The invention belongs to the technical field of automobiles, and particularly relates to a light-weight forged aluminum alloy rear suspension arm assembly for a new energy automobile, which comprises a mounting block, swing arms are symmetrically arranged on two sides of the mounting block, first waist grooves are formed in the tops of the swing arms in a penetrating manner and are used for reducing the mass of the swing arms, and a plurality of reinforcing ribs are arranged in the first waist grooves and are used for reinforcing the swing arms. Every two adjacent reinforcing ribs are arranged in the corresponding first waist groove in a triangular mode and used for improving the strength of the swing arm. A supporting rod is fixed to the position, close to the end, between the outer walls of the two swing arms, two second waist grooves are formed in the top of the supporting rod in a penetrating mode, and a connecting rod fixed to the supporting rod is fixed to one sides of the two swing arms. The manufacturing process and the manufacturing cost can be effectively reduced, stress points can be more uniformly distributed through the symmetrical structure, so that the risk that the swing arm is damaged due to uneven stress is reduced, the longitudinal and transverse tensile strength of the rocker arm body is also improved, the mechanical strength of the device is integrally enhanced, and the service life is prolonged.

    本发明属于汽车技术领域,具体涉及一种轻量化新能源汽车用锻造铝合金后悬架臂总成,包括安装块,所述安装块的两侧对称设置有摆臂,所述摆臂的顶部贯通开设有第一腰槽,用于减轻摆臂的质量,所述第一腰槽的内部设置有多个加强筋,相邻两个所述加强筋呈三角形设置在第一腰槽内,用于增加摆臂的强度;两个所述摆臂的外壁之间且靠近端部位置固定有支撑杆,所述支撑杆的顶部贯通开设有两个第二腰槽,两个所述摆臂的一侧固定有与支撑杆固定的连接杆;本发明能够能有效降低制作工艺和制作成本,对称结构能够更均匀地分布受力点,从而降低摆臂因受力不均而损坏的风险,也增加了摇臂本体纵向和横向的抗拉伸强度,进而整体增强了本装置的机械强度,增加使用寿命。
