Description
Technical Field
The present invention relates to an improvement of a vehicle-mounted air cleaner device.
Background
For example, in practical use, an on-vehicle air cleaner device mounted in a motorcycle includes an element for dividing a space inside a housing main body into an unclean side and a clean side, and the element is detachable. For example, the vehicle-mounted air cleaner device disclosed in patent document 1 is considered as a vehicle-mounted air cleaner device having this structure.
In the vehicle-mounted air cleaner device disclosed in patent document 1, a funnel extending in the vertical direction is formed at the bottom of the housing main body, and a fitting frame is formed around the funnel. A cylindrical member (filter) is fitted to the outer circumference of the fitting frame from above. The opening is formed at a position facing the bottom of the housing main body. From which opening the element is inserted.
The element inserted into the opening is held by the cover member. After the cover member covers the opening, the cover member is attached to the housing main body. If the tightening member is a screw and/or a bolt, the number of constituent parts of the in-vehicle air cleaner device, i.e., the number of parts, increases because the screw and the bolt are separate members.
Further, the cover member contacts one end portion of the cylindrical element. Since there is no space between one end of the element and the cover member, the capacity of the air cleaner is limited.
Although it is required to reduce the number of components and increase the capacity of the vehicle-mounted air cleaner device, it is necessary to provide a vehicle-mounted air cleaner device that satisfies the requirement.

THE ADVANTAGES OF THE PRESENT INVENTION
In the invention according to claim 1, the connection pipe includes a connection pipe flange extending in a radial direction, and the element includes an element flange extending from the element base along the connection pipe flange. A cylindrical portion surrounding the connection pipe and an element holder configured to engage with the element flange are formed in a wall of the housing main body. The connecting pipe flange contacts the element flange or the element base on one side surface and contacts the inner end portion of the cylindrical portion on the other side surface. In this state, since the element flange is engaged with the element holder of the inner wall of the case main body, the connection pipe flange can be supported as well. Further, since the connecting pipe flange is supported by holding the connecting pipe flange between the cylinder part and the element, it is possible to support the connecting pipe and the element without using any additional fixing member. Therefore, the number of parts can be reduced.
In the invention according to claim 2, the space surrounded by the connecting pipe flange, the outer end portion of the cylindrical portion, the outer surface of the connecting pipe, and the inner surface of the cylindrical portion is a gas-liquid separation chamber configured to separate blow-by gas from the internal combustion engine into gas and liquid. Therefore, the number of parts can be reduced, and the structure can be simplified. Further, since the seal is provided for the outer surface of the connection pipe, it is possible to achieve desired airtightness, and the gas-liquid separation chamber is formed only by the connection pipe and the housing main body. Therefore, the number of parts can be reduced.
In the invention according to claim 3, the maintenance opening is formed in a wall of the housing main body that faces the element. Since the predetermined space is formed between the maintenance opening and the element, the capacity of the unclean side of the air cleaner can be increased.
In the invention according to claim 4, the housing main body is constituted by a housing member to which the element is attached and a cover member which is a member separate from the housing member. Since the cover member is welded to the case member, a connecting member is not required, and the number of parts can be reduced and airtightness can be improved.
In the invention according to claim 5, since the filter has a cylindrical shape and the element is attached by rotating the element flange to engage with the element holder, a connecting member is not required and the number of parts can be reduced. Since the flange is rotated to be tightly engaged with the element holder, airtightness can be improved.
In the invention according to claim 6, the cover member and the housing main body are connected by a hinge. The cover member is integrally formed with the housing main body. Therefore, it is not necessary to provide the hinge as a separate component, and the number of components is reduced. Further, since the lid member is opened/closed by being engaged with the engaging part provided for the housing main body, there is no need to provide the engaging part as a separate part, and the number of parts can be reduced.
