Student scientific-technical conference of faculty road cars of the Moscow motor-road University this year attracted the attention not only of students and teachers, but also industry representatives. Still, many reports of young researchers it was about issues of importance to the national economy.
Doctor of technical Sciences Professor A. G. Ignatov enthusiasts of technical creativity known as the author of a number of original designs of micro cars, party contests and demonstration runs of homemade vehicles. The appearance created machines always arouses keen interest. Not to say that these designs are technically refined or Shine external perfection. Far from it: Professor A. G. Ignatov always strives to use the most available materials, but to get the maximum beneficial effect. Here is his own formulation: “I need mechanical undemanding pet. Unpretentious, like a mule. Avtomol. Perhaps better not say. Don’t need beauty need high performance, reliability and endurance. Don’t need comfort — I need the utility and simplicity of management. Don’t need high-quality and expensive finish you need a good resistance y resistance of coatings, requiring minimal maintenance and expenditure on maintenance and repairs.”
“Born, live and work in rural areas, writes to the editor our reader N. Kurbatov from the village of Borisovka-2 Belgorod region. Since his school years always was doing something: model ships, planes, although no tools (except a pen knife), no literature on this subject at that time was not.
Amateur designers often begin construction of the car, relying only on intuition, without any calculations. Most often in such cases the performance of the machine be not the such of any wanted the Creator, and the individual components break or wear out quickly.
Our magazine has repeatedly written about Krasnodar, Stavropol, Ural tractors, motologic, milling rippers, electrocore created in the circles of young technicians. These machines — good support and on the school grounds, and on experimental plots and in the field.
When vehicle type is defined: scheduled its approximate dimensions, weight, number of seats in the back, the engine, comes perhaps the most important stage of design development of the layout. Layout is the overall structure, and relative position of all parts of the structure. It would seem that a depot purely technical: linking dimensions, calculation of loads and so on. But no, it starts not with the mechanisms and numbers.
About the miracles did not suspect in a small garden cooperative near Bryansk. We gardeners in mind one thing: get the water from wells. In the heat of all able-bodied people are chained down to heavy handles cast iron pumps. Need to download bucket after bucket to water the thirsty seedlings.
Somehow caught us a description of the six-wheeled Rover “Giger”. The main nodes it was very simple. Absent transmission, driveshaft, rear axle — these, in General, quite complex and heavy assemblies. Small engines — separately for the left and right sides through a V-belt CVT transmit torque with its series of wheels connected by a chain. The supports of the axes of pneumococcal rigidly attached to the body and turns was carried out by adding the engine speed on one side and reduce the speed of the other.
The car, which will be discussed, began to make acquaintance of mine in the late 1980s, when the automotive abundance was not far off, but we did not yet know. However, as soon as he made the frame with pendants, the enthusiasm waned; I had to continue the construction of the car to me. Having estimated the possibilities, I decided to take this job, especially because experiences in such a case I had earlier today I have restored practically from scrap “Moskvich-401”.
In the last issue, we reported on the unusual at first glance, the method of drying wood in the bath water, between the electrodes, the supplied current of industrial frequency. This technology shortens the production cycle and ensures high quality products. However, the method is designed primarily for handling hard wood.
