A tractor four-wheel-drive transmission chassis with a waist bending and twisting function comprises a front box body and a rear box body, front wheels are installed on the left side and the right side of the front box body respectively, rear wheels are installed on the left side and the right side of the rear box body respectively, a waist bending and twisting device is arranged between the front box body and the rear box body, and a PTO assembly is arranged at the rear end of the rear box body. A waist twisting shaft sleeve of the bowing and waist twisting device is connected with the front box body and arranged at the rear end of the input shaft in a sleeving mode, a bowing and waist twisting support of the bowing and waist twisting device is rotationally connected with the rear box body, the bowing and waist twisting support and the waist twisting shaft sleeve are oppositely positioned in the axial direction, and the bowing and waist twisting support can rotate relative to the waist twisting shaft sleeve. The front box body, the bowing and 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 and waist-twisting support and the rear box body, the steering radius is reduced, the steering capacity of the tractor is improved, and the requirement for deflection driving of front wheels and rear wheels of the tractor on irregular road surfaces is met. And the tractor adapts to complex terrains of hills and mountains.

    一种具有折腰扭腰功能的拖拉机四驱传动底盘,包括前箱体和后箱体,前箱体的左右两侧分别安装有前轮,后箱体的左右两侧分别安装有后轮,前箱体和后箱体之间设有折腰扭腰装置,后箱体的后端设有PTO总成。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。
