The invention relates to the technical field of tractor chassis, and discloses a four-wheel-drive-wheel tractor which comprises a fixed rod, fixed ventilation pipes are fixedly installed at the two ends of the fixed rod, transmission rods are movably connected into the fixed ventilation pipes in a sleeved mode, and wheels are fixedly installed on one sides of the bottoms of the transmission rods. According to the four-wheel-drive-wheel tractor, by arranging the fixed connecting box, the movable rod, the inflation bag, the air bag gear ring and other components, the effect of preventing large torque from being generated between the steering knuckle arm and the circulation air cavity is achieved, the steering knuckle arm and the circulation air cavity are stably connected, meanwhile, the situation that the structure is damaged due to the fact that the circulation air cavity is excessively pressed is avoided, and the service life of the tractor is prolonged. By arranging the limiting partition plate, friction heat energy between the steering knuckle arm and the circulating air cavity is cooled in real time, and the problems that excessive friction heat is accumulated between the steering knuckle arm and the circulating air cavity, heat losses of the steering knuckle arm and the circulating air cavity are serious, the service life of the steering knuckle arm and the circulating air cavity are greatly shortened, and time and labor are wasted due to the fact that parts need to be frequently replaced are solved.

    本发明涉及拖拉机底盘技术领域,且公开了一种四驱轮式拖拉机,包括固定杆:所述固定杆的两端固定安装有固定通气管,所述固定通气管的内部活动套接有传动杆,所述传动杆的底部一侧固定安装有车轮。本申请提供的一种四驱轮式拖拉机,通过设置固定连接盒、活动杆、充气囊以及气囊齿环等部件,实现了阻止转向节臂和循环气腔之间产生较大扭矩作用,使转向节臂和循环气腔连接稳固,同时,避免循环气腔受压过大而结构受损,通过设置限位隔板,将转向节臂和循环气腔之间的摩擦热能进行实时降温,避免转向节臂和循环气腔之间积攒过量的摩擦热,而造成转向节臂和循环气腔热损严重,使其使用周期极大缩减,需要频繁更换零件费时费力的效果。
