Description

Technical Field

[0001] The invention relates to a wing for an aircraft. Other aspects of the invention relate to a high lift assembly for such a wing and an elongated track for a connecting assembly of such a wing, as well as a roller bearing assembly system and a method for assembling a high lift assembly for a wing of an aircraft. Background Art

[0002] One aspect of the present invention relates to a wing for an aircraft. The wing includes a main wing and a high-lift assembly. The high-lift assembly includes a high-lift body and a connection assembly that movably connects the high-lift body to the main wing so that the high-lift body can move between a retracted position and at least one extended position.

[0003] The connection assembly includes an elongated track extending between a first end and a second end along a track longitudinal axis and having a middle portion located between the first end and the second end. The elongated track may have a curved form or a straight form along the track longitudinal axis. At least one or both of the first end and the middle portion of the elongated track are mounted to the high lift body.

[0004] The first end and / or the middle part of the track are mounted to the high lift body, and the track is mounted to the main wing via roller bearings so that the track can move along the track longitudinal axis. The front end can be an end positioned towards the expected direction of the forward movement of the wing during the flight of the aircraft. Alternatively, the first end can correspond to the rear end of the connecting assembly, for example, the end positioned away from the expected direction of the forward movement of the wing during the flight of the aircraft. In the case where the high lift body is a leading edge slat or includes a leading edge slat, the first end can correspond to the front end of the connecting assembly. In the case where the high lift body is a trailing edge flap or includes a trailing edge flap, the first end can correspond to the trailing end of the connecting assembly.

[0005] The first end of the elongated track can preferably be mounted to the leading edge slat or the trailing edge flap by any appropriate means, for example, by the arrangement of a spherical support, preferably mounted to the leading edge slat or the trailing edge flap in a fixed manner relative to the chord plane. The elongated track can be mounted to the main wing by a roller support so that the elongated track and the leading edge slat or the trailing edge flap can be moved relative to the main wing. The elongated track can be in the form of, for example, a C-shaped shape, so that its surface is positioned relative to the circumferential surface of the roller support, wherein the distance between the upper surface and the lower surface of the elongated track is greater than the diameter of the roller support, so that the roller support can only engage with one of the upper surface or the lower surface of the elongated track at any time. That is, the distance between the upper surface and the lower surface of the elongated track is selected so that a gap is provided between the roller support and the upper surface or the lower surface of the elongated track, so that the roller support cannot engage with the upper surface and the lower surface of the elongated track at the same time, thereby wedging therein.

[0006] The roller support includes at least one roller pair, the roller pair including a first roller and a second roller, each of the first roller and the second roller being mounted to at least one of the main wing and the track via a corresponding first eccentric connector assembly and a second eccentric connector assembly. Each of the first roller and the second roller may have a corresponding first axis of rotation and a second axis of rotation, and the first axis of rotation and the second axis of rotation may be coaxial. According to this aspect, the first eccentric connector assembly and the second eccentric connector assembly are configured to be simultaneously engaged by a single member for synchronous assembly of the first roller and the second roller. The first eccentric connector assembly and the second eccentric connector assembly may be configured to be simultaneously engaged by a common member for synchronous assembly of the first roller and the second roller.

[0007] Known wings for aircraft include a high lift assembly with a high lift body, which is connected to the main wing by a connecting assembly. One way of mounting the connecting assembly to the main wing is via a roller assembly. In order to properly and accurately mount the connecting assembly to the main wing, the roller assembly must be accurately assembled to provide the correct alignment of the high lift body with the wing. Although it is desirable that the manufacturing tolerance is as low as possible, the cost and time constraints of component production mean that the reduction of tolerance has a practical limit. The assembly process allows the tolerance of the components to be relaxed within the practical limit while still providing the high lift body and the wing. In the case where the roller assembly includes more than one roller, the roller must be assembled separately. This separate assembly may result in a slight misalignment between the rollers, which may cause uneven stress distribution between the rollers and / or may result in the jamming / premature degradation of the roller support. Summary of the invention

[0008] It is therefore an object of the present invention to provide an uncomplicated connection assembly which allows a plurality of rollers to be assembled precisely in a roller support.

