摘 要
離合器在機械傳動系中是作為一個獨立的總成而存在的，它是汽車傳動系中直接與發(fā)動機相連接的總成。汽車從啟動到行駛的整個過程中，經(jīng)常需要使用離合器。它的作用是使發(fā)動機與變速器之間的組件接合，從而保證汽車平穩(wěn)起步；暫時切斷發(fā)動機與變速器之間的聯(lián)系，以便于換擋和減少換擋的沖擊；當汽車緊急制動時能起到分離的作用，防止變速器等傳動系統(tǒng)過載，起到一定的保護作用。
本次所設計的離合器是膜片彈簧離合器，此設計說明書以SF2310-4時風低速貨車為本次設計的參照車型。說明了輕型貨車膜片彈簧離合器的結構形式，參數(shù)以及計算過程，按照離合器系統(tǒng)的設計步驟和要求，對摩擦片外徑D進行確定，離合器后備系數(shù)β進行確定，單位壓力P0進行確定，以及從動盤設計，包括從動片設計和從動盤轂進行設計，主動部分的設計，包括壓盤、離合器蓋設計、彈性從動片設計，其中離合器蓋的設計只是簡單的設計，操縱機構的設計是大體上計算出踏板的行程、踏板力是否符合人體工程學要求。

Abstract
The clutch is present as a separate assembly in the mechanical drive train, which is the assembly directly connected to the engine in the driveline. Car from the start to the entire process of driving, often need to use the clutch. Its role is to make the engine and the transmission between the components can be connected to ensure a smooth start of the car; temporarily cut off the connection between the engine and the transmission in order to shift and reduce the impact of the shift; when the car can play an emergency brake The role of separation, to prevent transmission and other transmission system overload, play a protective role.
This design of the clutch is a diaphragm spring clutch, this design to SF2310-4 when the wind low-speed truck for the design of the reference model. The structure, parameters and calculation process of the light truck diaphragm spring clutch are described. The outer diameter D of the friction plate is determined according to the design steps and requirements of the clutch system. The clutch backup coefficient β is determined and the unit pressure P0 is determined. The design of the drive plate, including the design of the driven plate and the driven plate hub, the design of the active part, including the pressure plate, the clutch cover design, the elastic follower design, in which the design of the clutch cover is simply designed, the design of the steering mechanism Is to calculate the pedal of the trip, pedal force is ergonomic requirements.
