汽车底盘中英文翻译
汽车底盘中英文翻译1 .ChassisThe chassis is an assembly of those systems that are the major operating part of a vehicle. The chassis includes the transmission, suspension, steering, and brake systems.Transmission systems ― conveys the drive to the wheels. The ma in components are clutch, gearbox, driveshaft, final drive, and differential.Suspension― absorbs the road shocks.Steering― controls the direction of the movement.Brake― slows down the vehicle.Automobile Brake SystemThe braking system is the most important system in cars. If the brakes fail, the result can be disastrous. Brakes are actually energy conversion devices, which convert the kinetic energy (momentum) of the vehicle into thermal energy (heat).When stepping on the brakes, the driver commands a stopping force ten times as powerful as the force that puts the car in motion. The braking system can exert thousands of pounds of pressure on each of the four brakes.Two complete independent braking systems are used on the car. They are the service brake and the parking brake.The service brake acts to slow, stop, or hold the vehicle during normal driving. They are foot-operated by the driver depressing and releasing the brake pedal. The primary purpose of the parking brake is to hold the vehicle stationary while it is unattended. The parking brake is mechanically operated by when a separate parking brake foot pedal or hand lever is set.The brake system is composed of the following basic components: the “master cylinder”which is located under the hood, and is directly connected to the brake pedal, converts driver foot’s mechanical pressure into hydraulic pressure. Steel “brake lines”and flexible “brake hoses”connect the master cylinder to the “slave cylinders”located at each wheel. Brake fluid, specially designed to work in extreme conditions, fills the system. “Shoes”and “pads”are pushed by the slave cylinders to contact the “drums”and “rotors”thus causing drag, which (hopefully) slows the car.The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder.Basically, all car brakes are friction brakes. When the driver applies the brake, the control device forces brake shoes, or pads, against the rotating brake drum or disks at wheel. Friction between the shoes or pads and the drums or disks then slows or stops the wheel so that the car is braked.In most modern brake systems, there is a fluid-filled cylinder, called master cylinder, which contains two separate sections, there is a piston in each section and both pistons are connected to a brake pedal in the driver’s compartment. When thebrake is pushed down, brake fluid is sent from the master cylinder to the wheels. At the wheels, the fluid pushes shoes, or pads, against revolving drums or disks. The friction between the stationary shoes, or pads, and the revolving drums or disks slows and stops them. This slows or stops the revolving wheels, which, in turn, slow or stop the car.The brake fluid reservoir is on top of the master cylinder. Most cars today have a transparent reservoir so that you can see the level without opening the cover. The brake fluid level will drop slightly as the brake pads wear. This is a normal condition and no cause for concern. If the level drops noticeably over a short period of time or goes down to about two thirds full, have your brakes checked as soon as possible. Keep the reservoir covered except for the amount of time you need to fill it and never leave a cam of brake fluid uncovered. Brake fluid must maintain a very high boiling point. Exposure to air will cause the fluid to absorb moisture which will lower that boiling point.The brake fluid travels from the master cylinder to the wheels through a series of steel tubes and reinforced rubber hoses. Rubber hoses are only used in places that require flexibility, such as at the front wheels, which move up and down as well as steer. The rest of the system uses non-corrosive seamless steel tubing with special fittings at all attachment points. If a steel line requires a repair, the best procedure is to replace the compete line. If this is not practical, a line can be repaired using special splice fittings that are made for brake system repair. You must never use copper tubing to repair a brake system. They are dangerous and illegal.Drum brakes, it consists of the brake drum, an expander, pull back springs, a stationary back plate, two shoes with friction linings, and anchor pins. The stationary back plate is secured to the flange of the axle housing or to the steering knuckle. The brake drum is mounted on the wheel hub. There is a clearance between the inner surface of the drum and the shoe lining. To apply brakes, the driver pushes pedal, the expander expands the shoes and presses them to the drum. Friction between the brake drum and the friction linings brakes the wheels and the vehicle stops. To release brakes, the driver release the pedal, the pull back spring retracts the shoes thus permitting free rotation of the wheels.Disk brakes, it has a metal disk instead of a drum. A flat shoe, or disk-brake pad, is located on each side of the disk. The shoes squeeze the rotating disk to stop the car. Fluid from the master cylinder forces the pistons to move in, toward the disk. This action pushes the friction pads tightly against the disk. The friction between the shoes and disk slows and stops it. This provides the braking action. Pistons are made of either plastic or metal. There are three general types of disk brakes. They are the floating-caliper type, the fixed-caliper type, and the sliding-caliper type. Floating-caliper and sliding-caliper disk brakes use a single piston. Fixed-caliper disk brakes have either two or four pistons.Steering SystemBasic Parts of Steering SystemThe steering converts the steering –wheel rotary motion into a turn motion of the steered wheels of the vehicle .The basic steering system in most cars is the same . The