Description

本発明は、自動車等の車両の吸気構造に関する。   The present invention relates to an intake structure for a vehicle such as an automobile.

図７は、従来の貨物自動車の吸気構造の構成を模式的に示す斜視図である。   FIG. 7 is a perspective view schematically showing a configuration of a conventional intake structure of a truck.

図７に示すように、従来の貨物自動車の吸気構造１００は、貨物自動車の運転室１０１の背面１０２に沿って配設された吸気管１１０と、吸気管１１０に配管１２０を介して接続されたエアクリーナー１３０とを備える。エアクリーナー１３０は図示しないインテークマニホールドに接続され、これにより、塵芥が除去された空気がインテークマニホールドを介して図示しないエンジンへと導入される。   As shown in FIG. 7, a conventional lorry intake structure 100 is connected to an intake pipe 110 disposed along a back surface 102 of a cab 101 of the lorry, and is connected to the intake pipe 110 via a pipe 120. An air cleaner 130. The air cleaner 130 is connected to an intake manifold (not shown), whereby air from which dust has been removed is introduced to an engine (not shown) through the intake manifold.

また、吸気管１１０は運転室１０１の全高に略等しい高さで背面１０２の上部から吸気口１１０ａを貨物自動車の後方に向けて開口している。なお、図７に示す例においては、貨物自動車の荷台部分は省略して示した。   The intake pipe 110 has a height substantially equal to the total height of the cab 101 and opens from the upper part of the back surface 102 with the intake port 110a toward the rear of the lorry.

以下、本発明の実施の形態について、図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の実施の形態に係る、貨物自動車の吸気構造の構成を模式的に示す斜視図である。   FIG. 1 is a perspective view schematically showing the structure of an intake structure for a truck according to an embodiment of the present invention.

図１に示すように、本実施の形態の貨物自動車の吸気構造１は、貨物自動車の運転室１０１の背面１０２に沿って配設された吸気管１０を有する吸気構造本体１ａを備える。   As shown in FIG. 1, a lorry intake structure 1 according to the present embodiment includes an intake structure main body 1 a having an intake pipe 10 disposed along a back surface 102 of a cab 101 of a lorry.

吸気構造本体１ａは、図２に示すように、吸気管１０と、吸気管１０に接続された天然ゴム又は合成ゴム製等の可撓性を有する材質により作成されたホース１１と、ホース１１に接続された、合成樹脂製の配管１２と、配管１２に接続され、吸気音の低減や吸気の脈動の平滑化を行うレゾネータ１３と、レゾネータ１３に接続された配管１４と、配管１４に接続されたエアクリーナー１５と、エアクリーナー１５及び図示しないインテークマニホールドに接続される配管１６とを有する。なお、配管１４及び１６は、ゴム、合成樹脂、金属等任意の材料により作成されるものとしてもよい。また、図２に示すレゾネータ１３、エアクリーナー１５及び配管１４〜１６のレイアウトは例示であって、各部のレイアウトは任意であってよい。   As shown in FIG. 2, the intake structure body 1 a includes an intake pipe 10, a hose 11 made of a flexible material such as natural rubber or synthetic rubber connected to the intake pipe 10, and a hose 11. A pipe 12 made of synthetic resin, a resonator 13 connected to the pipe 12 for reducing intake noise and smoothing pulsation of the intake air, a pipe 14 connected to the resonator 13, and a pipe 14. And an air cleaner 15 and a pipe 16 connected to an intake manifold (not shown). The pipes 14 and 16 may be made of any material such as rubber, synthetic resin, or metal. Moreover, the layout of the resonator 13, the air cleaner 15, and the pipes 14 to 16 shown in FIG. 2 is an example, and the layout of each part may be arbitrary.

