普通式双柱汽车举升机设计

摘 要

汽车举升机设计是汽车修理设备设计的重要内容。普通式双柱举升机设计主要包括举升装置的设计、立柱的设计、支撑机构的设计、平衡机构的设计及保险机构的设计。其中举升装置的设计和平衡机构的设计是最关键的内容，直接影响汽车举升机的动力性和经济性的好坏，可以说立柱设计的好坏是决定举升机设计好坏的一项重要内容。本次普通式双柱汽车举升机设计主要是利用已给的数据对举升机进行了选择，利用汽车举升机设计的基本知识和实物测量对该举升机各总成的总体布置进行设计，根据汽车举升机的强度刚度分析与验算并进行相关的动力性、经济性和安全性计算以检验设计的合理性。通过本次毕业设计，充分了解和掌握了汽车举升机设计的步骤和方法，为我们以后毕业从事汽车行业设计的工作打下基础。

ORDINARY-TYPE DOUBLE CAR LIFT DESIGN

ABSTRACT

Auto lift equipment auto repair design is an important aspect of design. Ordinary-type lift double lifting device design include the design, column design, to support the design of institutions, balance of design and the design of insurance institutions. Lifting device in which the design and balance is the key to the design of the content, a direct impact on the power car lift and economy is good or bad, it can be said of the column design is good or bad design decision to lift a good or bad important content. The ordinary-type double car lift is designed to use the data to a choice of lift, car lift designed to use the basic knowledge and physical measurements of the lift the overall layout of the assembly to carry out design, according to the Automotive Lift check the strength and stiffness analysis and related power, economy and security in order to test the design of the calculation is reasonable. The adoption of the graduation project, and fully understand and master the design of the car lift and method steps for us to engage in the automobile industry after graduating from the work of laying a foundation design.Key words：the entire vehicle design , general arrangement , chassis , minitype passenger car

KEY WORDS: double lifts, synchronous lifting, lifting equipment
