车很少用到N挡?那你的变速箱可能会有问题!

The car rarely uses n gear? There may be something wrong with your gearbox!
对于自动挡汽车来说,很多人认为变速箱上的N挡没什么卵用,因为他们平时开车很少用到N挡(空挡)。驻车时基本都是直接挂到P挡,而等红灯时要么是挂P挡,要么是D挡+刹车,很少有人会挂入N挡,因为绿灯亮后再挂回D挡比较繁琐、浪费时间,不如一直保持在D挡上,一旦绿灯亮了直接松开刹车就能走······然而,汽车工程师不是傻,既然设计了N挡,就一定有它存在的道理。事实上,对自动变速箱的保护就是N挡存在的非常大的意义。下面就来给大家介绍一下自动变速箱上的N挡在我们日常用车中都有哪些作用:
For automatic cars, many people think that n gear on the gearbox is useless, because they rarely use n gear (neutral) when driving. When parking, they basically shift to gear P directly. When waiting for a red light, they either shift to gear P or gear d + brake. Few people will shift to gear n, because it is cumbersome and waste time to shift back to gear d after the green light is on. It's better to keep in gear d all the time. Once the green light is on, they can go by releasing the brake... However, automotive engineers are not stupid. Since they have designed gear n, There must be a reason for its existence. In fact, the protection of automatic transmission is of great significance for the existence of N gear. Now let's introduce the role of N gear on the automatic transmission in our daily vehicles:
驻车时N挡的作用
Function of gear n during parking
很多朋友在停车场停车时,一旦将车停入车位后,无非就是两种做法:1、先挂P挡,再拉手刹(或电子手刹)走人;2、先拉手刹(或电子手刹),再挂P挡走人。其实这两种做法在一定程度上都比较损车。对于这一种做法而言,因为自动变速箱的P挡都带有锁止功能,也就是说车辆内部会有一个卡子扣住变速箱的齿轮来让车达到静止的状态。如果是先挂入P挡再拉手刹的话,那么车辆停止时所受到的拉扯力基本都作用在了变速箱的齿轮和卡子上,长期下去会对变速箱的齿轮造成磨损,缩短变速箱的使用寿命;而如果是像二种做法那样先拉手刹再挂P挡的话,在平地还好,变速箱齿轮和卡子受到的拉扯力会小很多,基本都作用在了手刹系统里的钢丝拉线上了。
When many friends Park in the parking lot, once they park their car in the parking space, there are only two ways: 1. First shift to gear P, and then pull the hand brake (or electronic hand brake) to leave; 2. First pull the hand brake (or electronic hand brake), and then shift to p gear to leave. In fact, these two practices are more damaging to the car to a certain extent. For this approach, the P gear of the automatic transmission has a locking function, that is, there will be a clip inside the vehicle to fasten the gear of the transmission to make the vehicle reach a stationary state. If you first shift into gear P and then pull the handbrake, the pulling force received when the vehicle stops basically acts on the gears and clips of the gearbox, which will cause wear to the gears of the gearbox and shorten the service life of the gearbox in the long run; If you pull the handbrake first and then shift to gear P as in the second method, it's OK on the flat ground. The pulling force on the gearbox gear and clip will be much smaller, which basically acts on the steel wire cable in the handbrake system.
但如果地面不平是个斜坡的话,汽车向坡底下溜的那个惯性冲力不光会使手刹系统中的钢丝拉线受力加大,也会在一定程度上增加变速箱齿轮和卡子的咬合力,这样依旧会对手刹系统和变速箱齿轮造成磨损。所以,此时N挡的作用就显现出来了。自动挡汽车在停车时的原则是:不论什么地形,一定要先让车自己找平,这样停车时才能大程度地减小变速箱齿轮和钢丝拉线所受的拉扯力。而要达到找平的效果,使用N挡是很有必要的。因此自动挡汽车正确的做法应该是:停车踩住刹车――挂入N挡――松开脚刹车――拉手刹(或电子手刹)――进P档――熄火走人。
However, if the ground is uneven and it is a slope, the inertial impulse of the car sliding towards the bottom of the slope will not only increase the stress on the steel wire stay wire in the handbrake system, but also increase the bite force of the gearbox gear and clip to a certain extent, which will still cause wear to the handbrake system and gearbox gear wheel. Therefore, the role of N gear appears at this time. The principle of automatic car parking is: no matter what terrain, the car must level itself first, so as to greatly reduce the pulling force on the gearbox gear and steel wire cable. To achieve the leveling effect, it is necessary to use n gear. Therefore, the correct way for an automatic car should be: stop and step on the brake - shift into gear n - release the foot brake - pull the hand brake (or electronic hand brake) - enter gear p - stop and leave.
等红灯时N挡的作用
Function of N gear when waiting for red light
在诸如等红灯或临时停车等人这样的短暂停车时,很多人要么就是D挡+刹车,要么就是直接挂P挡。在这里,小编要提醒大家一点,无论怎么样,短暂停车时不要挂P挡。因为挂入P挡,变速箱的齿轮就会跟卡子相互咬合住,如果此时后方冷不丁的给你来个追尾,力度大点会直接把你的变速箱顶烂,即便力度轻也会顶断你变速箱的齿轮,那样维修起来不光麻烦,费用也很昂贵。
In such short-term parking as waiting for a red light or temporary parking, many people either shift to D + brake or directly shift to P. Here, Xiaobian would like to remind you that no matter what, don't shift to p gear when stopping for a short time. When you shift into gear P, the gear of the gearbox will bite each other with the clip. If the rear is cold at this time, you will have a rear end collision. If the force is strong, it will directly top your gearbox. Even if the force is light, it will break the gear of your gearbox. In that way, maintenance is not only troublesome, but also expensive.
如果在等红灯(或临时停车等人)时,一直保持D挡+刹车的话,变速箱并没有切断发动机与车轮之间的连接,这样不光没有降低发动机的负荷来达到省油的目的,发动机的振动也会很清晰地传递到车内,带动车厢一起轻微震动。因此,我们在短暂停车时,如果停车时间超过30秒,方式式是挂N挡+拉手刹(防止在不平的地面车辆出现溜车现象)。当然,对于有Auto Hold自动驻车功能的汽车来说,由于Auto Hold功能可以使车辆在短暂停车时自动启动四轮制动,即便在D挡或N挡你也无需一直脚踩刹车或使用手刹,车子始终处于静止状态。因此,这时候可以不挂“N”挡,直接挂“D”挡也是可以的。
If you keep D gear + brake when waiting for a red light (or temporary parking, etc.), the gearbox does not cut off the connection between the engine and the wheels, which not only does not reduce the load of the engine to save fuel, but also the vibration of the engine will be clearly transmitted to the car and drive the car to vibrate slightly. Therefore, when we stop for a short time, if the parking time exceeds 30 seconds, the mode is to engage gear n + pull the hand brake (to prevent the vehicle from sliding on uneven ground). Of course, for vehicles with auto hold automatic parking function, because the auto hold function can automatically start the four-wheel brake when the vehicle stops for a short time, you don't need to step on the brake or use the hand brake all the time even in gear d or N, and the vehicle is always stationary. Therefore, it is possible not to shift to "n" gear at this time, but to shift to "d" gear directly.
