Description

本発明は、車両用フレーム構造に関するものである。   The present invention relates to a vehicle frame structure.

従来よりトラック等の車両に関するフレーム構造にあっては、鉄板をプレス成形することにより得られた車両前後方向に延びる左右一対のサイドメンバを主構成とし、これら各サイドメンバに対し車幅方向に延びるクロスメンバを適宜数組み付けて梯子型のフレーム構造を成すように構成されているのが一般的である。   Conventionally, in a frame structure relating to a vehicle such as a truck, a pair of left and right side members extending in the vehicle front-rear direction obtained by press forming an iron plate is a main component, and extends in the vehicle width direction with respect to each side member. In general, a ladder-type frame structure is formed by assembling a suitable number of cross members.

即ち、図３に示す如く、チャンネル形のサイドメンバ１，１における上部のフランジ２，２同士及び下部のフランジ３，３同士を鉄板プレス品のクロスメンバ４，５により夫々連結し、その連結部分に対しガセット６，７で補強を施すようにしたものがある（例えば、特許文献１参照）。
特開平６−１８３３６９号公報（図４） That is, as shown in FIG. 3, the upper flanges 2 and 2 and the lower flanges 3 and 3 of the channel-shaped side members 1 and 1 are connected to each other by the cross members 4 and 5 of the iron plate press product. On the other hand, there is one in which reinforcement is performed by gussets 6 and 7 (see, for example, Patent Document 1).
JP-A-6-183369 (FIG. 4)

そして、図３に示す例では、各サイドメンバ１，１が、サスペンションとしてリーフスプリングを装備するようにしたものとなっており、該リーフスプリングの端部を枢着するためのスプリングブラケット８，８が、各サイドメンバ１，１のフランジ３下面及びウェブ９外側面に対してリベットやボルトにより締結されるようになっている。   In the example shown in FIG. 3, each of the side members 1 and 1 is provided with a leaf spring as a suspension, and spring brackets 8 and 8 for pivotally attaching the end of the leaf spring. However, the side members 1 and 1 are fastened to the lower surface of the flange 3 and the outer surface of the web 9 by rivets or bolts.

尚、リーフスプリングの端部は、上向きに巻かれてアイを形成するようになっており、このアイに通したピンをスプリングブラケット８，８で軸支できるようになっていれば良いので、該スプリングブラケット８，８は、ピンの両端部を軸支して水平保持できるよう逆Ｕ字形断面の二股部位を持つものとなっている。   The end of the leaf spring is wound upward to form an eye, and it is sufficient that the pin passing through the eye can be pivotally supported by the spring brackets 8 and 8. The spring brackets 8, 8 have bifurcated portions with an inverted U-shaped cross section so that both ends of the pin can be pivotally supported and held horizontally.

しかしながら、斯かる従来構造においては、左右のサイドメンバ１，１に対し個別にスプリングブラケット８，８を取り付けるようにしていたため、各サイドメンバ１，１に対するスプリングブラケット８，８の取り付け位置が左右でばらつき易く、該各スプリングブラケット８，８を精度良く取り付けることが難しいという問題があった。   However, in such a conventional structure, since the spring brackets 8, 8 are individually attached to the left and right side members 1, 1, the mounting positions of the spring brackets 8, 8 to the side members 1, 1 are left and right. There was a problem that it was easy to vary and it was difficult to attach the spring brackets 8 and 8 with high accuracy.

本発明は上述の実情に鑑みてなしたもので、左右のサイドメンバに対しスプリングブラケットを精度良く取り付け得るようにした車両用フレーム構造を提供することを目的としている。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle frame structure in which spring brackets can be attached to left and right side members with high accuracy.

本発明は、車両前後方向に延びる左右のサイドメンバ間にクロスメンバを架設して成る車両用フレーム構造であって、クロスメンバの両端部上側に各サイドメンバ下端を嵌合可能な溝部が凹設され且つ該各溝部の下側にリーフスプリングの端部を枢着し得るスプリングブラケットが一体成形されていることを特徴とするものである。   The present invention relates to a vehicle frame structure in which a cross member is installed between left and right side members extending in the vehicle front-rear direction, and a groove portion into which a lower end of each side member can be fitted is provided on both upper sides of the cross member. In addition, a spring bracket capable of pivotally attaching an end portion of the leaf spring is integrally formed below each groove portion.

而して、このような車両用フレーム構造を採用した場合に、クロスメンバの両端部上側の溝部に各サイドメンバ下端を嵌合させて各サイドメンバとクロスメンバとの組み付けを行うと、該クロスメンバに一体成形されている各スプリングブラケットが同時に取り付けられることになり、従来の如き各スプリングブラケットを個別に取り付けることで生じていた左右のバラツキが生じなくなる。   Thus, when such a vehicle frame structure is employed, when the side member lower end is fitted in the groove on the upper side of both ends of the cross member and the side member and the cross member are assembled, the cross member The spring brackets integrally formed with the member are attached at the same time, and the left and right variations that are caused by attaching the spring brackets individually as in the prior art do not occur.

