本発明は、車両における内燃機関の上方かつ収納スペースの下部の空間に配置される吸気制御装置組立体に関する。 The present invention relates to an intake control device assembly that is placed in a space above an internal combustion engine and below a storage space in a vehicle.

従来、スクータ型車両などの車両における内燃機関の上方かつ収納スペースの下部の空間に配置され、内燃機関の燃焼室内に続く吸気管の少なくとも一部を構成する吸気制御装置組立体が知られている（特許文献1参照）。 Conventionally, there is known an intake control device assembly that is disposed in the space above the internal combustion engine and below the storage space of a vehicle such as a scooter-type vehicle, and that constitutes at least a part of the intake pipe leading to the combustion chamber of the internal combustion engine (see Patent Document 1).

特開２０１１－００１９２７号公報JP 2011-001927 A

特許文献１の吸気制御装置組立体では、吸気制御装置のカプラの向きを下方に傾斜させることによって車両の収納スペースの容量を減少させないように工夫されているが、今日では、車両に要求される機能の増加に伴い、収納ボックス下方の空間は混雑を極めており、さらなるレイアウト自由度の向上を達成できる吸気制御装置組立体が求められている。 In the intake control device assembly of Patent Document 1, the coupler of the intake control device is tilted downward so as not to reduce the volume of the vehicle's storage space. However, today, with the increase in the functionality required of vehicles, the space below the storage box is becoming extremely crowded, and there is a demand for an intake control device assembly that can achieve even greater layout freedom.

本発明の目的は、かかる従来技術の課題に鑑み、車両における吸気制御装置組立体の周辺構成のレイアウト性を向上させることにある。 In view of the problems with the conventional technology, the object of the present invention is to improve the layout flexibility of the peripheral configuration of the intake control device assembly in a vehicle.

本発明の吸気制御装置組立体は、車両における内燃機関の上方かつ収納スペースの下部の空間に配置され、該内燃機関の燃焼室内に続く吸気管の少なくとも一部を構成する吸気制御装置組立体であって、
前記吸気管の一部を構成する第１吸気通路を内部に備えるボディと、該第１吸気通路の内部に回動可能に支持されて該第１吸気通路内に流れる吸気の量を調整する弁体と、該弁体が固定されて該ボディに回動可能に支持され、かつ該ボディの外部に突出した端部を有する弁軸と、該端部に固定されて該弁軸を回動させる操作力を受けるレバー部とを備える吸気制御装置と、
前記第１吸気通路よりも下流側で前記吸気管の一部を構成する第２吸気通路を内部に有して前記ボディに接続されるインレットパイプとを備え、
前記レバー部は、前記操作力をケーブルの引っ張り力によって得るものであり、
前記ケーブルは、ボーデンケーブルのインナケーブルであり、
前記インレットパイプには、前記第２吸気通路内に燃料を噴射する燃料噴射弁が、該燃料噴射弁に繋がる燃料通路を内部に備える燃料ジョイントによって固定され、
前記燃料ジョイントは、前記燃料通路を外部に接続するコネクタ部を備え、
前記コネクタ部は、前記車両の燃料タンクに接続された燃料通路の少なくとも一部を構成する燃料ホースに接続される吸気制御装置組立体において、
前記インレットパイプは、前記ボーデンケーブルのアウタケーブルを固定するケーブルステーを前記レバー部よりも下流側であって前記燃料噴射弁よりも上流側に備え、
前記ケーブルステーと前記レバー部は、前記弁軸の回転中心軸線と前記第１吸気通路が延在する方向である吸気通路方向との双方に直交する方向から見た上面視において前記第１吸気通路の中心線を延長した中心直線で分けられる一方の側に共に配置され、
前記上面視で前記コネクタ部は、前記中心直線で分けられる他方の側又は該中心直線の直上に配置されるとともに前記燃料ジョイントから前記第２吸気通路の上流側に向かって突出し、
前記吸気制御装置を前記第１吸気通路に沿った方向に見たときに、前記回転中心軸線と平行で前記ボディの縁部と接するボディ接線と前記ボディとの間の空間であって、前記回転中心軸線と直交して前記レバー部の縁部と接するレバー接線と前記ボディとの間の空間は、前記燃料ホースの少なくとも一部が配置されるホース空間であることを特徴とする。 The intake control device assembly of the present invention is disposed in a space above an internal combustion engine and below a storage space in a vehicle, and constitutes at least a part of an intake pipe leading to a combustion chamber of the internal combustion engine,
an intake control device comprising: a body having a first intake passage therein that constitutes a part of the intake pipe; a valve body rotatably supported inside the first intake passage and that adjusts the amount of intake air flowing into the first intake passage; a valve shaft to which the valve body is fixed and rotatably supported by the body and that has an end that protrudes outside the body; and a lever portion fixed to the end portion and receiving an operating force that rotates the valve shaft;
an inlet pipe having a second intake passage therein that constitutes a part of the intake pipe downstream of the first intake passage and that is connected to the body,
the lever portion obtains the operating force by a pulling force of a cable,
The cable is an inner cable of a Bowden cable,
a fuel injection valve that injects fuel into the second intake passage is fixed to the inlet pipe by a fuel joint having a fuel passage therein that is connected to the fuel injection valve,
the fuel joint includes a connector portion for connecting the fuel passage to an outside,
In the intake control device assembly, the connector portion is connected to a fuel hose that constitutes at least a part of a fuel passage connected to a fuel tank of the vehicle,
the inlet pipe includes a cable stay for fixing an outer cable of the Bowden cable, the cable stay being located downstream of the lever portion and upstream of the fuel injection valve;
the cable stay and the lever portion are arranged on one side divided by a center line extending from a center line of the first intake passage when viewed from above in a direction perpendicular to both a rotational center axis of the valve shaft and an intake passage direction in which the first intake passage extends,
the connector portion is disposed on the other side of the center line or immediately above the center line in the top view, and protrudes from the fuel joint toward an upstream side of the second intake passage,
When the intake control device is viewed in a direction along the first intake passage, the space between the body and a body tangent that is parallel to the central axis of rotation and touches the edge of the body, and the space between the body and a lever tangent that is perpendicular to the central axis of rotation and touches the edge of the lever portion, is a hose space in which at least a portion of the fuel hose is arranged.

