The invention belongs to the technical field of vehicle suspension structures and particularly discloses a combined type air suspension system and an automobile. The combined type air suspension system comprises a vehicle frame, a spring suspension and an axle, wherein the spring suspension comprises a steel plate spring, an air spring, a shock absorber, a front support, a lifting lug and a rear support, two ends of the steel plate spring are connected with the vehicle frame through the front support, the lifting lug and the rear support respectively, and an axle is arranged on a lower side of the steel plate spring; the air spring is arranged between the steel plate spring and the frame and located behind the center line of the axle so as to reduce the braking longitudinal torsion effect of the steel plate spring; the air spring bears all sprung mass, and the steel plate spring is in a reverse bow state, so deformation of the steel plate spring can be reduced, the working stress of the steel plate spring is obviously reduced, and the fatigue damage of the steel plate spring is relieved, so the service life of the steel plate spring is prolonged.
本发明属于车辆悬架结构技术领域,具体公开了一种复合式空气悬架系统及汽车。其中该复合式空气悬架系统包括车架、弹簧悬架、车桥,弹簧悬架包括钢板弹簧、空气弹簧、减振器、前支座、吊耳,以及后支座,钢板弹簧的两端分别通过前支座、吊耳以及后支座与车架连接,车桥设置于钢板弹簧的下侧,空气弹簧设置在钢板弹簧与车架之间,且空气弹簧位于车桥中心线的后方,以减小钢板弹簧的制动纵扭效应;并且空气弹簧承担全部簧上质量,钢板弹簧处于反弓状态,可减小钢板弹簧的变形量,明显降低钢板弹簧的工作应力,减缓钢板弹簧的疲劳损坏,以延长钢板弹簧的工作寿命。
