Description

本発明は、車輪を個別に懸架する独立懸架装置、特に、車両床下スペースの節約を可能にする車輪独立懸架装置に関するものである。   The present invention relates to an independent suspension device for individually suspending a wheel, and more particularly to a wheel independent suspension device that enables a space under the vehicle floor to be saved.

車輪独立懸架装置としては従来、例えば特許文献1に記載のごとく、車輪を回転自在に支持したアクスル部材を、車両前後方向に延在するトレーリングメンバ(特許文献1ではスイングアーム)によりトー方向に拘束し、車幅方向に車体床下まで延在する上下各1本のラテラルリンク(特許文献1ではアッパーリンクおよびロアーリンク)により車幅方向に拘束して、車両上下方向にバウンド、リバウンドし得るよう支持した構成のものが提案されている。
特開平10−076826号公報
Conventionally, as described in Patent Document 1, for example, as an independent wheel suspension apparatus, an axle member that rotatably supports a wheel is moved in a toe direction by a trailing member (a swing arm in Patent Document 1) that extends in the vehicle front-rear direction. The vehicle is restrained and restrained in the vehicle width direction by one lateral link (upper link and lower link in Patent Document 1) each extending up and down to the vehicle body floor direction so that it can bounce and rebound in the vehicle vertical direction. A supported configuration has been proposed.
JP-A-10-0776826

しかし、上記のものに代表される従来の独立懸架装置にあっては何れも、アクスル部材から車幅方向内方へ車体床下まで延在するラテラルリンクを用いてアクスル部材を車幅方向に拘束する構成を踏襲するため、以下の問題を生ずる。   However, in any of the conventional independent suspensions represented by the above, the axle member is restrained in the vehicle width direction by using a lateral link extending from the axle member inward in the vehicle width direction to the vehicle body floor. Following the configuration causes the following problems.

つまり、車幅方向内方へ車体床下まで延在するラテラルリンクはアクスル部材(車輪)のバウンド、リバウンド時に、車体側取り付け点を枢支点として上下方向に揺動するものであり、この揺動のためのスペースを車体床下に確保する必要があり、これによる車体床下の車室内への張り出し分だけ車室内空間が犠牲になって、ゆとりのある乗員空間を確保し難くなるという問題を生ずる。   In other words, the lateral link that extends inward in the vehicle width direction to the bottom of the vehicle body swings up and down around the vehicle body side attachment point when the axle member (wheel) bounces and rebounds. Therefore, it is necessary to secure a space for the vehicle body under the vehicle body floor, and this causes a problem that the vehicle interior space is sacrificed by the amount of overhanging the vehicle body floor under the vehicle body floor, making it difficult to secure a spacious passenger space.

本発明は、上記の問題がとりもなおさず、アクスル部材を車幅方向に拘束するに際しアクスル部材から車幅方向内方へ延在するラテラルリンクを用いることに起因するとの事実認識に基づき、アクスル部材から車幅方向内方へ延在する部材を必要としない独立懸架装置を提案し、これにより上記の問題を解消することを目的とする。   The present invention is based on the fact that the above problem is not solved and the fact that a lateral link extending inward in the vehicle width direction from the axle member is used when restraining the axle member in the vehicle width direction is used. The object is to propose an independent suspension device that does not require a member extending inward in the vehicle width direction from the member, thereby eliminating the above-mentioned problems.

この目的のため本発明による車輪独立懸架装置は、請求項1に記載のごとくに構成する。
つまり、1組の相互に特定方向へ相対変位可能なガイド部材より成る案内手段を、当該特定方向が車両の上下方向となるよう配置して設ける。
この案内手段は更に、上記1組のガイド部材が少なくとも車幅方向の相対位置を拘束されるような構成とする。
そして、上記1組のガイド部材のうち一方のガイド部材を少なくとも車幅方向に拘束して車体に連結し、
車輪を回転自在に支持するアクスル部材を他方のガイド部材に連結したものである。
For this purpose, the wheel independent suspension according to the invention is constructed as described in claim 1.
In other words, a pair of guide means composed of guide members that can be displaced relative to each other in a specific direction are provided so that the specific direction is the vertical direction of the vehicle.
The guide means is further configured such that the set of guide members is restrained at least in the relative position in the vehicle width direction.
And one guide member of the set of guide members is constrained at least in the vehicle width direction and connected to the vehicle body,
An axle member that rotatably supports a wheel is connected to the other guide member.

かかる本発明の構成によれば、案内手段が、アクスル部材から車幅方向内方へ延在する部材を要することなくアクスル部材を、車幅方向に拘束して上下動可能に案内し得ることから、
車幅方向内方へ延在する部材の揺動スペースを車体床下に確保する必要がなくて、車体床下が車室内へ張り出すこともないため、車室内空間が犠牲になって十分な乗員空間を確保し難くなるという前記した従来装置の問題を解消することができる。
According to such a configuration of the present invention, the guide means can guide the axle member so as to move up and down by restraining it in the vehicle width direction without requiring a member extending inward in the vehicle width direction from the axle member. ,
There is no need to secure a rocking space for the members extending inward in the vehicle width direction under the vehicle body floor, and the vehicle body floor does not protrude into the vehicle interior. It is possible to solve the above-described problem of the conventional apparatus that it is difficult to ensure the above.

以下、本発明の実施の形態を、図面に示す実施例に基づき詳細に説明する。
図1は、本発明の一実施例になる車輪独立懸架装置の要部を車両側面から見て示し、これを本実施例においては、後輪用の独立懸架装置として用いるのに有用な以下の構成となす。
Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings.
FIG. 1 shows a main part of a wheel independent suspension device according to an embodiment of the present invention as viewed from the side of a vehicle. In this embodiment, the following is useful as an independent suspension device for a rear wheel. With composition.

図において1は、本発明における案内手段を成すショックアブソーバを示し、このショックアブソーバ1を図2に明示するごとく、シリンダ2と、これに摺動自在に嵌合したピストン3と、このピストン3に結合したロッド4とで構成する。
シリンダ2およびロッド4はシリンダ2の軸線方向に相対変位可能であるが、シリンダ2の軸線を横切る面内における全ての方向における相対位置を拘束され、本発明におけるガイド部材を構成する。
ロッド4は、ピストン3の両側においてシリンダ2内に画成された液封シリンダ室5,6を貫通し、シリンダ2の両端部から抜き差し可能に突出させる。
In the figure, reference numeral 1 denotes a shock absorber which constitutes a guiding means in the present invention. As clearly shown in FIG. 2, the shock absorber 1 is a cylinder 2, a piston 3 slidably fitted thereto, and a piston 3. It is composed of the coupled rods 4.
Although the cylinder 2 and the rod 4 can be relatively displaced in the axial direction of the cylinder 2, the relative positions in all directions in a plane crossing the axial line of the cylinder 2 are constrained to constitute a guide member in the present invention.
The rod 4 passes through the liquid-sealed cylinder chambers 5 and 6 defined in the cylinder 2 on both sides of the piston 3 and protrudes from both ends of the cylinder 2 so as to be inserted and removed.

