Description

本発明は、自動車においてサスペンション装置を車体に連結するために用いられる、サスペンションメンバに関するものである。   The present invention relates to a suspension member used for connecting a suspension device to a vehicle body in an automobile.

従来、サスペンション装置を車体に連結するためのサスペンションメンバ５１としては、たとえば特許文献１（図５）に記載されているように、車体側のサイドシル５２に連結された左右一対のサイドフレーム５３に、車両前後方向に所定の間隔をおいて、三対のマウント部５４、５５、５６（インシュレーターを内蔵する円筒状をなす取り付け部）を介して設ける形態のものが提案されている。
特開２００２−１３７６１５号公報 Conventionally, as a suspension member 51 for connecting a suspension device to a vehicle body, for example, as described in Patent Document 1 (FIG. 5), a pair of left and right side frames 53 connected to a side sill 52 on the vehicle body side, There has been proposed a configuration in which three pairs of mount portions 54, 55, and 56 (cylindrical mounting portions containing an insulator) are provided at predetermined intervals in the vehicle front-rear direction.
JP 2002-137615 A

ところがこのような形態のサスペンションメンバ５１においては、車体側のサイドフレーム５３の後端部に図示しないバンパーが設けられた構造のもと、後面衝突が発生した場合に、バンパーから、サスペンションメンバ５１およびサイドフレーム５３を経由して車体のサイドシル５２に後面衝突による圧縮力が伝達されることになり、特にはマウント部５４よりも車両前方側においてはその圧縮力をサイドフレーム５３のみで負担するため、マウント部５４よりも車両前方側に位置するサイドフレーム５３が車両前後方向に圧縮されて、座屈により車両前後方向に縮んでしまうという問題点があった。特に、サイドフレーム５３の前端部から、車両前方のマウント部５４との間に燃料タンクが艤装配置されているような場合、マウント部５４よりも車両前方側のサイドフレーム５３が座屈により縮んでしまうと、燃料タンクが破損するおそれがあるため、サイドフレーム５３の剛性を上げる必要があり、車両の重量の増加、コストの増大を招く要因となっていた。また、サイドフレーム５３が座屈により縮んでも、他の構造物が燃料タンクに干渉しないようにするため、レイアウト上の制約を受けるというデメリットもあった。   However, in the suspension member 51 having such a configuration, a bumper (not shown) is provided at the rear end portion of the side frame 53 on the vehicle body side. When a rear collision occurs, the suspension member 51 and the suspension member 51 The compressive force due to the rear collision is transmitted to the side sill 52 of the vehicle body via the side frame 53, and in particular, the compressive force is borne only by the side frame 53 on the front side of the vehicle relative to the mount portion 54. There is a problem in that the side frame 53 positioned on the vehicle front side of the mount portion 54 is compressed in the vehicle front-rear direction and contracts in the vehicle front-rear direction due to buckling. In particular, when a fuel tank is installed between the front end portion of the side frame 53 and the mount portion 54 in front of the vehicle, the side frame 53 on the vehicle front side of the mount portion 54 contracts due to buckling. As a result, the fuel tank may be damaged, so that it is necessary to increase the rigidity of the side frame 53, which increases the weight of the vehicle and increases the cost. In addition, even if the side frame 53 contracts due to buckling, there is a demerit that the structure is restricted in order to prevent other structures from interfering with the fuel tank.

本発明の目的は、上述した課題を解決することであり、後面衝突が発生した場合でも、車体側のサイドフレームが座屈により変形することを抑制することができる、サスペンションメンバを提供することにある。   An object of the present invention is to solve the above-described problem, and to provide a suspension member that can suppress deformation of a side frame on the vehicle body side due to buckling even when a rear collision occurs. is there.

