Description

Technical Field

[0001] This disclosure relates to a support for mounting functional components for railway vehicles. Background Technology

[0002] Railway vehicles include bogies that run on tracks and a car body supported on the bogies. A bogie comprises a bogie frame as its skeleton. The bogie frame includes a pair of side beams and a crossbeam. To realize the function of the bogie, it also includes functional components such as brake calipers, unit brakes, motors, or gear assemblies. These functional components are mounted on supports. The supports are, for example, welded to the crossbeams. Supports joined to the crossbeams are disclosed, for example, in Patent Documents 1 and 2.

[0007] The technical problem that the invention aims to solve

[0008] Reference Figure 1 The structure of the existing support 90 will be described. Figure 1 This is a perspective view of the existing support 90. The support 90 includes a longitudinal plate member 91, a lower plate member 92, and an upper plate member 93. The longitudinal plate member 91 is welded to the lower plate member 92 and the upper plate member 93. One end of the upper plate member 93 is separated from one end of the lower plate member 92. The other end of the upper plate member 93 is welded to the other end of the lower plate member 92.

[0009] Thus, the existing support 90 is configured to combine and weld multiple plate members. However, to join the multiple plate members together, welding needs to be performed within a very narrow area. In this case, to ensure the quality of the weld, a highly skilled operator is required. However, ensuring the availability of highly skilled operators is becoming difficult, and there is a risk that the quality of the weld will be inconsistent due to the operator's skill. Inconsistent weld quality leads to a decrease in the reliability of the support.

[0010] To ensure the reliability of the support, it is also considered to use the base material of the support. However, when the entire support is made of only the base material, it tends to become heavier compared to the case where multiple plate components are joined together by welding.

[0011] The subject of this disclosure is to provide a support that can achieve lightweight design.

[0012] Technical means for solving technical problems

[0013] The support disclosed herein for mounting functional components of railway vehicles includes a first member and a second member. The first member includes a first longitudinal plate, a first lower plate, and a first upper plate. The first lower plate is connected to the lower end of the first longitudinal plate. The first upper plate is connected to the upper end of the first longitudinal plate. Viewed from the surface side of the first longitudinal plate, one end of the first upper plate and the first lower plate are separated from each other, and the other end is connected to each other. The second member includes a second longitudinal plate, a second lower plate, and a second upper plate. The second longitudinal plate is arranged opposite to the first longitudinal plate. The second lower plate is connected to the lower end of the second longitudinal plate. The second upper plate is connected to the upper end of the second longitudinal plate. Viewed from the surface side of the second longitudinal plate, one end of the second upper plate and the second lower plate are separated from each other, and the other end is connected to each other. One end of the first lower plate is connected to one end of the second lower plate. The portions of the first lower plate (excluding one end) and the portions of the second lower plate (excluding one end) are separated from each other at at least a portion. One end of the first upper plate is connected to one end of the second upper plate. The portions of the first upper plate other than one end and the portions of the second upper plate other than one end are separated from each other at at least a portion.

[0026] A support for a functional component of a railway vehicle used in an installation embodiment includes a first component and a second component. The first component includes a first longitudinal plate, a first lower plate, and a first upper plate. The first lower plate is connected to the lower end of the first longitudinal plate. The first upper plate is connected to the upper end of the first longitudinal plate. Viewed from the surface of the first longitudinal plate, one end of the first upper plate and the first lower plate are separated from each other, and the other end is connected to each other. The second component includes a second longitudinal plate, a second lower plate, and a second upper plate. The second longitudinal plate is arranged opposite to the first longitudinal plate. The second lower plate is connected to the lower end of the second longitudinal plate. The second upper plate is connected to the upper end of the second longitudinal plate. Viewed from the surface of the second longitudinal plate, one end of the second upper plate and the second lower plate are separated from each other, and the other end is connected to each other. One end of the first lower plate is connected to one end of the second lower plate. The portions of the first lower plate (excluding one end) and the portions of the second lower plate (excluding one end) are separated from each other at at least a portion. One end of the first upper plate is connected to one end of the second upper plate. The portions of the first upper plate other than one end and the portions of the second upper plate other than one end are separated from each other at at least a portion (first configuration).

[0027] The first support comprises a first member and a second member. The portions of the first member's first lower plate (excluding one end) and the second member's second lower plate (excluding one end) are separated from each other at at least a portion. That is, the first and second lower plates include portions that are separated from each other. Similarly, the portions of the first member's first upper plate (excluding one end) and the second member's second upper plate (excluding one end) are separated from each other at at least a portion. That is, the first and second upper plates include portions that are separated from each other. Therefore, compared to the case where the first and second lower plates are integrally connected, and the first and second upper plates are integrally connected, the amount of material used can be reduced. This allows for weight reduction.