In the invention according to claim 7, the cover member configured to cover the maintenance opening is provided as a member separate from the housing main body. Since the cover member is fitted to the maintenance opening, a connecting member is not required, and the number of parts can be reduced.
In the invention according to claim 8, the connection pipe is made of an elastic material. Since the connection pipe is made of an elastic material, the element flange can be biased toward and supported by the element holder of the case main body by utilizing the elasticity of the connection pipe. Therefore, the number of parts can be reduced.
In the invention according to claim 9, the connection pipe has a seal lip at a position upstream of the flange of the connection pipe. Since the seal lip contacts the cylindrical inner circumferential surface of the element base, an improvement in sealing performance is achieved. Further, since there is no need to provide any additional sealing lip, the number of parts can be reduced.

Further, the vehicle-mounted air cleaner device 60 includes an intake duct 61 for guiding outside air into the vehicle-mounted air cleaner device 60.
Then, the in-vehicle air cleaner device 60 will be described.
As shown in fig. 2, the in-vehicle air cleaner device 60 includes an air cleaner 80 and a connection pipe 110. The air cleaner 80 includes an element 70 for dividing the inner space of the housing main body 81 into an unclean side S1 and a clean side S2. The connection pipe 110 extends from the air cleaner 80 toward the intake passage of the internal combustion engine 16 (see fig. 1).
As shown in fig. 3, the in-vehicle air cleaner device 60 may be divided into an element 70, an air cleaner 80, and a connection pipe 110.
The element 70 includes a filter 71 for removing dust and an element base 72 attached to the filter 71. The element base 72 includes a first base 73 positioned at a side opposite to the connection pipe 110 and a second base 74 positioned at a side closer to the connection pipe 110 and connected to the first base 73.
The filter 71 is in the form of pleated pleats, similar to a bellows. The filter 71 has a cylindrical shape as a whole. The first base 73 includes a disc 73a supporting one end of the filter 71 and an inner circumferential support 73b extending from the disc 73a toward the second base 74 to support the inner circumference of the filter 71. Meshes or holes are formed in the inner circumferential support 73b to allow air to pass through the inner circumferential support 73 b. It should be noted that the inner circumferential support 73b may be formed by arranging cylindrical members at the same interval. The inner circumferential supporter 73b may have any structure as long as air passes through the inner circumferential supporter 73 b.
An element flange 75 extending in the radial direction is formed at the second base 74. An outer circumferential bracket 76 for supporting the outer circumference of the filter 71 is provided at one side of the element flange 75, and a positioning member 77 fitted to the housing main body 81 is provided at the other side of the element flange 75. The other end of the filter 71 is supported by an element flange 75.
The housing main body 81 of the air cleaner 80 includes a housing member 82 and a cover member 83, the element 70 is attached to the housing member 82, and the cover member 83 is provided as a separate member from the housing member 82. The wall 82a of the case member 82 has an element holder 84 engaged with the element flange 75 and a cylindrical portion 85 formed around the connection pipe 110.
An outwardly projecting protrusion 82b is formed in the housing member 82. The protruding portion 82b includes a cylindrical portion 85. Since the protruding portion 82b is connected to an intermediate position outside the cylindrical portion 85, a substantially annular space S3 is formed between the cylindrical portion 85 and the protruding portion 82b inside the housing main body 81.
A connection opening 86 is formed in the cylindrical portion 85. The connection opening 86 opens to the inside of the housing main body 81. The connection pipe 110 has a connection pipe flange 111 extending in a radial direction. The connection pipe 110 is inserted into the connection opening 86 from the inside of the housing main body 81, and the connection pipe flange 111 contacts the inner end portion 87 of the cylindrical portion 85.
A seal 113 that holds the outer end 88 of the cylindrical portion 85 is provided for the wall 112 of the connecting pipe 110 at a position downstream of the connecting pipe flange 111. The connection pipe 110 is made of an elastic material. Seal 113 is bent and fitted to outer end 88. Structurally, an improvement in the sealing performance of the seal 113 is achieved.