請求項１に係るサスペンションメンバは、車幅方向中央に関して対称に位置する一対の車両前後方向に延在するサイドメンバと、車幅方向に延びるとともに、当該一対のサイドメンバを連結する一以上のビームとを有してなる、車体とサスペンション装置を連結するサスペンションメンバにおいて、
前記一対のサイドメンバのそれぞれに、車両前後方向に所定の間隔をおいて三つづつのマウント部を設け、三対のマウント部を形成するとともに、最も車両前方側に位置する一対のマウント部をそれぞれ車体側のサイドシルに連結し、それ以外のマウント部を車体側のサイドフレームに連結してなる。 The suspension member according to claim 1 includes a pair of side members extending in the vehicle front-rear direction symmetrically positioned with respect to the center in the vehicle width direction, and one or more beams extending in the vehicle width direction and connecting the pair of side members. In the suspension member that connects the vehicle body and the suspension device,
Each of the pair of side members is provided with three mount portions at predetermined intervals in the vehicle front-rear direction to form three pairs of mount portions, and each of the pair of mount portions located on the most front side of the vehicle. It is connected to the side sill on the vehicle body side, and the other mount part is connected to the side frame on the vehicle body side.

請求項１に係るサスペンションメンバによれば、最も車両前方側に位置する一対のマウント部を車体側のサイドシルに連結しているため、後面衝突が発生した場合に、バンパーから、車体側のサイドシルに伝達される車両前後方向の圧縮力を、車両前後方向の全体にわたって、サスペンションメンバの最も車両後方側のマウント部から最も車両前方側のマウント部との間に延在するサイドメンバとサイドフレームとにより分担して支持することができ、従来の構造のサスペンションメンバを適用することに比べて、前記圧縮力をサイドフレームのみで負担する部分をなくすことができる。これにより、従来の構造で問題となった、サイドフレームの座屈による変形を抑制することができる。   According to the suspension member of the first aspect, since the pair of mount portions located on the most front side of the vehicle are connected to the side sill on the vehicle body side, when a rear collision occurs, from the bumper to the side sill on the vehicle body side. The transmitted compression force in the vehicle front-rear direction is caused by the side members and side frames that extend between the mount portion on the rearmost side of the vehicle and the mount portion on the front side of the vehicle throughout the vehicle front-rear direction. Compared with the application of a suspension member having a conventional structure, it is possible to eliminate the portion where the compression force is borne only by the side frames. Thereby, the deformation | transformation by the buckling of a side frame which became a problem with the conventional structure can be suppressed.

以下、本発明の実施の形態を図面に基づいて説明する。
図１は本発明に係るサスペンションメンバの一実施形態を、斜め上方から見て示す、模式図であり、図２は、上方から見て示す模式図である。
このサスペンションメンバ１は、図１に示すように、車幅方向中央に関して対称に位置する一対の車両前後方向に延在するサイドメンバ２と、車幅方向に延びるとともに、当該一対のサイドメンバ２を連結する一以上のビーム３、４、５とを有してなる、車体とサスペンション装置を連結するサスペンションメンバにおいて、
前記一対のサイドメンバ２それぞれに、車両前後方向に所定の間隔をおいて三つづつのマウント部６、７、８を設け、三対のマウント部を形成するとともに、図２に示すように、最も車両前方側に位置する一対のマウント部６をそれぞれ車体側のサイドシル９に連結し、それ以外のマウント部７、８を車体側のサイドフレーム１０に連結してなることを特徴とする。（請求項１に相当） Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view showing an embodiment of a suspension member according to the present invention as viewed from obliquely above, and FIG. 2 is a schematic view as seen from above.
As shown in FIG. 1, the suspension member 1 includes a pair of side members 2 extending symmetrically in the vehicle front-rear direction and symmetrically positioned with respect to the vehicle width direction center, and extending in the vehicle width direction. In the suspension member that connects the vehicle body and the suspension device, which has one or more beams 3, 4, and 5 to be connected,
Each of the pair of side members 2 is provided with three mount portions 6, 7, 8 at predetermined intervals in the vehicle front-rear direction to form three pairs of mount portions, as shown in FIG. A pair of mount portions 6 positioned on the vehicle front side are respectively connected to a side sill 9 on the vehicle body side, and other mount portions 7 and 8 are connected to a side frame 10 on the vehicle body side. (Equivalent to claim 1)

