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 separate.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. In this paper,the constructional features and principles of operation of recently developed new style pull-type diaphragm spring clutch are described in contrast with the traditional push-type diaphragm spring clutch.In the same dimension,pull-type diaphragm spring by optimum design is better than push-type,in respect of stability of reservation coefficient maximum equivalent stress of diaphragm and magnitude of declutching force.Then,the load-deflection characteristics and stress-deflection characteristics of pull-type diaphragm spring are analysis in detail.Base on these analyses,the selection of main parameters and design of this spring are discussed.The pull-type diaphragm spring clutch possesses many advantages,therefore pull-type diaphragm spring clutch is a very prospective motor vehicle clutch.
