The invention provides an upper A-shaped arm structure, an upper A-shaped arm assembly, a suspension system and a vehicle, the upper A-shaped arm structure comprises an upper A-shaped arm body integrally formed by forging aluminum alloy, the upper A-shaped arm body comprises two support arms, one ends of the two support arms are connected with each other, and a first preset angle is formed betweenthe two support arms; the ball pin press-fitting holes are formed in the connecting ends of the two supporting arms; the upper A-shaped arm bushing press-fitting holes are formed in the non-connecting ends of the two supporting arms, and the non-connecting ends are opposite to the connecting ends; and the wire harness bracket mounting part is arranged on the support arm. The upper A-shaped arm structure 1 is integrally formed through forging and made of light materials such as aluminum alloy, the number of parts, the number of dies and process steps are reduced, on the basis that the originalfunctions of the upper A-shaped arm structure 1 are guaranteed, the cost is saved, the quality is reduced, the consistency of products is guaranteed, light weight of a vehicle is achieved. Maneuverability of a vehicle is improved.
本发明提供了一种上A字臂结构、上A字臂总成、悬架系统及车辆,其中上A字臂结构,包括:由铝合金锻造一体成型的上A字臂本体,上A字臂本体包括两个一端相互连接的支臂,且两个支臂之间呈第一预设角度设置;开设于两个支臂的连接端的球销压装孔;开设于两个支臂的非连接端的上A字臂衬套压装孔,非连接端与连接端相对设置;以及设置于支臂上的线束支架安装部。本发明的实施例所提供的上A字臂结构1通过锻造一体成型且采用铝合金等轻质材料,减少了零部件数量、模具数量以及工艺步骤,在保证上A字臂结构1原有功能的基础上,节省了成本,降低了质量且保证了产品的一致性,有利于实现车辆轻量化,提高车辆的操控性。
