The invention discloses a tractor four-wheel steering mechanism and a control method thereof. The steering mechanism comprises a steering gear, and a front steering longitudinal pull rod, a rear steering longitudinal pull rod, a front steering transverse pull rod, a rear steering transverse pull rod, a front steering knuckle arm and a rear steering knuckle arm in control connection with the steering gear. The steering gear is a gear box and comprises a driving steering shaft, two driving steering gears, two driven steering shafts and seven driven steering gears, and the steering shifting forkslides left and right to be connected with the driving steering gears. The mechanism is simple in structure, convenient to operate and low in use and maintenance cost. The tractor can realize same-direction deflection and different-direction deflection of the front wheel and the rear wheel according to actual working requirements, the turning radius is reduced, the steering sensitivity and the driving stability are improved, and the requirements of different working conditions can be met. According to the control method, different-direction steering or same-direction steering is selected according to the speed, the turning radius is effectively reduced or the steering sensitivity is improved, and the running stability of the tractor is improved.
本发明公开了一种拖拉机四轮转向机构及其控制方法,其转向机构包括转向器,由转向器连接控制的前转向纵拉杆、后转向纵拉杆、前转向横拉杆、后转向横拉杆,前转向节臂、后转向节臂;转向器是一个齿轮箱,包括一个主动转向轴、两个主动转向齿轮、两个从动转向轴和七个从动转向齿轮,转向拨叉左右滑动与主动转向齿轮连接。该机构结构简单,操作方便,使用维护成本低。本发明可以使拖拉机根据实际工作需要实现前后轮同向偏转和异向偏转,降低了转弯半径,提高了转向灵敏度和行驶稳定性,并且能满足不同工作状况的需求。其控制方法根据速度选择异向转向或同向转向,有效减小转弯半径或提高转向灵敏度提高拖拉机的行驶稳定性。
