The invention relates to the technical field of paddy field tractors, and discloses a drive axle assembly which comprises a drive axle body and a mounting shell, a drive shaft and a transmission shaft are mounted in the drive axle body, a bevel gear is arranged between the drive shaft and the transmission shaft, and a first hydraulic cylinder is mounted on the outer wall of the mounting shell. According to the drive axle assembly and the paddy field tractor with the drive axle assembly, when a tractor drive wheel is maintained, the power of a drive shaft can be externally connected through a transmitting shaft, a piston rod in a reverser is pushed to move, the first hydraulic cylinder, a second hydraulic cylinder and a third hydraulic cylinder are pushed to stretch one by one, and the drive axle and a machine body are lifted; a lifting tool such as a jack is prevented from being additionally carried when the paddy field tractor is lifted, the internal space of the machine is prevented from being occupied, meanwhile, the use convenience is improved, a user does not need to lie down to the bottom of the tractor to install the external jack, certain danger is reduced, and the safety is improved.

    本发明涉及水田拖拉机技术领域,且公开了一种驱动桥总成,包括:驱动桥本体和安装壳,所述驱动桥本体的内部分别安装有驱动轴和传动轴,所述驱动轴和传动轴之间设置有锥齿轮,所述安装壳的外壁安装有第一液压缸。该驱动桥总成及其水田拖拉机,能够便于对拖拉机驱动轮进行维修时,利用传输轴将驱动轴的动力外接,推动换向器内部的活塞杆运动,推动第一液压缸、第二液压缸和第三液压缸逐个伸展,实现对驱动桥和机器本体进行抬升,避免了水田拖拉机在进行抬升时另外携带千斤顶等抬升工具,避免了机械内部的空间被占用,同时提高了使用时的便利性,不必趴入车底对外接千斤顶进行安装,降低了一定的危险性,提高了安全性。
