Description

本発明は、車体にエンジンを搭載する際の車体とエンジンの結合方法に関する。   The present invention relates to a method for connecting a vehicle body and an engine when the engine is mounted on the vehicle body.

車体にエンジンを取り付ける場合、オーバヘッドコンベアのハンガーに載置されて搬送される車体に対して、フロアコンベアの搬送台車に載置されて搬送されるエンジンを位置決めし、その状態を維持して搬送台車を上昇させ、車体の左右に予め取り付けられたエンジンマウントのエンジン取付ブラケットに設けたボルト挿通孔に、エンジンに植設したスタッドボルトを下方から夫々挿通し、これらのスタッドボルトにナットを締結して車体にエンジンを取り付けていた。   When the engine is mounted on the vehicle body, the engine mounted on the conveyor carriage of the floor conveyor is positioned relative to the vehicle body that is mounted and transported on the overhead conveyor hanger, and that state is maintained to maintain the transport cart. The stud bolts installed in the engine are inserted from below into the bolt insertion holes provided in the engine mounting brackets of the engine mount that are attached in advance to the left and right of the vehicle body, and nuts are fastened to these stud bolts. The engine was attached to the car body.

この時、車体及びエンジン個々の部品の製作誤差の集積により、ボルト挿通孔の軸心とスタッドボルトの軸心がずれることが多々発生する。このため、ボルト挿通孔の下面開口部をテーパ形状にすると共に、スタッドボルトの先端も先細りテーパ形状にし、前記誤差を吸収してボルト挿通孔にスタッドボルトを挿通するようにしている。しかしながら、ボルト挿通孔の軸心とスタッドボルトの軸心のずれが大きい場合には、前記テーパ形状を施してもスタッドボルトの先端がボルト挿通孔の壁面に当たり、エンジン取付ブラケットを突き上げて、スタッドボルトをボルト挿通孔に挿通することができない。   At this time, the shaft center of the bolt insertion hole and the shaft center of the stud bolt often deviate due to accumulation of manufacturing errors of individual parts of the vehicle body and the engine. For this reason, the lower surface opening of the bolt insertion hole is tapered, and the tip of the stud bolt is also tapered, so that the error is absorbed and the stud bolt is inserted into the bolt insertion hole. However, if the axial center of the bolt insertion hole and the stud bolt are misaligned, even if the taper shape is applied, the tip of the stud bolt hits the wall surface of the bolt insertion hole and pushes up the engine mounting bracket. Cannot be inserted into the bolt insertion hole.

そこで、特許文献１に記載のように、車体に植設した左右のスタッドボルトの長さを異ならせ、先ず長い方のスタッドボルトをエンジン側に設けた一方のボルト孔にエンジンの姿勢を微調整しながら挿通し、次いで短い方のスタッドボルトをエンジン側に設けた他方のボルト孔にエンジンの姿勢を微調整しながら挿通する方法が知られている。 Therefore, as described in Patent Document 1, the lengths of the left and right stud bolts implanted in the vehicle body are made different, and the engine position is finely adjusted in one bolt hole provided on the engine side first. There is known a method of inserting the short stud bolt into the other bolt hole provided on the engine side while finely adjusting the posture of the engine.

特開平８−３００９５４号公報JP-A-8-300954

しかし、特許文献１に記載されているエンジン取付方法においては、エンジンの姿勢を微調整しながらスタッドボルトをボルト孔に挿通しなければならないため、作業工数が大になるという不具合があった。 However, the engine mounting method described in Patent Document 1 has a problem in that the number of work steps is increased because the stud bolt must be inserted into the bolt hole while finely adjusting the attitude of the engine.

本発明は、従来の技術が有するこのような問題点に鑑みてなされたものであり、その目的とするところは、簡易な構成で速やかにエンジンを車体に組み付けることができる車体とエンジンの結合方法を提供しようとするものである。   SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a vehicle body-engine coupling method capable of quickly assembling an engine with a simple structure. Is to provide.