貨物自動車の吸気構造１において吸気構造本体１ａは、図１に示すように、吸気管１０、ホース１１及び、配管１２の一部が、貫通孔１０４ａを介して貨物自動車の荷台１０４上に露出し、残りの構成部品は荷台１０４の裏側にて車台に固定される。   As shown in FIG. 1, in the intake structure 1 of the lorry, the intake structure body 1 a is partially exposed to the cargo bed 104 of the lorry through the through holes 104 a. The remaining components are fixed to the chassis on the back side of the loading platform 104.

吸気管１０は運転室１０１の背面１０２に隣接して配置されるが、背面１０２の周縁が貨物自動車の後方に向かって延出してなるリブ１０３と背面１０２とにより形成される凹部１０２ｘ内に位置する。吸気管１０の厚み、すなわち貨物自動車の前後方向に沿った寸法はリブ１０３の高さより小さい。これにより、吸気管１０は運転室１０１の外形寸法の内側に収まっている。   The intake pipe 10 is disposed adjacent to the back surface 102 of the cab 101, but the periphery of the back surface 102 is located in a recess 102x formed by a rib 103 and a back surface 102 that extend toward the rear of the lorry. To do. The thickness of the intake pipe 10, that is, the dimension along the front-rear direction of the lorry is smaller than the height of the rib 103. Thereby, the intake pipe 10 is accommodated inside the outer dimension of the cab 101.

また、貫通孔１０４ａから、ホース１１との接続部分を含む一部が露出する配管１２は、後述する係止爪１２ａが貫通孔１０４ａの周縁を超えて荷台１０４の表面に係止することにより、荷台１０４において位置決めされている。   In addition, the pipe 12 from which a part including the connecting portion with the hose 11 is exposed from the through hole 104a is locked to the surface of the loading platform 104 by a locking claw 12a described later beyond the periphery of the through hole 104a. It is positioned on the loading platform 104.

次に、吸気管１０は、図３の側面図及び図３に対応する図４の断面図に示すように、合成樹脂製の本体部１０ａと、本体部１０ａの一端である吸気口１０ｃと、吸気口１０ｃの周縁に形成されたファンネル部１０ｂとを備える。なお、本体部１０ａの他端は図２に示すようにホース１１に接続されるが、図３及び４中では省略した。また、図３の側面図は、図１においては貨物自動車の運転室１０１の背面１０２への投影面に平行な面である。   Next, as shown in the side view of FIG. 3 and the cross-sectional view of FIG. 4 corresponding to FIG. 3, the intake pipe 10 includes a synthetic resin main body portion 10 a, an intake port 10 c that is one end of the main body portion 10 a, And a funnel portion 10b formed at the periphery of the air inlet 10c. In addition, although the other end of the main-body part 10a is connected to the hose 11 as shown in FIG. 2, it was abbreviate | omitted in FIG. Further, the side view of FIG. 3 is a plane parallel to the projection surface onto the back surface 102 of the cab 101 of the truck in FIG.

本体部１０ａは、吸気口１０ｃからホース１１にかけて、略Ｓ字形に蛇行した外形を有し、これに対応して、内部に形成される流路１０ｘも略Ｓ字形を有する。更に、吸気口１０ｃは、上方、すなわち鉛直方向に沿って上側に位置する上端１０ａ１が、下側に位置する下端１０ａ２よりも延出して形成されることにより、本体部１０ａにおいて天井部１０ｄを形成するとともに、空気の流れＦ０の入射方向に対して斜行した開口面を有する。   The main body 10a has an outer shape meandering in a substantially S shape from the air inlet 10c to the hose 11, and correspondingly, the flow path 10x formed therein also has a substantially S shape. Further, the air inlet 10c is formed such that the upper end 10a1 located on the upper side, that is, the upper side in the vertical direction, extends from the lower end 10a2 located on the lower side, thereby forming the ceiling 10d in the main body 10a. And an opening surface that is skewed with respect to the incident direction of the air flow F0.

更に、ファンネル部１０ｂは、本体部１０ａと一体成形又は別部材として、本体部１０ａから外側、すなわち本体部１０ａの表面から離隔する向きに延出して形成される。   Further, the funnel portion 10b is formed integrally with the main body portion 10a or as a separate member, and is formed to extend outward from the main body portion 10a, that is, in a direction away from the surface of the main body portion 10a.

