福伊特液力缓速器技术介绍福伊特液力缓速器的由来福伊特公司自1870年开始从事流体动力学研究。1961年,福伊特第1台液力缓速器成功的用于行驶在美国洛杉矶山脉、重达1万t、以2206kw柴油机为动力的火车上,在坡度为3%长达数千米的坡路上穿山越岭,几乎无磨损的安全运行。赛特拉(SETRA)豪华客车的创始人奥托·凯斯鲍尔得知这一消息后,立即要求福伊特(Voith)公司为其客车开发缓速器,并于1968年开发出用于大客车的液力缓速器。从那时开始,福伊特对无磨损缓速技术以及相关领域进行了持之以恒的研究和广泛深入的试验,不断改进和创新推出新产品,并与世界上众多汽车制造商合作,精益求精,满足用户需求。至2009年,已生产液力缓速器达60万台,深受用户欢迎。福伊特液力缓速器的特点和功效1.安装使用福伊特液力缓速器能提高运营效率,降低成本,确保行驶更加安全汽车的安全性一直以来都很重要,特别是在汽车运输业蓬勃发展的今天,要求车辆有更高的运营效率,因此车载质量增加,车速提高,车辆行驶的动能成指数曲线增加,车速从40km/h提高到80km/h,车辆动能增加4倍。行车制动器的制动能力由于受多种因素的限制不能同步提高,下长坡长时间持续制动和高速制动时,制动器遭受巨大动能转变成热能的强负荷,制动衬片和制动鼓的温度可高达1000massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further ℃。在这样高的温度下,不仅制动能力下降,而且制动鼓极易龟裂,制动衬片严重磨损或烧损。致使制动器寿命降低,早期损坏,增加维修成本,甚至威胁行车安全。先进的盘式制动器质量轻,性能好,维修费用低,但由于摩擦面积小,遭受制动时巨大动能产生的热负荷使其表面的温度比鼓式制动器还要高,磨损严重,同样不能满足坡路持续制动和高速强力制动的要求;而液力缓速器吸收制动能量最高能够达到90%,可以保持车辆以高的平均车速行驶,有效的辅助行车制动器,从而提高车辆的运营效率,降低维修成本,使行驶更安全。实践证明,液力缓速器具有令人满意的效果,因此成为高等级商用车辆的首选。1.福伊特液力缓速器的特点⑴铝合金壳体,结构紧凑,质量轻,单位质量缓速力矩可达50Nm/kg。⑵缓速力矩范围宽,可在2000~4000Nm范围内选择,R120-3型最大缓速力矩可达2000Nm,R133-2型可达4000Nm。⑶液力缓速器与发动机缓速联合工作,可以获得最佳的缓速组合。⑷由于液力缓速器自身有自己的供油系统,可以在最短的时间内使大量的车辆动能转变为热能,通过发动机的冷却系统散掉,不仅没有过热问题,而且还可以在车辆下长坡过程中保持发动机的热状态,既节省燃料又保护发动机。⑸液力缓速器利用发动机的冷却系统散热。工作时,发动机处于怠速工况,温度一般不会超过140℃,缓速力矩不会随温度升高而下降,保持稳定的缓速能力,是真正的持续制动装置,无论是下长坡、在盘山公路上、在城市走走停停的行驶中,缓速产生的热量都能通过自身的热交换器和发动机冷却系统散掉,不会对周围的部件产生热影响,因此安装液力缓速器时不需要任何隔热措施,也不会增加发动机的热负荷。⑹液力缓速器在换挡的瞬间,仍保持缓速作用,缓速作用是连续的,这又提高了行驶的安全性。⑺在ABS将要起作用时,缓速器会自动退出运行。⑻因为安装了缓速器,会保证行车制动经常处于有效状态,行车更放心,可以以较高的平均速度行驶,更加安全、高效。⑼理论上,液力缓速器能吸收90%的车辆制动时的动能,通常可以延长制动衬片的寿命6~8倍或更长。福伊特液力缓速器的产品系列目前福伊特液力缓速器的产品根据安装方式分2大类:一类是串联安装在驱动线中massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further 1.主要产品有R120-3型和R133-2型;另一类是并联安装在驱动线中,缓速器与变速器组装或一体,通过中间齿轮实现动力连接,主要产品有Go/R115E,R115与沃尔沃变速器配套的VR3250,与戴姆勒—克莱斯勒变速器配套的R115H,与Eaton变速器配套的115H。福伊特R120-3型缓速器是一种适用于中型客车和货车的理想的缓速器,比如轿车运载车、单厢货车、饮料运输车、大件货物运输车、中型客车等。福伊特R133-2型缓速器是适用于旅游客车、重型货车及其他特种车辆的功率最大的缓速器,其主要特点是质量轻,缓速力矩大。R115H型缓速器是一种高转速比的缓速器,随不同的齿轮速比其转速最高时比传动轴的转速高一倍。R115型缓速器体积极紧凑,而且其缓速力矩在低转速时也相当高(比如在传动轴的转速为500r/min时,缓速力距为2000Nm)。