Description

【０００１】
【発明の属する技術分野】
本発明は、車両の前部においてスタビライザを強固に支持するための構成に関する。
【０００２】
【従来の技術】
車両前部における従来のスタビライザ支持構造は、図２に例示されているように、フロントクロスメンバ１の左右端部における車両前方側にそれぞれスタビライザブラケット２の後端縁が溶着され、スタビライザブラケット２の前面３に取付け具４によりスタビライザ５の左右端部がそれぞれ支持されているので、車体のロール時にはスタビライザ５を介してスタビライザブラケット２に大きな負荷がかかるため、スタビライザ５の取付け点であるスタビライザブラケット前面３とフロントクロスメンバ１に対するスタビライザブラケット２の溶着部との車両前後方向オフセットＡを小さくする方がスタビライザブラケット２の強度上有利となるが、このオフセットＡを小さくすると、車両の衝突時にスタビライザブラケット２の変形によって衝撃エネルギを吸収させるためには不利になるという問題があった。
【０００３】
また、フロントクロスメンバ１の左右端部における車両前方側には、図示しないラジエータを取り付けるためそれぞれラジエータブラケット６の後縁が溶着されているが、ラジエータブラケット６に十分な剛性を確保するためには、ラジエータブラケット６自身を比較的大型とする必要があって、ラジエータブラケット６の重量やコストを増大させる不具合があった。
【０００４】
また、特開平８−１５６５５４号公報に記載されたフロントスタビライザの支持構造においては、車両におけるクロスメンバの両端部近傍に、フロントデフを支持するためのデフマウントブラケットが固定され、デフマウントブラケットにスタビライザの枢軸部が取り付けられているが、この場合には、スタビライザ自体を支持するためのブラケットがとくに設けられていないと共に、車両の衝突時における衝撃エネルギの吸収について何らの配慮もみられない。
【０００５】
【発明が解決しようとする課題】
本発明は、車両の前部におけるスタビライザを強固に支持することができると共に、車両の衝突時に衝撃エネルギを比較的多く吸収できるスタビライザ支持構造を提供しようとするものである。
【０００６】
【課題を解決するための手段】
このため、本発明にかかるスタビライザ支持構造は、車両の前部に設置されて車幅方向に延びるフロントクロスメンバと、車両後方に開口する断面略コ字状であって上記フロントクロスメンバの左右端部における車両前方側にそれぞれ後端縁が固着されると共に前面にスタビライザが取り付けられるスタビライザブラケットと、上記スタビライザブラケットの上方を覆って上記スタビライザブラケットの上端部に固着されると共に後端縁が上記フロントクロスメンバに固着された補機ブラケットとを有している。
【０００７】
すなわち、断面略コ字状スタビライザブラケットの上方が補機ブラケットで覆われて、スタビライザブラケットの上端部に補機ブラケットが固着されることにより、両ブラケットが一体化されて箱形に構成されているため、両ブラケットの剛性が格段に高められることとなるので、スタビライザが取り付けられたスタビライザブラケット前面とフロントクロスメンバの車両前方側に固着されたスタビライザブラケット後端縁との車両前後方向オフセットを容易に大きく設定することが可能となり、また、補機ブラケットを無理なく小型化できるようになる。
【０００８】
【発明の実施の形態】
以下、本発明の実施形態例について説明する。
図１において、車両の左右でそれぞれサイドメンバ１０が車両前後方向に延び、両サイドメンバ１０の前端が車幅方向に延びる丸パイプ状のフロントクロスメンバ１１により連結されていると共に、各サイドメンバ１０から下方へ延びるロアアームブラケット１２に車幅方向へ延びるクロスメンバ１３の左右端部がそれぞれ連結されて、フロントクロスメンバ１１から車両後方へ間隔をおいてクロスメンバ１３により両サイドメンバ１０が連結されている。
【０００９】
フロントクロスメンバ１１の左右端部には、ロアアームブラケット１２と共にダブルウイッシュボーン型サスペンションの二股ロアアーム１４を取り付けるためのロアアームブラケット１５と、図示しないフロントデフを支持するためのデフマウントブラケット１６とがそれぞれ固着されている。
【００１０】
