Description

【０００１】
【発明の属する技術分野】
本発明は、牽引フックの取り付けを可能とする車両用牽引装置に関する。
【０００２】
【従来の技術】
車両を牽引するためのフックを車両のサイドフレームに固定するナットと螺合自在とさせることは、特開２００１−１７１５６０号公報に開示される如く知られている。この場合、フックの先端部がバンパリインフォースを通りバンパの下方へと延在する固定式のものと、フックをナットに着脱自在とし、フックをナットに螺合させたときフックの先端部がバンパの前方に位置する着脱式のものがある。
【０００３】
【特許文献１】
特開２００１−１７１５６０号公報
【０００４】
【発明が解決しようとする課題】
従来技術では、ナットをサイドメンバー側の部材に溶接又はネジ止めし、このナットにフックを螺合させていることから、ナットとフックとの螺合部と荷重を受けるフック先端部とのアームが大で、ナットを保持するサイドメンバー側の部材に大きな曲げモーメントを作用させることになり、サイドメンバー側の部材の破損を招きやすい。
【０００５】
ナットをバンパリインフォースを貫通させ、その先端をバンパの位置まで延在させ、この先端にフックを螺合させる試みがあるが、これはナットの長さが伸びフックの長さが短くなったのみで、曲げモーメントの作用するアームの長さには変わりない。したがって、この手段もサイドメンバー側の部材の破損を招きやすい。
【０００６】
それ故に、本発明は、前述した従来技術の不具合を解消させることを解決すべき課題とする。
【０００７】
【課題を解決するための手段】
本発明は、前述した課題を解決するために、フックと螺合するナット部材をバンパリインフォースにナットを用いて固定し、さらに、ナット部材をサイドメンバーの蓋板に溶接して固定する手段を採用する。
【０００８】
この手段の採用は、フックの先端部とナット部材の固定部との間の寸法を小さくし、サイドメンバー側の損傷を小さくさせる。
【０００９】
本発明によれば、車両用牽引フックと螺合可能なナット部材が、車両の幅方向に延在するバンパリインフォースの前壁部の内面と接する段部を有し、前壁部より前方に延出する部分にナットが締め付け可能となっていることを特徴とする車両用牽引装置が提供される。
【００１０】
【発明の実施の形態】
本発明の好ましい実施の形態の車両用牽引装置１はナット部材２を含む。ナット部材２は、その本体部１１の後方のフランジ部３と、前方の段部４と、段部４により作られかつ本体部１１より前方へ延在する小径部５と、小径部５の外周面に設けた雄ネジ部６と、中央部を貫通する雌ネジ部７とを有す。
【００１１】
雄ネジ部６にはナット８が螺合自在となっている。バンパリインフォース９は、断面目の字状のもので、その中央の中空部を画定する前壁部１０は小径部５を通す孔を有し、後壁部１２は本体部１１を通す孔を有し、段部４が前壁部１０の内面に当接する。この当接状態で、ナット８を雄ネジ部６に締め付けると、段部４がバンパリインフォースに密着することになる。
【００１２】
サイドメンバー１３の蓋板１４の内面にフランジ部３を溶接する。これにより、ナット部材２はサイドメンバー１３側の部材１４に固定されることになる。
バンパリインフォース９は蓋板１４に固定される。１５はバンパを示す。
【００１３】
取付に際しては、蓋板１４に溶接されたナット部材２の本体部１１を、バンパリインフォース９の孔に通し、ナット部材２の小径部５をバンパリインフォース９の前壁部１０の前方へ延出させる。バンパリインフォース９を蓋板１４に固定し、次いで、ナット８を雄ネジ部６に締め付ける。かくして、ナット部材２がバンパリインフォース９と蓋板１４に固定される。
【００１４】
車両の牽引を必要とするとき、フック１６をナット部材２に螺合させ、車両を牽引する。このとき、フック１６の軸心方向の荷重は、フランジ部３と蓋板１４との当接部及び段部４とバンパリインフォース９の前壁部１０の内面との当接部で受けることになり、バンパリインフォース９の前後壁部１０，１２の連結壁部が荷重を受けるので、高荷重に耐え得る。さらに、フック１６の先端部とナット８との寸法も小さく、曲げモーメントが小さい。
【００１５】
ナット部材２のバンパリインフォース９に対する回転を防止するため、バンパリインフォース９の前壁部１０の孔を多角形とし、この多角形の部分に対応する小径部５の部分を同じ多角形とするとよい。

BACKGROUND OF THE INVENTION
The present invention relates to a vehicular traction device that enables attachment of a traction hook.
