IN HARNESS – INTROTSIKL

IN HARNESS - INTROTSIKLIn October 1996 in the Udmurt Republic celebrated the 65th anniversary of the system of children’s technical creativity. In 1931 in Izhevsk was opened the first children’s technical station, later received the status of Republican. Over the years many students RSUT became heroes of the Soviet Union, doctor of technical Sciences, honored workers of science and culture, managers of industrial enterprises, masters of sports. Best work 236 young technicians Udmurt Republic were awarded medals VDNH USSR, many leaders awarded gold and silver medals, received the title of laureates of the NTTM, 42 pupil participated in the international exhibitions in Japan, France, Germany, Belgium and other countries.

Today there are 82 of a circle: primary technical modeling, air, rocket, ship, automodelisme, radio, design, karting, hang-gliding, where more than a thousand children and adolescents. On the basis of RCUT regularly hosts national competitions in technical sports.
 
He currently leads a team of Republican station of her former pupil, high achiever of public education of Russia Viktor Vasilievich Pryakhin. Under his leadership, RCUT is doing a great job in preparing and training teachers of labor training and teachers of additional education. It is interesting to note that most of them are former young technology.
 
Since 1958, with the assistance of RSWT in the Republic began to open clubs for young technicians at industrial plants, well-equipped and able to attract to work with children the most creative forces from among the engineers and workers. And today, in our difficult time, great concern about the younger generation show in clubs of young technicians, created on the basis of the famous Izhmash: “Motorist”, “Electron”, “planet”, “dawn” — is now passed under the auspices of RUT.
Among the best groups you can call the Children’s Home culture and syut, the city of Glazov, respectively headed by honored worker of culture N. And. Pashkova V. M. a New. These institutions have good facilities, well equipped laboratories and workshops. Very popular is the Museum of Children’s Home culture, which preserves and exhibits the most interesting works during the existence of the House.
 
For over half a century are excellent teaching teams in Mozhginskiy, Sarapul, Kezskiy stations. Thanks to the attention of the local authorities of the new government and the efforts of the Directors, S. G., Khrustaleva (syut city of Votkinsk) and A. C. Rodionova (syut village Game), these institutions received new premises and equipment.
 
Caring attitude to children’s technical creativity in the Udmurt Republic is a good example for the leaders of many regions of Russia. So here solves many of the problems, and main of them — the problem of employment of children and adolescents, and as a consequence the reduction of juvenile crime.

The Republic became the center of Amateur technical creativity of youth. In confirmation of the latest edition of planning a number of publications on materials of the Udmurt masters. The article “harness — introtsikl” — the first of them.
 
Introtsikl — unusual vehicle and very appealing to Teens. Our machine is designed and manufactured by students of the 5th and 6th classes in the circle “Design of compact machines of the” club of young technicians “planet”. The original version of a classic blisks was too unstable and unsafe to operate, it is possible was unless in a circus act. So I had to stay on the tricycle scheme with “broken” frame. Of course, to call such a device a introtsikl in a literal sense is impossible, as the inner rim it is connected to the trolley and is used as an external mover.
 
The first tests of our offspring confirmed the accuracy of the approach to its design (however, errors and rework was still a lot). Today the car, with a mass of 80 kg and engine power of 1.3 HP at speeds up to 35 km/h, has a good load capacity (100 kg), stability and maneuverability.
 
The basis of design — the wheelbarrow and the truck, pivotally connected by a swivel carriage. The first has internal and external ribs mutually held relative to each other one leading and three free rollers. On the inner rim of the engine with the gas tank, parts of the steering system and the driver’s seat.
The most difficult to manufacture the wheel was the outer rim. This is because the basis was taken from the decommissioned aircraft turbojet engine titanium ring. It is implemented by others, bent from two identical aluminum profiles, fastened with steel strip. To connect profile and titanium rings to the steel strip in the area of the ends temporarily welded tendor that after heavy compression rings and welding of the joint strip has been cut. As “tires” wheels used rubber conveyor belt, which throughout its length is attached to the rim evenly spaced bolts. To the left (while moving) the profile of the rim is inserted a steel fingers with a diameter of 5 mm, designed for coupling with a driving gear of a leading roller.
 
MAG wheel consists of three sections of the inner rim and the rollers. Sections are connected by bolts, two of which simultaneously serve as rollers loose rollers. Latest rotate on bearings mounted on shafts via eccentric, the ends of which are cut the grooves for the splines retaliatory restrictive bushings. This design allows you to adjust the position of the rollers relative to the outer rim, it is only necessary to turn the eccentric bushings restrictive. Section rim made of standard duralumin tubes of rectangular section and door profiles.
 
The connection of the drive wheel with a rotatable carriage made in the form of a kind of “spider”, where the “feet” of the brackets and thrust, and “body” — the body of the carriage. This system securely holds the wheel while driving straight ahead and when cornering, when there are additional transverse forces. To the “spider” attached and the visor of the passenger.
 
Truck like sporty horse-drawn carriage used on the run. It consists of an axle with wheels from the map and stand United by three pairs of rods and ucoin. Strut, welded of the two steel pipes, in turn connected by two pairs of rods and struts with the bearing of the rotary carriage. On the trolley there is a passenger seat and footrest-flap, serving for fastening cable ends to the control system machine.
 
The bridge truck is a beam (tube) of rectangular cross section. In its cavity is inserted and tightened with two bolts, axles wheels. Drilled rail holes for mounting rods, ucoin, arc seat and footrests.
 
The rotary carriage plays a role as a hinge and rotation mechanism, due to the fact that its shaft is installed adrenopause disk that performs the function of the lever under the tension of the cable.
 
The D6 engine is fitted with forced air cooling, shortened pipe to the muffler and adapted to run from the starter chainsaw “Friendship 4”. To the inside of the rim it is attached with the platform and welded to it two simulators bike frames. To adjust chain tension on the platform there are tools that allow you to move it relative to the rim.
 
Air-cooled engine is provided by the installation on the small gear (from the clutch) instead of a puller of a simple centrifugal blower in the casing, and the launch of the starter motor — replacement of knot of fastening of the eccentric on the lid plugs the ratchet.
 
The torque from the engine is transmitted by the chain on the gear (z=29) of the leading roller. The second presenter (z=33) the gear engages with the fingers outer rim, thereby bringing it into rotation.
 
System the machine control cable. It consists of steering, the steering of the drum, guide rollers adrenopause disk and tether tandora to adjust its tension. All units installed on the inside of the rim, with the exception of adrenopause drive. The cable wound on the drum, passes through the guide rollers, adrenopause encircles the disk and is fixed on the bottom surface of the footrests-flap.
Unfolding torque is generated on the wheel. The stress from it is reduced drum changes its direction on the rollers and works on the shoulder, equal to the radius adrenopause drive. While the drum rotates, shortening one and lengthening the other branch.
 
Inhibition of introtsikl is a device similar in design to the brake child’s Bicycle is the type of “Bunny”. The force, created by the installed on the wheel arm, is transmitted by cable to the pad, clinging to the inner surface of the outer rim of the front wheel.
 
The appearance of our car on the street still causes great interest among children and adults. And how much joy she brings to those who manages or rides just a passenger!
