The invention provides a hinged tractor steering drive axle which is characterized in that a main speed reducer is arranged in the middle of the drive axle, a main pin, a half shaft sleeve and a hub are sequentially arranged on the two sides of the main speed reducer in a rotating mode, a universal joint and a shell penetrate through the interior of the main pin from inside to outside, and an outer half shaft penetrates through the interior of the half shaft sleeve; the two ends of the outer half shaft are rotationally connected with the hub and the universal joint respectively, a limiting mechanism capable of limiting the outer half shaft through steering of the drive axle is arranged in the half shaft sleeve, a transmission mechanism capable of automatically adding lubricating oil through friction force is arranged in the shell, and meanwhile the air bag drives the push rod and the clamping ring to move towards the outer side of the outer half shaft. The sliding frame in the clamping ring is extruded by the outer half shaft, the sliding frame slides towards the sleeve, the two sides of the sliding frame drive the rotating shaft to swing, the rotating shaft can drive the suction cups to be adsorbed to the outer side of the outer half shaft through the swing arms, and then the drive axle can rapidly limit the outer side of the outer half shaft after the outer half shaft turns. And the condition that the outer half shaft shifts after steering is avoided.

    本发明提供一种铰接式拖拉机转向驱动桥,该驱动桥的中间有主减速器,主减速器的两侧依次旋转有主销、半轴套管和轮毂,而主销的内部从内至外贯穿有万向节和壳体,半轴套管的内部贯穿有外半轴,外半轴两端分别与轮毂和万向节旋转连接,半轴套筒的内部设有可利用驱动桥的转向对外半轴形成限位的限位机构,而壳体的内部设有可利用摩擦力自动添加润滑油的传动机构,同时气囊带动推杆和卡环向外半轴的外侧移动,卡环内部的滑动架受到外半轴的挤压,滑动架向套筒的滑动,滑动架的两侧带动转轴摆动,转轴能够通过摆臂带动吸盘与外半轴的外侧吸附,进而使得该种驱动桥能够在外半轴转向后,快速对外半轴的外侧形成限位,避免外半轴在转向后移位的情况。
