Automatic transmission: If the car is parked for a long time without a handbrake, you only need to h

This is not a big problem, provided that the engine is turned off and the power supply is cut off, so that the gearbox does not have any original working, and it is naturally okay in that gear. There is also the handbrake to be able to brake to prevent rolling, because the vehicle can move in any gear out of the P gear. Of course, for the sake of safety, you still have to hang the gear to the P gear, and you don't have to be afraid to forget, all automatic vehicles, the gear is not in the P gear, and the key cannot be pulled out.

First of all, we must understand what it is all about hanging a p-gear. In terms of mechanical action, it can't be compared to the engine. Hanging the P gear is actually the transmission using a "hook" to hook a part of the output end of the transmission.

This part is definitely not one of those high-precision transmission gears, and the precision required for this part is not high, generally a wheel (parking gear) with a card slot. The hook (parking pawl) is hooked to this card slot. After we hook up the P gear, it is through this hook that the card slot is engaged, so as to lock the transmission part of the car.

Because there is a gap between the hook and the card slot, if you step on the brake to hang the P gear, when the brake is released, the vehicle will shake back and forth until the hook is stuck at one end of the card slot, and the eating force will not move. It is precisely because of the last shake of the car that you will think that it "hurts the car".

And if you brake first, pull the handbrake up, the vehicle is completely stationed, and then hang the P gear, naturally there will be no shaking at the last moment. If the last shaking of the car is actually quite slight on a flat road, for a large piece of metal parts, that small impact is simply a floating cloud.

How did the gear get stuck? This is because when the car is parked on a slope, if the handbrake is not pulled and the brake is released, then the force of the car sliding down is concentrated on the card slot and hook, and the card slot and hook will bite very tightly and are not easy to be separated. Therefore, at this time, if you hang other gears, you will feel that the resistance to trigger the gear lever is relatively large.

If the slope is larger, there will be a situation where you can't hang the gear, which is caused by loosening the brakes in advance.

As long as we understand the structure of the P gear, and strictly follow the brakes, the car stops and then does other things, at this time, the P gear or the handbrake is pulled first, there is actually no impact on the car, according to personal habits to operate, there is really no need to worry about this problem. Of course, if you still have a little obsessive-compulsive disorder, then you should pull the handbrake first, and then hang the P gear.

The Mercedes C-Class has the handbrake at the bottom, in the left foot position.

Wooden with a handbrake? Let's be there at the foot.

There is harm. As we all know, automatic transmission is more and more due to the ease of operation and the fact that it has been reduced to parity. In addition to some car lovers who prefer to control the driving feeling, they will also favor manual transmission, and one of the major standards for most friends to buy a car is automatic transmission.

But many people have not seriously studied the operation of the automatic transmission, so there is a behavior of parking directly hanging the P gear without pulling the handbrake, and today I will talk to you about the harmfulness of this operation.

The automatic transmission eliminates the tedious shift switching of manual transmissions, and the transmission can automatically adjust the gear ratio according to the vehicle speed, thus simulating the output of different gear ratios of the manual transmission. Speaking of the handbrake alone, because the manual transmission does not have a P gear, the step of parking is generally to return to the N gear, and then pull up the handbrake. The P gear of the automatic transmission car has a parking function, and the locking function can be realized on the flat ground normally, but parking on the ramp will damage the vehicle somewhat.

The P gear in the automatic transmission is the parking gear, the main function is to lock the gearbox, when the vehicle is parked, if the vehicle has a forward or backward movement tendency, the P gear can provide a reverse resistance by locking the gearbox, which is commonly known as "suffocation", so that the vehicle can not move. But this reverse force is limited, once the external force is larger, it will break the gears of the gearbox, so as to overhaul the gearbox. Occasionally, of course, it is not a big problem, but in the long run, it will inevitably greatly reduce the life of the gearbox.

