上記先行技術は、線状部材をU字状に屈曲させて形成したトーイングフックの対向する線状部材の端部を、車両の幅方向に配設されるクロスメンバの前後両側面に固着している。トーイングフックの対向する中間部にはL字状の補強板の一面を架設し、補強板の他面をクロスメンバの底面に固着している。溶接個所がトーイングフックを構成する線状部材に沿って同方向に設けられているので、一定方向に対しては、剛性が保てるが他の方向に対しては十分な剛性を保つことは難しい。また、補強板によってトーイングフックの対向する端部間を接合しているが、補強板の厚さが必要で、重量が重くなる課題がある。   In the above prior art, the ends of the opposing linear members of the towing hook formed by bending the linear member into a U shape are fixed to the front and rear side surfaces of the cross member disposed in the width direction of the vehicle. Yes. One surface of an L-shaped reinforcing plate is installed at the opposite intermediate portion of the towing hook, and the other surface of the reinforcing plate is fixed to the bottom surface of the cross member. Since the welded portion is provided in the same direction along the linear member constituting the towing hook, rigidity can be maintained in a certain direction, but it is difficult to maintain sufficient rigidity in other directions. Moreover, although the edge parts which a towing hook opposes are joined by the reinforcement board, the thickness of a reinforcement board is required and there exists a subject which becomes heavy.

本発明は、上記課題を解決し、十分な剛性を確保することができる緊締フックの取付構造を提供することを目的とする。   An object of the present invention is to solve the above-mentioned problems and to provide a fastening hook mounting structure that can ensure sufficient rigidity.

本発明は、上記課題を解決するため、車両の車幅方向中央部よりも外方に、車両の前後方向に延びるフロントフレームが設けられ、このフロントフレームに接合されて車幅方向に延びる横方向部材を設けた車体に取り付けられる緊締フックの取付構造において、棒状部材をU字状に折り曲げてフック部を形成した緊締フックの上方に延びる一端部が前記フロントフレームと横方向部材の交差隅部に延出されて、溶接により前記両部材に接合されて取り付けられ、前記緊締フックの上方に延びる他端部が途中から車幅方向に折り曲げられており、該折り曲げ部が前記フロントフレームに溶接により接合されていることにある。   In order to solve the above-mentioned problems, the present invention is provided with a front frame extending in the front-rear direction of the vehicle outside the central portion in the vehicle width direction of the vehicle. In the attachment structure of the fastening hook attached to the vehicle body provided with the member, one end portion extending above the fastening hook formed by bending the rod-like member into a U-shape is formed at the intersection corner of the front frame and the lateral member. The other end portion that extends and is joined to and attached to the both members by welding and is bent in the vehicle width direction from the middle, and the bent portion is joined to the front frame by welding. There is in being.

緊締フックの上方に延びる一端部が前記フロントフレームと横方向部材の交差隅部に延出されて、溶接により前記両部材に接合されて取り付けられており、緊締フックの上方に延びる他端部が途中から車幅方向に折り曲げられており、該折り曲げ部が前記フロントフレームに溶接により接合されているので、荷重が各方向に伝達され、分散されるので、大きな荷重に対応することができる。   One end portion extending above the tightening hook extends to the intersection corner of the front frame and the lateral member, and is joined and attached to both members by welding, and the other end portion extending above the tightening hook is Since it is bent in the vehicle width direction from the middle and the bent portion is joined to the front frame by welding, the load is transmitted and dispersed in each direction, so that a large load can be handled.

Is attached. The tightening hook 2 has a U-shaped hook portion 21 formed by bending a linear member, for example, a rod-shaped member 20 such as a round bar into a substantially U shape. The tightening hook 2 is provided with a bar-like portion 20a, 20b as a vertical portion at one front end and a vertical portion at the other rear end extending above the hook portion 21 at a constant interval on the same vertical plane. The bent portion 22 is formed by bending the rod-like portion 20b as the vertical portion of the other rear end portion in the vehicle width direction, that is, in the horizontal direction at a right angle along the vertical plane that intersects the plane from about halfway. . A connecting member 9 that connects the rod-like portions 20a and 20b is suspended between the rod-like portions 20a and 20b of the tightening hook 2. The connecting member 9 is a rectangular plate-shaped reinforcing plate 90, and both side portions of the reinforcing plate 90 on the back side (inner side of the vehicle body) are joined to one side of the rod-shaped portions 20a and 20b by wire welding w1. A front side portion on the front side (vehicle body outer side) of the reinforcing plate 90 is joined to the one side of the rod-like portion 20a by wire welding w1, and a rear side portion on the front side (vehicle body outer side) of the reinforcing plate 90 is joined to the bar shape. The part 20b is not welded.
The upper side portion 90a of the plate 90 of the connecting member 9 extends to the upper side of the bent portion 22, and the edge portion 90b of the upper side portion 90a is joined to the outer side wall surface 31 of the front frame 3 by line welding w2. Yes.

