Description

本発明は，車両に搭載した内燃機関において，この内燃機関の上面に装着したインタークーラーの冷却を図るために，このインタークーラーに車両における走行風を導くためのダクト装置に関するものである。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a duct device for guiding running air in a vehicle to the intercooler in order to cool an intercooler mounted on the upper surface of the internal combustion engine in an internal combustion engine mounted on the vehicle.

従来，この種のインタークーラーの冷却用ダクト装置は，例えば，特許文献１における図７に開示されているように，車両におけるエンジンルーム内に搭載した内燃機関の上面にインタークーラーを配設し，このインタークーラーの上面と，前記エンジンルームに対する開閉自在なエンジンフードの下面との間に，通風用のダクトを設けることにより，車両の前進走行に際して発生する走行風を，前記ダクト内に車両の前方に向かって開口する空気取入れ口から導入して前記インタークーラーに導くように構成している。   Conventionally, this type of intercooler cooling duct apparatus is provided with an intercooler on the upper surface of an internal combustion engine mounted in an engine room of a vehicle as disclosed in FIG. By providing a ventilation duct between the upper surface of the vehicle and the lower surface of the engine hood that can be freely opened and closed with respect to the engine room, the traveling wind generated during forward traveling of the vehicle is directed toward the front of the vehicle in the duct. It introduce | transduces from the air intake port which opens, and is comprised so that it may guide | induced to the said intercooler.

そして，この従来のダクト装置においては，前記通風用ダクトの前記インタークーラー側への取付けに際して，このダクトのうち車両の走行方向に対してインタークーラーの前側の部分と後ろ側の部分との各々に，下向きに支持棒を設け，この各支持棒を，前記インタークーラー側に設けた受け部に対して下向きに着脱自在に差し込むことによって行うという構成を採用している。
特開２００５−２４７０２８号公報 In this conventional duct device, when the ventilation duct is attached to the intercooler side, the duct is directed downward to each of the front side portion and the rear side portion of the intercooler with respect to the traveling direction of the vehicle. A structure is adopted in which support rods are provided on the base plate and each of the support rods is detachably inserted downward into a receiving portion provided on the intercooler side.
Japanese Patent Laying-Open No. 2005-247028

しかし，前記従来のダクト装置においては，前記通風用ダクトのインタークーラー側への取付けが，これに設けた各支持棒における受け部への下向きへの差し込であることにより，その取付け構造が簡単であるものの，この各支持棒におけるインタークーラー側の各受け部への差し込みが，上方から略真っ直ぐ下向きへ方向への差し込みであることにより，車両におけるエンジンルームとしては，その平面視において，前記インタークーラー側における各装着孔の総てが見えるというように，換言すると，前記インタークーラーの上方にエンジンルームを構成する部材，例えば，カウルトップが覆い被さることがないように，車両の前後方向に沿った開口寸法を大きく構成しなければならならないから，エンジンルームの大型化を招来するという問題がある。   However, in the conventional duct device, the mounting structure of the ventilation duct on the intercooler side is a downward insertion into the receiving portion of each support rod provided on the duct, so that the mounting structure is simple. However, the insertion of the support rods into the receiving portions on the intercooler side of the support rods is performed from the upper side in a substantially straight downward direction. In other words, so that all the mounting holes can be seen, in other words, the opening dimension along the front-rear direction of the vehicle is set so that a member constituting the engine room, for example, a cowl top, does not cover the intercooler. If the engine room is to be enlarged, it must be made large. There is a cormorant problem.

