The automatic transmission is divided into P, Parking N, Neutral ?

Hello! The automatic transmission gear is divided into P parking, (R reverse), N neutral, and (D forward).

Automatic transmissions are available in P, R, N, D, or L gears.

1. P (parking): used for parking, it is the use of mechanical devices to lock the rotating part of the car, so that the car can not move. When the car needs to stay in a fixed position for a long time, or before leaving the vehicle after stopping, the hand brake should be applied and the paddle lever should be pushed into the "P" position.

It is important to note that the vehicle must not use the P gear until it is completely stopped, otherwise the mechanical part of the automatic transmission will be damaged. In addition, the automatic transmission car - [device neutral start switch, so that the car can only start the engine in the "P" or "N" gear, so as to avoid the car suddenly moving forward when starting in other gears.

2. R (reverse): reverse, the vehicle is used to reverse. It is usually necessary to press the safety button on the lever to move the lever to the "R" position.

It should be noted that when the vehicle has not completely stopped, it is absolutely not possible to force the vehicle to turn into "R" gear, otherwise the transmission will be seriously damaged.

3. N (neutral): neutral. With the paddle in "n" gear, the power between the engine and the transmission has been cut off and separated. For a short pause, you can place the paddle lever in this gear and pull the hand brake lever, and take a break with your right foot off the brake pedal.

4. D (drive): forward gear, used for general road driving. Due to the different designs of different models, the "D" gear generally includes from 1st gear to high gear or 2nd gear to high gear, and will automatically change gears due to changes in speed and load.

By placing the paddle lever in "D" gear, the driver can control the speed of the car as long as the accelerator pedal is controlled.

Second gear): 1st gear is the forward gear, but the transmission can only be converted between 1st and 2nd gear, and will not jump to 3rd and 4th gear. By placing the paddle in 2nd gear, the car will start in 1st gear and will automatically turn to 1st gear when the speed increases.

The advantage of this gear section is that when going up or down, the vehicle will be stably in the 1st or 2nd gear position, and the transmission will not be constantly shifting due to the load of the incline or the unbalanced speed. When descending on a slope, braking with the resistance of the engine at low revs will not make the car go faster and faster.

First gear): 1st gear is also a forward gear, but the transmission can only work in 1st gear. You can't change to a different gear.

It is most useful in situations of severe traffic jams and on slopes with large slopes. When going up or down a slope, you can make full use of the torsion of the car engine.

7. The L gear is a slow gear, which is used when running on steep slopes.

The automatic transmission gear is divided into P parking, R reversing, N neutral, and D driving gear.

Hello automatic transmission gears are divided into P parking gears. rReverse. N neutral. D-gear running gear. Hope mine can help you, thanks.

Hello, according to your description, the automatic transmission gears are divided into P Parking, R Reverse, N Neutral, D Forward Gear, Hope, Thank you.

The automatic transmission gear is divided into P parking, also known as parking gear; r Reverse; n Neutral; d. Automatic driving gear; In addition, there are also automatic transmission models with S for sport mode; 1 is 1 gear; 2 is 2 gears.

The automatic transmission gear is divided into P parking, (D reverse), N neutral, (R drive).

Automobile automatic transmission only D front gear, R reverse, N neutral three gears N neutral, in fact, we often say that P parking gear and N gear are the same, are neutral gears, but on the cornerstone of neutral gear to improve a set of parking control effect.

What other gears are available for automatic transmissions?

From the point of view of operating habits and ergonomics, it is more common for cars to change between P gear and use. It is also a very common control method to go from N to D when starting and from D to N when parking. In the early stage, the gearbox is in D gear, usually with D3, D2, D1, S, L and other gears, which is naturally unlikely to be separated from D gear and rationally arranged, so the D gear scheme is designed in the position closest to the human body.