[0009] The object is achieved in that the first connecting assembly and the second connecting assembly achieve synchronous assembly of the first roller and the second roller by simultaneous engagement of the alignment member, thereby ensuring that the first roller and the second roller are not accidentally misaligned during the assembly process. Preventing or minimizing misalignment between the first roller and the second roller can increase the life of the first roller and the second roller due to reduced stress concentration in the rollers. It can also save assembly time and the cost of assembling the support, and reduce the need to replace the support due to more evenly distributed wear.

[0010] According to one embodiment, the first eccentric connector assembly and the second eccentric connector assembly may each include a corresponding first mounting portion and a second mounting portion for coupling with at least one of the main wing and the track and a corresponding first bearing portion and a second bearing portion for coupling with the corresponding first roller and the second roller. The mounting portion may have a diameter different from the diameter of the bearing portion. The mounting portion may be coupled to the bearing portion or may be formed integrally with the bearing portion. The mounting portion may be coupled to / engaged with at least one of the main wing and the track so as to be able to rotate relative to at least one of the main wing and the track. The mounting portion may be engaged with at least one of the main wing and the track in any appropriate manner. For example, the mounting portion may be located, for example at least partially located, in an opening in at least one of the main wing and the track. The mounting portion may be held relative to at least one of the main wing and the track by a nut and a washer device, and the mounting portion may include a threaded portion so that the nut and the washer can be mounted relative to the threaded portion.

[0011] At least a portion or all of each mounting portion may be rotatable relative to at least one of the main wing and the track about the corresponding first connector rotation axis and the second connector rotation axis, and each of the first roller and the second roller may be rotatable relative to the corresponding support portion about the corresponding first roller rotation axis and the second roller rotation axis. Each of the first connector rotation axis and the second connector rotation axis may deviate from the corresponding roller rotation axis, so that the first mounting portion and the second mounting portion may achieve corresponding rotation of the corresponding roller rotation axis about the connector rotation axis and synchronous assembly of the first roller and the second roller through engagement of the alignment member and rotation about the corresponding connector rotation axis.

[0012] The first connection assembly and the second connection assembly can each include an elongated connector, a mounting sleeve (e.g., a mounting sleeve in the form of a bushing) located on the elongated connector to define a mounting portion, and a support sleeve (e.g., a support sleeve in the form of a bushing) located on the elongated connector to define a support portion. The mounting sleeve can be axially offset from the support sleeve along the elongated connector. In other words, the longitudinal axes of the mounting sleeve and the support sleeve (both of which can be generally cylindrical in shape) can be offset (e.g., not coaxial) and optionally parallel.

[0013] A section (e.g., segment) of the elongated connector defining the mounting portion may include a diameter that is different from a diameter of a section (e.g., segment) of the elongated connector defining the support portion. A section of the elongated connector defining the mounting portion may include a diameter that is larger than a diameter of a section of the elongated connector defining the support portion.

[0014] The mounting sleeve may have a diameter that is different from the diameter of the supporting sleeve (e.g., a larger diameter or a smaller diameter). Where the diameter of the mounting sleeve is different from the diameter of the supporting sleeve, the elongated connector may have a constant diameter along its length, e.g., its entire length. The thickness of the mounting sleeve may be different from the thickness of the supporting sleeve, e.g., a cross-section, such as a circumferentially extending cross-section, of one of the mounting sleeve and the supporting sleeve may be different from the cross-section of the other of the mounting sleeve and the supporting sleeve (e.g., thicker than the cross-section of the other of the mounting sleeve and the supporting sleeve). Where one sleeve is thicker or includes a thicker portion, the elongated connector may include a longitudinal axis that is offset (e.g., offset and parallel) relative to the offset sleeve having the thicker portion, such that the elongated connector is non-axially disposed relative to the sleeve and / or extends non-axially through the sleeve, and optionally coaxially disposed relative to the other sleeve or extends coaxially through the other sleeve. Each of the first connector rotation axis and the second connector rotation axis may be parallel to the corresponding roller rotation axis and radially offset from the corresponding roller rotation axis.