本発明によれば、ケーブルステーをレバー部よりも下流側であって燃料噴射弁よりも上流側のインレットパイプ部分に設けてホース空間を形成し、ケーブルステーとレバー部を第１吸気通路の中心直線の一方の側に配置し、上流側に向かって突出するコネクタ部を他方の側又は該中心直線の直上に配置したので、燃料ホースを容易にホース空間に通過させ、吸気制御装置組立体をコンパクトに形成することができる。 According to the present invention, the cable stay is provided in the inlet pipe section downstream of the lever portion and upstream of the fuel injection valve to form a hose space, the cable stay and lever portion are positioned on one side of the center line of the first intake passage, and the connector portion protruding toward the upstream side is positioned on the other side or directly above the center line, so that the fuel hose can be easily passed through the hose space and the intake control device assembly can be formed compactly.

その際に、コネクタ部を前記他方の側又は該中心直線の直上に配置したので、コネクタ部とホース空間までの間の距離を極力大きくし、また、燃料ホースを屈曲させる角度も小さくできるので、燃料ホースをより容易に配置することができる。 In this case, the connector portion is positioned on the other side or directly above the center line, which maximizes the distance between the connector portion and the hose space and also reduces the angle at which the fuel hose is bent, making it easier to position the fuel hose.

このようにしてコンパクトに形成される吸気制御装置組立体を車両の内燃機関の上方かつ収納スペースの下部の空間に搭載することにより、燃料ホースが吸気制御装置組立体と車両の収納スペースとの間の少ない空間に収納スペースを圧迫することなく配置されるので、収納スペースの大型化や吸気制御装置組立体の周辺空間のレイアウト性を向上させることができる。 By mounting the compact intake control device assembly in this way in the space above the vehicle's internal combustion engine and below the storage space, the fuel hose can be placed in the small space between the intake control device assembly and the vehicle's storage space without taking up too much of the storage space, making it possible to enlarge the storage space and improve the layout of the space around the intake control device assembly.

本発明の車両は、上記の吸気制御装置組立体を備え、該吸気制御装置組立体のコネクタ部に接続される燃料ホースが、該吸気制御装置組立体のホース空間の少なくとも一部に配置されることを特徴とする。 The vehicle of the present invention is characterized in that it is equipped with the above-mentioned intake control device assembly, and a fuel hose connected to the connector portion of the intake control device assembly is disposed in at least a portion of the hose space of the intake control device assembly.