請求項１に係るサスペンションメンバ１によれば、最も車両前方側に位置する一対のマウント部６を車体側のサイドシル９に連結しているため、後面衝突が発生した場合に、図示しないバンパーから、車体側のサイドシル９に伝達される車両前後方向の圧縮力を、サスペンションメンバ１の最も車両後方側に位置するマウント部８から最も車両前方側に位置するマウント部６との間に延在するサイドメンバ２とサイドフレーム１０とにより分担して支持することができ、これにより、サイドフレーム１０のマウント部７よりも前方側における座屈による変形を抑制して、燃料タンクＦの破損をさらに効果的に防止することができる。   According to the suspension member 1 according to the first aspect, since the pair of mount portions 6 positioned closest to the vehicle front side are connected to the side sill 9 on the vehicle body side, when a rear collision occurs, the bumper (not shown) A side that extends the vehicle longitudinal compression force transmitted to the side sill 9 on the vehicle body side from the mount portion 8 located on the most rear side of the suspension member 1 to the mount portion 6 located on the most front side of the vehicle. The member 2 and the side frame 10 can be shared and supported, thereby suppressing deformation due to buckling in front of the mount portion 7 of the side frame 10 and further effectively damaging the fuel tank F. Can be prevented.

さらに、前記一対のサイドメンバ２のうち、最も車両後方側に位置する一対のマウント部８と、車両前後方向の中間に位置する一対のマウント部７との間に位置する部分を、上方側サイドメンバ２ａと、下方側サイドメンバ２ｂの上下二段のメンバで形成している。（請求項２に相当）
なお、ここでは上方側サイドメンバ２ａと下方側サイドメンバ２ｂはマウント部７とマウント部８との中間位置においてサイドメンバ２の一部をなす上下方向に延びる角状部材２ｃにより連結され、前記ビーム５は、一対の角状部材２ｃを相互に連結している。
請求項２に相当する構成によれば、サスペンションメンバ１自体の車両前後方向の剛性を高めて、後面衝突により図示しないバンパーに入力される力を、上方側サイドメンバ２ａと下方側サイドメンバ２ｂの双方を介して、サイドシル９に効率よく伝達することができるため、サイドフレーム１０のマウント部７よりも前方側における座屈による変形をさらに効果的に抑制して、燃料タンクＦの破損を防止することができる。 Further, of the pair of side members 2, a portion located between the pair of mount portions 8 located closest to the vehicle rear side and the pair of mount portions 7 located in the middle in the vehicle front-rear direction is defined as the upper side side. The member 2a and the lower side member 2b are formed of two upper and lower members. (Equivalent to claim 2)
Here, the upper side member 2a and the lower side member 2b are connected to each other by a rectangular member 2c that extends in the vertical direction and forms a part of the side member 2 at an intermediate position between the mount portion 7 and the mount portion 8. 5 couples the pair of square members 2c to each other.
According to the configuration corresponding to the second aspect, the rigidity of the suspension member 1 itself in the longitudinal direction of the vehicle is increased, and the force input to the bumper (not shown) due to the rear collision is applied to the upper side member 2a and the lower side member 2b. Since both can be efficiently transmitted to the side sill 9, deformation due to buckling in front of the mounting portion 7 of the side frame 10 is further effectively suppressed, and damage to the fuel tank F is prevented. be able to.

