Description

【０００１】
【発明の属する技術分野】
本発明は、車両における部材、例えば、トレーリングアームを車体に取り付けるためボルトに嵌合されるナットを車体の所定位置に保持させる機構に関する。
【０００２】
【従来の技術】
車体に対する従来のトレーリングアーム取付け構造は、図４に例示されているように、サイドシル１等にブラケット２を介して断面略コ字状の保持部３が下向きに固着され、保持部３の外側面に溶着されたナットホルダ４がナット５を抱持して、ナット５が保持部３に形成されたボルト孔６と接するように位置決めされると同時に回り止めされ、保持部３内に配置されたトレーリングアーム前端部７及びゴムブッシュ８、８をボルト９が挿通し、そのボルト９がボルト孔６へ内側から挿入されてナット５にねじ込まれ、トレーリングアーム前端部７が保持部３等の車体側に取り付けられている。
【０００３】
すなわち、サイドシル１と保持部３との隙間Ａが非常に小さくて、車両の艤装時にナット５を上記所定位置に保持しながらボルト９をねじ込むことが困難である場合、車両の艤装工程へ入る前に、保持部３に溶着されたナットホルダ４でナット５を予め抱持しておくようにされているので、艤装工程に先行して保持部３等の車体に電着塗装が施されるとき、ナット５のねじ面に塗料が付着することとなり、従って、ナット５に対するボルト９の係合摩擦力が低下して、ボルト９の軸方向締付け力、すなわち、軸力を適切な大きさで、かつ、確実に得ることが実際上難しいという問題があった。
【０００４】
【発明が解決しようとする課題】
本発明は、狭い空間内においても、車体の所定位置にナットを容易に保持できるようにしようとするものである。
【０００５】
【課題を解決するための手段】
このため、本発明にかかるナット保持機構は、車体部材に形成されたボルト孔に近接して上記車体部材の側面に下方へ開口するように固着され上記ボルト孔に接して配置されたナットの外周面と嵌合するナットホルダと、上記ナットの外面に上端が固着されて下方に延びるナットプレートとを有し、上記ナットプレートに形成された突起の下面が上記車体部材と上下方向に係合している。
【０００６】
すなわち、車体部材に形成されたボルト孔に近接して車体部材の側面に下方へ開口するようにナットホルダが固着され、ボルト孔に接して配置されたナットの外周面とナットホルダとが嵌合していて、ナットがナットホルダにより回り止めされていると共に、ナットの外面に上端が固着されて下方に延びるナットプレートの突起の下面が車体部材と上下方向に係合していて、車体部材の側面に配置されたナットが落下することを防止することができるので、車体部材の側面における空間が狭くても、電着塗装後における車体の組立て時等において、ナットホルダを用いナットを下方からナットホルダに差し込むことにより、車体部材に形成されたボルト孔に接して車体部材の側面にナットを容易に保持させることができる。
【０００７】
【発明の実施の形態】
以下、図面に示す本発明の実施形態例について、前記従来装置との同等部分にはそれぞれ同一符号を付けて説明する。
図１〜図３において、サイドシル１にブラケット２を介して断面略コ字状の保持部３が下向きに固着され、保持部３の外側面にナットホルダ１０のフランジ１１が溶着されており、ナットホルダ１０の立上り部１２に形成された角形端面１３は、保持部３に形成されたボルト孔６と接するように保持部３の外側面に配置されたフランジ付きナット１４の外周面を挟み込んで、ナット１４の位置決め及び回り止め作用を果たしている。
【０００８】
また、ナット１４の下端面には下方に延びる短冊状ナットプレート１５の上端が固着され、ナットプレート１５から切り起こされた舌片１６の先端部が保持部３の外側面に形成された小孔１７内へ挿入されていて、ナット１４の落下が防止されていると同時に、ナットホルダ１０の角形端面１３に対してナット１４が弾力的に嵌合させられている。
【０００９】
さらに、保持部３内に配置されたサスペンションのトレーリングアーム前端部７及びゴムブッシュ８、８をボルト９が挿通し、そのボルト９がボルト孔６へ内側から挿入されてナット１４にねじ込まれ、トレーリングアーム前端部７が保持部３等の車体側に取り付けられている。
【００１０】
上記装置にあっては、保持部３のボルト孔６と接するように保持部３の外側面に配置されたナット１４は、外周面がナットホルダ立上り部１２の角形端面１３に挟み込まれて、位置決め及び回り止めされていると同時に、ナット１４の外面に固着されたナットプレート１５の舌片１６の先端部が保持部３外側面の小孔１７へ挿入されて、ナット１４の落下が防止されているので、サイドシル１と保持部３との隙間Ａが非常に小さくても、ナットプレート１５を手に持ってナット１４を下方からナットホルダ１０へ向かい差し込み、上記舌片１６の先端部を小孔１７へ挿入させることにより、ナットホルダ１０の立上り部１２内にナット１４のフランジを位置せしめた状態で、直ちにナット１４の位置決め及び回り止めとナット１４の落下防止とを容易に可能とすることができる。
【００１１】
すなわち、保持部３のボルト孔６と接するように保持部３の外側面にナット１４を簡便に保持させて、ボルト９をナット１４にねじ込むことができるようになるので、ナット１４は車両の艤装工程時に保持部３の外側面に車体側へ取り付けるようにすることが容易となって、艤装工程に先立って予め保持部３の外側面にナット１４を保持させておく必要がなく、従って、艤装工程に先行する塗装工程で従来のようにナットのねじ面に塗料が付着することは完全に排除できる結果、ナット１４に対するボルト９の軸力を常に適切な大きさで、かつ、確実に得ることができることとなる。
【００１２】
なお、保持部３の外側面に保持されたナット１４に対してボルト９をねじ込むとき、ナット１４のフランジがナットホルダ立上り部１２の内面に係止することにより、ナット１４が外側方へ倒れ込むことを容易に抑制することができ、また、保持部３の外側面とナットホルダ立上り部１２の内面との隙間を図示以上に小さくして、上記作用を一層確実としてもよいのはいうまでもない。
【００１３】
【発明の効果】