Further, a case-side fitting part 89 is formed in the case member 82, and a cover-side fitting part 91 is formed in the cover member 83. The cover-side fitting part 91 is fitted to the case-side fitting part 89.
The housing member 82 has a connection part 92 to the leaking hose 62. Specifically, the connection member 92 extends from a gas-liquid separation chamber 120 described later. The blow-by hose 62 guides blow-by gas from the internal combustion engine 16 (see fig. 1). The connecting member 92 has a cylindrical shape. An inlet port 93 is formed at a portion of the connection member 92 connected to the blow-by hose 62, and an outlet port 94 is formed in the wall 82a of the housing member 82. Specifically, the discharge port 94 is formed in the cylindrical portion 85.
As shown in fig. 3 and 4, a separate return member 92a for preventing the air leakage hose 62 is formed adjacent to the inlet port 93 of the connection member 92. Further, a stepped wall 95 is formed in the wall 82a of the housing member 82 at a position closer to the inlet port 93 than the outlet port 94. By the stepped wall 95, the insertion amount of the air leakage hose 62 when the air leakage hose 62 is connected to the connection member 92 can be defined.
As shown in fig. 5, the cover-side fitting member 91 is welded to the case-side fitting member 89. Since the cover-side fitting part 91 is welded to the case-side fitting part 89, a connecting member is not required, and the number of parts can be reduced. Further, by welding the cover-side fitting member 91 to the case-side fitting member 89, improvement of airtightness in the case main body 81 is achieved.
An intake port 96 for connecting the intake duct 61 (see fig. 1) is formed in the cover member 83. The outside air is introduced into the housing main body 81 from the intake port 96. The recess 97 is formed in the wall 83a of the cover member 83. The recess 97 is recessed inward. The service opening 98 opens in the recess 97 for insertion of the element 70.
The cover member 102 is provided for the cover member 83. The cover member 102 is opened/closed by the hinge 101. The maintenance opening 98 is covered by a cover member 102. An engagement part 103 for engaging with the cover member 102 is provided in the cover member 83 outside the maintenance opening 98.
The cover member 102 is integrally formed with the cover member 83. Therefore, it is not necessary to provide the hinge as a separate component, and the number of components is reduced. Further, since the lid member 102 is opened/closed by engaging with the engaging part 103 provided for the cover member 83, there is no need to provide the engaging part 103 as a separate part, and the number of parts can be reduced.
In this embodiment, the cover member 102 is integrally formed with the cover member 83. However, the present invention is not limited thereto. For example, the cover member 102 may be provided as a separate member from the cover member 83, and the cover member 102 may be provided for the cover member 83 so that the cover member 83 is opened/closed by a hinge. Further, the cover member 102 may be provided as a separate member from the cover member 83, and the cover member 102 may be fitted to the maintenance opening 98, or the cover member 102 may be fitted to the engaging part 103. Specifically, the threaded portions may be provided for the cover member 102 and the service opening 98 and fit together. In this case, the connecting member is not required, and the number of parts can be reduced.
Further, the connection pipe 110 is assembled with the housing main body 81, and the connection pipe flange 111 contacts the inner end portion 87 of the cylindrical portion 85. The outer end 88 of the cylindrical portion 88 is held by a seal 113. The cover member 102 is opened. The element 70 is inserted into the housing main body 81 through the maintenance opening 98, and the positioning member 77 is fitted into the space S3. The connection pipe flange 111 extends beyond the cylindrical portion 85 in the outer diameter direction. A gap is formed between the base end of the projection 82b and the connection pipe flange 111. The positioning member 77 is inserted into the gap.
As shown in fig. 6, a flange claw portion 78 protruding in the radial direction is formed in the element flange 75. The element 70 moves as indicated by the arrow (1), and the element flange 75 comes into contact with the wall 82a of the case member 82 so that the flange claw portion 78 does not overlap the element holder 84.