[0028] Alternatively, in the first configuration of the support, the first member and the second member are separate. In this case, one end of the first lower plate may be welded to one end of the second lower plate. Furthermore, one end of the first upper plate may be welded to one end of the second upper plate (second configuration).

[0029] In the second configuration, the first component and the second component are separate. In this case, the first component and the second component can be formed separately.

[0030] In the support constructed in the first or second configuration, the lower surface of the first lower plate and the lower surface of the second lower plate can each contain a plane (the third configuration).

[0031] In any of the supports configured in the 1st to the 3rd configuration, the functional components are, for example, a brake caliper, a unit brake, a motor, or a gear mechanism (the 4th configuration).

[0032] In any of the supports configured in 1 to 4, the support may include ribs. Ribs are provided in at least one of the first longitudinal plate and the second longitudinal plate (fifth configuration).

[0033] The fifth type of support may also have the following configuration: A rib is provided on the first longitudinal plate. A bolt hole is provided on the first lower plate for fastening the functional component with bolts. When L1 is denoted as the length from one end of the first lower plate to the center of the bolt hole, the lower end of the rib provided on the first longitudinal plate is located within a range of 1 / 5 × L1 or more and 1 / 2 × L1 or less from one end of the first lower plate (sixth configuration).

[0034] The support of configuration 5 or 6 may also have the following configuration: A rib is provided on the second longitudinal plate. A bolt hole is provided on the second lower plate for fastening the functional component with bolts. When L2 is denoted as the length from one end of the second lower plate to the center of the bolt hole, the lower end of the rib provided on the second longitudinal plate is located within a range of 1 / 5 × L2 or more and 1 / 2 × L2 or less from one end of the second lower plate (configuration 7).

[0035] In any of the supports configured in 5 to 7, a rib may also be provided on the first longitudinal plate. The rib provided on the first longitudinal plate may also be connected to the first lower plate and the first upper plate (configuration 8).

[0036] In any of the supports configured in 5 to 7, the rib may also be provided on the first longitudinal plate. Alternatively, the rib provided on the first longitudinal plate may not be connected to one or both of the first lower plate and the first upper plate (configuration 9).

[0037] In any of the supports configured in 5 to 9, a rib may also be provided on the second longitudinal plate. The rib provided on the second longitudinal plate may also be connected to the second lower plate and the second upper plate (configuration 10).

[0038] In any of the supports configured in 5 to 9, the rib may also be provided on the second longitudinal plate. Alternatively, the rib provided on the second longitudinal plate may not be connected to one or both of the second lower plate and the second upper plate (configuration 11).

[0039] In any of the supports configured 1 to 11, at least one of the first longitudinal plate and the second longitudinal plate may also have a through hole (configuration 12).

[0040] In the 12th configuration of the support, at least one of the first and second longitudinal plates has a through hole. This reduces the volume of the first and / or second longitudinal plates, thus making the support lighter.

[0041] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In the drawings, the same reference numerals are used to label the same or equivalent configurations, and the same descriptions will not be repeated.

[0042] [First Embodiment]

[0043] Figure 2 and Figure 3 These are perspective and front views of the support 10 according to this embodiment. The support 10 is used to mount functional components (not shown) for railway vehicles. These functional components include, for example, brake calipers, unit brakes, motors, or gear mechanisms. Typically, the bogie frame of a railway vehicle includes a pair of side beams (not shown) and a crossbeam 80 connecting the side beams to each other. The crossbeam 80 extends along the left-right direction (width direction) of the railway vehicle. Figure 2 As shown, the support 10 is engaged with the crossbeam 80 of the bogie frame of the railway vehicle. Figure 2 Only a portion of the crossbeam 80 is shown schematically. Figure 3 The diagram shows the support 10 viewed from the side of the beam 80 along the front-rear direction.

[0044] For ease of explanation, the vertical direction of the railway vehicle with the support 10 and the crossbeam 80 engaged will be referred to as the vertical direction. Similarly, the horizontal direction of the railway vehicle with the support 10 and the crossbeam 80 engaged will be referred to as the horizontal direction, and the forward and backward direction (direction of travel) of the railway vehicle with the support 10 and the crossbeam 80 engaged will be referred to as the forward and backward direction.