ピストン3には連通孔7,8を穿設し、これらピストン連通孔7,8をピストン3の相互に逆の側から塞ぐ弾性弁体9,10を設け、これらで、以下のように作動する振動減衰弁を構成する。
ピストン3がシリンダ2に対し相対的に図2の上方へ変位するストローク時は、シリンダ室5内の作動液が弾性弁体10を押しのけつつ連通孔8を経てシリンダ室6に流入し、この時の作動液の流動抵抗で振動減衰機能が得られ、逆にピストン3がシリンダ2に対し相対的に図2の下方へ変位するストローク時は、シリンダ室6内の作動液が弾性弁体9を押しのけつつ連通孔7を経てシリンダ室5に流入し、この時の作動液の流動抵抗で振動減衰機能が得られる。
The piston 3 is provided with communication holes 7 and 8, and elastic valve bodies 9 and 10 are provided to close the piston communication holes 7 and 8 from the opposite sides of the piston 3, and operate as follows. A vibration damping valve is configured.
During the stroke in which the piston 3 is displaced upward in FIG. 2 relative to the cylinder 2, the hydraulic fluid in the cylinder chamber 5 flows into the cylinder chamber 6 through the communication hole 8 while pushing the elastic valve body 10. In the stroke in which the piston 3 is displaced relative to the cylinder 2 in the downward direction of FIG. 2, the hydraulic fluid in the cylinder chamber 6 causes the elastic valve body 9 to move. While pushing, it flows into the cylinder chamber 5 through the communication hole 7, and the vibration damping function is obtained by the flow resistance of the hydraulic fluid at this time.

かかるショックアブソーバ1を図1に示すごとく、シリンダ2およびロッド4の相対変位方向が車両上下方向となるよう配置して設けるが、車両制動時のノーズダイブ現象(車両前方が車高低下する現象)を緩和するアンチダイブ性が得られる後輪変位を惹起するようショックアブソーバ1は、上端が下端よりも車両後方に位置するよう後傾させる。
この姿勢でショックアブソーバ1は、シリンダ2の両端部から突出するロッド4の両端をそれぞれ車体11に結合して車両前後方向および車幅方向に拘束し、他方でシリンダ2には、ブラケット12を介してアクスル部材13を結合する。
アクスル部材13は、後輪(図示せず)を回転自在に支持するためのもので、後輪の回転中心をOで例示した。
As shown in FIG. 1, the shock absorber 1 is arranged so that the relative displacement direction of the cylinder 2 and the rod 4 is the vehicle vertical direction. However, a nose dive phenomenon during vehicle braking (a phenomenon in which the vehicle front lowers the vehicle height). The shock absorber 1 is tilted rearward so that the upper end is positioned behind the lower end of the vehicle so as to induce rear wheel displacement that provides anti-dive properties that alleviate the above.
In this posture, the shock absorber 1 couples both ends of the rod 4 protruding from both ends of the cylinder 2 to the vehicle body 11 to restrain the vehicle 2 in the vehicle front-rear direction and the vehicle width direction. Then, the axle member 13 is coupled.
The axle member 13 is for rotatably supporting a rear wheel (not shown), and the rotation center of the rear wheel is illustrated by O.

図3に示す実施例では、ショックアブソーバ1を2個のシリンダ2a,2bと、これらシリンダ内に摺動自在に嵌合した2個のピストン3a,3bと、これらピストンに固設した2個のロッド4a,4bとで構成する。
ロッド4aを対応するシリンダ2aの一端部より抜き差し可能に突出させ、ロッド4bを対応するシリンダ2bの一端部より抜き差し可能に突出させ、これらシリンダ2a,2bの他端部同士を同軸に結合させる。
なお各ピストン3a,3bには、図2につき前述したピストン連通孔7,8および弾性弁体9,10より成る振動減衰弁と同様な振動減衰弁を設けることは言うまでもない。
図3のショックアブソーバ1も図1に示すと同様の姿勢で配置し、ロッド4aの突出先端およびロッド4bの突出先端をそれぞれ車体11に結合して実用することができる。
The shock absorber 1 constituting the guide means of the axle member 13 may be configured as shown in FIG. 3 or 4 in addition to the configuration shown in FIG.
In the embodiment shown in FIG. 3, the shock absorber 1 has two cylinders 2a and 2b, two pistons 3a and 3b slidably fitted in these cylinders, and two pistons fixed to these pistons. It comprises rods 4a and 4b.

Needless to say, each of the pistons 3a and 3b is provided with a vibration damping valve similar to the vibration damping valve composed of the piston communication holes 7 and 8 and the elastic valve bodies 9 and 10 described above with reference to FIG.
The shock absorber 1 shown in FIG. 3 is also arranged in the same posture as shown in FIG. 1 and can be put into practical use by connecting the protruding tip of the rod 4a and the protruding tip of the rod 4b to the vehicle body 11, respectively.

図4に示す実施例でも、ショックアブソーバ1を2個のシリンダ2a,2bと、これらシリンダ内に摺動自在に嵌合した2個のピストン3a,3bと、これらピストンに固設した2個のロッド4a,4bとで構成する。
そして、ロッド4aを対応するシリンダ2aの一端部より抜き差し可能に突出させ、ロッド4bを対応するシリンダ2bの一端部より抜き差し可能に突出させるが、これらシリンダ2a,2b同士を、それぞれのロッド4a,4bが相互逆向きに指向するよう横並びにして結合する。
なお各ピストン3a,3bには、図2につき前述したピストン連通孔7,8および弾性弁体9,10より成る振動減衰弁と同様な振動減衰弁を設けることは言うまでもない。
図4のショックアブソーバ1も図1に示すと同様の姿勢で配置し、ロッド4aの突出先端およびロッド4bの突出先端をそれぞれ車体11に結合して実用することができる。
Also in the embodiment shown in FIG. 4, the shock absorber 1 has two cylinders 2a and 2b, two pistons 3a and 3b slidably fitted in these cylinders, and two pistons fixed to these pistons. It comprises rods 4a and 4b.
Then, the rod 4a is protruded from one end of the corresponding cylinder 2a so that it can be inserted and removed, and the rod 4b is protruded from the corresponding end of the cylinder 2b so that the rod 4a can be inserted and removed. 4b are connected side by side so that they are directed in opposite directions.
Needless to say, each of the pistons 3a and 3b is provided with a vibration damping valve similar to the vibration damping valve composed of the piston communication holes 7 and 8 and the elastic valve bodies 9 and 10 described above with reference to FIG.
The shock absorber 1 shown in FIG. 4 is also arranged in the same posture as shown in FIG. 1, and can be put into practical use by connecting the protruding tip of the rod 4a and the protruding tip of the rod 4b to the vehicle body 11, respectively.

アクスル部材13をトー方向に拘束する構成は、図5〜図10に例示するようなものとすることができる。
図5の例では、アクスル部材13をトー方向に拘束するトレーリングメンバとして板バネ14を設け、これを車両前後方向においてアクスル部材13および車体11間に延在させる。
板バネ14の前端はブラケット15を介して車体11に剛結合し、板バネ14の後端はシャックル16を介してアクスル部材13に連結し、かくして板バネ14によりアクスル部材13をトー方向に拘束するようになす。
かように、アクスル部材13をトー方向に拘束するトレーリングメンバを板バネ14で構成する場合、トレーリングメンバ(板バネ14)にサスペンションスプリングの機能をも持たせることができる。
The configuration for restraining the axle member 13 in the toe direction can be as illustrated in FIGS.
In the example of FIG. 5, a leaf spring 14 is provided as a trailing member that restrains the axle member 13 in the toe direction, and extends between the axle member 13 and the vehicle body 11 in the vehicle longitudinal direction.
The front end of the leaf spring 14 is rigidly connected to the vehicle body 11 via the bracket 15, and the rear end of the leaf spring 14 is connected to the axle member 13 via the shackle 16, thus restraining the axle member 13 in the toe direction by the leaf spring 14. To do.
Thus, when the trailing member that restrains the axle member 13 in the toe direction is configured by the leaf spring 14, the trailing member (plate spring 14) can also have a suspension spring function.

