A diary of Jonasun

2000/8

The first curtain

I am seagull,,,
My name is JonaSun,,,

When it does such an expression, it seems to be famous novel.

I will decide to begin to write it carelessly.

It was a cause that there was my foot as Solarcar very firmly.

In 1995,

The end of summer,

At a place of meeting in a beer garden of Minami Aoyama,

"Toshiki san!, we want to participate in an Australian race."

"Continent vertical section seems to be possible with us of an amateur, and, with that purpose, please design a strong frame,,,"

Such a conversation was exchanged between Toshiki Takahashi who was an engineer of Honda and Yamamoto.

Takahashi designed a frame of 90 dream.

The bathtub type monocock frame which he designed still gives big influence to a frame design of high rank Solarcar team.

Yamamoto produced an impudent order to such a professional designer.


A condition of design:

*The machine which We can produce by a few budgets.

*Because there is not an expert of a mechanic in our team, maintenance is as much as possible free.

Parts use marketing product as much as possible.

The maximum speed on a design is 100km/h.

Takahashi easily undertook such a condition.

Several months later,,

He sends the plan which employed a lot of unique ideas.

The material of a frame is an aluminum square pipe of marketing.

However, what he selected is shameless of 120mm *60mm.

It was off common sense of solarcar, said to that light weight was good.

But,It is most suitable to support a thin body.

It is charm point that materials costs are cheap.


Front fork of a motorcycle is arranged on both ends of the frame done the layout of by an A character type.

It was simple and gathered up firmly.

And rear suspension was more individual.

It is a standard strategy occasion that a mount of a motor on an usual swing arm.

However, front desk fork of a motorcycle supports an end of the arm.

It is a swing arm of four points of support.

Because an axle is located in the middle of these support point, awful become firm rear wheel suspension.

These characteristics gave confidence to us.

"Mr. Yamamoto ,"

"You can run in three times of Australia with this frame."

Mr. Yasui of Simon which undertook production of a frame said.

As Mr. Yasui guaranteed it,


I ran the whole distance by two times of Australian Continent vertical section races already.

Of course it is a no trouble.

It is the second place private class in a race of 1999.



"I want to run on the Silk Road next."

Yamamoto has begun to say such a thing.

"Mr.Yamamoto,"

"It is good idea"

"I'll go together, too."

When Hans and Yamamoto meet, it is it in such an absurd story immediately.

But, a plan of the Silk Road passed for three years, it did not come true.

The sheen running with solarcar which can call a trade route of the ancient times a technical symbol for the 21st century is attractive.

It is a country different in both culture and a value system.

"Mr.Yamamoto"

"The Silk Road is the best selection, but if it is impossible we will cross Russia,,"

Hans did such a suggestion.

It is a bad habit of Yamamoto that is interested in anything.

At once they visited a captain of a Russian cargo boat anchoring in Akita Harbor.

They investigated possibility of transportation to Russia.

There is a road so long as I watch the Russian road map which was purchased since Yamamoto serves.

However, there is a part without a road in a hit to enter an inland department from the Far East.

In this place, the transportation by a train is not avoided.