[0045] Reference Figure 2 The support 10 is joined to the crossbeam 80 from one side in the front-rear direction. The joining method between the support 10 and the crossbeam 80 is, for example, welding. Figure 2 In this example, the support 10 is joined to the crossbeam 80 by a welded part W. The support 10 includes a first member 20 and a second member 30.

[0046] The first component 20 includes a longitudinal plate 21, a lower plate 22, and an upper plate 23.

[0047] With the support 10 installed on the crossbeam 80, the longitudinal plate 21 intersects the extending direction of the crossbeam 80. The longitudinal plate 21 is configured substantially along the front-rear direction. In this embodiment, the longitudinal plate 21 has a substantial thickness covering the entire area in the front-rear direction. The lower plate 22 is connected to the lower end of the longitudinal plate 21. The upper plate 23 is connected to the upper end of the longitudinal plate 21. That is, the lower plate 22 and the upper plate 23 are connected by the longitudinal plate 21 in the vertical direction.

[0048] A lower plate 22 is disposed along the lower end of a longitudinal plate 21. An upper plate 23 is disposed along the upper end of a longitudinal plate 21. Viewed from the surface side of the longitudinal plate 21, i.e., in the left-right direction, one end 22a, 23a of the upper plate 23 and the lower plate 22 are separated from each other, while the other ends 22b, 23b are connected to each other. More specifically, on the side of the crossbeam 80, the ends 22a, 23a of the lower plate 22 and the upper plate 23 are separated vertically from each other, while on the opposite side of the crossbeam 80, the ends 22b, 23b of the lower plate 22 and the upper plate 23 are close to each other. One end 22a is the end of the lower plate 22 on the crossbeam 80 side in the front-back direction, and the other end 22b is the end of the lower plate 22 on the opposite side of the crossbeam 80 in the front-back direction. Similarly, one end 23a is the end of the upper plate 23 on the crossbeam 80 side in the front-back direction, and the other end 23b is the end of the upper plate 23 on the opposite side of the crossbeam 80 in the front-back direction. Viewed from the left and right, the lower plate 22 and the upper plate 23 are roughly "U" shaped, for example. The vertical dimension of the longitudinal plate 21 is the largest on the side of the crossbeam 80, and gradually decreases as it moves away from the crossbeam 80 in the front and back direction.

[0049] The second component 30 is arranged side by side with the first component 20 in the left-right direction. The second component 30 includes a longitudinal plate 31, a lower plate 32, and an upper plate 33.

[0050] With the support 10 installed on the crossbeam 80, the longitudinal plate 31 intersects the extending direction of the crossbeam 80. The longitudinal plate 31 is configured substantially along the front-rear direction. In this embodiment, the longitudinal plate 31 has a substantial thickness covering the entire area in the front-rear direction. The longitudinal plate 31 is configured opposite to the longitudinal plate 21 of the first member 20. The longitudinal plate 31 and the longitudinal plate 21 of the first member 20 are spaced apart in the left-right direction. Therefore, a space S is formed between the longitudinal plates 21 and 31.

[0051] The lower plate 32 is connected to the lower end of the longitudinal plate 31. The upper plate 33 is connected to the upper end of the longitudinal plate 31. That is, the lower plate 32 and the upper plate 33 are connected by the longitudinal plate 31 in the vertical direction.

[0052] The lower plate 32 is disposed along the lower end of the longitudinal plate 31. The upper plate 33 is disposed along the upper end of the longitudinal plate 31. Viewed from the surface side of the longitudinal plate 31, i.e., in the left-right direction, one end 32a, 33a of the upper plate 33 and the lower plate 32 are separated from each other, while the other ends 32b, 33b are connected to each other. More specifically, on the side of the crossbeam 80, the end 32a of the lower plate 32 and the upper plate 33 ( Figure 3 The lower plate 32 and upper plate 33 are separated vertically from each other. On the opposite side of the crossbeam 80, the ends 32b and 33b of the lower plate 32 and upper plate 33 are close to each other. One end 32a is the end of the lower plate 32 on the crossbeam 80 side in the front-back direction, and the other end 32b is the end of the upper and lower plates 32 on the opposite side of the crossbeam 80 in the front-back direction. Similarly, one end 33a is the end of the upper plate 33 on the crossbeam 80 side in the front-back direction, and the other end 33b is the end of the upper plate 33 on the opposite side of the crossbeam 80 in the front-back direction. When viewed in the left-right direction, the lower plate 32 and upper plate 33 are, for example, roughly "U" shaped. The vertical dimension of the longitudinal plate 31 is largest on the side of the crossbeam 80 and gradually decreases as it moves away from the crossbeam 80 in the front-back direction.

