A spring insert mounting structure comprises a base, a supporting frame, a rocker arm, rubber, a spiral spring and a pressing rod. The pressing rod is composed of a pressing rod body and a pressing disc fixedly connected with the lower end of the pressing rod body. The lower end of the supporting frame is fixedly connected with the left end of the base, the left end of the rocker arm is in rollingconnection with the upper end of the supporting frame, a through hole connected with an engine is formed in the right end of the rocker arm, and the upper end of the pressing rod body and the right end of the rocker arm are fixedly connected to the left of the through hole. The lower end of the rubber is fixedly connected with the base, the upper end of the rubber is located below the pressing disc, the spiral spring is coaxial with the rubber, the outer diameter of the rubber is matched with the inner diameter of the spiral spring, the diameter of the pressing disc is smaller than the innerdiameter of the spiral spring, the upper end of the spiral spring is connected with the right end of the rocker arm, and the lower end of the spiral spring is connected with the base. All the parts are simple in structure and easy to machine, manufacture and assemble, a spring, a rubber main spring and the pressing rod are combined in the main direction, and the NVH can be improved by changing thethree-way proportion of a mount to facilitate decoupling of a mounting system.
弹簧镶块悬置结构,包括底座、支撑架、摇臂、橡胶、螺旋弹簧、压杆。所述压杆由压杆本体和与压杆本体下端固定相连的压盘构成。支撑架的下端和底座的左端固定相连,摇臂的左端和支撑架的上端滚动相连,摇臂的右端设有用于和发动机相连的通孔,压杆本体的上端和摇臂的右端固连于通孔的左边。橡胶的下端和底座固连,橡胶的上端位于压盘的下方,螺旋弹簧和橡胶同轴,橡胶的外径和螺旋弹簧的内径适配,压盘的直径小于螺旋弹簧的内径,螺旋弹簧的上端和摇臂的右端相连,螺旋弹簧的下端和底座的右端相连。本发明各部分的结构简单,加工制作和装配容易,主方向采用弹簧、橡胶主簧和压杆结合配置,可通过改变悬置三向比例以方便悬置系统解耦来提高NVH。
