The present application relates to the technical field of automobiles, and, 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, wherein 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 lower suspension swing arm. A shock absorber mounting part and a second suspension mounting part are provided on the mounting tower, wherein the shock absorber mounting part is used for mounting a shock absorber, and the second suspension mounting part is used for mounting an upper suspension swing arm. In the longitudinal beam assembly and the automobile chassis provided in the embodiments of the present application, the upper suspension swing arm mounting part and the shock absorber mounting part are integrated on and integrally formed with the longitudinal beam, such that a mounting error caused by a process of separately mounting the upper suspension swing arm mounting part and the shock absorber mounting part to the longitudinal beam is prevented, thereby improving the precision of positioning the upper swing arm mounting part and the shock absorber mounting part relative to the longitudinal beam, simplifying the manufacturing process of the longitudinal beam assembly, and reducing the manufacturing cost of the longitudinal beam assembly.