しかも，総ての各支持棒の受け部への差し込みが，上方から略真っ直ぐ下向きへ方向への差し込みであることにより，前記通風用ダクトにおける前後方向へのずれ移動を確実に阻止することができるものの，前記通風用ダクトにおけるインタークーラーからの浮き上がを阻止することができず，従って，前記ダクトのうち車両の走行方向に対してインタークーラーの前側部分と後側部分との両方に，その浮き上がり防止手段を設けるように構成しなけれならないから，構造がその分だけ複雑化するとともに，取付け及び分解に要する手数が嵩むという問題があった。   In addition, since all the support rods are inserted into the receiving portions in a downward direction substantially straight from above, it is possible to reliably prevent the displacement movement of the ventilation duct in the front-rear direction. However, it is not possible to prevent the ventilation duct from floating from the intercooler, and therefore, the duct is prevented from rising at both the front portion and the rear portion of the intercooler with respect to the traveling direction of the vehicle. Since it has to be configured to provide means, there is a problem that the structure is complicated by that amount, and the labor required for mounting and disassembling increases.

本発明は，これらの問題を解消したダクト装置を提供することを技術的課題とするものである。   An object of the present invention is to provide a duct device that solves these problems.

この技術的課題を達成するため本発明の請求項１は， 「車両の前部におけるエンジンルーム内に搭載した内燃機関の上面にインタークーラーを配設し，このインタークーラーの上面に，前記車両における走行風を前記インタークーラーに導くようにした通風用ダクトを配設し，このダクトのうち車両の走行方向に対して前部及び後部の各々を，支持棒とこの支持棒が着脱自在に差し込まれる受け部とから成る支持機構にて，前記インタークーラー，内燃機関又は車両に着脱可能に取付けるように構成して成る冷却用ダクト装置において，
前記各支持機構のうち前記ダクトの前部に位置する支持機構における差し込み方向を下向きにする一方，前記各支持機構のうち前記ダクトの後部に位置する支持機構における差し込み方向を，後方に向かって横向きにする。」
ことを特徴としている。 In order to achieve this technical problem, claim 1 of the present invention is as follows: “An intercooler is disposed on the upper surface of an internal combustion engine mounted in the engine room at the front of the vehicle, and the running wind in the vehicle is disposed on the upper surface of the intercooler. A ventilation duct that guides the air to the intercooler, and each of the duct includes a support bar and a receiving part into which the support bar is detachably inserted with respect to the traveling direction of the vehicle. A cooling duct device configured to be detachably attached to the intercooler, the internal combustion engine or the vehicle by a support mechanism comprising:
The insertion direction of the support mechanism located at the front part of the duct among the respective support mechanisms is directed downward, while the insertion direction of the support mechanism located at the rear part of the duct among the respective support mechanisms is directed sideways toward the rear. To. "
It is characterized by that.

また，本発明の請求項２は，
「前記請求項１の記載において，前記各支持機構のうち前記ダクトの後部に位置する支持機構における支持棒及び受け部の少なくとも一方に，折損可能な脆弱部を設ける。」
ことを特徴としている。 Further, claim 2 of the present invention is
“In the description of claim 1, a breakable weak portion is provided on at least one of the support rod and the receiving portion of the support mechanism located at the rear of the duct among the support mechanisms.”
It is characterized by that.

更にまた，本発明の請求項３は，
「前記請求項１又は２の記載において，前記各支持機構のうち前記ダクトの前部に位置する支持機構における支持棒，及び前記各支持機構のうち前記ダクトの前部に位置する支持機構における支持棒を，前記ダクトに固着する。」
ことを特徴としている。 Furthermore, claim 3 of the present invention provides
“The support rod in the support mechanism located in the front portion of the duct among the respective support mechanisms and the support in the support mechanism located in the front portion of the duct among the respective support mechanisms according to claim 1 or 2. Stick the rod to the duct. "
It is characterized by that.

請求項１の記載において，通風用ダクトのインタークーラーに対する取付けは，先ず，このダクトのうち後部に位置する支持機構における支持棒を，前記ダクトの後方への移動にて，当該後分に位置する支持機構における受け部に差し込みし，次いで，前記ダクトのうち前部に位置する支持機構における支持棒を，前記ダクトの下方への移動にて，当該前部に位置する支持機構における受け部に差し込むことによって行う。   The attachment of the ventilation duct to the intercooler according to claim 1 is carried out by first supporting the support rod in the support mechanism located in the rear portion of the duct by moving the duct rearward. The support rod in the support mechanism located at the front of the duct is then inserted into the support in the support mechanism located at the front by moving the duct downward. Do by.