steering gear of steering box is the heart of the steering system .This is usually next to the engine . A shaft extends from the back of the steering gear . This shaft is connected to the steering column or steering shaft . The steering wheel is at the top of the steering column . Another shaft comes from the bottom of the steering gear . This shaft connects to the arms , rods , and links . This parts assembly , called the steering linkage , connects the steering gear to the parts at the wheels . The wheels and tires mount to the steering knuckles , the knuckles are pivoted at the top and bottom . Thus , the wheels and rites can turn from side to side .While the steering system may look complicated , it works quite simply . When a driver drives a car straight down the road , the steering gear is centered . The gear holds the linkage centered so that the wheels and tires point straight ahead . When the driver turns the steering wheel , the steering shaft rotates and the steering gear moves toward that side . The shaft coming out the bottom of the steering gear turns , as well . When the shaft turns , it pulls the linkage to one side and makes the steering knuckles turn slightly about their pivot points . Thus , the steering knuckle , spindle , wheels , and tires turn to one side , causing the car to turn .The type of steering layout depends on the suspension system . The beam axle used on heavy commercial vehicle has a king pin fitted at each end of the axle and this pin is the pivot which allows the wheels to be steered . Cars have independent suspension and this system has ball joints to allow for wheel movement .Types of Steering SystemA steering box must have the following qualities :1) no play in the straight-ahead position2)low friction , resulting in high efficiency3)high rigidity ,4)readjustabilityFor these reasons , these are several different types of steering gears . However , there are only two types of steering systems : manual steering systems and power steering systems . In the manual type , the driver dose all the work of turning the steering wheel , steering gear , wheels and tires . In the power , hydraulic fluid assists the operation so that driver effort is reduced .On today’s cars , two types of steering systems commonly are used to provide steering control :1) recirculating ball2) rack and pinionEither of these two types of steering mechanisms may be a fully mechanical systems or a power –assisted system .Front SuspensionThe front suspension is more complicated than the rear suspension . This is because the front wheels must move in several different directions . The wheels must move up and down with the suspension and turn left to right with the steering . Since the car goes in the direction in which the front wheels point , the alignment of the front wheels is important . The wheels must point in just the right direction for the carto move straight down the road and turn properly .Modern cars uses an independent front suspension . In this system , each wheel mounts separately to the frame and has its own individual spring and shock absorber . Thus , the wheels act independently of one another . When one wheel hits a bump or hole in the road , the other wheel dose not deflect .Front Wheel AlignmentAs a car moves down the high-way , the suspension moves the front wheels up and down . At the same time , the steering mechanism moves the front wheels , sometimes to make turns and sometimes to make the travel straight . The angular relationship between the wheels and suspension parts during this motion is the front-end geometry . Since the geometry can change the alignment of front wheels is adjustable . You can change the adjustment to compensate for spring sag .The alignment of the front wheels affects the operation of a car . 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 . The three normally adjustable angles are caster , camber , and toe .Rear SuspensionThe purpose of the rear suspension is to support the weight of the rear of the vehicle . As with the front suspension , this system contributes to the stability and ride of the vehicle . Rear suspension may be of the solid axle or independent design . Many cars have solid axle rear suspension . Either design may have different kinds of springs , including torsion bars . However , the coil spring and leaf spring types are most popular .WheelsThe rim is made in one piece , with the wheel center welded or riveted to it . Most modern vehicles use the drop center type . This drop center provides a well for tire bead to drop into for tire removal . A slight hump at the head ledge holds the tire in place should it go flat while driving .TiresTires are important to your safety and comfort . They transmit the driving and brak ing power to the road . The car’s directional control , road-ability and riding comfort are greatly dependent on the tires . Tires should be selected and maintained with great care .There are two basic types of tires –those with inner tubes and those without ( called “tubeless” tires ) . Most modern automobile tires are of the tubeless type . Truck and bus tire are usually of the tube type .Tires are made of several layers of nylon , rayon , or polyester fabric bonded together with belts of rayon , fiberglass , or steel cord . The rubber used in tires is a blend of natural and synthetic rubber .2.底盘底盘由汽车的主要操作部分组合而成。

2. Car body
An automobile body is a sheet metal shell with windows, doors, a hood and a trunk deck built into it. It provide a protective covering for the engine, passengers.
Final drive is inside the drive axle. The drive axle consists of axle housing,final drive, differential and half axle. Final drive's main role is to output the transmission power to further reduce the speed, increase the torque and change the direction of rotation, and then passed to the drive wheels, to gain enough traction and appropriate car speed.