しかも、クロスメンバの両端部上側の溝部に各サイドメンバ下端を嵌合させることで該各サイドメンバ間の幅寸法が決まるので、クロスメンバの組み付け時に各サイドメンバ間の幅寸法を精度良く確保しながら作業を進めることが可能となる。   In addition, since the width dimension between the side members is determined by fitting the lower end of each side member into the groove on the upper side of both ends of the cross member, the width dimension between the side members can be accurately secured when the cross member is assembled. It is possible to proceed while working.

また、従来において別部品であったクロスメンバと左右のスプリングブラケットとが一体成形されたものとなって一部品として扱えるようになり、部品点数の大幅な削減が図られることになる。   In addition, the cross member and the left and right spring brackets, which are separate parts in the past, are integrally formed and can be handled as one part, and the number of parts can be greatly reduced.

更に、本発明においては、クロスメンバがアルミニウム製であることが好ましく、このようにすれば、従来の如き鉄板プレス品のクロスメンバを採用していた場合と比較してフレーム重量の大幅な軽量化が図られる。   Furthermore, in the present invention, it is preferable that the cross member is made of aluminum, and in this way, the weight of the frame is significantly reduced as compared with the case where a cross member made of an iron plate press is used. Is planned.

（Ｉ）各サイドメンバへのクロスメンバの組み付けを行うだけで各スプリングブラケットを同時に取り付けることができるので、従来の如き各スプリングブラケットを個別に取り付けることで生じていた左右のバラツキをなくすことができ、各スプリングブラケットの取り付け精度を従来より大幅に向上することができる。   (I) Since the spring brackets can be attached at the same time by simply assembling the cross members to the side members, the left and right variations caused by attaching the individual spring brackets individually can be eliminated. The mounting accuracy of each spring bracket can be greatly improved as compared with the prior art.

（ＩＩ）クロスメンバの両端部上側の溝部に各サイドメンバ下端を嵌合させることで該各サイドメンバ間の幅寸法を決めることができるので、クロスメンバの組み付け時に各サイドメンバ間の幅寸法を精度良く確保しながら作業を進めることができ、クロスメンバの組み付け後における各サイドメンバ間の幅寸法の精度を従来より大幅に向上することができる。   (II) Since the width dimension between the side members can be determined by fitting the lower end of each side member into the groove on the upper side of both ends of the cross member, the width dimension between the side members can be determined when the cross member is assembled. The work can be carried out while ensuring high accuracy, and the accuracy of the width dimension between the side members after the assembly of the cross member can be greatly improved as compared with the prior art.

（ＩＩＩ）クロスメンバに左右のスプリングブラケットを一体成形したことにより部品点数を大幅に削減できるので、組み付け工程を簡素化して作業労力を著しく軽減することができる。   (III) Since the left and right spring brackets are integrally formed on the cross member, the number of parts can be greatly reduced, so that the assembling process can be simplified and work labor can be remarkably reduced.

（ＩＶ）クロスメンバをアルミニウム製とした構成を採用すれば、従来の如き鉄板プレス品のクロスメンバを採用していた場合と比較してフレーム重量の大幅な軽量化を図ることができる。   (IV) By adopting a configuration in which the cross member is made of aluminum, the weight of the frame can be significantly reduced as compared with the case where a cross member made of an iron plate press is used.

以下本発明の実施の形態を図面を参照しつつ説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１及び図２は本発明を実施する形態の一例を示すもので、図３と同一の符号を付した部分は同一物を表わしている。   1 and 2 show an example of an embodiment for carrying out the present invention, and portions denoted by the same reference numerals as those in FIG. 3 represent the same items.

図示する如く、本形態例においては、左右のサイドメンバ１，１間に架設されるクロスメンバ１０が、以下に詳述する如きアルミニウム製の一体鋳造物として構成されている。   As shown in the figure, in this embodiment, the cross member 10 installed between the left and right side members 1 and 1 is formed as an integral casting made of aluminum as described in detail below.

即ち、このクロスメンバ１０の両端部上側には、各サイドメンバ１，１下端を嵌合可能な溝部１１，１１が凹設されており、しかも、前記各溝部１１，１１の下側には、リーフスプリングの端部を枢着し得るスプリングブラケット１２，１２が一体成形されている。   That is, on the upper side of both end portions of the cross member 10, groove portions 11 and 11 into which the lower ends of the side members 1 and 1 can be fitted are recessed, and below the groove portions 11 and 11, Spring brackets 12, 12 that can pivotally attach the end of the leaf spring are integrally formed.

