Title: (EN) Vehicle underbody structure comprising reinforcement element between longitudinal beam and lowerside sill part
(ZH) 在纵梁与下边梁部分之间包括加强元件的车辆底部结构
Abstract: front page image
(EN) A vehicle underbody structure comprises a floor panel (1), at least one longitudinal beam (2) extending in a longitudinal direction of the vehicle under said floor panel (1) and at least one lowersidesill part (4) extending in the longitudinal direction adjacent to the floor panel (1), the vehicle underbody structure further comprising at least one reinforcement element (6) extending in a transversal direction, substantially perpendicular to the longitudinal direction, said reinforcement element (6) extending under the floor panel (1) and being attached at one of its transversal ends to the longitudinal beam (2) and at the other of its transversal ends to the lowerside sill part (4). The reinforcement element (6) is made of a press hardened steel part having a tensile strength higher or equal to 1200 MPa.
(ZH) 一种车辆底部结构,车辆底部结构包括底板面板(1)、在所述底板面板(1)下方沿车辆的纵向方向延伸的至少一个纵梁(2)以及邻近于底板面板(1)沿纵向方向延伸的至少一个下边梁部分(4),车辆底部结构还包括沿与纵向方向大致垂直的横向方向延伸的至少一个加强元件(6),所述加强元件(6)在底板面板(1)下方延伸,并且所述加强元件在加强元件的横向端部中的一个横向端部处附接至纵梁(2)并且在加强元件的横向端部中的另一个横向端部处附接至下边梁部分(4)。加强元件(6)由拉伸强度高于或等于1200MPa的压淬钢部件制成。