また、フロントクロスメンバ１１の左右端部における車両前方側には、車両後方に開口する断面略コ字状のスタビライザブラケット１７と、スタビライザブラケット１７の上方を覆ってスタビライザブラケット１７の上端部に溶着された補機ブラケット１８とがそれぞれ配置され、箱形に一体化されたスタビライザブラケット１７及び補機ブラケット１８のうち、各スタビライザブラケット１７の後端縁がそれぞれフロントクロスメンバ１１、ロアアームブラケット１５及びデフマウントブラケット１６に溶着されていると共に、各補機ブラケット１８の後端縁がそれぞれフロントクロスメンバ１１に溶着されており、各スタビライザブラケット１７の前面１９には、車幅方向に延びるスタビライザ２０が取付け具２１により取り付けられている一方、補機ブラケット１８には図示しないラジエータ、オイルクーラ、ターボ付きエンジンの吸気用インタクーラ、あるいは、冷房用冷媒コンデンサ等の補機が取り付けられている。
【００１１】
さらに、各サイドメンバ１０には、上記ダブルウイッシュボーン型サスペンションの図示しない二股アッパーアームを取り付けるためのアッパーアームブラケット２２が車両前後方向に間隔をおいてそれぞれ固着されていると共に、車幅方向外側へ延びるバンプストッパブラケット２３が固着され、バンプストッパブラケット２３の先端に設けられた受け板２４と、二股ロアアーム１４の上面に設置されたバンプゴム２５とが略上下に配置されて、二股ロアアーム１４の揺動に伴う受け板２４及びバンプゴム２５の衝突により二股ロアアーム１４の上方変位が制約されることとなる。
【００１２】
また、クロスメンバ１３にはデフマウントブラケット２６が固着されていて、フロントクロスメンバ１１に固着された両デフマウントブラケット１６とデフマウントブラケット２６、及び、クロスメンバ１３に固着された図示しないブラケットにより、フロントデフを支持するように構成されている。
【００１３】
すなわち、断面略コ字状スタビライザブラケット１７の上方が補機ブラケット１８で覆われて、両ブラケット１７、１８が固着されることにより、両ブラケット１７、１８が一体化されて箱形に構成されることとなるため、両ブラケット１７、１８の各後端縁がそれぞれフロントクロスメンバ１１等に溶着されたとき、両ブラケット１７、１８の剛性は格段に高められることとなる。
【００１４】
従って、車体のロール時には、フロントクロスメンバ１１の車両前方側に溶着されたスタビライザブラケット１７にスタビライザ２０を介して大きな負荷がかかっても、スタビライザ２０が取り付けられたスタビライザブラケット前面１９と、スタビライザブラケット１７の後端縁との車両前後方向オフセットＢを容易に大きく設定することが可能となり、このため、車両の衝突時にはスタビライザブラケット１７が車両前後方向に比較的大きく変形して、衝撃エネルギを多く吸収することが可能となり、この面から乗員を効果的に保護することができるようになる。
【００１５】
また、補機ブラケット１８の剛性増加により、補機ブラケット１８を容易に小型化させることができると同時に、フロントクロスメンバ１１の車両前方側に対する補機ブラケット１８後端縁の溶着部分も少なくてすむため、補機ブラケット１８の重量軽減とコストダウンとを簡単に実現させることができる長所がある。
【００１６】
【発明の効果】
本発明にかかるスタビライザ支持構造にあっては、スタビライザブラケットと補機ブラケットとが固着されて箱形に構成されることにより、両ブラケットの剛性がそれぞれ格段に高められ、従って、スタビライザが取り付けられたスタビライザブラケット前面とフロントクロスメンバの車両前方側に固着されたスタビライザブラケット後端縁との車両前後方向オフセットを容易に大きく設定することが可能となるので、車両の衝突時にはスタビライザブラケットが車両前後方向に比較的大きく変形し、衝撃エネルギを多く吸収することができて、乗員を効果的に保護することができるようになると同時に、補機ブラケットを容易に小型化させることができるため、補機ブラケットの重量軽減とコストダウンとを簡単に実現させることが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a configuration for firmly supporting a stabilizer at a front portion of a vehicle.
