The invention belongs to the technical field of automobile parts, and particularly relates to a floor rear longitudinal beam. Comprising a cast aluminum base and a stamping bridging piece, the stamping bridging piece is fixed to the cast aluminum base, a longitudinal beam sealing piece is fixed to the top of the stamping bridging piece, and the shape and the structure of the floor rear longitudinal beam formed after the cast aluminum base and the stamping bridging piece are fixed together are the same as those of a conventional floor rear longitudinal beam; under the condition that the existing arrangement condition of the whole vehicle is not changed, weight reduction and performance improvement can be achieved, and meanwhile connection with the front floor and the longitudinal beam rear section does not damage a conventional technical scheme in the prior art.
本发明属于汽车零部件技术领域,具体涉及一种地板后纵梁;包括铸铝基座和冲压桥接件,其中冲压桥接件固定在铸铝基座上,纵梁封闭件固定在冲压桥接件顶部,且铸铝基座和冲压桥接件固定在一起后形成的地板后纵梁的形状和构造与常规地板后纵梁相同;在不改变现有整车布置条件的情况下,能够实现降重并提升性能,同时与前地板、纵梁后段的连接也不破坏现有技术中的常规技术方案。
