振动?

追踪振动可能是艰难的,这里有几个提示。在裤子的座位上通常会感受到动力传动系统的振动,并且可以随着天然气踏板的应用而变得更好或更糟。在速度较高时驾驶时,如果在沿一个方向转动时振动变得更糟,它可能是一个轮轴。感觉到它来自车辆中心的恒定振动可以是驱动轴通用接头(后轮驱动车辆)轮毂,其超出平衡也会导致振动,并且有时可以在方向盘中感受到振动。

滑动自动变速箱?

First check fluid level. Most cars will have instructions on the proper way to check fluid level, stamped right in the transmission dip stick. If not, check your car's owners manual. Low fluid will cause the transmission to slip or not go in gear if the fluid level is low enough. It's important to find out why the level is low, or in other words, find the leak. Check pan gasket (center of transmission), input shaft (front of transmission) or the output shaft (rear of transmission) If the leak is slow enough, you can drive to a garage, but keep in mind driving your car with low transmission fluid can cause damage due to overheating and improper lubrication.

汽车传动系统

How does my transmission, driveshaft and rear axle work?

从传动,通过驱动轴并在后桥中结束,发动机的扭矩通过汽车的动力传动系统到达道路。vwin手机客户端了解前轮驱动系统,常见问题和更多的差异......

传动系统的安排

在我们可以定义部分之前,我们需要在某种程度上得到这种方式,并谈谈它们的功能。令人困惑的是,现代动力测定的安排有时会被误解。让我们来看看共同的安排及其优势和弱点......

  • 后轮驱动(RWD):老车辆和大多数卡车最常见的布局。电力通过发动机通过传输和驱动轴运行到车辆vwin手机客户端后部的轴上。
  • 前轮驱动(FWD):自20世纪80年代以来,大多数经济汽车的标准布局甚至是一些紧凑的SUV。来自发动机的电源通过轮廓泄漏(变vwin手机客户端速器和轴的组合),并通过轴轴前进到前轮。前轮驱动布局的主要优点是发动机的重量在驱动轮上,提供更好的牵引力。vwin手机客户端缺点是,对于表现形式的主人,体重平衡和扭矩操舵是一个问题。扭矩转向是通过前轮转向地面的自然反应,当你真正踩到气体时,在方向盘上被出现在方向盘上。
  • 4轮驱动(4WD):从发动机到传输的电源,然后通过驱动轴分开到vwin手机客户端前后轴。在卡车和一些SUV的转移案例上有几个“范围”,以满足不同的驾驶条件。最典型的安排是2WD / HI / LO,在那里您将在其中选择2WD的时间,在那里您不需要所有4个轮子的牵引力,并希望更好的气体里程。嗨范围是时候需要所有4个轮子拉动,你将推动高速公路速度。当您需要具有较低轮速的最大扭矩时,LO为越野,低速驱动。
  • 所有轮子驱动器(AWD):非常类似于4WD,但所有4个轮子都是由发动机的“全部”时间驱动。vwin手机客户端可能有一个嗨/ lo选项,但没有2wd可用。大多数现代的SUV和汽车都是AWD。各种条件下的优点是统计牵引力,较少的运动零件比4WD系统更加紧凑,用于安装汽车。

动力传动系统的组成部分

传输:No matter the drivetrain arrangement detailed above, they all have a transmission. The transmission is a device used to multiply torque and allow for higher speeds. Imagine an engine which was directly connected to the rear axle, due to the power curve of the engine, RPM limits and the fixed ratio of the rear axle, the speed range of the car would be severely limited. It would either accelerate very well from a dead-stop but not be able to achieve higher speeds, or it would be slow to accelerate and run well at higher speeds. By varying the ratios in each gear, the modern transmission allows for a car which can accelerate well from a stop and achieve higher speeds. Back in the 50's and 60's transmissions had 3 or 4 gear at most, today new cars can have up to 8 gears and large tractor trailers can have 21 or more gears to move heavy loads. More gears allows for better engine efficiency by keeping the engine RPM's in an optimal range. In the case of diesel engines in large over the road trucks, their operating RPM range is much narrower, so more gears are needed.

传输可以进入3个风格...手动,自动和恒定速度(CV)手动变速器与离合器连接到发动机,当汽车停止或在齿轮变化之间时,允许驾驶员从发动机接合和脱离传动vwin手机客户端。手动变速器允许齿轮通过杠杆变化,或者移位器,该杠杆手动将齿轮组移动到所需档位的适当位置。

Automatic Transmissions are the most common transmissions found in cars and trucks today. They rely on a fluid filled torque converter which allows an indirect connection between the engine and transmission. When an automatic is shifted in to the Drive position (P-R-N-D-2-1) and the car is at a stop, the torque converter allows some slipping, so the engine does not stall. This also allows the shifts to be smoother than a manual transmission, but does result in a slight loss in inefficiency.

