What is needed by the relegation when switching gear. Why do you need a double press and fugazovka? Double clip clutch

Want to blame the bar? Turn on low!

With a decrease in gear, the situation is somewhat more complicated than with their increase. If you are a novice driver and for you it is not obvious, do the following: turn away up to 50 km / h on the III gear, turn on the II transmission and quickly, as usual, release the clutch pedal. As a result, the tachometer arrow sharply jums up, and the car hurts healthy. Try! Happened?

So it will always be with the transition from increased transmission to a reduced one, only the intensity of the jerk will be different depending on the speed and transmission. Why does a jerk arise? As we show a sharply "bouncing" tachometer arrow, while lowing the transmission increases the rotation of the motor. If when switching from II on III gear, the arrow falls from 3500 to 2500 rpm, then when switching from III to II, on the contrary, it jumps from 2500 to 3500. This means that including reduced transmission, we will force the motor to more high revolutions. Since the rotating parts of the engine heavy, inert, they resist the promotion, which is expressed in the jerk of the machine. It turns out, jerk - as if protest a motor :)

Peregazovka or clutch?

So I recommend it regularly, each time the transfer is reduced to use the Peregazovka and, it is desirable, with a double pressing of the clutch pedal. Using Peregovzkov, you switch the transfer faster, smooth and safer for roadAnd for the details of the car than with the smooth release of the clutch pedal. Of course, the Peregazovka is difficult to master, but if you do it all the same, then I'm afraid you will like it, yes, so that you will not tear off! And then you will not put you on the automatic :)))

Toe Forever!

By the way, Peregazovka (in English: TOE) came to us from the old good fifties, with trucks, on which there were no synchronizers and transmission without a penipipation could not be included in principle. Therefore, today there is sometimes a point of view that, they say, Peregazovka is an anachronism, hello from the past, and that any modern car is perfectly coping with a decrease in gear and without fueling. If you think so, you will return to the second paragraph of this article and once again we will turn on the reduced transmission without fugazovka. And for greater clarity, we turn 50 km / h not on the second, but immediately for the first gear. Only choose a place on the road quieter and sewn, and then fly away from the road, it will not seem little ...

I also add that Peregazovka is an integral component of the arsenal of techniques of any professional rider. So if you plan to do sports driving, Peregazovka for you is obligatory for development! Try, dare!

And if you need practice - come to the courses "Magic shift" or "Driving along a racing track". Beginner drivers will be more suitable for the course "Driving in the city", and advanced can also advise to pass the exclusive course of our school: "MBA course for the driver: the skill of driving a car."

Even if you are not going to comprehend the vertices of racing driving, in any case, Peregazovka is a driver's skill element Business card of the competent driver. Recommend!

With switching and lowering - all, and in the next article I will tell you finally

The generation learned in Soviet driving schools or chauffeurs worked on the old Russian auto industry would not have a similar question in a dead end. They know perfectly well what is a double look, what is the penzhazka and how to slow down the engine. These are the main questions that the driver should be mastering at the first levels of learning.

In the modern world, these issues are not relevant, since machines working on such principles becomes less and less. Until now, they function in rustic farmers, in our secondary schools as a visual example in labor, colleges, technical schools and of course in the army.

However, these questions need to know any driver, as it was the basis of the basics and in the case, God forbid, the ecumenical extension cataclysms, and if the earth turns into a deserted desert, Alya "Mad Max", then they will be relevant. Why? Because the only technique that will function is the old ones with lawns, two-weeks, army armored cars and other monsters of the Cold War.Ultra modern cars With tiptronic boxes, variasts and robotic transmissions are awesome in the summer as a sweet dream, which will not be destined to come true and comrades who are used to ride in the "D" position, or will be returned, or will run on foot.Let's go closer to the point.

What is a double release and passion?

Double Release and Peregazovka Mandatory Ballet Procedure With Pedals for Cars, Which box of transfers is deprived of synchronizers. It should be noted that before the boxes they were not installed, but later, when the engineering thought reached the moment that the car not only should be useful, but also convenient to manage, synchronizers appeared.

What are synchronizers?

Synchronizers are mechanisms that synchronize the rotational number of the shaft and gears. This makes it easier to switch gear, makes switching smooth and fast, and also reduces wear and damage. Yes, and eliminates the characteristic crossed, which everyone had to hear, especially when traveling on old buses.

Double seal is required not only when there are no synchronizers, but when they are faulty or the box is frankly dead.