図6の例では、アクスル部材13をトー方向に拘束するトレーリングメンバとして、同様に車両前後方向に延在するようアクスル部材13および車体11間に架設した板バネ14を用いるが
この板バネ14を、前端においては2個のシャックル17,18を介して車体11に連結し、後端においてはピン19を介してアクスル部材13に連結する。
In the example of FIG. 6, a leaf spring 14 is used as a trailing member that restrains the axle member 13 in the toe direction, and is similarly extended between the axle member 13 and the vehicle body 11 so as to extend in the vehicle longitudinal direction. Is connected to the vehicle body 11 through two shackles 17 and 18 at the front end, and is connected to the axle member 13 through a pin 19 at the rear end.

図7の例では、アクスル部材13をトー方向に拘束するトレーリングメンバとして、同様に車両前後方向に延在するようアクスル部材13および車体11間に架設した板バネ14を用いるが
この板バネ14を、前端においては1個のシャックル20を介して車体11に連結し、後端においてはブラケット21を介してアクスル部材13に剛結合する。
In the example of FIG. 7, a leaf spring 14 is used as a trailing member that restrains the axle member 13 in the toe direction. The leaf spring 14 is installed between the axle member 13 and the vehicle body 11 so as to extend in the vehicle longitudinal direction. Are connected to the vehicle body 11 through a single shackle 20 at the front end and rigidly connected to the axle member 13 through a bracket 21 at the rear end.

図8の例では、アクスル部材13をトー方向に拘束するトレーリングメンバとして、同様に車両前後方向に延在するようアクスル部材13および車体11間に架設した板バネ14を用いるが
この板バネ14を、前端においてはピン22を介して車体11に連結し、後端においては2個のシャックル23,24を介してアクスル部材13に連結する。
In the example of FIG. 8, a leaf spring 14 is used as a trailing member that restrains the axle member 13 in the toe direction. The leaf spring 14 is installed between the axle member 13 and the vehicle body 11 so as to extend in the vehicle longitudinal direction. Is connected to the vehicle body 11 via a pin 22 at the front end and to the axle member 13 via two shackles 23 and 24 at the rear end.

図9の例では、アクスル部材13をトー方向に拘束するトレーリングメンバとしてリンク25を設け、これを車両前後方向においてアクスル部材13および車体11間に延在させる。
リンク25の前端は1個のシャックルを介して車体11に連結し、リンク25の後端はピン27を介してアクスル部材13に連結し、かくしてリンク25によりアクスル部材13をトー方向に拘束するようになす。
かように、アクスル部材13をトー方向に拘束するトレーリングメンバをリンク25で構成する場合、トレーリングメンバ(リンク25)にサスペンションスプリングの機能を持たせることができないため、リンク25と車体11との間にサスペンションスプリング機能を有するコイルスプリング28を架設する。
In the example of FIG. 9, a link 25 is provided as a trailing member that restrains the axle member 13 in the toe direction, and extends between the axle member 13 and the vehicle body 11 in the vehicle longitudinal direction.
The front end of the link 25 is connected to the vehicle body 11 via a single shackle, and the rear end of the link 25 is connected to the axle member 13 via a pin 27. Thus, the axle 25 is restrained by the link 25 in the toe direction. To make.
In this way, when the trailing member that restrains the axle member 13 in the toe direction is configured by the link 25, the trailing member (link 25) cannot have the function of a suspension spring. A coil spring 28 having a suspension spring function is installed between the two.

図10の例では、アクスル部材13をトー方向に拘束するトレーリングメンバとして、同様に車両前後方向に延在するようアクスル部材13および車体11間に架設したリンク25を用いるが、
リンク25の前端を、車幅方向に横置きしたトーションバー29の外端に結合し、該トーションバー29の内端を車体11に結合する。
そして、リンク25の後端を1個のシャックル30を介してアクスル部材13に連結し、リンク25によりアクスル部材13をトー方向に拘束するようになす。
本例では、アクスル部材13の上下動によりリンク25がトーションバー29の外端に回転力を伝達し、この回転力を受けてトーションバー29が、車体11に結合されている内端を固定端として捻られることによりサスペンションスプリングの機能を果たすため、図9におけるようなコイルスプリング28が不要である。
In the example of FIG. 10, as a trailing member that restrains the axle member 13 in the toe direction, a link 25 that is installed between the axle member 13 and the vehicle body 11 so as to extend in the vehicle longitudinal direction is used.
The front end of the link 25 is coupled to the outer end of the torsion bar 29 placed horizontally in the vehicle width direction, and the inner end of the torsion bar 29 is coupled to the vehicle body 11.
Then, the rear end of the link 25 is connected to the axle member 13 through one shackle 30, and the axle member 13 is restrained in the toe direction by the link 25.
In this example, the link 25 transmits a rotational force to the outer end of the torsion bar 29 by the vertical movement of the axle member 13, and the torsion bar 29 receives the rotational force and the inner end connected to the vehicle body 11 is fixed to the fixed end. Therefore, the coil spring 28 shown in FIG. 9 is not necessary.

上記各実施例におけるシャックルの作用を、図6の構成例につき図11を参照しつつ以下に説明する。
図11(a)は、アクスル部材13が上下動していないノーマル時の状態を示し、この状態からアクスル部材13(後輪)がαで示す上方へバウンドするとき、板バネ14の後端とアクスル部材13との間における連結ピン19は図11(b)に示すように、車両後方へ変位しつつ上昇する。
かかる連結ピン19の変位に伴う板バネ14の後方変位を、シャックル17,18が矢印γで示す方向へ回動することにより吸収することができ、シャックル17,18は、板バネ14および車体11間の連結構造を車両前後方向へ変位可能な連結構造として、アクスル部材13(後輪)の上記バウンドが妨げられることのないよう機能する。
The operation of the shackle in each of the above embodiments will be described below with reference to FIG. 11 for the configuration example of FIG.
FIG. 11 (a) shows a normal state in which the axle member 13 is not moving up and down, and when the axle member 13 (rear wheel) bounces upward indicated by α from this state, As shown in FIG. 11 (b), the connecting pin 19 between the axle member 13 and the axle member 13 moves upward while being displaced rearward.
The rearward displacement of the leaf spring 14 due to the displacement of the connecting pin 19 can be absorbed by the shackles 17 and 18 rotating in the direction indicated by the arrow γ. The shackles 17 and 18 are absorbed by the leaf spring 14 and the vehicle body 11. The connecting structure between the two functions as a connecting structure that can be displaced in the vehicle front-rear direction, and functions so that the bounce of the axle member 13 (rear wheel) is not hindered.

逆にアクスル部材13(後輪)が、図11(a)に示すノーマル状態からβで示す下方へリバウンドするときは、板バネ14の後端とアクスル部材13との間における連結ピン19が図11(c)に示すように、車両前方へ変位しつつ下降する。
かかる連結ピン19の変位に伴う板バネ14の前方変位を、シャックル17,18が矢印δで示す方向へ回動することにより吸収して、アクスル部材13(後輪)の上記リバウンドを可能ならしめる。
Conversely, when the axle member 13 (rear wheel) rebounds downward from the normal state shown in FIG. 11A by β, the connecting pin 19 between the rear end of the leaf spring 14 and the axle member 13 is illustrated. 11 (c), the vehicle descends while being displaced forward of the vehicle.
The forward displacement of the leaf spring 14 due to the displacement of the connecting pin 19 is absorbed by the shackles 17 and 18 being rotated in the direction indicated by the arrow δ, thereby enabling the rebound of the axle member 13 (rear wheel). .