Finally, let's talk about the position of the nth gear. The aforementioned P and N gears are actually neutral gears. Comparatively speaking, the P gear adds a set of parking mechanism control, which means that the P gear is only used for parking and long-term parking, and the application frequency is the lowest, so put him on the top to bypass the driver's position.

Why are car automatic transmissions represented by letters?

Since automatic transmissions were invented by Americans, they were mainly used in the United States in the early days. When the Americans turn off their phones, it is usually not easy to reverse into the garage and can only immediately drive in the right direction. When the car is running again, the P gear is running, immediately pull the R gear, and then engage the D gear to drive slowly.

The thinking logic of this operation process is also in line with the thinking logic characteristics and ergonomic habits of Americans. So the P-stop is placed at the top, and the final conversion order is PRND.

With the development trend of automatic automatic control system of automobile transmission, the gear control of automatic transmission has long been keyed by electronic components, and the gear sequence has long been unrelated to the position under the control of electronic components thinking logic, and the automobile company can match and install in accordance with other sets of sequences, but taking into account the customer's operating habits and agreed conventions, the order of PRND is stored.

Because when arranging, it is arranged according to people's usage habits, P gear is used when the car is stopped, R gear is used when reversing, N gear is neutral, and D gear is used when moving forward.

The automatic transmission is set in a total of 4 gears, which is to adapt to different road conditions. In a car with an automatic transmission, these gears can be switched freely.

Because this order is very simple and clear, and it can also be remembered clearly by car owners, this order is also regular.

With the development of science and technology, the manual wave car has been full and gradually replaced by its own car, the reason is that the automatic transmission car is simple and fast to drive, and the traffic jam does not need to step on the clutch frequently, and the driving is easier, so the problem comes, how to understand the P gear, R gear, N gear, D gear, and L gear of automatic transmission? Here are a few points to make it easier for everyone to remember:

P gear: Parking, Parking.

Usage scenario: When the vehicle needs to be parked for a long time or temporarily, the gear should be switched to P gear to avoid rolling.

R gear: Reverse.

n-gear: Neutral

N gear is to cut off the link between the car gearbox and the engine, N gear use precautions: switch to N gear need to keep your feet on the brakes, so as not to cause front and rear slippage, and automatic transmission of the car is not recommended N gear, that is, neutral sliding, so as not to cause clutch damage caused by the speed difference between the engine and the gearbox.

D gear: Forward gear

Switching to D gear when the car is moving forward, this goes without saying. Note: Do not switch to N gear until the vehicle has not been stopped.

L Gear S Gear: Sport mode (S is marked on some models).

L gear can be regarded as a downshift acceleration device, the car needs to overtake action, when accelerating sharply, switch the gear to L gear, step on the accelerator deeply, the car will reduce the gear, increase the engine speed, to achieve a downshift acceleration function.

M (+): Manual mode

Some models have a mark marked M (+), which means that your car supports manual driving mode, that is, manual operation of adding and decreasing gears, switching to sports mode when switching the gear knob to M gear for the first time, in this mode, switching the gear handle up or down, the car automatically enters the manual mode, and only needs people to judge the up (plus one gear) and down (minus one gear) during the driving process, and switch back to D gear to automatically cancel the manual mode.

P gear represents parking, R gear represents reversing, N gear represents neutral gear, D gear represents exercise, and L gear represents low-speed driving.

They are parking, reverse, neutral, forward, and low-speed gears, and each gear represents a different speed, which can be reasonably controlled.

The P gear of the automatic transmission car is the parking gear, the D gear is the forward gear, the N gear is the neutral gear, the R gear is the reverse gear, and the L gear is the climbing gear.

They represent parking, reverse, neutral, forward, and crawling, which are some of the basic operations of automatic transmission vehicles.

The P gear is the parking gear, the N gear is neutral, the D gear is the reverse gear, and the R gear is the driving gear. （）

a.That's right. b.Mistakes are pure mistakes.

Correct answer: B

This is entirely from a security point of view.