[0053] Reference Figure 3 In the first component 20, the aforementioned end 22a of the lower plate 22 and the aforementioned end 23a of the upper plate 23 are larger in the left-right direction compared to the longitudinal plate 21. Therefore, in the front view of the support 10, the first component 20 can have a generally "I" shape. Similarly, in the second component 30, the aforementioned end 32a of the lower plate 32 and the aforementioned end 33a of the upper plate 33 are larger in the left-right direction compared to the longitudinal plate 31. Therefore, in the front view of the support 10, the second component 30 can have a generally "I" shape.

[0054] One end 22a of the lower plate 22 of the first member 20 is connected to one end 32a of the lower plate 32 of the second member 30. The portions of the lower plate 22 other than the aforementioned end 22a and the portions of the lower plate 32 other than the aforementioned end 32a are separated from each other at at least a portion. In this embodiment, the lower plates 22 and 32 are arranged spaced apart from each other in the left-right direction, covering the entire portion excluding ends 22a and 32a.

[0055] One end 23a of the upper plate 23 of the first component 20 is connected to one end 33a of the upper plate 33 of the second component 30. The portions of the upper plate 23 other than the one end 23a and the portions of the upper plate 33 other than the one end 33a are separated from each other at at least a portion. In this embodiment, the upper plates 23 and 33 are arranged spaced apart from each other in the left-right direction, covering the portions excluding ends 23a and 33a.

[0056] like Figure 3 As shown, the lower plate 22 of the first component 20 includes an upper surface 221 and a lower surface 222. The upper plate 23 includes an upper surface 231 and a lower surface 232. A longitudinal plate 21 is connected to the upper surface 221 of the lower plate 22 and the lower surface 232 of the upper plate 23. At the other end 22b of the lower plate 22 ( Figure 2 For example, an upper plate 23 is connected to the upper surface 221 of the lower plate 22.

[0057] The lower plate 32 of the second component 30 includes an upper surface 321 and a lower surface 322. The upper plate 33 includes an upper surface 331 and a lower surface 332. A longitudinal plate 31 is connected to the upper surface 321 of the lower plate 32 and the lower surface 332 of the upper plate 33. At the other end 32b of the lower plate 32 ( Figure 2 For example, an upper plate 33 is connected to the upper surface 321 of the lower plate 32.

[0058] The first component 20 and the second component 30 are manufactured, for example, by forging or casting. In this case, the first component 20 and the second component 30 are separate parts, and the first component 20 and the second component 30 are formed separately. When the first component 20 and the second component 30 are separate parts, the first component 20 may also be joined to the second component 30 by welding. That is, the end 22a of the lower plate 22 of the first component 20 may also be joined to the end 32a of the lower plate 32 of the second component 30 by welding. Furthermore, the end 23a of the upper plate 23 of the first component 20 may also be joined to the end 33a of the upper plate 33 of the second component 30 by welding.

[0059] When the first component 20 is manufactured by forging or casting, the lower plate 22 and the upper plate 23 are integrally formed with the longitudinal plate 21. That is, the lower plate 22 and the upper plate 23 are continuous with the longitudinal plate 21, and there is no joint between the lower plate 22 and the upper plate 23 and the longitudinal plate 21 as a welded part. Furthermore, when the first component 20 is manufactured by forging or casting, the lower plate 22 is also integrally formed with the upper plate 23. That is, the lower plate 22 at the end 22b on the opposite side of the crossbeam 80 (… Figure 2 ) is continuous with the upper plate 23 at the end 22b of the lower plate 22 and the end 23b of the upper plate 23 ( Figure 2 There is no joint between them that serves as a welded part.

[0060] Similarly, when the second component 30 is manufactured by forging or casting, the lower plate 32 and the upper plate 33 are integrally formed with the longitudinal plate 31. That is, the lower plate 32 and the upper plate 33 are continuous with the longitudinal plate 31, and there is no joint between the lower plate 32 and the upper plate 33 and the longitudinal plate 31 as a welded part. Furthermore, when the second component 30 is manufactured by forging or casting, the lower plate 32 is also integrally formed with the upper plate 33. That is, the lower plate 32 at the end 32b on the opposite side of the crossbeam 80 ( Figure 2 ) is continuous with the upper plate 33 at the end 32b of the lower plate 32 and the end 33b of the upper plate 33 ( Figure 2 There is no joint between them that serves as a welded part.

