A linkage steering system with a front axle deflecting along with front wheels comprises a steering axle, a front bracket, a steering axle mounting hinge frame, a linkage rod, a middle steering oil cylinder, a front wheel hub, a transfer case and a steering axle transition connecting frame. The power output end of the transfer case transmits power to the steering axle through the transmission unit, the steering axle is installed on the lower side face of the front bracket and fixedly connected with the steering axle transition connecting frame, and the steering axle transition connecting frame is installed on the steering axle installation hinge frame through an upper pin shaft and a lower pin shaft which are installed on the upper plane and the lower plane of the hinge frame. The steering axle installation hinge frame is of a box-shaped structure and is fixedly connected to the two sides of the front bracket through locking pieces. One end of the linkage rod is hinged to the main pin upper end cover of the front wheel hub, and the other end is hinged to the front bracket; the middle steering oil cylinder is located at the front end of the steering axle and connected with front wheel hubs on the two sides through spherical hinges. According to the scheme, through structural optimization, the deflection angle of the front wheels is increased, and the steering radius of the tractor is further reduced.
一种前桥跟随前轮偏转的联动转向系统,包括转向桥、前托架、转向桥安装铰接架、联动杆、中置转向油缸、前轮轮毂、分动箱以及转向桥过渡连接架;分动箱的动力输出端通过传动单元将动力传递至转向桥,所述转向桥安装在前托架的下侧面并与转向桥过渡连接架固定连接,转向桥过渡连接架通过安装在铰接架上下平面的上销轴以及下销轴安装在转向桥安装铰接架上,所述转向桥安装铰接架为箱型结构,并通过锁紧件固定连接在前托架两侧;联动杆一端铰接在前轮轮毂的主销上端盖上,另一端铰接在前托架上;所述中置转向油缸位于转向桥前端,通过球铰连接两侧前轮轮毂。本方案通过结构优化,加大了前轮的偏转角度,进一步减小拖拉机的转向半径。