以上の構成において、吸気構造本体１ａは本発明の車両の吸気構造に相当し、吸気管１０は本発明の吸気管に相当する。更に、吸気口１０ｃは本発明の吸気口に相当する。   In the above configuration, the intake structure main body 1a corresponds to the intake structure of the vehicle of the present invention, and the intake pipe 10 corresponds to the intake pipe of the present invention. Further, the intake port 10c corresponds to the intake port of the present invention.

このような構成を有する本実施の形態の貨物自動車の吸気構造１は、吸気構造本体１ａにおいて、上端１０ａ１が下端１０ａ２よりも延出することにより天井部１０ｄを形成して、吸入される空気の流れＦ０の入射方向に対して斜行した開口面として形成され吸気口１０ｃを有する吸気管１０を備えたことを特徴とする。   In the intake structure 1 for a lorry vehicle according to the present embodiment having such a configuration, in the intake structure main body 1a, the upper end 10a1 extends beyond the lower end 10a2, thereby forming a ceiling portion 10d, thereby An intake pipe 10 having an intake port 10c formed as an opening surface inclined with respect to the incident direction of the flow F0 is provided.

すなわち、図３及び図４に示すように、吸気口１０ｃにおいては、雨等の水滴は天井部１０ｄ上に滴下することとなり、直接吸気口１０ｃから侵入する恐れが低減される。更に、天井部１０ｄから流れ落ちる水滴は、ファンネル部１０ｂにより堰き止められ、ファンネル部１０ｂの周縁を伝った後に、下端１０ａ２より荷台１０４へ滴下する。これにより、流路１０ｘへの雨等の飛沫の侵入が抑制される。   That is, as shown in FIGS. 3 and 4, at the air inlet 10c, water droplets such as rain drop on the ceiling 10d, and the possibility of directly entering from the air inlet 10c is reduced. Furthermore, the water droplets flowing down from the ceiling portion 10d are blocked by the funnel portion 10b, and after dropping along the periphery of the funnel portion 10b, are dropped onto the loading platform 104 from the lower end 10a2. Thereby, invasion of splashes such as rain into the channel 10x is suppressed.

更に、本実施の形態においては、吸気口１０ｃが、略Ｓ字形に蛇行した本体部１０ａの先端に形成されることから、本体部１０ａの流路１０ｘの断面面積を一定に保ちつつ、本体部１０ａの寸法が増大することが抑制される。   Further, in the present embodiment, since the air inlet 10c is formed at the tip of the main body portion 10a meandering in a substantially S shape, the main body portion is maintained while keeping the cross-sectional area of the flow path 10x of the main body portion 10a constant. An increase in the size of 10a is suppressed.

更に、本実施の形態においては、吸気口１０ｃが、略Ｓ字形に蛇行した本体部１０ａの先端に形成されることから、図４に示すように吸入される空気の流れＦ０は略直交した経路を経て、流れＦ１としてホース１１へ導かれる。流れＦ０〜Ｆ１への方向変換は滑らかであり、圧損が生じにくくなっている。   Further, in the present embodiment, since the intake port 10c is formed at the tip of the main body 10a meandering in a substantially S shape, the flow of air F0 to be sucked is a substantially orthogonal path as shown in FIG. And then led to the hose 11 as a flow F1. The direction change to the flows F0 to F1 is smooth and pressure loss is less likely to occur.

このように、以上の効果を併せて奏する本実施の形態の貨物自動車の吸気構造１は、省スペースで外部からの雨等の飛沫の侵入を防ぎつつ吸気性能を保つことが可能となり、特に軽トラックのような小型の貨物自動車に好適な吸気構造を得ることができる。   As described above, the intake structure 1 for a truck according to the present embodiment, which has the above-described effects, can maintain the intake performance while saving space and preventing the entry of splashes such as rain from the outside. An intake structure suitable for a small truck such as a truck can be obtained.

