The invention particularly relates to a hillside tractor chassis with posture adjustment and walking self-adaption functions. The hillside tractor chassis solves the problems that a tractor is poor in slope adaptability, low in anti-overturning performance, low in obstacle crossing performance and insufficient in smoothness. The invention discloses a hillside tractor chassis with posture adjustment and walking self-adaption functions. A main body part comprises two driving frames and a longitudinal connecting frame; a horizontal bracket is arranged on the lower side of the longitudinal connecting frame; a central transmission box is integrally fixed in the middle of the lower beam; wheel edge transmission boxes are arranged on the left side and the right side of the driving frame; the transmission part comprises a transfer case; a longitudinal outer rotating shaft and a longitudinal inner rotating shaft are arranged in an inner cavity of the longitudinal connecting frame; the two ends of the longitudinal outer rotating shaft and the two ends of the longitudinal inner rotating shaft are in transmission connection with the input ends of the four wheel edge transmission boxes respectively. The height difference between the driving wheels on the left side and the right side is automatically adjusted through the parallel four-rod leveling mechanism, the directions and postures of the driving wheels and the machine body are kept unchanged, then the walking self-adaption function is achieved, and the requirement for slope operation of the tractor is met.
本发明具体是一种具有姿态调整和行走自适应功能的山地拖拉机底盘,解决了拖拉机坡地适应性差、抗翻倾性能低、越障性能低、平顺性不足的问题。一种具有姿态调整和行走自适应功能的山地拖拉机底盘,主体部分包括两个驱动架和纵向连接架;纵向连接架的下侧设置有水平托架;下横梁中部一体固定有中央传动箱;驱动架的左侧、右侧均设置有轮边传动箱;传动部分包括分动箱;纵向连接架的内腔设置有纵向外转轴和纵向内转轴;纵向外转轴的两端、纵向内转轴的两端分别与四个轮边传动箱的输入端传动连接。本发明利用平行四杆调平机构自动调整左右侧驱动轮的高度差,保持驱动轮和机身方位、姿态不变,进而实现行走自适应的功能,满足拖拉机坡地作业的要求。