[0061] Figure 4 This is a bottom view of support 10. (Refer to...) Figure 4 Functional components for railway vehicles are mounted, for example, on the lower surface 222 of the lower plate 22 and the lower surface 322 of the lower plate 32. In this case, it is preferable that the lower surfaces 222 and 322 each comprise a plane. When the first component 20 and the second component 30 are manufactured by forging or casting, the lower surfaces 222 and 322, immediately after forging or casting, have draft angles in the forging direction (left-right direction) of the die. Therefore, at least the portion of the lower surfaces 222 and 322 on which the functional components are mounted is machined flat, for example, by machining.

[0062] Alternatively, at least one bolt hole BH may be provided in at least one of the lower plates 22 and 32, for fastening the functional component with a bolt. Figure 4 In the example, multiple bolt holes BH are provided in both the lower plate 22 and the lower plate 32. In each of the lower plates 22 and 32, the bolt holes BH are arranged side by side in the front-to-back direction, for example.

[0063] Alternatively, the lower plate 22 may include a curved portion 223. The curved portion 223 has a shape that is recessed inward towards the lower plate 22. Specifically, the curved portion 223 is an arc-shaped portion that is recessed inward in the left-right direction. Alternatively, the curved portion 223 may be recessed inward towards the center position of the bolt hole BH provided in the lower plate 22 in the left-right direction. In this case, when the thickness of the lower plate 22 is denoted as h1, the dimension x1 in the left-right direction from the innermost part of the curved portion 223 to the center position of the bolt hole BH may be 3.25 × h1 or less. Here, the thickness h1 means the thickness at the end 22b of the lower plate 22. As in this embodiment, when the lower plate 22 is provided with multiple bolt holes BH, the dimension x1 is the dimension in the left-right direction from the innermost part of the curved portion 223 to the center position of the bolt hole BH closest to the end 22b.

[0064] Similarly, the lower plate 32 may include a curved portion 323. The curved portion 323 has a shape that is recessed inwards towards the lower plate 32. Specifically, the curved portion 323 is an arc-shaped portion that is recessed inwards in the left-right direction. Alternatively, the curved portion 323 may be recessed inwards towards the center position of the bolt hole BH provided in the lower plate 32 in the left-right direction. In this case, when the thickness of the lower plate 32 is denoted as h2, the dimension x2 in the left-right direction from the innermost part of the curved portion 323 to the center position of the bolt hole BH may be 3.25 × h2 or less. Here, the thickness h2 means the thickness at the end 32b of the lower plate 32. As in this embodiment, when the lower plate 32 is provided with multiple bolt holes BH, the dimension x2 is the dimension in the left-right direction from the innermost part of the curved portion 323 to the center position of the bolt hole BH closest to the end 32b.

[0065] 〔Effect〕

[0066] The support 10 of this embodiment includes a first member 20 and a second member 30. The portion of the lower plate 22 of the first member 20 other than the aforementioned end 22a and the portion of the lower plate 32 of the second member 30 other than the aforementioned end 32a are separated from each other at least a portion. That is, the lower plates 22 and 32 include portions that are separated from each other. Similarly, the portion of the upper plate 23 of the first member 20 other than the aforementioned end 23a and the portion of the upper plate 33 of the second member 30 other than the aforementioned end 33a are separated from each other at least a portion. That is, the upper plates 23 and 33 include portions that are separated from each other. Therefore, compared to the case where the lower plates 22 and 32 are integrally connected throughout the front-rear direction, and the upper plates 23 and 33 are integrally connected throughout the front-rear direction, the amount of material used can be reduced. Thus, weight reduction can be achieved.

[0067] In the first component 20, the lower plate 22 and the upper plate 23 can also be integrally formed with the longitudinal plate 21, and the lower plate 22 can also be integrally formed with the upper plate 23. Furthermore, in the second component 30, the lower plate 32 and the upper plate 33 can also be integrally formed with the longitudinal plate 31, and the lower plate 32 can also be integrally formed with the upper plate 33. In this case, during the manufacture of the first component 20 and the second component 30, it is not necessary to weld multiple plate components. Therefore, the support 10 of this embodiment differs from the conventional support 90 (…). Figure 1 Compared to other methods, it reduces the amount of welding required, thus resulting in higher reliability.

[0068] The first component 20 can also be separated from the second component 30. In this case, the first component 20 and the second component 30 can be formed separately.

