JP-A-9-66716

ところで、上記した従来のサスペンション装置では、操縦安定性や乗り心地性能などの車両性能確認実験を行う際には、複数種類のスプリングやショックアブソーバを用意し、これらを交換しながら行う必要がある。   By the way, in the above-described conventional suspension device, when performing vehicle performance confirmation experiments such as steering stability and riding comfort performance, it is necessary to prepare a plurality of types of springs and shock absorbers and replace them.

そこで、本発明は、複数種類のスプリングやショックアブソーバを用意することなく、操縦安定性などの車両性能確認実験を行えるようにすることを目的としている。   Therefore, an object of the present invention is to enable vehicle performance confirmation experiments such as steering stability without preparing a plurality of types of springs and shock absorbers.

本発明は、車輪を車体に対して上下動可能に連結するサスペンションアームとその上方位置の車体との間に衝撃吸収体を設け、この衝撃吸収体の下端取付位置をサスペンションアームの車幅方向に可変としたことを最も主要な特徴とする。   According to the present invention, an impact absorber is provided between a suspension arm that connects a wheel to the vehicle body so as to be movable up and down, and a vehicle body at a position above the suspension arm, and the lower end mounting position of the impact absorber is arranged in the vehicle width direction of the suspension arm. The main feature is that it is variable.

本発明によれば、衝撃吸収体の下端をサスペンションアームの車幅方向適宜位置に取り付けることでレバー比を変更することができ、衝撃吸収体を複数種用意することなく操縦安定性などの車両性能確認実験を行うことができる。   According to the present invention, the lever ratio can be changed by attaching the lower end of the shock absorber at an appropriate position in the vehicle width direction of the suspension arm, and vehicle performance such as steering stability without preparing a plurality of types of shock absorbers. Confirmation experiments can be performed.

以下、本発明の実施の形態を図面に基づき説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の第１の実施形態を示す自動車のサスペンション装置の斜視図であり、左前輪部分を車両前方から見た図に相当する。また、図２は図１の要部の拡大した斜視図で、図３は図１のサスペンション装置を車両前方から見た正面図である。なお、図中で矢印ＦＲ方向が車両前側、矢印ＬＨ方向が車両左側、矢印ＵＰ方向が車両上側にそれぞれ対応している。   FIG. 1 is a perspective view of an automobile suspension device showing a first embodiment of the present invention, and corresponds to a view of a left front wheel portion viewed from the front of the vehicle. 2 is an enlarged perspective view of the main part of FIG. 1, and FIG. 3 is a front view of the suspension device of FIG. 1 as viewed from the front of the vehicle. In the figure, the arrow FR direction corresponds to the vehicle front side, the arrow LH direction corresponds to the vehicle left side, and the arrow UP direction corresponds to the vehicle upper side.

このサスペンション装置は、車幅方向に沿って互いにほぼ平行に配置してあるアッパアーム１とロアアーム３とを備えるダブルウィッシュボーン式のサスペンションであり、アッパアーム１とロアアーム３のそれぞれの車幅方向外側の先端１ａ，３ａに、車輪５を取り付けてあるナックル７の上下両端７ａ，７ｂを、連結具であるボールジョイント１０，２０を介して上下方向に揺動可能に連結している。   This suspension device is a double wishbone type suspension having an upper arm 1 and a lower arm 3 arranged substantially parallel to each other along the vehicle width direction. Upper and lower ends 7a and 7b of a knuckle 7 to which a wheel 5 is attached are connected to 1a and 3a via a ball joint 10 and 20 as a connecting tool so as to be swingable in the vertical direction.

上記したサスペンション装置を備える自動車の車体は、車幅方向外側にて車体前後方向に延びる車体骨格部材であるサイドメンバ９を備え、このサイドメンバ９の下部に、車幅方向に延びるサスペンションメンバ１１の取付端部１１ａを連結して、この取付端部１１ａに、ロアアーム３の二股に分岐した２箇所の基端部３ｂを、車両前後方向を中心軸とする回転軸部１３を介して回転可能に連結する。   A vehicle body including the suspension device described above includes a side member 9 that is a vehicle body skeleton member that extends in the vehicle longitudinal direction on the outer side in the vehicle width direction, and a suspension member 11 that extends in the vehicle width direction is provided below the side member 9. The attachment end 11a is connected to the attachment end 11a so that two base end portions 3b branched into two forks of the lower arm 3 can be rotated through a rotation shaft portion 13 having the vehicle longitudinal direction as a central axis. Link.

一方、サイドメンバ９の上部にて上方に向けて突出して設けてある前後一対のアッパアーム取付ブラケット１５に、アッパアーム１の二股に分岐した２箇所の基端部１ｂを、車両前後方向を中心軸とする回転軸部１７を介して回転可能に連結する。   On the other hand, a pair of front and rear upper arm mounting brackets 15 projecting upward at the upper part of the side member 9 are provided with two base end portions 1b branched into two branches of the upper arm 1, with the vehicle longitudinal direction as the central axis. It connects so that it can rotate via the rotating shaft part 17 which carries out.

