The invention discloses an auxiliary frame and an automobile. The auxiliary frame comprises a first front cross beam, a second front cross beam, a first rear cross beam, a second rear cross beam, a left longitudinal beam and a right longitudinal beam; the first end of the first front cross beam is fixedly connected with the first end of the left longitudinal beam, and the second end of the first front cross beam is fixedly connected with the first end of the right longitudinal beam; the first end of the first rear cross beam is fixedly connected with the second end of the left longitudinal beam, and the second end of the first rear cross beam is fixedly connected with the second end of the right longitudinal beam. The two ends of the second front cross beam are fixedly connected with the sides, close to the first front cross beam, of the left longitudinal beam and the right longitudinal beam; the two ends of the second rear cross beam are fixedly connected with the sides, close to the first rear cross beam, of the left longitudinal beam and the right longitudinal beam respectively. According to the auxiliary frame, the two front cross beams and the two rear cross beams are arranged, so that the strength and the rigidity of the auxiliary frame are guaranteed. The auxiliary frame is formed in a welding mode, the cost is greatly reduced, and when a production line needs to produce an auxiliary frame of a new vehicle type, the sizes of the longitudinal beams and the cross beams can be adjusted so as to adapt to production of auxiliary frames of different sizes.

    本申请公开了一种副车架及汽车,其中前者包括第一前横梁、第二前横梁、第一后横梁、第二后横梁、左纵梁和右纵梁,第一前横梁的第一端与左纵梁的第一端固定连接,第一前横梁的第二端与右纵梁的第一端固定连接;第一后横梁的第一端与左纵梁的第二端固定连接,第一后横梁的第二端与右纵梁的第二端固定连接。第二前横梁的两端分别与左纵梁和右纵梁靠近第一前横梁一侧固定连接;第二后横梁的两端分别与左纵梁和右纵梁靠近第一后横梁一侧固定连接。本申请的副车架,前、后横梁均有两根,使得副车架强度和刚度得到保证。副车架焊接成型,成本大为降低,且当产线需要生产新的车型的副车架时,可以调整纵梁和横梁的尺寸,以适应不同尺寸的副车架的生产。
