太原理工大学现代科技学院论文-I-摩擦片式自锁差速器设计摘要普通差速器以无法满足人们的需求，越来越多的汽车加装了摩擦片式，设计一种摩擦片式差速器，它是利用摩擦元件相对转动所产生的摩擦力矩来实现左右半轴转矩的重新分配，从而达到防滑的目的，其防滑反应迅速。针对重庆长安SC1010车型进行设计，为其新增设压力环，使得产生的摩擦片式摩擦力矩会随传递转矩的增大而增大，并在压力环上开设v型槽，与行星齿轮轴端部的v型斜面相配合，用来实现对摩擦元件的压紧，提高了差速器使用寿命；在摩擦元件和差速器壳之间采用碟形弹簧作为常作用弹性元件，这是由于其轴向尺寸小，具有良好的弹性变性的特性。在满足锁紧系数的情况下具有结构尺寸较小，零件数量少，易于实现电控，给厂家的制造和后续开发提供了方便。关键词汽车；摩擦片式；差速器太原理工大学现代科技学院论文-II-RectangularCoordinateHydraulicControlDesignoftheManipulatorAbstractOrdinarydifferentialcannotsatisfythepeople'sdemand,moreandmorecarsaddedfrictiondisc,africtionplatetypedifferentialdesign,itisredistributionofthefrictionmomentfrictionelementusingarelativerotationisgeneratedtoachieveabouthalfshafttorque,slipsoastoachievethepurpose,theslipresponsequickly.ForChongqingChanganSC1010modelsfordesignandthenewpressurering,sothatitincreaseswiththeincreaseoftorquetransmissionfrictiondiscfrictiontorque,andopeningofVgrooveonthepressurering,andplanetarygearshaftendVtypeinclinedsurfaceswith,torealizethecompressionoffrictionalelementandimprovethedifferentialservicelife;inbetweenthefrictionelementandthedifferentialcasethedishspringasoftentheroleofelasticelement.Thisisduetotheaxialsizeissmall,withthecharacteristicsofgoodelasticdeformation.Inthecaseofmeetingthelockingcoefficient,thestructurehastheadvantagesofsmallsize,fewparts,easytorealizeelectroniccontrol,andconvenientmanufactureandsubsequentdevelopment.KeywordsAutomobile;Frictionplate;Differentialmechanism太原理工大学现代科技学院论文-III-目录摘要...........................................................................................................................IAbstract......................................................................................................................II第1章绪论................................................................................................................11.1设计的目的和意义...........................................................................................11.2差速器研究现状...............................................................................................11.3摩擦片式的发展现状.......................................................................................21.4摩擦片式的研究发展.......................................................................................31.4.1转矩感应式摩擦片式................................................................................31.4.2转速感应式摩擦片式................................................................................31.4.3主动控制式摩擦片式................................................................................31.5本文的原始数据...............................................................................................3第2章差速器的设计要求及选型分析....................................................................52.1差速器的分类和原理.......................................................................................52.1.1差速器的分类............................................................................................52.2差速器设计要求...............................................................................................62.2.1差速器理论设计计算主要技术指标........................................................62.2.2差速器实际生产加工主要技术指标........................................................7第3章主要零部件分析..........................................................................................113.1压力环.............................................................................................................113.2摩擦元件.........................................................................................................123.3蝶形弹簧.........................................................................................................143.4行星齿轮轴.....................................................................................................163.5行星齿轮与半轴齿轮.....................................................................................173.64.6差速器壳................................................................................................173.7锁紧系数及其计算.........................................................................................18第4章摩擦片式差速器设计计算..........................................................................204.1摩擦片当量摩擦半径和预紧力矩的分析计算.............................................204.1.1摩擦片当量摩擦半径的分析计算..........................................................204.1.2预紧力矩...............................................................................................214.2确定摩擦元件结构参数.................................................................................21太原理工大学现代科技学院论文-IV-4.2.1摩擦元件内外径......................................................................................214.2.2单侧摩擦元件的摩擦面数......................................................................214.2.3摩擦元件厚度..........................................................................................214.2.4摩擦元件材料..........................................................................................224.3确定压力环v型槽楔角和压力环作用当量半径.......................................224.4确定碟型弹簧的结构参数.......................................