[0069] Preferably, the surface in the support 10 on which the functional components of the railway vehicle are mounted is flat. The functional components are, for example, mounted on the lower surface 222 of the lower plate 22 and the lower surface 322 of the lower plate 32. In this case, it is preferable that the lower surfaces 222 and 322 are respectively flat. This facilitates the mounting of the functional components on the lower surfaces 222 and 322.

[0070] In the support 10 of this embodiment, the lower plates 22 and 32 each include arc-shaped curved portions 223 and 323 that are recessed inward in the left and right directions. As a result, the volume of the lower plates 22 and 32 is reduced compared to the case where the lower plates 22 and 32 do not include the curved portions 223 and 323. Therefore, the support 10 can be made lighter.

[0073] Reference Figure 5 Rib 24 is provided on longitudinal plate 21. Rib 24 protrudes from longitudinal plate 21 in the left-right direction. Figure 5 In the example, rib 24 is positioned relative to longitudinal plate 21 on the second member 30 ( Figure 6 On the opposite side of the longitudinal plate 21. However, it is also possible that the rib 24 is provided on the side of the second member 30 relative to the longitudinal plate 21. In addition, it is also possible that the rib 24 is provided on both the side of the second member 30 and the opposite side of the second member 30 relative to the longitudinal plate 21. The rib 24 is provided integrally with the longitudinal plate 21, for example. The rib 24 may also be connected to the lower plate 22 and the upper plate 23.

[0074] When L1 is denoted as the length from the end of the lower plate 22 on the end 22a side to the center position of the bolt hole BH, the lower end 24a of the rib 24 is preferably located within a range of 1 / 5 × L1 or more and 1 / 2 × L1 or less from the end of the lower plate 22 on the end 22a side. That is, the center position of the thickness of the lower end 24a of the rib 24 is located within a range of 1 / 5 × L1 or more and 1 / 2 × L1 or less from the end of the lower plate 22 on the end 22a side. Here, the length L1 means the dimension in the front-back direction from the end of the lower surface 222 on the end 22a side to the center position of the bolt hole BH (refer to...). Figure 4As in this embodiment, when the lower plate 22 is provided with multiple bolt holes BH, the length L1 is from the lower surface 222 of the lower plate 22 ( Figure 4 The length from the end of the rib 24 on the end 22a side to the center position of the bolt hole BH on the side closest to the end 22b side. Alternatively, in the front-rear direction, the entire lower end 24a of the rib 24 may be contained within a range of 1 / 5 × L1 or more and 1 / 2 × L1 or less from the end of the lower plate 22 on the end 22a side. The rib 24 may also be provided, for example, in the longitudinal plate 21 at a position corresponding to the bolt hole BH on the side closest to the end 22a side of the lower plate 22.

[0075] Reference Figure 6 Rib 34 is provided on longitudinal plate 31. Rib 34 protrudes from longitudinal plate 31 in the left-right direction. Figure 6 In the example, rib 34 is disposed relative to longitudinal plate 31 on the first member 20 ( Figure 5 On the opposite side of the first member 20. However, it is also possible that the rib 34 is provided on the side of the first member 20 relative to the longitudinal plate 31. In addition, it is also possible that the rib 34 is provided on both the side of the first member 20 and the opposite side of the first member 20 relative to the longitudinal plate 31. The rib 34 is provided integrally with the longitudinal plate 31, for example. The rib 34 may also be connected to the lower plate 32 and the upper plate 33.

[0076] When L2 is denoted as the length from the end of the lower plate 32 on the end 32a side to the center position of the bolt hole BH, the lower end 34a of the rib 34 is preferably located within a range of 1 / 5×L2 or more and 1 / 2×L2 or less from the end of the lower plate 32 on the end 32a side. That is, the center position of the thickness of the lower end 34a of the rib 34 is located within a range of 1 / 5×L2 or more and 1 / 2×L2 or less from the end of the lower plate 32 on the end 32a side. Here, the length L2 means the dimension in the front-back direction from the end of the lower surface 322 on the end 32a side of the lower plate 32 to the center position of the bolt hole BH (refer to...). Figure 4 As in this embodiment, when the lower plate 32 is provided with multiple bolt holes BH, the length L2 is from the lower surface 322 of the lower plate 32 ( Figure 4 The length from the end of the rib 34 on the end 32a side to the center position of the bolt hole BH on the side closest to the end 32b side. Alternatively, in the front-rear direction, the entire lower end 34a of the rib 34 may be contained within a range of 1 / 5 × L2 or more and 1 / 2 × L2 or less from the end of the lower plate 32 on the end 32a side. Alternatively, the center position of the thickness of the lower end 34a of the rib 34 may substantially coincide with the center position of the bolt hole BH on the side closest to the end 32a side. The rib 34 may also be provided, for example, in the longitudinal plate 31 at a position corresponding to the bolt hole BH on the side closest to the end 32a side of the lower plate 32.

