The invention discloses a three-axle semitrailer with a variable axle load. A support assembly is included. The support assembly comprises a front support assembly, two middle support assemblies and arear support assembly. The two middle support assemblies are located in the middle of the front support assembly and the middle of the rear support assembly respectively. Three plate spring components are arranged among the front support assembly, two middle support assemblies and the rear support assembly; and a shaft fixing connecting piece is arranged in the middle of the plate spring assembly. According to the three-axle semitrailer with the variable axle load, a relative position of a suspension fulcrum is changed so that the load of one axle shaft is reduced; therefore, tires of rear wheels of the semitrailer are reduced, whole vehicle weight is decreased, and a whole vehicle cost is reduced; and in addition, a friction area between the tires and the ground is decreased, an effect of saving fuel oil is achieved, tail gas emission of the vehicle is reduced, one axle shaft of the three axle shafts is changed into a light axle shaft, the production cost of the axle is further reduced, the weight of the axle is decreased, and the effects of energy conservation and environmental protection are also achieved.

    本发明公开了一种可变轴荷的三轴半挂车,包括支架组件,支架组件包括前支架总成、两个中支架总成和后支架总成,两个中支架总成分别位于前支架总成和后支架总成的中间位置,前支架总成、两个中支架总成和后支架总成之间设有三个板簧组件,板簧组件的中间设有轴固定连接件,本可变轴荷的三轴半挂车,通过过改变悬架支点相对位置,使其中一个桥轴的载荷变小,以此将半挂车后轮轮胎减少,降低了整车重量,降低整车成本的作用,另外轮胎与地面的摩擦面积减少,起到节省燃油的作用,减少车辆的尾气排放,三个桥轴的其中一个桥轴变为轻型桥轴,进一步降低了生产车桥的成本,降低了车桥的重量,也起到了节能环保的作用。