図12〜図14は、図1および図5の組み合わせに成る独立懸架装置を、前輪駆動車の後輪に適用した実体構成例を示す。
本実体構成例では、図2につき前述したショックアブソーバ1を図1につき前述したと同様に、シリンダ2およびロッド4の相対変位方向が車両上下方向となるよう、また、アンチダイブ性の確保のため後傾させて配置する。
該ショックアブソーバ1はアクスル部材13の案内手段を成し、シリンダ2の両端部から抜き差し可能に突出するロッド4の上端をブラケット31を介して車体11に結合し、ロッド4の下端を図13および図14に示すようにブラケット32を介して車体11に結合する。
FIGS. 12-14 show the example of a solid structure which applied the independent suspension apparatus which becomes a combination of FIG. 1 and FIG. 5 to the rear wheel of the front-wheel drive vehicle.
In this actual configuration example, the shock absorber 1 described above with reference to FIG. 2 is set so that the relative displacement direction of the cylinder 2 and the rod 4 is the vehicle vertical direction, as described above with reference to FIG. Arrange backwards.
The shock absorber 1 serves as a guide means for the axle member 13, and the upper end of the rod 4 protruding from both ends of the cylinder 2 is removably connected to the vehicle body 11 via the bracket 31. As shown in FIG. 14, it couple | bonds with the vehicle body 11 via the bracket 32. As shown in FIG.

かくて、ショックアブソーバ1(シリンダ2およびロッド4)は車体11に対し車両前後方向および車幅方向に拘束され、シリンダ2はロッド4に対しロッド4の軸線方向(車両上下方向)に相対変位することができる。
かように車両上下方向に変位可能なシリンダ2には、ブラケット12(図13および図14参照)を介してアクスル部材13を結合し、このアクスル部材13には後輪(図示せず)を回転自在に支持して、後輪を上下方向に変位可能にするが、車幅方向に拘束する。
Thus, the shock absorber 1 (cylinder 2 and rod 4) is restrained in the vehicle longitudinal direction and the vehicle width direction with respect to the vehicle body 11, and the cylinder 2 is displaced relative to the rod 4 in the axial direction of the rod 4 (vehicle vertical direction). be able to.
An axle member 13 is coupled to the cylinder 2 that can be displaced in the vertical direction of the vehicle via a bracket 12 (see FIGS. 13 and 14), and a rear wheel (not shown) is rotated on the axle member 13. The rear wheel can be displaced in the vertical direction while being supported freely, but is restrained in the vehicle width direction.

アクスル部材13はショックアブソーバ1の軸線周りでトー方向に回動可能であり、アクスル部材13を該トー方向に拘束する必要がある。
これがため本実体構成例では、図5につき前述したと同様、アクスル部材13をトー方向に拘束するトレーリングメンバとして板バネ14を設け、これを車両前後方向においてアクスル部材13および車体11間に延在させる。
車両前後方向に延在されたかかる板バネ14の前端はブラケット15を介して車体11に剛結合し、板バネ14の後端はシャックル16を介してアクスル部材13に連結し、かかる板バネ14によりアクスル部材13をトー方向に拘束する。
また、トレーリングメンバ(板バネ14)は後述するごとく、サスペンションスプリングとしても機能させる。
The axle member 13 can rotate in the toe direction around the axis of the shock absorber 1, and the axle member 13 needs to be restrained in the toe direction.
Therefore, in this example of the actual configuration, as described above with reference to FIG. 5, the leaf spring 14 is provided as a trailing member for restraining the axle member 13 in the toe direction, and this is extended between the axle member 13 and the vehicle body 11 in the vehicle longitudinal direction. Let it be.
The front end of the leaf spring 14 extending in the longitudinal direction of the vehicle is rigidly coupled to the vehicle body 11 via the bracket 15, and the rear end of the leaf spring 14 is connected to the axle member 13 via the shackle 16. Thus, the axle member 13 is restrained in the toe direction.
The trailing member (leaf spring 14) also functions as a suspension spring, as will be described later.

本実体構成例になる独立懸架装置の作用を次に説明する。
アクスル部材13(後輪)は、バウンド、リバウンド時、ショックアブソーバ1により案内されて図1にα,βで示すショックアブソーバ軸線方向に例えば一点鎖線位置や破線位置に上下動し、同時にショックアブソーバ1により上下方向のストローク振動を減衰される。
この間、板バネ14はアクスル部材13(後輪)のトー方向位置を拘束し、無用な後輪のトー角の変化を防止する。
板バネ14は更に、自己のバネ作用下にアクスル部材13(後輪)のバウンド、リバウンドを行わせ、サスペンションスプリングとして所定の緩衝機能をも果たす。
Next, the operation of the independent suspension apparatus according to this example of the actual configuration will be described.
The axle member 13 (rear wheel) is guided by the shock absorber 1 during bounding and rebounding and moves up and down in the direction of the shock absorber axis indicated by α and β in FIG. Thus, the vertical stroke vibration is attenuated.
During this time, the leaf spring 14 restrains the position of the axle member 13 (rear wheel) in the toe direction to prevent useless changes in the toe angle of the rear wheel.
The leaf spring 14 further causes the axle member 13 (rear wheel) to bounce and rebound under its own spring action, and also fulfills a predetermined buffer function as a suspension spring.

一方でアクスル部材13(後輪)は、そのバウンド、リバウンド時、図11につき前述したごとく車両前後方向の変位を伴って上下動し、板バネ14に対して干渉しようとする。
しかしこの時シャックル16が、図11につき前述したシャックル17,18と同様に機能(回動)して、アクスル部材13(後輪)のバウンド、リバウンド時における前後方向変位を吸収し得るため、アクスル部材13(後輪)の前後方向変位を伴ったバウンド、リバウンドが板バネ14によって妨げられることはない。
On the other hand, the axle member 13 (rear wheel) moves up and down with displacement in the vehicle front-rear direction as described above with reference to FIG.
However, at this time, the shackle 16 functions (rotates) in the same manner as the shackles 17 and 18 described above with reference to FIG. 11, and can absorb the displacement in the front-rear direction when the axle member 13 (rear wheel) bounces and rebounds. The bounce and rebound accompanied by the longitudinal displacement of the member 13 (rear wheel) is not hindered by the leaf spring 14.

ところで本実体構成例になる独立懸架装置によれば、アクスル部材13(後輪)の案内手段を成すショックアブソーバ1を、そのストローク方向が車両の上下方向となるよう配置して設け、
該ショックアブソーバ1を成すロッド4を、車両前後方向および車幅方向に拘束して車体11に連結し、
ショックアブソーバ1を成すシリンダ2にアクスル部材13(後輪)を連結した構成になるから、
上下方向に延在するショックアブソーバ1が、それ単独でアクスル部材13(後輪)を車幅方向に拘束し、従来のようにアクスル部材13から車幅方向内方へ延在する部材を要することなく、アクスル部材13(後輪)を車幅方向に拘束して上下動可能に案内することとなり、
車幅方向内方へ延在する部材の揺動スペースを車体床下に確保する必要がなくて、車体床下が車室内へ張り出すこともないので、車室内空間が犠牲になって十分な乗員空間を確保し難くなるという従来装置の前記した問題を解消することができる。
By the way, according to the independent suspension device according to the present configuration example, the shock absorber 1 that constitutes the guide means of the axle member 13 (rear wheel) is provided so that its stroke direction is the vertical direction of the vehicle,
The rod 4 constituting the shock absorber 1 is constrained in the vehicle longitudinal direction and the vehicle width direction and coupled to the vehicle body 11,
Since the axle member 13 (rear wheel) is connected to the cylinder 2 constituting the shock absorber 1,
The shock absorber 1 extending in the vertical direction needs to restrain the axle member 13 (rear wheel) in the vehicle width direction by itself, and requires a member extending inward in the vehicle width direction as in the prior art. Without restricting the axle member 13 (rear wheel) in the vehicle width direction, it will be guided to move up and down.
Since there is no need to secure a swinging space for the members extending inward in the vehicle width direction under the vehicle body floor and the vehicle body floor does not protrude into the vehicle interior, sufficient passenger space is sacrificed at the expense of vehicle interior space. It is possible to solve the above-mentioned problem of the conventional apparatus that it is difficult to ensure the above.

