手动变速器的优点如下：•高效率•耐用和具有运动性自动变速器的优点如下：•舒适.•在换档时不会产生牵引力的中断出于上述原因，GIF准备将这两种变速器的优点集中到双离合器变速器中。
该设计使用两个“湿式”片式离合器，和不同的自动换档程序，使操作者达到高度舒适要求。
此外，它还能够直接施加影响，非常快速地、无冲击地切换档位，使手排档的驾驶员体验到驾驶的乐趣。
为此，在使用手动变速器时，要消耗燃料。

博格华纳：展示当下和未来内燃机、混动和纯电动需求的热管理、减排及驱动技术
图1 博格华纳展台图2 博格华纳的Vistronic@系列风扇离合器Vistronic@系列风扇离合器由发动机控制模块精准调控转通过发动机ECU传输PWM信号实现控制，闭环控制与电控环境兼容)，在提供更强劲散热能力的同时改善了燃油经济性，减少了无用功消耗。
具体而言，一是改善效率：风扇会在有需要时以合适的转速转动，油耗及功率损耗可降低约～10%；二是免维修：自有模块化整体更换，无需额外维修三是更加精准的温控策略：为延长发动机及零件寿命提供可能；四是采用高速储油腔和独有液体分布设计。
另据博格华纳介绍，Vistronic@系列风扇离合器覆盖813 mm的风扇直径，可用于在轻、中、重型商用车(与非道路)。
在连接上，可以曲轴直连，也可选择螺纹轴与法兰轴连接方案，并可选择正转或反转设计。
应用于混合动力汽车的内燃机EGR技术混合动力汽车是新能源汽车的重要技术路线之一，其中内燃机动力需要同步满足国家最新排放法规的要求，如当下的国图4 eTurbo TM电子涡轮增压器的工作原理图处理技术和精确的空燃比控制，捕集多余的废气能量，驱动电机发电，同时降低排放。
eTurbo TM在瞬态增压响应方面提升200%以上，同样稳态扭矩也得到很大提升，从而可进一步促进发动机小型化：在不损失性能的前提下，还带来了更低的燃油消耗及排放，尤其适合于米勒发动机的需求。
除了提升车辆性能以外，eTurbo TM还可以将多余的废气能量，直接转换为电能，可用作辅助电源，或者为电池充电，从而可以减少电池的容量。
eTurbo TM还可以根据需求，增加发动机背压，通过与废气再循环EGR的配合，来降低排放。
eTurbo TM的电气功能也可以关闭，关闭后即恢复为传统的涡轮增压器运转。
凭借eTurbo TM的关键性能和能效特性，博格华纳一直致力于持续提升车辆性能，也致力于协助整车厂在满足日趋严格的全球排放法规的同时提高燃油效率。
早在2019年1月，博格华纳就与欧洲OEM客户签订了供货合同，为其生产的乘用车提供高性能的电子涡轮增压器eTurbo TM，这是博格华纳赢得的eTurbo TM首份系列生产合同，并计划于2022年开始批量化生产。
博格华纳涡轮增压器的维护保养和故障诊断
博格华纳涡轮增压器的维护保养和故障诊断BorgWarner博格华纳是全球动力系统解决方案的领导者，专注于开发领先的动力系统方案以改善燃油经济性、降低废气排放和提升动力性能。
BorgWarner博格华纳于20世纪90年代收购了全球著名的涡轮增压器制造商——德国3K及美国Schwitzer/施威策公司，合并成为博格华纳涡轮增压系统，为乘用车(汽油机和柴油机)、商用车、工程机械、农用机械、船舶和发电机组等动力设备提供全球一流的涡轮增压技术。
BorgWarner博格华纳涡轮增压系统一直致力于涡轮增压技术的创新，并在此领域不断创造新的技术标准。