これによれば、燃料ホースを含む燃料配管を、吸気制御装置組立体と収納スペースとの間の少ない空間にコンパクトに配置できるので、収納スペースの大型化や吸気制御装置組立体の周辺空間のレイアウト性を向上させることができる。 This allows the fuel piping, including the fuel hose, to be compactly arranged in the small space between the intake control device assembly and the storage space, making it possible to enlarge the storage space and improve the layout of the space around the intake control device assembly.

以下、図面を用いて本発明の実施形態を説明する。図１は、本発明の一実施形態に係る吸気制御装置組立体を示す。この吸気制御装置組立体１は、スクータ型車両等の車両における内燃機関の上方かつ収納スペースの下部の空間に配置され、該内燃機関の燃焼室内に続く吸気管の少なくとも一部を構成する。 The following describes an embodiment of the present invention with reference to the drawings. Figure 1 shows an intake control device assembly according to one embodiment of the present invention. This intake control device assembly 1 is disposed in a space above an internal combustion engine and below a storage space in a vehicle such as a scooter-type vehicle, and forms at least a part of the intake pipe leading to the combustion chamber of the internal combustion engine.

図１に示すように、吸気制御装置組立体１は、前記吸気管の一部を構成する第１吸気通路２を内部に有するボディ３を備える吸気制御装置４と、第１吸気通路２よりも下流側で前記吸気管の一部を構成する第２吸気通路５を内部に有してボディ３に接続されるインレットパイプ６とを備える。 As shown in FIG. 1, the intake control device assembly 1 includes an intake control device 4 having a body 3 with a first intake passage 2 therein that constitutes part of the intake pipe, and an inlet pipe 6 connected to the body 3 and having a second intake passage 5 therein that constitutes part of the intake pipe downstream of the first intake passage 2.

図２は、吸気制御装置４を第１吸気通路２の中心軸線に沿った方向に見た場合の様子を示す。図２に示すように、吸気制御装置４は、第１吸気通路２の内部に回動可能に支持されて第１吸気通路２内に流れる吸気の量を調整する弁体７と、弁体７が固定されてボディ３に回動可能に支持され、かつボディ３の外部に突出した端部を有する弁軸８と、該端部に固定されて弁軸８を回動させる操作力を受けるレバー部９とを備える。 Figure 2 shows the intake control device 4 when viewed in a direction along the central axis of the first intake passage 2. As shown in Figure 2, the intake control device 4 includes a valve body 7 that is rotatably supported inside the first intake passage 2 and adjusts the amount of intake air flowing into the first intake passage 2, a valve shaft 8 to which the valve body 7 is fixed and rotatably supported by the body 3 and has an end that protrudes outside the body 3, and a lever portion 9 that is fixed to the end and receives an operating force that rotates the valve shaft 8.

図３は、弁軸８の回転中心軸線ＲＡと第１吸気通路２が延在する方向である吸気通路方向との双方に直交する方向から見た平面図である。図３に示すように、レバー部９は、前記操作力をケーブル１０の引っ張り力によって得るものである。ケーブル１０は、ボーデンケーブル１１のインナケーブルである。 Figure 3 is a plan view seen from a direction perpendicular to both the rotational axis RA of the valve shaft 8 and the intake passage direction, which is the direction in which the first intake passage 2 extends. As shown in Figure 3, the lever portion 9 obtains the operating force by the pulling force of the cable 10. The cable 10 is an inner cable of the Bowden cable 11.

インレットパイプ６には、第２吸気通路５内に燃料を噴射する燃料噴射弁１２が、該燃料噴射弁１２に繋がる燃料通路を内部に備える燃料ジョイント１３によって固定される。燃料ジョイント１３は、前記燃料通路を外部に接続するコネクタ部１４を備える。コネクタ部１４は、前記車両の燃料タンクに接続された前記燃料通路の少なくとも一部を構成する燃料ホース１５に接続される。 A fuel injection valve 12 that injects fuel into the second intake passage 5 is fixed to the inlet pipe 6 by a fuel joint 13 that has a fuel passage connected to the fuel injection valve 12 inside. The fuel joint 13 has a connector part 14 that connects the fuel passage to the outside. The connector part 14 is connected to a fuel hose 15 that forms at least a part of the fuel passage that is connected to the fuel tank of the vehicle.

