The invention discloses an air spring and metal spring combined type automobile suspension system. The air spring and metal spring combined type automobile suspension system is characterized in that ametal spring is spiral, the air spring is arranged in the middle of the metal spring in a penetrating mode, the air spring comprises an upper base, an air bag body and a lower base, and the upper base and the lower base are inserted into the two ends of the air bag body respectively and connected in a sealed mode; a sealed space is formed by the air bag body, and the air bag body can axially stretch. The combination of the metal spring and the air spring is adopted, and the air spring is arranged in the middle of the metal spring in a penetrating manner, so that the original structure of thesuspension system is not influenced; when the height and the elastic damping of the automobile body are adjusted, only the air pressure in the air bag body needs to be adjusted, in addition, when theair spring breaks down, the use of the suspension system cannot be influenced through the metal spring, and finally, the safety and the comfort of the automobile in the running process can be improvedthrough the combination of the air spring and the metal spring.

    本发明公开了一种空气弹簧和金属弹簧结合式汽车悬挂系统,金属弹簧为螺旋状,空气弹簧穿设在金属弹簧的中部,空气弹簧包括上底座、气囊本体和下底座,所述上底座、下底座分别插入到气囊本体的两端,并密封连接,使气囊本体形成密封空间,气囊本体可轴向伸缩。本发明采用金属弹簧与空气弹簧的结合,并将空气弹簧穿设在金属弹簧的中部,使其不会对悬挂系统的原有结构造成影响;在对车身的高度及弹性阻尼进行调节时,只需对气囊本体内的气压进行调节即可,另外,当空气弹簧出现故障时,通过金属弹簧仍不会影响悬挂系统的使用,最终,通过空气弹簧和金属弹簧的结合,可提高汽车在行驶时的安全性和舒适性。
