Abstract

<P>PROBLEM TO BE SOLVED: To improve workability in work for fixing an upper part of a damper to a car body. <P>SOLUTION: A hook-like locking projection 31a is disposed in the upper part of the damper 18 and inserted into a locking hole 23c formed in the lower surface of a side frame 11, and the damper 18 is rotated to engage the locking projection 31a with the locking hole 23c, and hence the damper 18 is temporarily fixed to the car body frame 11. In this state, two bolts 40 inserted from the downside are screwed into weld nuts 25 to fix the damper 18. Thus, it is not required that one operator inserts the damper from the downside of the car body and the other operator screws the nuts from the upside of the car body to fix the damper. Therefore, one operator can mount the damper 18, and hence the workability is improved. Especially, the temporarily fixed damper 18 does not fall even if it is not held by a hand, so that screwing work of the bolts 40 into the weld nuts 25 is further facilitated. <P>COPYRIGHT: (C)2005,JPO&NCIPI

【発明の属する技術分野】
本発明は、サスペンション装置のサスペンションアームやナックルの上下動を緩衝するダンパーを車体に取り付けるダンパーの取付構造に関する。
【０００２】
【従来の技術】
自動車のダンパーの上部を車体に支持するダンパーの取付構造が下記特許文献１および特許文献２により公知である。
【０００３】
特許文献１に記載されたものは、ダンパーのコイルスプリングの上端を受ける上部ばね受けをタイヤハウスの内面に設け、ダンパーのピストンロッドの上端が前記上部ばね受けを下から上に貫通してタイヤハウスの上方からナットで固定される。
【０００４】
また特許文献２に記載されたものは、タイヤハウスの内面に設けたブラケットとダンパーのピストンロッドの上端とを、ピストンロッドの上端をその軸線と直交する方向に貫通するボルトにより固定している。

特開２０００−１８６７３８号公報
【特許文献２】
特開平１０−２７３０７３号公報
【０００６】
【発明が解決しようとする課題】
ところで、上記特許文献１に記載されたものは、一人の作業者がタイヤハウスの内部でダンパーを保持し、他の作業者がタイヤハウスの上方からダンパーのピストンロッドの上端を固定する作業を行うので、二人の作業者が必用になって作業効率が悪いという問題がある。
【０００７】
また上記特許文献２に記載されたものは、作業者がタイヤハウスの内部でダンパーを保持し、ブラケットのボルト孔とダンパーのピストンロッドの上端のボルト孔とを位置決めした状態で、ボルトを前記両ボルト孔に挿入する必用があり、一方の手でダンパーを保持して他方の手でボルトを挿入するのが困難で作業に熟練を要するという問題がある。
【０００８】
本発明は前述の事情に鑑みてなされたもので、ダンパーの上部を車体に固定する作業の作業性を高めることを目的とする。
【０００９】
【課題を解決するための手段】
上記目的を達成するために、請求項１に記載された発明によれば、下端がサスペンション装置に接続されたダンパーの上部を車体に固定するダンパーの取付構造において、ダンパーの上部に仮止め部を設け、仮止め部でダンパーを車体に仮止めした状態で、ダンパーを下方から車体に固定することを特徴とするダンパーの取付構造が提案される。
【００１０】
上記構成によれば、ダンパーの上部に設けた仮止め部でダンパーを車体に仮止めし、その状態でダンパーを下方から車体に固定するので、一人の作業者が車体下方からダンパーを挿入し、他の作業者が車体上方からダンパーを固定する必要がなくなり、一人の作業者でダンパーを取り付けることが可能になって作業性が向上する。特に、仮止めしたダンパーは手を離しても落下しないので、それを固定する作業が一層容易になる。
【００１１】
また請求項２に記載された発明によれば、請求項１の構成に加えて、仮止め部はフック状の係止突起であり、この係止突起を車体に形成した係止孔に挿入してダンパーを回転させることで、係止突起を係止孔に係合させてダンパーを車体に仮止めすることを特徴とするダンパーの取付構造が提案される。
【００１２】
上記構成によれば、仮止め部をフック状の係止突起で構成し、係止突起を車体の係止孔に挿入してダンパーを回転させると、係止突起が係止孔に係合してダンパーが車体に仮止めされるので、簡単な作業でダンパーを車体に仮止めすることができる。しかも係止突起が係止孔に係合することで、ダンパーの車体に対する固定が緩んでも、ダンパーが車体から脱落するのを防止することができる。