[0002]
[Prior art]
As disclosed in Japanese Patent Application Laid-Open No. 2001-171560, it is known that a hook for pulling a vehicle can be screwed with a nut for fixing to a side frame of the vehicle. In this case, the tip of the hook passes through the bumper reinforcement and extends downward from the bumper, and the hook is detachable from the nut, and when the hook is screwed onto the nut, the tip of the hook is There is a detachable one located in the front.
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 2001-171560
[Problems to be solved by the invention]
In the prior art, the nut is welded or screwed to the member on the side member side, and the hook is screwed into this nut, so that the arm between the nut and the hooked portion of the hook and the tip of the hook that receives the load is provided. A large bending moment is applied to the member on the side member side holding the nut, and the member on the side member side is likely to be damaged.
[0005]
There is an attempt to pass the nut through the bumper reinforcement, extend its tip to the position of the bumper, and screw the hook into this tip, but this is only because the length of the nut is increased and the length of the hook is shortened. The length of the arm on which the bending moment acts does not change. Therefore, this means also tends to cause damage to the member on the side member side.
[0006]
Therefore, this invention makes it the subject which should be solved to eliminate the malfunction of the prior art mentioned above.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention employs means for fixing a nut member screwed to a hook to a bumper reinforcement using a nut, and further fixing the nut member by welding to a lid plate of a side member. To do.
[0008]
By adopting this means, the dimension between the tip end portion of the hook and the fixing portion of the nut member is reduced, and damage on the side member side is reduced.
[0009]
According to the present invention, the nut member that can be screwed to the vehicle pulling hook has the step portion that contacts the inner surface of the front wall portion of the bumper reinforcement extending in the width direction of the vehicle, and extends forward from the front wall portion. There is provided a vehicle traction device characterized in that a nut can be fastened to a protruding portion.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
A vehicle traction device 1 according to a preferred embodiment of the present invention includes a nut member 2. The nut member 2 includes a flange portion 3 behind the main body portion 11, a front step portion 4, a small diameter portion 5 made of the step portion 4 and extending forward from the main body portion 11, and an outer periphery of the small diameter portion 5. It has a male screw part 6 provided on the surface and a female screw part 7 penetrating the center part.
[0011]
A nut 8 can be screwed into the male screw portion 6. The bumper reinforcement 9 is shaped like a cross section, and the front wall portion 10 defining the central hollow portion has a hole through which the small diameter portion 5 passes, and the rear wall portion 12 has a hole through which the main body portion 11 passes. The step 4 abuts against the inner surface of the front wall 10. When the nut 8 is fastened to the male screw portion 6 in this contact state, the stepped portion 4 comes into close contact with the bumper reinforcement.
[0012]
The flange portion 3 is welded to the inner surface of the cover plate 14 of the side member 13. Thereby, the nut member 2 is fixed to the member 14 on the side member 13 side.
The bumper reinforcement 9 is fixed to the lid plate 14. Reference numeral 15 denotes a bumper.
[0013]
At the time of attachment, the main body 11 of the nut member 2 welded to the cover plate 14 is passed through the hole of the bumper reinforcement 9, and the small diameter portion 5 of the nut member 2 is extended forward of the front wall 10 of the bumper reinforcement 9. . The bumper reinforcement 9 is fixed to the cover plate 14, and then the nut 8 is fastened to the male screw portion 6. Thus, the nut member 2 is fixed to the bumper reinforcement 9 and the cover plate 14.
[0014]
When the vehicle needs to be pulled, the hook 16 is screwed into the nut member 2 to pull the vehicle. At this time, the load in the axial direction of the hook 16 is received by the contact portion between the flange portion 3 and the cover plate 14 and the contact portion between the step portion 4 and the inner surface of the front wall portion 10 of the bumper reinforcement 9. Since the connecting wall portions of the front and rear wall portions 10 and 12 of the bumper reinforcement 9 receive a load, they can withstand a high load. Further, the dimensions of the tip of the hook 16 and the nut 8 are small, and the bending moment is small.
[0015]
In order to prevent the nut member 2 from rotating with respect to the bumper reinforcement 9, the hole of the front wall portion 10 of the bumper reinforcement 9 may be a polygon, and the portion of the small diameter portion 5 corresponding to the polygonal portion may be the same polygon.
