A bowing and twisting device for a hilly and mountain tractor is arranged between a front box body and a rear box body of the tractor, a twisting shaft sleeve of the bowing and twisting device is connected with the front box body and arranged at the rear end of an input shaft in a sleeved mode, a bowing and twisting support of the bowing and twisting device is rotationally connected with the rear box body, and the bowing and twisting support and the twisting shaft sleeve are oppositely positioned in the axial direction. The bowing waist-twisting support can rotate relative to the waist-twisting shaft sleeve, so that the front box body, the bowing waist-twisting support and the waist-twisting shaft sleeve can rotate in a bowing mode relative to the rear box body, the front box body and the waist-twisting shaft sleeve can rotate in a waist-twisting mode relative to the bowing waist-twisting support and the rear box body, the steering radius is reduced, and the steering capacity of the tractor is improved. Deflection driving requirements of front and rear wheels of the tractor on irregular road surfaces are met, the tractor is made to adapt to complex terrains of hills and mountains, and trafficability of the tractor on non-flat operation road surfaces is improved.

    一种用于丘陵山地拖拉机的折腰扭腰装置,设在拖拉机的前箱体和后箱体之间,折腰扭腰装置的扭腰轴套与前箱体连接并套设在输入轴的后端,折腰扭腰装置的折腰扭腰支架与后箱体转动连接,折腰扭腰支架和扭腰轴套沿轴向相对定位,折腰扭腰支架能够相对于扭腰轴套转动,使前箱体、折腰扭腰支架和扭腰轴套能够相对于后箱体进行折腰转动,并使前箱体和扭腰轴套能够相对于折腰扭腰支架和后箱体进行扭腰转动,减小转向半径,提升拖拉机的转向能力,满足不规则路面上拖拉机前后轮的偏斜行驶需求,使拖拉机适应丘陵山地的复杂地形,提升了拖拉机在非平坦作业路面的通过性。
