The invention provides an integrated maintenance-free axle air suspension which comprises an integrated axle, an air bag, a shock absorber and a suspension lifting lug, the integrated axle comprises an axle body, an air bag bottom support, a shock absorber lower support boss and a guide arm, the air bag bottom support, the shock absorber lower support boss and the guide arm are integrally formed with the axle body, and the air bag is arranged on the air bag bottom support. According to the invention, the guide arm and the air bag bottom support are not connected with the axle by adopting a bolt tightening or welding process, so that vehicle accidents caused by bolt loosening and bolt breakage are avoided, the defect of open welding of the welding process is also avoided, and the air bag bottom support is free of maintenance all the time; the weight is light, the structure is simple, faults are few, the service life is long, and safety and reliability are further improved.
本发明提出了一种整体式免维护车轴空气悬架,包括一体式车轴、气囊、减震器、悬架吊耳,一体式车轴包括车轴本体,及与车轴本体一体成型的气囊底托、减震器下支架凸台、导向臂,气囊安设于气囊底托上,减震器底端与减震器下支架凸台相连接,悬架吊耳与导向臂相连接,本发明取消导向臂和气囊底托采用螺栓拧紧或焊接工艺与车轴连接,避免螺栓松动、螺栓断裂造成车辆事故,也避免焊接工艺开焊弊病,终身免维护,重量轻、结构简单、故障少、寿命长、安全可靠性也进一步提高。
