The invention discloses a double-flow drive steering drive axle which is mainly formed by combining a hydraulic drive steering assembly, a left reduction assembly, a right reduction assembly and a central speed reduction assembly, and two paths of power flow input drive, one path of mechanical transmission and one path of hydraulic power source transmission are achieved through the hydraulic drive steering assembly and the central speed reduction assembly. Convergence is achieved on driving driven wheels of the left reduction assembly and the right reduction assembly, and the main functions of whole machine driving, pivot steering driving, braking control and the like of the tractor are achieved. Conventional power comes from the central speed reduction assembly, and steering power comes from the hydraulic drive steering assembly. Wherein hydraulic transmission is adopted for steering, an idle wheel is additionally arranged, so that the steering directions of a left driving driven gear and a right driving driven gear are opposite, the overall operation is convenient, rapid and labor-saving, in-situ steering can be achieved, the turning radius is minimum, mechanical transmission is adopted for walking and working PTO, and the transmission efficiency is high.

    本发明公开了一种双流驱动的转向驱动桥,主要由液压驱动转向总成、左边减总成、右边减总成、中央减速总成组合而成,通过液压驱动转向总成、中央减速总成两路功率流输入驱动,一路机械传动,一路液压动力源传动,在左、右边减总成的驱动从动轮上汇流,实现拖拉机的整机驱动、原地转向驱动以及制动控制等主要功能。常规动力来自中央减速总成,转向动力来自液压驱动转向总成。其中转向采用液压传动,通过增设惰轮,使得左驱动从动齿轮和右驱动从动齿轮转向相反,整体操作方便快捷、省力,可实现原地转向,转弯半径最小,行走及工作的PTO采用机械传动,传动效率高。
