Load transfer! 3)

Load transfer! 3)

Hello, are you able to transfer the load with the image of drawing a circle?

This time, it is an advanced version.
Let's try to draw a bigger circle outside of the basic smooth circular load transfer.


Well, it's the commonly called "drifting".
There are many ways to say "drifting".
It depends on the performance of the car, the setting, the way of making the triggers, the drive system, etc... but that aside, the normal load transfer is an image of drawing a circle, however the drifting is a load transfer that adds a parabola to the basic circular movement. 

The size of this parabola depends on how it drifts.

"side brake"
"engine power"
"brakes"
"inertia"and "feint"

There are various triggers for drifting, but if the load transfer is not smooth, the car will spin.

"Centripetal force" and "centrifugal force" generated by moving the steering wheel to "inertia" of the driving force of the car, and "center of gravity".

With these in mind, we have to control the grip of the "front wheels" and "rear wheels" to make a parabolic drifting.

I used to practice drawing clover ♣when I was young.
Nowadays we live in a world where it is difficult to find a place to practice, but if you have a place and an opportunity, please try your best.

That's all for today.
See you in next blog!

Load transfer! 1)

Load transfer! 1)

Hello everyone ♪

Are you doing your best  "not to grip too tight" or "not to pry" the handle?

This time, let's talk about "load transfer".

It is easy to understand if you have a G-sensor (accelerometer), but the direction of movement of the car is a combination of three directions: front-back, left-right, and up-down.

The load moves backwards when accelerating, forwards when braking, to the left when turning right, to the right when turning left, and up and down if there is a gap.
This vertical load transfer must also be controlled to some extent, but in this article I will talk about the forward and backward load transfer.

This is about acceleration and deceleration, but also about acceleration by accelerator work, engine braking and foot braking.

First of all, the role of the engine brake is only to be used for a "smoothly shifting the load transfer".

When full braking from full acceleration, if there is no engine brake, the center of gravity will move rapidly from the back to the front, and the stability of the car will be impaired, and passengers will also feel uncomfortable. 
With some exceptions, the engine brake is used only for postural changes.
Yes, basically I don't use the downshift engine braking.

The reason why the accelerator is pushed when downshifting in a race etc. is because of "Speed = Gear X number of revolutions".
And to sharpen up the next acceleration.
At full acceleration and full braking, try to apply force only in the direction of tire rotation.

Do not tighten your grip on the handle when moving the load back and forth.
And don't pry it.

next time,
Load transfer! 2)
In the next article, I would like to talk about "Left and Right" and "Left and Right + Front and Back".

Don't grip too tight! ~ Four-wheeled vehicles version ~

Don't grip too tight! ~ Four-wheeled vehicles version ~

Hello everyone!

Are you driving safely? Or are you driving like a maniac?

Whichever you do, it doesn't matter.
Let's drive in a way that doesn't bother others!

In this article I will talk about the method that I was taught to use to control the steering wheel during cornering and how to apply pressure.

 This is not a technique or knowledge to turn a corner quickly, but a trick for stable cornering.

I was taught this when I was 22 or 23 years old....

A few years ago, there was a story about a test driver of a car manufacturer in Japan in NHK's program "Professional".  

This test driver was talking about 'holding the steering wheel with three fingers'*.
The reason he said was "to feel the behavior of the car"
*Usually it's thumb, index finger and middle finger.

What I was told at that time was, "Don't gouge the steering wheel."

"If you turn the steering wheel while braking, there are places where it gets heavy.
When you turn the wheel while accelerating, there are places where the steering wheel gets heavier."

The tyres exert their force in the direction of rotation, but applying it laterally with the steering wheel increases the burden on the tyres.
"If the road surface is good, the tyre will do its best, but it will lose quickly, it will sag quickly.
In bad conditions, you lose grip.
If you let the tyres do their simple job, they will last longer and not slip."

If you drive with this in mind, you should not squeeze.
If you tighten your grip, you won't be able to feel the kickback from the steering wheel.
You can feel the behaviour that the cars dislike.

If this behaviour and load transfer can be done smoothly, the passenger will not get motion sickness.

If you can do this, your safety margin will expand.