Handbrake can be said to be an important line of defense to protect the safety of the vehicle, first of all, the braking force of the handbrake acts directly on the hub, and the force is much greater than the braking force brought by the P gear, and secondly, the handbrake structure is simple and the effect is good, so each vehicle is equipped with a handbrake function. Today's cars often use electronic parking brakes, which work the same as manual, but change the original manual operation to an electronic system.

Parking in this way will definitely have a certain amount of damage to the car, and may even reduce the life of the car, and will also cause some damage to your own engine.

There are injuries, and doing so can easily make the car's brakes, engine, and then various parts of the car will be affected.

It is harmful, so that the parking is not particularly stable, it is likely to cause some accidents, and the impact is relatively large.

There is a certain risk that the car is only in P gear and does not pull the hand brake, especially when parked on a slope, there is a possibility of slipping. And the hand brake is made.

When you want to park, if you are an automatic car, and there is a P gear in it, then you can't only rely on the P gear to park, because it is usually just a parking function, although it can stop the car, but if there is no handbrake, it will bring great harm to the car.

1. Only hanging the P gear without pulling the handbrake will shorten the service life of the gearbox.

According to the current relevant research, a good gearbox, under the condition of reasonable operation, can be used for at least 5 years. If you only hang the P gear when parking, and do not pull the handbrake, the P gear has no handbrake effect, and it will hurt the gearbox in the long run, resulting in a shortened service life of the gearbox, so you must pay attention to the handbrake. <>

Second, hanging the P gear without pulling the handbrake will hurt the gear.

However, there are many car owners who have such an experience, that is, when they park on the slope, they hang the P version, but forget the handbrake, at this time, they will obviously feel that the car slides forward on the slope, and sometimes this situation will cause traffic accidents.

In addition, on the slope, only the P gear does not pull the handbrake will also cause the gear to bite very tightly, if you want to start the car again, then you need to spend a lot of effort to shift gears, after shifting gears will also cause the gears to produce a relatively large impact, and even sometimes make some abnormal sounds. Therefore, long-term hanging the P gear without handbrake will hurt the gears. <>

3. Correct parking method.

After understanding that the parking method of only hanging the P gear without pulling the handbrake is incorrect, it is necessary to learn the correct parking method in order to extend the service life of the car and protect the various components in the car. To some extent, this can also reduce the financial loss of the car owner. <>

The correct way to park is when you want to park, first observe whether the surrounding environment is suitable for parking, if it is suitable for parking, first hang the N gear in the car, then pull the handbrake, and finally hang the P gear, so that you can extend the service life of the car.

No, a handbrake is required to prevent the car from moving on its own, or from having a car accident.

It is possible to do without, because the P gear is a mechanism with brakes, and it is parked directly on the P gear, which is very easy to use.

Although there is a P file parking, but also need a handbrake, if there is no hand brake, only P file parking, very inconvenient and very dangerous.

It is not necessary to handbrake to prevent the car from moving on its own, or in an environment where there is a car accident.

For automatic transmission models, under normal circumstances, the owner will use the P gear to park, and for this P gear to park, it is necessary to use the handbrake. Because the P gear is attached to the gearbox gear, although the car will not slip away without pulling the handbrake, it is easy to cause damage to the gearbox for a long time, thereby increasing the maintenance cost of the owner.

1. The handbrake needs to be pulled up when the car is parked and hooked into the P gear.

The so-called P gear is the parking gear of the car, and for the automatic transmission model, you must hang the gear in the parking when parking, and then pull up the handbrake, if you don't do this, it is very easy to damage the gears of the car gearbox, and pull the handbrake can also play a double insurance role, so that your car will not slip when parking into the uphill and downhill sections. <>

2. When can automatic transmission models be put into P gear?

I believe that there are a lot of automatic car drivers do not know very well which stage of the car parking lane to park, for the general automatic transmission model, when parking, first step on the brake, and then hang the car into neutral, hang into neutral and then pull up the handbrake, and then turn off the car, and finally you can hang the gear in the P gear, this parking method is the most standard, and at the same time will not let the car gearbox be damaged, but also can effectively extend the service life cycle of the car gearbox, So when we pull the handbrake, the car can be put into P gear when the engine is turned off. <>

