Problems changing gears while driving? When should I change gears while driving?

My own experience: It feels good!

For example, our current speed is 50km h, see that there is a bend in front of us, start to slow down, slowly reduce the speed of the car, when the speed is about the same, step on the clutch, then the car is on the bend, that is to say, the car enters the bend, and then take off the high-end while hanging on the low gear to release the clutch and continue to move forward.

This makes sense.

Let me explain again: 1 Pay attention to the timing of stepping on the clutch, because at this time you are stepping on the brake to slow down, if you step on the clutch late, it is easy to stall because it is still in high gear and the speed is low.

2 Do not remove the gear before cornering, as it is not safe because the engine and transmission are separated.

3 is to press the next clutch to complete the steps of downshift and upshift.

This makes sense, and I hope you can learn it!

The exclamation mark at the front is to get your attention, hehe.

You can change the quilt as much as you want.

Today's gearboxes are equipped with synchronizers.

Even come: 1. Brakes.

2. Hit the direction.

3. Downshift. 4. Speed up.

It depends on whether you choose to consume fuel or not.

If you consume fuel, you can do 2 actions at the same time.

Otherwise the opposite is true. It is advisable to tap the brakes before cornering and then shift gears after cornering.

Turn on the turn signal before entering the corner, press the brake to drive the car, reduce the speed of the car to the right speed with the angle of the corner, remember not to let the car stop completely, and then immediately hit the direction, when you feel that the angle of the direction is enough, hold the steering wheel with your left hand, and follow"Step on the clutch - pick up neutral - bang the throttle - step on the clutch - hang the low gear - lift the clutch and fuel the throttle"When your series of actions is completed, your car will turn around, and then it's time to return to the right direction! ~

The main reason why manual transmission vehicles change gears constantly is because they change gears according to the road conditions and vehicle conditions. Each gear of the manual transmission corresponds to different speeds and speeds, and there are many car conditions and road conditions encountered during driving, so it is necessary to increase or decrease the speed, and it is natural to keep changing gears in operation.

At the same time, each car has an optimal shift speed range, and many skilled veteran drivers will frequently shift gears to match the optimal engine speed of the current vehicle. This results in a greater power output and better fuel economy.

First, the speed of the car has increasedAs we all know, the lower the gear, the greater the braking force of the engineThe greater the braking force, the greater the resistance of the car's movementThe additional amount of oil burned is used to overcome the braking force of the engine, and does not increase the driving distance.

This not only causes a loss of engine power, but also causes a waste of fuelSecond,

The main purpose is to ensure that the engine is always working at its bestAnd maintain the proper speed, so as to achieve the purpose of saving fuel and not damaging the vehicle. The most important thing is to slow down and slow down no matter what the situationStay safe and have a safe journey.

Why do drivers keep changing gears when driving? The road surface is not bumpy?

Keep changing gears while driving:

The different gears distribute the power generated by the engine to the four wheels in different proportions. Because the car is getting faster and faster from starting to driving, the demand for engine traction is different, and the different road conditions also need to use different forces, so it is necessary to have a gearbox to reasonably distribute the power required by the car to the wheels.

If it's simple to tell you, you can remember it. The first gear is 0-10km h (simply put, the car starts on the first parking space and you can change the second gear), 10-30km h second gear, 30-40 third gear, to 40 shift to the fourth gear, the general novice will not use the 5th gear, and you will know when you are proficient in listening to the engine sound, the sound is very loud if you do not upshift over the speed.

There is a difference in gear, your car has 4 gears, when you go uphill, if you open 4 gears, it will turn off, 4 gears are fast, and 1 gear is used for uphill and starting

Fuel-efficient There are also exchanges for playing.

Slow acceleration to follow the car: When you are slowly accelerating and ready to follow a car (that is, when you are not in a hurry), the speed has reached the speed you want, 3rd gear, the engine speed is 1800 rpm, can you upshift? Of course, after upgrading the 4th gear, the speed is about 1300, maintain the speed, save fuel, and save the car.

Overtaking: Downshifting and refueling! While downshifting, raise the engine speed to the previous 1800 rpm, or even directly down to 2nd gear, and increase the rev to 2500 or even 3000 rpm, at this time, you will feel a strong thrust, pull you and your car forward, continue to press the accelerator to accelerate, until you pass each other, and reach a safe exercise area.

