Abstract

<P>PROBLEM TO BE SOLVED: To provide a chassis frame structure capable of reducing weight and rationalizing assembling process. <P>SOLUTION: A side rail main body 15 having a rectangular closed cross-section and extending in a vehicular fore-and-aft direction, and a flange 16 projecting downward from a lateral side portion of the side rail main body 15 are integrally formed by extruding aluminum alloy. Side rail lateral cross section is set to have a shape partially closed and large in height dimensions. Therefore, parts count is reduced while ensuring stiffness. A front bolt hole 17 and a rear bolt hole 18 penetrating in a vehicular width direction are bored on the flange 16, and suspension elements are journalled in the bolt holes 17, 18. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明はシャシフレーム構造に関するものである。   The present invention relates to a chassis frame structure.

図４乃至図６は従来のシャシフレーム構造の一例であり、車両前後方向に延びる溝形材よりなるサイドレール１と、該サイドレール１に設けたフロントブラケット２、及びリヤブラケット３と、サイドレール１及びブラケット２，３の双方向に固着されて継手部分を補強するガセットプレート４，５とを備え、前記ブラケット２，３にリーフスプリング６を装着している。   4 to 6 show an example of a conventional chassis frame structure, which includes a side rail 1 made of a groove-shaped member extending in the vehicle longitudinal direction, a front bracket 2 and a rear bracket 3 provided on the side rail 1, and a side rail. 1 and brackets 2 and 3 are fixed in both directions, and gusset plates 4 and 5 are provided to reinforce the joint portion. A leaf spring 6 is mounted on the brackets 2 and 3.

リーフスプリング６の前後端部にはアイ７，８が形成してあり、前方のアイ７をボルト９によってフロントブラケット２のボルト孔１０に枢支し、後方のアイ８をボルト１１によってシャックル１２の一端部に枢支し、該シャックル１２の他端部をリヤブラケット３のボルト孔１３にボルト１４によって枢支し、リーフスプリング６の撓みに起因したアイ７，８の間隔の拡縮を、シャックル１２の変位により許容するようになっている。   Eyes 7 and 8 are formed at the front and rear ends of the leaf spring 6, the front eye 7 is pivotally supported by the bolt 9 in the bolt hole 10 of the front bracket 2, and the rear eye 8 is secured by the bolt 11 to the shackle 12. The shackle 12 is pivotally supported at one end, and the other end of the shackle 12 is pivotally supported by a bolt 14 in the bolt hole 13 of the rear bracket 3 to increase or decrease the distance between the eyes 7 and 8 due to the bending of the leaf spring 6. It is allowed by the displacement of.

また、シャシフレームの素材にアルミニウム合金を用いて、車体の軽量化を図ることが提案されている（例えば、特許文献１参照）。
特開平１０−３１４８６９号公報 Further, it has been proposed to reduce the weight of the vehicle body by using an aluminum alloy as a material for the chassis frame (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-314869

しかしながら、特許文献１には、スプリングなどのサスペンション装置の要素をシャシフレームに装着する構造についての提示はなく、図４乃至図６に示すシャシフレーム構造の素材にアルミニウム合金を用いたとしても、組付工程の合理化は達成されない。   However, Patent Document 1 does not provide a structure for mounting an element of a suspension device such as a spring on a chassis frame. Even if an aluminum alloy is used for the material of the chassis frame structure shown in FIGS. The rationalization of the attachment process is not achieved.

本発明は上述した実情に鑑みてなしたもので、軽量化と組付工程の合理化を達成可能なシャシ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-described circumstances, and an object thereof is to provide a chassis frame structure capable of achieving weight reduction and rationalization of an assembly process.

上記目的を達成するため、本発明は、中空状のサイドレール本体と該サイドレール本体から突出するフランジをアルミニウム合金により一体的に形成し、サスペンション装着用のボルト孔を前記フランジに穿設している。   In order to achieve the above object, according to the present invention, a hollow side rail body and a flange protruding from the side rail body are integrally formed of an aluminum alloy, and bolt holes for mounting a suspension are formed in the flange. Yes.

