摘 要
離合器在機(jī)械傳動(dòng)系中是作為一個(gè)獨(dú)立的總成而存在的，它是汽車傳動(dòng)系中直接與發(fā)動(dòng)機(jī)相連接的總成。汽車從啟動(dòng)到行駛的整個(gè)過程中，經(jīng)常需要使用離合器。它的作用是使發(fā)動(dòng)機(jī)與變速器之間的組件接合，從而保證汽車平穩(wěn)起步；暫時(shí)切斷發(fā)動(dòng)機(jī)與變速器之間的聯(lián)系，以便于換擋和減少換擋的沖擊；當(dāng)汽車緊急制動(dòng)時(shí)能起到分離的作用，防止變速器等傳動(dòng)系統(tǒng)過載，起到一定的保護(hù)作用。
本次所設(shè)計(jì)的離合器是膜片彈簧離合器，此設(shè)計(jì)說明書以SF2310-4時(shí)風(fēng)低速貨車為本次設(shè)計(jì)的參照車型。說明了輕型貨車膜片彈簧離合器的結(jié)構(gòu)形式，參數(shù)以及計(jì)算過程，按照離合器系統(tǒng)的設(shè)計(jì)步驟和要求，對(duì)摩擦片外徑D進(jìn)行確定，離合器后備系數(shù)β進(jìn)行確定，單位壓力P0進(jìn)行確定，以及從動(dòng)盤設(shè)計(jì)，包括從動(dòng)片設(shè)計(jì)和從動(dòng)盤轂進(jìn)行設(shè)計(jì)，主動(dòng)部分的設(shè)計(jì)，包括壓盤、離合器蓋設(shè)計(jì)、彈性從動(dòng)片設(shè)計(jì)，其中離合器蓋的設(shè)計(jì)只是簡(jiǎn)單的設(shè)計(jì)，操縱機(jī)構(gòu)的設(shè)計(jì)是大體上計(jì)算出踏板的行程、踏板力是否符合人體工程學(xué)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.
Key words: Clutch; Design; Diaphragm spring; Driven plate; Pressure plate; Friction plate