And then what to do? Obviously, it's time to gear up and get back to a safe speed you want. However, the engine characteristics of different cars may be different, so some of the speed values mentioned earlier should be adjusted, in general, if it is a German car, you can reduce some speed appropriately; If it is a Japanese or French car, you should increase the speed appropriately.

The simplest way to determine the timing of gear change is: when the gear is added, the engine power is enough when driving, that is, it is easy to listen to the engine sound and you can change gears. When downshifting, it is the opposite, that is, the engine is no longer enough while driving, that is, the engine sound is dull, that is, it needs to change gears in time.

In fact, when going up a steep hill, do not shift gears when the engine belt is not moving, there should be a certain amount of advance, which can ensure the smoothness of the car in driving.

I'm a driving school instructor and I come to your question:

1. If the strength of the car is not weakened when the normal slope is rushed, do not need to shift gears, if you find that there is a weakening, (the refueling truck can not go fast) do not care about the speed, immediately reduce the gear, regardless of whether it is fast to the top of the slope.

2. Don't care about the speed, as long as the strength of the car is weakened, you must reduce the gear, the car begins to tremble when you go uphill, and you also need to skip the gear reduction (such as 4 minus 2).

Seeing that you are a novice, remember one thing, don't use the speed to change gears, feel the power of the car more (in fact, it is the speed), but also don't blindly look at the tachometer while driving, to give you a rough reference! Normal shift speed 1500-2000 rpm Rapid acceleration shift or hill speed 2500-3000 Downshift below 2000 rpm downshift However, some high-speed engines also need to add 500 rpm on top of this, such as the Fukang car!

1. Before going on the road, you must be familiar with where each gear is, because when you drive the car on the road, your eyes must always pay attention to the road surface and pedestrian vehicles, so as to deal with various unknown emergencies at any time, and it is impossible to stare at the gear to change gears, which is easy to have accidents.

2. When changing gears, you must remember to press the clutch to the end, otherwise you will not be able to hang into the gear at all. Although you have to step on your feet a little harder, you can push and pull the gear lever with your hands more easily and not too hard.

3. Shifting gears is not difficult, the first gear is to pull the gear lever to the left parallel to the bottom and push it up, the second gear is directly pulled down from the first gear, the third gear and the fourth gear as long as the hand releases the gear lever, so that it is in the neutral position and then pushes and pulls directly up and down, the fifth gear is to push the gear lever to the right to the bottom and push it up, and the reverse gear is directly behind the fifth gear, some cars need to press the round lump on the gear lever down to pull, and some don't use it, this depends on the specific model.

4. The gear must be adjusted step by step, and slowly increase in the order of the second, third and fourth gears according to the speed display on the tachometer. Downshifting is not so particular, as long as you see the speed of the car drop to a certain gear range, you can directly hang in that gear, such as directly from fifth gear to second gear, which is no problem.

5. As long as the car starts from the stop state, it must start from the first gear. The most negligent thing for novices is that when waiting for the red light, they often forget to take the gear lever out of neutral and then hit the first gear, but start in a few gears before stepping on the brakes, which will cause greater damage to the clutch and gearbox, and it will cost fuel.

If you hit the brakes, don't rush to downshift, because sometimes the speed of the car does not drop significantly with just a light tap of the brake, and you can continue to stay in the previous gear by pressing the accelerator again. However, if the brakes are applied heavily, and the speed of the car is significantly reduced, then the gear lever should be shifted to the corresponding gear according to the value displayed on the speedometer.

It's normal No need to change, what our driving school master said Uphill just step on the accelerator Don't change gears Downhill with some brakes, you can enter gear.

Of course, you have to change gears, climb in low gear, and you can't run up in high gear! The throttle is very soft!

I've only been getting my driver's license for more than 1 year, so I don't know, but to put it simply, it's to shift gears with speed. At 0 speed, it is 1st gear, change second gear if it moves a little, you can change third gear when you reach about 25 horses, 35 horses change to 4th gear, and if you exceed 45 horses, you can change 5th gear, and then you don't have to change it. However, if you slow down after applying the brakes, you should also change gears accordingly.