また、アクスル部材13(後輪)を車幅方向に拘束するための、車幅方向内方へ延在する部材が必要でないということは、それだけ部品点数の減少によりコスト上、および重量の点でも有利になることを意味する。   In addition, the fact that a member extending inward in the vehicle width direction for restraining the axle member 13 (rear wheel) in the vehicle width direction is not necessary means that in terms of cost and weight, the number of parts is reduced accordingly. It means to be advantageous.

ところで本実体構成例になる独立懸架装置によれば、アクスル部材13(後輪)の上記案内を司るショックアブソーバ1を、図2に明示するごとく1個のシリンダ2と、これに貫通させてシリンダ両端部から突出する1本のロッド4とを有する構成としたから、
ショックアブソーバ1を図3や図4のように2個のシリンダ2a,2bおよび2本のロッド4a,4bを有する構成にする場合よりも強度上有利である。
なお図12〜図14の実体構成例では、シリンダ2両端部から突出する1本のロッド4の両端を共に車体11に結合したから、車体11に対するショックアブソーバ1の取り付け剛性が高くなるが、この取り付け剛性の要求程度によっては、ロッド4の一端のみを車体に結合するようにしてもよいことは言うまでもない。
この場合ショックアブソーバ1は、ロッドがシリンダの一端部のみから突出する一般的なショックアブソーバでよいことは勿論である。
By the way, according to the independent suspension device according to the present real configuration example, the shock absorber 1 that controls the above-mentioned guidance of the axle member 13 (rear wheel) is made to pass through one cylinder 2 and the cylinder as shown in FIG. Since it was set as the structure which has one rod 4 which protrudes from both ends,
The shock absorber 1 is advantageous in terms of strength as compared with the case where the shock absorber 1 has two cylinders 2a and 2b and two rods 4a and 4b as shown in FIGS.
12 to 14, since both ends of one rod 4 protruding from both ends of the cylinder 2 are coupled to the vehicle body 11, the mounting rigidity of the shock absorber 1 to the vehicle body 11 is increased. It goes without saying that only one end of the rod 4 may be coupled to the vehicle body depending on the required degree of mounting rigidity.
In this case, the shock absorber 1 may be a general shock absorber in which the rod protrudes from only one end of the cylinder.

図15〜図17は、図1および図6の組み合わせに成る独立懸架装置を、前輪駆動車の後輪に適用した実体構成例を示す。
本実体構成例でも、図2につき前述したショックアブソーバ1を図12〜図14におけると同様、車両上下方向に延在させて、また、アンチダイブ性の確保のため後傾させて配置し、
シリンダ2の両端部から抜き差し可能に突出するロッド4の上端をブラケット31を介して車体11に結合し、ロッド4の下端を図16および図17に示すようにブラケット32を介して車体11に結合する。
FIGS. 15 to 17 show an example of an actual configuration in which the independent suspension device having the combination of FIGS. 1 and 6 is applied to the rear wheels of a front-wheel drive vehicle.
Also in this actual configuration example, the shock absorber 1 described above with reference to FIG. 2 is extended in the vehicle vertical direction as in FIGS. 12 to 14, and is tilted rearward to ensure anti-dive properties,
The upper end of the rod 4 that protrudes from both ends of the cylinder 2 is coupled to the vehicle body 11 via a bracket 31, and the lower end of the rod 4 is coupled to the vehicle body 11 via a bracket 32 as shown in FIGS. To do.

ショックアブソーバ1(シリンダ2およびロッド4)は車体11に対し前後方向および車幅方向に拘束され、シリンダ2はロッド4に対し軸線方向(車両上下方向)に相対変位することができる。
かように車両上下方向に変位可能なシリンダ2には、ブラケット12を介してアクスル部材13を結合し、このアクスル部材13には後輪(図示せず)を回転自在に支持して、後輪を上下方向に変位可能にするが、車幅方向に拘束する。
The shock absorber 1 (cylinder 2 and rod 4) is restrained in the front-rear direction and the vehicle width direction with respect to the vehicle body 11, and the cylinder 2 can be relatively displaced with respect to the rod 4 in the axial direction (vehicle vertical direction).
An axle member 13 is coupled to the cylinder 2 that can be displaced in the vertical direction of the vehicle via a bracket 12, and a rear wheel (not shown) is rotatably supported on the axle member 13. Can be displaced in the vertical direction, but is restricted in the vehicle width direction.

アクスル部材13はショックアブソーバ1の軸線周りでトー方向に回動可能であり、アクスル部材13を該トー方向に拘束する必要がある。
これがため本実体構成例では、図6につき前述したと同様、アクスル部材13をトー方向に拘束するトレーリングメンバとして板バネ14を設け、これを車両前後方向においてアクスル部材13および車体11間に延在させる。
車両前後方向に延在されたかかる板バネ14の前端はシャックル17,18を介して車体11に連結し、板バネ14の後端はピン17を介してアクスル部材13に連結し、かかる板バネ14によりアクスル部材13をトー方向に拘束する。
The axle member 13 can rotate in the toe direction around the axis of the shock absorber 1, and the axle member 13 needs to be restrained in the toe direction.
For this reason, in this example of the actual configuration, a leaf spring 14 is provided as a trailing member for restraining the axle member 13 in the toe direction as described above with reference to FIG. 6, and this is extended between the axle member 13 and the vehicle body 11 in the vehicle front-rear direction. Let it be.
The front end of the leaf spring 14 extending in the vehicle front-rear direction is connected to the vehicle body 11 via shackles 17 and 18, and the rear end of the leaf spring 14 is connected to the axle member 13 via the pin 17. 14, the axle member 13 is restrained in the toe direction.

本実体構成例になる独立懸架装置も、図12〜図14に示す実態構成例と同様に作用して、同様の作用効果を達成することができる。
しかし本実体構成例では、アクスル部材13(後輪)のバウンド、リバウンド時における車両前後方向変位を、シャックル17,18が、図11につき前述した回動γ,δにより吸収する点が、図12〜図14に示す実態構成例と異なる。
The independent suspension device according to the present configuration example can also operate in the same manner as the actual configuration example illustrated in FIGS. 12 to 14 and achieve the same operational effects.
However, in this actual configuration example, the shackles 17 and 18 absorb the displacement in the longitudinal direction of the vehicle when the axle member 13 (rear wheel) bounces and rebounds by the rotations γ and δ described above with reference to FIG. ~ Different from the actual configuration example shown in FIG.

