轻型汽车的膜片式弹簧离合器设计 摘要:汽车技术飞速发展，各国路况水平逐渐完善，要求发动机高转速、高功率和汽车电子高科技，各方面都在向着高精尖的技术层次发展，人们的使用需求和要求也在日渐提高，对离合器性能的要求也与日俱增。推式膜片弹簧离合器不能满足实际需要，拉式膜片弹簧离合器可满足实际需要逐渐取代了它。由于其操作形式不便，正慢慢被自动操纵这种新的发展形式而取代。因此，离合器的发展趋势很明显，拥有很高的结构性能和满足使用要求的寿命，并且能够在高转速确保良好的工作状态，拥有简洁的部件构成和很高的传递效率。 本文根据离合器技术发展的具体要求，对某汽车离合器进行了设计。首先，根据当前离合器研究现状，包括功用、工作原理、具体的设计要求，对本文要完成的各项内容和所要完成的成果进行了全面概要的安排。然后，对离合器的结构进行了详细的设计，根据相关标准和要求，重点介绍了离合器构成部件及其构成方式的选取方案；根据设计要点，对主要构成部件的设计进行了详细的阐述。最后，对离合器构成部件的具体参数进行了科学的计算和优眩 关键词：离合器；摩擦片；膜片弹簧；从动盘 Diaphragm spri
