The invention particularly relates to an aluminum alloy imbedding auxiliary frame of a passenger car and a manufacturing process of the aluminum alloy imbedding auxiliary frame. The auxiliary frame comprises a left side longitudinal beam, a right side longitudinal beam, a front cross beam and a rear cross beam. The front cross beam and the rear cross beam are arranged in parallel, and the left side longitudinal beam and the right side longitudinal beam are located on the two sides of the front cross beam and the two sides of the rear cross beam respectively and connected with the front cross beam and the rear cross beam in an imbedding mode. The left side longitudinal beam comprises a left side casting and a left aluminum profile, the left side casting and the left aluminum profile are connected through imbedding, the right side longitudinal beam comprises a right side casting and a right aluminum profile, and the right side casting and the right aluminum profile are connected through imbedding; the aluminum profile is embedded in the casting mold in advance and integrally formed through the aluminum alloy high-vacuum die-casting process, and the problems that a steel auxiliary frame is heavy, the welding process of an aluminum alloy low-pressure casting/aluminum profile welding auxiliary frame is complex, and the process difficulty of aluminum alloy overall hollow low-pressure casting auxiliary frame is large are solved.
