免费下载优秀毕业论文车辆工程--客车底盘，校车，技术 Abstract The next 10 years, a period of rapid economic growth in the Chinese city operation bus gradually embarked on a mature period, the city bus will be in the updated-for-peak. With our nation’s support of developing the public transportation , the presence safety problems in school bus ,the enlargement market of the domestic professional school buses ,and the further clarification of some relevant standards and specifications ,school buses are bound to be the main supporting point in the future automobile marketWill also further promote the entire passenger car market, to lay the foundation for future passenger car market to mature And the core point of the bus lies in the level of the chassis technologyLeap forward in the chassis in the field of Chinese small and medium-sized city buses has become a shining star, to become the darling of the small and medium-sized city bus about 7 meters. Over the past few years leap forward in the chassis has been committed to small and medium-sized city bus market research and product development, of 7 m small bus has become recognized as one of the mainstream products industry This paper introduces the technology of Yuejin chassis parts achievementFrom the chassis power, emission, braking and other key aspects of the problem of Yuejin chassis technology, maintenance, repair and chassis industry advanced technology cognition has important practical significance. Key words:passenger-carrying chassis,school bus,technology 目 录 摘 要 1 第1章 绪论 5 1.1 公共交通将带动客车需求的扩大 5 1.2 各地销售状况 5 第2章 跃进底盘构造与现状 8 2.1 底盘性能的认识 8 2.2 底盘的组成 9 2.3 跃进底盘系列分类 9 2.3.1 村村通系列 9 2.3.2 旅游客车系列 10 2.3.3 校车系列 11 2.3.4 公交系列 12 第3章 跃进底盘动力性与排放 14 3.1 跃进底盘索菲姆发动机 14 3.1.1 柴油发动机的电控共轨技术 14 3.1.2发动机的基本参数 14 3.1.3 电控共轨系统的架构 16 3.1.4 电子控制策略 16 3.2部分外购发动机性能 18 3.2.1 锡柴发动机 18 3.2.2 玉柴发动机 18 3.3发动机与排放标准 19 3.3.1 采用增压中冷技术 19 3.3.2 电子控制技术 19 3.3.3 废气再循环EGR 19 第4章 跃进底盘制动系 20 4.1 制动器作用及分类 20 4.2 鼓式制动器 20 4.2.1 鼓式制动器操作机构 20 4.2.2 鼓式制动器优缺点 21 4.3 盘式制动