つまり、マウント部８と、マウント部７との間に位置する一対のサイドメンバ２を、上方側サイドメンバ２ａと、下方側サイドメンバ２ｂで構成することにより、後面衝突によるエネルギーに対するサスペンションメンバ１の分担分を増やすことができる。これにより、車体側のサイドフレーム１０の後面衝突によるエネルギーの分担分が減少し、よって、サイドフレーム１０の変形も小さくすることができ、マウント部７より前方に位置するサイドフレーム１０の前方部分の変形も抑制して、燃料タンクＦの破損を防止することができる。   In other words, the pair of side members 2 positioned between the mount portion 8 and the mount portion 7 are constituted by the upper side member 2a and the lower side member 2b, so that the suspension member 1 can be protected against energy caused by a rear collision. The share can be increased. Thereby, the share of energy due to the rear surface collision of the side frame 10 on the vehicle body side is reduced, so that the deformation of the side frame 10 can also be reduced, and the front portion of the side frame 10 positioned in front of the mount portion 7 can be reduced. Deformation can also be suppressed and damage to the fuel tank F can be prevented.

加えて、最も車両前方側に位置する一対のマウント部６の車幅方向間隔Ｗ６を、車両前後方向の中間に位置する一対のマウント部７の車幅方向間隔Ｗ７よりも大としている。（請求項３に相当）ここでは、最も車両後方側に位置する一対のマウント部８の車幅方向間隔Ｗ８と前記車幅方向間隔Ｗ７とはほぼ同じ長さとしている。
請求項３に相当する構成によれば、旋回走行時において図示しない車輪に横力が働いた場合に、サスペンションメンバ１の瞬間回転中心Ｃの周りに発生するモーメントを、最も車両前方側に位置するマウント部６から瞬間回転中心Ｃに至る、長尺のモーメントアームＭＡにより拘束することができるため、サスペンションメンバ１のヨー方向の支持剛性を高めて、走行安定性を高めることができる。 In addition, the vehicle width direction interval W6 between the pair of mount portions 6 positioned closest to the vehicle front side is made larger than the vehicle width direction interval W7 between the pair of mount portions 7 positioned in the middle in the vehicle front-rear direction. (Equivalent to Claim 3) Here, the vehicle width direction interval W8 and the vehicle width direction interval W7 of the pair of mount portions 8 located closest to the vehicle rear side are substantially the same length.
According to the configuration corresponding to the third aspect, the moment generated around the instantaneous rotation center C of the suspension member 1 when the lateral force is exerted on the wheel (not shown) during the turn traveling is located on the most front side of the vehicle. Since it can be restrained by the long moment arm MA from the mount portion 6 to the instantaneous rotation center C, the support rigidity in the yaw direction of the suspension member 1 can be increased, and the running stability can be improved.

なお、サイドメンバ２、ビーム３、５は丸パイプ部材で構成され、ビーム４は角パイプ部材で構成されている。上方側サイドメンバ２ａにはＡ形状のアッパーアーム１１が車幅方向外側に突出して揺動自在に設けられ、下方側サイドメンバ２ｂにはトーコントロールリンク１２、トランスバースリンク１３が設けられ、サイドメンバ２のマウント部７近傍には、トレーリングリンク１４が設けられ、これらは図示しないアクスル部材に連結されて、サスペンション装置が構成される。
請求項２に相当する構成は、上方側サイドメンバ２ａがアッパーアーム１１を、下方側サイドメンバ２ｂがロアリンクに相当するトーコントロールリンク１２、トランスバースリンク１３およびトレーリングリンク１４を、それぞれ別個に支持することができるため、アッパーアーム１１とロアリンクを組み合わせたサスペンション装置を構成するに当たっても有利なものである。 The side member 2 and the beams 3 and 5 are constituted by round pipe members, and the beam 4 is constituted by a square pipe member. The upper side member 2a is provided with an A-shaped upper arm 11 projecting outward in the vehicle width direction so as to be swingable. The lower side member 2b is provided with a toe control link 12 and a transverse link 13, and the side member A trailing link 14 is provided in the vicinity of the mount portion 7 of 2 and is connected to an axle member (not shown) to constitute a suspension device.
The structure corresponding to claim 2 is such that the upper side member 2a is the upper arm 11 and the lower side member 2b is the lower link, the toe control link 12, the transverse link 13 and the trailing link 14 separately. Since it can be supported, it is advantageous in constructing a suspension device in which the upper arm 11 and the lower link are combined.