この取付け状態において，前記ダクトの後方向へのずれ移動を，当該ダクトの前部に位置する支持機構における下向きの差し込みによって防止することができるものでありながら，前記ダクトの後側における浮き上がりを，当該ダクトの前部に位置する支持機構における後方に向かって横向きの差し込みによって防止することができるから，前記ダクトの浮き上がり防止としては，当該ダクトのうち前部のみに設ければ良く，浮き上がり防止の構造を簡単化できるとともに，その取付け及び分解に要する手数を軽減できる。また，前記ダクトに車両における走行風による外力が後ろ向きに作用することで，前記後方に向かって横向きの差し込みの状態が保持することができる。   In this attached state, the rearward movement of the duct can be prevented by the downward insertion of the support mechanism located at the front of the duct, while the lift on the rear side of the duct is Since the support mechanism located at the front part of the duct can be prevented from being inserted sideways toward the rear, the duct can be prevented from being lifted only by being provided at the front part of the duct. The structure can be simplified and the number of steps required for mounting and disassembling can be reduced. Further, an external force caused by running wind in the vehicle acts backward on the duct, so that the state of lateral insertion toward the rear can be maintained.

しかも，前記ダクトにおける後部における取付けが，後方に向かって横向きの差し込みであることにより，前記インタークーラーのうちその後部における上方の部分が，車両におけるエンジンルームを構成する部材，例えば，カウルトップの下側に位置していても，前記ダクトの後部を確実に取付けすることができる。   In addition, since the mounting at the rear part of the duct is a lateral insertion toward the rear, the upper part of the rear part of the intercooler is the lower part of the member constituting the engine room in the vehicle, for example, the lower side of the cowl top. The rear part of the duct can be securely attached even if it is located in the position.

これにより，前記車両のエンジンルームにおける前後方向に沿った開口寸法を，前記従来の場合よりも大幅に狭くすることができるから，前記エンジンルームの小型化を図ることができる。   Thereby, since the opening dimension along the front-back direction in the engine room of the said vehicle can be made narrower than the said conventional case, the size reduction of the said engine room can be achieved.

特に，請求項２に記載した構成によると，前記エンジンルームの開口部を塞ぐエンジンフードに対して当該エンジンフードを下向きに変形するような衝撃を受けた場合に，この衝撃によって，前記後方横向き支持棒における脆弱部が折損することになるから，前記エンジンフードに対する衝撃を効果的に吸収することができる利点がある。   In particular, according to the configuration described in claim 2, when the engine hood that closes the opening of the engine room is subjected to an impact that causes the engine hood to be deformed downward, the impact is supported by the rear sideways support. Since the fragile portion of the rod breaks, there is an advantage that the impact on the engine hood can be effectively absorbed.

また，請求項３に記載した構成によると，受け部への支持棒の差し込みが，受け部をダクト側に設ける場合によりも容易できるから，前記ダクトの取付けを更に簡単化できる利点がある。   Further, according to the configuration described in claim 3, since the insertion of the support rod into the receiving portion can be facilitated even when the receiving portion is provided on the duct side, there is an advantage that the mounting of the duct can be further simplified.

以下，本発明の実施の形態を，図１〜図６の図面について説明する。   Hereinafter, embodiments of the present invention will be described with reference to FIGS.

