On a dry road, the wheels hold securely to the road surface, and centrifugal force can't take down the car.

But it can turn it around!

And here's what else the driver needs to know. The lowest center of gravity is empty car. At full load (with cargo in the trunk and passengers in the cabin), the location of the center of gravity increases significantly.

And the centrifugal force is just applied to the center of gravity of the car, and this must be taken into account when cornering.

With cargo and passengers, the probability of tipping over is higher!

And now we recall the course of school physics:

Centrifugal force is directly proportional to the mass of the vehicle, directly proportional to the square of the speed, and inversely proportional to the turning radius.

If the speed is increasedtwice, the centrifugal force will increasefour times.

Conversely, if the speed is reducedthree times, the centrifugal force will decreasenine times!

With the turning radius, too, everything is clear - than more radius rotation (that is, the smaller the curvature of rotation), the less centrifugal force.

Interestingly! Even without knowing about the existence of this formula, in life we act strictly in accordance with it - we reduce speed before entering the turn, and when passing the turn, we try to “straighten the curve” to the maximum, that is, if possible, we try to increase the turning radius. Such actions are prompted by the vestibular apparatus, which is instilled in us by the Creator.

What happens if you press the brake pedal while cornering?

With any braking, the weight of the car is transferred to the front wheels. That is, the front wheels are firmly pressed against the road, and rear wheels on the contrary, they tend to get off the road.

In such a situation, a small lateral force is enough for the rear axle of the car to begin to rotate around the front axle.

This phenomenon is called car skid.

Where will this lateral force come from? To the greatest regret, it will certainly be taken, and there are plenty of reasons for this. What is worth only one centrifugal force!

When passing any turn on the car, the centrifugal force applied to the center of gravity of the car necessarily acts.

Since the front wheels always hold the road better (they are loaded heavy engine), then, as a rule, the centrifugal force shifts the rear axle to the side. The car skids while cornering.

If now we brake out of fear, two more will be added to the centrifugal force - the braking force of the front wheels, and the immediately arising force of inertia.

Looking at the picture, it should be clear that now the car will be thrown to the side of the road and there it will definitely roll over.

Therefore, braking during a turn is highly undesirable. You need to slow down before entering the turn, and the turn itself should be passed, as they say, “at a stretch”.

That is, we press the gas pedal, but very slightly so that the car passes the turn without slowing down and without accelerating. In this case, no forces (except centrifugal) act on the car, and we reduced the centrifugal force itself to a safe limit, reducing the speed before entering the turn.

It is necessary to understand - in order to create conditions for skidding a car,

it is not at all necessary to drive along a curved section of the road.

A car skid can also occur in a straight section, and sometimes it’s enough just to slow down or, conversely, sharply press the gas pedal, or sharply turn the steering wheel when driving around an obstacle.

And what to do if the skid begins?

The answer is very simple - you must immediately get rid of the cause that caused the skid!

1. Car skidding can occur during heavy braking.

When braking, the car is dragged forward by one single force - the force of inertia. And this force is applied to the center of gravity of the car.

And as many as four forces resist the force of inertia, namely, the braking forces four wheels car. In this case, the main load falls on the brake mechanisms of the front wheels (it is not in vain that the front brake pads wear out faster than the rear).

So, when braking, the rear wheels are weakly pressed to the road and therefore prone to blocking. It is enough to sharply press the brake pedal, and now they no longer roll, but slide, losing traction with pavement. In this case, almost all braking is carried out only by the front wheels.

Now imagine that the left front wheel brakes more effectively than the right. There can be many reasons for this - for example, different tire pressures, or the asphalt is dry on the left and wet on the right. Yes, sometimes it is enough for one of the wheels to roll along road markings, and another on asphalt!

In this case, when braking, a moment of forces immediately arises, tending to turn the car around.

As a result, the left side of the car starts to move more slowly than the right side. There is a skid of the rear axle of the car or just a skid of the car.

If you don't stop braking now, further movement will resemble the movement of a stone thrown on ice - the stone spins and spins, but flies in a straight line to where it is dragged by the force of inertia.

First natural reaction inexperienced driver- Apply even more pressure on the brake. As you understand, this means that the skid will continue.

Reverse action can change situations - take your foot off the brake pedal.

They took their foot off the brake pedal, and immediately the moment of forces that turned the car around disappeared (the wheels roll freely). But the force of inertia has not gone away, it still drags the car forward!

It doesn't matter, we turn the steering wheel in the direction of skidding and align the trajectory of the car.

(Compare this picture with the one above. You can see how the driver turned the front wheels in the direction of the skid in this picture).

Note. As we have already decided, a skid of a car is a skid of the rear axle. The rear wheels tend to move closer to the front. In this case, while leveling the car, the driver turns the steering wheel towards the approaching rear wheels.

This is what is called "turning the steering wheel towards the skid».

2. Vehicle skidding may occur during hard acceleration.

During acceleration, the alignment of forces is exactly the opposite.

