本科学生毕业设计 HQ5050JGK高空作业车改装设计 系部名称： 汽车与交通工程学院 专业班级： 车辆工程07-4班 学生姓名： 李 超 指导教师： 赵雨旸 职 称： 副教授 黑 龙 江 工 程 学 院 二○一一年六月  The Graduation Design for Bachelors Degree Design on Aerial?platform truck of HQ5050JGK Candidate：Li Chao Specialty：Vehicle Engineering Class： 07-4 Supervisor：Associate Prof. Zhao Yuyang Heilongjiang Institute of Technology 2011-06·Harbin  摘 要 文中主要对HQ5050JGK高空作业车的二类底盘的选型和整体布置、动力传动装置设计分析、工作装置设计分析和控制系统设计分析，最后进行整车稳定性校核。 根据设计要求及其技术参数的要求，其设计思路为：根据高空作业车的举升质量要求，确定升降机的结构方案，然后确定汽车底盘及车辆的总体布置和控制系统。 在设计说明中，首先对升降机不同结构方案进行了比较，得出了设计方案，然后对负载进行分析计算，选择确定了整车的结构参数，然后根据负载和使用状况进行液压系统的设计。 文中主要完成的是HQ5050JGK高空作业车的总体结构设计、液压回路设计及传动装置工作装置的详细设计。高空作业车设计时按6单元展开，所有的设计工作都是围绕这6个单元展开的：高空作业车总体设计、举升机构的设计、工作装置的设计、动力传动装置的设计、安装保护装置、整车稳定性校核。 关键词：总体设计；举升机构；工作装置；动力传动装置；性能分析  ABSTRACT Focuses on HQ5050JGK aerial second class chassis selection and the overall layout, power transmission equipment design analysis, work equipment design analysis and control system design and analysis, the last vehicle stability check. According to requirements design and technical parameters of the requirements, design ideas are as follows: under the aerial lift vehicle quality requirements, to determine the structure of the lift program, and then determine the vehicle chassis and the overall layout and control system. In the design specification, the first lift programs with different structures are compared, obtained design program, then loads analysis and calculation, select the vehicle to determine the structural parameters and based load and use the situation to the hydraulic system design. In the main text to complete the HQ5050JGK Aerial overall structural design, hydraulic circuit design and gear detailed design of working device. Aerial vehicles designed to start by 6 units, all of the design work around these six units started. Aloft working car overall design、the design o
