1 前言 目前林用车辆很需要一种通用底盘,在这种通用底盘上可以装备各种单工序、多工序伐区机械和伐区联合机械。根据伐区工作的特殊环境和为改善驾驶员的工作条件,林用车辆通用底盘转向系统可以采用双向全液压双操作的铰接式车架转向,这种转向优于目前国内工程车辆上和集材—80拖拉机上用全液压操纵铰接式车架转向,其特点首先是在通过泥泞和沼泽地时用滑阀转向,转向迅速,能做到鸭步行,使通过能力增强,保
1 Foreword At present, forest vehicles are in need of a universal chassis. In this universal chassis, a variety of single-process, multi-process cutting area machinery and cutting area combined machinery can be equipped. According to the special circumstances of the cutting area work and to improve the working conditions of the driver, the universal chassis steering system for forest vehicles can be articulated frame steering with bi-directional full hydraulic double operation. This steering is superior to the current domestic construction vehicles and skidding -80 tractor steering with hydraulic steering articulated frame, the first characteristic is the muddy and wetlands through the use of slide valve steering, steering quickly, can duck walk, so that through the ability to enhance the security