【００１３】
尚、実施例のサイドフレーム１１は本発明の車体に対応し、実施例の係止突起３１ａは本発明の仮止め部に対応する。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を、添付図面に示した本発明の実施例に基づいて説明する。
【００１５】
図１〜図４は本発明の一実施例を示すもので、図１は自動車のダンパーの縦断面図、図２は図１の２−２線断面図、図３はダンパーの組付時の作用説明図、図４は図３の４−４線断面図である。
【００１６】
図１および図２に示すように、自動車のサイドフレーム１１は断面Ｌ字状の第１部材２１と、断面平板状の第２，第３部材２２，２３とを溶接して四角形断面に構成されており、上下に対向する第１部材２１の下面と第３部材２３の上面との間に筒状のバルクヘッド２４の上下端が溶接される。バルクヘッド２４の内部に連通するように、第１部材２１に円形の開口２１ａが形成され、第３部材２３に円形の開口２３ａ（図２参照）が形成される。第３部材２３の円形の開口２３ａの周囲を囲むように、２個のボルト孔２３ｂ，２３ｂと、２個の係止孔２３ｃ，２３ｃとが形成されており、それらのボルト孔２３ｂ，２３ｂに対応するように第３部材２３の上面に２個のウエルドナット２５，２５が設けられる。
【００１７】
ダンパー１８は、内部にオイルが充填されたシリンダ２６と、シリンダ２６の上端から出没するピストンロッド２７とを備えており、シリンダ２６の下端はゴムブッシュジョイント２８およびボルト２９を介してロアアーム１６の中間部に支持される。
【００１８】
カップ状のピストンロッドホルダ３０と、皿状の上部スプリングシート３１と、円筒状のシリンダカバー３２とが一体に設けられており、ピストンロッドホルダ３０の上面にピストンロッド２７が弾性支持される。即ち、ピストンロッドホルダ３０の上面を挟む上下一対のゴムブッシュ３３，３４をピストンロッド２７が貫通し、ピストンロッド２７に固定したワッシャ３５と、ピストンロッド２７にナット３６で固定されるワッシャ３７との間にゴムブッシュ３３，３４が挟持される。
【００１９】
シリンダ２６の下部に皿状の下部スプリングシート３８が固定されており、シリンダ２６の周囲を囲むように配置されたコイルスプリング３９の上下両端が、上部スプリングシート３１および下部スプリングシート３８にそれぞれ支持される。このとき、上部スプリングシート３１の下面とコイルスプリング３９の上端との間にゴム製のインシュレータ４１が配置される。上部スプリングシート３１には、切り起こしによりフック状に形成した２個の係止突起３１ａ，３１ａと、２個のボルト孔３１ｂ，３１ｂとが設けられる。
【００２０】
予めアセンブリとして組み立てられたダンパー１８は以下のようにして車体に取り付けられる。即ち、ダンパー１８の上部のピストンロッドホルダ３０をサイドフレーム１１の第３部材２３の開口２３ａに下から挿入し、ピストンロッドホルダ３０の下部に固定した上部スプリングシート３１に形成した２個の係止突起３１ａ，３１ａを第３部材２３の係止孔２３ｃ，２３ｃに挿入した後（図３および図４参照）、ダンパー１８をその軸線まわりに回転させて係止突起３１ａ，３１ａを係止孔２３ｃ，２３ｃに係合させることで、ダンパー１８をサイドフレーム１１に仮止めする。このように、ダンパー１８を回転させるだけで仮止めが完了するので、その操作が極めて容易である。ダンパー１８がサイドフレーム１１に仮止めされると、上部スプリングシート３１の２個のボルト孔３１ｂ，３１ｂが第１部材２３の２個のボルト孔２３ｂ，２３ｂに一致する（図１参照）。
【００２１】
従って、この仮止め状態で２本のボルト４０，４０を下方から上部スプリングシート３１の２個のボルト孔３１ｂ，３１ｂおよび第３部材２３の２個のボルト孔２３ｂ，２３ｂに挿入し、第３部材２３の上面の２個のウエルドナット２５，２５に締結することで、ダンパー１８の上部をサイドフレーム１１に取り付けることができる。このとき、ダンパー１８の上端はサイドフレーム１１の第１部材２１の開口２１ａから上方に突出する。
【００２２】
以上のように、ダンパー１８の上部を下方からサイドフレーム１１の開口２３ａ，２１ａに挿入し、かつダンパー１８の挿入方向と同方向である下方からボルト４０，４０を挿入して締結するので、従来のダンパーに上向きに設けたスタッドボルトに上方からナットを締結してダンパーの上部を車体に取り付ける場合に比べて作業性が大幅に向上する。つまり、車体下方から一人の作業者がダンパーを挿入し、他の作業者が車体上方からナットを締結する必要がなくなり、一人の作業者でダンパー１８を取り付けることができる。
【００２３】
しかも係止突起３１ａ，３１ａを係止孔２３ｃ，２３ｃに係合させた仮止め状態では、ダンパー１８は手を離しても落下しないので、ボルト４０，４０を締結する作業が一層容易になる。その後に、ダンパー１８の下端をロアアーム１６にボルト２９で結合すると、ダンパー１８はその軸線まわりに回転不能になるので、万一２本のボルト４０，４０が緩んで抜けてもダンパー１８の上部がサイドフレーム１１から脱落することがない。特に、ダンパー１８の上部がサイドフレーム１１の内部に嵌合しているので、ダンパー１８のサイドフレーム１１からの脱落が一層確実に防止される。
【００２４】
