The invention discloses a hydrostatic driving wheel-track combined universal chassis of a high-ground-clearance rape windrower. The universal chassis comprises a rack, a cab arranged above the rack and an engine, and is characterized by also comprising a hydraulic walking driving system, a steering driving control system, and a front wheel triangular track assembly, left and right steering rear wheels and a steering axle which are arranged at the bottom of the rack; the hydraulic driving system comprises a walking hydraulic pump and a steering hydraulic pump which are connected to an engine power output shaft, an output oil port of the walking hydraulic pump is connected to a left walking motor and a right walking motor respectively through an electric proportional control valve set and aflush valve, and output shafts of the left walking motor and the right walking motor are connected to a driving wheel of the front wheel triangular track assembly respectively. According to the hydraulic walking system provided by the invention, a one-pump double-motor mode is adopted, active flow distribution is conducted on the two driving motors of the front wheel by detecting the rotating angle of the rear wheels relative to the rack, the hydraulic walking driving system is simplified, and the front wheel actively follows the rear wheel to steer, steering is flexible, and the structure issimple.
本发明公开一种高地隙油菜割晒机静液压驱动轮履组合通用底盘,包括机架、安装于机架上方的驾驶室和发动机,其特征在于:还包括液压行走驱动系统、转向驱动控制系统以及安装于机架底部的前轮三角履带总成、左右转向后轮及转向桥;所述液压驱动系统包括与发动机动力输出轴相连的行走液压泵和转向液压泵,所述行走液压泵的输出油口经电比例控制阀组和冲洗阀后分别与左、右行走马达连接,所述左、右行走马达的输出轴分别与前轮三角履带总成的驱动轮连接。本发明液压行走系统采用一泵双马达方式,通过检测后轮相对机架转角对前轮2个驱动马达进行主动流量分配,简化了液压行走驱动系统,实现了前轮主动跟随后轮转向,转向灵活,结构简单。