上記課題を解決すべく請求項１に係る発明は、車体にエンジンを取り付ける方法であって、車体に取り付けられたエンジンマウントのエンジン取付ブラケットとフランジ部材との間にエンジン取付ブラケットの姿勢を保持する保持部材を装着し、次いで車体を下降させるかまたはエンジンを上昇させて、エンジン取付ブラケットに設けたボルト挿通孔にエンジンに植設したスタッドボルトを挿通させるものである。 In order to solve the above-mentioned problem, the invention according to claim 1 is a method of attaching an engine to a vehicle body, and maintains the posture of the engine attachment bracket between the engine attachment bracket of the engine mount attached to the vehicle body and the flange member. The holding member is mounted, and then the vehicle body is lowered or the engine is raised, and a stud bolt installed in the engine is inserted into a bolt insertion hole provided in the engine mounting bracket.

また、前記エンジン取付ブラケットに設けたボルト挿通孔に、前記スタッドボルトが挿入される入口側から出口側にかけて先細りのテーパを形成することができるし、前記スタッドボルトの先端にも、先細りのテーパを形成することができる。 Further, a taper taper can be formed in the bolt insertion hole provided in the engine mounting bracket from the inlet side to the outlet side where the stud bolt is inserted, and the tip of the stud bolt is also tapered. Can be formed.

また、前記スタッドボルトの基端部から先端部にかけて刻設されたねじ山は、先端部の方が基端部に比べて低く形成することができる。 Further, the screw thread engraved from the proximal end portion to the distal end portion of the stud bolt can be formed such that the distal end portion is lower than the proximal end portion.

請求項１に係る発明によれば、エンジンマウントのエンジン取付ブラケットとフランジ部材との間にエンジン取付ブラケットの姿勢を保持する保持部材を装着したので、車体とエンジンとの間に位置ずれが発生して、スタッドボルトによってエンジン取付ブラケットを突き上げる力が作用したとしても、エンジン取付ブラケットに設けたボルト挿通孔の姿勢が保持されるため、車体に対するエンジン側の位置ずれを補正しながら、ボルト挿通孔にスタッドボルトを円滑に挿通することができる。 According to the first aspect of the present invention, since the holding member that holds the posture of the engine mounting bracket is mounted between the engine mounting bracket of the engine mount and the flange member, a displacement occurs between the vehicle body and the engine. Even if a force that pushes up the engine mounting bracket by the stud bolt is applied, the position of the bolt insertion hole provided in the engine mounting bracket is maintained, so that the position of the engine side relative to the vehicle body is corrected and the bolt insertion hole is corrected. The stud bolt can be inserted smoothly.

また、ボルト挿通孔にスタッドボルトが挿入される入口側から出口側にかけて先細りのテーパを形成すると共に、スタッドボルトの先端にも先細りのテーパを形成すれば、スタッドボルトがボルト挿通孔の壁面に接触したとしても、スタッドボルトの先端がボルト挿通孔のテーパに倣うので、スタッドボルトが円滑にボルト挿通孔に挿通される。 In addition, if the taper taper is formed from the entrance side to the exit side where the stud bolt is inserted into the bolt insertion hole, and the taper taper is also formed at the tip of the stud bolt, the stud bolt contacts the wall surface of the bolt insertion hole. Even if it does, since the front-end | tip of a stud bolt follows the taper of a bolt insertion hole, a stud bolt is smoothly inserted in a bolt insertion hole.

また、スタッドボルトの基端部から先端部にかけて刻設されたねじ山について、先端部の方を基端部に比べて低く形成すれば、ボルト挿通孔とのクリアランスが大きい先端部を先ず挿入し、次いでボルト挿通孔とのクリアランスが小さい基端部を挿入するので、スタッドボルトが円滑且つ確実にボルト挿通孔に挿通される。 Also, if the thread cut from the base end to the tip of the stud bolt is formed lower than the base end, the tip with the large clearance from the bolt insertion hole is inserted first. Then, since the base end portion having a small clearance from the bolt insertion hole is inserted, the stud bolt is smoothly and reliably inserted into the bolt insertion hole.

State through which the hole is inserted

以下に本発明の実施の形態を添付図面に基づいて説明する。図１に示すように、エンジンＥの重量を支え、且つ防振機能を有するエンジンマウント１は、車体ＷのエンジンルームＷ１に位置する左右のフロントサイドフレームＦに夫々配設されている。８はエンジンＥに植設されたスタッドボルト、９はエンジンマウント１に設けられ、スタッドボルト８が挿通するボルト挿通孔、１３はスタッドボルト８に螺合するナットである。   Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the engine mounts 1 that support the weight of the engine E and have a vibration isolation function are respectively disposed on the left and right front side frames F that are located in the engine room W1 of the vehicle body W. 8 is a stud bolt planted in the engine E, 9 is a bolt insertion hole provided in the engine mount 1 and through which the stud bolt 8 is inserted, and 13 is a nut screwed into the stud bolt 8.