また閉断面を有しているために剛性の高いサイドフレーム１１の下面にダンパー１８の上部を固定したので、ダンパー１８の支持剛性を高めてロアアーム１６から入力される荷重に対するダンパー１８の応答性を高めることができる。更に、ダンパー１８の上部がサイドフレーム１１の内部に収納されるので、サイドフレーム１１の内部空間をダンパー１８の配置に利用してスペース効率の向上を図ることができ、しかもサイドフレーム１１およびダンパー１８を車体左右方向に並置する必要がないため、サスペンション装置の配置スペースを確保するのが容易である。
【００２５】
以上、本発明の実施例を詳述したが、本発明はその要旨を逸脱しない範囲で種々の設計変更を行うことが可能である。
【００２６】
例えば、実施例では後輪のダンパー１８について説明したが、本発明は前輪のダンパーに対しても適用することができる。
【００２７】
また実施例ではダンパー１８の下端をロアアーム１６に接続しているが、それをナックルに接続しても良い。
【００２８】
また実施例ではダンパー１８の上部をサイドフレーム１１に固定しているが、タイヤハウス等の他の部分に固定しても良い。
【００２９】
【発明の効果】
以上のように請求項１に記載された発明によれば、ダンパーの上部に設けた仮止め部でダンパーを車体に仮止めし、その状態でダンパーを下方から車体に固定するので、一人の作業者が車体下方からダンパーを挿入し、他の作業者が車体上方からダンパーを固定する必要がなくなり、一人の作業者でダンパーを取り付けることが可能になって作業性が向上する。特に、仮止めしたダンパーは手を離しても落下しないので、それを固定する作業が一層容易になる。
【００３０】
また請求項２に記載された発明によれば、仮止め部をフック状の係止突起で構成し、係止突起を車体の係止孔に挿入してダンパーを回転させると、係止突起が係止孔に係合してダンパーが車体に仮止めされるので、簡単な作業でダンパーを車体に仮止めすることができる。しかも係止突起が係止孔に係合することで、ダンパーの車体に対する固定が緩んでも、ダンパーが車体から脱落するのを防止することができる。

[0005]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2000-186738 [Patent Document 2]
JP-A-10-273073
[Problems to be solved by the invention]
By the way, in the technique described in Patent Document 1, one worker holds the damper inside the tire house, and another worker works to fix the upper end of the piston rod of the damper from above the tire house. Therefore, there is a problem that two workers are required and work efficiency is poor.
[0007]
Further, in the device described in Patent Document 2, the worker holds the damper inside the tire house, and positions the bolt hole of the bracket and the bolt hole at the upper end of the piston rod of the damper, and then moves the bolt to the both ends. Since it is necessary to insert the bolt into the bolt hole, it is difficult to hold the damper with one hand and insert the bolt with the other hand, and there is a problem that the operation requires skill.
[0008]
The present invention has been made in view of the above circumstances, and has as its object to enhance the workability of fixing an upper portion of a damper to a vehicle body.
[0009]
[Means for Solving the Problems]
To achieve the above object, according to the invention described in claim 1, in a damper mounting structure for fixing an upper portion of a damper whose lower end is connected to a suspension device to a vehicle body, a temporary fixing portion is provided on an upper portion of the damper. A damper mounting structure is proposed, wherein the damper is fixed to the vehicle body from below with the damper temporarily fixed to the vehicle body at the temporary fixing portion.
