The invention belongs to the technical field of auxiliary frames, and provides a new energy automobile lightweight collision energy absorption aluminum alloy auxiliary frame which comprises a left longitudinal beam, a right longitudinal beam, a middle cross beam, a front cross beam, a rear cross beam, a left front mounting bracket, a right front mounting bracket, a left rear mounting bracket and a right rear mounting bracket. The front cross beam, the middle cross beam, the left longitudinal beam and the right longitudinal beam are connected together in a butt welding mode, and the left front installation support is connected to the left longitudinal beam. The method has the advantages that through the ingenious design of sections in various shapes, half shaft enveloping is effectively avoided; the advantage of collision energy absorption of extruded profiles is fully exerted, the manufacturability is high, the problems of breakage, insufficient energy absorption and low yield of a fully-cast aluminum auxiliary frame after collision and bending are solved, the overall collision requirement of the auxiliary frame is met, and the safety is high; the aluminum profile is high in yield and high in production efficiency, the production cost is reduced, the middle installation support is selectively installed, different configurations are adapted, and the tool cost is reduced.
本发明属于副车架技术领域,提供了一种新能源汽车轻量化碰撞吸能铝合金副车架,包括左纵梁、右纵梁、中间横梁、前横梁以、后横梁、左前安装支架、右前安装支架,左后安装支架以及右后安装支架,前横梁、中间横梁与左纵梁和右纵梁通过对接焊接连接在一起,左前安装支架连接在左纵梁上。本发明的优点在于通过各种形状截面的巧妙设计,有效的避让了半轴包络;充分发挥挤压型材碰撞吸能的优点,可制造性强,解决全铸造铝副车架碰撞折弯后断裂,吸能不足及成品率低的问题,满足副车架整车碰撞要求,安全性高;利用铝型材良品率高,生产效率高,降低了生产成本,选装中间安装支架,适配不同配置,减少工装成本。
