One of the main sources of environmental pollution is the vehicles. Therefore, constructors have a natural desire to create alternative, environmentally friendly means of transportation, which fully applies and recumbent. As the basis of its development, we adopted the design of the velomobile V. Mazurchak (“modelist-Konstruktor” No. 10 of 1987). But the technical capabilities are not allowed to repeat the machine one to one, we are particular to this and not sought. Besides, from the point of view of “strength scientists”, analog velomobile is, in our opinion, not very successful scheme of loading the important elements: the junction of the front and rear parts of the frame and the axis of the rear wheels, which can cause breakage of parts or assemblies during operation. But I wanted to make the car reliable (and therefore is durable) and thus to meet at least 20 kg of weight. The velomobile was to have such dimensions that enable it to pass under a standard door of the apartment and fit in a regular (not cargo) lift. Well, that was easy to transport and store, wanted to make it more collapsible.
WALKING RECUMBENT
The desire to ski “with the wind” makes us resourceful athletes to invent a new sport: racing on skis towed behind a motorcycle (skijoring), boat and even horse. Today, it seems we are on the verge of “opening” another form of skiing-a tow sport where the athlete has to match the skills of the skier with the ability to manage a sailboat on the tires with very low pressure. Such towing is already popular among fans of winter tourism, as they allow us to travel long distances without special effort on the part of the athlete.
our Readers probably know of noma abbreviation TX-200. It is the tan called autocritic original design created by the famous in the circles of avtomodelistov Kharkiv V. Taranukha, in collaboration with the candidate of technical Sciences Y. Hajnowski. Creative Union of theory and practice turned out to be quite fruitful. Today we introduce readers to one of the most interesting developments of this magnificent design of the Duo — car railroad layout, created with the extensive use of available and relatively inexpensive units.
It all started with the fact that we are a young childless family bought two “Kama” and became interested in Cycling. With the birth of his daughter had to solve the task: how to travel together? Did a little chair, and set it on the rear trunk. It has served us faithfully for several years But the daughter grew up, and sit in the car seat she was cramped, uncomfortable, the idea of creation of easy folding, durable enough trailer stroller, quickly attachable to the bike.
Associate Professor of the Department “Technology of mechanical engineering” of the Mari state technical University M. L. Popov, having a great experience with Bicycle sport, sent a letter to the editor which described and theoretically substantiated his view on the problem of improving the reliability of the bearing unit of the carriage. Today we publish only constructive and technological proposal of the author. More than 20 years of experience continuous all-weather and all-season operation of my bike model-542 “Sport” issued in 1974, the total mileage of which amounted to about 100 thousand km, as well as analysis diary entries have led to the conclusion that the bottom bracket for reliability is in fourth place after floreina, driven sprocket and drive chain.
“Passenger car” combined with cargo trailer is an extremely convenient vehicle. However, it is not without flaws, which sometimes nullify all its advantages. In particular, significantly reduces the maneuverability of the car and it becomes almost impossible to reverse because the motorists unlike professional drivers a bad maneuver composite vehicles. Low passing “the Zhiguli” or “Zaporozhets” with a massive “tail” at the country and field roads. So, you need a simple and inexpensive malogruzovaja type scooter “Ant”, but with a closed cabin and higher payload. And best of all — based on motorcycle components and assemblies: this will allow you to register it as a cargo motor transport funds. Moreover, motor units are much cheaper car.
Limitless Russian expanses, but in winter their snowy immensity had become impassable for virtually all vehicles. That is why with the advent of powerful internal combustion engines, the designers started thinking about creating machines that are able to easily overcome this “snow-covered vastness”. The choice of propulsion device for a snowmobile vehicle, it was a small caterpillar, wheel Yes auger. In combination with the supporting pillars, mostly with skis – at the beginning of XX century was built a lot of all kinds of snowmobiles. However, such machines did not have either the terrain or speed.