前記緊締フック2は、前方縦方向に設けられる一方の棒状部20aをフロントフレーム3とフロントフレームサイドメンバ6の接合される交差隅部Rに配置され、この交差隅部Rのフロントフレーム3とフロントフレームサイドメンバ6の両側壁面にそれぞれ線溶接w3により接合されている。また、前記緊締フック2は、他方の棒状部20bの折り曲げ部22をフロントフレーム3の底面32に線溶接w4により接合されている。前記連結部材9のプレート90は、上辺部90aの縁部90bから前記棒状部20bの折り曲げ部22がある側の角部90cにかけて線溶接w2、w5により接合されている。   The tightening hook 2 has one rod-shaped portion 20a provided in the front vertical direction arranged at an intersection corner R where the front frame 3 and the front frame side member 6 are joined. The front frame 3 and the front of the intersection corner R are joined together. The frame side member 6 is joined to both side walls by wire welding w3. The tightening hook 2 has the bent portion 22 of the other rod-shaped portion 20b joined to the bottom surface 32 of the front frame 3 by wire welding w4. The plate 90 of the connecting member 9 is joined by wire welding w2 and w5 from the edge portion 90b of the upper side portion 90a to the corner portion 90c on the side where the bent portion 22 of the rod-like portion 20b is present.

上記実施の形態によれば、緊締フック2は、一方の棒状部20aをフロントフレーム3とフロントフレームサイドメンバ6の接合される交差隅部Rに配置され、この交差隅部Rのフロントフレーム3とフロントフレームサイドメンバ6の両側壁面にそれぞれ線溶接w3により接合されている。また、前記緊締フック2は、他方の棒状部20bの折り曲げ部22をフロントフレーム3の底面32に線溶接w4により接合されている。棒状部20a,20b相互を連結した連結部材9のプレート90の上端部90aは、前記棒状部20bの折り曲げ部22がある側の縁部90bから角部90cにかけて線溶接w2、w5により接合されている。こうして、緊締フック2に加わる応力は、一方の棒状部20aから交差隅部Rのフロントフレーム3とフロントフレームサイドメンバ6の両側壁面を通して、フロントフレーム3とフロントフレームサイドメンバ6に伝わり、車体1の前後方向と車幅方向に分散されて吸収される。一方、他方の棒状部20bに加わる応力は棒状部20bの折り曲げ部22を通してフロントフレーム3の底面32に伝わり、フロントフレーム3の底面32から上下方向および前後方向に分散されて吸収される。このように、荷重が各方向に分散されて伝達されるので、大きな荷重に対応することができる。   According to the above-described embodiment, the fastening hook 2 has one rod-like portion 20a disposed at the intersection corner R where the front frame 3 and the front frame side member 6 are joined. The front frame side member 6 is joined to both side walls by wire welding w3. The tightening hook 2 has the bent portion 22 of the other rod-shaped portion 20b joined to the bottom surface 32 of the front frame 3 by wire welding w4. The upper end portion 90a of the plate 90 of the connecting member 9 connecting the rod-like portions 20a and 20b is joined by wire welding w2 and w5 from the edge portion 90b on the side where the bent portion 22 of the rod-like portion 20b is located to the corner portion 90c. Yes. Thus, the stress applied to the tightening hook 2 is transmitted from one rod-like portion 20a to the front frame 3 and the front frame side member 6 through the side walls of the front frame 3 and the front frame side member 6 at the intersection corner R, and It is dispersed and absorbed in the longitudinal direction and the vehicle width direction. On the other hand, the stress applied to the other rod-shaped portion 20b is transmitted to the bottom surface 32 of the front frame 3 through the bent portion 22 of the rod-shaped portion 20b, and is dispersed and absorbed from the bottom surface 32 of the front frame 3 in the vertical direction and the front-back direction. Thus, since the load is distributed and transmitted in each direction, it is possible to cope with a large load.

前記フロントフレーム3に接合されて車幅方向に延びる横方向部材としてのクロスメンバ4は、前記フック部21の後方他端部としての棒状部20bの上端部を車幅方向に折り曲げた折り曲げ部22と側面視で一致するように設けられているので、クロスメンバ4を通して荷重が各方向に伝達され分散されるので、大きな荷重に対応することができる。 The cross member 4 as a lateral member that is joined to the front frame 3 and extends in the vehicle width direction has a bent portion 22 in which the upper end portion of the rod-like portion 20b as the rear other end portion of the hook portion 21 is bent in the vehicle width direction. Since the load is transmitted and distributed in each direction through the cross member 4, it is possible to cope with a large load.

