Description
しかし特許文献１の車体構造では、センターサイドメンバ３２にサスペンションメンバ１３の前後方向延設部４５が接続されている。このため、センターサイドメンバ３２は、車両旋回時にサスペンションメンバ１３に伝達される車幅方向成分を有する荷重（車両の遠心力や慣性力など）や振動を、サスペンションメンバ１３の前後方向延設部４５を介して受けることになる。しかしながら、特許文献１では、かかる荷重や振動の軽減のための工夫が特になされていない。そのため、車両旋回時などに発生するサスペンションメンバ１３（サスペンションフレーム）およびフロアパネルの振動を抑制することができず、車両の操舵安定性およびＮＶ特性を向上させることが困難である。 However, in the vehicle body structure of Patent Document 1, the longitudinally extending portion 45 of the suspension member 13 is connected to the center side member 32. Therefore, the center side member 32 transfers loads (such as centrifugal force and inertial force of the vehicle) and vibrations having a vehicle width direction component to the suspension member 13 when the vehicle turns, to the longitudinally extending portion of the suspension member 13. It will be received through 5 . However, in Patent Document 1, no particular measures are taken to reduce such loads and vibrations. Therefore, it is not possible to suppress vibrations of the suspension member 13 (suspension frame) and the floor panel that occur when the vehicle turns, and it is difficult to improve the steering stability and NV characteristics of the vehicle.
このため、フロントサスペンションフレーム１０６からサスフレ固定部１２６Ａ、１２８Ａを介してフロアサイドメンバ１２２Ａ、１２４Ａの第２部位１３８Ａ、１４０Ａに伝達された荷重や振動を、第２部位１３８Ａ、１４０Ａの後端部１８０Ａ、１８２Ａを介して、第１部位１３４Ａ、１３６Ａおよびロアクロスメンバ１６４Ａに伝達して分散させることができる。 Therefore, the load and vibration transmitted from the front suspension frame 106 to the second parts 138A, 140A of the floor side members 122A, 124A via the suspension fixing parts 126A, 128A are transferred to the rear end part 180A of the second parts 138A, 140A. , 182A, and can be transmitted and distributed to the first portions 134A, 136A and the lower cross member 164A.
このため、フロントサスペンションフレーム１０６からサスフレ固定部１２６Ｂ、１２８Ｂを介してフロアサイドメンバ１２２Ｂ、１２４Ｂの第２部位１３８Ｂ、１４０Ｂに伝達された荷重や振動を、第２部位１３８Ｂ、１４０Ｂの後端部１８０Ｂ、１８２Ｂからロアクロスメンバ１６４Ｂの両端部２２４、２２６に伝達して、第１部位１３４Ｂ、１３６Ｂおよびロアクロスメンバ１６４Ｂに分散させることができる。 Therefore, the load and vibration transmitted from the front suspension frame 106 to the second parts 138B, 140B of the floor side members 122B, 124B via the suspension fixing parts 126B, 128B are transferred to the rear end part 180B of the second parts 138B, 140B. , 182B to both ends 224, 226 of the lower cross member 164B, and can be distributed to the first portions 134B, 136B and the lower cross member 164B.
このため、フロントサスペンションフレーム１０６からサスフレ固定部１２６Ｃ、１２８Ｃを介してフロアサイドメンバ１２２Ｃ、１２４Ｃの第１部位１３４Ｃ、１３６Ｃに伝達された荷重や振動を、第１部位１３４Ｃ、１３６Ｃの後端部２３２、２３４からサイドシル１４２、１４４およびロアクロスメンバ１６４Ｃに伝達して分散させることができる。 Therefore, the loads and vibrations transmitted from the front suspension frame 106 to the first parts 134C, 136C of the floor side members 122C, 124C via the suspension fixing parts 126C, 128C are transferred to the rear end parts 234C, 136C of the first parts 134C, 136C. , 234 to the side sills 142, 144 and the lower cross member 164C.
