    • An air suspension system of a tandem axle assembly for a trailer includes a front axle air spring configured to be coupled to a front axle assembly of the tandem axle assembly and a rear axle air spring configured to be coupled to a rear axle assembly of the tandem axle assembly. The air suspension system further includes an air reservoir in fluid communication with the front axle air spring and the rear axle air spring and a ratio valve in fluid communication with the air reservoir, the front axle air spring, and the rear axle air spring. The ratio valve is positioned between the air reservoir and the front axle air spring. Further, the ratio valve is selectively operable to send a lesser amount of air from the air reservoir to the front axle air spring than to the rear axle air spring.
    • 用于拖车的串联轴组件的空气悬架系统包括前轴空气弹簧,其构造成联接到串联轴组件的前轴组件和后轴空气弹簧,后轴空气弹簧被配置为联接到串联的后桥组件 轴组件。 空气悬架系统还包括与前轴空气弹簧和后轴空气弹簧流体连通的空气储存器和与储气器,前轴空气弹簧和后轴空气弹簧流体连通的比例阀。 比例阀位于储气器和前轴空气弹簧之间。 此外,比例阀可选择性地可操作以从空气存储器向前轴空气弹簧发送较少量的空气,而不是后轴空气弹簧。
