The invention relates to a drive axle assembly. The drive axle assembly comprises an axle housing, a speed reducer unit, a half shaft unit and a conversion mechanism, the speed reducer unit, the half shaft unit and the conversion mechanism are mounted on the axle housing, the speed reducer unit comprises an input structure, a transmission assembly and a first conversion assembly, the input structure is configured as a power input end, and the first conversion assembly is used for connecting or separating the transmission assembly and the input structure; the half shaft unit comprises a first output shaft and a second output shaft, one end of the first output shaft is connected with one hub, and one end of the second output shaft is connected with the other hub; the conversion mechanism comprises a second conversion assembly and a third conversion assembly, the second conversion assembly is used for connecting or separating the other end of the first output shaft with or from the transmission assembly, and the third conversion assembly is used for connecting or separating the other end of the second output shaft with or from the transmission assembly. By means of the arrangement, switching between the 6 * 4 driving mode and the 6 * 2 driving mode of the tractor is achieved, and when the tractor is in a no-load state or in a non-full-load state, the 6 * 2 driving mode can improve transmission efficiency and reduce fuel consumption.

    本申请涉及一种驱动桥总成。驱动桥总成包括桥壳及安装于桥壳的减速器单元、半轴单元及转换机构,减速器单元包括输入结构、传动组件及第一转换组件,输入结构配置为动力输入端,第一转换组件用于将传动组件与输入结构连接或分离;半轴单元包括第一输出轴与第二输出轴,第一输出轴的一端与一个轮毂相连,第二输出轴的一端与另一轮毂相连;转换机构包括第二转换组件及第三转换组件,第二转换组件用于将第一输出轴的另一端与传动组件连接或分离,第三转换组件用于将第二输出轴的另一端与传动组件连接或分离。通过上述设置,实现了牵引车在6x4的驱动模式与6x2的驱动模式之间的切换,当车辆空载或非满载时,6x2的驱动模式会提高传动效率,减少燃油消耗。