第二部分底盘CHASIS一、齿轮Gears齿轮用于两个不同传递的轴之间的动力传递。
齿轮有很多作用，但最重要的作用是动力设备的减速。
这主要是因为，通常，当小小的电机高速运转时，虽然能提供足够的功率，但不能提供足够的力矩。
如果使用齿轮减速，就可以降低输出速度，同时增加力矩。
Gears are used to transmit power between shafts rotating usually at different speeds. Gears do several important jobs, but most important, they provide a gear reduction in motorized equipment. This is key because, often, a small motor spinning very fast can provide enough power for a device, but not enough torque. With a gear reduction, the output speed can be reduced while the torque is increased.齿轮的另一个作用是改变旋转方向。
例如，汽车的差速器必须将动力转90度传递给车轮。
Another thing gears do is adjust the direction of rotation. For instance, the differential of car has to turn power 90 degrees to apply it to the wheels.传动比是由两轮的中心到啮合点的距离所决定的。
例如，两个齿轮的传动机构中，如果一齿轮的尺寸是另一齿轮的两倍，那么传动比就是2：1.The ratio is determined by the distances from the center of the gear to the point of contact. For instance, in a device with two gears, if one gear is twice the size of the other, the ratio would be 2:1.这种齿轮传动的缺陷在于，每隔齿轮的中心到啮合点的距离在运转的过程中是变化的。
也就是说，当齿轮转动时，齿轮的传动比是变化的，那就意味着输出速度也会变化。
假如你的车内使用这种齿轮，那么你就不可能保持稳定的速度-你就一直在加速或减速。
The problem with this type of gear is that the distance from the center of each gear to the point of contact changes as the gears rotate. This means that the gear ratio changes as the gear turns, meaning that the output speed also changes. If you used a gear like this in your car, it would be impossible to maintain a constant speed-you would be accelerating and decelerating constantly. 很多现代齿轮使用一种称为渐开线的齿廓。
这种轮廓的齿轮具有特别重要的性质，就是保持两轮间稳定的传动比。
Many modern gears use a special tooth profile called an involute. This profile has the very important property of maintaining a constant speed into between the two gears.下面就介绍其中的几种齿轮：Some of the many types of gears are illustrated below:1、直齿轮Spur Gears安装在两根平行轴上的直齿轮最常见的齿轮，这种齿轮带直齿。
有时，一次用多级齿轮传动可获得大的降速比。
A pair of spur gears for mounting on parallel shafts are the most common type of gears, which have straight teeth. Sometimes, many spur gears are used at once to create very large gear reductions.直齿轮运行时噪音很大。
每次一齿轮与另一齿轮啮合时，齿间就发生冲击，从而产生噪音，同时也增加了齿面上的压应力。
The spur gear can be really loud. Each time a gear tooth engages a tooth on the other gear, the teeth collide, and this impact makes a noise. It also increases the stress on the gear teeth.为了降低噪音、减小应力，我们的轿车较多地使用斜齿轮。
To reduce the noise and stress in the gears, most of the gears in your car are helical.2、斜齿轮Helical Gears和直齿轮一样。
斜齿轮也安装在两根平行轴上，但是，斜齿轮上的齿与轴线不是平行的，而是成一斜角。
当两齿啮合时，齿面由一个头开始啮合，并在运转时逐步扩大接触面，直到全齿完全啮合。
Like spur gears helical gears connect parallel shafts, however the teeth are not parallel to the shaft axes but lie along helices about the axes. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement.逐步啮合的过程是斜齿轮在运转时，比直齿轮更平缓、噪音更低。
正因如此，几乎所有轿车的传动系统都使用斜齿轮。
因为斜齿轮的齿有个角度，所以，在其啮合时就会产生轴向推力。
所以采用斜齿轮的机构均使用能承受轴向载荷的轴承。
This gradual engagement makes helical gears operate much more smoothly and quietly than spur gears. For this reason, helical gears are used in almost all car transmissions. Because of the angle of the teeth on helical gears, they create a thrust load on the gear when they mesh. Devices that use helical gears have bearings that can support this thrust load.3、錐齿轮Bevel Gears当两传动轴旋转时需改变方向时，采用锥齿轮是一种十分有用的方法。
通常，锥齿轮的两轴呈90度，但也可以设计成其他角度。
Bevel gears are useful when the direction of a shaft’s rotation needs to be changed. They are usually mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well.锥齿轮的齿可以是直齿、螺旋形或准双曲面。
直齿锥齿轮和直齿轮存在这同样的问题----齿的啮合过程中始终存在冲击。
就像直齿轮一样，这个问题的解决也是将轮齿变为曲线。
螺旋锥齿轮的啮合和斜齿轮是一样的：齿面由一个断面进入啮合，逐步扩大接触面，直到全齿完全啮合。
The teeth on bevel gears can be straight, spiral or hypoid. Straight bevel gear teeth actually have the same problem as straight spur gear teeth-as each tooth engages, it impacts the corresponding tooth all at once. Just like with spur gears, the solution to this problem is to curve the gear teeth. These spiral teeth engage just like helical teeth: the contact starts at one end of the gear and progressively spreads across the whole tooth.4、蜗轮蜗杆Worm Gears涡轮和蜗杆可获得很大的降速比，但是存在严重的相对滑动。
通常蜗轮蜗杆的减速比可达到20：1，甚至达到300：1或更大。
A worm and worm wheel gives a large speed ratio but with significant sliding. It is common for worm gears to have reductions of 20:1, and even up to 300:1 or greater.很多蜗轮蜗杆具有其他齿轮传动所没有的一种有趣的性质：蜗杆能很容易地带动涡轮，但是涡轮却带不动蜗杆。