この図において，符号１は，車両における車体フレームを示し，この車体フレーム１の前部には，開閉自在なエンジンフード３を備えたエンジンルーム２が形成され，このエンジンルーム２内には，多気筒の内燃機関４が，平面視において，そのクランク軸線を車両の走行方向に対して横向きにて搭載されており，この内燃機関４の上面には，当該内燃機関４に付属の排気ターボ過給機（図示せず）の過給機にて圧縮された吸気を冷却するためのインタークーラー５が取付けられている。   In this figure, reference numeral 1 denotes a vehicle body frame in a vehicle, and an engine room 2 having an openable and closable engine hood 3 is formed at the front of the vehicle body frame 1. A cylinder internal combustion engine 4 is mounted in a plan view with its crank axis oriented laterally with respect to the traveling direction of the vehicle, and an exhaust turbocharger attached to the internal combustion engine 4 is mounted on the upper surface of the internal combustion engine 4. An intercooler 5 for cooling the intake air compressed by a supercharger of a machine (not shown) is attached.

この場合において，前記車体フレーム１のうち前記エンジンルーム２と車内とを区画するカウルトップ６は，前記インタークーラー５における後部の上方を覆い被さるように構成されており，換言すると，前記インタークーラー５における後部は，前記カウルトップ６の下方にまで潜り込むという構成になっている。   In this case, a cowl top 6 that partitions the engine room 2 and the interior of the vehicle body frame 1 is configured to cover an upper portion of a rear portion of the intercooler 5, in other words, a rear portion of the intercooler 5. Is configured to sink under the cowl top 6.

符号７は，前記インタークーラー５の上面に配設した通風用のダクトを示し，このダクト７は，偏平状の箱型であり，車両の前進走行に際して発生する走行風を当該ダクト７のうち車両の走行方向における前側面に設けた空気取り入れ口７ａより導入したのち前記インタークーラー５に導いて，前記インタークーラー５を空冷するように構成されている。   Reference numeral 7 denotes a ventilation duct disposed on the upper surface of the intercooler 5. The duct 7 has a flat box shape, and the traveling wind generated when the vehicle travels forward is generated from the duct 7. After being introduced from an air intake port 7a provided on the front side surface in the traveling direction, the air is guided to the intercooler 5 so that the intercooler 5 is air-cooled.

そして，前記ダクト７を，前記インタークーラー５に対して支持するに際しては，以下に述べるように構成する。   And when supporting the said duct 7 with respect to the said intercooler 5, it is comprised as described below.

すなわち，前記ダクト７における後部には，左右一対の支持棒８，９を，後方に向かって横向きに突出するように固着する一方，前記インタークーラー５，前記内燃機関４又は車体フレーム１のいずれかには，前記両後方横向き支持棒８，９に対応する部位にブラケット１０，１１を固着し，この両ブラケット１０，１１の各々には，ゴム等の軟質弾性体製のグロメット１２，１３を装着して，この各両グロメット１２，１３に貫通するようにして穿設した装着孔１２ａ，１３ａ内に，前記両後方横向き支持棒８，９を着脱可能に差し込むことにより，前記ダクト７における後部を支持するように構成している。   That is, a pair of left and right support rods 8 and 9 are fixed to the rear portion of the duct 7 so as to protrude laterally rearward, while being attached to either the intercooler 5, the internal combustion engine 4 or the vehicle body frame 1. The brackets 10 and 11 are fixed to the portions corresponding to the both rear lateral support rods 8 and 9, and grommets 12 and 13 made of a soft elastic material such as rubber are attached to the brackets 10 and 11, respectively. Then, the rear side of the duct 7 is supported by removably inserting the rear lateral support rods 8 and 9 into the mounting holes 12a and 13a drilled so as to penetrate the both grommets 12 and 13, respectively. It is configured to do.

つまり，これら支持棒８，９と，この支持棒８，９が着脱自在に差し込まれる受け部であることろのグロメット１２，１３とで，前記ダクト７における後部を，前記インタークーラー５，前記内燃機関４又は車体フレーム１のいずれかに対して支持する差し込み式の後部支持機構１４，１５を構成している。   That is, the support rods 8 and 9 and the grommets 12 and 13 that are the receiving portions into which the support rods 8 and 9 are detachably inserted, and the rear portion of the duct 7 is connected to the intercooler 5 and the internal combustion engine. The rear support mechanisms 14 and 15 are configured to be supported with respect to either 4 or the vehicle body frame 1.

