Do you have to go down in gear and gear when driving a car?

The car must downshift sequentially, firstly, so that the car can slow down by the braking force of the engine, secondly, to hit the throttle to maintain high revs to ensure the speed of exiting the corner, but once the downshift is done by jumping, the differential between the engine and the gearbox will cause the car to suddenly slow down, that is, it has braked before the line into the corner, if you add heel toe blast oil, the car is likely to not even be able to hook up, in many cases the gear jump is a way of emergency braking, especially when the brakes fail This is a way to use the braking force of the engine to stop the car in the way of jumping gears, the specific method is to hang into the fourth gear or higher gear when driving, step on the clutch and bang a foot of oil, and then hang into the first gear, at this time, the huge difference between the engine and the gearbox will make the car stop abruptly or even shut down, but under normal circumstances, the more than two gears, the general gear lever can not be hung in at all, I don't believe you will know if you try to drive.

Of course your idea is feasible, but it's not practical in racing, so why would I waste my brakes and not use the engine's braking power? And according to you, the clutch should be pressed until the speed of the car drops to a speed that can be tolerated in third gear, otherwise if you don't step on the clutch, it will cause the gear to stall and stall, unless it is put into neutral, but how to make up for the loss of rev in this time, so that the meaning of the heel toe is lost.

The car must be technically --- heel toe action.

Any race car must have four pedals, in addition to the usual throttle, brake and clutch pedals, and a fixed pedal (dead pedal) that provides the driver to step on the foot when not shifting. This pedal is used by the driver to keep his feet on to keep his body balanced when the car is turning.

Before the car reaches the end of the straight at high speed, ready to enter the corner:

1. The driver starts braking.

2. The rider steps on the clutch.

3. Downshift. 4. The driver uses the left part of the sole of his foot to step on the brake and move his heel horizontally, apply force, and step on the accelerator to increase the engine rpm. The heel toe action allows the driver to step on the clutch, brake and refuel at the same time, allowing the car to complete pre-cornering preparations such as deceleration and downshift in a very short time.

During downshifting, the clutch is detonated at the same time, which is mainly to increase the number of engine revolutions to the next gear, so as to match the additional number of revolutions required after moving to the lower gear. (For example, the speed of the car before deceleration is 180 km/h is equal to 7500 rpm in 5th gear, and when the speed is reduced to 120 km/h, the engine speed is equal to 5000 rpm in 5th gear, but the driver downshifts to 4th gear due to the different shifting ratios between 5th and 4th gear.)

Assuming that the gear ratio of 1st gear is, then the speed of the output shaft after shifting should be 3600 divided by about 1000 rpm! It is 1,000 rpm different from 2nd gear, which is nearly double! The meaning is that the speed difference causes the gear fork to not cut in, it is possible to not change into the gear, even if you go in, you will hear a huge tooth sound, and then the speed is forcibly reduced instantly, the engine speed is forcibly pulled up, destroying the original driving balance, if it is serious, the car will immediately lose control!

The straight doesn't have a heel toe, right? The heel toe is not yet for downshifting after entering a corner. From the very beginning of learning to drive, I knew what gear should be hung at any speed.

There are two types of heel toe movements, either with one foot clutch or with two feet. One-foot clutch: keep the clutch in the state of braking, clutch-fuel replenishment-downshift-release clutch.

The benefit is the fast shifting speed, but the lack of protection for the transmission synchronizer. Two-foot clutch: keep the brake state, clutch-neutral-release clutch-refueling-clutch-downshift-release clutch.

The advantage is to protect the synchronizer, the disadvantage is the slow speed. Generally, rallies use a two-foot clutch heel toe action, and a track race with one foot clutch.

One kick in the upper space, and another kick in the gear. When changing gears, it will be difficult to downshift due to the difference between the gears, especially in the spur gearbox. If you don't use the heel toe action, even if you can downshift smoothly, the wheels will pull up the engine speed, which will accelerate the clutch wear at least and damage the engine in severe cases.

