[0032] Hereinafter, an oil passage device according to an embodiment of the technology disclosed herein will be described with reference to the drawings.

[0033] In the following, for the sake of convenience, three mutually orthogonal axes are set as the X-axis, the Y-axis, and the Z-axis. As an example, the XY plane including the X-axis and the Y-axis is horizontal, and the Z-axis is vertical. For example, the X-axis direction is the width direction of the oil circuit device 100 described later. The Y-axis direction is the depth direction of the oil circuit device 100. The Z-direction is the height direction of the oil circuit device 100.

[0034] In addition, the Z-axis direction is the "axis M direction". The "axis M direction" is a general term for one direction and another direction of an imaginary axis that is orthogonal to the bottom surface 51 of the filter device 50 described later and passes through the center of the filter device 50. The radial direction centered on the axis M is called the "radial direction", and the circumferential direction centered on the axis M is called the "circumferential direction C".

[0035] Furthermore, the positive side in the Z-axis direction corresponds to “one side in the axis M direction”, and the negative side in the Z-axis direction corresponds to “the other side in the axis M direction”.

[0036] In this specification, the vertical direction, horizontal direction, upper side, and lower side are terms used only to describe the relative positional relationship of each part. Therefore, the actual positional relationship of each part may be different from the positional relationship indicated by these terms.

[0037] [First embodiment]

[0038] (structure)

[0039] Reference Figure 1 to Figure 3 , the structure of the oil circuit device of the hydraulically operated transmission according to the first embodiment of the technology disclosed in the present invention will be described. Figure 1 It is a schematic side view showing an oil passage device of a hydraulically operated transmission according to a first embodiment. Figure 2 It is a cross-sectional view of a region including a filter device of the oil passage device according to the first embodiment. Figure 3 It is a perspective view of the filter device according to the first embodiment.

[0040] The details will be described later. The first body 10 and the second body 30 are flat, and the partition plate 20 is plate-shaped. The first body 10, the partition plate 20, and the second body 30 are stacked. From the second body 30, the direction in which the partition plate 20 and the first body 10 are stacked is the height direction, that is, the direction of the positive side of the Z axis. The thickness directions of the first body 10, the partition plate 20, and the second body 30 are the same direction, which is the height direction.

[0041] The filter device 50 is formed in a cylindrical shape with its axis M (see also Figure 3 ) direction is the Z-axis direction as described above. The thickness direction of the filter device 50 is the Z-axis direction (height direction).

[0042] like Figure 1As shown, the oil circuit device 100 controls the generation and supply of the fastening oil pressure to the plurality of friction fastening elements constituting the speed change mechanism, discharge, supply of lubricating oil to various parts in the transmission case (not shown), etc. The oil circuit device 100 is also a valve body. The oil circuit device 100 is mounted on the transmission case.

[0043] The oil passage device 100 includes a first body 10, a partition plate 20, and a second body 30. The first body 10 and the second body 30 are metal parts having a flat shape. The first body 10 and the second body 30 are, for example, die-cast products using aluminum or an aluminum alloy. The partition plate 20 has a plate-like shape and is made of, for example, a metal such as iron.

[0044] like Figure 2 As shown, the first body 10 includes: a first plane 12 having a groove-shaped first oil passage 18 ; and a second plane 14 which becomes the back side of the first plane 12 .

[0045] The partition plate 20 includes a first main surface 22 in contact with the first plane 12 and a second main surface 24 which is a rear surface with respect to the first main surface 22 .

[0046] The second body 30 has a groove-shaped second oil passage 36 on a third plane 32 in contact with the second main surface 24 of the partition plate 20 , and has a fourth plane 34 which is a back surface with respect to the third plane 32 .

[0047] The length in the thickness direction from the first plane 12 to the second plane 14 is longer than the length in the thickness direction of the second body 30. The thickness direction is the Z-axis direction.

[0048] The oil passage device 100 includes a filter device 50 in the first oil passage 18 .

[0049] The first body 10 includes a through hole 15 that reaches the first oil passage 18 in the thickness direction from the second plane 14 side of the first body 10. The through hole 15 is a hole for mounting the filter device 50.

[0050] The length of the second body 30 of the filter device 50 in the thickness direction (ie, the Z-axis direction) is longer than the length of the second body 30 in the thickness direction (ie, the Z-axis direction) from the third plane 32 to the fourth plane 34 .

[0051] Reference Figure 3 , the filter device 50 will be described in further detail.