[0002]
[Prior art]
As shown in FIG. 2, the conventional stabilizer support structure in the front portion of the vehicle has the rear end edges of the stabilizer bracket 2 welded to the front side of the vehicle at the left and right ends of the front cross member 1. Since the left and right end portions of the stabilizer 5 are supported on the front surface 3 by the attachment 4, a large load is applied to the stabilizer bracket 2 through the stabilizer 5 when the vehicle body is rolled, so the front surface of the stabilizer bracket that is the attachment point of the stabilizer 5 It is advantageous in terms of strength of the stabilizer bracket 2 to reduce the vehicle longitudinal direction offset A between the welded portion of the stabilizer bracket 2 to the front cross member 1 and the front cross member 1, but if this offset A is reduced, the stabilizer bracket 2 will be reduced when the vehicle collides. By deformation of There is a problem that it is disadvantageous in order to absorb the impact energy.
[0003]
In addition, the rear edge of the radiator bracket 6 is welded to the front side of the vehicle at the left and right ends of the front cross member 1 in order to attach a radiator (not shown), but in order to ensure sufficient rigidity for the radiator bracket 6. The radiator bracket 6 itself needs to be relatively large, and there is a problem that the weight and cost of the radiator bracket 6 are increased.
[0004]
In the front stabilizer support structure described in Japanese Patent Application Laid-Open No. 8-156554, a differential mount bracket for supporting the front differential is fixed in the vicinity of both ends of the cross member in the vehicle, and the stabilizer is attached to the differential mount bracket. In this case, a bracket for supporting the stabilizer itself is not particularly provided, and no consideration is given to absorption of impact energy at the time of a vehicle collision.
[0005]
[Problems to be solved by the invention]
The present invention is intended to provide a stabilizer support structure that can firmly support the stabilizer at the front portion of the vehicle and can absorb a relatively large amount of impact energy when the vehicle collides.
[0006]
[Means for Solving the Problems]
For this reason, the stabilizer support structure according to the present invention includes a front cross member that is installed at the front of the vehicle and extends in the vehicle width direction, and has a substantially U-shaped cross section that opens to the rear of the vehicle. A stabilizer bracket to which a rear end edge is fixed to the front side of the vehicle and a stabilizer is attached to the front surface, and a stabilizer bracket that covers the upper portion of the stabilizer bracket and is fixed to an upper end portion of the stabilizer bracket. And an accessory bracket fixed to the cross member.
[0007]
That is, the upper part of the substantially U-shaped stabilizer bracket is covered with the auxiliary bracket, and the auxiliary bracket is fixed to the upper end of the stabilizer bracket, so that both brackets are integrated into a box shape. As a result, the rigidity of both brackets is significantly increased, and therefore the vehicle front-rear direction offset between the front surface of the stabilizer bracket to which the stabilizer is attached and the rear end edge of the stabilizer bracket fixed to the front side of the front cross member is easily achieved. It becomes possible to set large, and the accessory bracket can be made compact without difficulty.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described.
In FIG. 1, side members 10 extend in the vehicle front-rear direction on the left and right sides of the vehicle, and the front ends of both side members 10 are connected by a round pipe-shaped front cross member 11 extending in the vehicle width direction. The left and right end portions of the cross member 13 extending in the vehicle width direction are respectively connected to the lower arm bracket 12 extending downward from the vehicle, and both side members 10 are connected to each other by the cross member 13 at a distance from the front cross member 11 to the rear of the vehicle. Yes.