[0077] In this embodiment, rib 24 is provided on the longitudinal plate 21 such that its lower end 24a is located within a range of 1 / 5×L1 or more and 1 / 2×L1 or less from the end 22a side of the lower plate 22. Similarly, rib 34 is provided on the longitudinal plate 31 such that its lower end 34a is located within a range of 1 / 5×L2 or more and 1 / 2×L2 or less from the end 32a side of the lower plate 32. In this case, ribs 24 and 34 are easily positioned in the support 10A at locations where high stress is generated. For example, when the lower plates 22 and 32 are provided with multiple bolt holes BH, when ribs 24 and 34 are provided within the aforementioned range, ribs 24 and 34 become easily positioned in the multiple bolt holes BH at the position corresponding to the bolt hole BH closest to the end 22a and 32a side (beam 80 side). Here, the support 10A bears the load from the functional component at the location of the bolt hole BH. Therefore, the stress generated at the location of the bolt hole BH in the support 10A tends to be relatively large. Therefore, by setting the ribs 24 and 34 within the aforementioned range, the rigidity of the support 10A can be increased at the location where the stress is relatively large, and the strength of the support 10A can be ensured.

[0078] In this embodiment, rib 24 is connected to the lower plate 22 and the upper plate 23. However, it is also possible that rib 24 is not connected to one or both of the lower plate 22 and the upper plate 23. For example, it could be as follows: Figure 7 As shown, rib 24 is connected to the upper plate 23 but not to the lower plate 22. Alternatively, although the diagram is omitted, rib 24 may also be connected to the lower plate 22 but not to the upper plate 23. Furthermore, rib 24 may not be connected to either the lower plate 22 or the upper plate 23. Similarly, rib 34 may also be not connected to either the lower plate 32 or the upper plate 33.

[0079] In this embodiment, ribs 24 and 34 are provided on both longitudinal plates 21 and 31. However, ribs 24 and 34 may also be provided on only one of the longitudinal plates 21 and 31. That is, ribs 24 may be provided on longitudinal plate 21, but ribs 34 may not be provided on longitudinal plate 31. Conversely, ribs 34 may be provided on longitudinal plate 31, but ribs 24 may not be provided on longitudinal plate 21.

[0080] [Third Embodiment]

[0081] Figure 8 and Figure 9 This is a side view of the support 10B according to the third embodiment. Figure 8 This is a side view of support 10B obtained from the perspective of the first component 20. Figure 9 This is a side view of the support 10B obtained from the perspective of the second component 30. The support 10B of this embodiment is different from the support 10A of the second embodiment (…). Figure 5and Figure 6 Compared to 21, the shapes of longitudinal plates 21 and 31 are different.

[0082] Reference Figure 8 At least one through hole 211 is formed in the longitudinal plate 21. In this embodiment, two through holes 211 are formed in the longitudinal plate 21. The through holes 211 penetrate the longitudinal plate 21 along the thickness direction.

[0083] Preferably, the through hole 211 is formed in the longitudinal plate 21 at a location where the stress generated when the functional component is mounted on the support 10B to actuate the component is relatively small. For example, if the longitudinal plate 21 is provided with ribs 24, the through hole 211 may be formed at a different location in the front-rear direction than the ribs 24. Figure 8 In the example, one through hole 211 is disposed on one side in the front-rear direction relative to rib 24, and another through hole 211 is disposed on the other side in the front-rear direction relative to rib 24.

[0084] The shape of the through hole 211 can be appropriately selected. Viewed from the side of the support 10B, the through hole 211 can be circular, elliptical, polygonal, or other shapes. In the case where the longitudinal plate 21 has multiple through holes 211, as in this embodiment, these through holes 211 can have the same shape or different shapes. Furthermore, the sizes of the through holes 211 can be the same or different.

[0085] Reference Figure 9 At least one through hole 311 is formed in the longitudinal plate 31. In this embodiment, two through holes 311 are formed in the longitudinal plate 31. The through holes 311 penetrate the longitudinal plate 31 along the thickness direction.

