The invention relates to the technical field of automobile suspensions, and discloses a spring swing arm assembly. The assembly comprises a rod body, an annular plate and a cover plate, a mounting groove used for mounting a spiral spring is formed in the rod body, the annular plate is arranged in the mounting groove, and the outer circumferential side wall of the annular plate is fixedly connected with the inner circumferential side wall of the mounting groove; and the cover plate is provided with a penetrating opening penetrating through the thickness of the cover plate, and the cover plate is fixedly connected to the rod body and enables the penetrating opening to be communicated with the opening of the mounting groove. The annular plate is arranged in the mounting groove, the thickness of the side wall of the mounting groove is increased through the annular plate, so that the overall strength of the rod body is improved, and the requirement for large axial loads is met. In addition, the cover plate is additionally arranged at the opening of the mounting groove, the cover plate can stabilize the opening shape of the mounting groove so as to prevent the mounting groove from deforming, and the loading capacity of the rod body is further improved.

    本发明涉及汽车悬架技术领域,公开了一种弹簧摆臂总成,包括杆体、环形板及盖板,所述杆体上开设有用于安装螺旋弹簧的安装槽,所述环形板设于所述安装槽内,且所述环形板的外周侧壁与所述安装槽的内周侧壁固定连接;所述盖板具有贯穿于其厚度的贯穿口,所述盖板固定连接于所述杆体上并使所述贯穿口与所述安装槽的开口相通。本发明通过在安装槽中设置有环形板,环形板增大安装槽侧壁厚度以增大杆体的整体强度,以满足较大的轴向载荷需求。此外,本发明还在安装槽的开口处增设盖板,盖板能够稳固安装槽开口形状以防止安装槽发生形变,进一步提高杆体的载荷能力。
