The vehicle is made according to the scheme proven by the tractor “Kirovets”. He has the same “breaking” the frame and drive on both bridges. What gives? First, the permeability. Frame, continuously curving, as if tracking the terrain. All four wheels are constantly in contact with the surface. This eliminates the overload of individual wheels and slip them on uneven ground and secondly, the maneuverability. The hinged frame is sensitive to even the slight deflection of the steering wheel and allows you to turn almost on the spot. Thirdly, constructive simplicity. In this scheme, you can use exactly the same front and rear axles. Simple turns and the engine mount.
For many Amateur designers is one of the most challenging elements is the frame. On it are mounted the main aggregates, it determines the strength and dimensions of the future car. And to make the most simple and reliable — welded — not always possible. That’s why published in one of issues of “Panoramas “M-K” design of motor-plow assembled on the base frame from the bike, interested many of our readers. About your veloplugs created by podcast magazine, says our reader of the Kharkiv region, V. A. Zayets.
The editors have received many letters on the publication of “Biogas: and warms, and cooks” (see “M-K” № 1, 1987), based on the materials of the Romanian journal “Technium”. Of readers was attracted by the subject and documented in the design. Many are interested in the details of the devices bostanova, asking how to make the individual nodes. Further clarification and recommendations for possible solutions to the structural elements gives our consultant engineer P. Zach.
For his bike, I chose a folding bike “Desna-2” In model-849 with smaller wheels (20 X 1.75). To install it on the motor, did some fine-tuning.
The laboratory experimental machines Orlowski city Palace of pioneers named after Yuri Gagarin a lot of interesting and original works. At the regional exhibitions NTTM they attract the attention of visitors of all ages. And no wonder! The search range of the young designers wide: training glider and walking robot, a flying car and microtracker. With every new car the guys are in the way of true researchers: outlining the purpose, carefully studying the existing experience, then, given their own capabilities, define the technical requirements to future design and finally design and build it. So was born a twin recumbent LEM-05 (laboratory of experimental machines, 5-I model), the creation of the device, which says the head of the laboratory of engineer V. I. Borodec.
How much fun gives the children the winter snow. Technical Arsenal of this kind of leisure is increasing every year: the sled wide variety of designs, snow-cats, snowmobiles and many others. With the arrival of spring comes the turn of wheeled transport: bicycles, scooters, skateboards. Those who are fond of snow, making myself a summer toboggan — a simple wooden cart on wheels-bearings. With a roar they rush downhill on asphalt tracks. And well, if this alignment is away from the city streets, bustling sidewalk, where the “rider” on his own, devoid of brakes the projectile is not exposed to danger. But better not to hope in case, and try to make it fun safe and useful: to make a simple single truck with steering and brakes, comfortable and safe route and organize sports competitions.
In Latin language the word “cultivation” means “handling”, “cultivation”. If to explain in more detail, is the process of loosening the previously treated soil with simultaneous cutting of the root system of weeds. But cultivation is not only important for weed control. Tillage improves air and water regimes of the soil, which in turn enhances the activity of soil Microorganisms, creates the conditions for a friendly germination of seeds of cultural plants.
“Look through with great interest your section on “Small machines”: many useful find here Amateur gardeners. I decided to share a simple tool that has served me faithfully for years is terebilo for corn cobs”.
Unremarkable externally, water tower farm “Precepts of Ilyich” Spassky district, Gorky region. One year supplies the sleep of the villagers spring water. However, coming closer, you will not hear the usual noise water pump operation — he’s not here! And although the source is considerably below the level of the top of the container, water, with only a short respite, rise up! It is not a miracle? No, just Gorky handyman, locksmith-Borsi Yiwu L. Ceranova managed to invent and test the original hydraulic installation, in which for lifting water is used… the energy of the source. We offer our readers acquainted with the principle of operation and device.
