The trial… This term is familiar to many today. Competition for Moto and bike trial attract thousands of enthusiasts for these new sports. But if the trial fits of the serial technique, for trials on the bike to buy two-wheeled machine in the store is impossible. Athletes tend to create cross bikes themselves, based on one of the models produced by the industry.
They parted ways at the dawn of the automobile, and since then, the development lines are not intersecting until now… we are Talking about a motorcycle and car.
All wheelchairs domestic production have a primitive manual transmission.
To use a bike instead of round sprocket Ellipso suggested in 1892 Professor V. Prusakov. He decided to put the rods along the minor axis of the ellipse that has allowed more efficient use of the power of the cyclist. Experiments have shown that even an inexperienced rider on a machine with the elliptical sprocket expends energy approximately 30% lower than on moving with the same speed filemashine with a round sprocket. And according to the American engineers, the use of oval zubchatki increases the average speed of a cyclist by about 14%.
Transform an old truck motorcycle IZH-type I was going for a long time. At first I wanted to make something like a scooter “Ant” (like the truck, by the way, once told a “M-K”). However, the design was unreasonably heavy and bulky. And besides, it needed a massive differential or, in extreme cases, overrunning clutch, and to build all this in the country, in a home workshop, it was pure utopia.
In the previous issue of the journal “modelist-Konstruktor” readers acquainted with the design of the aircraft “Cree-Cree” of Michel Colomban, who received a truly worldwide fame. According to many aviation experts, aircraft types “KRI-KRI” close to the limit of miniaturization, while some Amateur designers are trying to create models of even smaller size. However, when reducing the size of the aircraft becomes more dynamic, increasing its angular speed, the movement becomes korotkoperiodnye, causing reduced reaction time of the pilot action on the rudder. And at some point it may be insufficient for normal driving.
Not once I tried to build a simple convenient and compact micromatic. However, after building and testing several cars with the engine D6 revealed the shortcomings of the stereotyped repetitive on all of them: awkward pose (especially for tall riders), no auxiliary pedal drive, the need to start, as they say, “push”, small trunk… of Course, all this is offset by the small size and low weight machines.
“I intend to build a car for wide use. It will be large enough so that it will fit the whole family, but small enough that one person could operate it. It is made of best material and designed in the simplest methods possible in modern technology. Despite this, its price will be so low that every person receiving decent content will be able to buy a car to enjoy with your family, relax in the open fresh air.”
What does a mini-tractor “Ant”? What lies behind the pleasing to the eye successful?
Mount klementieva in Koktebel — a place special and wonderful in their own way. Fans of soaring rightly consider it the cradle of Soviet gliding, nascent in our country in the distant twenties, and hang gliding, the appearance of which happened before our eyes in the seventies. Today, at the turn of the new decade, the slopes of the legendary mountain was chosen by fans of the new aerial sports — paragliding: so, relay the makers of ultralight aircraft continues.