All countries and all manufacturers of the draft Huai automatic transmission models are designed in the order of prnd, whether you use the shift lever, or the gear, or the rotary button shift, or the way of the button, this sequence logic is fixed, they are basically the key to take a similar logic, but in fact, the safest design is the shift lever.

Of course, these new set-up meters will also take into account some of the safety hazards that may be caused by the aforementioned misoperation.

Why does N-buffering and splitting have to be between R (reverse) and D (reverse)? The shifting of the automatic transmission is by hydraulic shifting, and the hydraulic reversal of forward D and reverse R. In order to protect the mission's planetary gears, the N gear acts as a buffer between the D and R gears.

In other words, if you change from D to R, or from R to D, you can use N . The oil pressure is zero in the n gear and then switch to the next gear. When transitioning directly from D gear to R gear, the transmission may be damaged due to the natural collision of two opposite hydraulic pressures, which may lead to damage to the mechanical structure in severe cases.

In addition, the n-block also has a splitting effect that separates D and R. If d and r are neighbors, misoperation may occur when attaching files. I wanted to hang d but accidentally hit R, what a tragic thing.

I wanted to move forward, but I didn't expect to go back and hit the wall, and I felt embarrassed. So the r and n gears are in the middle. The top P gear is mechanically locked.

This is the use of a mechanical device to lock the transmission part of the car so that the car cannot move. The car needs to stay in a certain position for a long time, or before leaving the vehicle bridge after stopping, it should brake well and push the tie rod into the "P" position. It is important to note that P gear is used when the vehicle comes to a complete stop.

Otherwise, the mechanical part of the automatic transmission will be damaged. In addition, the P gear can prevent the shift operation on the drive from giving way to the wrong gear, prevent the driver from shifting the shift position to the P gear while driving, and at the same time, the R gear is slow, and hanging in the P gear will not have a big impact on the transmission. If you get into P gear while moving forward at high speeds, the transmission may break.

At the same time, we often need to reverse the car into the garage when parking, and hang the P gear after reversing to complete it in one go. Currently, some models have knob rods designed in the form of knobs, but they are also arranged in the order of PRND. The D file closest to you is the most used D file in normal operation, so the natural D file is closest to you.

In addition, when using P and D gears, the vehicle is generally stationary, so you can safely push the lever down or up. On the other hand, when using Minfeng N and R gears, the car is generally in a dumb state, and in the middle two gears, we generally carefully open the gears. Although I was afraid of deliberately installing the wrong gear, the P and D up and down could be pressed to the end, so I was not too cautious.

Automatic gear P, R, N, S, D, L, M**:

P - Parking, after the car stops, the vehicle is braked to prevent movement. At present, some models will independently go out of the P gear, called electronic braking, and the principle is the same.

R – Reverse, which can only be put into gear when the vehicle is stopped. Models with a lock button also need to press the button to switch.

n - neutral, temporarily stop and hook into this gear, such as waiting for a traffic light, and at the same time pull up the handbrake. Disable this gear when going downhill.

S - Sport, the difference between D gear and S gear is that the computer switches different shift programs, so S gear can be switched at any time, and there is no adverse effect such as damaging the transmission. It is suitable for overtaking and is not suitable for high-speed use.

D - Drive, the most commonly used gear, can be completed by throttle control when you need to move up and down gears. D1 (or L), D2, and D3 are equivalent to 1 and 6 of manual gears.

l - low-speed gear (low), when the vehicle is downhill, the low-speed gear is engaged to reduce braking; When the vehicle is going uphill, it will be more powerful to climb the hill when it is engaged in a low gear.

m - Manual mode, unique to the manual automatic model, can enjoy the fun of manual gear shifting. The "+" sign indicates an upshift, while the "-" sign indicates a downshift.

Lock button – press this button to enter the P position, R position, and to leave the P position. Specifically, when entering a gear that may cause a reverse shock to the transmission, it will be locked, and it will be unlocked by pressing the lock button when changing gears.