また，前記ダクト７における前部には，左右一対の支持棒１６，１７を，下向きに突出するように固着する一方，前記インタークーラー５，前記内燃機関４及び車体フレーム１のいずれかには，前記両下向き支持棒１６，１７に対応する部位にブラケット１８，１９を固着し，この両ブラケット１８，１９の各々には，ゴム等の軟質弾性体製のグロメット２０，２１を装着して，この各両グロメット２０，２１に貫通するようにして穿設した装着孔２０ａ，２１ａ内に，前記両下向き支持棒１６，１７を着脱可能に差し込み挿入することにより，前記ダクト７における前部を支持するように構成している。   A pair of left and right support rods 16 and 17 are fixed to the front portion of the duct 7 so as to protrude downward, while any one of the intercooler 5, the internal combustion engine 4 and the vehicle body frame 1 has the Brackets 18 and 19 are fixed to portions corresponding to the downward support rods 16 and 17, and grommets 20 and 21 made of a soft elastic body such as rubber are attached to the brackets 18 and 19, respectively. The front portions of the duct 7 are supported by removably inserting the both downward support rods 16 and 17 into the mounting holes 20a and 21a formed so as to penetrate both the grommets 20 and 21. It is configured.

つまり，これら支持棒１６，１７と，この支持棒１６，１７が着脱自在に差し込まれる受け部であることろのグロメット２０，２１とで，前記ダクト７における前部を，前記インタークーラー５，前記内燃機関４又は車体フレーム１のいずれかに対して支持する差し込み式の前部支持機構２２，２３を構成している。   That is, the support rods 16 and 17 and the grommets 20 and 21 that are the receiving portions into which the support rods 16 and 17 are detachably inserted are connected to the front portion of the duct 7 as the intercooler 5 and the internal combustion engine. Plug-in type front support mechanisms 22 and 23 that support either the engine 4 or the vehicle body frame 1 are configured.

この場合において，前記両後部支持機構１４，１５のうち他方の後部支持機構１５における支持棒９と，前記両前部支持機構２２，２３における支持棒１６，１７は，ダクト７に，折損することがないように強固に固着されているが，前記両後部支持機構１４，１５のち一方の後部支持機構１４における支持棒８は，前記ダクト７に，当該支持棒８に対して上下方向に比較的大きい衝撃力を受けたとき，折損するようにした脆弱部８ａを介して固着するという構成にしている。   In this case, the support rod 9 in the other rear support mechanism 15 of the rear support mechanisms 14 and 15 and the support bars 16 and 17 in the front support mechanisms 22 and 23 are broken into the duct 7. The support bar 8 in one of the rear support mechanisms 14 of the rear support mechanisms 14 and 15 is relatively fixed to the duct 7 in the vertical direction with respect to the support bar 8. When a large impact force is applied, it is configured to be fixed via a fragile portion 8a that is broken.

この構成において，通風用ダクト７のインタークーラー５に対する取付けは，図７に示すように，先ず，このダクト７のうち後部の両後部支持機構１４，１５における支持棒８，９を，前記ダクト７の後方への移動にて，当該後部支持機構１４，１５におけるグロメット１２，１３における装着孔１２ａ，１３ａに差し込みし，次いで，前記ダクト７のうち前部の両前部支持機構２２，２３における支持棒１６，１７を，前記ダクト７の下方への移動にて，当該両前部支持機構２２，２３におけるグロメット２０，２１における装着孔２０ａ，２１ａに差し込むことによって行う。   In this configuration, the ventilation duct 7 is attached to the intercooler 5 as shown in FIG. 7. First, the support rods 8 and 9 in the rear support mechanisms 14 and 15 at the rear of the duct 7 are attached to the duct 7. By rearward movement, the rear support mechanisms 14 and 15 are inserted into the mounting holes 12a and 13a in the grommets 12 and 13, and then the support rods in the front support mechanisms 22 and 23 at the front part of the duct 7 are inserted. 16 and 17 are inserted into the mounting holes 20a and 21a in the grommets 20 and 21 in the front support mechanisms 22 and 23 by moving the duct 7 downward.