CVT或恒定的可变变速器是在几辆新车(奥迪,BMW,GM和FORD)中发现的一种传输。虽然CVT传输已经存在于雪地车和其他娱乐车辆的岁月,但最近,它才允许现代材料允许他们采取扭矩并滥用被送入汽车。CVT变速器没有任何齿轮,而是两组板移动和改变发动机和车轮之间的比率。vwin手机客户端在这两组板之间,存在透射扭矩的带。CVT不提供齿轮变化的中断,操作平滑,更好的燃料经济性。一些CVTS可以提供​​“齿轮”,但实际上只是在手动或自动变速器中模仿传统齿轮变化的板条中的设定值。虽然一个复杂的主题,并简化了本课程,您可以通过访问来了解有关CVT传输的更多信息这一页。

驱动轴:驱动轴从RWD汽车中的变速器中汲取功率,并将其传递给后轴。由于后悬架上下移动,驱动轴也必须移动。在两端使用通用接头以允许驱动轴与悬架一起移动,并且仍然旋转加载滑动接头,也必须使用驱动轴进出传输时延伸或收缩。驱动轴最常由钢制成,但也可以由铝或异国情调的碳纤维制成。

后轴:后轴在RWD,4WD和AWD汽车,卡车和SUV上找到。后轴取向驱动轴的旋转,将其转动90度并将其分配到两个后轮。这是工作是以适当的比例确保电力进入后轮。转动角落时发生了一件有趣的事情,内轮(转弯)变得慢于外轮。后轴的差速器允许内轮在向外车轮发送电力时慢下来,以完成转弯。

转移案例:在AWD和4WD汽车和卡车中,传送盒将发动机转矩与前轴和后轴分配。vwin手机客户端根据您的汽车或卡车,转移壳体可以具有多个齿轮,以允许不同的驾驶条件。将其视为额外的齿轮,可降低或提高变速器的操作范围。在岩石和陡峭的山坡上慢慢越野时,速度不是问题,因此较低范围的传动装置将乘以扭矩并允许您到达目的地。对于高速公路驾驶较高范围的转移箱将允许更高的速度,但扭矩较小。

TransaxLe:只需在FWD汽车中常见的传输和轴的组合,尽管在像Corvette这样的情况下,它可以在RWD汽车中找到。更紧凑但通常有点复杂,当需要更换时,费用可以高于我们分开的组件。

前桥轴:In the case of FWD cars, or most AWD cars, the transaxle or axle will connect to the wheels with a front axle shaft. Similar to a drive shaft, but more complex since the front wheels can also turn with the steering wheel to allow your car to make a turn. The front axle shaft has two CV (constant velocity) joints which allow a great range of motion than a universal joint. They do not typically handle as much torque as a universal joint so in most heavy duty 4WD trucks, a universal joint is used with a solid live axle.

Common Problems:

  • 手动变速器主要在同步器中磨损。Synchronizers使移位更容易,有助于防止齿轮冲突。随着时间的推移,由黄铜制成的同步器可以磨损导致硬移位和研磨。
  • 自动变速器也可以磨损,引起滑动和不均匀的换档图案。
  • 通用接头可以在驾驶时磨损和造成振动。许多较新的通用接头被密封,不能润滑,作为唯一的选择。

Preventive Maintenance:

  • 以推荐的间隔更换传输中的流体。您的业​​主手册将为您提供数英里或几个月的时间表。如果你拖船或拖车准备好更快地改变流体。大多数所有者手册将为您推荐严重使用的间隔,如牵引或越野使用。
  • 如果您有手动传输,请勿“乘坐”离合器。学习在平滑的运动中释放离合器,而不会过分向发动机翻转发动机。vwin手机客户端在拔出时旋转过多的发动机vwin手机客户端会导致离合器上的过早磨损。
  • 如果您拖船或拖车,请考虑获得自动变速器的传输冷却器。温度可以在严重条件下接近沸点。如果销售牵引套,大多数较新的卡车都配备了传动冷却器。
  • 如果它们是可以润滑的类型,请确保您的通用接头在换油时润滑。更换通用接头时,请尝试使用润滑配件找到更换,以便您将来润滑。
  • If you have a front wheel drive car, avoid applying the gas to the floor while the wheels are turned at full lock. This puts stress on the universals and can cause premature failure. This can happen when stuck in the snow and trying to get out.

What to discuss with your mechanic:

  • 如果您在驾驶时注意到汽车中的振动,请务必在发生这种情况时描述。加速?制动?保持速度?转身时?
  • Make sure when deciding to get a new or rebuilt transmission, that you have all the details of warranty and prices so you can make an educated decision. Most times you will be better off getting a rebuilt transmission, but if you plan on keeping your car for many more years, and the new transmission is not much more expensive, it could be a good choice.
  • 当换油或其他定期检修e, make sure your mechanic lubricates any universal joints, inspects the CV joint boots if equipped and checks fluid level in your transmission. By keeping the items lubricated, you will get the longest possible life out of them.