[0086] Preferably, the through hole 311 is formed in the longitudinal plate 31 at a location where the stress generated when the functional component is mounted on the support 10B to actuate the component is relatively small. For example, if the longitudinal plate 31 is provided with ribs 34, the through hole 311 may be formed at a different location in the front-rear direction than the ribs 34. Figure 9 In the example, one through hole 311 is disposed on one side in the front-rear direction relative to rib 34, and another through hole 311 is disposed on the other side in the front-rear direction relative to rib 34.

[0087] The shape of the through hole 311 can be appropriately selected. From the side view of the support 10B, the through hole 311 can be circular, elliptical, polygonal, or other shapes. In the case where the longitudinal plate 31 has multiple through holes 311 as in this embodiment, these through holes 311 can have the same shape or different shapes. The size of the through holes 311 can also be the same or different. Furthermore, the through hole 311 can have the same shape as the through hole 211 provided in the longitudinal plate 21 (… Figure 8 The same shape can also have different shapes. The size of the through hole 311 can be the same as or different from that of the through hole 211.

[0088] In the support 10B of this embodiment, through holes 211 and 311 are formed in the longitudinal plates 21 and 31. As a result, the volume of the longitudinal plates 21 and 31 can be reduced, and thus the support 10B can be made lighter.

[0089] exist Figure 8 and Figure 9 In the example, two through holes 211 and 311 are formed in the longitudinal plates 21 and 31, respectively. However, the number of through holes formed in the longitudinal plates 21 and 31 is not limited to this. A single through hole 211 or 311 or more through holes 211 or 311 can be formed in the longitudinal plates 21 and 31.

[0090] In this embodiment, through holes 211 and 311 are formed in both longitudinal plates 21 and 31. However, through holes 211 and 311 may also be formed in only one of the longitudinal plates 21 and 31. That is, through holes 211 may be formed in longitudinal plate 21, but not in longitudinal plate 31. Conversely, through holes 311 may be formed in longitudinal plate 31, but not in longitudinal plate 21.

[0091] In this embodiment, ribs 24 and 34 are provided on both longitudinal plates 21 and 31. However, it is also possible that ribs 24 and 34 are not provided on one or both of the longitudinal plates 21 and 31.

[0092] The embodiments of this disclosure have been described above, but this disclosure is not limited to the above embodiments. Various modifications can be made as long as they do not depart from its spirit.

[0093] In the examples of the above embodiments, the first component 20 and the second component 30 are separate. However, it is also possible that the first component 20 is integrally provided with the second component 30. In this case, the first component 20 and the second component 30 are continuous, and there is no joint between the first component 20 and the second component 30 as a welded part. Such a first component 20 and second component 30 can be manufactured, for example, by a 3D printer or a lamination process. In this case, the amount of welding can be reduced compared to the examples of the above embodiments.

[0094] In the examples of the above embodiments, the lower plate 22 of the first member 20 is connected to the end 32a of the lower plate 32 of the second member 30 at the end 22a on the side of the crossbeam 80. The lower plate 22 and the lower plate 32 are separate from each other in the portions other than the ends 22a and 32a. However, it is also possible that the lower plate 22 and the lower plate 32 are connected at a portion other than the ends 22a and 32a. Figure 10 This is a perspective view of the modified support 10. Figure 10 In the example, the lower plate 22 is also connected to the end 32b of the lower plate 32 at the end 22b opposite to the end 22a. Alternatively, similarly to the lower plates 22 and 32, the upper plate 23 of the first member 20 and the upper plate 33 of the second member 30 may be connected at a portion other than the ends 23a and 33a.

[0095] In the examples of the above embodiments, the thickness of the longitudinal plates 21 and 31 is constant throughout the entire region in the front-back direction. However, the thickness of the longitudinal plates 21 and 31 can also vary throughout the front-back direction. For example, when the lower plate 22 is provided with bolt holes BH, in the front-back direction, at least a portion of the longitudinal plates 21 within a range of 1 / 5×L1 or more and 1 / 2×L1 or less from the end 22a side of the lower plate 22 may have a greater thickness than the longitudinal plates 21 at other locations. Similarly, when the lower plate 32 is provided with bolt holes BH, in the front-back direction, at least a portion of the longitudinal plates 31 within a range of 1 / 5×L2 or more and 1 / 2×L2 or less from the end 32a side of the lower plate 32 may have a greater thickness than the longitudinal plates 31 at other locations.