本発明においては、サスペンションの装着部分となるフランジを中空状のサイドレール本体に一体的に形成し、サイドレール横断面を部分的に閉じた形とする。   In the present invention, a flange serving as a mounting portion of the suspension is formed integrally with the hollow side rail body, and the side rail cross section is partially closed.

本発明では、中空状のサイドレール本体とサスペンションを装着するフランジをアルミニウム合金により一体的に形成して、サイドレール横断面を部分的に閉じた形に設定したので、剛性と組付精度を確保しつつシャシフレームの軽量化を達成することができ、また、サスペンション装着用ブラケットを省いて部品点数の削減を図るので、組付工程が簡略化され、生産性が向上し且つコストが低減する。   In the present invention, the flange for mounting the hollow side rail body and suspension is integrally formed of aluminum alloy, and the side rail cross section is set to be partially closed, ensuring rigidity and assembly accuracy. However, the weight of the chassis frame can be reduced, and the number of parts can be reduced by omitting the suspension mounting bracket, so that the assembly process is simplified, the productivity is improved, and the cost is reduced.

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乃至図３は本発明のシャシフレーム構造の実施の形態の一例を示すもので、矩形状の閉断面を呈して車両前後方向に延びるサイドレール本体１５と、当該サイドレール本体１５の左右側部から下向きに突出するフランジ１６とを、アルミニウム合金の押出加工によって一体的に形成し、サイドレール横断面を、部分的に閉じ且つ高さ寸法が大きい形に設定する。   1 to 3 show an example of an embodiment of the chassis frame structure of the present invention. The side rail body 15 has a rectangular closed cross section and extends in the vehicle front-rear direction, and the left and right sides of the side rail body 15. The flange 16 protruding downward from the part is integrally formed by extrusion of an aluminum alloy, and the side rail cross section is partially closed and set to have a large height dimension.

更に、車両幅方向に貫通する前部ボルト孔１７並びに後部ボルト孔１８をフランジ１６に穿設したうえ、リーフスプリング６の前方のアイ７をボルト９によってフランジ１６の前部ボルト孔１７に枢支し、後方のアイ８をボルト１１によってシャックル１２の一端部に枢支し、該シャックル１２の他端部をフランジ１６の後部ボルト孔１８にボルト１４によって枢支している。   Further, a front bolt hole 17 and a rear bolt hole 18 penetrating in the vehicle width direction are formed in the flange 16, and the eye 7 in front of the leaf spring 6 is pivotally supported by the bolt 9 on the front bolt hole 17 of the flange 16. The rear eye 8 is pivotally supported by one end of the shackle 12 by a bolt 11, and the other end of the shackle 12 is pivotally supported by a bolt 14 in the rear bolt hole 18 of the flange 16.

つまり、リーフスプリング６やシャックル１２などのサスペンション要素の装着部分となるフランジ１６を、アルミニウム合金の押出加工により中空状のサイドレール本体１５に一体的に形成したので、サイドレール横断面が、部分的に閉じるとともにその高さ寸法が大きくなる。   That is, since the flange 16 serving as a mounting portion for the suspension elements such as the leaf spring 6 and the shackle 12 is formed integrally with the hollow side rail body 15 by extrusion of aluminum alloy, the side rail cross section is partially As it closes, the height dimension increases.

よって、剛性を確保しつつ部品点数が削減され、シャシフレームの軽量化と組付工程の合理化を達成することができる。   Therefore, the number of parts can be reduced while ensuring rigidity, and the weight reduction of the chassis frame and the rationalization of the assembly process can be achieved.

また、フランジ１６の前部ボルト孔１７よりも前方部分、後部ボルト孔１８よりも後方部分、あるいは両ボルト孔１７，１８の間の部分を切除すれば、更なる軽量化を図ることができる。   Further, if the front portion of the flange 16 is more forward than the front bolt hole 17, the rear portion of the rear bolt hole 18, or the portion between the bolt holes 17 and 18, further weight reduction can be achieved.

なお、本発明のシャシフレーム構造は、上述した実施の形態のみに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において変更を加え得ることは勿論である。   It should be noted that the chassis frame structure of the present invention is not limited to the above-described embodiment, and can of course be modified without departing from the gist of the present invention.

本発明のシャシフレーム構造は、様々な車種に適用できる。   The chassis frame structure of the present invention can be applied to various vehicle types.