上記した前後一対のアッパアーム取付ブラケット１５相互間のサイドメンバ９上にはアッパブラケット２１を設け、このアッパブラケット２１とロアアーム３との間に、衝撃吸収体２３を介装している。   An upper bracket 21 is provided on the side member 9 between the pair of front and rear upper arm mounting brackets 15 described above, and an impact absorber 23 is interposed between the upper bracket 21 and the lower arm 3.

衝撃吸収体２３は、コイルスプリング２５とショックアブソーバ２７とを備え、上端２３ａを前記したアッパブラケット２１に、車幅方向に下端２３ｂが移動可能となるよう揺動可能に連結し、下端２３ｂを取付部としてのロアブラケット２９に、車両前後方向を中心軸とする連結ピン３１を介して回転可能に連結する。   The shock absorber 23 includes a coil spring 25 and a shock absorber 27. The upper end 23a is connected to the above-described upper bracket 21 so that the lower end 23b can move in the vehicle width direction, and the lower end 23b is attached. A lower bracket 29 serving as a portion is rotatably connected via a connecting pin 31 having a vehicle longitudinal direction as a central axis.

ロアブラケット２９は、衝撃吸収体２３の下端２３ｂが挿入されて上記した連結ピン３１を軸支する一対の軸支持片２９ａを備え、その軸支持片２９ａの下部に、車幅方向に向けて貫通するガイド孔２９ｂを設け、このガイド孔２９ｂに、ロアアーム３上に車幅方向に沿って延びるガイド部としてのガイドレール３３を挿入している。   The lower bracket 29 includes a pair of shaft support pieces 29a into which the lower end 23b of the shock absorber 23 is inserted and pivotally supports the connection pin 31 described above. The lower bracket 29 penetrates the lower portion of the shaft support piece 29a in the vehicle width direction. A guide hole 33 is formed, and a guide rail 33 as a guide portion extending along the vehicle width direction is inserted on the lower arm 3 into the guide hole 29b.

ロアブラケット２９は、ガイド孔２９ｂの車両前方側の側部に膨出部２９ｃを備え、この膨出部２９ｃに車幅方向に沿って貫通するねじ孔２９ｄを形成してナット部を構成している。このねじ孔２９ｄに、ガイドレール３３に対して平行に延びるボルトとしてのスライド用ボルト３５をねじ込み、スライド用ボルト３５の車幅方向内側の基端部を、ロアアーム３上に固定してあるブラケット３７に回転可能に取り付ける。この際スライド用ボルト３５は、その頭部３５ａがブラケット３７にほぼ接触する位置にて軸方向に移動不能とする。   The lower bracket 29 is provided with a bulging portion 29c at a side of the guide hole 29b on the vehicle front side, and a screw hole 29d penetrating along the vehicle width direction is formed in the bulging portion 29c to constitute a nut portion. Yes. A slide bolt 35 as a bolt extending parallel to the guide rail 33 is screwed into the screw hole 29d, and a base end portion on the inner side in the vehicle width direction of the slide bolt 35 is fixed on the lower arm 3. Attach to be rotatable. At this time, the sliding bolt 35 is made immovable in the axial direction at a position where the head portion 35 a substantially contacts the bracket 37.

上記したスライド用ボルト３５を回転させることで、ロアブラケット２９をガイドレール３３に沿って車幅方向に移動させることができ、その移動する車幅方向適宜位置にて位置決めナット３９を締結することで、衝撃吸収体２３の下端２３ｂを車幅方向適宜位置にてロアアーム３に取り付けることが可能になる。なお、ガイドレール３３としてボールベアリング式のものを使用することで、すべり抵抗が小さくなって移動作業が容易となる。   By rotating the slide bolt 35 described above, the lower bracket 29 can be moved in the vehicle width direction along the guide rail 33, and the positioning nut 39 is fastened at an appropriate position in the moving vehicle width direction. The lower end 23b of the shock absorber 23 can be attached to the lower arm 3 at an appropriate position in the vehicle width direction. In addition, by using a ball bearing type as the guide rail 33, the sliding resistance is reduced and the moving operation is facilitated.

上記したスライド用ボルト３５とねじ孔２９ｄと位置決めナット３９とで移動位置決め機構を構成することになる。すなわち、移動位置決め機構はスライド用ボルト３５とねじ孔２９ｄとを有している。また、取付部であるロアブラケット２９と、ガイド部であるガイドレール３３と、移動位置決め機構とによって、取付位置可変手段を構成している。   The above-described sliding bolt 35, screw hole 29d, and positioning nut 39 constitute a moving positioning mechanism. That is, the moving positioning mechanism has a slide bolt 35 and a screw hole 29d. The lower bracket 29 as the attachment portion, the guide rail 33 as the guide portion, and the movement positioning mechanism constitute attachment position variable means.

