The invention relates to a novel aluminum full-frame type rear auxiliary frame. The frame comprises a left longitudinal beam, a right longitudinal beam, a front cross beam, a middle cross beam and a rear cross beam, and the left longitudinal beam, the front cross beam, the right longitudinal beam and the rear cross beam are sequentially connected to form a rectangular frame structure. The middle cross beam is arranged between the front cross beam and the rear cross beam; left and right ends of the middle cross beam are respectively connected with the left and right longitudinal beams; and a left front sleeve and a left rear sleeve are welded to the front end and the rear end of the left longitudinal beam correspondingly. A right front sleeve and a right rear sleeve are welded to the frontend and the rear end of the right longitudinal beam respectively, a front suspension support is welded to the front cross beam, a left rear suspension support and a right rear suspension support are welded to the left side and the right side of the rear cross beam respectively, the left longitudinal beam and the right longitudinal beam are aluminum castings, and the front cross beam, the middle cross beam and the rear cross beam are aluminum extrusion profiles. According to the aluminum full-frame type rear auxiliary frame, the self mass can be reduced to the maximum extent, the endurance mileage of the whole vehicle is increased, the number of parts is small, the production efficiency is high, and the problems that a traditional rear auxiliary frame is large in number of procedures, highin cost, low in production efficiency and the like are solved.

    本发明涉及一种新型铝制全框式后副车架,包括左纵梁、右纵梁、前横梁、中横梁、后横梁,左纵梁、前横梁、右纵梁、后横梁依次连接并构成一矩形框架结构,前横梁与后横梁之间设置有中横梁,中横梁左右两端分别与左纵梁、右纵梁连接,左纵梁的前后端分别焊接有左前套管、左后套管,右纵梁的前后端分别焊接有右前套管、右后套管,前横梁上焊接有前悬置支架,后横梁上左、右两侧分别焊接有左后悬置支架、右后悬置支架,左纵梁、右纵梁均为铝铸件,前横梁、中横梁、后横梁均为铝制挤压型材;本发明能够最大限度地减轻自身质量,增加整车续航里程,且零件少,生产效率高,避免了传统后副车架所存在的工序多、成本较高、生产效率低等问题。
