The suspension covers the arrangement used to connect the wheels to the body.悬架是车架(车身)与车轮(车桥)之间一切连接传力装置的总称。其目的是防止车轮遇到路面不平产生的巨大冲击传给车内的货物和乘客;否则会产生不舒适的感觉和货物的损坏。
The purpose is to prevent large shocks,caused by the wheels striking bumps in the road, being passed to the vehicle occupants and components;otherwise discomfort and damage would occur.

Poor alignment can make a car pull to one side and stop the front wheels from returning to the straight-ahead position after a turn.
不正确的车轮定位参数会使汽车产生偏驶,阻止车轮在转向后回到直线行驶位置。

Leaf springs are made of long, flat pieces of metal clamped together to form a spring. The spring not only acts as a spring but also locates the axle.
To overcome weakness at the mid-point of the main leaf, either the leaf is made thicker at the center or a series of leaves is used. Each leaf is shorter than the one directly above it.
钢板弹簧由许多长平的金属片夹在一起形成.钢板弹簧起到弹簧的作用,而且也装在车轴的位置。为克服主片中部强度不够的缺点,可以把其中部加厚,或者采用多片簧片。每个钢板比它上面的那个短。

Torsion bar 扭杆弹簧
Torsion bar 扭杆弹簧Torsion bar 扭杆A n ch o r en d
扭杆弹簧通常一端固定在汽车上的适当位置,另一端安装在摇臂上.冲击力作用在摇臂的一端使它弯曲,这引起扭杆扭曲来吸收冲击力.冲击力消失时扭杆扭曲消失,摇臂回到原来的位置.
Torsion bars normally connect to the car so that one end is fixed in place and the other attaches to a lever arm . When a force acts on the end of this lever arm, it bends up, causing the torsion bar to twist and absorb the force.When the force is
released, the bar untwists to force the lever back to its original position.
When a spring is compressed and
then released it will oscillate for a
period of time before coming to rest.
Applied to a vehicle this action will
cause a most uncomfortable ride.
The purpose of a shock absorber is
to absorb the energy stored in the
spring and so reduce the time that
the vehicle is bouncing.

第13章汽车制造 13.1 车辆结构的设计与制造 为了有效而经济地适应不同的汽车生产批量,汽车工业采用各种各样的制造工艺。为了研究出成本最低的生产方案,必须将工具的投资与给定批量的可变的成本相平衡。对于批量很小的生产,减小投资非常重要。通常,这种情况会出现在年产量不足千辆的专用车行业。在这种情况下,为了减小工具与设备的投资,可允许采用更贵的材料和长的生产周期。对于中等批量的生产(约25000件/年),重要的前提是实现自动化。对于大批量生产(例如汽车,对六年生产周期的总产量为数百万辆),固定成本被分摊到所生产的几百万辆汽车上。因此,减小可变成本非常关键,采用较低成本的材料和快速的生产周期对产品的成功至关重要。 这样,利用可变成本来管理工具与设备的投资的需要对车身的设计方式产生了重要的影响。为此,出现了若干种汽车车身结构设计,其中包括非承载式(车身在车架上)、单壳体式结构、空间构架和整体式车身设计。车身设计的原始方法(将车身放在车架上)今天还广泛应用于货车上。这种方法非常适合于大批量生产,因为它基本上属于一个将车身结构件连接到(但却独立于)底盘的系统。 在单壳体式结构中,车身结构通过挤压件和比较简单的冲压件即压制成形件来制造。这就形成了一种非常简单,具有连接底盘、前端件和覆盖板件的连接点的“浴盆”形结构。由于这种方法减少了冲压件和铸件的数量,因此也就减少了成形和铸造使用的昂贵的模具和铸型。所以说,单壳体式车身结构是一种投资最低的车身设计方法。 在空间构架设计方法中,车架元件一般用挤压法来制造。这些挤压件通常用铸件(叫做“节点”)连接在一起。这样,这种车架就可用于承受载荷并为外车身板件提供连接点(图13-1)。这种车身设计方法最适合于小批量到中等批量的汽车生产。 在整体式车身设计中,车身主要是由连接在一起的冲压件构成,这样,车身和底盘被整合成了一个结构件(图13-2)。今天这种方法已经成为制造大批量生产的汽车的一种普通方法。在整体式车身设计方法中,通常,通过将两个独立的冲压件拼合成箱式断面结构,来获取要求的刚度和强度。最近几年,越来越多地采用液压成形管材来替代某些冲压和焊接薄壁断面结构。 图13-1 奥迪A2铝空间构架白车身

