The invention relates to the technical field of tractor control mechanisms, and particularly relates to a crawler tractor walking and steering linkage control mechanism which comprises a rotating shaft arm, a steering gear box, a steering cam and a sleeve. Two ends of the rotating shaft arm are connected with a left control steering arm and a right control steering arm through a pull rod assemblyand a rocker arm assembly respectively; the rotating shaft arm is installed on the steering gear box, the steering gear box is installed on a sliding rail in a sliding mode, and a chassis base of thesteering gear box is connected with a control lever through a fifth pull rod; the steering cam is connected with the direction rotating arm and can drive the direction rotating arm to rotate; and thesleeve is connected with a steering wheel, and a sliding shaft is installed in the sleeve in a sliding mode. In the invention, walking forward, backward and steering of the crawler tractor can be directly controlled, operation is simple and convenient, a walking speed of the crawler tractor can be steplessly adjusted by linking the left control steering arm and the right control steering arm of aduplex pump, and in-situ differential steering and zero turning of the tractor can be realized.
本发明涉及拖拉机操纵机构技术领域,特别涉及一种履带拖拉机行走转向联动操纵机构,包括转轴臂、方向机、转向凸轮和套筒,所述转轴臂两端分别通过拉杆组件以及摇臂组件与控左转向臂和控右转向臂相连;所述转轴臂安装于方向机上,所述方向机滑动安装于滑轨上,所述方向机的底盘座通过第五拉杆与操纵杆相连;所述转向凸轮与方向转臂相连并可带动方向转臂转动;所述套筒与方向盘相连且所述套筒内滑动安装有滑动轴。本发明可以直接控制履带拖拉机行走的前进后退及转向,操作简单方便,通过联动双联泵的控左转向臂以及控右转向臂使履带拖拉机行走速度无级可调,并可实现拖拉机原地差速转向,零转弯。