[0009]
A lower arm bracket 15 for attaching a bifurcated lower arm 14 of a double wishbone type suspension together with a lower arm bracket 12 and a differential mount bracket 16 for supporting a front differential (not shown) are fixed to the left and right ends of the front cross member 11, respectively. Has been.
[0010]
Further, on the vehicle front side at the left and right end portions of the front cross member 11, a stabilizer bracket 17 having a substantially U-shaped cross section that opens to the rear of the vehicle, and an upper end portion of the stabilizer bracket 17 that covers the top of the stabilizer bracket 17 are welded. Among the stabilizer bracket 17 and the accessory bracket 18 that are respectively arranged in a box shape, the rear end edges of the stabilizer brackets 17 are respectively the front cross member 11, the lower arm bracket 15, and the differential mount. The auxiliary bracket 18 is welded to the bracket 16 and the rear edge of each accessory bracket 18 is welded to the front cross member 11. A stabilizer 20 extending in the vehicle width direction is attached to the front surface 19 of each stabilizer bracket 17. Attached by 21 That while the radiator not shown in accessory bracket 18, an oil cooler, an intercooler for the intake of turbocharged engines or, auxiliary equipment such as cooling refrigerant condenser is attached.
[0011]
Further, an upper arm bracket 22 for attaching a bifurcated upper arm (not shown) of the double wishbone suspension is fixed to each side member 10 at intervals in the vehicle front-rear direction and outward in the vehicle width direction. The extending bump stopper bracket 23 is fixed, and a receiving plate 24 provided at the tip of the bump stopper bracket 23 and a bump rubber 25 installed on the upper surface of the bifurcated lower arm 14 are arranged substantially vertically so that the bifurcated lower arm 14 swings. The upper displacement of the bifurcated lower arm 14 is restricted by the collision of the receiving plate 24 and the bump rubber 25 accompanying the above.
[0012]
Further, a differential mount bracket 26 is fixed to the cross member 13, and both the differential mount bracket 16 and the differential mount bracket 26 fixed to the front cross member 11, and a bracket (not shown) fixed to the cross member 13, It is configured to support the front differential.
[0013]
That is, the upper part of the substantially U-shaped stabilizer bracket 17 is covered with the accessory bracket 18 and the brackets 17 and 18 are fixed to each other so that the brackets 17 and 18 are integrated into a box shape. Therefore, when the rear end edges of the brackets 17 and 18 are welded to the front cross member 11 and the like, the rigidity of the brackets 17 and 18 is remarkably enhanced.
[0014]
Therefore, when the vehicle body is rolled, even if a large load is applied to the stabilizer bracket 17 welded to the front side of the front cross member 11 via the stabilizer 20, the stabilizer bracket front surface 19 to which the stabilizer 20 is attached, and the stabilizer bracket 17. The vehicle front-rear direction offset B with respect to the rear end edge can be easily set large. For this reason, when the vehicle collides, the stabilizer bracket 17 is deformed relatively greatly in the vehicle front-rear direction and absorbs a lot of impact energy. And it becomes possible to effectively protect the passenger from this aspect.
[0015]
Further, the auxiliary bracket 18 can be easily reduced in size by increasing the rigidity of the auxiliary bracket 18, and at the same time, the welded portion of the rear end edge of the auxiliary bracket 18 to the front side of the front cross member 11 can be reduced. Therefore, there is an advantage that weight reduction and cost reduction of the accessory bracket 18 can be easily realized.
[0016]
【The invention's effect】
In the stabilizer support structure according to the present invention, the stabilizer bracket and the accessory bracket are fixed to form a box shape, so that the rigidity of both brackets is remarkably increased, and thus the stabilizer is attached. The vehicle front-rear direction offset between the front of the stabilizer bracket and the rear end edge of the stabilizer bracket fixed to the front side of the front cross member can be easily set large. It can be deformed relatively greatly, can absorb a lot of impact energy, and can effectively protect the occupant, and at the same time, the accessory bracket can be easily downsized. It is possible to easily realize weight reduction and cost reduction That.
