【発明の属する技術分野】本発明は車両の下部車体構造に係り、特に、車体床部にトンネル部が形成さた車両の下部車体構造に関する。 The present invention relates to relates to a vehicle bottom structure of a vehicle, particularly to the lower vehicle body structure of a vehicle tunnel portion is formed on the vehicle body floor.

【0002】 [0002]

【従来の技術】従来、車体床部にトンネル部が形成さた車両の下部車体構造の一例としては、特開平3−126 Conventionally, as an example of the lower vehicle body structure of a vehicle tunnel portion is formed on the vehicle body floor, JP 3-126
779号に示される構造が知られている。 Structure is known as shown in Patent 779.

【0003】図5に示される如く、この車両の下部車体構造では、車体床部の車幅方向中央部に車両前後方向へ沿って形成さたトンネル部70内を上下に仕切る部材7 [0003] As shown in FIG. 5, the lower vehicle body structure of the vehicle, separates the tunnel portion 70 formed along the vehicle longitudinal direction in the vehicle width direction central portion of the vehicle body floor in a vertical member 7
2を設け、トンネル部70の上部に閉断面部74を形成することによって、トンネル部70の強度と車体の前後方向の強度を増大させている。 2 is provided, by forming the closed cross-section portion 74 to the upper portion of the tunnel portion 70, thereby increasing the strength of the longitudinal strength and the body of the tunnel portion 70. また、左右のロッカ76 In addition, the left and right of the rocker 76
(サイドシルともいう)に両端部が結合されたフロアクロスメンバ78をトンネル部70に沿って立ち上がらせ、トンネル部70上部において、閉断面部74に結合することによって、車両前後方向及び車幅方向のフロア面80の強度を増大させている。 Allowed rise along the floor cross member 78 having both ends coupled to (also referred to as side sills) the tunnel portion 70, the tunnel portion 70 the upper, by binding to closed-section portion 74, the vehicle front-rear direction and the vehicle width direction and it increases the strength of the floor surface 80.

【課題を解決するための手段】請求項1記載の本発明は、車体床部の車幅方向中央部に車両前後方向へ沿って形成さたトンネル部と、車体床部の前記トンネル部の車幅方向両側に車両前後方向へ沿って設けられた左右一対のアンダリインフォースと、を有する車両の下部車体構造であって、前記アンダリインフォースに対して車体床部に沿って車両斜め前方略45度方向に延びる線上に前記トンネル部を跨いで左右の車体床部を連結する荷重伝達部材を設けたことを特徴としている。 The present invention SUMMARY OF THE INVENTION The first aspect, a tunnel portion formed along the vehicle longitudinal direction in the vehicle width direction central portion of the vehicle body floor, the car of the tunnel portion of the vehicle body floor a lower body structure of a vehicle having a pair of left and right under reinforcement provided on both widthwise sides along the vehicle longitudinal direction, the vehicle diagonally forward approximately 45 degrees along the vehicle body floor to the under reinforcement It is characterized in across the tunnel portion to the provision of the load transmission member connecting the car body floor of the left and right on a line extending.

【0007】従って、左右何方か一方のアンダリインフォースに衝撃力が作用すると、この衝撃力によって、車体床部には、衝撃力が作用したアンダリインフォースに対して車体床部に沿って車両斜め前方略45度方向に延びる線上に引っ張り場が形成される。 Accordingly, when an impact force to the right and left something towards or the other under reinforcement acts, this impact force, the vehicle body floor, the vehicle diagonally forward substantially along the vehicle body floor against under reinforcement where impact force is applied tensile park line is formed extending in the 45 ° direction. この引っ張り場に沿った方向には、 車両斜め前方略45度方向に延びる荷<br>重伝達部材が設けられており、アンダリインフォースを介してトンネル部を挟んで一方の床部に入力された衝撃力は、荷重伝達部材を介してトンネル部を挟んで他方の床部に確実に伝達される。 The direction along the tension field, load <br> heavy transmission member extending in a vehicle diagonally forward approximately 45 ° direction is provided with, is input to one of the floor across the tunnel portion via the under reinforcement impact force is reliably transmitted to the other floor across the tunnel portion via the load transmission member.

【0008】請求項2記載の本発明は、車体床部の車幅方向中央部に車両前後方向へ沿って形成さたトンネル部と、車体床部の前記トンネル部の車幅方向両側に車両前後方向へ沿って設けられた左右一対のアンダリインフォースと、車体床部の車幅方向両端部に車両前後方向へ沿って設けられた左右一対のロッカと、車体床部に車幅方向に沿って設けられ両端部が前記左右一対のロッカに結合されたフロアクロスメンバと、を有する車両の下部車体構造であって、前記アンダリインフォース後端部と、 [0008] According to a second aspect of the invention, a tunnel portion formed along the vehicle longitudinal direction in the vehicle width direction central portion of the vehicle body floor, the vehicle back and forth in the vehicle width direction on both sides of the tunnel portion of the vehicle body floor a pair of left and right under reinforcement provided along the direction, a pair of left and right rocker provided on both vehicle transverse direction end portion of the vehicle body floor portion along the vehicle longitudinal direction, is provided along a vehicle width direction to the vehicle floor a floor cross member having both ends coupled to the pair of left and right rocker is, a lower vehicle body structure of a vehicle having, with the under reinforcement rear end,
前記フロアクロスメンバと前記アンダリインフォースとの交差部と、のうちの少なくと一方から車体床部に沿って車両斜め前方略45度方向に延びる線上に前記トンネル部を跨いで左右の車体床部を連結する荷重伝達部材を設けたことを特徴としている。 And intersections of the under reinforcement and the floor cross member, the less the vehicle body floor of the left and right across the tunnel portion on a line extending in the vehicle diagonally forward approximately 45 degrees along the vehicle body floor from one of the It is characterized in that a load transmission member for connecting.

【0009】従って、左右何方か一方のアンダリインフォースに車両前方から衝撃力が作用すると、この衝撃力によって、車体床部には衝撃力が作用したアンダリインフォースに対して車両斜め前方略45度方向に延びる線上に引っ張り場が形成される。 Accordingly, when an impact force from the front of the vehicle to the right and left something towards or the other under reinforcement acts, this impact force, the vehicle diagonally forward approximately 45 ° direction relative to the under reinforcement an impact force is exerted on the vehicle body floor tensile park line is formed to extend. この引っ張り場が最も荷重を受け易いアンダリインフォース後端部と、フロアクロスメンバとアンダリインフォースとの交差部と、のうちの少なくと一方から延びる引っ張り場に沿った方向には、 車両斜め前方略45度方向に延びる荷重伝達部材が設けられている。 And the tension field is most load the susceptible under reinforcement rear end, and the intersection of the floor cross member and under reinforcement, the less the direction along the pulling-field extends from one of the vehicle diagonally forward approximately 45 load transmission member extending degree direction. このため、アンダリインフォースを介してトンネル部を挟んで一方の床部に入力された衝撃力は、荷重伝達部材を介してトンネル部を挟んで他方の床部に最も効果的に伝達される。 Therefore, the impact is input to one of the floor across the tunnel portion via the under reinforcement force is most effectively transmitted to the other floor across the tunnel portion via the load transmission member.
