The invention provides an automobile assembly chassis. The automobile assembly chassis comprises a chassis body, a first single-piece assembly and a second single-piece assembly. The first single-piece assembly comprises a plurality of first front axle single-piece assemblies, a plurality of first rear axle single-piece assemblies, a plurality of first mounting hard points and a plurality of second mounting hard points; the second single-piece assembly comprises a plurality of second front axle single-piece assemblies, a plurality of second rear axle single-piece assemblies and a plurality of third installation hard points. The invention further provides an assembling method. The assembling method at least comprises the following steps that the single-piece assembly is assembled; a shaping single-piece assembly is additionally welded; mounting a single-piece assembly; mounting the mounting hard points; mounting a frame; and demolding. According to the automobile assembly chassis provided by the invention, the relative precision of mounting hard points between different single-piece assemblies can be effectively improved, so that the possibility of abnormal problems such as chassis abnormal sound, braking deviation and tire abrasion in the running process of an automobile can be effectively prevented, and maintenance can be reduced to a certain extent.
