【正文】 I 摘 要 汽車離合器位于發(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。在汽車行駛過(guò)程中，駕駛員可根據(jù)需要踩下或松開離合器踏板，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 。 目前，各種汽車廣泛采用的摩擦離合器是一種依靠主從動(dòng)部分之間的摩擦來(lái)傳遞動(dòng)力且能分離的裝置。 本 設(shè)計(jì) 主要是對(duì)中型貨車的膜片 式彈簧離合器進(jìn)行設(shè)計(jì) 。 根據(jù)車輛使用條件和車輛參數(shù)，按照 離合器 系統(tǒng)的設(shè)計(jì)步驟和要求， 首先進(jìn)行了基本參數(shù)的選擇，其次對(duì) 零部件設(shè)計(jì)：壓盤 、離合器蓋、彈性傳動(dòng)片，分離裝置，以及從動(dòng)盤 、 從動(dòng)片和從動(dòng)盤轂，操縱機(jī)構(gòu) ，扭轉(zhuǎn)減震器中的螺旋彈簧的設(shè)計(jì)。根據(jù)各零部件的工作條件，并對(duì)其進(jìn)行了相關(guān)校核 。 確保所設(shè)計(jì)的離合器能最大限度傳遞發(fā)動(dòng)機(jī)的輸出轉(zhuǎn)矩。 全套圖紙，加 153893706 關(guān)鍵詞 ： 壓盤 ； 膜片彈簧 ； 摩擦片 ；操縱機(jī)構(gòu)；離合器 II ABSTRACT Automobile clutch gearbox is located between the engine and flywheel shell, with screw assembly will be fixed in the clutch after the plane of the flywheel, clutch gearbox output shaft is the input shaft. In the car, the driver can be down or release the clutch pedal, so that the temporary separation of the engine and gearbox, and the gradual bonding to cut off or transfer the engine to the transmission input power. At present, widely used in all kinds of cars on friction clutch is a moving part of the friction between the subordinate to transfer power and can separate device. This design is mainly to the medium truckloads of diaphragm type spring clutch on the design. According to the using conditions and vehicle parameters of vehicles, according to clutch system design steps and requirements, the basic parameters of the first choice, second to parts design: pressure plate, clutch cover, elastic transmission piece, separation device, and driven plate, driven plate and platen hub, operation, reverse design of the spiral spring shock absorber. According to various spare parts working conditions, and analyses the relevant respectively. Ensure that the design of the clutch can utmost transfer engine torque.