また、前記緊締フックのフック部21の前方一端部としての棒状部20aと、後方他端部としての棒状部20bに連結部材9を掛け渡して設けている。この連結部材9の両端部を線溶接w1により前記フック部21の前方一端部としての棒状部20aと、後方他端部としての棒状部20bに接合して設け、前記連結部材9の前記前方一端部を線溶接w1により前記フロントフレーム3の側壁面31に接合したので、車両前後方向の荷重に対してせん断方向で荷重を受けるので、大きな荷重に対応することができる。 Further, the connecting member 9 is provided so as to span the rod-shaped portion 20a as one front end portion of the hook portion 21 of the tightening hook and the rod-shaped portion 20b as the other rear end portion. Both end portions of the connecting member 9 are joined to a rod-like portion 20a as a front end portion of the hook portion 21 and a rod-like portion 20b as a rear other end portion by wire welding w1, and the front end of the connecting member 9 is provided. Since the portion is joined to the side wall surface 31 of the front frame 3 by wire welding w1, since a load is received in the shear direction with respect to a load in the vehicle front-rear direction, a large load can be dealt with.

前記連結部材9の上辺部90aの縁部90bを前記フロントフレーム3に線溶接w2により接合し、かつ前記連結部材9の上辺部90aの後方角部90cを線溶接w5により前記フロントフレーム3の側壁面31に接合したので、溶接範囲が増えて強度が増し、向きも変わるので、いろいろな向きの荷重に対応できる。この連結部材9は四角形をした板状の補強プレート90で、補強プレート90の裏側(車体内方側)の両側部を前記棒状部20a,20bの一側に線溶接w1により接合されている。補強プレート90の表側(車体外側)の前方側側部は、前記棒状部20a一側に線溶接w1により接合されており、補強プレート90の表側(車体外側)の後方側側部は、前記棒状部20bには溶接していない。これは、前記緊締フック2が、他方の棒状部20bの折り曲げ部22をフロントフレーム3の底面32に線溶接w4により接合されており、さらに棒状部20a,20b相互を連結した連結部材9のプレート90の上端部90aは、前記棒状部20bの折り曲げ部22がある側の縁部90bから角部90cにかけて線溶接w2、w5により接合されているので、十分な剛性が確保されるからである。 The edge 90b of the upper side 90a of the connecting member 9 is joined to the front frame 3 by line welding w2, and the rear corner 90c of the upper side 90a of the connecting member 9 is connected to the front frame 3 by line welding w5. Since it is joined to the wall surface 31, the welding range is increased, the strength is increased, and the direction is changed, so that it is possible to cope with loads in various directions. The connecting member 9 is a rectangular plate-shaped reinforcing plate 90, and both side portions of the reinforcing plate 90 on the back side (inner side of the vehicle body) are joined to one side of the rod-shaped portions 20a and 20b by wire welding w1. A front side portion on the front side (vehicle body outer side) of the reinforcing plate 90 is joined to the one side of the rod-like portion 20a by wire welding w1, and a rear side portion on the front side (vehicle body outer side) of the reinforcing plate 90 is joined to the bar shape. The part 20b is not welded. This is because the tightening hook 2 has the bent portion 22 of the other rod-shaped portion 20b joined to the bottom surface 32 of the front frame 3 by wire welding w4, and the plate of the connecting member 9 that connects the rod-shaped portions 20a and 20b to each other. This is because the upper end portion 90a of 90 is joined by line welding w2 and w5 from the edge portion 90b on the side where the bent portion 22 of the rod-like portion 20b is located to the corner portion 90c, so that sufficient rigidity is ensured.

なお、前記連結部材9の上辺部90aの後方角部90cに線溶接w5を施したが、前方角部に対しても線溶接を施すこともできる。また、上記実施の形態では前記連結部材9の後方外側に対しては、線溶接を行っていないが、この部分に対しても線溶接を行うことも可能である。   In addition, although the wire welding w5 was given to the back corner part 90c of the upper side part 90a of the said connection member 9, a wire welding can also be given also to a front corner part. Moreover, in the said embodiment, although line welding is not performed with respect to the back outer side of the said connection member 9, it is also possible to perform line welding also with respect to this part.

本発明は、上記実施の形態のみに限定されるものではなく、上記実施の形態では緊締フック2は、車体1の前方左側のフロントフレーム3に対して適用したが、車体1の右側に適用することもできる。また、車体1の後方側のフレームに対して適用することもできる。また、緊締フック2は、車体の前後に適用することもできる。そして、緊締フック2には丸棒を用いたが、角棒でも、板状のものに対しても適用することができる。等、その他、本発明の技術的範囲を変更することなく、適宜変更して実施しうることは言うまでもない。   The present invention is not limited to the above-described embodiment. In the above-described embodiment, the fastening hook 2 is applied to the front frame 3 on the left front side of the vehicle body 1, but is applied to the right side of the vehicle body 1. You can also Further, it can be applied to a frame on the rear side of the vehicle body 1. The tightening hook 2 can also be applied before and after the vehicle body.
