摘要 随着社会的发展，人口的急剧增长，土地越来越稀缺，可是科学在进步，科技在发展，随着城市的进步，车辆的增多，交通越来越不便，当车成为人类主要的代步工具后，停车问题也日益严重，如果按照以前的做法，一个车停一个位置，那样对于土地的利用是不是很浪费，所以，关于设计立体车库提上日程。 立体车库设备是为了专门的实现各种车辆自动停放仓储设备。机械式立体停车库可充分的利用土地资源，发挥空间的优势，最大限度的停放大量车辆，已经成为解决城市静态交通问题重要途径。本课题以较典型的液压升降横移式立体车库为研究对象，综合的考虑立体车库制造成本和运行效率的双重因素。而液压系统与传统机械系统相比，由于具有更精确，重量轻、体积孝运动惯性孝反应速度快、工作平稳、操纵控制方便、可实现大范围无级调速、可自动的实现过载保护、当采用电液联合控制后，不但可实现更高程度的自动控制的过程，而且可以实现遥控等很多优点，成为立体车库传动系统的首要选择，本设计的主要内容包括立体停车库机械系统原理设计，液压系统微推送力确定等。通过电机链条实现载车平台的平移升降，液压缸实现载车平台的微平移，实现车辆的存取过程。实现立体车库占用空间少，存取方便的功能。 因为其独特的特点，立体车库被广泛用于，酒店，医院，商场，机关单位和居民楼小区内。液压升降立体车库的组成，大概可以分为三个部分：传动机构部分，车库结构部分，控制部分。传动机构部分分为四个部分：升降部分，平移部分，载车版部分和伸缩部分。 关键词：机械设计；立体车库；液压系统 Abstract With the developme