図18〜図20は、前輪駆動車の後輪に適用した更に他の実体構成例を示す。
本実体構成例でも、図2につき前述したショックアブソーバ1を図12〜図14および図15〜図17におけると同様、車両上下方向に延在させて、また、アンチダイブ性の確保のため後傾させて配置する。
しかし本実体構成例では、シリンダ2の両端部から抜き差し可能に突出するロッド4の両端間を橋絡するブラケット33をロッド4の両端に固着し、この橋絡ブラケット33にアクスル部材13を固設する。
そして、シリンダ2をブラケット34を介して車体11に結合する。
18 to 20 show still other examples of the actual configuration applied to the rear wheels of the front-wheel drive vehicle.
Also in this example of the actual configuration, the shock absorber 1 described above with reference to FIG. 2 is extended in the vehicle vertical direction as in FIGS. 12 to 14 and 15 to 17 and is tilted backward to ensure anti-dive properties. Let them be arranged.
However, in this actual configuration example, brackets 33 that bridge between both ends of the rod 4 projecting from both ends of the cylinder 2 are fixed to both ends of the rod 4, and the axle member 13 is fixed to the bridge bracket 33. To do.
Then, the cylinder 2 is coupled to the vehicle body 11 via the bracket 34.

かくてショックアブソーバ1(シリンダ2およびロッド4)は車体11に対し前後方向および車幅方向に拘束され、ロッド4はシリンダ2に対しロッド4の軸線方向(車両上下方向)に相対変位することができる。
つまり前記各実体構成例とは逆に、シリンダ2を車体11に結合して固定し、ロッド4をアクスル部材13(後輪)のバウンド、リバウンドに伴ってこれと共に上下動させるようになすが、ロッド4をアクスル部材13(後輪)と共に車両の前後方向および車幅方向に拘束する。
Thus, the shock absorber 1 (cylinder 2 and rod 4) is restrained relative to the vehicle body 11 in the front-rear direction and the vehicle width direction, and the rod 4 can be displaced relative to the cylinder 2 in the axial direction of the rod 4 (vehicle up-down direction). it can.
That is, contrary to the above-described examples of the actual configuration, the cylinder 2 is coupled and fixed to the vehicle body 11, and the rod 4 is moved up and down together with the bound and rebound of the axle member 13 (rear wheel). The rod 4 is restrained together with the axle member 13 (rear wheel) in the vehicle front-rear direction and the vehicle width direction.

アクスル部材13(後輪)をトー方向に拘束するため本実体構成例では、図7につき前述したと同様、アクスル部材13をトー方向に拘束するトレーリングメンバとして板バネ14を設け、これを車両前後方向において橋絡ブラケット33の下端と車体11との間に延在させる。
車両前後方向に延在されるかかる板バネ14の前端はシャックル20を介して車体11に連結し、板バネ14の後端はブラケット21を介して橋絡ブラケット33の下端に剛結合し、かかる板バネ14によりアクスル部材13をトー方向に拘束する。
In the present structural example for restraining the axle member 13 (rear wheel) in the toe direction, a leaf spring 14 is provided as a trailing member for restraining the axle member 13 in the toe direction as described above with reference to FIG. It extends between the lower end of the bridge bracket 33 and the vehicle body 11 in the front-rear direction.
The front end of the leaf spring 14 extending in the longitudinal direction of the vehicle is connected to the vehicle body 11 via the shackle 20, and the rear end of the leaf spring 14 is rigidly coupled to the lower end of the bridging bracket 33 via the bracket 21. The axle member 13 is restrained in the toe direction by the leaf spring 14.

本実体構成例になる独立懸架装置の作用を次に説明する。
アクスル部材13(後輪)は、バウンド、リバウンド時、ショックアブソーバ1のシリンダ2によりロッド4および橋絡ブラケット33を介し案内されてショックアブソーバ1の軸線方向に上下動し、同時に上下方向のストローク振動をショックアブソーバ1により減衰される。
この間、板バネ14はアクスル部材13(後輪)のトー方向位置を拘束し、無用な後輪のトー角の変化を防止する。
板バネ14は更に、自己のバネ作用下にアクスル部材13(後輪)のバウンド、リバウンドを行わせ、サスペンションスプリングとして所定の緩衝機能をも果たす。
Next, the operation of the independent suspension apparatus according to this example of the actual configuration will be described.
The axle member 13 (rear wheel) is guided by the cylinder 2 of the shock absorber 1 via the rod 4 and the bridging bracket 33 during bouncing and rebounding, and moves up and down in the axial direction of the shock absorber 1 at the same time. Is attenuated by the shock absorber 1.
During this time, the leaf spring 14 restrains the position of the axle member 13 (rear wheel) in the toe direction to prevent useless changes in the toe angle of the rear wheel.
The leaf spring 14 further causes the axle member 13 (rear wheel) to bounce and rebound under its own spring action, and also fulfills a predetermined buffer function as a suspension spring.

一方でアクスル部材13(後輪)は、そのバウンド、リバウンド時、図11につき前述したごとく車両前後方向の変位を伴って上下動し、板バネ14に対して干渉しようとする。
しかしこの時シャックル20が、図11につき前述したシャックル17,18と同様に機能(回動)して、アクスル部材13(後輪)のバウンド、リバウンド時における前後方向変位を吸収し得るため、アクスル部材13(後輪)の前後方向変位を伴ったバウンド、リバウンドが板バネ14によって妨げられることはない。
On the other hand, the axle member 13 (rear wheel) moves up and down with displacement in the vehicle front-rear direction as described above with reference to FIG.
However, at this time, the shackle 20 functions (rotates) in the same manner as the shackles 17 and 18 described above with reference to FIG. 11 and can absorb the displacement in the front-rear direction when the axle member 13 (rear wheel) bounces and rebounds. The bounce and rebound accompanied by the longitudinal displacement of the member 13 (rear wheel) is not hindered by the leaf spring 14.

ところで本実体構成例になる独立懸架装置によれば、アクスル部材13(後輪)の案内手段を成すショックアブソーバ1を、そのストローク方向が車両の上下方向となるよう配置して設け、
該ショックアブソーバ1を成すシリンダ2を、車両前後方向および車幅方向に拘束して車体11に結合し、
ショックアブソーバ1を成すロッド4に橋絡ブラケット33を介してアクスル部材13(後輪)を連結した構成になるから、
上下方向に延在するショックアブソーバ1が、それ単独でアクスル部材13(後輪)を車幅方向に拘束し、従来のようにアクスル部材13から車幅方向内方へ延在する部材を要することなく、アクスル部材13(後輪)を車幅方向に拘束して上下動可能に案内することとなり、
車幅方向内方へ延在する部材の揺動スペースを車体床下に確保する必要がなくて、車体床下が車室内へ張り出すこともないので、車室内空間が犠牲になって十分な乗員空間を確保し難くなるという従来装置の前記した問題を解消することができる。
By the way, according to the independent suspension device according to the present configuration example, the shock absorber 1 that constitutes the guide means of the axle member 13 (rear wheel) is provided so that its stroke direction is the vertical direction of the vehicle,
The cylinder 2 constituting the shock absorber 1 is constrained in the vehicle longitudinal direction and the vehicle width direction and coupled to the vehicle body 11,
Since the axle member 13 (rear wheel) is connected to the rod 4 constituting the shock absorber 1 via the bridging bracket 33,
The shock absorber 1 extending in the vertical direction needs to restrain the axle member 13 (rear wheel) in the vehicle width direction by itself, and requires a member extending inward in the vehicle width direction as in the prior art. Without restricting the axle member 13 (rear wheel) in the vehicle width direction, it will be guided to move up and down.
Since there is no need to secure a swinging space for the members extending inward in the vehicle width direction under the vehicle body floor and the vehicle body floor does not protrude into the vehicle interior, sufficient passenger space is sacrificed at the expense of vehicle interior space. It is possible to solve the above-mentioned problem of the conventional apparatus that it is difficult to ensure the above.

また、アクスル部材13(後輪)を車幅方向に拘束するための、車幅方向内方へ延在する部材が必要でないということは、それだけ部品点数の減少によりコスト上、および重量の点でも有利になることを意味する。   In addition, the fact that a member extending inward in the vehicle width direction for restraining the axle member 13 (rear wheel) in the vehicle width direction is not necessary means that in terms of cost and weight, the number of parts is reduced accordingly. It means to be advantageous.

