【正文】 寸受限、采用單片式時摩擦扭矩不夠的場合。因此在 某 拖拉機(jī)離合器的設(shè)計過程中，選用摩擦式離合器。 6 具有良好的通風(fēng)散熱條件和必要的熱容量，以保證離合器工作溫度不以過高。直到離合器完全接合而停止打滑時，汽車速度方能與發(fā)動機(jī)轉(zhuǎn)速成正比。壓緊彈簧的壓緊力越大，則離合器所能傳遞的轉(zhuǎn)矩也越大。自動離合器有超越離合器、離心離合器和安全離合器等幾種。 離合器的 工作原理 離合器的主動部分和從動部分借接觸面間的摩擦作用，或是用液體作為傳動介質(zhì) (液力偶合器 )，或是用磁力傳動 (電磁離合器 )來傳遞轉(zhuǎn)矩，使兩者之間可以暫時分離，又可逐漸接合，在傳動過程中又允許兩部分相互轉(zhuǎn)動。 ： 汽車行駛過程中，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。 在 設(shè)計 離合器時首先應(yīng)根據(jù)車型的類別、使用要求等合理選擇離合器型式，并合理選 擇儲備系數(shù)、壓緊力、摩擦片尺寸等主要參數(shù)的具體值。 關(guān)鍵詞 : 拖拉機(jī) 離合器 儲備系數(shù) 壓緊力 摩擦片尺寸 黃河水利職業(yè)技術(shù)學(xué)院 3 Abstract In order to increase the level of agricultural mechanization in farming, to accelerate the pace of agricultural modernization, according to the existing clutch of a tractor and use of the performance of the work to plete the design of the clutch of a tractor. Through the design of the clutch, so that more excellent performance vehicle. When the first clutch in the design should be based on the type of model, requirements for a reasonable choice to use the clutch type, and a reasonable choice reserve coefficient, paction, and friction, such as chip size of the specific value of the main parameters. Checked after the clutch (mainly for wear, sliding wear and heat checking Gong) and the main parts of the strength calculation, and the pletion of the assembly drawing and mapping a number of parts. To achieve good use of the clutch and the structure of technology.