次に、本実施の形態の貨物自動車の吸気構造１は、可撓性を有するホース１１に接続される合成樹脂製の配管１２が表面に係止爪１２ａを備えたことを特徴とする。   Next, the intake structure 1 for a lorry according to this embodiment is characterized in that a synthetic resin pipe 12 connected to a flexible hose 11 has a locking claw 12a on the surface.

すなわち、配管１２の中心軸Ａによる断面図である図５と、貨物自動車の荷台１０４に平行な平面図である図６に示すように、配管１２は、本体と一体成形され、周方向に等しい角度で配置された係止爪１２ａを備える。係止爪１２ａは、配管１２の延伸方向であって荷台１０４の貫通孔１０４ａの挿入方向に直交する方向からみてくさび状の外形を有し、貫通孔１０４ａと接触する斜面１２ａ２を備える。   That is, as shown in FIG. 5, which is a cross-sectional view of the pipe 12 taken along the central axis A, and FIG. 6, which is a plan view parallel to the cargo bed 104 of the lorry, the pipe 12 is integrally formed with the main body and is equal to the circumferential direction. A locking claw 12a arranged at an angle is provided. The locking claw 12a has a wedge-shaped outer shape when viewed from a direction perpendicular to the insertion direction of the through hole 104a of the loading platform 104 in the extending direction of the pipe 12, and includes an inclined surface 12a2 in contact with the through hole 104a.

このような配管１２を荷台１０４に配設する動作は以下のように行われる。すなわち、貫通孔１０４ａを介して配管１２を荷台１０４の裏面から中心軸Ａに沿って挿入した際に、斜面１２ａ２が貫通孔１０４ａの周縁１０４ａ１に摺動しつつ、係止爪１２ａは配管１２の軸方向に向かって収縮するように変形する。さらに配管１２を挿入し続け、斜面１２ａ２と周縁１０４ａ１との摺動が解除されると、係止爪１２ａは形状が復元される。このとき、正対する係止爪１２ａの両端の幅は貫通孔１０４ａの内径よりも大きいため、配管１２は係止爪１２ａにより荷台１０４に係止され、位置決めされる。   The operation | movement which arrange | positions such a piping 12 to the loading platform 104 is performed as follows. That is, when the pipe 12 is inserted from the back surface of the loading platform 104 along the central axis A through the through-hole 104a, the inclined surface 12a2 slides on the peripheral edge 104a1 of the through-hole 104a, and the locking claw 12a It deforms so as to contract in the axial direction. When the piping 12 is further inserted and sliding between the inclined surface 12a2 and the peripheral edge 104a1 is released, the shape of the locking claw 12a is restored. At this time, since the width of both ends of the locking claw 12a facing each other is larger than the inner diameter of the through hole 104a, the pipe 12 is locked to the loading platform 104 by the locking claw 12a and positioned.

このような係止爪１２ａを有する配管１２を備えたことにより、本実施の形態の貨物自動車の吸気構造１は、貨物自動車への組付けが簡易に行うことができ、作業性や生産性を向上させることができる。また、組付けに要するボルト等の部品点数を削減して、作業性や生産性を向上させるとともに、低コスト化を実現することができる。   By providing the pipe 12 having such a locking claw 12a, the lorry intake structure 1 of the present embodiment can be easily assembled to the lorry, and the workability and productivity are improved. Can be improved. In addition, the number of parts such as bolts required for assembly can be reduced to improve workability and productivity, and cost reduction can be realized.

なお、上記の説明においては、係止爪１２ａの個数は周方向に等角度で４つ配置されるものとしたが、個数は任意であってもよい。また、上記の説明においては、係止爪１２ａは斜面１２ａ２を有するくさび形の側面形状を有するとしたが、斜面１２ａ２の角部１２ａ１を省略した三角形の側面形状を有するものとしてもよい。更に、角部１２ａ１を曲面として形成するようにしてもよい。特にこの場合は、荷台１０４に配設した配管１２の取り外しを容易に行うことができる。   In the above description, the number of the locking claws 12a is four at the same angle in the circumferential direction, but the number may be arbitrary. In the above description, the locking claw 12a has a wedge-shaped side surface shape having the inclined surface 12a2, but may have a triangular side surface shape in which the corner portion 12a1 of the inclined surface 12a2 is omitted. Further, the corner 12a1 may be formed as a curved surface. Particularly in this case, the piping 12 disposed on the loading platform 104 can be easily removed.

