What does R stop N stop D gear mean?

The meaning of R block N gear D gear is as follows:

1. R file. R gear is also an automatic car.

Using more gears, it is the reverse gear of the automatic transmission car, when we need to reverse into storage.

When parking on the side, R gear is our best helper.

2. N files. This gear is the neutral of the automatic transmission car. When we need to stop for a short time, such as waiting for a traffic light, we can put the gear into N gear, so as to avoid the engine pressure caused by the car pressing the brakes for a long time.

3. D file. D gear is a gear that most people will only use, accelerating and stepping on the accelerator, slowing down and applying the brakes, it seems very simple, but this driving method still needs to be changed a lot.

Other gears mean.

1. L file. L gear is the low-speed gear of an automatic transmission car when we are driving on dirt or need strong traction.

When going up and down steep slopes, the L gear is our best helper.

2. S file. S gear is the sporty gear of an automatic transmission car, and when you engage S gear, the car is able to explode with more powerful acceleration.

Give you a better operating experience! When you're stuck in traffic or driving at high speeds, S gear is much easier to use than other gears.

3. P file. P gear is the parking gear of automatic transmission cars, which is often used when we park, but we must remember that during the parking process, we must wait until the speed of the vehicle is reduced to zero before we can hang on to P gear, otherwise it will be harmful to the car.

The R gear is the reverse gear, which is the same as the reverse gear of the manual gear, and is used when reversing. The n-gear is neutral, which is the same as the neutral gear of a manual car, and is used for short stops. D gear is the forward gear, which is used when the car is moving forward.

l is a low-speed forward gear, which is equivalent to the first and second gears of a manual car. This gear can be used when going uphill to allow the car to pass more traction; When going downhill, you can use the engine to control the speed of the car and prevent the brakes from getting hot.

It should be noted that the car can be hung with D and S from L gear. If the speed of the car is high, it cannot be put into L gear, which will cause an impact on the gearbox. S is for sport mode, and the throttle response is more positive when this gear is engaged, and it can be used when overtaking.

The d-position is the most commonly used driving position. It is important to grasp that since the automatic transmission determines the gear according to the size of the throttle and the speed of the vehicle, the speed of the vehicle when changing gears is different depending on the operation method of the accelerator pedal.

If you quickly press the accelerator pedal when starting, the upshift is late, the acceleration ability is strong, and after reaching a certain speed, the accelerator pedal is quickly released, and the car can be upshifted immediately, so that the engine noise is low and the comfort is good.

Another feature of the D position is that the forced low gear, which is convenient for overtaking at high speeds, and the accelerator pedal is quickly pressed to the end in the D position driving, and the forced low gear switch can be automatically downshifted, and the car accelerates quickly, and the accelerator pedal can be automatically upshifted after overtaking.

A car that uses a manual shift mechanical transmission (also known as manual transmission, MT) to adjust the speed of the vehicle. That is, the gear lever can be toggled by hand to change the gear meshing position in the transmission and change the transmission ratio, so as to achieve the purpose of speed shifting. When the clutch is pressed, the gear lever can be activated.

Compose. By switching different gear sets, the gear ratio can be changed. As a key link in the distribution of power, the gearbox must have two major parts, the power input shaft and the output shaft, plus the gears that make up the gearbox, which is the most basic component of a manual gearbox.

Principle. The power input shaft is connected with the clutch, and the power transmitted from the clutch is directly transmitted to the gear set through the input shaft, and the gear set is composed of gears of different diameters, and the power transmission effect achieved by different gear ratios is completely different.

P, N, D, and R are all automatic gears, of which P is the parking gear, N is neutral, D is the driving gear, and R is the reverse gear.

The details are as follows: 1. P parking gear.

When the parking is not in use, the gear position is here, and at this time the wheels are in a mechanical lock state, which can prevent skidding.

2. R gear reversing gear.

As the name suggests, it is used to reverse the car.

3. N gear neutral.

Use this unit when stopping temporarily, such as at a red light. Note that this gear means neutral. To prevent the vehicle from slipping on slopes, be sure to apply the brakes.

4. D gear forward.

Also known as drive gear. That's the time to move forward, using this device.

P file. It means parking stalls. When this gear is engaged, the parking locking mechanism locks the transmission output shaft.

R gear: It means reverse gear. When this gear is engaged, the hydraulic system is switched on.