[0015] Each of the first eccentric connector assembly and the second eccentric connector assembly may include a corresponding first through hole and a second through hole. The first through hole may be configured to align with the second through hole so that the alignment member can be positioned in the first through hole and extend from the first through hole and extend into the second through hole. Therefore, the alignment member can be used to reconfigure both the first eccentric connector assembly and the second eccentric connector assembly synchronously and / or simultaneously. The rotation of the alignment member can cause the rotation of both the first eccentric connector assembly and the second eccentric connector assembly. The rotation of the alignment member can cause the roller rotation axis to rotate around the connector rotation axis of each of the first connection assembly and the second connection assembly. The rotation of the roller rotation axis around the connector rotation axis can achieve and / or help the assembly of the first roller and the second roller.

[0016] The alignment member may be an alignment key. The alignment key may be removed from the first eccentric connector assembly and the second eccentric connector assembly after the assembly process has been completed. The alignment key may include a handle and an elongated section for positioning in the first through hole and the second through hole. The handle may be rotatable directly by a user (e.g., by the user's hand) or by a machine that may be configured to grasp the handle.

[0017] The through hole of each or both of the first eccentric connector assembly and the second eccentric connector assembly may be concentric with the mounting portion or the support portion. The longitudinal axis of the through hole may be coaxial with the connector rotation axis or the roller axis. The longitudinal axis of the through hole may be coaxial with the mounting portion or the support portion having a smaller diameter.

[0018] The elongated rail may have an I-shaped or double-T-shaped cross-sectional shape.

[0019] One aspect relates to an elongated track for a connection assembly of a wing consistent with the previous text. Wherein the elongated track is at least one of the following: the elongated track includes a first engagement surface and a second engagement surface, the first engagement surface and the second engagement surface can be configured to engage with the corresponding first and second surfaces of the first roller and the second roller including the corresponding first and second eccentric connector assemblies; and the elongated track can be configured to mount the first and second rollers including the first and second eccentric connector assemblies to the elongated track. The elongated track defines a channel, which is used to allow an alignment member to simultaneously engage both the first and second eccentric connector assemblies so that the first and second rollers can be assembled synchronously relative to the track.

[0020] The elongate track may comprise two flanges connected by a web.The channel may be at least partially defined in or at least partially defined by the web.The alignment member may thus extend through the track.

[0021] On the other hand, a high lift assembly for a wing according to the previously described invention is disclosed. The high lift assembly comprises a high lift body and a connection assembly, which can be configured to connect the high lift body to the main wing of the aircraft in a movably manner so that the high lift body can move between a retracted position and at least one extended position. The connection assembly comprises an elongated track extending between a first end and a second end along a longitudinal axis of the track and having a middle portion between the first end and the second end. The first end and / or the middle portion of the track are mounted to the high lift body, and the track can be configured to be mounted to the main wing of the aircraft via a roller support so that the track can move along the longitudinal axis of the track. The roller support can include at least one roller pair, the roller pair comprising a first roller and a second roller, each of the first roller and the second roller being configured to be mounted to at least one of the main wing and the track via a corresponding first eccentric connector assembly and a second eccentric connector assembly. The first roller and the second roller can have a coaxial axis of rotation. The first and second eccentric connector assemblies are configured to be simultaneously engaged by a single alignment member for synchronous assembly of the first and second rollers. The first and second eccentric connector assemblies may be configured to be engaged by a common alignment member for synchronous assembly of the first and second rollers.

[0022] Another aspect relates to a roller bearing assembly system for a high lift assembly, the roller bearing assembly system including a first eccentric connector assembly and a second eccentric connector assembly, the first eccentric connector assembly and the second eccentric connector assembly being configured to mount a roller to at least one of a main wing of an aircraft and a track of a connecting assembly, wherein the first eccentric connector assembly and the second eccentric connector assembly are configured to be simultaneously engaged by a single alignment member for synchronous assembly of the first roller and the second roller. As in the previous aspect, the alignment member can be a common alignment member of the first eccentric connector assembly and the second eccentric connector assembly.

