The invention relates to the technical field of automobiles, in particular to a longitudinal beam assembly and an automobile chassis. The longitudinal beam assembly comprises a longitudinal beam and a mounting tower which are integrally formed, and the mounting tower is mounted on the longitudinal beam; the longitudinal beam is provided with a first suspension mounting part, and the first suspension mounting part is used for mounting a suspension lower swing arm; a shock absorber mounting part and a second suspension mounting part are arranged on the mounting tower, and the shock absorber mounting part is used for mounting a shock absorber; and the second suspension mounting part is used for mounting a suspension upper swing arm. According to the longitudinal beam assembly and the automobile chassis provided by the embodiment of the invention, the suspension upper swing arm mounting part and the shock absorber mounting part are integrated on the longitudinal beam and are integrally formed with the longitudinal beam, so that mounting errors in the additional mounting process between the suspension upper swing arm mounting part and the shock absorber mounting part and the longitudinal beam are avoided; the position precision of the upper swing arm mounting part and the shock absorber mounting part relative to the longitudinal beam is improved, the manufacturing process of the longitudinal beam assembly is simplified, and the manufacturing cost of the longitudinal beam assembly is reduced.

    本申请涉及汽车的技术领域,尤其涉及一种纵梁总成及汽车底盘。纵梁总成包括一体成型的纵梁和安装塔,安装塔安装在纵梁上;纵梁设有第一悬架安装部,第一悬架安装部用于安装悬架下摆臂;安装塔上设有减震器安装部和第二悬架安装部,减震器安装部用于安装减震器;第二悬架安装部用于安装悬架上摆臂。本申请实施例提供的一种纵梁总成及汽车底盘,其通过将悬架上摆臂安装部和减震器安装部集成到纵梁上,并与纵梁一体成型,避免了悬架上摆臂安装部和减震器安装部与纵梁之间另行安装过程中的安装误差,提高了上摆臂安装部和减震器安装部相对于纵梁的位置精度,简化了纵梁总成的制造工艺和降低了纵梁总成的制造成本。