ところで本実体構成例になる独立懸架装置によれば、アクスル部材13(後輪)の上記案内を司るショックアブソーバ1を、図2に明示するごとく1個のシリンダ2と、これに貫通させてシリンダ2の両端部から突出する1本のロッド4とを有する構成としたから、
ショックアブソーバ1を図3や図4のように2個のシリンダ2a,2bおよび2本のロッド4a,4bを有する構成にする場合よりも強度上有利である。
なお図18〜図20の実体構成例では、シリンダ2両端部から突出する1本のロッド4の両端を共に橋絡ブラケット33を介してアクスル部材13に結合したから、ショックアブソーバ1に対するアクスル部材13の取り付け剛性が高くなるが、この取り付け剛性の要求程度によっては、ロッド4の一端のみにアクスル部材13を結合するようにしてもよいことは言うまでもない。
この場合ショックアブソーバ1は、ロッド4がシリンダ2の一端部のみから突出する一般的なショックアブソーバでよいことは勿論である。
By the way, according to the independent suspension device according to the present real configuration example, the shock absorber 1 that controls the above-mentioned guidance of the axle member 13 (rear wheel) is made to pass through one cylinder 2 and the cylinder as shown in FIG. Since it has a configuration with one rod 4 projecting from both ends of 2,
The shock absorber 1 is advantageous in terms of strength as compared with the case where the shock absorber 1 has two cylinders 2a and 2b and two rods 4a and 4b as shown in FIGS.
18 to 20, since both ends of one rod 4 protruding from both ends of the cylinder 2 are coupled to the axle member 13 via the bridging bracket 33, the axle member 13 with respect to the shock absorber 1 is used. However, it goes without saying that the axle member 13 may be coupled to only one end of the rod 4 depending on the required degree of attachment rigidity.
In this case, the shock absorber 1 may be a general shock absorber in which the rod 4 protrudes from only one end of the cylinder 2.

なお上記した何れの実体構成例においても、アクスル部材13をトー方向に拘束するトレーリングメンバとして板バネ14を用いたから、これが前記したように、アクスル部材13(後輪)のバウンド、リバウンドを緩衝下に行わせるサスペンションスプリングの用もなし、サスペンションスプリングを省略することができて、コスト上および軽量化の点で大いに有利である。   In any of the above-described actual structural examples, the leaf spring 14 is used as a trailing member for restraining the axle member 13 in the toe direction, and as described above, the axle member 13 (rear wheel) bounds and rebounds are buffered. There is no use of a suspension spring to be performed below, and the suspension spring can be omitted, which is very advantageous in terms of cost and weight reduction.

また上記した何れの実体構成例においても、アクスル部材13(後輪)を上下方向に案内する案内手段としてショックアブソーバ1を用いたから、この点でも部品点数の減少を図り得てコスト上および軽量化の点で有利であるだけでなく、アクスル部材13(後輪)用の案内手段を設置するスペースと、ショックアブソーバの設置スペースとを個別に用意する必要がなくて、独立懸架装置の省スペース化と、設計の容易化とを実現することができる。   In any of the above-described examples of the actual configuration, the shock absorber 1 is used as the guide means for guiding the axle member 13 (rear wheel) in the vertical direction. In this respect, the number of parts can be reduced and the cost and weight can be reduced. In addition to this, it is not necessary to separately prepare a space for installing the guide means for the axle member 13 (rear wheel) and a space for installing the shock absorber. And facilitating design.

さりとて、アクスル部材13(後輪)用の案内手段と、ショックアブソーバとを共通化する必要は必ずしもなく、これらを図21に示すように別個のものとして構成することもできる。
図21の実体構成例では、アクスル部材13(後輪)用の案内手段をガイドロッド41およびスライド部材42により構成する。
ガイドロッド41は、前記したショックアブソーバ1と同様、上下方向に延在するよう、ただし、アンチダイブ性向上のために後傾させて配置し、ガイドロッド41の上下両端をそれぞれ車体11に結合して、車両前後方向および車幅方向に拘束する。
なお、ガイドロッド41は上下両端を車体11に結合するのが取り付け強度上有利であるが、要求される取り付け強度によってはガイドロッド41の上下一端のみを車体11に結合してもよい。
As a matter of course, it is not always necessary to share the guide means for the axle member 13 (rear wheel) and the shock absorber, and these may be configured separately as shown in FIG.
21, the guide means for the axle member 13 (rear wheel) is constituted by a guide rod 41 and a slide member 42.
As with the shock absorber 1 described above, the guide rod 41 extends in the up-down direction, but is tilted backward to improve the anti-dive property, and the upper and lower ends of the guide rod 41 are coupled to the vehicle body 11 respectively. The vehicle is restrained in the vehicle longitudinal direction and the vehicle width direction.
Although it is advantageous in terms of mounting strength that the upper and lower ends of the guide rod 41 are coupled to the vehicle body 11, only the upper and lower ends of the guide rod 41 may be coupled to the vehicle body 11 depending on the required mounting strength.

スライド部材42はガイドロッド41上に摺動自在に嵌合して、ガイドロッド41に対しその軸線方向に相対変位可能とし、このスライド部材42にアクスル部材13を結合する。
アクスル部材13はガイドロッド41の軸線周りでトー方向に回動可能であり、アクスル部材13を該トー方向に拘束する必要がある。
これがため本実体構成例では、図10につき前述したと同様、アクスル部材13をトー方向に拘束するトレーリングメンバとしてリンク25を設け、これをアクスル部材13から車両前方に延在させる。
The slide member 42 is slidably fitted on the guide rod 41 so as to be capable of relative displacement in the axial direction with respect to the guide rod 41, and the axle member 13 is coupled to the slide member 42.
The axle member 13 can rotate in the toe direction around the axis of the guide rod 41, and the axle member 13 needs to be restrained in the toe direction.
For this reason, in this actual configuration example, the link 25 is provided as a trailing member that restrains the axle member 13 in the toe direction, and extends from the axle member 13 to the front of the vehicle, as described above with reference to FIG.

車両前後方向に延在されるかかる縦置きリンク25の後端を1個のシャックル30を介してアクスル部材13に連結し、リンク25の前端を、車幅方向に横置きしたトーションバー29の外端に結合して、リンク25によりアクスル部材13をトー方向に拘束するようになす。
該横置きトーションバー29の内端はアーム43を介してショックアブソーバ44のロッド44aに連結し、横置きトーションバー29の両端間中程を車体11に回転自在に支持する。
なおショックアブソーバ44は、ロッド44aがシリンダ44bの一端部のみから抜き差し可能に突出する一般的なショックアブソーバとし、シリンダ44bを車体11に連結する。
The rear end of the longitudinal link 25 extending in the vehicle front-rear direction is connected to the axle member 13 via a single shackle 30, and the front end of the link 25 is attached to the outside of the torsion bar 29 placed horizontally in the vehicle width direction. The axle member 13 is constrained in the toe direction by the link 25 by being coupled to the end.
The inner end of the horizontally mounted torsion bar 29 is connected to a rod 44a of a shock absorber 44 via an arm 43, and the middle between both ends of the horizontally mounted torsion bar 29 is rotatably supported by the vehicle body 11.
The shock absorber 44 is a general shock absorber in which the rod 44a protrudes from only one end of the cylinder 44b so that it can be inserted and removed, and connects the cylinder 44b to the vehicle body 11.