本発明にかかるナット保持機構においては、車体部材のボルト孔に近接して車体部材の側面に下方へ開口するように固着されたナットホルダとボルト孔に接して配置されたナットの外周面とが嵌合して、ナットがナットホルダにより回り止めされていると共に、ナットの外面に上端が固着されて下方へ延びるナットプレートの突起の下面が車体部材と上下方向に係合して、車体部材の側面に配置されたナットが落下することを防止することができるため、車体部材の側面における空間が狭くても、電着塗装後における車体の組立て時等において、車体部材に形成されたボルト孔に接して車体部材の側面にナットを容易に保持させることができる結果、車両の艤装時に上記ナットの保持が可能となって、予め車体にナットを取り付けておく必要がなくなり、従って、車体の塗装工程時ナットのねじ面に塗料が付着することを回避できるため、ナットに対するボルトの軸力を常に確保できる特色がある。

BACKGROUND OF THE INVENTION
The present invention relates to a mechanism for holding a member in a vehicle, for example, a nut fitted to a bolt for attaching a trailing arm to the vehicle body at a predetermined position of the vehicle body.
[0002]
[Prior art]
As shown in FIG. 4, the conventional trailing arm mounting structure for the vehicle body has a holding portion 3 having a substantially U-shaped cross section fixed to the side sill 1 or the like via a bracket 2. The nut holder 4 welded to the side surface holds the nut 5 and is positioned so that the nut 5 comes into contact with the bolt hole 6 formed in the holding portion 3. The trailing end of the trailing arm 7 and the rubber bushes 8 and 8 are inserted into the bolts 9, and the bolts 9 are inserted into the bolt holes 6 from the inside and screwed into the nuts 5. It is attached to the car body side.
[0003]
That is, when the gap A between the side sill 1 and the holding portion 3 is very small and it is difficult to screw the bolt 9 while holding the nut 5 in the predetermined position when the vehicle is mounted, before entering the vehicle mounting process. Further, since the nut 5 is held in advance by the nut holder 4 welded to the holding portion 3, when the electrodeposition coating is applied to the vehicle body such as the holding portion 3 prior to the outfitting process. Thus, the paint adheres to the thread surface of the nut 5, and therefore, the frictional force of engagement of the bolt 9 with the nut 5 is reduced, and the axial tightening force of the bolt 9, that is, the axial force is set to an appropriate magnitude, And there was a problem that it was actually difficult to obtain reliably.
[0004]

The present invention is intended to make it possible to easily hold a nut in a predetermined position of a vehicle body even in a narrow space.
[0005]
[Means for Solving the Problems]
For this reason, the nut holding mechanism according to the present invention is an outer periphery of a nut that is fixed so as to open downward on the side surface of the vehicle body member in the vicinity of the bolt hole formed in the vehicle body member and is in contact with the bolt hole. a nut holder for surface mating engagement with the upper end is secured and a nut plate extending downwardly, the lower surface of the protrusion formed on the nut plate in the vertical direction and the vehicle body member to the outer surface of the nut is doing.
