The lower swing arm assembly comprises a lower swing arm, the front end of the inner side of the lower swing arm is provided with a first connecting part, the rear end of the inner side of the lower swing arm is provided with a second connecting part, the first connecting part and the second connecting part are connected with a longitudinal beam of a front auxiliary frame, and the outer side of the lower swing arm is provided with a third connecting part; the connecting support is connected to the third connecting part, and the connecting support is used for being connected with a steering knuckle; at least part, close to the third connecting part, of the outer side of the lower swing arm is configured to be a fracture area, and the fracture area is suitable for being fractured during collision and enabling the connecting support to be separated relative to the lower swing arm. According to the lower swing arm assembly, at least part of the outer side of the lower swing arm is configured to be the fracture area, so that after the vehicle is collided, the fracture area is effectively fractured, the connecting support is separated relative to the lower swing arm to be thrown outwards, the risk of passengers caused by backward movement of wheels can be prevented, and the collision performance of the vehicle is improved; and the safety of passengers in the offset collision process is improved.

    本发明公开了一种下摆臂总成和车辆,下摆臂总成包括:下摆臂,下摆臂的内侧前端设有第一连接部且内侧后端设有第二连接部,第一连接部和第二连接部分别与前副车架的纵梁相连,下摆臂的外侧设有第三连接部;连接支架,连接支架连接于第三连接部,连接支架用于与转向节相连;其中,下摆臂的外侧靠近第三连接部的至少部分构造为断裂区域,断裂区域适于在碰撞时断裂且使连接支架相对于下摆臂脱离。本发明的下摆臂总成,通过设置下摆臂的外侧至少部分构造为断裂区域,可使车辆受到碰撞后,断裂区域有效断裂,连接支架相对于下摆臂脱离以朝向外侧甩出,可以防止车轮向后运动对乘员造成风险,提升了车辆的碰撞性能,且提升偏置碰撞过程中的乘员安全性。