尚、このスプリングブラケット１２，１２は、リーフスプリングの端部にあるアイに通したピンの両端部を軸支して水平保持できるよう逆Ｕ字形断面の二股部位を持つものとなっており、しかも、必要な箇所をリブ立てにより補強した形状を採用してある。   Each of the spring brackets 12 and 12 has a bifurcated portion having an inverted U-shaped cross section so that both ends of the pin passing through the eye at the end of the leaf spring can be pivotally supported and held horizontally. The shape where the necessary part is reinforced by the rib stand is adopted.

而して、このような車両用フレーム構造を採用した場合、クロスメンバ１０の両端部上側の溝部１１，１１に各サイドメンバ１，１下端を嵌合させて各サイドメンバ１，１とクロスメンバ１０との組み付けを行うと、該クロスメンバ１０に一体成形されている各スプリングブラケット１２，１２が同時に取り付けられることになり、従来の如き各スプリングブラケット１２，１２を個別に取り付けることで生じていた左右のバラツキが生じなくなる。   Thus, when such a vehicle frame structure is adopted, the lower ends of the side members 1 and 1 are fitted into the groove portions 11 and 11 at the upper ends of the both ends of the cross member 10, and the side members 1 and 1 and the cross member are fitted. 10, the spring brackets 12, 12 integrally formed with the cross member 10 are attached at the same time, which is caused by attaching the spring brackets 12, 12 as in the prior art. There will be no left-right variation.

しかも、クロスメンバ１０の両端部上側の溝部１１，１１に各サイドメンバ１，１下端を嵌合させることで該各サイドメンバ１，１間の幅寸法が決まるので、クロスメンバ１０の組み付け時に各サイドメンバ１，１間の幅寸法を精度良く確保しながら作業を進めることが可能となる。   Moreover, since the width dimension between the side members 1 and 1 is determined by fitting the lower ends of the side members 1 and 1 into the grooves 11 and 11 at the upper ends of both ends of the cross member 10, It is possible to proceed with work while ensuring the width dimension between the side members 1 and 1 with high accuracy.

また、従来において別部品であったクロスメンバ１０と左右のスプリングブラケット１２，１２とが一体成形されたものとなって一部品として扱えるようになり、部品点数の大幅な削減が図られることになる。   In addition, the cross member 10 and the left and right spring brackets 12 and 12 which are separate parts in the past are integrally molded and can be handled as one part, so that the number of parts can be greatly reduced. .

従って、上記形態例によれば、各サイドメンバ１，１へのクロスメンバ１０の組み付けを行うだけで各スプリングブラケット１２，１２を同時に取り付けることができるので、従来の如き各スプリングブラケット１２，１２を個別に取り付けることで生じていた左右のバラツキをなくすことができ、各スプリングブラケット１２，１２の取り付け精度を従来より大幅に向上することができる。   Therefore, according to the above embodiment, the spring brackets 12 and 12 can be attached at the same time only by assembling the cross members 10 to the side members 1 and 1, respectively. It is possible to eliminate the left and right variations caused by the individual mounting, and it is possible to greatly improve the mounting accuracy of the spring brackets 12 and 12 as compared with the prior art.

また、クロスメンバ１０の両端部上側の溝部１１，１１に各サイドメンバ１，１下端を嵌合させることで該各サイドメンバ１，１間の幅寸法を決めることができるので、クロスメンバ１０の組み付け時に各サイドメンバ１，１間の幅寸法を精度良く確保しながら作業を進めることができ、クロスメンバ１０の組み付け後における各サイドメンバ１，１間の幅寸法の精度を従来より大幅に向上することができる。   Further, the width dimension between the side members 1 and 1 can be determined by fitting the lower ends of the side members 1 and 1 into the groove portions 11 and 11 on both upper ends of the cross member 10. Work can be carried out while ensuring the width dimension between the side members 1 and 1 with high accuracy at the time of assembly, and the accuracy of the width dimension between the side members 1 and 1 after the cross member 10 is assembled is greatly improved. can do.

更に、クロスメンバ１０に左右のスプリングブラケット１２，１２を一体成形したことにより部品点数を大幅に削減できるので、組み付け工程を簡素化して作業労力を著しく軽減することができる。   Furthermore, since the left and right spring brackets 12 and 12 are integrally formed with the cross member 10, the number of parts can be greatly reduced, so that the assembling process can be simplified and work labor can be remarkably reduced.

また、特に本形態例においては、クロスメンバ１０をアルミニウム製としているので、従来の如き鉄板プレス品のクロスメンバ１０を採用していた場合と比較してフレーム重量の大幅な軽量化を図ることができる。   In particular, in the present embodiment, since the cross member 10 is made of aluminum, the weight of the frame can be significantly reduced as compared with the case where the cross member 10 of a conventional steel plate press product is adopted. it can.

尚、本発明の車両用フレーム構造は、上述の形態例にのみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   It should be noted that the vehicle frame structure of the present invention is not limited to the above-described embodiments, and it is needless to say that various changes can be made without departing from the gist of the present invention.
