轮式装载机设计论文.doc

摘要 轮式装载机属于铲土运输机械类，是一种广泛用于公路、铁路、建筑、水电、港口和矿山等建设工程的土石方施工机械。具有作业速度快、效率高、机动性好、操作轻便等优点，对于加快工程建设速度，减轻劳动强度，提高工程质量，降低工程成本都发挥着重要的作用，是现代机械化施工中不可缺少的装备之一。本以模块的方式述了轮式装载机的发展以及用途、分类和相关参数、总体构造、传动系统、制动系统、转向系统、工作装置和液压系统的组成。在用途和分类中对装载机的发动机功率、传动形式、行走结构、装卸方式?做了简单的介绍。通过选用原则的叙述，使我们对装载机使用性能有进一步的了解。另外，简单列举了国内外。众所周知现在我国已成为全球瞩目的装载机生产大国，但我们还仅仅是制造“大”国，而不是制造“强”国。自主创新能力不足，缺少具有自主知识产权和较强国际竞争力的产品是根本原因。开发具有自主知识产权的核心技术，尽快缩短与国外大公司间的技术差距，提升产品的国际市场竞争力，是摆在 Abstract Wheel loader shovel soil mechanical belongs to transportation, is a widely used for highway, railway, construction, water and electricity, ports and mining and other construction engineering conditions of construction machinery. Work with speed, high efficiency and convenient operation, good mobility etc, and to speed up the construction speed, reduce labor intensity, improving engineering quality, reduce the cost for the project is an important role, is the modern mechanical construction of one of the indispensable equipment. The design for the module way discusses the development and application of the wheel loader, classification and related parameters, general structure, transmission system, braking system, steering system, work device and the composition of the hydraulic system. In the use of the loader and classification of engine power, transmission form, and walking, structure, loading and unloading way do briefly introduced. Through the selection principle of narrative that we use to loader have further understanding of performance. In addition, simple summarizes the current situation of the development of wheel loader. As is known to all now Chinas has become a global attention the loader production country, but we still only a manufacturing big countries, and not to make strong countries. The independent innovation ability is insufficient, with independent intellectual property rights and the lack of a stronger international competitiveness of the products was the reason. Development with independent intellectual property ri