The element 70 is rotated as shown by an arrow (2), and the flange claw portions 78 are slid to the inside of the element holders 84 each having an L-shaped cross section. At a position adjacent to the element holder 84, the case member 82 includes a stopper 84 a. When the flange claw portion 78 contacts the stopper 84a, the flange claw portion 78 is stopped. In this manner, the element 70 is attached to the element bracket 84 by rotating the element flange 75. Therefore, there is no need to provide any additional connecting member to connect the element 70 to the case member 82, so that the number of parts can be reduced. Further, since the component flange 75 is rotated to be tightly engaged with the component holder 84, improvement of airtightness is achieved.
It should be noted that the flange claw portion 78 may include an inclined portion to increase the sealing property to a greater extent when the flange claw portion 78 is slid to the inside of the element holder 84. Further, a small protrusion may be provided at the entrance of the element holder 84, and the flange claw 78 may be slid to the inside of the element holder 84 so that the flange claw 78 moves beyond the protrusion. In this case, in the case where the protruding portion is present, the flange claw portion 78 can be prevented from being easily detached.
Then, the state of the assembly member will be described.
As shown in fig. 2, the connection pipe flange 111 contacts the element flange 75 on one side surface 111a, and contacts the inner end portion 87 of the cylindrical portion 87 on the other side surface 111 b. In this state, since the element flange 75 is engaged with the element holder 84, the connection pipe flange 111 can be supported at the same time. Further, since the connecting pipe flange 111 is supported by holding the connecting pipe flange 111 between the cylinder part 85 and the element 70, it is possible to support the connecting pipe 110 and the element 70 without using any additional fixing member. Therefore, the number of parts can be reduced.
Further, since the connection pipe 110 is made of an elastic material, the element flange 75 can be biased toward the element holder 84 and supported by the element holder 84 by utilizing the elasticity of the connection pipe flange 111. Therefore, the number of parts can be reduced.
Further, a space surrounded by the wall 112 of the connecting pipe 110, the connecting pipe flange 111, the cylindrical portion 85, and the outer end 88 of the cylindrical portion 85 is a gas-liquid separation chamber 120. The gas-liquid separation chamber 120 can be formed by bringing the inner end portion 87 of the cylindrical portion 85 into contact with the other side surface 111b of the connecting pipe flange 111, covering the connecting opening 86 with the connecting pipe flange 111, and bringing the outer end portion 88 of the cylindrical portion 85 into contact with the wall 112 of the connecting pipe 110.
As described above, since the gas-liquid separation chamber 120 for separating the blow-by gas from the internal combustion engine 16 (see fig. 1) into the gas and the liquid is formed in the air cleaner 80, it is not necessary to provide any additional component to form the gas-liquid separation chamber 120. Therefore, even if the gas-liquid separation chamber 120 is formed in the air cleaner 80, the number of components can be reduced. Further, the structure of the housing main body 81 can be obtained only by bringing the inner end portion 87 of the cylindrical portion 85 into contact with the side surface of the connecting pipe flange 111, and bringing the outer end portion 88 of the cylindrical portion 85 into contact with the wall 112 of the connecting pipe 110.
The connecting pipe flange 111 is in contact with the inner end 87 of the cylindrical portion 85 on one side, and the outer end 88 of the cylindrical portion 85 is held by a seal 113 on the other side to achieve the desired airtightness. The gas-liquid separation chamber 120 may be formed only by the connection pipe 110 and the housing main body 81.
Further, a connection hole 114 connected to the gas-liquid separation chamber 120 is formed in the wall 112 of the connection pipe 110 at a position downstream of the connection pipe flange 111 in a region facing the gas-liquid separation chamber 120. The connection hole 114 and the outlet port 94 of the connection member 92 are oppositely disposed on both sides of the connection pipe 110.
