The invention discloses a composite spring vibration reduction device, relates to the technical field of automobile suspension vibration reduction, and solves the problems that an existing air bag and spring composite vibration reduction structure is inconvenient to install and high in cost. A connecting seat; the air bag is limited and fixed between the two limiting structures, the air bag is internally provided with an air chamber, the top of the air chamber is provided with an air inlet stud, the air inlet stud is connected with the upper mounting seat, and the air inlet stud is provided with an air inlet hole communicated with the air chamber; a base; and a spring. When the base is impacted, impact force can be transmitted to the spiral spring, the spiral spring transmits the impact force to the air bag through the connecting seat, the impact force is weakened by the air bag and then transmitted to a vehicle body through the upper mounting seat, the impact force borne by a spiral spring body can be relatively reduced, the service life of the spiral spring is prolonged, the air bag and the spring are combined together, and the service life of the spiral spring is prolonged. The rigidity of the whole suspension device can be reduced, and better comfort is provided.
本发明公开了一种复合弹簧减振装置,涉及汽车悬挂减振技术领域,解决了现有的气囊和弹簧复合减振结构存在安装不便、成本较高的问题,其包括:上安装座;连接座;气囊,所述气囊被限位固定在两个所述限位结构之间,所述气囊内具有气室,所述气室的顶部设置有进气螺柱,所述进气螺柱与所述上安装座连接,所述进气螺柱上具有与所述气室相连通的进气孔;底座;弹簧。本发明中底座受到冲击时会将冲击力传给螺旋弹簧,螺旋弹簧通过连接座,将冲击力传递给气囊,经过气囊的削弱再经由上安装座传递给车身,螺旋弹簧本体受到的冲击力会相对的减小,提高螺旋弹簧的使用寿命,将气囊和弹簧复合在一起,可以降低整个悬架装置的刚度,提供更好的舒适性。
