本科毕业生设计 东风自卸车的改装设计 院系名称： 汽车与交通工程学院 专业班级： 车辆工程 07-2班 学生姓名： 贺巍 指导教师： 吕德刚 职 称： 讲 师 黑 龙 江 工 程 学 院 二○一一年六月 The Graduation Design for Bachelors Degree The Modify and Design of Dongfeng dump truck Candidate：He Wei Specialty：Vehicle Engineering Class： 07-2 Supervisor：Lv DegangHeilongjiang Institute of Technology 2011-06·Harbin 摘 要 自卸车，是指通过液压或机械举升而自行卸载货物的车辆。由自卸车底盘、举升机构总成、液压系统总成、锁紧机构总成、大箱总成5大块组成。本次设计主要包含有车厢，取力器，液压缸，整车布置等内容。选择本课题充分考虑了研究课题对车辆工程专业学生学习和工作的指导作用，能够使我们了解专用汽车改装设计方法，通过本课题的研究我们可以完成理论课程的实践总结，获得一定的工程设计工作方法和经验。进行相关的设计，可以解决供需矛盾，培养正确的研究方法、理论联系实际的工作作风、严肃求实的学习态度，锻炼使用工具软件的能力，提高综合设计的能力这次设计为我们了解专用车带来了很大的好处，通过设计我们知道了专用车的结构形式和举升样式等知识，对我们以后的工作有很大的益处。 关键词：东风自卸车；自卸车；专用汽车；专用车设计；举升机构；液压系统； ABSTRACT Dump truck, is also called the car to through the hydraulic or mechanical lifting and unloading goods to the vehicle. By dump of lifting mechanism of assembly, chassis, hydraulic system assembly, locking mechanisms assembly, big box of five large assembly. This design mainly contains the car, take the force, the hydraulic cylinder, the arrangement of the whole car, etc. Choose this topic full consideration of the research on vehicle engineering students to study and work guidance, can make us understand special automobile refitting design method, through this topic research we can complete theory course the practice, access to certain engineering design work methods and experience. Related design, can solve the contradiction between supply and demand, the research methods, cultivate correct theory with practice work style, serious realistic learning attitude, exercise the ability of tool use software, improve the overall design of the ability for us to understand this design has brought great benefits a., through the design we know the special structure of the form and lifting style and etc, to our knowledge later work to have the very big profi
