如果在高速挂N档在挂会档，也就是自动变速箱进行空挡滑行。这样的操作后，一般不会出现问题。但是有损坏变速箱的风险。
山东变速箱维修厂家提醒，在自动变速箱的使用中，严格要求不可以进行N挡滑行。
If the N gear is engaged at high speed and the meeting gear is engaged, the automatic transmission will coast in neutral. After such operations, there is generally no problem. However, there is a risk of damage to the transmission. Shandong gearbox maintenance manufacturer reminded that N gear sliding is strictly prohibited in the use of automatic gearbox.
车辆在正常行驶一段时间，在急加油或者时速在100公里以上的时后，会有严重耸车的情况，刚开始时试车现象并不明显，后面热车之后就非常明显的冲击顿挫问题了，基本就能确定故障出现在变速箱内部了，拆卸分解变速箱，发现内部的副压力缸损毁严重，其他零部件也是有不同程度磨损，了解到他有在高速行驶时挂空挡滑行的驾驶习惯，导致变速箱内部因为高速运转时得不到充分润滑而损坏。
After a period of normal driving, when the vehicle is refueled quickly or the speed is more than 100km/h, it will have a serious shrug. At the beginning of the test run, the phenomenon is not obvious. After the hot car, there is a very obvious impact problem. It can be basically determined that the fault occurs inside the gearbox. Disassemble the gearbox and find that the internal auxiliary pressure cylinder is seriously damaged, and other parts are also worn to varying degrees, It is learned that he has the driving habit of sliding in neutral gear at high speed, which leads to damage to the inside of the gearbox due to insufficient lubrication at high speed.
之所以自动变速箱禁止N挡滑行，是因为有有一定的几率导致“行星齿轮组”在高速空转中得不到油泵足够量的润滑油，行星齿轮组的润滑能力就不足了，存在被过度磨损的可能性！但一般如果不是长期这样操作，只是偶尔误操作了，对变速箱基本上没有伤害。
The reason why the automatic transmission forbids N gear sliding is that there is a certain probability that the "planetary gear set" will not get enough lubricating oil from the oil pump during high-speed idling, and the lubricating capacity of the planetary gear set will be insufficient, which may lead to excessive wear! However, if the operation is not carried out for a long time, it is only occasionally misoperated, which basically does no harm to the transmission.
因为自动变速箱即便空档，油泵依然继续工作，理论上对行星齿轮组的供油量是完全够用的，但存在不够用的“概率”，所以为了规避变速箱损坏的风险，偶尔的一次低负荷、短距离N档滑行是没有问题的，而高负荷、长距离N档滑行有小的机会会损坏行星齿轮组，所以尽量不要用N档滑行下坡。
Even if the automatic transmission is in neutral, the oil pump still works. Theoretically, the oil supply to the planetary gear set is sufficient, but there is a "probability" that it is not enough. Therefore, in order to avoid the risk of damage to the transmission, it is no problem to occasionally coast at N gear with low load and short distance. However, there is a small chance that high load and long distance N gear coasts will damage the planetary gear set. Therefore, it is best not to coast down the slope at N gear.
自动变速箱的油泵靠发动机的飞轮来带动，而变速箱的散热和液压来自油泵运转时产生的压力，当汽车正常运行时，挂入空挡，则，汽车高速行驶，带动变速箱内的部分部件高速运转，而发动机怠速运转。
The oil pump of the automatic transmission is driven by the flywheel of the engine, while the heat dissipation and hydraulic pressure of the transmission come from the pressure generated by the operation of the oil pump. When the car is in normal operation and is in neutral gear, the car runs at high speed, driving some parts of the gearbox to run at high speed, while the engine runs at idle speed.
于是，自动变速箱的油泵也以发动机的怠速转速运转，由此产生的液压压力和润滑压力（散热）或者称流量，不足以供应自动变速箱内高速运转部件的润滑或散热，后导致变速箱因散热不足使得内部离合器烧损。
As a result, the oil pump of the automatic transmission also runs at the idle speed of the engine, and the resulting hydraulic pressure and lubrication pressure (heat dissipation) or flow is insufficient to supply lubrication or heat dissipation for high-speed running parts of the automatic transmission, which causes the internal clutch of the transmission to burn due to insufficient heat dissipation.
就安全而言，一般影响不大，不至于车毁人亡（有特殊情况的另言）。对变速箱而言，偶尔的超短时间N档，不会有什么影响，长时间（也可能十多分钟）就会导致打滑烧片！烧片后的处理方法：大修变速箱。
As far as safety is concerned, the impact is generally small, not to the extent of vehicle damage and death (otherwise, in special circumstances). For the transmission, the occasional ultra short time of N gear will not have any impact, and a long time (or more than ten minutes) will lead to slipping and burning! Treatment method after burning: overhaul the gearbox.
Is there any damage to the transmission caused by automatic neutral sliding? From the above explanation, we can get the answer, there will be, so try to avoid this kind of wrong operation. You can come to our website anytime if you have any idea about this http://www.jnbsx.com Consult!