[0052] The filter device 50 includes a portion 50U located in the through-hole 15. The filter device 50 is formed in a cylindrical shape, and includes an opening 50H on the through-hole 15 side and a bottom plate 51 on the second body 30 side.

[0053] As described above, the length of the second body 30 of the filter device 50 in the thickness direction (i.e., the Z-axis direction) is longer than the length of the second body 30 in the thickness direction (i.e., the Z-axis direction) from the third plane 32 to the fourth plane 34. Therefore, the filter device 50 is not accommodated between the third plane 32 and the fourth plane 34 of the second body 30. In the first embodiment, the side end of the second body 30 of the filter device 50 is located on the first main surface 22 of the partition plate 20 (see also Figure 2 ).

[0054] The filter device 50 includes a plurality of (eg, four) columnar portions 53 and a mesh portion 54 attached to the side surface between a portion 50U located in the through hole 15 and the bottom portion 51 .

[0055] The filter device 50 is made of, for example, a resin material except for the mesh portion 54. The mesh portion 54 is made of, for example, a nylon mesh or a stainless steel mesh.

[0056] Each columnar portion 53 of the filter device 50 has protrusions 53p1 to 53p4 protruding radially outward on the upper end side. The four protrusions 53p1 to 53p4 include: two protrusions 53p1 and 53p3 located on a first line L1 on a horizontal plane orthogonal to the central axis M of the filter device 50; and two protrusions 53p2 and 53p4 located on a second line L2 orthogonal to the first line L1 on a horizontal plane passing through the central axis M of the filter device 50. The first line L1 and the second line L2 are orthogonal to each other at a point C where the central axis M of the filter device 50 intersects the above-mentioned horizontal plane. The first line L1 is parallel to the X-axis direction, and the second line L2 is parallel to the Y-axis direction.

[0057] The distance between the two protrusions 53p2 and 53p4 and the distance between the two protrusions 53p2 and 53p4 are respectively the same and larger than the inner diameter of the through hole 15 where the protrusions 53p1 to 53p4 are located.

[0058] Therefore, when the filter device 50 is inserted into the first body 10 through the through hole 15 of the first body 10 from the bottom plate 51 side, the protrusions 53p1 to 53p4 are pressed into the through hole 15.

[0059] After the hydraulic oil is guided to the opening 50H, it passes through the mesh portion 54 and flows into the first oil passage 18. Therefore, in the oil passage device 1 of this embodiment, foreign matter in the hydraulic oil introduced into the filter device 50 is captured by the mesh portion 54, and the hydraulic oil from which the foreign matter is removed flows in the first oil passage 18.

[0060] (Effect)

[0061] Thus, in the first embodiment, the first body has a through hole extending from the second plane side of the first body to the first oil path in the thickness direction, and the filter device has a portion located in the through hole. Therefore, the oil path device of the first embodiment can have a filter device whose thickness direction is longer than the thickness direction of the second body.

[0062] [Second embodiment]

[0063] (structure)

[0064] The structure of the oil circuit device of the hydraulically operated transmission according to the second embodiment of the technology disclosed in the present invention will be described below. The structure of the oil circuit device of the second embodiment has the same parts as the oil circuit device of the first embodiment, so the same parts are marked with the same figure numbers and their descriptions are omitted, and the different parts are described.

[0065] Figure 4 FIG. 2 is a cross-sectional view of a region including the filter device 50 of the oil passage device 200 according to the second embodiment. Figure 4 As shown, in the oil passage device 200 of the second embodiment, the partition plate 20 has an insertion hole 25 for the filter device 50. The filter device 50 is inserted into the insertion hole 25. The second body 30 side end of the filter device 50 is located in the second oil passage 36.

[0066] When the filter device 50 is inserted into the first body 10 from the bottom plate 51 side through the through hole 15 of the first body 10, the protrusions 53p1 to 53p4 are located in the first oil passage 18, and the portion 50U is pressed into the through hole 15 and is fitted in a snap-fit ​​manner. The portion 50U is the portion pressed into the through hole 15.

[0067] (Effect)

[0068] Thus, in the second embodiment, the first body has a through hole extending from the second plane side of the first body to the first oil path in the thickness direction, and the filter device has a portion located in the through hole. The filter device is inserted into the insertion hole of the partition plate, and the second body side end of the filter device is located in the second oil path. Therefore, the oil path device of the second embodiment can have a filter device whose length in the thickness direction is longer than the length in the thickness direction of the second body.