エンジンマウント１は、図２〜図４に示すように、フロントサイドフレームＦにボルトで取り付けられる一対の車体側取付ブラケット２と、これらの車体側取付ブラケット２に固定される略円筒形状のハウジング３と、ハウジング３内に収納される防振弾性部材４と、防振弾性部材４を貫通した状態で防振弾性部材４に固着されるエンジン側取付部材５と、エンジン側取付部材５にボルト６で車体側端部７ａが固定されるエンジン取付ブラケット７を備えてなる。   As shown in FIGS. 2 to 4, the engine mount 1 includes a pair of vehicle body side mounting brackets 2 attached to the front side frame F with bolts, and a substantially cylindrical housing 3 fixed to the vehicle body side mounting brackets 2. An anti-vibration elastic member 4 housed in the housing 3, an engine-side mounting member 5 fixed to the anti-vibration elastic member 4 in a state of passing through the anti-vibration elastic member 4, and a bolt 6 on the engine-side mounting member 5 And an engine mounting bracket 7 to which the vehicle body side end 7a is fixed.

また、エンジン取付ブラケット７のエンジン側端部７ｂには、エンジンＥに植設されたスタッドボルト８が挿通するボルト挿通孔９が設けられている。ボルト挿通孔９には、図５に示すように、スタッドボルト８が挿入される入口側から出口側にかけて先細りのテーパ９ａが形成されている。   In addition, a bolt insertion hole 9 through which a stud bolt 8 planted in the engine E is inserted is provided in the engine side end portion 7 b of the engine mounting bracket 7. As shown in FIG. 5, the bolt insertion hole 9 is formed with a taper taper 9 a that tapers from the inlet side into which the stud bolt 8 is inserted to the outlet side.

また、スタッドボルト８の先端にも、図６に示すように、先細りのテーパ８ａが形成されている。そして、スタッドボルト８の基端部８ｂから先端部８ｃにかけて同じ高さのねじ山８ｄが刻設されている。３ａは中央を開口したカバー部材、１０はハウジング３に内接して固定され、中央に開口部を有するフランジ部材、１１はボルト６とエンジン取付ブラケット７で挟装されるブッシュである。 Further, as shown in FIG. 6, a tapered taper 8 a is also formed at the tip of the stud bolt 8. And the thread 8d of the same height is carved from the base end part 8b of the stud bolt 8 to the front-end | tip part 8c. 3a is a cover member having an opening at the center, 10 is a flange member that is inscribed and fixed to the housing 3, and has an opening at the center, and 11 is a bush that is sandwiched between the bolt 6 and the engine mounting bracket 7.

エンジンマウント１を介してエンジンＥが車体Ｗに取り付けられると、エンジンＥの振動は、エンジン取付ブラケット７と通じてエンジン側取付部材５に伝達されるが、エンジン側取付部材５を内装する防振弾性部材４が弾性変形することによって吸収され、車体Ｗ側に伝達される振動は減衰される。 When the engine E is attached to the vehicle body W via the engine mount 1, the vibration of the engine E is transmitted to the engine side attachment member 5 through the engine attachment bracket 7, but the vibration isolation for incorporating the engine side attachment member 5 is provided. The vibration that is absorbed by elastic deformation of the elastic member 4 and transmitted to the vehicle body W side is attenuated.

また、車体ＷにエンジンＥを搭載する際には、ボルト６を中心としてボルト挿通孔９と反対側のフランジ部材１０とブッシュ１１との間に、略直方体形状の保持部材１２がほぼ隙間のない状態で配設される。保持部材１２は、樹脂や金属などで形成された圧縮に対して強固な部材である。   Further, when the engine E is mounted on the vehicle body W, the substantially rectangular parallelepiped holding member 12 is substantially free of gaps between the flange 6 on the opposite side of the bolt insertion hole 9 and the bush 11 with the bolt 6 as the center. Arranged in a state. The holding member 12 is a member that is strong against compression formed of resin, metal, or the like.

