The tractor gearbox capable of achieving pivot steering comprises a box body, an HST and a gear set are arranged at the front end of the box body, the gear set is arranged in the box body, connected with the HST and used for power transmission, and the gear set comprises a front driving set, a rear driving set, a reverse rotation control set, a right half shaft set and a left half shaft set; a power input shaft is arranged at the front end of the HST, the HST transmits power to the rear drive set and the front drive set, the rear drive set transmits power to the left half shaft set and the right half shaft set, and the reverse rotation control set controls the left half shaft set and the right half shaft set to rotate reversely. Therefore, small-turning steering and even in-situ steering can be achieved, stepless speed regulation of the steering speed of the tractor is achieved, the requirement for machine tool operation is met, forward rotation and reverse rotation of the left wheel and the right wheel are achieved, many manual operation steps are omitted, and the working efficiency is greatly improved.

    本发明提供了一种可实现原地转向的拖拉机变速箱,包括箱体,所述箱体的前端设有HST和设于所述箱体内部的与所述HST连接的用于动力传输的齿轮组,所述齿轮组包括前驱动组、后驱动组、反转控制组、右半轴组和左半轴组;所述HST的前端设有动力输入轴,所述HST将动力传递给所述后驱动组和前驱动组,所述后驱动组将动力传递给所述左半轴组和所述右半轴组,所述反转控制组控制所述左半轴组和右半轴组反向转动。借此,本发明能够实现小拐弯转向,甚至实现原地转向,拖拉机转向速度实现无级调速,适应了机具作业的需要,实现了左右轮一正一反转动,省掉许多人工操作步骤,极大提高工作效率。
