What's the use of the car's idle gear?

Idle gear is generally used for towing, waiting for red lights, gliding in idle gears, and when changing gears and stopping during driving.

Idle gear means that the gearbox is not working and is idle, and driving needs to be geared, so that the gearbox can travel at different speeds.The idle gear does not have a watch to turn off the engine. When the engine is turned off, the engine is not ignited, and the whole car is in a state of no operation.

As the name implies, it is used for reversing. When the vehicle is stationary and the engine is idling, it can only be in this gear. Note: The car must not use R gear when moving forward, and pay special attention to the control of the accelerator pedal when reversing.

The function of automatic transmission N gear (idle gear): When the towing vehicle needs to be repaired or temporarily towed for other reasons, the gear must be hung in N gear. Temporary parking The vehicle needs to be temporarily parked. When it does not take a long time, you can park by hanging the N gear.

Idling is to disconnect the power connection between the engine and the gearbox, so that the engine and the state of idling, and the motor vehicle stops for a long time or temporarilyIt is used when parking. If the vehicle is damaged and cannot be driven, whether it is an automatic transmission or a manual transmission model, you need to move the gear to the idle gear.

The difference between idle gear and parking gear

1. The letter represented by idle gear is: N, and the letter represented by parking gear is: P. When parking, there is a gear bite in the gearbox, which can be used for parking and can help the vehicle brake;When in idle, the transmission lever of the motor vehicle is not put into any forward or backward gear, and the gearbox and the drive wheel are completely separated.

2. When using the parking gear (P gear), the gearbox is bite and has a braking effect. On the road with a small slope, the purpose of parking can be achieved without a handbrake. And hanging on the idle gear (N gear), the gearbox gear is away. As long as there is a slope, the car will slide.

3. The N gear is the idle gear, the P gear is the parking gear, and the parking gear is equipped with handbrake, and the car is prohibited from moving. Automatic transmission, as the name implies, means that the driver does not need to manually shift gears. The vehicle will automatically select the appropriate gear according to the driving speed and traffic conditions.

4. Different types, P gear is called parking gear, and N gear is called idle gear. Different functions. P gear is suitable for parking and parking, while N gear is used for short-term parking.When the clutch controls different P gears, the parking gear is partially locked in the gearbox, so if you don't step on the brake on the flat ground at this time, the vehicle has a certain parking effect.

How to use the idle gear of the automatic transmission

1. The role of the automatic transmission N gear: When the trailer vehicle needs to be repaired or temporarily towed for other reasons, the gear must be hung in the N gear to proceed. Temporary parking The vehicle needs to be temporarily parked. When it does not take a long time, you can park by hanging the N gear.

2. The use of the automatic transmission gear is that the automatic transmission car needs to step on the brake and press the button on the gear handle before moving the gear lever, pulling back, and stopping to the required gear. The gear is generally displayed on the instrument at the same time.P gear parking gear, R gear reversing gear, D gear forward gear, S gear sports gear, L gear low speed gear.

3. How to use the automatic neutral gear correctly. Under the condition of safety, any other forward gear can be moved to N gear at any time, but you need to brake from P and R gear to N gear first.

4. The mechanical button on the transmission lever can be used to shift gears when the automatic transmission is out of power; all automatic transmission models will have a shift button, which can be used to change gears even if there is no power.

Explanation of automatic transmission gear

The explanation of automatic transmission gear is as follows: D gear: This is the most commonly used gear of automatic gear models. There are usually three types of DDD3, similar to the 1 and 2 swing, 3 and 4 gears, 5 and 6 gears of manual transmission. Different types of gears do not need to be controlled manually, and the car will move up and down according to the adjustment of the throttle.

Low-speed gear Low-speed gear is the third gear of automatic transmission vehicles, which is selected when climbing hills or passing through muddy roads. This gear will increase the engine speed, so that the vehicle can provide more torque and power output.

Automatic transmission has P gear, R gear, N gear, D gear, S gear, m gear and L gear respectively.

Automatic car gears include P gear, R gear, N gear, D gear, S gear and L gear. P is Parking. After the car stops, the P gear vehicle is to brake to prevent movement. Unlike N gear, P gear interrupts the power output. At present, some models will have independent P gear, which is called electronic braking, and the principle is the same.
