如果在高速掛N檔在掛會(huì)檔，也就是自動(dòng)變速箱進(jìn)行空擋滑行。這樣的操作后，一般不會(huì)出現(xiàn)問(wèn)題。但是有損壞變速箱的風(fēng)險(xiǎn)。山東變速箱維修廠家提醒，在自動(dòng)變速箱的使用中，嚴(yán)格要求不可以進(jìn)行N擋滑行。

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.

車(chē)輛在正常行駛一段時(shí)間，在急加油或者時(shí)速在100公里以上的時(shí)后，會(huì)有嚴(yán)重聳車(chē)的情況，剛開(kāi)始時(shí)試車(chē)現(xiàn)象并不明顯，后面熱車(chē)之后就非常明顯的沖擊頓挫問(wèn)題了，基本就能確定故障出現(xiàn)在變速箱內(nèi)部了，拆卸分解變速箱，發(fā)現(xiàn)內(nèi)部的副壓力缸損毀嚴(yán)重，其他零部件也是有不同程度磨損，了解到他有在高速行駛時(shí)掛空擋滑行的駕駛習(xí)慣，導(dǎo)致變速箱內(nèi)部因?yàn)楦咚龠\(yùn)轉(zhuǎn)時(shí)得不到充分潤(rùn)滑而損壞。

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.

之所以自動(dòng)變速箱禁止N擋滑行，是因?yàn)橛杏幸欢ǖ膸茁蕦?dǎo)致“行星齒輪組”在高速空轉(zhuǎn)中得不到油泵足夠量的潤(rùn)滑油，行星齒輪組的潤(rùn)滑能力就不足了，存在被過(guò)度磨損的可能性！但一般如果不是長(zhǎng)期這樣操作，只是偶爾誤操作了，對(duì)變速箱基本上沒(méi)有傷害。

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?yàn)樽詣?dòng)變速箱即便空檔，油泵依然繼續(xù)工作，理論上對(duì)行星齒輪組的供油量是完全夠用的，但存在不夠用的“概率”，所以為了規(guī)避變速箱損壞的風(fēng)險(xiǎn)，偶爾的一次低負(fù)荷、短距離N檔滑行是沒(méi)有問(wèn)題的，而高負(fù)荷、長(zhǎng)距離N檔滑行有小的機(jī)會(huì)會(huì)損壞行星齒輪組，所以盡量不要用N檔滑行下坡。

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.

自動(dòng)變速箱的油泵靠發(fā)動(dòng)機(jī)的飛輪來(lái)帶動(dòng)，而變速箱的散熱和液壓來(lái)自油泵運(yùn)轉(zhuǎn)時(shí)產(chǎn)生的壓力，當(dāng)汽車(chē)正常運(yùn)行時(shí)，掛入空擋，則，汽車(chē)高速行駛，帶動(dòng)變速箱內(nèi)的部分部件高速運(yùn)轉(zhuǎn)，而發(fā)動(dòng)機(jī)怠速運(yùn)轉(zhuǎn)。

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，自動(dòng)變速箱的油泵也以發(fā)動(dòng)機(jī)的怠速轉(zhuǎn)速運(yùn)轉(zhuǎn)，由此產(chǎn)生的液壓壓力和潤(rùn)滑壓力（散熱）或者稱(chēng)流量，不足以供應(yīng)自動(dòng)變速箱內(nèi)高速運(yùn)轉(zhuǎn)部件的潤(rùn)滑或散熱，后導(dǎo)致變速箱因散熱不足使得內(nèi)部離合器燒損。

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，一般影響不大，不至于車(chē)毀人亡（有特殊情況的另言）。對(duì)變速箱而言，偶爾的超短時(shí)間N檔，不會(huì)有什么影響，長(zhǎng)時(shí)間（也可能十多分鐘）就會(huì)導(dǎo)致打滑燒片！燒片后的處理方法：大修變速箱。

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.
