本考案は、車両のリヤサスペンション取付部構造に関するものである。 The present invention relates to a vehicle rear suspension mounting structure.
【０００２】[0002]
車両のリヤサスペンションは、図３に示すように車体のクロスメンバに上下揺 動可能に軸着したサスペンションアームとホイールエプロンａの一部に筒状に凸 設したサスペンションタワーｂとの間に、ショックアブソーバｃ及び又はサスペ ンションスプリングｄを介装し、サスペンション反力をショックアブソーバｃや サスペンションスプリングｄを介してサスペンションタワーｂと該サスペンショ ンタワーを形成したホイールエプロンａと該ホイールエプロンに固着したサイド フレームｅ，リヤピラーインナｆ等で分散して吸収するよう構成しているのが一 般的である（例えば実開昭６０−６８８７５号公報参照）。 As shown in FIG. 3, the rear suspension of a vehicle has a shock generated between a suspension arm pivotally mounted on a cross member of a vehicle body so as to be able to swing up and down and a suspension tower b projecting in a cylindrical shape on a part of a wheel apron a. A side frame e fixed to the wheel apron a and a wheel apron that form a suspension tower b and the suspension tower via a shock absorber c and a suspension spring d via a shock absorber c and / or a suspension spring d. Generally, the rear pillar inner f and the like are configured to disperse and absorb the dispersion (see, for example, Japanese Utility Model Laid-Open No. 60-68875).
【０００３】[0003]
上記のようなリヤサスペンション取付構造のものにおいては、凸設したサスペ ンションタワーｂがトランクルームの容積を狭めるという課題を有しており、そ のような課題を解決するためにサスペンションタワーを廃止し、サスペンション アームとサイドフレームｅの下面との間にショックアブソーバｃ及び又はサスペ ンションスプリングｄを介装するという手段が従来より採られている。ところが このような構成を採用するとショックアブソーバｃやサスペンションスプリング ｄの許容伸縮ストロークはサイドフレームｅのフロア面より下方への突出高さに よって制限されざるを得ず、該許容伸縮ストロークをあまり大きく採ることがで きないという課題が生じる。 In the case of the above rear suspension mounting structure, the convex suspension tower b has a problem of narrowing the volume of the trunk room. To solve such a problem, the suspension tower is abolished, Conventionally, a means of interposing a shock absorber c and / or a suspension spring d between the suspension arm and the lower surface of the side frame e has been adopted. However, if such a configuration is adopted, the allowable expansion / contraction stroke of the shock absorber c and the suspension spring d must be limited by the protruding height of the side frame e below the floor surface, and the allowable expansion / contraction stroke is too large. The problem arises that things cannot be done.
【０００４】 サイドフレームの断面高さを部分的に低くすれば上記ショックアブソーバやサ スペンションスプリングの許容伸縮ストロークを大きくすることはできるが、サ イドフレームの断面高さを低くするとフレーム強度が低下するという問題が生じ る。即ち、サイドフレームはフロアの側縁下部に沿って固着され前後方向の閉断 面を形成するものであり、その縦壁がフレーム強度に支配的に機能するので、そ の縦壁高さを部分的に低くするとリヤサスペンション取付部付近の強度剛性が低 下し、振動騒音対策及び操安性等の面で好ましくない。Although the allowable expansion / contraction stroke of the shock absorber or the suspension spring can be increased by partially lowering the sectional height of the side frame, lowering the sectional height of the side frame lowers the frame strength. The problem arises. That is, the side frame is fixed along the lower part of the side edge of the floor to form a closed surface in the front-rear direction. If it is made too low, the strength and rigidity near the rear suspension mounting part will decrease, which is not desirable in terms of measures against vibration and noise and safety.
【０００５】 本考案は上記のような従来の課題に対処することを目的とするものである。The present invention aims to address the above-mentioned conventional problems.