Since the discharge port 94 of the blowby gas in the gas-liquid separation chamber 120 is located away from the connection hole 114 for guiding the gas after the gas and liquid are separated, the gas-liquid separation is facilitated. Further, by providing the connection hole 114 at an upper position, the volume of the separated liquid stored in the gas-liquid separation chamber 120 can be increased. Further, since the connection between the gas-liquid separation chamber 120 and the clean side S2 can be simply performed by providing the connection hole 114 in the wall 112 of the connection pipe 110, there is no need to provide any member to connect the gas-liquid separation chamber 120 and the clean side S2. Therefore, the number of parts can be reduced, and the structure can be simplified.
In this embodiment, one side surface 111a contacts the element flange 75. However, the present invention is not limited thereto. One side surface 111a may contact the element base 72.
Further, a maintenance opening 98 is formed in the wall 83a facing the element 70. The predetermined space S4 is formed between the cover member 102 covering the maintenance opening 98 and the element 70. Therefore, the capacity of the unclean side S1 of the air cleaner 80 can be increased.
Further, the connection pipe 110 has a seal lip 115 at a position upstream of the connection pipe flange 111. Since the seal lip 115 contacts the cylindrical inner circumferential surface of the element base 72, an improvement in sealing performance is achieved. Further, since there is no need to provide any additional sealing lip, the number of parts can be reduced.
Then, the components of the entire apparatus are briefly described below.
As shown in fig. 7, the in-vehicle air cleaner device 60 includes an intake duct 61, an air cleaner 80, and a connection pipe 110. The air cleaner 80 includes a housing main body 81 and the element 70, and the housing main body 81 includes a housing member 82 and a cover member 83. The maintenance opening 98 and the annular engaging member 103 are formed in the recess 97 of the housing main body 81. The cover member 102 is provided for the housing main body 81 through the hinge 101. An annular portion 104 configured to be fitted to the engaging part 103 is formed in the cover member 102.
The cover member 83 is welded to the case member 82. The connection pipe 110 is assembled from the inside of the housing main body 81. The element 70 is assembled to the housing main body 81 by opening the cover member 102 and inserting the element 70 from the maintenance opening 98.
Next, the operation of the above-described in-vehicle air cleaner device 60 will be described.
In fig. 8, the outside air flows from the intake port 96 to the unclean side S1 as indicated by an arrow (3). Air from the dirty side S1 passes through the element 70 as shown by arrow (4) and flows into the clean side S2. The air of the clean side S2 flows into the connecting pipe 110 as indicated by an arrow (5), and the air is supplied to the internal combustion engine 16 (see fig. 1).
Further, the blowby gas from the internal combustion engine 16 flows from the blowby gas hose 62 to the gas-liquid separation chamber 120 as indicated by an arrow (6). The blow-by gas in the gas-liquid separation chamber 120 is separated into gas and liquid. On the one hand, the separated gas flows in a direction away from the discharge port 94 as indicated by an arrow (7) and flows from the connection hole 114 to the connection pipe 110 as indicated by an arrow (8). On the other hand, the separated liquid flows from the discharge port 94 into the blowby gas hose 62 as indicated by an arrow (9), and the liquid is supplied to the crankcase 51 of the internal combustion engine 16 (see fig. 1).
Example 2
Next, embodiment 2 of the present invention will be described with reference to the drawings. The constituent elements that are structurally the same as those shown in fig. 2 are identified by the same reference numerals, and detailed description thereof is omitted.
As shown in fig. 9 and 10, the gas-liquid separation chamber 120 is a space surrounded by the wall 112 of the connection pipe 110, the connection pipe flange 111, the cylindrical portion 85, and the outer end 88 of the cylindrical portion 85. The first connection hole 121 is formed at a position of the connection pipe flange 111 facing the gas-liquid separation chamber 120. The first connection hole 121 connects one side surface 111a to the other side surface 111b of the connection pipe flange 111.