If the throttle is given early, fuel consumption will increase, and the wear and tear on the engine and clutch will also increase, but there is generally no major problem.

When the oil is out of the fit, the throttle can be given gently, and there is no need for a big foot throttle.

In addition, pay attention to the operating speed of the gear shift process, if you master it, you don't need to cooperate with the throttle at all, you can just clutch it too much.

For novices, it is not easy to explain if you don't know the principle.

When driving, it is necessary to accumulate the relationship between the speed and the gear time.

I think the most important principle you need to know about driving. Please take a closer look.

1. In the case of the same gear, there is a proportional relationship between the speed of the vehicle and the number of engine revolutions. There are formulas that can be calculated. In other words, in the same gear, the speed of the vehicle increases as the number of revolutions increases.

2, When to upshift? At the current speed, the higher the gear, the lower the corresponding speed. In other words, after upshifting (the default is that the speed of the vehicle is maintained at a constant speed during the upshift), the rev corresponding to one gear higher will decrease.

For example, 1st gear 2000 to 2nd gear, after the clutch is fully integrated, the number of revolutions is 1400 rpm. Upshifts generally don't need to jump. Note that if you upshift when the number of revolutions is low, then after upshifting, the number of revolutions will drop below idling, and it will turn off if you don't do well.

3, When to downshift? On the premise that the speed of the vehicle drops, if you want to accelerate with oil again, the number of revolutions is very low and the torque is insufficient, so you need to lower to the appropriate gear and then give oil. This requires a relationship between speed and gear before you can become proficient.

For example, now in 5th gear, there is a situation ahead, you need to slow down, directly step on the brake to slow down (generally speaking, the clutch does not need to be stepped on at the same time, and when the number of revolutions drops to close to idling, in order to avoid stalling, you need to step on the clutch to hang neutral). ), find that the situation ahead is lifted, there is no need to continue to slow down, you need to accelerate, directly downshift to the corresponding gear, such as 3rd gear, just refuel. During this period, you don't need to lower 4 gears first, then 3 gears, just go directly from 5 gears to 3 gears.

If you are proficient, click the throttle during the downshift process and make up for the number of revolutions, which will make the shift more comfortable.

Based on the principles described above, please make your own assumptions about what to do in each situation. The oil release fit is a must to be practiced.

If you don't understand, please ask.

For many novices, driving a manual transmission to go out often encounters various problems, which is not as easy as an automatic transmission. So how to correctly grasp the timing of gear shift when a novice drives a car, and what problems need to be paid attention to?

The oil is given early, except for the waste of oil, there is no other effect, novices will be a little bit of bad control, it doesn't matter, slowly and naturally become proficient. There are also novices who drive better to drive the old car first, and novices drive new cars, which hurt the car.

The meaning of existence.

While we are ostensibly pushing the gear lever to shift, it is actually the transmission that works.

How does a car start and a bike? In the same way, static friction is greater than dynamic friction, and when the bike starts, it takes a lot of force, but when the bike starts, it only takes a small amount of force to drive forward.

The power of the bicycle is our own, and the power of the car comes from the engine.

It's just that engine students don't know how to intelligently distribute power, whether it is starting or advancing, they use the same strength.

So the transmission stepped forward and distributed the power.

It has saved a lot of lovely RMB for car owners, and its performance is remarkable.

How it works.

Transmissions are generally divided into two types: manual transmission, which uses a clutch, and automatic transmission, which uses a torque converter.

It may sound overwhelming, but you just need to remember that the principle of a gearbox is a set of gears.

Their relationship is like this, those who have strength have no speed, and those who have speed have no strength. Choose according to your power needs.

The automatic transmission is also to be shifted. Since the engine of a car is certain, it has a certain power p and a certain maximum speed. According to the formula p=f*v

With the increase of speed, the engine speed will increase in proportional function, when the engine speed reaches the limit, it is necessary to change to a higher gear (otherwise it will burst the cylinder) to make (engine speed v) smaller, and at the same time the F transmitted to the tire will become smaller, and the acceleration will be smaller. And so on. That is, to achieve a more stable engine speed, so that the car can obtain a wide range of torque and speed.

To put it simply, shifting gears is actually about adjusting different gear ratios to get different speeds and torques.