なおここで、最も車両前方側に位置する一対のマウント部６の、前記サイドメンバの延在方向の剛性を、他の方向の剛性に対し、硬くすることが好ましい。（請求項４に相当）
ここでマウント部の剛性とは、マウント部内に内蔵されたインシュレーターの剛性を示すものとする。
これによれば、後面衝突により入力される車両前後方向の力を、サスペンションメンバ１のサイドメンバ３により効果的にサイドシル９に伝達することができ、マウント部７よりも車両前方に位置するサイドフレーム１０が座屈により縮んでしまうことをより効果的に抑制して、燃料タンクＦが破損することを防止することができる。 Here, it is preferable that the rigidity in the extending direction of the side member of the pair of mount portions 6 positioned closest to the front side of the vehicle is harder than the rigidity in the other direction. (Equivalent to claim 4)
Here, the rigidity of the mount portion indicates the rigidity of the insulator built in the mount portion.
According to this, the force in the vehicle front-rear direction input by the rear collision can be effectively transmitted to the side sill 9 by the side member 3 of the suspension member 1, and the side frame positioned in front of the vehicle relative to the mount portion 7. It can suppress more effectively that 10 contracts by buckling and can prevent that the fuel tank F breaks.

図３は、本発明に係わるサスペンションメンバの車体への取り付け態様を車両側方から見て示す模式図である。
サスペンションメンバ１は、マウント部６によりサイドシル９に連結され、マウント部７、８によりサイドフレーム１０に連結される。
車両前後方向に延びるサイドメンバ２は、車両前後方向の中間のマウント部７と車両後方のマウント部８との間で二股状に分岐して、上方側サイドメンバ２ａ、下方側サイドメンバ２ｂを形成している。 FIG. 3 is a schematic view showing a manner in which the suspension member according to the present invention is attached to the vehicle body as seen from the side of the vehicle.
The suspension member 1 is connected to the side sill 9 by the mount portion 6 and is connected to the side frame 10 by the mount portions 7 and 8.
The side member 2 extending in the vehicle front-rear direction is bifurcated between a middle mount portion 7 in the vehicle front-rear direction and a mount portion 8 rearward of the vehicle to form an upper side member 2a and a lower side member 2b. is doing.

図４は、本発明に係わる他のサスペンションメンバの車体への取り付け態様を車両側方から見て示す模式図である。

The suspension member 1 is connected to the side sill 9 by the mount portion 6 and is connected to the side frame 10 by the mount portions 7 and 8.
The side member 2 extending in the vehicle front-rear direction is configured using a round pipe member.

なお、本発明のサスペンションメンバによれば、従来の二対のマウント部をすべてサイドフレームに連結した構造のサスペンションメンバに比して、図２に示したサイドフレーム１０のマウント部７の、後面衝突時の前方への移動量７０％程度低減することが可能である。解析によれば、二対のマウント部を有する上下二段のサイドメンバを有しない従来構造のサスペンションメンバにおいて、マウント部７に相当する部位が後面衝突により１６０ｍｍ前方に移動するのに対し、本実施例（請求項１、２、３を含む構成）ではその移動量を４５ｍｍとすることができた。   According to the suspension member of the present invention, the rear surface collision of the mounting portion 7 of the side frame 10 shown in FIG. 2 is compared with the suspension member having a structure in which two conventional pairs of mounting portions are all connected to the side frame. It is possible to reduce the amount of forward movement by about 70%. According to the analysis, in a suspension member having a conventional structure having two pairs of mount portions and not having two upper and lower side members, a portion corresponding to the mount portion 7 moves forward by 160 mm due to a rear collision. In the example (configuration including claims 1, 2, and 3), the amount of movement could be 45 mm.