Now the force of inertia is directed back, and the drive wheels pull the car forward. And if the drive wheels reliably hold the road (they do not slip), then the car behaves perfectly, obediently fulfilling all the wishes of the driver.

However, there is no guarantee that the left and right wheels always hold the road in exactly the same way. We have already mentioned the possible difference in tire pressure, or, say, the roadway on the left is dry, and the right is wet.

Therefore, skidding can be obtained not only during braking, but also during acceleration.

It is enough to sharply press the gas pedal (especially on slippery surfaces) and the drive wheels will begin to rotate with slipping. And any slippage of the wheels is a loss of traction.

If the drive wheels are rear, the rear axle will skid.

If the drive wheels are front, the front will be blown to the side.

So in all cases, the recipe is the same - it is necessary to get rid of the cause that caused the skid,

that is, in this case– reduce pressure on the fuel supply control pedal.

3. Vehicle skidding can occur when the steering wheel is turned sharply.

Sometimes drivers have to swerve sharply when avoiding obstacles.

Imagine that the driver, moving at a speed of 60 km / h, at the last moment decided to go around the sewer manhole.

But a sharp turn of the guide wheels is also a kind of braking. In the forward direction, the speed of the car drops sharply, and the car noticeably crouches on the front wheels.

And once there is braking, the force of inertia immediately appears, while the car body is already deployed - ideal conditions for skidding!

In the summer, nothing terrible will happen on dry pavement, just the car will rock back and forth when driving around an obstacle.

But in winter, skidding is guaranteed on a slippery road. Moreover, in the next moment all four wheels will slide.

And in the summer, if the speed is under a hundred, events will develop in exactly the same way.

What to do?

Yes, everything is the same. As soon as the driver feels that the car is going into a skid, it is necessary to immediately get rid of the cause that caused the skid. And now God bless him, with this hatch.

Quickly (but smoothly!) Turn the steering wheel in the direction of skidding.

The front wheels "cling" the road (stop slipping), the car's controllability is restored, and the car obediently returns to its lane.

It's time to talk about the difference in management front wheel drive car and rear wheel drive.

Both the one and the other go into a skid in exactly the same way. But here they get out of the skid in different ways. This is due to the fact that the rear wheels pushing car, and the front pull automobile.

Imagine a person who has tied a stick to the back of a sled and is trying to push the sled with it.

After all, they immediately begin to fold to the left or right. That is, by analogy with a car, the rear axle will carry a pushing force.

If a person guesses to tie a stick or just a rope in front and pulls the sled, then they will follow him like a thread after a needle without any drifts.

This is what distinguishes front-wheel drive from rear-wheel drive. If the rear wheels pushing mass located in front of them, then the front wheels pull the mass behind them.

That is why, leaving the skid on rear wheel drive, We gradually reduce the pressure on the gas pedal, trying to pacify the centrifugal force and restore controllability of the car.

And that is why on front wheel drive, We slightly increase the pressure on the gas pedal so that the front wheels pull us out of the skid.

How to get out of a skid on a rear wheel drive.

So, at the turn, a skid of the rear axle of the car arose (the rear wheels slide along the road, and the centrifugal force carries them to the side of the road). And it is the rear wheels that we drive.

If now we add torque to the drive wheels (that is, press the gas pedal), the situation will only worsen - not only are the rear wheels slipping, but now they are also slipping, and traction is completely lost.

At the same time, you can’t press the brake pedal or sharply throw the gas - in this case, the inertia force will be added to the centrifugal force, and this will only increase the skid.

We remember our common universal principle- you need to get rid of the cause that caused the skid.

And the centrifugal force brings us. Well, it's impossible to get rid of it completely, but you can reduce it if you slow down.

Just slow down slowly slightly reducing the fuel supply while turning the steering wheel in the direction of the skid.

After the car's controllability is restored, we complete the turn.

How to get out of a skid on the front wheel drive.

And again on the turn there was a skid of the rear axle of the car. Only this time the car front wheel drive.

What do you think, if you now turn the steering wheel in the direction of skidding and add torque to the drive wheels, will the front wheels pull us out of the skid?

But, perhaps, they will pull it out!

Just remember!

You need to increase the pressure on the gas pedal slightly, very smoothly and very carefully, avoiding slipping of the front wheels. How will they pull if they start to slip?

Modern cars are equipped with all sorts of devices that help the driver avoid trouble on the road.

Among these smart devices primarily refers to ABS – anti-lock braking system.

However, you should know that the anti-lock braking system is very good only in straight sections. When braking, it so skillfully redistributes the braking force across the wheels of the car that all four wheels always hold the road securely. And this, in turn, eliminates the skidding of the car.

But against the lateral force, that is, against the centrifugal force that occurs on the turn, the ABS is powerless.

On a dry surface, centrifugal force can simply overturn the car.

On a slippery surface, the same centrifugal force can easily skid the rear axle of the car ...

… or even take the car off the road completely. And then no ABS will not help.