3. Summary. For automatic transmission cars have P gear, you need to pull the handbrake after parking, because there are two benefits to this, the first benefit is to effectively protect the gears of the car engine, and the second benefit is to add double insurance to the car, so that your car will not slip. Therefore, the majority of car owners must hold the handbrake when parking the car, especially when parking on some steep slopes, not to mention automatic transmission models, even manual transmission models need to be hung into gears, and the purpose of this is to prevent accidents caused by car rolling.

Of course, you also need to use a handbrake, especially on uneven roads, and it is best to use a handbrake to prevent rolling.

Need! Now most of the automatic transmission cars are electronic handbrake, when parking, first hang into neutral gear, in the hanging p gear, this is the parking gear, and finally pull the handbrake, develop a good habit, can protect the gearbox well.

When the automatic transmission car is parked, although it is blocked, try to choose the handbrake, and after pulling the handbrake, the car can be parked more smoothly.

I think that in special cases, handbrakes are still needed, because handbrakes are more convenient, safer, and widely used in life.

No. D is for the driving gear. The P gear refers to the parking gear, which allows the braking system to bear most of the force before finally engaging the P gear.

When parking for a long time, the pure first coincidence is still in D gear: When the vehicle equipped with an automatic transmission is stuck in traffic, some owners often only press the brake pedal, but the gear lever remains in D gear (driving gear) and does not change gears. This is allowed if the time is short.

However, if the parking time is long, it is best to shift into N gear (neutral) and tighten the parking brake.

Because the gear lever is in D gear, the automatic transmission car generally has a slight forward movement, if you step on the brake pedal for a long time, etc., the key is used to forcibly stop this forward movement, so that the transmission oil temperature rises, and the oil is easy to deteriorate, especially when the air conditioning system is working, the engine idle speed is higher and more unfavorable.

As long as the car does not move", if you want to move after parking, you must first tighten the handbrake, otherwise it can only be done on a very flat road, many places such as the mountain city of Chongqing slopes to find a flat parking is sometimes more difficult, so before parking and turning off whether it is P gear off or N gear off, it is particularly important to tighten the handbrake before releasing the foot brake.

For automatic transmission, it is not necessary to pull the handbrake first, and then hang the P gear for parking, because this parking will soon cause the gears of the internal structure of the gearbox to wear, so that the gearbox working condition will deteriorate. The correct way to park in automatic transmission should be to first hang neutral, then pull the handbrake, then turn off, and finally hang up the P gear, which is the correct way to park the automatic transmission model. <>

In fact, many people now have their own cars, and many of them are automatic transmission models, because now the city roads are more congested, commuting cars are very frequent, so many people choose to buy automatic transmission models, and do not choose manual transmission models, if manual transmission models encounter urban road traffic jams, it will be very troublesome, and automatic transmission models will not exist this problem, so many people like to buy automatic transmission models. <>

But for the driver friends who have automatic transmission models, they only know how to drive the car, and do not know how to park the automatic transmission model, I said above first hang neutral, then pull the handbrake, and then turn off, and finally hang the P gear This way is very correct, because this does not damage the engine gearbox, but also can make the working condition of your car gearbox better and better, if you first pull the handbrake and then hang the P gear, it is easy to cause damage to the internal structural parts of the gearbox, In this way, it is easy to shorten the service life cycle of the car gearbox, and if it stops like this for a long time, it will also lead to obvious frustration when the gearbox is in gear, giving people a very bad driving feeling. <>

With the development of our society and the rapid advancement of the economy, many people have enjoyed the convenience brought by the car, but have a certain car knowledge, I think it is very necessary, such as the way of parking, as long as you learn how to park the car, this can not only make you have a better driving experience, but also make your car accessories longer life, thus reducing their own economic costs, so it is important to understand the common sense of the car.