UNIT TWO P18 An automobile probably has about 7,000 different parts in it. Some of them make it more comfortable or better looking, but most of them are to make it run. 一台车可能有7000多个不同的零件。一些使它更舒适或外观更好看。但大部分是使它能运转的。 The three basic components of the automobile are the engine, chassis and body. 汽车基本三大组成部分是发动机,底盘和车身. The engine converts the fuel energy into mechanical power. An internal combustion engine powers our modern automobile. The engine burns its fuel within the engine proper, as compared to a steam engine where the fuel is burned externally. The gasoline and air mixture of the internal combustion engine is compressed by a piston inside an airtight cylinder and ignited by a spark. The trapped air-fuel mixture burns fiercely, causing tremendous heat which expands the trapped gases and pushes the piston down. This is the motive power of the automobile. The automobile engine is essentially a heat engine. It requires fuel to burn, a spark to ignite, lubrication to minimize friction, and a cooling system to dissipate unwanted heat. 发动机把燃油的能量转化成机械能.内燃机给现代的汽车提供动力。发动机在其内部燃烧油料,相比蒸汽机是在外部燃烧燃料。内燃机汽油和空气的混合物通过密封汽缸内的活塞压缩,由火花塞点燃。被密封的空气燃料混合物剧烈燃烧,产生很高的热量,使压缩气体膨胀并推动活塞下降。这就是汽车的原动力。汽车发动机实质上是个热能发动机。它需要燃料燃烧,火花塞点燃,润滑剂减小摩擦,还要有冷却系统来驱散多余的热量。 The fuel system takes a correctly proportioned mixture of gasoline and air to burn and develop the power needed to push the piston down the cylinder. To store, mix, and deliver this air-fuel mixture is the duty of the fuel system. 燃油系统吸取适量比例的汽油空气混合物进行燃烧并传递能量,推动汽缸向下运动.储存,混合和传递空气燃油混合物是燃油系统的工作. When the explosive mixture of air and gasoline is compressed tightly, a spark is sent through the mixture, setting it on fire, which results in the heat and expansion used to push the piston down the cylinder. The ignition system furnishes a spark to each spark plug when its cylinder is full of the compressed air-fuel mixture. 当空气和汽油的爆炸性混合物被压紧,火花塞通过混合物,点燃气体。产生的热量和膨胀力推动活塞在汽缸内下降。当其内部充满空气燃油混合物时,燃油系统给每个火花塞提供火星. The lubrication system provides a constant flow of filtered oil to all moving parts of the engine. The system consists of an oil pan to store the oil, a pump to circulate it, a filter to remove solid abrasive particles, and an oil gauge or light in the driver’s compartment for checking purposes. 润滑系统连续不断地给发动机所有运动部件提供过滤油脂.此系统包括储存油的油底壳,循环油的油泵,带走固体腐蚀颗粒的过滤器,以及在司机舱内用于测量的油压表或灯. The engine derives its power from burning fuel. Unfortunately, not all of this heat can be used, and, if allowed to remain in the engine, it would soon destroy it. The temperature of the burning air/fuel mixture About 4500°F. Compare this with the boiling point of water, 212°F, and the melting point of iron, 2500°F. If this unused heat were not removed, the engine would soon melt. 发动机的动力来自燃烧的燃油,然而不是所有的热量都被使用,而且如果让这些热量留在发动机内,它会很快损毁发动机的。空气燃料混合物燃烧时温度达到约4500°F.与水的沸点212°F和钢铁的熔点2500°F相比,如果这些剩余的热量不被带走的话,发动机会很快熔化的.

汽车专业英语语言特点及翻译方法分析 目前汽车专业英语的教学已经成为高职高专汽车工程学院各个专业的一门专业基础课,它的重要性也随着经济的发展而日益凸显。本文主要对汽车专业英语的语言特点和翻译方法进行了分析。 标签:汽车专业英语语言特点翻译方法 1 汽车专业英语词汇特点 1.1 技术词汇汽车专业英语主要用来介绍现代汽车,有其专门的词汇和术语,其专业性很强。例如:crankcase(曲轴箱),camshaft(凸轮轴),detonation (爆震),turbocharger(涡轮增压器)等。 1.2 次技术词汇这类词在各专业中出现的频率较高,在不同的专业中具有不同的含义,应联系上下文来确定它们的确切含义。例如:在基础英语中eye意思是“眼睛”,在专业英语中可以根据不同场合分别表示“孔”、“环”、“镜”、“圈”、“窗”、“吊眼”等;再如:spring(弹簧),part(零部件),valve face(气门锥面),springhouse(弹簧套)等。 1.3 縮略词大量使用汽车专业英语中的缩略词主要是专业词组,一般是由词组中每个单词的首字母或由单词中的部分字母组成。使用缩略词的目的是为了表达得简洁、直观。汽车专业英语中的缩略词主要有节略词,缩略词,首字词和缩写词几种形式:①节略词:由单词后面的词根或者由单词前面的几个字母组成。如:di(a)——diameter,chute——parachute,lab——laboratory等。②缩略词:由短语中的一些词的词头字母组成,按照正常词的发音规则发音。如Radar——radio detecting and ranging(雷达)。③首字词:由词组中每一个单词的首字母组成,发音时再逐个字母念出。如:CPS——Camshaft Position Sensor(凸轮轴位置传感器),ECI——Electronic Controlled Ignition(电子控制点火)。④缩写词:由一个单词变化而来,且大多数缩写词后面都附有一个圆点。如:Auto.——Automobile(汽车),fig.——figure(图)。 1.4 采用构词法汽车专业英语中的大量词汇都是由构词法转化、合成、派生出来的,尤其是由词缀和词根构成的合成词。例如:有前缀“semi-(半,部分,不完全)”的词有semiconductor(半导体),semiempirical(半经验的),semielectronic(半电子的)等等。 2 汽车专业英语句法特点 2.1 广泛使用被动语态科技文章侧重叙事、推理,强调客观、准确,其所强调的重点是“事物所发生的情况”,即着重体现所表述内容的客观性,因而大量采用第三人称叙述,使用被动语态。过多使用第一、第二人称,会造成主观臆断的现象。汽车英语中的谓语至少三分之一是被动语态。例如:The camshaft is