保持部材１２をフランジ部材１０とブッシュ１１との間に配設すると、ボルト挿通孔９を設けたエンジン取付ブラケット７のエンジン側端部７ｂに突き上げる力が作用しても、保持部材１２がボルト６の軸心を支点として作用する力に対抗するストッパの役割を果たすため、エンジン取付ブラケット７は持ち上げられることなく、その姿勢が変化することがない。 If the holding member 12 is disposed between the flange member 10 and the bush 11, the holding member 12 can be connected to the bolt 6 even if a force is applied to the engine side end 7 b of the engine mounting bracket 7 provided with the bolt insertion hole 9. Therefore, the engine mounting bracket 7 is not lifted and its posture does not change.

このような保持部材１２を備えたエンジンマウント１を用いて、車体ＷにエンジンＥを組付ける作業は、先ずオーバヘッドコンベアのハンガー（不図示）に載置されて搬送されて来る車体Ｗに対して、フロアコンベアの搬送台車（不図示）に載置されて搬送されて来るエンジンＥを位置決めする。   The operation of assembling the engine E to the vehicle body W using the engine mount 1 having such a holding member 12 is performed on the vehicle body W that is first carried on a hanger (not shown) of an overhead conveyor. Then, the engine E that is placed and transported on the transport carriage (not shown) of the floor conveyor is positioned.

次いで、エンジンＥを載置した搬送台車を上昇させ、左右のエンジンマウント１のボルト挿通孔９に下方からエンジンＥに植設された左右のスタッドボルト８を同時に挿通させる。この時、図７（ａ）に示すように、車体ＷとエンジンＥとの間に位置ずれが発生すると、スタッドボルト８の先端８ａがボルト挿通孔９の壁面９ａに接触し、エンジン取付ブラケット７のエンジン側端部７ｂには突き上げる力が作用する。 Next, the transport carriage on which the engine E is mounted is raised, and the left and right stud bolts 8 implanted in the engine E from below are simultaneously inserted into the bolt insertion holes 9 of the left and right engine mounts 1. At this time, as shown in FIG. 7 (a), when a displacement occurs between the vehicle body W and the engine E, the tip 8a of the stud bolt 8 comes into contact with the wall surface 9a of the bolt insertion hole 9, and the engine mounting bracket 7 The pushing-up force acts on the engine side end 7b.

すると、エンジン取付ブラケット７のエンジン側端部７ｂを突き上げる力によって、ボルト６の軸心を支点としてエンジン取付ブラケット７の車体側端部７ａを押し下げる力が発生する。しかしながら、保持部材１２が、エンジン取付ブラケット７の車体側端部７ａを押し下げる力のストッパとしての役割を果たすので、エンジン取付ブラケット７は持ち上げられることなく、その姿勢が変化することがない。 Then, a force that pushes up the engine side end portion 7b of the engine mounting bracket 7 generates a force that pushes down the vehicle body side end portion 7a of the engine mounting bracket 7 with the shaft center of the bolt 6 as a fulcrum. However, since the holding member 12 serves as a stopper for a force that pushes down the vehicle body side end 7a of the engine mounting bracket 7, the engine mounting bracket 7 is not lifted and its posture does not change.

次いで、先細りのテーパ８ａが形成されたスタッドボルト８の先端が、姿勢が変化することがないボルト挿通孔９のテーパ９ａに倣って進み、図７（ｂ）に示すように、エンジンＥ側が矢印Ｂ方向に移動することで、車体Ｗに対するエンジンＥ側の位置ずれを補正しながら、エンジンＥに植設された左右のスタッドボルト８は、夫々左右のエンジンマウント１に設けられたボルト挿通孔９に円滑に挿通される。 Next, the tip of the stud bolt 8 formed with the tapered taper 8a advances following the taper 9a of the bolt insertion hole 9 in which the posture does not change. As shown in FIG. The left and right stud bolts 8 implanted in the engine E are respectively inserted into the bolt insertion holes 9 provided in the left and right engine mounts 1 while moving in the B direction while correcting the displacement of the engine E side with respect to the vehicle body W. Is smoothly inserted.

