通过运用某些部件，传动系统可将发动机产生的动力传递到车轮驱动上。这些部件主要包括离合器、变速器、驱动轴、主减速器和差速器。变速器是一种速度和动力转换装置，通常安装在车辆的发动机和驱动轮之间，用来调整发动机转速与驱动轮转速间的比率关系，以适应各种行驶状况。变速器还可以调节发动机曲轴传递到螺（旋）桨轴的扭矩，实现倒车行驶，在停车或滑行时长时间中断发动机和动力转动系统间的连接。采用特殊变速器是为了满足不同扭矩的要求。根据向前传动比，变速器分为三挡、四挡和五挡。5.Transmission

Notes1.clutch：离合器。离合器位于发动机和变速箱之间的飞轮壳内。在汽车行驶过程中，驾驶员可根据需要踩下或松开离合器踏板，使发动机与变速箱暂时分离或逐渐接合，以切断或传递发动机向变速器输入的动力。2.rpm：rpm 是“revolutions per minute”的缩写，意为“每分钟转数”。Your site hereLOGO66.Steering System Menu Back Next Read the following passage and do the exercises.Your site hereLOGO6转向系统 转向系统为驾驶员提供了一种控制汽车行进方向的手段。转向系统包括方向盘、转向轴、转向器、转向横拉杆、前轴和转向节。依靠这些零部件的前后移动或转动，可以改变汽车运动的方向。转向器把方向盘的旋转运动转变为车辆的直线运动。大部分小型车都采用了齿条齿轮转向器。这套系统需要在传动轴下端尾部安装一个小齿轮。小齿轮与一些嵌在转向联动装置主要交叉部件下方的齿条相啮合。方向盘转动时，这个小齿轮也随之旋转。推动齿条向左或向右运动。这一运动又会通过连杆传递到前轮的转向节臂。Menu

system consist of?_3.What is the function of the steering gears?_The function of the steering system is to provide the driver with a means for controlling the direction of the vehicle as it moves.It consists of the steering wheel,steering shaft,steering gear,tie rod,front axle,and steering knuckle.The steering gears convert the rotary motion of the steering wheel into straight line motion.6.Steering System Your site hereLOGO6Menu Back Next B.Match the following English phrases with their Chinese versions.()1.steering wheel a.转向器()2.steering shaft b.前轴()3.steering knuckle

type of steering system which you are interested in,and try to talk about its principles and constructions.For Reference AnswerYour site hereLOGO There are basically two styles of vehicle steering systems,rack and pinion and worm gear box.Rack and pinion steering is one of the oldest types of steering systems and is still used today.Inside the rack body a flat rack gear moves in a linear direction,driven by a circular gear called a pinion.The steering wheel is connected to the pinion gear(shaft).A worm gear box style of steering system is constructed of two main parts much like the rack and pinion style system.The main part is called a worm gear;the other is a selector shaft gear.The worm gear is connected to the pitman arm and then to a center link and tie rod ends.The opposing end of the center link is supported by an idler arm,which is located on the opposite side of the frame from the steering box.Steering can be either power or manual.Power steering utilizes a hydraulic pump mounted on the engine,and driven with a multi rib belt.The fluid in the system is held under pressure until the wheel is turned,which releases the pressure and applies it to the steering system.9Menu Back Next 9.Surfing the Internet http:/ site hereLOGO10Back Next 10.Enjoying Yourself Menu A mechanic noticed his co-worker drinking brake fluid at lunch.“What are you doing,man?You cant drink that stuff!”“Relax,”replied his co-worker,“this stuff tastes pretty good,and I dont drink it all the time.”“Seriously,”the mechanic exclaimed,“that brake fluid is poisonous!”“Hey,man,”yelled the co-worker,“back off!I can stop any time I want.”Your site hereLOGOLOGOLOGOThank you!上海交通大学出版社上海交通大学出版社 Automobile EnglishAutomobile English