本実体構成例になる独立懸架装置の作用を次に説明する。
アクスル部材13(後輪)は、バウンド、リバウンド時、ガイドロッド41によりスライド部材42を介し案内されて、図21にα,βで示すガイドロッド41の軸線方向に上下動する。
この間、リンク25はアクスル部材13(後輪)のトー方向位置を拘束し、無用な後輪のトー角の変化を防止する。
リンク25は更に、アクスル部材13(後輪)のバウンド、リバウンドに伴って横置きトーションバー29の軸線周りに回動し、該横置きトーションバー29の捻りおよびアーム43を介してショックアブソーバ44をストロークさせる。
Next, the operation of the independent suspension apparatus according to this example of the actual configuration will be described.
The axle member 13 (rear wheel) is guided through the slide member 42 by the guide rod 41 during bounding and rebounding, and moves up and down in the axial direction of the guide rod 41 indicated by α and β in FIG.
During this time, the link 25 restrains the position of the axle member 13 (rear wheel) in the toe direction to prevent useless changes in the toe angle of the rear wheel.
The link 25 further rotates around the axis of the lateral torsion bar 29 as the axle member 13 (rear wheel) bounces and rebounds, and the shock absorber 44 is moved via the twist of the lateral torsion bar 29 and the arm 43. Stroke.

この間ショックアブソーバ44は、アクスル部材13(後輪)のバウンド、リバウンド方向のストローク振動を減衰させ、一方で横置きトーションバー29は、上記捻れにより生起されるバネ作用でサスペンションスプリングの用をなし、アクスル部材13(後輪)のバウンド、リバウンドに対して所定の緩衝機能をも果たす。   During this time, the shock absorber 44 attenuates stroke vibration in the bound and rebound directions of the axle member 13 (rear wheel), while the lateral torsion bar 29 is used as a suspension spring by the spring action caused by the torsion, It also performs a predetermined buffering function against the bound and rebound of the axle member 13 (rear wheel).

アクスル部材13(後輪)は、そのバウンド、リバウンド時、図11につき前述したごとく車両前後方向の変位を伴って上下動し、リンク25に対して干渉しようとする。
しかしこの時シャックル30が、図11につき前述したシャックル17,18と同様に機能(回動)して、アクスル部材13(後輪)のバウンド、リバウンド時における前後方向変位を吸収し得るため、アクスル部材13(後輪)の前後方向変位を伴ったバウンド、リバウンドがリンク25によって妨げられることはない。
The axle member 13 (rear wheel) moves up and down with displacement in the longitudinal direction of the vehicle as described above with reference to FIG.
However, at this time, the shackle 30 functions (rotates) in the same manner as the shackles 17 and 18 described above with reference to FIG. 11, and can absorb the displacement in the front-rear direction when the axle member 13 (rear wheel) bounces and rebounds. The bounce and rebound accompanied by the longitudinal displacement of the member 13 (rear wheel) is not hindered by the link 25.

ところで本実体構成例になる独立懸架装置によれば、アクスル部材13(後輪)の案内手段を成すガイドロッド41およびスライド部材42を、スライド部材42のストローク方向が車両の上下方向となるよう配置して設け、
ガイドロッド41を、車両前後方向および車幅方向に拘束して車体11に連結し、
スライド部材42にアクスル部材13を連結した構成になるから、
上下方向に延在する案内手段(ガイドロッド41およびスライド部材42)が、それ単独でアクスル部材13(後輪)を車幅方向に拘束し、従来のようにアクスル部材13から車幅方向内方へ延在する部材を要することなく、アクスル部材13(後輪)を車幅方向に拘束して上下動可能に案内することとなり、
車幅方向内方へ延在する部材の揺動スペースを車体床下に確保する必要がなくて、車体床下が車室内へ張り出すこともないので、車室内空間が犠牲になって十分な乗員空間を確保し難くなるという従来装置の前記した問題を解消することができる。
By the way, according to the independent suspension device according to the present configuration example, the guide rod 41 and the slide member 42 that constitute the guide means of the axle member 13 (rear wheel) are arranged such that the stroke direction of the slide member 42 is the vertical direction of the vehicle. Provided,
The guide rod 41 is constrained in the vehicle front-rear direction and the vehicle width direction to be connected to the vehicle body 11,
Since the axle member 13 is connected to the slide member 42,
The guide means (the guide rod 41 and the slide member 42) extending in the vertical direction independently restrains the axle member 13 (rear wheel) in the vehicle width direction, and inward in the vehicle width direction from the axle member 13 as in the past. Without requiring a member extending to the front, the axle member 13 (rear wheel) is restrained in the vehicle width direction and guided so as to move up and down.
Since there is no need to secure a swinging space for the members extending inward in the vehicle width direction under the vehicle body floor and the vehicle body floor does not protrude into the vehicle interior, sufficient passenger space is sacrificed at the expense of vehicle interior space. It is possible to solve the above-mentioned problem of the conventional apparatus that it is difficult to ensure the above.

なお、本実体構成例のようにアクスル部材13(後輪)の案内手段をガイドロッド41およびスライド部材42により構成する場合、この案内手段を前記した実体構成例のようにショックアブソーバ1により構成する場合に較べ、案内手段の直径が小さくなってこれをアクスル部材13の近くの限られたスペースにも容易に配置することができると共に、案内手段の強度を比較的自由に高めることができて設計の自由度が高い。   When the guide means for the axle member 13 (rear wheel) is constituted by the guide rod 41 and the slide member 42 as in this example of the actual configuration, this guide means is configured by the shock absorber 1 as in the aforementioned actual configuration example. Compared to the case, the guide means has a smaller diameter and can be easily arranged in a limited space near the axle member 13, and the strength of the guide means can be increased relatively freely. High degree of freedom.

また、アクスル部材13(後輪)の上下動をショックアブソーバ44に伝達する伝動系に横置きトーションバー29を用い、これがサスペンションスプリングとしても機能するようにした構成故に、サスペンションスプリングを省略し得て部品点数の減少とその設置スペースの節約とを実現することができる。
なお、リンク25を前記した板バネ14に置換してこれにサスペンションスプリングの機能を持たせてもサスペンションスプリングを省略し得ることは言うまでもない。
この場合、横置きトーションバー29は捻りバネ作用を持たないロッドでよいこと勿論である。
In addition, because the horizontal torsion bar 29 is used in the transmission system that transmits the vertical movement of the axle member 13 (rear wheel) to the shock absorber 44 and this also functions as a suspension spring, the suspension spring can be omitted. It is possible to reduce the number of parts and save the installation space.
It goes without saying that the suspension spring can be omitted by replacing the link 25 with the plate spring 14 described above to provide the function of the suspension spring.
In this case, it goes without saying that the lateral torsion bar 29 may be a rod having no torsion spring action.

また本実体構成例において用いるショックアブソーバ44は、図21に示したように液体を作動媒体とする型式のものに限られず、電気的な負荷をかけて振動を減衰するような電気式のショックアブソーバでもよいし、その他どのような型式のショックアブソーバも採用可能である。   Further, the shock absorber 44 used in this actual configuration example is not limited to a type using a liquid as a working medium as shown in FIG. 21, but an electric shock absorber that attenuates vibration by applying an electric load. However, any other type of shock absorber can be used.

なお、上記いずれの実体構成例においても、前輪駆動車の後輪用に好適な独立懸架装置として構成したが、同様な考え方により前輪用の独立懸架装置として構成し得ること勿論である。   In any of the above-described actual configuration examples, the independent suspension device suitable for the rear wheels of the front wheel drive vehicle is configured. However, it is needless to say that the same suspension can be configured as an independent suspension device for the front wheels.
