山地林业履带拖拉机底盘(简称底盘,下同)是广西壮族自治区科委下达柳州林业机械厂研制的重大项目。我国山区、丘陵占总土地面积的66%,山区耕地占总耕地面积的46%。我国南方林区山高坡陡、地势复杂。因此,研制出一种能适应山区多种机械机具作业的动力机械,对实现山区农业、林业机械化,促进山区经济的发展都有积极的意义。一、底盘调平的必要性普通型拖拉机(包括履带式和轮式)在横坡地上作业的主要缺点是:静态和动态稳定性差;朝坡上侧转向或坡上侧的车 The mountain forestry tracked tractor chassis (referred to as the chassis, the same below) is a major project developed by Guangxi Zhuang Autonomous Region Science and Technology Commission under the Liuzhou Forestry Machinery Plant. The mountains and hills in China account for 66% of the total land area, and the cultivated land in mountainous areas accounts for 46% of the total cultivated land. The hilly slopes and complex terrains in the forest areas in South China are steep. Therefore, the development of a kind of power machinery that can adapt to the operation of a variety of machinery and equipment in the mountainous area has a positive significance for the realization of mountain agriculture, forestry mechanization, and the promotion of economic development in mountain areas. First, the necessity of chassis leveling The main disadvantages of ordinary tractors (including tracked and wheeled) on the cross-slope are: static and dynamic stability is poor; the upper side of the slope to the side of the slope or slope of the car
