摘　　要：介绍商用车空气悬架的发展历史、结构和优势,以及国内外空气悬架轻量化的发展现状。对空气悬架中的前支架、导向臂和空气弹簧结构的轻量化进行详细论述:在材料方面,利用复合材料和高强度合金材料所生产的部件替代现有的部件,有效减轻了部件质量;在结构方面,运用拓扑优化方法,对现有的结构进行优化设计,取得了较好的轻量化效果。The development history,structure and advantages of air suspension of commercial vehicles are introduced,as well as the domestic and foreign development status of lightweight air suspension.The lightweight of the front bracket,guide arm and air spring structure in air suspension are discussed in detail.In terms of materials,the components made of composite materials and high-strength alloy materials are used to replace the existing components,which effectively reduces the mass of components.In terms of structure,the topology optimization method is used to optimize the design of the existing structure,and a good lightweight effect is achieved.
