基于ProE的离合器的三维实体建模.doc

摘 要 汽车是现代生活中不可或缺的交通工具。近年来汽车设计和制造技术的进步有目共睹。为了进一步提高产品性能,延长使用寿命,普通机械式离合器技术同样也产生了令人注目的变化。无论从结构特性、产品工艺性能,还是控制技术方面,机械离合器的技术进步从某种程度上反映了设计观念的发展,以及将来可能的技术走势。离合器是汽车传动系中的重要部件，它的构造特性与发展和传动系紧密相关，本文主要是对载重2吨轻型汽车的膜片式弹簧离合器进行设计。 离合器设计的内容主要包括压盘总成、从动盘总成、膜片弹簧三个部分。首先，对离合器各零件的参数、尺寸、材料、及结构进行设计，然后使用Pro/E软件画出推式膜片弹簧的装配及零件的三维图形。最后进行机构运动仿真。 本次的设计对原有离合器的设计提出优化和修改的建议，对其以后的设计过程起参考作用。本文还重点研究了膜片弹簧在分离过程中的受力，对受力过程进行数学分析，并对其进行校核，以提高膜片弹簧离合器的使用寿命，使膜片弹簧离合器在工作过程中处于最佳状态。 关键词：离合器；膜片弹簧；摩擦片；参数设计。 ABSTRACT Automotive is an integral part of modern life transportation.Of late years, the development in design and manufacturing technique of automobile is obvious to all. In order to improve product performance and to extend service life,technique on the general machinery clutch produced attentional changes too.The technique development of the machinery clutch, whether its design feature,processing property or control technique, reflected development of the design concept and its future possible technique trend to a certain extent. The clutch is one important part in the auto power train ,in the internal combustion engine as the power of mechanicaldrive auto ,the clutch took an independent part exists. This paper is the single-car theca spring clutch design. The content of clutch design main contain three parts: driven disc design, diaphragm-spring design and the driving disc design. Fist,The article studied in each clutch accessory’s material, technique in manufacture and machining and choosing project, then uses the Pro/E software to picture the three dimensional image of the Assembly and the Components. Finally the mechanism movement simulation. The design of the original design of the clutch to optimize and modify the proposal, its future role in the design process from the reference.This article emphasize in studying the diaphragm-spring characteristic, analyzing the dynamics and the mathematics in separation process stress, optimizing every date about the diaphragm-spring, for improving use lifetime of di
