Its function is causes between the engine and the transmission gearbox can join gradually, thus guaranteed that the automobile starts steadily; shuts off between the engine and transmission gearbox's relation temporarily, is advantageous shifts gears and reduces shifts gears the time impact; When automobile emergency brake can play the separation role, prevents transmission systems and so on transmission gearbox to overload, plays certain protective function. Therefore, any form's automobile has the engaging and disengaging gear, is only the from is different. The structure of the clutch is reasonable or not, whether the performance matching to the total vehicle, is directly related to the automotive ease of use, vehicle dynamics and the economics and the economy. This paper studies the clutch and matching to the vehicle design. Specific content of the following aspects of the paper on the following main areas of research: According to the design requirements of the automobile to complete the total design, and chose the structure type and the structure type and the main parameters of the vehicle. Compared to the structure of the Clutch, and chose the construction form of the clutch. Under the previous car design, made a choice to the basic clutch size parameters. Made right clutch parts for the clutch parte selection, design and calculation of matching. A clutch control system design. Through to the mechanical type control system and the hydraulic pressure type control system characteristic's, and has selected the hydraulic pressure type control system, has carried on the design and the size computation t it Key words: Clutch, Spiral Spring ,Matching 目 錄 第一章 前言.............................................1 第二章 離合器主要參數的選擇.............................3 §2.1 離合器的靜摩擦力矩.............................3 §2.2 離合器的靜摩擦力矩與發(fā)動機最大轉矩的基本性能關.4 §2.3 離合器基本結構尺寸和參數的選擇 ................4 §2.3.1 離合器后備系數的確定........................ 5 §2.3.2 摩擦系數的確定..............。.............. .6 §2.3.3 摩擦片半徑的確定............................6 §2.3.4單位壓力的確定........................... ... 8 第三章 離合器的結構設計與計算..........................11 §3.1 從動盤總成....................................11 §3.2 從動盤總成設計................................12 §3.2.1 從動盤鋼片................................12 §3.2.2 從動盤轂...................................15 §3.2.3 從動盤摩擦片...............................19 §3.3 壓盤和離合器蓋................................20 §3.3.1 壓盤設計....................................20 §3.3.2 壓盤傳力機構的設計..........................22 §3.4 離合器蓋的設計................................23 §3.5 圓柱螺旋彈簧的設計............................26 §3.6 扭轉減振器的設計..............................27 第四章 操縱機構的設計計算.............................30 §4.1 離合器操縱機構的基本要求與常用結構類型........30 §4.1.1 對離合器操縱機構的基本要求...................30 §4.1.2 常用離合器操縱機構的類型......................30 §4.2 離合器操縱機構主要的參數的確定與設計..........34 第五章 傳動軸的設計與計算.............................36 第六章 結論.....................................39 參考文獻...............................................40 致謝...................................................41 外文資料譯文...........................................42 V
