The invention provides a multifunctional hinged chassis and a tractor, the multifunctional hinged chassis comprises a front frame, a rear frame, a hinged shaft and a telescopic driving mechanism, the front frame and the rear frame are hinged through the hinged shaft, and the hinged shaft is arranged in the height direction; the rear frame comprises a fixed frame and a rotating frame, the fixed frame is hinged to the front frame through a hinge shaft, and the rotating frame is rotationally connected to the fixed frame in the length direction of the rotating frame; the first end of the telescopic driving mechanism is hinged to the front frame, and the second end of the telescopic driving mechanism is hinged to the fixed frame. The telescopic driving mechanism stretches out or retracts back to drive the front frame and the rear frame to generate relative angle deflection, at the moment, due to the fact that the front frame and the rear frame both generate relative position deflection, the turning radius is reduced in the steering process compared with a traditional front wheel steering type chassis, the turning radius of the chassis in the turning process is smaller, and the steering efficiency of the chassis is improved. And turning and U-turn can be realized in a smaller area range.
本发明提供了一种多功能铰接式底盘及拖拉机,多功能铰接式底盘包括前车架、后车架、铰接轴和伸缩驱动机构,前车架与后车架之间通过铰接轴进行铰接,且铰接轴沿高度方向进行布置;后车架包括固定车架和转动车架,固定车架通过铰接轴与前车架铰接,转动车架沿其自身长度方向转动地连接在固定车架上;伸缩驱动机构的第一端铰接在前车架上,伸缩驱动机构的第二端铰接在固定车架上。本申请通过伸缩驱动机构伸出或缩回,驱动前车架和后车架发生相对角度偏转,此时因为前车架和后车架均发生相对位置偏转,因此在转向过程中相对于传统的前轮转向式底盘减小了转弯半径,使底盘在进行转弯过程中转弯的半径更小,能够在面积更小的范围内实现转弯和调头。