[0010]
According to the above configuration, the damper is temporarily fixed to the vehicle body with the temporary fixing portion provided at the upper part of the damper, and in this state, the damper is fixed to the vehicle body from below, so one worker inserts the damper from below the vehicle body, There is no need for another worker to fix the damper from above the vehicle body, and it becomes possible for one worker to attach the damper, thereby improving workability. In particular, since the temporarily fixed damper does not fall even if the hand is released, the operation of fixing the damper is further facilitated.
[0011]
According to the second aspect of the invention, in addition to the configuration of the first aspect, the temporary fixing portion is a hook-shaped locking projection, and the locking projection is inserted into a locking hole formed in the vehicle body. A damper mounting structure is proposed, in which the damper is temporarily fixed to the vehicle body by rotating the damper to engage the locking projection with the locking hole.
[0012]
According to the above configuration, the temporary fixing portion is formed by a hook-shaped locking projection, and when the locking projection is inserted into the locking hole of the vehicle body and the damper is rotated, the locking projection engages with the locking hole. Since the damper is temporarily fixed to the vehicle body, the damper can be temporarily fixed to the vehicle body with a simple operation. In addition, since the locking projections engage with the locking holes, even if the damper is loosely fixed to the vehicle body, it is possible to prevent the damper from falling off the vehicle body.
[0013]
The side frame 11 of the embodiment corresponds to the vehicle body of the present invention, and the locking projection 31a of the embodiment corresponds to the temporary fixing portion of the present invention.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described based on examples of the present invention shown in the accompanying drawings.
[0015]
1 to 4 show an embodiment of the present invention. FIG. 1 is a longitudinal sectional view of an automobile damper, FIG. 2 is a sectional view taken along line 2-2 of FIG. 1, and FIG. FIG. 4 is a sectional view taken along line 4-4 in FIG.
[0016]
As shown in FIGS. 1 and 2, the side frame 11 of the automobile is formed in a square cross section by welding a first member 21 having an L-shaped cross section and second and third members 22 and 23 having a flat cross section. The upper and lower ends of the cylindrical bulkhead 24 are welded between the lower surface of the first member 21 and the upper surface of the third member 23 which are vertically opposed. A circular opening 21a is formed in the first member 21 and a circular opening 23a (see FIG. 2) is formed in the third member 23 so as to communicate with the inside of the bulkhead 24. Two bolt holes 23b, 23b and two locking holes 23c, 23c are formed so as to surround the circumference of the circular opening 23a of the third member 23, and these bolt holes 23b, 23b are formed in these bolt holes 23b, 23b. Correspondingly, two weld nuts 25 are provided on the upper surface of the third member 23.
[0017]
The damper 18 includes a cylinder 26 filled with oil therein, and a piston rod 27 protruding and retracting from the upper end of the cylinder 26. The lower end of the cylinder 26 is provided between the lower arm 16 and a rubber bush joint 28 and a bolt 29. Supported by the department.
[0018]
A cup-shaped piston rod holder 30, a dish-shaped upper spring seat 31, and a cylindrical cylinder cover 32 are integrally provided, and a piston rod 27 is elastically supported on the upper surface of the piston rod holder 30. That is, the piston rod 27 penetrates a pair of upper and lower rubber bushes 33 and 34 sandwiching the upper surface of the piston rod holder 30, and includes a washer 35 fixed to the piston rod 27 and a washer 37 fixed to the piston rod 27 with a nut 36. Rubber bushes 33 and 34 are sandwiched between them.
[0019]
A dish-shaped lower spring seat 38 is fixed to a lower portion of the cylinder 26, and upper and lower ends of a coil spring 39 arranged to surround the periphery of the cylinder 26 are supported by the upper spring seat 31 and the lower spring seat 38, respectively. You. At this time, a rubber insulator 41 is arranged between the lower surface of the upper spring seat 31 and the upper end of the coil spring 39. The upper spring seat 31 is provided with two locking projections 31a, 31a formed in a hook shape by cutting and raising, and two bolt holes 31b, 31b.