如同所有其他福伊特缓速器一样,它拥有与变速器独立的供油系统。R115H型缓速器与变速器的组合将不会影响到紧急转向助力泵、转速表齿轮和传动轴的装配,也不需作任何的改动。表1福伊特系列产品主要技术参数技术数据R120-3/R120SR133-2R115H作用于传动轴上的最大缓速力矩/Nm200040003200缓速器最大转速/(r/min)3000/480028005000缓速挡位数(包括恒速级)555设备质量(包括法兰、热交换器,不包括机油)/kg658563单位质量缓速力矩(比值:304750massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further 缓速力矩/机器质量)包括机油/(Nm/kg)福伊特液力缓速器的工作原理和结构1.能量原理液力缓速器基于能量转换原理,与其他的制动方式一样,都是将车辆的动能转变为热能,然后散到大气中。车辆下坡时具有的动能为W动能,则W动能=mgL(G-f)或1/2mV2,mgH其中:m—车辆质量,kgg—重力加速度,m/s2V—平均车速,km/hH—坡道高度,mG—坡度,%f—滚动阻力系数L—行驶距离,m制动器或缓速器单独工作时,就是要将车辆的动能转换成热能散掉,保持制动或缓速的能力。图6为行车制动器、电磁缓速器、液力缓速器的不同散热过程。对于液力缓速器来说,只要冷却系统有足够的散热能力,其缓速能力则是无限的,液力缓速器通过发动机冷却系统散热(图7)。由于液力缓速器和发动机不同时工作,因此,在正常情况下,不会增加发动机的热负荷。下长坡后可以立即停车、驻车。显然液力缓速器的散热更为有效,因而成为缓速能力最稳定的缓速器。2.福伊特液力缓速器的结构原理以并联安装的Go/R115E缓速器为例来说明液力缓速器的基本结构和工作过程。115E型液力缓速器,由转子、定子、输入轴、齿轮副、热交换器、油槽(独立供应系统)等组成,见图8。缓速器经螺栓与变速器联接成一个整体,传动轴转动时驱动齿轮副使输入轴转动,输入轴通过花键与转子连接。当要进行缓速时,控制系统将油槽中的介质(机油)massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further 泵入定子和转子之间的工作腔,油对转子产生阻力,使传动轴转速慢下来,随着传动轴转速下降,车速也慢下来,产生缓速作用;当解除缓速作用时,控制系统将油释放至油槽,在结构上保证工作腔无油时也不会有阻尼,保证缓速器不会在车辆行驶时产生阻力多消耗燃料。由于工作液在运动中使进出口形成压力差,促使介质循环,流经热交换器时,车辆动能转变成的热量被来自发动机冷却系统的冷却水带走而散掉。缓速力矩的大小取决于工作腔内介质(机油)的压力和数量,以及传动轴的转速。油槽中的介质由比例阀控制的压缩空气压入工作腔,压缩空气的压力不同供入工作腔的介质量也不同,从而产生缓速力矩也不同,图9为介质充满系数f变化时缓速力矩变化的曲线图。f=1时,产生最大缓速力矩,n为传动轴转速,nN为缓速器的额定转速,M对应传动轴转速下的缓速力矩,MN为缓速器相应额定缓速力矩;f=0时为空挡,工作腔中无介质,无缓速力矩;f=0.25,0.50,0.75,1,将缓速强度由小到大分为4级,当压缩空气压力恒定时,将产生恒定的缓速力矩,实现车辆在坡路上的恒速行驶(图中用点划线表示)。福伊特液力缓速器的特性1.液力缓速器的特性4种常用的液力缓速器的特性曲线见图10。缓速力矩随传动轴转速变化,也随进油压力和进油量而变化。图10是当f=1.0时缓速力矩随传动轴变化的特性曲线。这些液力缓速器在800~2500r/min传动轴转速时都有很高的缓速力矩。车辆的制动系统应设计为行车制动器、缓速器、发动机缓速联合工作的系统,并使经常性制动的绝大部分能量由缓速器吸收,制动减速度变化在0.3g以下时,车辆动能的90%由缓速器吸收,仅有少量的能量由行车制动吸收。操纵机构设计还要保证在紧急情况下行车制动器和缓速器同时工作。2.液力缓速器与发动机缓速的联合工作液力缓速器与发动机缓速联合工作,可以得到最佳的缓速组合(图11)。发动机缓速低速时有良好的减速能力,转速上升时,液力缓速器缓速能力强,二者联合工作能够产生最佳效果。3.液力缓速器的性能要求福伊特液力缓速器的性能符合ECE-R13法规II类车辆(>12t的载货车)和IIa类车辆(>5t和超过8座的长途客车)的检测要求。根据能量转换原理,以规定的方法(路试或台试)在不超过规定的时间(12min)内,吸收并散掉在规定距离(6km)、规定坡度(IIa类车辆7%)以30km/h的车速下坡车辆所具有的等效能量Waiss,表2为规定的数值,公式1用于II类车辆,公式massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further