インレットパイプ６は、ボーデンケーブル１１のアウタケーブル１６を固定するケーブルステー１７をレバー部９よりも前記吸気管の下流側であって燃料噴射弁１２よりも上流側に備える。 The inlet pipe 6 is provided with a cable stay 17 that secures the outer cable 16 of the Bowden cable 11 downstream of the lever portion 9 and upstream of the fuel injection valve 12.

ケーブルステー１７とレバー部９は、弁軸８の回転中心軸線ＲＡと第１吸気通路２が延在する方向である吸気通路方向との双方に直交する方向から見た図３で示される上面視において、第１吸気通路２の中心線を延長した中心直線ＣＬで分けられる一方の側に共に配置される。 The cable stay 17 and the lever portion 9 are arranged together on one side divided by a center line CL extending from the center line of the first intake passage 2 in the top view shown in FIG. 3, which is viewed from a direction perpendicular to both the rotational center axis RA of the valve shaft 8 and the intake passage direction in which the first intake passage 2 extends.

前記上面視において、コネクタ部１４は、中心直線ＣＬで分けられる他方の側又は該中心直線ＣＬの直上に配置されるとともに、燃料ジョイント１３から第２吸気通路５の上流側に向かって突出する。 In the top view, the connector portion 14 is disposed on the other side divided by the center line CL or directly above the center line CL, and protrudes from the fuel joint 13 toward the upstream side of the second intake passage 5.

図２に示すように、吸気制御装置４を第１吸気通路２に沿った方向に見た場合、回転中心軸線ＲＡと平行でボディ３の縁部と接するボディ接線ＢＬとボディ３との間の空間であって、回転中心軸線ＲＡと直交してレバー部９の縁部と接するレバー接線ＬＬとボディ３との間の空間は、燃料ホース１５の少なくとも一部が配置されるホース空間ＨＳとなっている。 As shown in FIG. 2, when the intake control device 4 is viewed in a direction along the first intake passage 2, the space between the body 3 and the body tangent line BL, which is parallel to the central axis of rotation RA and in contact with the edge of the body 3, and the space between the body 3 and the lever tangent line LL, which is perpendicular to the central axis of rotation RA and in contact with the edge of the lever portion 9, is the hose space HS in which at least a portion of the fuel hose 15 is disposed.

この構成において、燃料ホース１５を燃料ジョイント１３に接続する際には、燃料ホース１５の一端が燃料ジョイント１３に連結され、他端が車両の燃料タンク又は燃料配管を構成する他の管部に接続される。この接続は、燃料ホース１５をボディ３の外側を通して燃料タンクの方に導いて行われるが、ボディ３の外側を通す燃料ホース１５の部分は、上述のホース空間ＨＳを通過するように配置される。 In this configuration, when connecting the fuel hose 15 to the fuel joint 13, one end of the fuel hose 15 is connected to the fuel joint 13, and the other end is connected to the vehicle's fuel tank or another pipe that constitutes the fuel piping. This connection is made by leading the fuel hose 15 through the outside of the body 3 toward the fuel tank, and the portion of the fuel hose 15 that passes through the outside of the body 3 is positioned so that it passes through the hose space HS described above.

このとき、ボーデンケーブル１１のケーブルステー１７が、レバー部９よりも下流側であって燃料噴射弁１２よりも上流側のインレットパイプ６部分に位置し、かつ燃料ジョイント１３のコネクタ部１４は、中心直線ＣＬについてケーブルステー１７と反対側又は中心直線ＣＬの直上に位置するので、燃料ホース１５は容易にケーブルステー１７の中心直線ＣＬ側を通過し、ホース空間ＨＳを通るように配置される。 At this time, the cable stay 17 of the Bowden cable 11 is located in the inlet pipe 6 downstream of the lever portion 9 and upstream of the fuel injection valve 12, and the connector portion 14 of the fuel joint 13 is located on the opposite side of the center line CL from the cable stay 17 or directly above the center line CL, so the fuel hose 15 easily passes through the center line CL side of the cable stay 17 and is positioned to pass through the hose space HS.

一方、吸気制御装置組立体１が、スクータ型車両等の車両において、内燃機関の上方かつ収納スペースの下部の空間に配置される際には、上記のように燃料ホース１５がホース空間ＨＳを通過させてコンパクトに形成された状態で、従来よりも収納スペースを狭めることのない状態で配置される。このことは、図４、図５を用いて次のように示される。 On the other hand, when the intake control device assembly 1 is placed in the space above the internal combustion engine and below the storage space in a vehicle such as a scooter-type vehicle, the fuel hose 15 passes through the hose space HS as described above, forming a compact shape, and is placed in a state that does not narrow the storage space more than before. This is shown as follows using Figures 4 and 5.

