汽车转速高但是速度提升的慢是怎么回事?

  转速高,可是速度提升很慢,这是怎么回事呢?
  The speed is high, but the speed is rising slowly. What's the matter?
  这是个很经典的问题,相信不少车主遇见过。别以为就老车会出现这问题,新车“也会”,当然前提是配个新司机。别等到跑高速时候,使劲踩油门,转速都3、4000了,可是速度还在8、90km/h,这时候你郁闷也没用。所以,下面的内容get起来吧。
  This is a classic problem. I believe many car owners have met it. Don't think the old car will have this problem. The new car will, of course, only if it is equipped with a new driver. Don't wait until you run at high speed, press the accelerator hard, the speed is 3 or 4000, but the speed is still 8 or 90km / h, so it's useless to be depressed at this time. So get it up.
  我们可以先看一下车辆的动力是怎么来的:首先我们踩油门→发动机电脑根据油门信号控制进气和喷油→汽油和空气进入气缸混合→火花塞点燃混合气推动活塞运动→带动曲轴转动,至此发动机有了动力。
  We can first see how the power of the vehicle comes from: first, we step on the accelerator → the engine computer controls the intake and injection according to the accelerator signal → gasoline and air enter the cylinder for mixing → the spark plug ignites the mixture to push the piston to move → drive the crankshaft to rotate, so the engine has power.
  然后动力按下图所示的经过离合器、变速箱、传动轴、差速器、半轴的传递到达驱动轮,这样车辆就动起来了,产生了速度。
  Then the power passes through the clutch, gearbox, transmission shaft, differential and half shaft as shown in the figure below and reaches the driving wheel, so that the vehicle moves and produces speed.
  发动机转速可以提高,一般来说发动机这方面是正常的。有的朋友可能会说缺缸,可是缺缸会导致发动机转速和车子的速度都下降,而不是转速提高,车速没啥动静。所以问题大概率出在传动部件上,而差速器的作用主要在转弯时提供不同的动力分配,关系不大就不多讲了。
  The engine speed can be increased. Generally speaking, the engine is normal. Some friends may say that there is a lack of cylinder, but the lack of cylinder will cause the engine speed and the speed of the car to decrease, rather than increase the speed, and the speed is not very static. So the problem probably lies in the transmission parts, and the function of the differential mainly provides different power distribution when turning. It doesn't matter much.

  所以,导致高转速,速度低的原因具体有下面几点:
  Therefore, the causes of high speed and low speed are as follows:
  1、变速箱/离合器故障:
  1. Transmission / clutch failure:
  a、变速箱油过少,导致油压过低,从而导致离合器和制动器打滑;
  a. Too little oil in the gearbox results in too low oil pressure, which leads to slipping of the clutch and brake;
  b、离合器片或制动器摩擦片磨损或烧蚀,引发打滑;
  b. Friction plate of clutch or brake is worn or ablated, causing slipping;
  c、变速箱油泵、油路、密封圈等存在损坏或泄漏,导致油压过低,引发打滑;
  c. The oil pump, oil circuit and sealing ring of gearbox are damaged or leaked, resulting in low oil pressure and slipping;
  d、单向离合器打滑;
  d. One way clutch slipping;
  e、锁止离合器故障,比如锁在某一档不升档了;
  e. Lock up clutch failure, such as lock in a certain gear does not upshift;
  f、变速箱电脑故障;
  f. Gearbox computer failure;
  g、变速箱阀体故障;
  g. Gearbox valve body failure;
  2、传动轴故障:比如宝马M3/M4就有关于传动轴的召回,长期高负荷使用可能导致传动轴法兰脱出,造成传动轴将打滑,无法加速。
  2. Transmission shaft fault: for example, BMW M3 / M4 has a recall of the transmission shaft. Long term high load use may cause the transmission shaft flange to come out, causing the transmission shaft to slip, unable to accelerate.
  3、半轴故障:与传动轴类似,半轴与驱动轮相连,一旦半轴打滑,作用到驱动轮的动力就下降很多了,速度自然难以提升,这时候驾驶员肯定加深踩油门,发动机转速飙高。
  3. Axle shaft fault: similar to the transmission shaft, the axle shaft is connected to the drive wheel. Once the axle shaft slips, the power acting on the drive wheel will drop a lot, and the speed will be difficult to increase naturally. At this time, the driver must step on the accelerator more deeply, and the engine speed will be high.
  除了上面的主要的故障原因,其实现实中还有很多令人发笑的误操作,也可能导致类似的现象,比如:
  In addition to the above main fault causes, there are many funny misoperations in reality, which may also lead to similar phenomena, such as:
  1、被自己限速而不得知;
  1. Be limited by oneself without knowing;
  2、没注意被乘员切换到了DS档,延迟换挡了;
  2. Didn't notice that the crew switched to DS gear, delayed shifting;
  3、新车,4S忘记给你解除运输模式;
  3. New car, 4S forgot to release the transport mode for you;
  4、忘记放下手刹,你别笑,真有人带手刹跑了上百公里。
  4. Forget to put down the handbrake. Don't laugh. Someone has run hundreds of kilometers with the handbrake.