博格华纳涡轮增压系统拥有R2S®两级可调涡轮增压系统和电动增压系统、世界首台汽油机VTG可变截面涡轮增压系统、首台可承受1050℃的汽油机涡轮增压系统，钛合金压叶轮，高强度和高精度的铣削压叶轮以及气动和电子执行器等业内顶尖技术。
BorgWarner博格华纳R2S®两级可调涡轮增压系统相对于传统的单涡轮增压器，可以提供更好的燃油经济性和动力性能。
R2S®包含了两个相连的涡轮增压器，小型的高增压涡轮增压器用于提升发动机的瞬态响应性(即提升低速扭矩)，大型的低增压涡轮增压器确保较大转速范围内的高扭矩输出。
BorgWarner博格华纳VTG可变截面涡轮增压系统，可以根据发动机的工作状态，实时精确调整涡轮的形状，从而以最优异的燃油效率获得最佳的动力输出，对于提升低速扭矩具有显著的作用。
涡轮增压器工作原理在同等排量的情况下，相对于传统的自然吸气发动机，涡轮增压发动机可以获得更多的空气以支持更多的燃油充分燃烧，从而在获得更大功率的同时达到省油、环保的效果。
涡轮增压器的工作原理见图1。
发动机排出的高温废气进入涡轮增压器驱动涡轮转动，然后从涡轮排气出口排出。
转动的涡轮带动与其相连的压叶轮，压叶轮将更多经过空气滤清器的空气增压后送入中冷器和发动机气缸。
由于进入发动机气缸的空气经过了增压和冷却，这样在同样大小的气缸内可以得到更多的空气，燃烧更多的燃油，并且使燃烧更充分，从而使发动机产生更大的扭矩，降低了排放。
中英文文献翻译—双离合器变速箱
附 录A双离合器变速箱(Dual Clutch Transmission ，以下简称DCT)是当前发展最迅速的新型变速箱，它以传统手动变速箱为基础加入双离合器和电控组件，获得优异的性能表现和良好的燃油经济性。
已经成为继可变气门正时、可变气门升程、涡轮增压和缸内直喷之后的又一个技术亮点。
简单说来DCT 是两个传统手动变速箱的集合体(分别为奇数和偶数挡)，拥有两个离合器，两根输入轴，但仅有一根输出轴。
离合器的分离与接合，以及挡位切换都在电脑的掌控下通过液压机构进行控制，因此也能提供手动换挡模式。
动力传递效率高(意味着油耗低)、挡位切换迅速和成本低于传统自动变速箱是双离合器变速箱的三大优势，因此得到越来越广泛的应用。
双离合器变速箱由法国人Adolphe K égresse 在二战前发明，计划用于配备充满传奇色彩的雪铁龙Traction ，但当时的市场状况并不适合商业应用。
双离合器变速箱在等待了半个世纪后才开始配备民用车。
上世纪80年代初，保时捷自行研发了全球首台双离合器变速箱，利用电控系统将双离合器变速箱的结构变得足够紧凑，称为Doppelkupplungsgetriebe(德语，简称PDK)。
首款PDK 双离合器变速箱抢先配备956和962勒芒赛车，以及奥迪Sport Quattro S1拉力赛车，并获得不俗战绩。
并获得不俗战绩。
但赛场与市场毕竟存在不小的距离，但赛场与市场毕竟存在不小的距离，但赛场与市场毕竟存在不小的距离，双离合器又花费了双离合器又花费了二十年降低成本和提升耐用度才成功实现商用。
大众于2002年为高尔夫R32(第四代高尔夫，PQ34平台，2003款)配备DSG(Direct-Shift Gearbox)双离合器变速箱，这是双离合器变速箱首次配备量产车。
这是双离合器变速箱首次配备量产车。
与传统自动变速箱相比，与传统自动变速箱相比，与传统自动变速箱相比，大众的这台大众的这台DSG 省去了液力变矩器和行星齿轮组，取而代之的是湿式双离合器和简单的斜齿轮。