すなわち、図４は、本実施形態の吸気制御装置４における燃料ホース１５の位置と、収納スペース１８との関係を示す。図５は、同様の関係を従来の場合について示す。図４に示すように、吸気制御装置４の外側を通過する燃料ホース１５の部分は、ホース空間ＨＳ内に位置するので、収納スペース１８の下端は、比較的平面状になっており、燃料ホース１５により収納スペース１８が狭められていないことがわかる。 That is, Figure 4 shows the relationship between the position of the fuel hose 15 in the intake control device 4 of this embodiment and the storage space 18. Figure 5 shows a similar relationship in the conventional case. As shown in Figure 4, the portion of the fuel hose 15 that passes outside the intake control device 4 is located within the hose space HS, so the lower end of the storage space 18 is relatively flat, and it can be seen that the storage space 18 is not narrowed by the fuel hose 15.

これに対し、図４の従来の場合には、ケーブルステー１７が吸気制御装置に設けられているため、燃料ホース１５が吸気制御装置の上を通過している。このため、燃料ホース１５により収納スペース１８がかなり狭められている。 In contrast, in the conventional case shown in FIG. 4, the cable stay 17 is attached to the intake control device, so the fuel hose 15 passes over the intake control device. As a result, the storage space 18 is significantly narrowed by the fuel hose 15.

以上のように、本実施形態によれば、ケーブルステー１７をインレットパイプ６部分に設けてホース空間ＨＳを形成し、ケーブルステー１７とレバー部９を第１吸気通路２の中心直線ＣＬの一方の側に配置し、上流側に向かって突出するコネクタ部１４を他方の側又は中心直線ＣＬの直上に配置したので、燃料ホース１５を容易にホース空間ＨＳを通過させ、吸気制御装置組立体１をコンパクトに形成することができる。 As described above, according to this embodiment, the cable stay 17 is provided in the inlet pipe 6 to form the hose space HS, the cable stay 17 and the lever portion 9 are arranged on one side of the center line CL of the first intake passage 2, and the connector portion 14 that protrudes upstream is arranged on the other side or directly above the center line CL, so that the fuel hose 15 can easily pass through the hose space HS and the intake control device assembly 1 can be formed compactly.

その際に、コネクタ部１４を該他方の側又は中心直線ＣＬの直上に配置したので、コネクタ部１４とホース空間ＨＳまでの間の距離を極力大きくし、燃料ホース１５を屈曲させる際の角度も小さくすることができるので、燃料ホース１５をより容易に配置することができる。 In this case, the connector part 14 is positioned on the other side or directly above the center line CL, which maximizes the distance between the connector part 14 and the hose space HS and reduces the angle at which the fuel hose 15 is bent, making it easier to position the fuel hose 15.

このようにしてコンパクトに形成される吸気制御装置組立体１を車両の内燃機関の上方かつ収納スペース１８の下部の空間に搭載することにより、燃料ホース１５が吸気制御装置組立体１と車両の収納スペース１８との間の少ない空間に収納スペース１８を圧迫することなく配置されるので、収納スペース１８の大型化や吸気制御装置組立体１の周辺空間のレイアウト性を向上させることができる。 By mounting the intake control device assembly 1, which is formed compactly in this manner, in the space above the vehicle's internal combustion engine and below the storage space 18, the fuel hose 15 is positioned in the small space between the intake control device assembly 1 and the vehicle's storage space 18 without compressing the storage space 18, making it possible to enlarge the storage space 18 and improving the layout of the space around the intake control device assembly 1.

以上、本発明の実施形態について説明したが、本発明はこれに限定されない。例えば、レバー部９に操作力を付与するケーブル１０は２本に限らず１本であってもよい。この場合、該１本のケーブル１０は、レバー部９に開弁方向の操作力を付与するために用いられ、閉弁方向の操作力は、ばねにより付与されてもよい。 Although the embodiment of the present invention has been described above, the present invention is not limited to this. For example, the number of cables 10 that apply an operating force to the lever portion 9 is not limited to two, and may be one. In this case, the one cable 10 is used to apply an operating force in the valve opening direction to the lever portion 9, and the operating force in the valve closing direction may be applied by a spring.
