The invention relates to the technical field of automobiles, in particular to an automobile and an air suspension thereof. The automobile air suspension comprises an automobile frame, an axle and suspension connecting assemblies symmetrically arranged on the two sides of the automobile frame, wherein each suspension connecting assembly comprises a first support, a plate spring, a second support, an air bag and a shock absorber; the first supports are fixedly connected with the automobile frame, the first ends of the plate springs are hinged to the first supports, and the second ends of the plate springs are connected with the axle; therefore, the plate spring does not need to be bent to be connected with an axle, an air bag and a shock absorber in the production process, the machining cost of the plate spring in the production process is reduced, stress concentration points are prevented from being formed at the bent positions, the possibility of breakage caused by bending of the plate spring is reduced, and therefore, the working stability of an automobile is improved. In addition, due to the fact that the plate spring does not need to be bent for connection, the length of the plate spring is reduced, use of plate spring materials is reduced, production cost is reduced, meanwhile, the weight of the plate spring is reduced, and the production cost and the weight of the whole automobile are reduced.

    本发明涉及汽车技术领域,尤其涉及一种汽车及其空气悬架。汽车空气悬架包括车架、车桥和对称布置于车架两侧的悬架连接组件,悬架连接组件包括第一支架、板簧、第二支架、气囊和减震器,第一支架与车架固定连接,板簧的第一端与第一支架铰接,第二端与车桥连接,使得生产的过程中不需要对板簧弯折后连接车桥、气囊和减震器,降低了生产时板簧的加工费用,避免在折弯处形成应力集中点,降低了板簧弯折造成断裂的可能性,从而增加了汽车的工作稳定性。另外,由于无需弯折板簧进行连接,降低了板簧的长度,从而减少了板簧材料的使用,降低生产成本的同时,降低了板簧的重量,从而降低了汽车整车的生产成本和整车重量。
