in the longitudinal direction, in both directions.
    According to one embodiment, the locking system 96 comprises a thread 98, at the level of the section 82 of the guide ring 76, projecting relative to the external face FE58 of the first branch 58 and a locking nut 100 having a threaded bore 102 configured to be screwed onto the thread 98. When the locking nut 100, screwed onto the thread 98, is in contact with the external face FE58 of the first branch 58, the locking system is in the blocked state . The flange 80 being in contact with the internal face FI58 of the first branch and the locking nut 100 being in contact with the external face FE58 of the first branch 58, the guide ring 76 is immobilized in translation relative to the first branch 58 in the longitudinal direction, in both directions.
    According to another characteristic of the invention, the pivoting connection device 50 comprises a locking system 104 configured to prevent the immobilization system 88 from going from the locked state to the free state by limiting the radial expansion of the extension 84 of the guide ring 76.
    According to one embodiment, the locking system 104 comprises a locking ring 106 configured to be fitted on the extension 84 and prevent the rib 92 from coming out of the groove 90.
    According to one embodiment, this locking ring 106 has an inside diameter greater than or equal to the outside diameter of the extension 84 and less than the outside diameter of the extension 84 increased by twice the height (dimension taken in the radial direction) of the rib 92 According to one configuration, the locking ring 106 has an inside diameter substantially equal to the outside diameter of the extension 84 so that there is no radial deformation in the locked state.
    According to another embodiment, the internal surface of the release ring 106 has a slightly frustoconical shape, so as to exert a slight radial pressure on the external surface of the extension 84 when the release ring 106 is fitted which corresponds to the 'blocked state. Due to its flexibility, this pressure generates a slight deformation of the extension 84 in the direction of the cylindrical axis 64 and consequently a radial pressure between the rib 92 and the groove 90, which generates tangent friction forces preventing relative rotation. of the cylindrical axis 64 relative to the extension 84.
    According to an embodiment visible in FIGS. 7, 8, 13A and 13B, the locking nut 100 and the locking ring 106 form only one and the same part. Thus, the screwing of the locking nut 100 makes it possible to maintain the locking ring 106 fitted on the extension 84.
    According to one configuration, the pivoting connection device 50 comprises a non-rotating system preventing the locking nut 100 from unscrewing.
    The assembly of the pivoting connection device is described with reference to FIGS. 9, 10, 12A, 12B, 13A and 13B.
    Firstly, the guide ring 76 is introduced into the bore 66 of the first branch 58 from the internal face FI58, as illustrated in FIG. 9. The guide ring 76 slides in the bore 66 until that the flange 80 comes into contact against the internal face FI58 of the first branch 58, as illustrated in FIG. 10.
    Following, the cylindrical axis 64 is introduced, via the extension 84, into the guide ring 76. The shape of the rib 92 promotes the radial expansion of the extension 84 when the end face 74.1 of the cylindrical axis 64 comes into contact with said rib 92. The passage of the cylindrical axis 64 to the right of the rib 92 causes the elastic expansion of the extension 84, as illustrated in FIG. 12A. The cylindrical axis 64 is introduced into the guide ring 76 until the rib 92 cooperates with the groove 90. Due to its elasticity, the extension 84 regains its cylindrical shape, as illustrated in FIG. 12B. The immobilization system 88 is in the blocked state. Thus, the cylindrical axis 64 and the guide ring 76 are immobilized relative to each other in the longitudinal direction.
    Consequently, the locking nut 100 and the locking ring 106 are fitted onto the extension 84, as illustrated in FIG. 13A. The locking nut 100 is screwed onto the threaded section 82 of the guide ring 76 until it comes into contact with the external face FE58 of the first branch 58. The guide ring 76 is then immobilized relative to the first branch 58 in a longitudinal direction, as illustrated in FIG. 13B. The cylindrical axis 64 being immobilized relative to the guide ring 76 in the longitudinal direction, it is found immobilized relative to the first branch 58 in the longitudinal direction.
    The locking ring 106 being linked to the locking nut 100 when the latter is screwed, it is found fitted on the extension 84 and prevents any radial expansion of the latter.
    According to the invention, the pivoting connection device can be assembled from one side of the yoke 56. Thus, the outer face FE60 of the second branch 60 can be inaccessible.
    According to another advantage, the pivoting connection device does not induce any radial load in the bore of one of the branches, unlike the second embodiment of the prior art. Finally, none of the other parts of the pivoting connection device is subjected to stresses in the locked state.