及工作原理，对润滑油提出了较 高的性能要求。新兴的DCTF产品
从上述要求来看，无论是 传统的自动变速器油（ATF） 还是标准的手动变速器液压油 （MTF），都无法承担保护DCT 的重任。为了保证DCT的技术优 势和使用耐久性，DCTF需要采用 特定的配方技术[1，2]，确保DCTF 具有优异的高低温性能、适宜的 摩擦特性和摩擦耐久性、良好的 极压、抗磨损特性、优异的热和 氧化稳定性、良好的防锈、防腐 蚀特性以及与橡胶、密封材料和 电子零部件的兼容性。

严重磨损等状况。因此，为了保证 离合器控制和液压控制系统的正常 运行，DCTF必须具有良好的抗泡性 能。同时，还要求DCTF具有防腐性 能，防止低温下铜、钢、铝材质的 液压元件的腐蚀。
启动和保障液压单元的工作。同时 DCTF在高温或在高载荷下仍能保护 变速箱部件。DCTF通常为具有较 好剪切稳定性的较低黏度油品，其 100 ℃运动黏度在7.0 mm2/s左右， 黏度指数在150以上。
离合器的润滑
湿式离合器无疑是DCT最重要 的关键部件，离合器的精准控制对 于变速箱的顺利操作极其重要。这 就要求DCTF必须在约2×106次换挡 的换油周期内保持一致的启动特性 和抗抖动耐久性。因此，DCTF必 须具备适宜的摩擦特性和摩擦耐久 性，以保证平滑、持续的换挡。

日前，菲亚特也正式宣布其自主研发的双离合变速系统将于2009年发布。
这套变速器被命名为C635，配备在菲亚特多款车型上，包括Grande Punto，Bravo和阿尔法罗密欧的一些车上。
将于2010年上市。
上汽自主品牌汽车——荣威将在2010年前推出与博格华纳合作的带DSG双离合器变速器的车型。
根据上汽的规划，09年就要上市的荣威750 1.8T和荣威W261最有可能成为搭载博格华纳DSG双离合器技术的车型。
总之，虽然大众等厂家各自推出了双离合器变速器，但是核心的双离合控制模块均来自美国博格华纳公司。
双离合器变速器的结构特点及工作过程图 3 大众汽车配备双离合器自动变速器的部分车型图4 其他车厂双离合器技术的车型结构特点双离合器变速器是由两个离合器集合而成的双离合装置、基于手动变速器的三轴式齿轮变速系统、自动换档机构、电子控制液压控制系统组成。
输入轴总成是由一个实心轴及其外部套筒轴组合而成的双传动输入系统，奇数档位和偶数档位的传动齿轮分别布置在这两个输入轴上（见图6所示）。
离合器1与实心输入轴相联，控制奇数档，离合器2与套筒（空心）输入轴相联，控制偶数档。
两个离合器轮流向双传动系统传递动力。
而动力的输出轴也是有分别的，一根输出轴实现低速档时的动力输出，另一根轴实现高速和倒车档的动力输出，两根输出轴的动力都要和变速器的最终输出轴联动在一起，将动力输送到车轮上，此外在变速齿轮组的布置上也没有采用传统的布置方式，变速齿轮的放置并不是按照档位的顺序排列的，这样相邻两个档位的变速齿轮就不会再共用一个同步器，这更是为实现动力的无缝传递提供了技术保证。

双离合器式自动变速器的七挡齿轮变速器设计-开题报告
1940 年，Darmstadt 大学教授 Rudolph Franke 第一个申请了双离合变速器专利，并在货车上进 行了装车试验，但始终没能投入批量生产。随后保时捷也发明了专用于赛车的双离合变速器。到了 20 世纪 90 年代，国内外各大汽车厂商都投入了较大力量对 DCT 进行研究和开发，并开发出了多 种型式的 DCT 产品。较为突出的是德国大众公司和美国博格华纳（BorgWarner）集团合作开发的 第一款能适用于大批量生产的双离合变速器—直接换挡变速器（Direct Shift Gearbox 简称 DSG）。 大众公司已将 DSG 应用于 Audi TT、第五代高尔夫等多种主流车型上。在大众汽车 DSG 一马当先 的带领下，其他国家厂商纷纷投入人力物力加入”双离合器变速器”的队伍。与大众不同的是，其他 厂商更专注于提高双离合器变速器所承受的最大扭矩，将双离合器变速器装备到跑车上。
正是这样的两个离合器配合换挡的结构，在挡位切换时齿轮早已衔接，DSG 双离合自动变速 器实现了，平顺换挡、快速换挡、动力“无间断”地输出，节约燃油的设计目的。据大众官方数据，
目前普及型的双离合变速器换挡时间只有 0.2 秒左右。即使是全球最好的赛手换挡速度也不可能与 双离合变速器相比。双离合变速器换挡时间也远超出人类操作的极限。
总之，双离合器自动变速器既继承了传统手动变速箱传动效率高、结构紧凑、重量轻、价格便 宜等许多优点，又实现了液力机械自动变速器和金属带式无级自动变速器动力换挡，换挡品质好的 优点，使车辆具有很好的动力性和燃油经济性，具有优异的性能和广阔的应用前景。