次に、図６に示すエンジンＥに植設された左右のスタッドボルト８の替わりに、図８に示すスタッドボルト１８を用いることができる。このスタッドボルト１８は、その長さを基端部１８ｂの部分と先端部１８ｃの部分とで約等分に分けている。 Next, a stud bolt 18 shown in FIG. 8 can be used in place of the left and right stud bolts 8 implanted in the engine E shown in FIG. The length of the stud bolt 18 is divided approximately equally between the base end portion 18b and the tip end portion 18c.

そして、スタッドボルト１８は、先端に先細りのテーパ１８ａを形成すると共に、基端部１８ｂと先端部１８ｃに刻設されているねじ山について、先端部１８ｃのねじ山１８ｄの高さを基端部１８ｂのねじ山１８ｅの高さに比べて低く形成している。 The stud bolt 18 has a tapered taper 18a at the distal end, and the height of the thread 18d of the distal end 18c is set to the height of the thread engraved at the proximal end 18b and the distal end 18c. It is formed lower than the height of the thread 18e of 18b.

図９（ａ）に示すように、このようなスタッドボルト１８を用いれば、図７（ａ）に示す場合と比べて、先端部１８ｃのねじ山１８ｄの高さと基端部１８ｂのねじ山１８ｅの高さの差分だけ多く車体ＷとエンジンＥとの間に位置ずれが発生していても、図９（ｂ）に示すように、保持部材１２及びテーパ９ａ，１８ａの作用と相俟って、エンジンＥ側が矢印Ｃ方向に移動することで、車体Ｗに対するエンジンＥ側の位置ずれを補正しながら、スタッドボルト１８の先端をボルト挿通孔９に進入させることができる。   As shown in FIG. 9 (a), when such a stud bolt 18 is used, the height of the thread 18d of the distal end portion 18c and the thread 18e of the proximal end portion 18b are compared with the case shown in FIG. 7 (a). Even if there is a positional deviation between the vehicle body W and the engine E by a large difference in height, as shown in FIG. 9B, in combination with the action of the holding member 12 and the tapers 9a and 18a. When the engine E side moves in the direction of the arrow C, the tip end of the stud bolt 18 can enter the bolt insertion hole 9 while correcting the displacement of the engine E side with respect to the vehicle body W.

更に、先細りのテーパ１８ａが形成された先端をボルト挿通孔９に進入させたスタッドボルト１８は、図９（ｃ），（ｄ）に示すように、エンジンＥ側が矢印Ｃ方向に移動することで、車体Ｗに対するエンジンＥ側の位置ずれを補正しながら、先端部１８ｃ、そして基端部１８ｂと、ボルト挿通孔９に円滑に挿通される。   Furthermore, as shown in FIGS. 9C and 9D, the stud bolt 18 having the tip formed with the tapered taper 18a inserted into the bolt insertion hole 9 moves in the direction of the arrow C as shown in FIGS. Then, while correcting the displacement of the engine E side with respect to the vehicle body W, the front end 18c, the base end 18b, and the bolt insertion hole 9 are smoothly inserted.

このように、車体ＷとエンジンＥとの間に位置ずれが発生していても、エンジンＥに植設された左右のスタッドボルト１８は、車体Ｗに対するエンジンＥ側の位置ずれを補正して、夫々左右のエンジンマウント１に設けられたボルト挿通孔９に円滑且つ確実に挿通される。 Thus, even if a positional deviation occurs between the vehicle body W and the engine E, the left and right stud bolts 18 implanted in the engine E correct the positional deviation on the engine E side with respect to the vehicle body W, The bolts are inserted smoothly and reliably into bolt insertion holes 9 provided in the left and right engine mounts 1, respectively.

本発明によれば、車体とエンジンとの間に位置ずれが発生しても、車体に対するエンジン側の位置ずれを補正しながら、左右のエンジンマウントに設けられたボルト挿通孔にエンジンに植設された左右のスタッドボルトを円滑に挿通する車体とエンジンの結合方法を提供することができる。 According to the present invention, even if a positional deviation occurs between the vehicle body and the engine, the engine is implanted in the bolt insertion holes provided in the left and right engine mounts while correcting the positional deviation on the engine side with respect to the vehicle body. Further, it is possible to provide a method for coupling the vehicle body and the engine so that the left and right stud bolts can be smoothly inserted.