The process of double squeezing is the switching to increased transmission by double pressing the clutch pedal. Why do you need it? I explain. It is necessary in order to increase the engine speed with shafts and gears, otherwise the second will scatter or jammed someone as lucky. How does this happen? You eat at the first speed, spoil the engine up to 3000 revolutions and plan to go to the second, you need to throw gas, click on the clutch and translate the lever to neutral, omit the clutch and wait until the engine turns to 2000 and press the grip again, which switches to second. Thus, you equalize the revolutions of the primary and secondary shaft. The box is fine and you can move on.

Peregazovka is the reverse process at which you try to reduce the transfer without making the checkpoint. It happens as follows. You are approaching the turn on which you will not be able to go through the fourth gear. You are slowing down and if you do not lower the transmission, then risk stalling, as you do not have enough revolutions to unwind the engine. You smoothly throw gas and squeeze the clutch, remove from speed and translate to neutral position. Next happens next, you need to gain revolutions, since the gear has a reduced transmission gear ratio above. You need to work a gas pedal or as they say to make a penzavo to raise the engine speed. The revolutions rose, they synchronized with the shaft and you can click on the clutch and switches to the reduced gear and continue to continue on it.

The main thing in the process of keeping the pause of the Peregazovka, with neutral transmission. It's like a novice who sits down for the first time behind the wheel of the car and does not understand how you can catch the right moment of clutch under the Trokhan, so that the car does not flush and do not stall. There are no special secrets here, the skill appears with experience.

Why is it necessary if modern machines with MCPP are equipped with synchronizers? This is a simple answer. Imagine that you have a pickup or a small truck, such as Gazelle and Valdai and you transport any cargo. The road is not always smooth and straight, there are descents and lifts or areas of rough terrain with a gravel road, and there are bumps, ravines through which it passes. Well, so that these very synchronizers have not ordered a long time to live after the first lifting, you need to use Peregazovka. You go to the rise and understand that the car will not extend on this transmission, there will not be enough revolutions, you make a penzavzka, moving to a reduced and the car under the slope is not difficult to switch, without losing the necessary inertia.

There is another moment that every driver should know - engine braking. Why he is uncertain if I have four brave wheels that will do everything. Needed, especially when the brakes refused, ice or steep descent in the mountainous area. In these cases, the ability to slow down the engine is simply necessary. How does this happen? Suspend that your brakes do not cope, switch to reduced gear, engine speed will increase, and the speed on the transmission will fall, since you switch to low. The car will start slowing down. Next, the same way is switched to the moment until the danger passes and you can either continue to move or use brake systemto stay. But this is on the manual transmission, and how to slow down with a machine gun? It is necessary to translate the box to Overdrive and gradually reduce the speed when the speed falls to 90 km / h to translate to the second and wait for the code. Speed \u200b\u200bwill drop to 50 km / h, then switch to L. Everything is simple. However, most modern automata do not require such televitations and adapt to your manner themselves if you have thrown gas at a certain point, then due to the shortage of revolutions, it will reduce the transfer, is inhibited by the whole design.

There are a lot of fugazovy types. Its initial use was due to the lack of synchronizers in the variable transmission, which excluded their smooth inclusion. To date, the relief is used for a smoother shift of the engine speed when the transmission is lowered at high speed. In cases of lowering the engine and the gearbox, there is a large load, which can adversely affect performance.

How to make a passage?

  1. With a standard perigendum on the rise, before overtaking, in turn, reset the fuel supply and squeeze the clutch. Without stopping in the position of neutral transmission, lower it.
  2. Cropper sharply and let go of the accelerator pedal and briefly increase the fuel supply. We bring the engine turnover to the maximum torque value. We release the clutch and open the throttle.
  3. When decreasing through the transmission, we turn off the fuel supply to the engine, squeeze the clutch. Turn on neutral transmission and bring the speed of rotation crankshaft The engine to the maximum torque value with a reserve to turn on the reduced transmission.
  4. We include reduced gear and let the clutch pedal. Increase fuel supply.
  5. In the event of an extreme situation, we use high-speed relief. Before the engine starts to lose turnover while holding throttle valve In the open position, slowly turn on the clutch.
  6. At the moment of sharp rise, turning the reduced gear and clutch. Holding off the shutdown, you drive a clutch slip, which will make it possible to raise the crankshaft rotation frequency to the level you need.
  7. By applying me to compensate for revolutions when increasing the transmission, turn off the clutch, we translate the gearbox to the neutral position. Sharply, but we increase the doses and lower the fuel supply. We include increased gear, we remove the leg with the clutch pedal and open the fuel supply.
