The invention discloses a steering mechanism, a chassis and a field operation vehicle. The steering mechanism comprises a plurality of universal transmission shafts connected in sequence, at least onesupport frame and at least one pair of steering wheels, one end of each universal transmission shaft is connected with one steering wheel, and the other end of each universal transmission shaft is connected with the other steering wheel; one of the pair of steering wheels is connected with a universal transmission shaft through a supporting frame, and the supporting frame is hinged to a linear driving unit. According to the walking chassis with the adjustable wheel track, the steering mechanism capable of achieving linkage steering is designed, and through transmission of the universal transmission shafts, the synchronism of steering actions of the steering wheels on the two sides and the consistency of steering angles can be met; steering angle transmission of the steering mechanism adopts speed increasing and changing transmission, so that corner loss caused in the transmission process can be reduced, and steering synchronism and angle consistency are better.

    本发明公开了一种转向机构、底盘及田间作业车辆,一种转向机构,包括多个顺序连接的万向传动轴、至少一个支撑架以及至少一对转向轮,多个万向传动轴的一端连接的一个转向轮,另一端连接另一个转向轮;一对转向轮中的一个转向轮通过支撑架连接万向传动轴,支撑架铰接直线驱动单元。本发明针对轮距可调的行走底盘,设计了可以联动转向的转向机构,通过万向传动轴的传动,可满足两侧转向轮的转向动作的同步性和转向角度的一致性;本发明的转向机构的转向角度传递采用升速变速传递可以减少传递过程中带来的转角损失,使转向同步性和角度一致性更优。
