The invention discloses a wheel track adjusting mechanism for a tractor, and relates to the technical field of tractors, the wheel track adjusting mechanism comprises supporting beams and a double-end hydraulic cylinder, the supporting beams comprise a first supporting beam and a second supporting beam, a through hole is formed in the middle of the first supporting beam, the second supporting beam penetrates through the through hole, and intersection points of the first supporting beam and the second supporting beam are connected through a rotating shaft; the first supporting beam and the second supporting beam are each internally provided with a cavity, the opposite sides of the first supporting beam and the second supporting beam are each provided with an open groove, the open grooves communicate with the cavities, and the two ends of the double-end hydraulic cylinder are each provided with an output end and extend into the cavities of the first supporting beam and the second supporting beam through the open grooves to be connected with the supporting beams. The whole width of the tractor cannot be increased, the tractor can pass through a narrow road section, the wheels cannot axially slide relative to the wheel shaft, the safety coefficient is high, the wheel distance between the front wheel and the rear wheel can be steplessly adjusted at the same time, and the tractor can work under the wheel distances meeting different operation requirements.

    本发明公开了一种拖拉机用轮距调整机构,涉及拖拉机技术领域,包括支撑梁和双头液压缸,支撑梁包括第一支撑梁和第二支撑梁,第一支撑梁中间开设有通孔,第二支撑梁从通孔内穿过,第一支撑梁和第二支撑梁的交叉点使用转轴连接,第一支撑梁和第二支撑梁内均设有空腔,第一支撑梁和第二支撑梁相对的一侧上均设有开槽,开槽连通空腔,双头液压缸的两端均设有输出端并通过开槽分别伸入第一支撑梁和第二支撑梁的空腔中和支撑梁连接。本发明不会增加拖拉机整体宽度,使拖拉机能够通过较窄路段,不会使车轮相对于轮轴产生轴向滑动,安全系数高,并且能够实现同时无级调整前后轮轮距,使拖拉机可以在不同作业要求的轮距下工作。
