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。

Slipping automatic transmission?

首先检查液位。大多数汽车将有正确的方式检查液位,在传输浸渍棒中冲压。如果没有,请检查您的汽车所有者手册。如果流体水平足够低,低流体会导致变速器滑动或不换档。重要的是要了解为什么水平低,或换句话说,找到泄漏。检查平底锅垫片(传动中心),输入轴(变速器正面)或输出轴(传输后部)如果泄漏足够慢,可以开车到车库,但请牢记驾驶您的汽车用低传输液驾驶汽车由于过热和润滑不当导致损坏。

汽车传动系统

我的传输,驱动轴和后桥如何工作?

From the Transmission, through the drive shaft and ending up in your rear axle, the torque your engine produces reaches the road through your car's drivetrain. Learn the differences between front and rear wheel drive systems, common problems and more...

传动系统的安排

We need to get this out of the way before we can define parts, and talk about their function. Ever confusing, the arrangement of modern drivetrains is sometimes misunderstood. Let's look at the common arrangements and their strengths and weaknesses...

  • Rear Wheel Drive (RWD):The most common layout for older vehicles and most trucks. Power runs from the engine through a transmission and driveshaft to an axle at the rear of the vehicle.
  • 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-Wheel Drive (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

The Transmission:无论在上面详述的动力传动系统安排,它们都有传播。传输是用于乘以扭矩的装置,并且允许更高的速度。想象一下,由于发动机的vwin手机客户端电源曲线,RPM限制和后轴的固定比,汽车的速度范围是严重限制的,想象一下直接连接到后轴的发动机。它可以从死区停止时加速,但不能达到更高的速度,或者在更高的速度下加速和运行很慢。通过改变每个齿轮中的比率,现代变速器允许可以从止动件加速良好的汽车并实现更高的速度。回到50年代和60年代的变速箱,最多有3或4档,今天的新车最多可以有8个齿轮,大型拖拉机拖车可以有21个或更多的齿轮来移动重载。通过保持发动机RPM在最佳范围内,更多的齿轮允许更好的发动vwin手机客户端机效率。在柴油发动机大型公路卡车的情况下,他们的操作vwin手机客户端RPM范围要窄得多,因此需要更多的齿轮。

Transmissions can come in 3 styles... Manual, Automatic and Constant Velocity (CV) Manual transmissions are connected to the engine with a clutch which allows the driver to engage and disengage the transmission from the engine when the car is stopped or between gear changes. The manual transmission allows for gear changes through a lever, or shifter which manually moves the gear sets into the proper position for the gear desired.

自动变速器是当今汽车和卡车中最常见的传输。它们依赖于流体填充的扭矩转换器,其允许发动机和变速器之间的间接连接。vwin手机客户端当自动移入驱动位置(P-R-N-D-2-1)并且汽车处于停止时,扭矩转换器允许一些滑动,因此发动机不会失速。vwin手机客户端这也允许换档比手动传输更光滑,但确实导致效率低下的损失。

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:The driveshaft takes the power from the transmission in a RWD car and transmits it to the rear axle. Since the rear suspension moves up and down, the driveshaft must move as well. Universal joints are used at both ends to allow the driveshaft to move with the suspension and still rotate plus a sliding slip joint must also be employed to extend or contract as the driveshaft moves in and out of the transmission. The driveshaft is most commonly made from steel, but can also be made from aluminum or in exotic cases carbon fiber.

Rear Axle:The rear axle is found on RWD, 4WD and AWD cars, trucks and SUVs. The rear axle takes the rotation of the driveshaft, turns it 90 degrees and distributes it to the two rear wheels. It's job is to make sure that power goes to the rear wheels in the proper proportion. A funny thing happens when turning a corner, the inside wheel (to the turn) turns slower than the outside wheel. The rear axle's differential allows for the inner wheel to slow down while sending power to the outer wheel to complete the turn.

转移案例:In AWD and 4WD cars and trucks, the transfer case splits the engines torque to the front and rear axles. Depending on your car or truck, the transfer case may have several gears to allow for different driving conditions. Think of it as an extra gear that lowers or raises the operating range of the transmission. When going slowly off-road over rocks and up steep hills, speed is not an issue, so a lower range of gearing will multiply torque and allow you to get to your destination. For highway driving the higher range of your transfer case will allow for higher speeds, but less torque.

TransaxLe:Simply a combination of the transmission and axle, commonly found in FWD cars although in cases like the Corvette it can be found in RWD cars on occasion. More compact but usually a little more complicated as well, when replacement is needed the costs can be higher than if the components we separate.

前桥轴:在FWD汽车或大多数AWD汽车的情况下,轮廓泄漏或轴将连接到具有前轴轴的轮子。与驱动轴类似,但更复杂,因为前轮也可以随着方向盘转动,以允许您的车转转。前桥轴具有两个CV(恒定速度)接头,其允许多种运动范围而不是通用接头。它们通常不作为通用接头处理的扭矩,因此在大多数重型4WD卡车中,通用接头与固体活轴一起使用。

常见问题:

  • Manual transmission suffer from wear mainly in the synchronizers. The synchronizers make shifting easier and help to prevent gear clash. Over time the synchronizers, which are made of brass, can wear out causing hard shifting and grinding.
  • 自动变速器也可以磨损,引起滑动和不均匀的换档图案。
  • Universal joints can wear and cause vibrations while driving. Many newer universal joints are sealed and can not be lubricated, leaving replacement as the only option.

预防性的维护:

  • Change the fluid in your transmission at recommended intervals. Your owners manual will give you a time schedule in miles and or months. If you tow a boat or trailer be prepared to change the fluid even sooner. Most owners manuals will give you recommend intervals for severe use like towing or off-road use.
  • 不“骑”离合器如果你有一个手动tran吗smission. Learn to release the clutch in a smooth motion without revving the engine too much. Revving the engine too much while pulling out can cause premature wear on the clutch.
  • 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。
  • 如果您有一个前轮驱动车,请避免在全锁时将气体施加到地板上。这对普遍造成了压力,可能导致过早失败。当困在雪地里试图出来时,这可能会发生。

与您的机械师讨论什么:

  • 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?
  • 确保在决定获得新的或重建传输时,您可以获得保修和价格的所有细节,以便您可以做出受过教育的决定。大多数时候你会更好地获得重建传输,但如果你计划让你的车保持更多的岁月,而且新的传输并不贵,它可能是一个不错的选择。
  • 当获得换油或其他常规服务时,请确保机械师润滑任何通用接头,如果装备,请检查CV接头靴,并检查变速器中的液位。通过保持物品润滑,您将获得最长的寿命。