The connecting hole extension 122 is assembled to the element base 72 at a position of the second base 74 facing the clean side S2. In this state, the connection hole extension 122 is formed to extend from the clean side S2 to the gas-liquid separation chamber 120. A second connection hole 123 is formed in the connection hole extension 122. The second connection hole 123 connects the clean side S2 and the gas-liquid separation chamber 120. That is, the second connection hole 123 is formed at a position facing the clean side S2 of the element base 72. Further, the diameter of the first connection hole 121 is larger than that of the second connection hole 123. The first connection hole 121 has a size sufficient to insert the connection hole extension 122 into the first connection hole 121.
The first connection hole 121 is connected to the second connection hole 123 by inserting the connection hole extension 122 into the first connection hole 121. As described above, since the gas-liquid separation chamber 120 and the clean side S2 are connected by connecting the first connection hole 121 and the second connection hole 123, there is no need to provide any additional connection member. Therefore, the number of parts can be reduced. Further, the gas-liquid separation chamber 120 is directly connected to the clean side S2 by inserting the connection hole extension 122 from the gas-liquid separation chamber 120 to the clean side S2. Thus, an improvement in airtightness is achieved.
Further, a protruding wall 124 is formed at the outer end 88 of the cylindrical portion 85. The projecting wall 124 projects into the gas-liquid separation chamber 120. The projecting wall 124 is disposed to face the outlet port 94. Since a so-called labyrinth structure is formed inside the gas-liquid separation chamber 120 by the protruding wall 124, gas-liquid separation of the blow-by gas is facilitated. Further, since the protruding wall 124 is integrally formed with the outer end 88 of the cylindrical portion 85, i.e., the housing main body 81, there is no need to provide any additional member. Therefore, the number of parts can be reduced. Further, after the gas is separated in the gas-liquid separation chamber 120, the gas flows into the connection pipe 110 from the second connection hole 123. The internally separated liquid flows from the drain port 94 into the blowby hose 62, and then the liquid is supplied to the crankcase 51 of the internal combustion engine 16 (see fig. 1).
Next, the operation of the above-described in-vehicle air cleaner device 60 according to embodiment 2 will be described.
As shown in fig. 10 and 11, the connection pipe 110 is inserted into the connection opening 86 of the cylindrical portion 85. By moving the element 70, the connection hole extension 122 is inserted into the first connection hole 121, and the element flange 75 is brought into contact with the wall 82a of the case member 82.
The first connection hole 121 has a long hole shape in a front view. By rotating the element 70, the flange claw portion 78 slides inside the element holder 84. Therefore, the connection hole extension part 122 shown by the dotted line moves as shown by the arrow (10) and moves to the position of the connection hole extension part 122 shown by the solid line. Further, by rotating the element 70, the element 70 is attached to the housing main body 81.
As described above, in the state where the connection hole extension 122 is inserted into the first connection hole 121, the element flange 75 can be rotated to be engaged with the element holder 84. Further, by inserting the connection hole extension 122 into the first connection hole 121, the position alignment can be performed at the time of the assembling operation.
In this embodiment, the first connection hole 121 has a substantially circular arc shape in a front view. However, the present invention is not limited thereto. The first connection hole 121 may have a straight long hole shape, a rectangular shape, or a circular shape as long as the first connection hole 121 is larger than the rotation trajectory of the connection hole extension 122.
The vehicle-mounted air cleaner device of the present invention has been described in connection with the embodiment in which the air cleaner is provided on the left side of the motorcycle. However, the present invention is not limited thereto. The air cleaner may be provided on the front side of the internal combustion engine of the motorcycle, or above the internal combustion engine of the motorcycle. Further, the vehicular air cleaner device of the present invention has been described in connection with the embodiment in a motorcycle application. Alternatively, the in-vehicle air cleaner device may be used for automotive applications and the like. The vehicle-mounted air cleaner device of the present invention can be applied to a conventional vehicle.
