摘    要
　　　離合器位于發(fā)動(dòng)機(jī)和變速箱之間的飛輪殼內(nèi)，用螺釘將離合器總成固定在飛輪的后平面上，離合器的輸出軸就是變速箱的輸入軸。在汽車(chē)行駛過(guò)程中，駕駛員可根據(jù)需要踩下或松開(kāi)離合器踏板，使發(fā)動(dòng)機(jī)與變速箱暫時(shí)分離和逐漸接合，以切斷或傳遞發(fā)動(dòng)機(jī)向變速器輸入的動(dòng)力。
　　離合器作為汽車(chē)傳動(dòng)系統(tǒng)的重要部件，離合器的功用主要有3個(gè)：保證汽車(chē)平穩(wěn)起步前汽車(chē)處于靜止?fàn)顟B(tài)；便于換檔，汽車(chē)行駛過(guò)程中，經(jīng)常換用不同的變速箱檔位，以適應(yīng)不斷變化的行駛條件；防止傳動(dòng)系過(guò)載。
　　　離合器從動(dòng)盤(pán)是離合器的重要部件之一。其性能的優(yōu)劣直接影響離合器的性能。為了確保離合器的工作性能，使其處于良好的工作狀態(tài)，在離合器裝配前需要對(duì)從動(dòng)盤(pán)進(jìn)行性能檢測(cè)，其中，對(duì)其做疲勞壽命試驗(yàn)是一個(gè)重要的步驟。
　　　汽車(chē)離合器從動(dòng)盤(pán)扭轉(zhuǎn)壽命試驗(yàn)機(jī)是汽車(chē)零部件壽命試驗(yàn)的重要試驗(yàn)設(shè)備。研究開(kāi)發(fā)自動(dòng)化程度較高的此類試驗(yàn)機(jī)，對(duì)于提高汽車(chē)離合器甚至是整臺(tái)汽車(chē)的產(chǎn)品質(zhì)量有著較廣泛的實(shí)用性。同時(shí)它對(duì)促進(jìn)國(guó)內(nèi)汽車(chē)零部件工業(yè)的發(fā)展有著重要意義。
　　　目前國(guó)內(nèi)的大多數(shù)試驗(yàn)機(jī)都是在離合器盤(pán)總成固定的情況下進(jìn)行試驗(yàn)的,這并不符合離合器盤(pán)總成的實(shí)際工況，論文提出了一種新型汽車(chē)離合器從動(dòng)盤(pán)扭轉(zhuǎn)壽命試驗(yàn)機(jī)——離合器盤(pán)高速旋轉(zhuǎn)疲勞壽命試驗(yàn)機(jī)。該試驗(yàn)機(jī)可以是在盤(pán)高速旋轉(zhuǎn)的情況下進(jìn)行試驗(yàn)的,更符合離合器的實(shí)際工況。
　　　論文詳細(xì)介紹了新型扭轉(zhuǎn)疲勞壽命試驗(yàn)機(jī)的選型分析、研制過(guò)程、性能特點(diǎn)、組成及測(cè)控原理。

ABSTRACT
　　
　　Clutch pedal in the engine and gearbox between the flywheel shell, with screw will be fixed in the clutch assembly after the plane of the flywheel, clutch gearbox output shaft is the input shaft. In the process of moving vehicle, the driver may need to push or release the clutch pedal so that the engine and gearbox temporary separation and progressive joint, to cut off the engine or transmission to the transmission input power.
　　Clutch Transmission System as an important vehicle parts, the clutch has three main functions: to ensure a smooth start before the vehicle in a stationary vehicle; facilitate the shift, the process of moving car, often used for the transmission of different stalls to adapt to changing The traffic conditions prevent the transmission of the overload.
　　This machine is one of the important parts. It directly impact on the performance of the merits of clutch performance. In order to ensure that the work of clutch performance, it is good working condition, in the clutch assembly before the need for a performance-driven detection, which do their fatigue life test is an important step.
　　Car driven clutch reverse the life-testing machine is the life test of automotive components important test equipment. A higher degree of automation research and development of such testing machine for raising automobile clutch or even the entire automotive product quality has a wider relevance. At the same time its domestic auto parts industry to promote the development of great significance.
　　Most of the current domestic testing machine is fixed in the clutch disc assembly of the circumstances test, this does not meet the clutch disc assembly of the actual conditions, paper puts forward a new car driven clutch reverse-life test machine -- -- High-speed rotating disc clutch fatigue life testing machine. The testing machine can be set in the high-speed rotation of the circumstances of the trial, more in line with the actual conditions clutch.
　　Papers detail on the new plane reversed fatigue life test of the selection, development process, features, composition and monitoring principles.

Key words: clutch, high-speed rotation, fatigue life testing machine