The main thing is to protect the engine and gearbox, and ordinary modified cars do not need to do heel toe action at all.

There's a reason why the upstairs didn't hit the throttle until neutral, because although the clutch separates the variable gears from the engine, the gearbox gears still fit in with the transmission gears of the body.

The real meaning of the racing car's heel toe action is that it has a great protection effect on the gearbox and clutch, and it can also prevent the loss of control caused by the engine brake instantaneous transmission during downshifting, which can cause the drive wheel to lock up.

Using the heel toe action, the right foot is slightly refueled while braking, so that the engine speed can be pulled up after the clutch is stepped on the left foot, and after the smooth downshift, the engine speed corresponding to the current gear and vehicle speed at the same time as the clutch is engaged and the engine speed after oil replenishment can still be consistent, as far as possible will not let the wheel drag the engine speed, which means that the heel toe action is completed beautifully.

The main thing is to protect the engine and gearbox, but also to reduce the stutter when downshifting, which hurts the car very much, and the car is always under high load, which is dangerous. The toe itself doesn't do much to improve lap times.

The subject's understanding is correct.

The meaning of a foot clutch heel toe "oil replenishment, mainlyPull up the engine speed (but not the gear speed in the downshift).to prevent the frustration caused by the sudden increase in engine speed of the wheel after the clutch is engaged, and reduce the impact on the clutch, gearbox and engine; At this time, there is still a considerable speed difference between the two gears switched, and the reason why the downshift can be attributed to the synchronizer. Without a synchronizer, it is difficult to downshift smoothly with a clutch heel toe.

If you want to flatten the speed difference after downshifting, there are only two feet clutch downshift: the first foot is lifted to release neutral gear and replenish oil, and the second foot is stepped on to lift and downshift.

You're saying it the same way in both ways.

1.Brake - step on the clutch - neutral - step on the brake and release the clutch and hit the accelerator This way has a neutral stroke It means that this way has a neutral first and then a low gear, so you have to press the clutch twice.

2.Brake - step on the brake + clutch + hang low gear + boom throttle - put the brake and release the clutch to refuel, this way does not enter neutral gear, but when braking, the speed drops, and at the moment of stepping on the clutch, directly hang into the low gear.

In both cases, most people now take the second approach.

And the first way is to be on the track, when you enter a corner, there is a car in front of you, and you can use more neutral to ease some time.

Avoid stalling when maintaining an appropriate following distance from the vehicle in front.

If you want to learn racing skills, you should go to a racing school, after all, racing is still a sport based on practical operation. Theoretical learning alone will not achieve the goal. Especially when you meet such a "understood" person upstairs again, even the clutch of the two feet came up, and the movement of the heel toes was reversed, didn't you delay your work in vain.

It reflects the current strong strength of many experts and scholars.

Sisters, sisters for life.

It's actually quite simple that the heel toe refers to the action that the driver makes in order to maintain the engine's rpm when changing gears.

The specific method is: generally when changing gears in the car, it is mostly when the driver slows down, so at this time, the driver steps on the clutch with his left foot, and the right toe presses the brake while pressing the accelerator with his right heel, the purpose of this is to keep the engine at high speed after the vehicle shifts at high speed, so that the gear shift is smoother, and it can output more horsepower after entering the gear, and Schumacher will always step on the accelerator when cornering to maintain the high speed of the engine.

Don't practice if you don't need to, it's easy to cripple the car when you learn, and it's easy to be rear-ended.

As long as you want. What's not to do with safety.

toe and heel down shift!

If you don't practice this trick for a few months, I'm afraid no one will be able to use it well, it's not easy! The main purpose is to tell the engine to keep the engine high speed while stepping on the brakes to slow down when cornering, and to return to high speed immediately after cornering.

Of course, you can use it when you are driving, but it is rare to turn at such a high speed in city traffic, right?