[0020]
The damper 18 previously assembled as an assembly is attached to the vehicle body as follows. That is, the piston rod holder 30 on the upper part of the damper 18 is inserted into the opening 23a of the third member 23 of the side frame 11 from below, and the two locking members formed on the upper spring seat 31 fixed to the lower part of the piston rod holder 30 After the projections 31a, 31a are inserted into the locking holes 23c, 23c of the third member 23 (see FIGS. 3 and 4), the damper 18 is rotated around its axis to make the locking projections 31a, 31a into the locking holes 23c. , 23c to temporarily fix the damper 18 to the side frame 11. As described above, since the temporary fixing is completed only by rotating the damper 18, the operation is extremely easy. When the damper 18 is temporarily fixed to the side frame 11, the two bolt holes 31b of the upper spring seat 31 match the two bolt holes 23b of the first member 23 (see FIG. 1).
[0021]
Therefore, in this temporarily fixed state, the two bolts 40, 40 are inserted into the two bolt holes 31b, 31b of the upper spring seat 31 and the two bolt holes 23b, 23b of the third member 23 from below, and By fastening to the two weld nuts 25 on the upper surface of the member 23, the upper part of the damper 18 can be attached to the side frame 11. At this time, the upper end of the damper 18 protrudes upward from the opening 21a of the first member 21 of the side frame 11.
[0022]
As described above, the upper part of the damper 18 is inserted into the openings 23a, 21a of the side frame 11 from below, and the bolts 40, 40 are inserted and tightened from below, which is the same direction as the insertion direction of the damper 18, so that the conventional method is used. The workability is greatly improved as compared with the case where a nut is fastened from above to a stud bolt provided on the damper and the upper part of the damper is attached to the vehicle body. In other words, it is not necessary for one worker to insert the damper from below the vehicle body and for another worker to fasten the nut from above the vehicle body, and one worker can attach the damper 18.
[0023]
In addition, in the temporarily fixed state in which the locking projections 31a are engaged with the locking holes 23c, the damper 18 does not drop even if the hand is released, so that the work of fastening the bolts 40, 40 becomes even easier. After that, when the lower end of the damper 18 is connected to the lower arm 16 with the bolt 29, the damper 18 cannot rotate around its axis. Therefore, even if the two bolts 40, 40 are loosened and come off, the upper part of the damper 18 will remain. It does not fall off the side frame 11. In particular, since the upper portion of the damper 18 is fitted into the inside of the side frame 11, the drop of the damper 18 from the side frame 11 is more reliably prevented.
[0024]
Further, since the upper portion of the damper 18 is fixed to the lower surface of the highly rigid side frame 11 due to having a closed cross section, the stiffness of the support of the damper 18 is increased so that the responsiveness of the damper 18 to the load input from the lower arm 16 is improved. Can be enhanced. Further, since the upper portion of the damper 18 is housed inside the side frame 11, the space inside the side frame 11 can be used for arranging the damper 18, thereby improving the space efficiency. Since it is not necessary to arrange the suspension devices in the left-right direction of the vehicle body, it is easy to secure a space for disposing the suspension device.
[0025]
Although the embodiments of the present invention have been described in detail, various design changes can be made in the present invention without departing from the gist thereof.
[0026]
For example, in the embodiment, the rear wheel damper 18 has been described, but the present invention can be applied to a front wheel damper.
[0027]
In the embodiment, the lower end of the damper 18 is connected to the lower arm 16, but it may be connected to a knuckle.
[0028]
In the embodiment, the upper part of the damper 18 is fixed to the side frame 11, but may be fixed to another part such as a tire house.
[0029]
【The invention's effect】
As described above, according to the first aspect of the present invention, the damper is temporarily fixed to the vehicle body by the temporary fixing portion provided on the upper portion of the damper, and the damper is fixed to the vehicle body from below in this state. This eliminates the need for a worker to insert the damper from below the vehicle body and for another worker to fix the damper from above the vehicle body, and allows one worker to attach the damper, thereby improving workability. In particular, since the temporarily fixed damper does not fall even if the hand is released, the operation of fixing the damper is further facilitated.
[0030]
Further, according to the invention described in claim 2, the temporary fixing portion is constituted by a hook-shaped locking projection, and when the locking projection is inserted into the locking hole of the vehicle body and the damper is rotated, the locking projection is formed. Since the damper is temporarily fixed to the vehicle body by engaging with the locking hole, the damper can be temporarily fixed to the vehicle body by a simple operation. In addition, since the locking projections engage with the locking holes, even if the damper is loosely fixed to the vehicle body, it is possible to prevent the damper from falling off the vehicle body.