なお，前記両後部支持機構１４，１５における受け部であるところのグロメット１２，１３を，白色する等というように光反射を有するものに構成するか，発光性を有するものに構成することにより，この両グロメット１２，１３への前記支持棒８，９の差し込み性を向上できる。   By configuring the grommets 12 and 13 as receiving portions in the rear support mechanisms 14 and 15 to have a light reflection such as whitening, or to have a light emitting property, The insertability of the support rods 8 and 9 into both grommets 12 and 13 can be improved.

前記した取付け状態において，前記ダクト７の前後方向へのずれ移動を，前記両前部支持機構２２，２３における下向きへの差し込みによって防止することができる一方，前記ダクト７の後部における浮き上がりを，前記両後部支持機構１４，１５における後方の向かって横向き方向の差し込みによって防止することができる。   In the above-described mounting state, the shift movement of the duct 7 in the front-rear direction can be prevented by the downward insertion of the front support mechanisms 22, 23, while the lifting at the rear part of the duct 7 can be prevented. This can be prevented by inserting the rear support mechanisms 14 and 15 in the lateral direction toward the rear.

なお，前記ダクト７の前部における浮き上がりは，例えば，前記両前部支持機構２２，２３における支持棒１６，１７の先端に，抜け止め部１６ａ，１７ａを一体に設ける等のように，極く簡単な構成にて阻止することができる。   Note that the floating at the front portion of the duct 7 is extremely high, for example, such that the retaining portions 16a and 17a are integrally provided at the tips of the support rods 16 and 17 in the front support mechanisms 22 and 23. It can be prevented with a simple configuration.

また，前記の取付け状態において，エンジンフード３に，当該エンジンフードを下向きに変形するような衝撃を受けた場合に，この衝撃が，前記ダクト７に伝わり，このダクト７の両後部支持機構１４，１５のうち一方の後部支持機構１４における支持棒８における脆弱部８ａが折損するから，これによって，前記エンジンフード３に対する衝撃を吸収できる。   In addition, when the engine hood 3 receives an impact that deforms the engine hood downward in the mounted state, the impact is transmitted to the duct 7, and both rear support mechanisms 14, 15, the weakened portion 8 a of the support rod 8 in one of the rear support mechanisms 14 is broken, so that the impact on the engine hood 3 can be absorbed.

なお，前記した実施の形態は，各支持機構における支持棒を，ダクト側に設ける一方，この支持棒が差し込まれる受け部を，インタークーラー，内燃機関又は車体フレーム側に設ける場合であったが，本発明は，これに限らず，支持棒を，インタークーラー，内燃機関又は車体フレーム側に設ける一方，受け部を，ダクト側に設ける構成にしても良い。   In the above-described embodiment, the support rod in each support mechanism is provided on the duct side, and the receiving portion into which the support rod is inserted is provided on the intercooler, the internal combustion engine, or the vehicle body frame side. The invention is not limited to this, and the support rod may be provided on the intercooler, the internal combustion engine, or the vehicle body frame side, and the receiving portion may be provided on the duct side.

また，前記後部支持機構における脆弱部は，一方の後部支持機構１４にのみ設けることに限らず，他方の後部支持機構１５に対して設けたり，総ての後部支持機構の各々について設けるという構成にすることができるほか，この脆弱部を受け部の側に設けるように構成することができる。   Further, the fragile portion in the rear support mechanism is not limited to being provided only in one rear support mechanism 14, but is provided for the other rear support mechanism 15 or provided for each of the rear support mechanisms. In addition, it can be configured to provide this weak part on the side of the receiving part.
