The invention discloses a front drive axle with two gears, which relates to the technical field of tractors and comprises a planetary structure fixed on a front axle shell, the planetary structure comprises a gear ring, a planetary carrier is arranged on one side in the gear ring, a planetary gear is rotatably arranged on one side, close to the gear ring, of the outer wall of the planetary carrier, and the planetary gear is meshed with the gear ring. A sun gear is arranged at the axis in the gear ring and meshed with the planetary gear, one side of the planet carrier is rotationally connected with a front axle input shaft, a gear shifting mechanism is arranged on the side, close to the front axle input shaft, of the inner wall of the planet carrier and arranged on the front axle input shaft in a sleeving mode, and a sun gear shifting spline is fixedly connected with the sun gear. Through the arrangement of the gear shifting mechanism, mode switching of two gears can be achieved, different driving conditions and task requirements are better met, meanwhile, the flexibility of a driving system is improved, and two different traction force and driving force are provided for a tractor under special conditions.

    本发明公开了一种两档设置前驱动桥,涉及拖拉机技术领域,包括固定在前桥壳体上的行星结构,行星结构包括齿圈,齿圈内部一侧设置有行星架,行星架外壁靠近齿圈的一侧转动设置有行星齿轮,行星齿轮与齿圈相啮合,齿圈内部轴心处设置有太阳轮,太阳轮与行星齿轮相啮合,行星架一侧转动连接有前桥输入轴,行星架内壁靠近前桥输入轴的一侧设置有换挡机构,且换挡机构套设在前桥输入轴上,太阳轮换挡花键与太阳轮固定连接,行星架花键与行星架固定连接,本发明通过换挡机构的设置,可以实现两个挡位的模式切换,更好的满足不同的行驶条件和任务需求,同时增加了驱动系统的灵活性,为拖拉机在特殊情况下提供两种不同的牵引力和驱动力。