[0023] Yet another aspect relates to a method for assembling a high lift assembly of a wing of an aircraft, the method comprising: providing a wing of an aircraft as described above; simultaneously engaging an alignment member with both a first eccentric connector assembly and a second eccentric connector assembly; and synchronously rotating the first connection assembly and the second connection assembly to assemble a roller support relative to an elongated track.

[0024] One aspect relates to an aircraft comprising a wing as described above and comprising a high-lift assembly also as described above. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 The wing thickness direction 67 is also shown. Figure 1 The central connection assembly 9 is illustrated as connecting the slat 7 to the main wing 5 , but it should also be understood that the connection assembly 9 may be used to connect the trailing edge flap 2 to the wing 5 of an aircraft.

[0033] Figure 2A 1 shows a connection assembly 1006 for a wing of an aircraft according to the prior art, the connection assembly 1006 being configured to connect a high lift body 1032 (in this case a slat) to a main wing of the aircraft. The connection assembly 1006 may be used with Figure 1 The wing 3 is used in combination with a wing 3 similar to the wing depicted in the figure, wherein the wing 1 includes a main wing 5, a slat 7 and a connecting assembly 9 (the connecting assembly 9 according to the present disclosure), which connects the slat 7 to the main wing 5 in a movably manner so that the slat 7 can move between a retracted position and at least one extended position.

[0034] According to the prior art, the connection assembly 1006 includes a slat track 1017, which extends between a front end 1021 and a rear end 1023 along a track longitudinal axis 1019 and has a middle portion 1025 located between the front end 1021 and the rear end 1023. The front end 1021 of the slat track 1017 is fixedly mounted to the slat 1007. The rear end 1023 and the middle portion 1025 of the slat track 1017 are movably mounted to the main wing 5 through a roller support 1027, so that the slat track 1017 can move along the track longitudinal axis 1019. The roller support 1027 includes a guide rail 1029 fixedly mounted to the main wing 5 and a first roller unit 1031 fixedly mounted to the rear end 1023 of the slat track 1017 and engaged with the guide rail 1029. The roller support 1027 comprises a second roller unit 1033 which is fixedly mounted to the main wing 5 and engages with an engagement surface 1035 provided at the middle portion 1025 of the slat track 1017. Figure 3 5 , the slat track 1017 has a profile including an upper flange portion 1039, a lower flange portion 1041, and at least one web portion 1043 connecting the upper flange portion 1039 with the lower flange portion 1041. The second roller unit 1033 is arranged in a recess 1045 between the upper flange portion 1039 and the lower flange portion 1041 and engages with engagement surfaces 1035 provided at the upper flange portion 1039 and the lower flange portion 1041. Figure 2B A different connection assembly 2006 also known in the art is illustrated. The connection assembly 2006 includes a first roller 2031 , a second roller 2033 , and a third roller 2035 , each of which is in contact with the track 2017 .

[0035] Figure 3 According to the present disclosure and can also be used for the wings of aircraft, such as Figure 1 Transverse cross section of a connection assembly 9 in the wing described.

[0036] In this example, the connection assembly 9 connects the high lift body 12 (at Figure 3 The connecting assembly 9 includes an elongated track 16, the elongated track 16 including a track longitudinal axis, along which the track extends between a first end and a second end (with respect to Figure 2A and Figure 2B ), however, Figure 3 In the example of , the longitudinal axis of the track extends in a direction into and out of the page. Figure 3Although not shown in detail, the elongated rail 16 is connected to the high lift body at its ends or at its middle portion. The connection assembly 9 may include Figure 2A and / or Figure 2B The same features as those described in Figure 3 There may be a slat track (e.g., the elongated track 16) and a guide rail in the connection assembly. In some other examples, there may be no guide rail, and each of the rollers of the roller support (e.g., two rollers) may contact an engagement surface on the track. Therefore, it should be noted that Figure 2A and Figure 2B The connection components are merely examples of connection components, and the connection components 9 of the present disclosure may take other forms.

