丘陵山地姿态调整轮式拖拉机的设计与仿真

针对丘陵山地拖拉机作业环境复杂,对拖拉机的稳定性、通过性和地形适应性要求高的突出问题,设计了一种可进行姿态调平的丘陵山地拖拉机,主要由姿态调整后驱动桥、姿态调整前驱动桥、发动机及电液控制系统组成。姿态调整后,驱动桥设置有可独立回转摆动的轮边减速机构,实现了驱动桥刚性结构柔性调节。姿态调整前驱动桥可围绕拖拉机摇摆轴进行姿态调节。电液控制系统实时监测前、后驱动桥与地面间的坡度夹角变化,自动调节驱动桥的摆动姿态,始终使机身处于水平姿态,提高整机作业稳定性。

Design and Simulation of Wheel Tractor with Full Attitude Adjustment in Hilly and Mountain Areas

In view of the complex working environment of tractors in Hilly and mountainous areas and the high requirement for tractors'stability,trafficability and topographic adaptability,a hilly and mountainous tractor with attitude leveling was studied and designed.Major components:rear drive axle with adjustable joint,front drive axle with adjustable joint,engine,electro-hydraulic control system,etc.Rear drive axle with adjustable joint is equipped with a wheel-side deceleration mechanism which can swing independently to achieve flexible adjustment of the rigid structure of the driving axle.The front drive axle can adjust the attitude around the tractor swing state.The electro-hydraulic control system can monitor the slope angle between the front and rear driving axles and the ground in real time,automatically adjust the swing attitude of the driving axle,and always keep the fuselage in a horizontal attitude,so as to improve the stability of the whole machine.