このように、貨物自動車の吸気構造１によれば、吸気構造本体１ａにおいて、上端１０ａ１が下端１０ａ２よりも延出することにより天井部１０ｄを形成して、吸入される空気の流れＦ０の入射方向に対して斜行した開口面として形成され吸気口１０ｃを有する吸気管１０を備えたことにより、省スペースで外部からの雨等の飛沫の侵入を防ぎつつ吸気性能を保つことが可能となる。   Thus, according to the intake structure 1 of a lorry, in the intake structure main body 1a, the upper end 10a1 extends beyond the lower end 10a2, thereby forming the ceiling portion 10d, and the incident direction of the flow F0 of the air to be sucked in By providing the intake pipe 10 that is formed as an obliquely inclined opening surface and has the intake port 10c, it is possible to maintain the intake performance while preventing the entry of splashes such as rain from the outside in a space-saving manner.

しかしながら、本発明は上記の実施の形態に限定されるものではない。上記の説明においては、吸気管１０は、平面図において略Ｓ字状の外形を有するものとして説明を行ったが、本発明の吸気管は、一端が鉛直方向に対して略直交して延伸しており、前記一端は、前記開口端の延伸方向に対して斜行するとともに、上端が下端よりも延出して形成された吸気口を有するものであればよく、他の部分の具体的な形状によって限定されるものではない。   However, the present invention is not limited to the above embodiment. In the above description, the intake pipe 10 has been described as having a substantially S-shaped outer shape in plan view. However, the intake pipe of the present invention has one end extending substantially perpendicular to the vertical direction. The one end is inclined as long as the opening end is inclined with respect to the extending direction of the opening end, and the upper end has an intake port formed so as to extend from the lower end. It is not limited by.

したがって、吸気管１０は平面図において鈎型の形状又は逆Ｌ字型の形状を有し、流路１０ｘにおいて空気の流れＦ１が直線となるよう形成されていてもよい。   Therefore, the intake pipe 10 may have a bowl shape or an inverted L shape in a plan view, and may be formed so that the air flow F1 is a straight line in the flow path 10x.

更に、ファンネル部１０ｂは省略した構成であるとしてもよい。   Furthermore, the funnel portion 10b may be omitted.

更に、上記の説明においては、本発明は貨物自動車において実施するものとして説明を行ったが、本発明の車両は、貨物自動車の他、乗用車、二輪車、列車を含むものとしてもよい。更に、ガソリンエンジンの他、ディーゼルエンジン等の内燃機関に適用してもよい。   Furthermore, in the above description, the present invention has been described as being implemented in a cargo vehicle. However, the vehicle of the present invention may include a passenger car, a two-wheeled vehicle, and a train in addition to a cargo vehicle. Furthermore, the present invention may be applied to an internal combustion engine such as a diesel engine in addition to a gasoline engine.

以上のように、本発明は、車両の運転室の背面に隣接して配置される吸気管を備え、前記吸気管は、一端が鉛直方向に対して略直交して延伸しており、前記一端は、その延伸方向に対して斜行するとともに、上端が下端よりも延出して形成された吸気口を有するものであればよく、その他の具体的な目的、用途、構成によって限定されるものではない。   As described above, the present invention includes an intake pipe disposed adjacent to the back surface of a cab of a vehicle, and the intake pipe has one end extending substantially perpendicular to the vertical direction, and the one end Is not limited by other specific purposes, applications, and configurations, as long as it has an intake port that is skewed with respect to the extending direction and that has an upper end extended from the lower end.
