Vehicle, structural part of which comprises element with varying stiffness

The invention relates to a vehicle comprising a structural part (SV) comprising an element (ES) comprising a first portion (P1) and a second portion (P2), which are elongated from one another at the location of a weld line (LS) and have a first stiffness and a second stiffness, respectively, which is strictly greater than the first stiffness. The first part (P1) and the second part (P2) together define a receptacle (LI) for accommodating a reinforcing insert (IR) extending on both sides of the weld line (LS) in order to keep the weld line (LS) away from the stress experienced by the element (ES) in the event of a collision while moving the stress into the first part (P1). 本发明涉及一种车辆，所述车辆包括结构件(SV)，所述结构件包括元件(ES)，所述元件包括第一部分(P1)和第二部分(P2)，所述第一部分和所述第二部分在焊接线(LS)位置处相互延长并且分别具有第一刚度和第二刚度，所述第二刚度严格地大于所述第一刚度。所述第一部分(P1)和所述第二部分(P2)共同限定出容置加固插件(IR)的容置部(LI)，所述加固插件在所述焊接线(LS)两侧延伸，以便在发生碰撞的情况下使所述焊接线(LS)远离由所述元件(ES)经受的应力，同时使所述应力挪到所述第一部分(P1)中。
