摘    要
離合器是客車傳動(dòng)系中直接與發(fā)動(dòng)機(jī)相連接的總成，其功用是切斷和實(shí)現(xiàn)對(duì)傳動(dòng)系統(tǒng)的動(dòng)力傳遞，以保證客車起步時(shí)將發(fā)動(dòng)機(jī)與傳動(dòng)系平順地接合，確保客車平穩(wěn)起步；在換檔時(shí)將發(fā)動(dòng)機(jī)與傳動(dòng)系分離，減少變速器中換檔齒輪之間的沖擊；在工作中受到最大的動(dòng)載荷時(shí)，能限制傳動(dòng)系所承受的最大轉(zhuǎn)矩，防止傳動(dòng)系各零件因過載而損壞；有效地降低傳動(dòng)系中的振動(dòng)和噪聲。在現(xiàn)代客車設(shè)計(jì)中，膜片彈簧式離合器應(yīng)用越來越廣泛。
本設(shè)計(jì)采用系統(tǒng)化設(shè)計(jì)方法討論膜片彈簧式離合器設(shè)計(jì)，并根據(jù)離合器的功能和結(jié)構(gòu)，把離合器分為主動(dòng)部分、從動(dòng)部分、分離機(jī)構(gòu)和操縱機(jī)構(gòu)等部分。根據(jù)其實(shí)際運(yùn)用要求，設(shè)計(jì)中詳細(xì)介紹離合器功能和工作原理，闡明了設(shè)計(jì)目的，分析了膜片彈簧及離合器從動(dòng)盤特點(diǎn)，并對(duì)離合器主要部分:摩擦片、壓盤、膜片彈簧等進(jìn)行了計(jì)算。

Clutch assembly design of bus and coach

Abstract
The clutch is the assembly, which directly connect the engine and the transmission. Its function is a cutting and realization in the power deliver of transmission, connecting the engine and the transmission are kept smoothly while the bus and coach is going to start, in order to insure the steady start of vehicle; While shifting gear, it separates the clutch and the gearbox, reduces the impact of shift gear between gears in the gearbox; While being dynamic load up to the maximum in the operate, it can limit the breakdown torque, pull out torque that the transmission depart bear, keep each parts of transmission from damage because of the overload; Reduce vibrate and noise within the transmission availably. Diaphragm clutch is used widely in modern vehicle.
The design uses a systematic design method to discuss the design of diaphragm spring clutch, and in accordance with the functions and structure of the clutch, divided into active part of the clutch, the driven part of the separation and manipulation of body parts. Practical application in accordance with its requirements, clutch design in detail the functions and working principle, designed to set out, analysis of the diaphragm spring and clutch plate follower characteristics, clutch and main parts: friction plate, pressure plate gap, such as diaphragm spring calculated. Clutch and main parts: friction plate, pressure plate gap, such as diaphragm spring calculated.

Key words: Clutch; Driven in part ; Diaphragm Spring; Development; Design
