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.
SIDE — DUMP TRUCK. To deliver the current grain from working in the field combine to drive if the feed to the farm building materials to the rising walls of the new building is everywhere in the village the required on-Board the vehicle. Such popularity is due to universality of his body fit for any cargo. One bad — unloading process, requiring considerable manual labor. Whether it is a truck! In a matter of seconds this “scoop on wheels” takes an inclined position, and the cargo already on the ground. Not accidentally, rural innovators are constantly find the most simple solution: how to get side car “samoraspustitsya”.
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.
This model can successfully build students 4-5 classes. Best to start with the housings. It can be done chiselling from a block of wood or stacked. If the housing is stacked, panel it with plywood with a thickness of 1 mm or thick cardboard that cover nitrovarnish to not soaked in water. The body parts glue nitrocream.
Simple radio-controlled model aircraft. Do note that this article is designed for those who prefer to build RC models are not alone, and together with two or three associates. For such a complex and expensive Hobbies well together and the work is fun and the purchase of remote control equipment and engine “rainbow 7” is significantly cheaper. By the way, for beginners you can recommend not too expensive equipment, FOCUS 4, FOCUS 6 Korean company Hitek — the first cost is about $185, the second $220.
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.
This car was designed (if one can call the process of thinking about design and estimates of size) and made for several hours after my brother and I received a message from his father from the village with a request to help him make his entrance to the house. It was clear that a stretcher we cannot do the work expected is significant, and any mechanized commercial vehicles was not expected.
Many people, especially those who live in rural areas, had to build, and those who had, perhaps still have, because man by nature loves to build is not only a necessity but a pleasure from the creative process. Here if it would be possible to mechanize here is a time-consuming work…