One example illus-trates our innovative capability: the Pressure Sensor Glow Plug PSG. BorgWarner Emissions Systems was the first manufacturer delivering this completely new glow plug technology for series vehicles, and the tech-nology is being installed in more and more vehicles. The sensor integrated in the heating rod of the glow plug measures the pressure in the combustion cham-ber and reports this to the engine control electronics. The optimized combustion ensures a lower level of emissions. BorgWarner’s Pressure Sensor Glow Plug has already won numerous innovation awards.Each of our divisions steadily pursues the goal of attaining and maintainingglobally leading positions.Dual coil ignition systemIgnition CoilsBorgWarner Emissions Systems is also one of Europe’s leading suppliers in the field of ignition tech n ology for gasoline engines. The ignition coil range covers every technology – from block ignition coils and distributor coils through to the latest plug shaft ignition coils and connector ignition coils. The latest development from the BorgWarner Emissions Systems engineers is the Dual Coil Ignition System in which each spark plug has not just one but two ignition coils, each working alternately. This doubles the number of charges and thus also the number of ignition sparks, while ignition delay is corre-spondingly reduced. If necessary a single spark can be extended to any length without dropout.Another product for the future is Ecoflash, the high frequency ignition system. Compared to conventional systems this patented technology generates an ex-tended corona discharge inside the combustion chamber - which means that even very lean fuel mixeswill ignite reliably.EcoFlash® High-Frequency Ignition SystemGlow Plugs, Pressure Sensor Glow Plug (PSG) and Glow Plug Control ModuleDiesel Coldstart TechnologyIgnition TechnologySignificant products in the Diesel Cold-Start T echnology sector:■ Instant Start Systems (ISS)■ Pressure Sensor Glow Plug (PSG)■ Ceramic Glow Plugs ■ Glow Plugs■ Glow Plug Control Module ■ Suction Intake Air Pre-HeatingSignificant products in the Ignition T echnology sector:■ Ignition Coils■ High-Frequency IgnitionIgnition Coils5Cabin HeatersAs a development partner in the automotive industry, the company is ideally positioned in the auxiliaryheater sector.

2021双离合器式自动变速器课件演示PPT优秀资料
概述
双离合器式自动变速器〔Dual Clutch Transmission〕简称：DCT。是基于双轴式 常啮齿轮，手动变速器Mt演变而成，保存了 构造简单、传动效率高的优点，并升华为电 控液动换档控制，改善了换档品质，降低了 油耗及故障率和制造本钱，它己在群众车系 和福特车系中成功的使用。又因继承性好， 降低了加工设备的投资，适合国情需要，前 景十分可观。
一、DCT系统的构造特点：
7. 变速手柄的档位排列方式，仍是：P、R、N、 D、S传统方式。有的车系还加装了手动换档 开关，在D档位时，手柄也可利用手动通道 上下微动，手动依次升档或降档行驶。
一、DCT系统的构造特点：
8. 两个不同尺寸的离合器，同轴心的套装在一起，以 一样的摩擦力矩Mc，交替传递发动机的转矩。 因离合器的最大摩擦力矩Mc为下式： Mc=ZPμRc 〔n.m〕 Z—摩擦面数；P—压盘上的油压作用力； μ—摩擦系数；Rc—摩擦片的平均摩擦半径。
驾驶员的体验是DCT很多优点的一个。少于8 毫秒的升档时间使很多人感觉到在市面上所 有的整车中装备DCT的能提供最价的动态加 速性。当然通过减少换档冲击，DCT也提供 了更为平顺的换档。
可能DCT最引人注目的优势是改善了燃油消耗。 由于换档过程中没有动力中断，燃油效率显 著提高。有数据说明6档DCT与传统5档自动 变速箱相比，燃油效率可增加10%.与无级变 速的CVT变速箱相比，DCT可以承受更高的 扭矩要求。
例如：
Golf-R32轿车性能参数比较表如下： 群众公司对Golf-R32分别装用手动变速器MT 与DCT自动变速器进展了性能比照试验，结 果证明：DCT式自动变速器，具有优良的燃 油经济性和动力性能。