[0037] The elongated track 16 is mounted to the main wing via a roller support to allow movement of the track 16 along the longitudinal axis of the track. In the present example, the roller support includes at least one roller pair, the roller pair including a first roller 18 and a second roller 20. The first roller 18 rotates about a first roller rotation axis 22, and the second roller 20 rotates about a second roller rotation axis 24. The elongated track 16 includes two flange portions 34, 36 connected together by a web 38. Each of the first roller 18 and the second roller 20 is configured to engage with at least one engagement surface 40a, 40b, 42a, 42b, however in the present example, each roller 18, 20 may engage with two engagement surfaces 40a, 40b, 42a, 42b, however each roller 18, 20 may engage with only one engagement surface at any given time.

[0038] Each of the first roller 18 and the second roller 20 is mounted to a respective first eccentric connector assembly 26 and a second eccentric connector assembly 28. The first connector assembly 26 and the second connector assembly 28 may be identical or may be mirror images of each other. Each eccentric connector assembly 26, 28 includes a mounting portion 30, 32 (see Figure 4A), the mounting portions 30, 32 are configured to engage (e.g., couple) with an object to which the eccentric connector assemblies 26, 28 are mounted, which in this example is the main wing 14, however it is contemplated that the eccentric connector assemblies 26, 28 may be mounted to the track 16, in which case the flange portions 34, 36 and the engagement surfaces 40a, 40b, 42a, 42b would be located on the main wing 14. Each eccentric connector assembly 26, 28 includes a mounting sleeve 44, 46 that contacts the object to which the connector assembly 26, 28 is mounted, which in this example is the main wing 14. The mounting portions 30, 32 are generally cylindrical in shape and include a connector rotation axis 64, 66 about which the connector assembly 26, 28 or at least a portion thereof may be rotated as will be described in further detail in the following paragraphs.

[0039] Each connector assembly also includes support portions 48, 50 (see Figure 4B ), the support portions 48, 50 are configured to engage (e.g., couple to) the corresponding rollers 18, 20. Each eccentric connector assembly 26, 28 includes a support sleeve 52, 54 that contacts the rollers 18, 20 coupled thereto. In addition, each eccentric connector assembly 26, 28 includes an elongated connector 56, 58, wherein both the corresponding mounting sleeve 44, 46 and the support sleeve 52, 54 are positioned (e.g., mounted, fitted, etc.) on the elongated connector 56, 58. Positioning the sleeve 44, 46, 52, 54 between the connector 56, 58 and the item coupled thereto can facilitate rotation between the eccentric connector assembly (or at least a portion thereof) and the object to which the eccentric connector assembly is coupled, in this case the rollers 18, 20 or the main wing 14. The sleeves 44, 46, 52, 54 may rotate with the elongated connectors 56, 58, or may remain stationary while the elongated connectors 56, 58 rotate relative to the sleeves. Thus, rotation of the mounting portions 30, 32 about the connector rotation axes 64, 66 may enable rotation of the entire eccentric connector assembly 26, 28 about the connector rotation axes 64, 66 (optionally, excluding the mounting sleeves), which may enable assembly of the rollers 18, 20 of the roller support by enabling the roller rotation axes 22, 24 to move relative to the elongated track 16.

[0040] The sleeves 44 , 46 , 52 , 54 may include a low friction material to facilitate rotation of the eccentric connector assemblies 26 , 28 .

[0041] Figure 3, 50. The mounting portions 30, 32 illustrated in FIG. 5 have a smaller diameter than the diameter of the support portions 48, 50. In this example, the difference in diameter of the mounting portions 30, 32 relative to the support portions 48, 50 is caused by the difference in diameter of the elongated connectors 56, 58. However, in some examples, the elongated connectors 56, 58 may have a constant diameter along their length, and the difference in diameter may be caused by the different thicknesses of the mounting sleeves 44, 46 and the support sleeves 52, 54. For example, the mounting sleeves 44, 46 may have a thickness that is less than the thickness of the support sleeves 52, 54, so that the mounting portions 30, 32 have a smaller diameter than the diameter of the support portions 48, 50. Also in this example, the longitudinal axis of the elongated connectors 56, 58 can be offset (e.g., parallel and offset) relative to the longitudinal axis of the mounting sleeves 44, 46 (e.g., where the mounting portions 30, 32 have a larger diameter) or the support sleeves 52, 54 (e.g., where the support portions have a larger diameter) such that the connector rotation axes 64, 66 deviate from the roller rotation axes 22, 24.