Reverse gear oil circuit, so that the driving wheel reverses, reverse gear driving. When the vehicle is not completely stopped, do not force it to turn into "R" gear, otherwise it will cause damage to the transmission.

n gears. Meaning gap. When engaged in neutral, planetary gears.

The system idles and cannot output power.

D file. It means forward gear. When the shift lever is in this gear, the hydraulic system control device will automatically connect the corresponding forward gear oil circuit according to the throttle opening signal and the vehicle speed signal, and can automatically raise and lower gears with the change of driving speed to achieve automatic transmission function.

S gear: It means sport mode. When the shift lever is in this gear, the transmission control module receives the driver's instructions, and then the vehicle enters the sport mode, the shift logic will be more aggressive, and the gear changes will be more frequent, giving the driver a better sense of control and throttle response, which can reflect the driving pleasure of the vehicle.

Automatic principle:

The power of the engine is transmitted through the gearbox, which is also a key indicator of fuel consumption, and in general automatic transmissions.

The fuel consumption is more than 10% higher than that of manual transmission. It doesn't matter if it's manual or automatic.

The more gears, the more fuel-efficient.

The automatic transmission uses a planetary gear mechanism to shift gears, and it automatically shifts gears according to the degree of the accelerator pedal and the change in vehicle speed. The driver only needs to control the speed of the vehicle by manipulating the accelerator pedal.

Generally speaking, there are the following types of automatic transmissions commonly used in automobiles: hydraulic automatic transmissions, hydraulic transmission automatic transmissions, electric transmission automatic transmissions, stepwise mechanical automatic transmissions and continuously variable mechanical automatic transmissions.

The most common is a hydraulic automatic transmission. The hydraulic automatic transmission is mainly composed of a hydraulically controlled gear transmission system, which mainly includes two parts: automatic clutch and automatic transmission. It automatically shifts gears according to the opening of the throttle and changes in vehicle speed.

Nowadays, car lovers like to buy automatic transmission, and everything is simple to drive, and the automatic transmission car is more complex in configuration, and the cost of maintenance is higher, so you can't be too casual when you usually drive, especially the gear can not be used indiscriminately.

R gear is a reverse gearWhen the vehicle needs to reverse, we can put it into R gear for reversing, and we can only put it into R gear after the vehicle is completely stopped, if the car is not stopped, R gear will cause damage to the gearbox.

n gears. In fact, it is equivalent to the neutral gear of our manual transmission. When the Nth gear is engaged, the vehicle can coast. In the case of an automatic transmission, it is strictly forbidden to coast in N gear, which has a great impact on the engine and transmission, as well as driving safety.

D gear is also called forward gear or drive gearIt is the gear we use most often. When we need the vehicle to move forward, we can put on the D gear and drive the vehicle forward. When the vehicle is in D gear, it can automatically adjust the matching gear according to the engine speed and load, so that the vehicle can be kept within the corresponding speed range.

N gear precautions.

For example, when waiting for a red light or waiting for someone, if the parking time does not exceed 3 minutes, it is recommended to hang N gear and pull the handbrake. Don't forget to pull the handbrake, and you can keep stepping on the brake without pulling the handbrake.

Because it is easy to slip in neutral gear, it will also accidentally touch the shift handle and hang on the D gear, especially if there are children in the car and lie in the middle of the car to play, the child may touch the shift handle, and it is very dangerous to hang the D gear car by mistake and go forward by itself.

D is the most commonly used gear, which can be completed by throttle control when you need to raise or lower gears. n is neutral, temporarily stop and hook into this gear, stop the movement of the vehicle, and the power is not interrupted r is reverse gear, and the vehicle can only be engaged when it stops. Models with a lock button also need to press the button to switch.

1. When the vehicle needs to move forward or backward, select the D position or R position, and only push the gear lever from the low position to the high position until the D gear position, and it is strictly forbidden to pull from the high position to the low gear. It is strictly forbidden to use neutral coasting in driving (neutral coasting will cause poor lubrication of transmission actuators, or even serious damage).

2. When reversing the automatic transmission vehicle, ensure that the vehicle is stopped steadily and then put into the R gear reversing.

3. When starting the automatic transmission car, pay attention to ensure that the gear is on the P or N gear. Failure to do so will damage the gearbox.

4. When the transmission is abnormal or the fault indicator is lit, please stop using it immediately and overhaul it.

5. When the automatic transmission car cannot be started, it cannot be manually pushed or dragged by other vehicles, otherwise the vehicle will be seriously damaged. Professional towing personnel and specialized vehicles should be found.
