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.

    本发明具体涉及一种乘用车铝合金镶铸副车架及其制造工艺,所述副车架包括左侧纵梁、右侧纵梁、前横梁和后横梁;所述前横梁和后横梁平行排列,所述左侧纵梁和右侧纵梁分别位于所述前横梁和后横梁两侧,且与所述前横梁和后横梁镶铸连接;所述左侧纵梁包括左侧铸件和左铝型材,所述左侧铸件和左铝型材通过镶铸连接,所述右侧纵梁包括右侧铸件和右铝型材,所述右侧铸件和右铝型材通过镶铸连接;本发明采用铝型材预先镶嵌在铸造模具内并通过铝合金高真空压铸工艺一体成型,解决了钢质副车架重量大、铝合金低压铸件/铝型材焊接副车架焊接工艺复杂、铝合金整体空心低压铸造副车架工艺难度大的问题。