[0006]
That is, the nut holder is fixed so as to open downward on the side surface of the vehicle body member in the vicinity of the bolt hole formed in the vehicle body member, and the outer peripheral surface of the nut arranged in contact with the bolt hole and the nut holder are fitted. If you are, together with the nut is prevented from rotating by a nut holder and the lower surface of the projection of the nut plate is fixed the upper end to the outer surface of the nut extending downwardly engaged with the vertical direction as the vehicle body member, the body member The nut placed on the side surface of the body can be prevented from falling, so even if the space on the side surface of the vehicle body member is narrow, the nut holder can be used from below when assembling the vehicle body after electrodeposition coating. By inserting the nut holder, the nut can be easily held on the side surface of the vehicle body member in contact with the bolt hole formed in the vehicle body member.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention shown in the drawings will be described by assigning the same reference numerals to the equivalent parts of the conventional apparatus.
1 to 3, a holding part 3 having a substantially U-shaped cross section is fixed to the side sill 1 through a bracket 2 downward, and a flange 11 of a nut holder 10 is welded to the outer surface of the holding part 3. The square end surface 13 formed on the rising portion 12 of the holder 10 sandwiches the outer peripheral surface of the flanged nut 14 disposed on the outer surface of the holding portion 3 so as to contact the bolt hole 6 formed in the holding portion 3. The nut 14 is positioned and prevented from rotating.
[0008]
Further, the lower end surface of the nut 14 is fixed to the upper end of a strip-shaped nut plate 15 extending downward, and the tip of the tongue piece 16 cut and raised from the nut plate 15 is formed in a small hole formed on the outer surface of the holding portion 3. 17, the nut 14 is prevented from dropping, and at the same time, the nut 14 is elastically fitted to the square end surface 13 of the nut holder 10.
[0009]
Furthermore, a bolt 9 is inserted through the trailing arm front end 7 of the suspension and the rubber bushes 8, 8 disposed in the holding unit 3, and the bolt 9 is inserted into the bolt hole 6 from the inside and screwed into the nut 14. The trailing arm front end portion 7 is attached to the vehicle body side such as the holding portion 3.
[0010]
In the above-described apparatus, the nut 14 disposed on the outer surface of the holding unit 3 so as to contact the bolt hole 6 of the holding unit 3 is positioned with the outer peripheral surface sandwiched between the rectangular end surfaces 13 of the nut holder rising portion 12. At the same time, the tip of the tongue piece 16 of the nut plate 15 fixed to the outer surface of the nut 14 is inserted into the small hole 17 on the outer surface of the holding portion 3 to prevent the nut 14 from falling. Even if the gap A between the side sill 1 and the holding portion 3 is very small, the nut 14 is inserted into the nut holder 10 from below with the nut plate 15 in hand, and the tip of the tongue piece 16 is inserted into the small hole. 17, with the flange of the nut 14 positioned in the rising portion 12 of the nut holder 10, the nut 14 is immediately positioned and prevented from rotating and the nut 14 is prevented from dropping. It can be easily available.
[0011]
That is, the nut 14 can be simply held on the outer surface of the holding portion 3 so as to contact the bolt hole 6 of the holding portion 3 and the bolt 9 can be screwed into the nut 14. It becomes easy to attach to the vehicle body side on the outer surface of the holding portion 3 during the process, and it is not necessary to hold the nut 14 on the outer surface of the holding portion 3 in advance prior to the fitting process. As a result of completely eliminating the adhesion of the paint to the screw surface of the nut as in the past in the painting process preceding the process, the axial force of the bolt 9 against the nut 14 can always be obtained in an appropriate magnitude and surely. Will be able to.
[0012]
Note that when the bolt 9 is screwed into the nut 14 held on the outer surface of the holding portion 3, the nut 14 falls outward due to the flange of the nut 14 engaging with the inner surface of the nut holder rising portion 12. It is needless to say that the above action can be made more reliable by reducing the gap between the outer surface of the holding portion 3 and the inner surface of the nut holder rising portion 12 to be smaller than illustrated. .
[0013]
【The invention's effect】
In the nut holding mechanism according to the present invention, the nut holder that is fixed so as to open downward on the side surface of the vehicle body member in the vicinity of the bolt hole of the vehicle body member and the outer peripheral surface of the nut that is disposed in contact with the bolt hole are provided. The nut is locked by the nut holder, and the lower end of the protrusion of the nut plate that extends downward and is fixed to the outer surface of the nut is engaged with the vehicle body member in the vertical direction . Since the nut arranged on the side surface can be prevented from falling, even if the space on the side surface of the vehicle body member is narrow, the bolt hole formed in the vehicle body member is not suitable for assembling the vehicle body after electrodeposition coating. As a result of being able to easily hold the nut on the side surface of the vehicle body member, it is possible to hold the nut when the vehicle is installed, and it is necessary to attach the nut to the vehicle body in advance. Whilst therefore, it is possible to avoid that the paint adheres to the threaded surface of the vehicle body painting process at the nut, there is a feature that can always ensure the axial force of the bolt relative to the nut.
