1、 本科毕业设计 题目题目: 乘用车膜片弹簧离合器设计 学学 院院: : 汽车与交通工程学院 专专 业业: : 交通运输专业 学学 号号: : 学生姓名学生姓名: : 指导教师指导教师: : 日日 期期: : I 摘 要 汽车从启动到行驶的整个过程中,经常需要使用离合器,而膜片弹簧离合器在现 今社会应用的更是广泛。所以本次设计膜片弹簧离合器,在发动机与变速器之间能逐 渐接合,从而保证汽车能更加平稳起步的前提下,设计新式的拉式膜片弹簧离合器, 使其结构更加简单。 在设计过程中,最初列出设计方案,然后对膜片弹簧离合器的主要参数进行计算, 确定膜片弹簧、离合器盖、从动盘、压盘、扭转减震器等的结构尺寸,
2、最后参照机械 设计手册,运用CAD绘图软件画出相应的离合器装配图以及零件图。 本次设计包括膜片弹簧离合器主要参数选取,扭转减震器、从动盘总成、离合器 盖总成和膜片弹簧的结构确定,尺寸计算和强度校核。画出CAD零件图和装配图。 在本次离合器设计中,最终设计出了膜片弹簧离合器,比传统的离合器性能更好, 另外还设计了扭转弹簧,可以防止离合器发生共振。 关键词: 乘用车: 膜片弹簧离合器: 扭转减震器 II Abstract Car from the start to the whole process of traveling, often need to use the clutch, while
3、 the diaphragm spring clutch applications in todays society is more extensive. Therefore, the design of the diaphragm spring clutch between the engine and transmission can be gradually bonding, thus ensuring the car more stable and start the premise, to design the new pull-type diaphragm spring clut
4、ch, its structure is more simple. In the design process, the beginning column program, prepare a draft reference textbook to calculate the main parameters of the diaphragm spring clutch to determine the diaphragm spring clutch cover, driven plate, pressure plate, reversing the structure of the shock
5、 absorbent. size, the last reference to the mechanical design manual, the use of CAD software to draw the clutch assembly drawing and part drawing. The design includes select the main parameters of the diaphragm spring clutch torsion damper, driven plate assembly, clutch cover assembly and the diaph
6、ragm spring structure to determine the sizing and strength check. Finally, with a CAD part and assembly drawing. In the clutch design, final design of the diaphragm spring clutch, better than the traditional clutch performance, also designed the torsion spring, you can prevent the clutch resonance.