[0042] Each of the connector assemblies 26, 28 (and in this example the elongated connectors 56, 58 of the connector assemblies 26, 28) includes a through hole 60, 62. The longitudinal axis of the through hole 60, 62 may be coaxial with one of the connector rotation axis 64, 66 and the roller rotation axis 22, 24.

[0043] Figure 3 Also illustrated in FIG. 6 is a channel 68 defined by the elongated track 16. In this example, the channel 68 is located in the elongated track 16 and is aligned with the longitudinal axis of the through hole.

[0044] exist Figure 4A and Figure 4B1 shows a first eccentric connection assembly 26 and a second eccentric connection assembly 28 that are simultaneously engaged by an alignment member 70, which in this example is a single (e.g., common) alignment member 70. The alignment member 70 engages with the through holes 60, 62 of the two eccentric connection assemblies 26, 28 and passes through the channel 68 defined in the elongated track 16. The alignment member 70 is in the form of an alignment key and therefore includes a handle 72 and a shaft 74. The handle is rotated to rotate the connection assemblies 26, 28 about the connector rotation axis 64, 66, which may or may not be coaxial with the longitudinal axis of the through hole and / or the alignment member 70. The alignment member 70 is used to align the longitudinal axis of the through hole and thereby also align the roller rotation axes 22, 24, and to ensure that the first eccentric connector assembly 26 rotates synchronously relative to the second eccentric connector assembly 28 by rotation of the alignment member 70. When the connection assemblies 26 , 28 are rotated about the connector rotation axes 64 , 66 by rotating the alignment member 70 , the rollers 18 , 20 may be simultaneously assembled relative to the track 16 in a precise and synchronized manner.

[0045] Figure 4B Also illustrated is a transverse cross-section of the elongated connectors 56, 58 of the connector assemblies 26, 28, illustrating the through-holes 60, 62 located in the elongated connectors 56, 58. In this example, the illustrated through-holes 60, 62 include longitudinally extending protrusions 76, 78 located in both connector assemblies 26, 28. The alignment member 70 may also include a longitudinal protrusion extending along the axis 74 of the alignment member 70 for engaging with the protrusions 76, 78 to facilitate rotation of the connector assemblies 26, 28.

[0046] Figure 5A and Figure 5B Two views of an example of an eccentric connector assembly 26, 28 are illustrated, and in particular the elongated connectors 56, 58 of the connector assemblies 26, 28 are illustrated. As can be seen, in this example, the mounting portions 30, 32 have a smaller diameter than the diameter of the support portions 48, 50. The support portions also include roller retaining means 80, which in this example is in the form of a flange having a larger diameter than the diameter of the support portion 48, although those skilled in the art will appreciate that any suitable retaining means may be used.

[0047] It should also be noted that in this example, the through holes 60, 62 may not be coaxial with either of the connector rotation axes 64, 66 or the roller rotation axes 22, 24, and in this example, the through holes 60, 62 do not include Figure 4A and Figure 4B The longitudinal protrusion in the example.

[0048] Although in the described examples the diameter of the mounting portions 30, 32 is smaller than the diameter of the bearing portions 48, 50, it should be noted that examples are equally possible where the diameter of the mounting portions 30, 32 is larger than the diameter of the bearing portions 48, 50, such as by providing the elongated connectors 56, 58 with larger diameter mounting portions 30, 32 or by providing the mounting sleeves 44, 46 with a thickness greater than the thickness of the bearing sleeves 52, 54. In all cases, rotation of the eccentric connector assemblies 26, 28 has the effect of rotating the roller rotation axes 22, 24 about the connector rotation axes 64, 66, thereby causing the rollers 18, 20 to be assembled relative to the track 14.
