重型自卸汽车离合器设计 摘 要 离合器作为直接连接发动机和传动系统一个独立存在的总成.主要包含主动部分,从动部分,压紧机构和操纵机构等四部分. 主动部分,从动部分和压紧机构是保证离合器处于接合状态并能传递动力的基本结构.操作机构是使离合器分离的机构.正是这四部分机构之间相互协调配合,已达到汽车起步时将发动机与传动系平顺地接合,换档式将发动机与传动系分离,减少变速箱内齿轮的冲击. 随着汽车发动机转速，功率的不断提高和汽车电子技术的发展，人们对离合器的要求越来越高。从提高离合器工作性能来看，传统的推式膜片弹簧离合器结构正逐渐的向拉式膜片弹簧离合器发展，传统的操作形式正向自动操作的形式发展。 因此，提高离合器的可靠性和延长其使用寿命，适应发动机的高转速，增加离合器的传递转矩的能力和简化操作，已经成为离合器的发展趋势。 关键词：离合器，从动部分，压紧机构，操纵机构 Design of Clutch of Heavy Dumper ABSTRACT The clutch is the lug connection engine and the transmission systems an exist independently total to become.He mainly includes the active division, follower division, compress tightly the mechanism and maneuvering gear etc. four-part cent. Active division, the follower division and compress tightly the mechanism is basic structure that guarantees that the clutch is placed in to join together the condition and can deliver the power also.Operate the mechanism is a mechanism that makes clutch seeparate.Exactly of this four-part cent mechanism moderates the fit mutually, joining together engine and transmissions fasten going smoothly while arriving the start of autocar already, the shift gear type fasten engine and transmissions separation, reduce the impact of the speed change case annular gear. Along with the autocar engine revolving speed, the power raises continuously and the development of the autocar electronics, the peoples request to the clutch is more and more high.Work from the exaltation clutch function to see, the traditional push make diaphragn spring structure of clutch positive gradual of to tension the diaphragn spring clutch of type deveolp, traditional form of operation just to the form development of the automatic operation. Therefore, the reliability of the exaltation clutch and lengthen its service life, adapt the high revolving speed of the engine, increase the ability and the simplification operations that the clutch delivers the turning moment, have already become the development trend of the clutch.
