第1章绪论
1.1引言
汽车举升机在汽车维修行业是最重要、最基本的工具之一，是将汽车从一个高度提升至另一高度进行维修的设备，具有至关重要和不可替代的作用。
她能否正常运转会直接影响到维修车辆、维修人员的安全，甚至会直接影响到汽车维修业务的兴衰。
两柱式液压举升机具有承载力高、适应性强、维修及安装方便等优点。
它能够适应不同类型的车辆维修。
随着汽车工业的不断发展，汽车维修设备也发展到一个更高的阶段。
两柱式液压举升机的液压系统分析、研究对于正确合理的设计和使用，对于提高液压举升设备的工作品质和技术经济性能具有重要意义。
因而，对两柱式液压举升机的系统运动学、动力学的研究很有必要。
为以后的研发、改进提供必要的帮助。
本文针对液压举升机的特点和发展趋势，以现有的液压举升设备为基础，对举升机的液压系统进行设计。
1.2国内外汽车举升机液压系统状况
近年来，中国汽车业蓬勃发展，特别是轿车行业。
多年来轿车进入普通家庭的梦想已经成为现实，汽车维修行业也随之得到大力发展，各种维修设备的需求迅速扩大，汽车举升机是维修厂必备的，也
是最重要的维修机械之一。
不同的维修企业根据财力、维修项目、车间大小的不同，举升机需求类型也不相同。
根据调研，两柱举升机是当前被广泛采用的主流举升机，是经销商销量最大的举升机类型。
四柱举升机国产设备的价位在 1.0~3.5万元，进口品牌在 1.8~4.5万元，价格随着举升机吨位的提高而增加，可适用于大多数车型。
可是四柱举升机宽大的支承装置往往会妨碍工人干活。
主要用户为快速保养为主的小型企业，因为快速保养业务需要车辆能够快速升降，如果购买两柱举升机则需要在车辆起降过程中花费一些时间。
同时4S店对四柱举升机也有很大的需求。
剪式举升机使用方便，不用时不占空间，受到很多实力雄厚的特约维修站的欢迎，这也是未来举升机的发展方向，一般国产设备价位在1.0~4.0万元，进口产品在1.5~4.5万元。
但剪式举升机较为精密，做工不好或者设计不好就容易导致台面不平、单边升降等危险发生，如果利用剪式举升机作四轮定位仪的平台，要求就更加严格。
对于国内使用较为普遍的一些两柱举升机品牌而言，国产的价位约在0.6~1.4万元，进口的约在1.8~2.8万元。