このような構造のサスペンション装置においては、操縦安定性や乗り心地性能などの車両性能確認実験を行う際に、衝撃吸収体２３がほぼ直立した図３に示す状態に対し、ロアブラケット２９を車幅方向の適宜位置に移動させて位置決めナット３９により位置決め設定することで、レバー比を変更することができる。   In the suspension device having such a structure, when the vehicle performance confirmation experiment such as the handling stability and the riding comfort performance is performed, the lower bracket 29 is disposed in the vehicle width with respect to the state shown in FIG. The lever ratio can be changed by moving to an appropriate position in the direction and setting the positioning with the positioning nut 39.

例えば、図４に示すように、図３に対しロアブラケット２９が車輪５に近づく位置に設定した場合には、図３の状態に比較して、衝撃吸収体２３のストロークが長くなる（減衰力が大きくなる）ことからレバー比が大きくなる。逆に、図３に対しロアブラケット２９が車輪５から離れる位置に設定した場合には、図３の状態に比較して、衝撃吸収体２３のストロークが短くなる（減衰力が小さくなる）ことからレバー比が小さくなる。   For example, as shown in FIG. 4, when the lower bracket 29 is set at a position closer to the wheel 5 with respect to FIG. 3, the stroke of the shock absorber 23 becomes longer than the state of FIG. Lever ratio increases. On the other hand, when the lower bracket 29 is set at a position away from the wheel 5 with respect to FIG. 3, the stroke of the shock absorber 23 is shortened (damping force is reduced) compared to the state of FIG. The lever ratio becomes small.

このように、本実施形態では、操縦安定性や乗り心地性能の車両性能確認実験を行う際に、複数のコイルスプリングやショックアブソーバを用意する必要がなく、衝撃吸収体２３の下端２３ｂをロアアーム３に対して車幅方向に移動位置決め設定すればよく、車両開発コストを低減することができる。   As described above, in the present embodiment, it is not necessary to prepare a plurality of coil springs and shock absorbers when performing vehicle performance confirmation experiments for steering stability and riding comfort performance, and the lower end 23b of the shock absorber 23 is connected to the lower arm 3. On the other hand, it is only necessary to set the movement in the vehicle width direction, and the vehicle development cost can be reduced.

また本実施形態では、移動位置決め機構によって、ロアブラケット２９をガイドレール３３に沿って移動させた後、その移動位置にて位置決めすることができる。   In the present embodiment, the lower bracket 29 can be moved along the guide rail 33 by the movement positioning mechanism and then positioned at the movement position.

この際本実施形態では、スライド用ボルト３５をねじ孔２９ｄに対して回転させるという、極めて簡素化した構造でレバー比を容易に変更することができる。   At this time, in this embodiment, the lever ratio can be easily changed with a very simplified structure in which the slide bolt 35 is rotated with respect to the screw hole 29d.

また、上記したサスペンション装置は、ダブルウィッシュボーン式サスペンションとしてそのロアアーム３に、衝撃吸収体２３の下端２３ｂを取付位置可変手段を介して連結することで、レバー比を容易に変更することができる。   Further, in the above suspension device, the lever ratio can be easily changed by connecting the lower end 23b of the shock absorber 23 to the lower arm 3 as a double wishbone type suspension via the attachment position variable means.

なお、上記実施形態では、ロアアーム３をサスペンションメンバ１１に取り付けているが、ロアアーム３をサイドメンバ９に直接取り付ける構成としてもよい。   In the above embodiment, the lower arm 3 is attached to the suspension member 11, but the lower arm 3 may be directly attached to the side member 9.

図５は、本発明の第２の実施形態を示す自動車のサスペンション装置の、前記図３に対応する正面図である。第２の実施形態は、前記した第１の実施形態におけるロアアーム３上に、図５に示すように正面から見てほぼ直角三角形状の取付台４１を取り付け、この取付台４１上に、ガイドレール３３及び、スライド用ボルト３５を備えるブラケット３７を設置している。   FIG. 5 is a front view corresponding to FIG. 3 of the suspension device for an automobile showing the second embodiment of the present invention. In the second embodiment, a mounting base 41 having a substantially right triangle shape as viewed from the front as shown in FIG. 5 is mounted on the lower arm 3 in the first embodiment described above, and a guide rail is mounted on the mounting base 41. 33 and a bracket 37 having slide bolts 35 are installed.

