The invention relates to the technical field of rear axles, in particular to a heightened and widened rear axle of a medium-high horsepower section tractor, which comprises a spindle box and two groups of in-box partition plates arranged in the spindle box, an inner fixing seat is formed in the spindle box, and a rotating speed adapter for rotating speed matching is arranged in the inner fixing seat. A power input assembly is arranged in the middle of the spindle box, the power input assembly is connected with a rotating speed adapter and provides rotating power for the rotating speed adapter, a linkage gear enables a transmission sleeve to rotate synchronously in the rotating process, and in the synchronous rotating process of the transmission sleeve, a planetary gear rod in the transmission sleeve drives a planetary gear to rotate synchronously along with the transmission sleeve. The rotation of the power transmission rod reversely acts on the transmission gear, when the rotation speed of the power transmission rod is reduced, the rotation speed of the transmission gear connected with the power transmission rod is synchronously reduced, at the moment, the planetary gear rotates relative to the transmission gear, power transmission is reduced, matching of the rotation speed is completed, and therefore tire abrasion under the large-torsion working condition is reduced.

    本发明涉及后桥技术领域,具体涉及一种中大马力段拖拉机加高加宽的后桥,包括主轴箱、以及设置于主轴箱内部的两组箱内隔板,所述主轴箱的内部成型有内固定座,所述内固定座的内部设置有用于转速匹配的转速适配器,所述主轴箱中部设置有动力输入组件,所述动力输入组件与转速适配器连接,为转速适配器提供转动动力,联动齿轮在转动过程使传动套同步转动,传动套在同步转动过程中,传动套内部的行星齿轮杆带动行星齿轮随传动套同步转动,动力输送杆的旋转反向作用于传动齿轮,动力输送杆转速降低时,与之连接的传动齿轮的转速同步降低,此时行星齿轮相对传动齿轮旋转,减少动力传输,完成转速的匹配,从而减少在大扭力的作业工况下的轮胎磨损。
