The five-connecting-rod rear auxiliary frame comprises a front cross beam (1), a rear cross beam (2) and two side longitudinal beams (3) which are connected between the front cross beam (1) and the rear cross beam (2) and are in bilateral symmetry, the interiors of the front cross beam (1), the rear cross beam (2) and the two side longitudinal beams (3) are hollow, and the front cross beam (1), the rear cross beam (2) and the two side longitudinal beams (3) are communicated with one another to form an integral hollow structure; each side longitudinal beam (3) is of a frame type structure; the rear cross beam (2) comprises a first rear cross beam part (21) and a second rear cross beam part (22), the first rear cross beam part (21) is basically arranged in the horizontal direction, the first rear cross beam part (21) and the second rear cross beam part (22) are basically arranged in the vertical direction, and the first rear cross beam part (21) and the second rear cross beam part (22) are connected together, so that the side face of the rear cross beam (2) is in an L shape. According to the structural design of the five-connecting-rod rear auxiliary frame, the strength, the rigidity, the torque mode and the bending mode of installation points of all spare parts of a suspension system are improved, the wall thickness is uniform, and the weight is light.

    一种五连杆后副车架及车辆,包括前横梁(1)、后横梁(2)以及连接在前横梁(1)和后横梁(2)之间的左右对称的两个侧纵梁(3),前横梁(1)、后横梁(2)以及两个侧纵梁(3)的内部均为中空的,且相互连通形成整体式中空结构;各侧纵梁(3)均为框式结构;后横梁(2)包括第一后横梁部(21)和第二后横梁部(22),第一后横梁部(21)基本上沿水平方向设置,与第二后横梁部(22)基本上沿坚直方向设置且与第一后横梁部(21)连接在一起,从而使后横梁(2)的侧面形成为L形。该五连杆后副车架的结构设计对悬架系统各散件的安装点强度、刚度、扭矩模态、弯曲模态都有提升,且壁厚均匀,重量轻。