取付台４１は、上記した直角三角形状部分の底面４１ａをロアアーム３上に固定し、直立する側面４１ｂを車幅方向内側に位置させ、これにより上部に位置する斜面４１ｃを、車幅方向内側（図５中で左側）が鉛直方向上方で、車幅方向外側（図５中で右側）が鉛直方向下方となるよう傾斜させている。その他の構成は、前記した第１の実施形態と同様である。   The mounting base 41 fixes the bottom surface 41a of the right-angled triangular portion on the lower arm 3 and positions the upstanding side surface 41b on the inner side in the vehicle width direction. Inclination is such that the left side in FIG. 5 is vertically upward and the outside in the vehicle width direction (right side in FIG. 5) is vertically downward. Other configurations are the same as those of the first embodiment.

前記した第１の実施形態では、衝撃吸収体２３の下端２３ｂのロアブラケット２９を、車幅方向の適宜位置に移動させて位置決め設定したときに、例えば前記した図４のように、図２に対しロアブラケット２９が車輪５に近づく位置としてレバー比を大きくした場合には、サスペンションを構成するばね系が硬くなって、車両姿勢として車高が高くなる傾向になる。   In the first embodiment described above, when the lower bracket 29 at the lower end 23b of the shock absorber 23 is moved and set to an appropriate position in the vehicle width direction, for example, as shown in FIG. On the other hand, when the lever ratio is increased as the position where the lower bracket 29 approaches the wheel 5, the spring system constituting the suspension becomes harder and the vehicle height tends to increase as the vehicle posture.

逆に、図２に対しロアブラケット２９が車輪５から離れる位置に設定してレバー比を小さくした場合には、サスペンションを構成するばね系が柔らかくなって、車両姿勢として車高が低くなる傾向になる。   On the other hand, when the lever ratio is reduced by setting the lower bracket 29 away from the wheel 5 with respect to FIG. 2, the spring system constituting the suspension becomes soft and the vehicle height tends to decrease as the vehicle posture. Become.

このような車両姿勢の変化を防ぐために、第２の実施形態では、ロアアーム３上に斜面４１ｃを有する取付台４１を設けることで、ロアブラケット２９のロアアーム３に対する取付高さ位置（鉛直方向位置）を、車幅方向内側ほど高くなるようにしている。   In order to prevent such a change in the vehicle posture, in the second embodiment, a mounting base 41 having an inclined surface 41c on the lower arm 3 is provided, whereby the mounting height position (vertical direction position) of the lower bracket 29 with respect to the lower arm 3 is provided. Is made higher toward the inner side in the vehicle width direction.

すなわち、ロアブラケット２９のロアアーム３に対する取付位置が車幅方向内側の場合には、取付位置が車幅方向外側の場合に比較して車高が低くなる傾向にあるので、取付高さ位置が車幅方向外側よりも上方となるようにして、車高が低くなるのを抑制し、車幅方向の取付位置によらず車高がほぼ一定となるようにしている。   That is, when the mounting position of the lower bracket 29 with respect to the lower arm 3 is on the inner side in the vehicle width direction, the vehicle height tends to be lower than when the mounting position is on the outer side in the vehicle width direction. The vehicle height is controlled to be lower than the outer side in the width direction, and the vehicle height is substantially constant regardless of the mounting position in the vehicle width direction.

以上より、ロアブラケット２９のロアアーム３に対する取付位置を車幅方向に変化させても、車両姿勢の変化を抑制することができる。なお、斜面４１ｃの傾斜角度θについては、車幅方向の取付位置の変化によって車高がほぼ同等となるような角度に設定している。   As described above, even if the attachment position of the lower bracket 29 to the lower arm 3 is changed in the vehicle width direction, the change in the vehicle posture can be suppressed. Note that the inclination angle θ of the inclined surface 41c is set to an angle at which the vehicle height becomes substantially equal due to the change in the mounting position in the vehicle width direction.

なお、上記した各実施形態では、衝撃吸収体２３として、コイルスプリング２５とショックアブソーバ２７とを一体化したものを使用しているが、コイルスプリングとショックアブソーバとを別々に設けた構造についても、本発明を適用することができる。その場合には、コイルスプリングとショックアブソーバとの少なくともいずれか一方の下端にロアブラケット２９を設けてロアアーム３側のガイドレール３３に対して移動可能とすればよい。   In each of the above-described embodiments, the shock absorber 23 uses an integrated coil spring 25 and shock absorber 27. However, the structure in which the coil spring and the shock absorber are separately provided is also used. The present invention can be applied. In that case, a lower bracket 29 may be provided at the lower end of at least one of the coil spring and the shock absorber so as to be movable with respect to the guide rail 33 on the lower arm 3 side.

また、スライド用ボルト３５を回転させる際に、サーボモータなどの駆動手段を使用してもよい。   Further, when the slide bolt 35 is rotated, a driving means such as a servo motor may be used.
