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.

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.

Before Summer!

Before Summer!

How is your car doing?

It's easy to get sick when the seasons change, so please take care of your health.
Yes, let's take care of our cars and motorcycles too.
With the weather getting warmer, is your radiator fan spinning a lot?

Even if the coolant is changed at the time of vehicle inspection, if the radiator core* is covered with debris or dead insects, the air cannot escape through the gaps in the radiator core and overheating may occur.

* This is the radiator core.

radiator core

If you feel that your fan is spinning a lot recently, there is no doubt.
The cooling effect is reduced. You had better wash the radiator core with a high pressure washer or a soft brush.

If you think, " I don't care yet," it may be too late.
The signs of overheating are hard to see during the rainy season because it is wet with rain, so overheating may occur in mid-summer after the rainy season.

Especially for motorcycles, the radiator is located right behind the front wheel, so sand particles bouncing up from the front wheel can also get caught in the radiator.

It's time to start taking precautions against the heat!