与变速器贴附安装是通过一个安装架贴附在变速器的输出端,见图4左上图,缓速器一端通过花键毂与变速器第二轴连接,另一端通过连接法兰与传动轴连接。液力缓速器、变速器和传动轴在同一轴线上,缓速器占有一段轴向尺寸,因此需要改变传动轴的长度。液力缓速器质量轻,一般不需加中间支撑。②独立安装缓速器不紧贴变速器安装,二者经中间轴连接,图4左下图,但缓速器、变速器、传动轴三者仍在同一轴线上,缓速器仍旧占有轴向尺寸,因此,也需要改变传动轴的长度,还需要增加中间支撑。2.操作福伊特液力缓速器(图12)主要由缓速器本体、电控装置(电子控制单元)、操纵装置以及诊断电脑(非车载)等部分组成。缓速器的操纵装置可以装置在转向柱管上也可以装置成与行车制动踏板联动,最终怎样装置由用户、整车制造商和福伊特公司协商确定。操纵装置操作手柄有6个位置,即0,1,2,3,4,5。,如图13所示。0位是缓速作用解除无缓速作用;1位是恒速级,控制车辆恒速下坡;2,3,4,5位将缓速能力分为4级,即25%,50%,75%,100%,缓速能力依次增加,第5位最高。最高的技术效果是什么呢?⑴下坡时的操作(图14)下坡时使用恒速级,下坡时用缓速器和行车制动调节车速至所要保持的车速,例如30km/h,车速到达30km/h时,拨缓速操作手柄至1位,车辆会恒定在该车速下坡行驶。若车速快起来,利用车制动辅助缓速器使车速降至恒定车速。电控装置具有记忆功能,操作手柄拨至1位(恒速级)时的速度会被记忆,当操作手柄拨离1位后,记忆会删除,因此,进入平路,操作手柄拨至0位,记忆将被删除。操作手柄在1位时,再拨至其他位置不能增加缓速作用。下坡时除了选择恒速级外,还可以先换入低挡,逐级拨下操作手柄,调节车速。有预见使车辆减速之前,最好先换入低挡,然后在运用缓速器,这样效果更好。⑵平路上行驶时的操作(图15)平路上行驶除紧急制动外可以利用缓速器调节车速,保持车距。在要停车之前利用缓速器减速,当车辆将停时在利用行车制动停车。massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further ⑶危险路面上行驶时的操作(图16)冰雪路面、连续转弯、泥泞路面等均被视为紧急减速可能会出现危险的路面。在这种路面上要慎用缓速器,要小心逐级的操作,不可迅速拨至高位。对于没有ABS的车辆在这种危险路面上不要运用缓速器;对于有ABS的车辆,缓速器在ABS激活前会自动断开。â福伊特水介质缓速器福伊特水介质缓速器(VoithAquatarder)体积小,质量轻,安装在发动机上,用水作介质,与发动机的冷却系统共用同一介质,从而省去油—水的热交换过程,也就省去了热交换器。水介质缓速器主要由壳体、转子、定子、水泵等组成,如图17和图18所示,水路系统见图19。新产品—水介质缓速器简化了散热过程,油介质缓速器和水介质缓速器散热过程的比较见图20。图10缓速力矩范围图11液力缓速器与发动机缓速的联合工作图12福伊特液力缓速器系统图13液力缓速器操作手柄与指示灯图14下坡时利用恒速级的操作图15平路行驶时缓速器的操作massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further

··福伊特voith·●缓速器迈进卡车领域的节点·  目前,我国卡车行业运营状态显得有些浮躁,相当大比例的卡车主采取一种“短平快”的方式运作。即投入较低成本买一辆车,连续高强度工作,不求车辆长期服役,要求短期内尽快回本。彭总对记者说,“这就像让你向一个不开会的人推销西装一样难,他没有需求,任何营销手段都无法奏效。”·  对于大多数卡车用户来说,缓速器应该属于高端零部件。不管从实际需求还是消费意识上讲,要他们接受缓速器都不是一件轻而易举的事情。像福伊特这样的高端零部件企业看重的潜在用户是注重产品全生命周期投资回报率的消费者,他们的消费往往更加理性。·彭总告诉记者,他就曾经遇到这样一位有心人。一位开了三十几年卡车的老司机,阅车无数,对卡车各个零部件非常熟悉,这位经验丰富的司机深知开车安全第一,曾主动找到福伊特要买缓速器,并且给技术人员开出了详细的配置单,他甚至比技术人员更清楚哪些配件搭配在一起才能发挥各自最大的作用。彭总带着一丝钦佩地说:“这样的有心人实在太少了,所以我们要做的工作还有很多。”·● 做我们该做的事·  价格昂贵一直是缓速器不被卡车用户接受的一大因素,据彭总介绍,福伊特为了让缓速器更顺利地进入卡车市场,目前定价为两万左右,相对客车来说降低了40%--50%,几乎是“卖一台亏一台”。