What's the meaning of the gear in the car?

P stands for park gear, R stands for reverse gear, N stands for neutral gear and D stands for forward gear. Let's introduce these gears:

1, p file. That is, parking gear and parking gear, the mechanical device in the gearbox is used to lock the rotating part of the car. Only when the car comes to a complete stop can P gear be used, and the car must be in P gear when it is turned off.

2.r file. Reverse gear, as the name implies, is to shift gear when reversing. It should be noted that under the condition that the vehicle is not completely stopped, do not forcibly shift the R gear, which will cause the transmission to wear.

3.n file. Which is neutrality. Generally, when parking for a short time, there will be a neutral position. At this time, your right foot can leave the brake pedal to rest. But if it's uphill or downhill, you still need to step on the brakes, otherwise it will slip, unless you pull the hand to brake the electronic brake.

4.d file. In the forward gear and drive gear, when shifting into the D gear, the driver only needs to control the accelerator pedal to control the vehicle speed, and the transmission will automatically determine the gear according to the accelerator size and vehicle speed without manual gear shifting.

Extended data:

There are two main forms of automatic transmission used in automobiles. One is a step automatic transmission, and the other is a continuously variable transmission (CVT). The most commonly used mechanical CVT in automobiles uses V-shaped metal belt or transmission chain to transmit torque in the V-shaped grooves of driving wheels and driven wheels. This transmission mode is usually used for smaller vehicles.

When a modern automatic car is driving, the driver only needs to control the accelerator pedal, and the computer analyzes the engine accelerator opening and speed signals picked up by some sensors, so as to automatically control the speed change or shift the transmission into different gears to work. Generally speaking, the automatic transmission will lose the power of the engine.

The biggest advantage of automatic parking is convenience, especially when there is traffic jam, especially when the traffic jam is uphill. At present, automatic transmission is becoming more and more popular. From the perspective of advanced countries, most vehicles have transitioned to automatic transmission, and it is the trend of automobile development that automatic transmission replaces manual transmission as the main vehicle type for daily driving.

People's network-control automatic cars pay attention to these points!