【０００６】[0006]
本考案は、フロアの側縁下面に接合固着され前後方向の閉断面を形成するサイ ドフレームの下面にリヤサスペンションのストラット上端部を嵌挿取付けるため の取付穴を設け、該サイドフレームの該取付穴を設けた位置の内側縦壁面に、車 体前後方向に対しほぼ４５°の角度をもって内側に突出する前後の傾斜縦壁面を 有する内側膨出部を形成し、該サイドフレームの内側膨出部形成部内に下開きの ほぼ箱形状のサスブラケットを上記サイドフレーム下面の取付穴を囲むように嵌 装固着し、フロア下面に接合固着されて車幅方向の閉断面を形成するクロスメン バの側端部を、該クロスメンバの前後の縦壁面側端に形成した傾斜接合面をサイ ドフレームの前後の傾斜縦壁面に接合してサスブラケットの内側縦面に形成した 傾斜縦面と重ねて固着すると共にクロスメンバの下面をサイドフレームの下面に 接合固着して、サイドフレームとサスブラケットとに結合し、該サスブラケット の上面にリヤサスペンションのストラット上端部を取付けるようにしたことを特 徴とするものである。 The present invention provides a mounting hole for fitting and mounting the upper end of the strut of the rear suspension on the lower surface of the side frame which is fixedly joined to the lower surface of the side edge of the floor to form a closed cross section in the front-rear direction. An inner bulge portion is formed on the inner vertical wall surface at the position where the hole is formed, and has front and rear inclined vertical wall surfaces that project inward at an angle of approximately 45 ° with respect to the vehicle longitudinal direction. A side-end of the cross member that forms a closed cross section in the vehicle width direction by fitting and fixing a downward-opening, substantially box-shaped suspension bracket in the forming part so as to surround the mounting hole on the lower surface of the side frame, and bonding and fixing to the lower surface of the floor. Of the cross member, the inclined joint surfaces formed on the front and rear vertical wall side ends of the cross member are joined to the front and rear inclined vertical wall surfaces of the side frame, and overlap with the inclined vertical surfaces formed on the inner vertical surface of the suspension bracket. In addition to fixing, the lower surface of the cross member is joined and fixed to the lower surface of the side frame so as to be connected to the side frame and the suspension bracket, and the upper end of the strut of the rear suspension is attached to the upper surface of the suspension bracket. To do.
【０００７】[0007]
上記のように、サイドフレーム内に嵌装固着したサスブラケットの上面でリヤ サスペンションのサスペンション荷重受面を構成したことにより、ショックアブ ソーバとサスペンションスプリングとからなるストラットの許容伸縮ストローク を従来に比し大きく採ることができ、サイドフレームはフレーム強度に最も大き な影響をもつ縦壁の高さが低くならず且つサイドフレーム下面の取付穴周縁部は サスブラケットの内外及び前後の縦面で囲まれ該サスブラケットが取付穴周縁部 付近の補強部材としての機能を果たしていること、及びサイドフレームの内側縦 壁面とクロスメンバの縦壁面側端部との結合が前後方向に対しほぼ４５°の角度 をもつ傾斜面同士の接合固着としたことで当該接合固着部に剥離荷重が入らず荷 重入力に対し非常に強固な結合となりサスペンション荷重がサイドフレームとク ロスメンバとに的確に分散される構造であることによって、リヤサスペンション 取付部付近の強度剛性は大幅に向上し、振動騒音の低減及び操安性の向上をはか り得る。 As described above, by configuring the suspension load receiving surface of the rear suspension by the upper surface of the suspension bracket that is fitted and fixed in the side frame, the allowable expansion and contraction stroke of the strut composed of the shock absorber and the suspension spring can be compared with the conventional model. The side frame has the largest influence on the frame strength, and the height of the vertical wall does not decrease, and the peripheral edge of the mounting hole on the lower surface of the side frame is surrounded by the inside and outside of the suspension bracket and the front and rear vertical surfaces. The suspension bracket functions as a reinforcing member near the periphery of the mounting hole, and the connection between the inner vertical wall surface of the side frame and the vertical wall surface end of the cross member forms an angle of approximately 45 ° with respect to the front-rear direction. Since the slanted surfaces are joined and fixed together, the peeling load does not enter the jointed and fixed part and is not affected by the load input. The structure is such that the suspension load is accurately distributed between the side frame and the cross member, and the strength and rigidity near the rear suspension mounting part are significantly improved, reducing vibration noise and improving maneuverability. Can be measured.