福伊特把前期的亏本当做一种投资,只有客户在实际操作中体会到缓速器的优势,经过口口相传,缓速器才能逐渐得以推广。·  此外,福伊特已经在与东风、陕汽、福田等整车企业进行接洽,研发试验车,在各种环境下测试产品的性能。彭总表示,时机成熟,福伊特也会考虑选择一位卡车用户免费安装缓速器进行跟踪测试,以此来不断改进、完善产品。massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further ·● 未来的五年规划·  谈起未来,彭总显得十分乐观,对于缓速器的市场前景,他非常有信心。彭总对记者说:“路况险要的地方,刹车系统是否优秀非常重要,而高速公路也会有急弯和陡坡,因此不管是山路还是高速公路,都需要缓速器来辅助制动,确保驾驶员的生命安全。所以我相信缓速器的市场是好的,我们对此十分乐观。”·  未来五年,福伊特给自己制订了详尽周密的规划,比如与整车企业技术人员沟通,进行安装对接、线路优化、工人优化、底盘集成优化、产品匹配优化;配套发动机、大梁、桥如何选取;做相关实验,检测车辆是否有漏油、漏水现象,气压是否达到标准,电路设计是否合理等。此外,福伊特还预计进行新产品的研发,来不断满足市场及用户的需求。尽管缓速器在卡车领域的推广现状不尽如人意,然而福伊特却似一位乐观的开拓者,正以饱满的热情迎接每一天。··福伊特驱动技术系统(上海)有限公司·上海市上海市辖区沪闵路3986号·电话:021-54421550邮编:201108公司网站:http://www.voith.comhttp://www.shanghai.voithturbo.com联系人:人事部电话:(021)24087688传真:(021)64428610地址:上海市闵行区莘庄工业区华锦路265号(靠近元电路)可乘坐徐闵线、轻轨五号线在颛桥。然后打车到公司。或者乘坐颛元线到元江路站massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingcadres;Keepagainstallformsofillegalandcriminalactivitiesofhighhanded,ensureagoodsocialorder;Strengthenthecollectionofintelligenceanalysis,closelyguardedactivitiesofevilcults;Fullimplementationofthesocialsecuritypreventionandcontrolinkeyareasandthetreatmentofseriouspublicsecurityissuestotroubleshoot,ensuringharmonyandstability.Fourfurtherstrengthenpublicityandideologicalwork.Typicalhighlightsofselectedtreecultivation,andmoralexemplarsintheprovincedonothaveemerged,respectingthemoralmodelHangLiPoh,theprovincialworkerYuYoubo,State-levelmodelworkerFanYouzhi,HuJingqiu,includingYunnan,nujiang'sfinest,promotedthetheme,thecombinationofapositiveenergy.HunansatelliteTVinwangjiduVillagecompletedthemetamorphosisoftheshow'sfilming,silentnunutelevisionprogramairedthe"busybody"LaoLi,ancientvillage,woodandJiacunandXXmvillageswereratedasprovincialandStatelevelcivilizedvillage.XXinternationalvisibilityandreputationfurtherenhanced.Inaddition,wecontinuetopromotedemocracy,people'scongresses,politicalconsultativeconferenceroleplay,gongqingfu,amassorganizationtobetterservethescientificdevelopment.Further
