Snowmobiles: From Rybinsk to Tiksi - through the stormy taiga


200911061800_16

"Taiga" attacks. The Taiga family of utilitarian cars of the utilitarian class has already passed its second decade, and for the new season it has been radically updated and expanded. Two-stroke engines with power from 38 to 65 hp. - now not only with air, but also with liquid cooling. In addition to the “telescope” in ski suspension, Rybinsk residents also use a lever front suspension and install tracks 500 or 600 mm wide, designed for deep snow. The reduction gear in the transmission allows you to tow hundreds of kilograms of cargo and climb snowy slopes.

Tiksi 250 does not have similar models in the markets. During the development process, a large number of different components and assemblies were borrowed from Taiga, however, in terms of technical and operational characteristics, the model is a full-fledged new machine. The same goes for off-road performance, handling and ergonomics.

The structural weight of the snowmobile has a positive effect not only on the cross-country ability of the snowmobile, but also on its maneuverability, which was significantly increased thanks to the front suspension of the lever type, a narrow track width of 380 millimeters, and a front track width of 875 millimeters.

TIKSY 250 LUX is a very comfortable car that can be driven both standing and sitting, which is explained by the high position of the steering wheel and seat. Also, this model is an ideal option for mastering the initial stages of boondocking and taking the first steps towards understanding the basic principles of driving a mountain snowmobile.

European certification for the TIKSY 250 LUX snowmobile was successfully completed, and compliance with European technical legislation and safety requirements was also confirmed. This snowmobile model has received a CE certificate of conformity, which stands for Certificate of Conformity. This certificate allowed the manufacturer to supply the car to the internal market of the European Union.

Of course, experienced snowbikers will take for granted the electric starter, separate oil supply, heated handlebar grips and gas trigger. Optimal operation of the power unit is ensured by a programmable ignition system from Ducati Energia (this is not a motorcycle company, but simply a namesake, although also from Italy). The recent use of lightweight Canadian-made plastic skis has made it possible to reduce unsprung masses, which has a better effect on the handling of the snowmobile. The gas tank volume has been increased to 50 liters, new dual headlights have been installed (instead of one) and an LED rear light is bright, vibration-resistant and durable. At the customer's request, snowmobiles of the “taiga” family can be equipped with: hydraulic brakes, LCD instrument panel, KOSO temperature sensor, rear-view mirrors.

Tungus: devices

Already in November, new items will appear for sale in the stores of official dealers of Russian Mechanics OJSC: snowmobiles “Taiga-Lux II” ST550 DR and “Taiga-Attack II” ST 551 DR. On the Lux II model, the rear suspension was modernized, while the rear of the snowmobile was raised slightly, which improved the ease of landing and geometric cross-country ability, as well as a smooth ride. The front suspension uses a linkage design, the RMZ-550 engine is installed with a larger cubic capacity and, for the first time on Rybinsk cars, with reed valves at the inlet. Modernization of the engine made it possible to remove 55 hp from it. and improved the torque characteristics (in simple terms, “low-end traction”). The instrument panel, like that of another new product - “Attack II” - is equipped with an electronic odometer.

However, the differences between “Ataka II” and other “Taiga” snowmobiles do not end with the modernization of the tidy. The front linkage suspension has been improved - the curved shape of its arms increases the travel of the skis, and therefore comfort. The levers are secured through silent blocks, which smoothes out the shocks transmitted to the snowmobile body. The increased ski track significantly improved the stability of the snowmobile at high speeds and made it easier to maneuver. For ease of landing, footrests are installed on the floor. The expression of the plastic “face” has become more aggressive. And finally, “Attack II” received a liquid-cooled RMZ-551 engine with a thermostat and snow radiators. The pistons and crankshaft are protected by an anti-friction coating, the tuned intake system is with check plate valves and a receiver, and five-channel cylinder purging is used. The engine is equipped with a microprocessor ignition system with programming capabilities, and the drive units are driven by a transverse shaft.

Snowmobile "Tungus"


The promising Tungus snowmobile is waiting for better times.

Tiksi is the answer to the crisis. Lightweight single-seat Tiksy ST 250 is a different beast. The snowmobile is equipped with a single-cylinder two-stroke engine RMZ-250 with a power of 22 hp. (fuel - A-92 gasoline, fuel tank volume 28 liters). To simplify and lighten the machine, the designers abandoned the separate lubrication system. Removable side panels provide easy access to the units. Compact single-link front suspension - with two lightweight plastic skis. The rod-reinforced track suspension (3170x380 mm) has a pneumohydraulic shock absorber. The efforts of the engineers were not in vain: the weight of the machine was significantly reduced, and therefore the pressure per unit area, so the snowmobile is able to walk on snow of any depth and density. The Tiksi's load capacity is 120 kg, the towed trailer's weight is 150 kg, and the device is equipped as standard with a towing device for towing a sled. The new product compares favorably with other company machines (not to mention foreign “classmates”) due to its moderate price (about 125,000 rubles) and economical operation.

Specifications

"Tiksi 250 Lux" has a convenient control system with a mechanical braking system installed on the caterpillar drive shaft. It is possible to operate the equipment both in a sitting position and standing. The design of the driver's seating area is equipped with a comfortable seat and a high steering wheel, which allows minimizing the load on the joints and not getting tired for a long time. The model also provides electric heating of the steering handle.

The machine is started using an electric starter and manual start, which is very convenient. The Tiksi 250 Lux is equipped with a rear suspension with multiple levers, providing comfort when moving, during which there is no vibration. The fairly stable technology has sensitive steering.

The Tiksi 250 Lux snowmobile has a laconic, strict design and is distinguished by high-quality assembly. The machine is covered with impact-resistant plastic, eliminating the possibility of mechanical damage. For transporting goods, the equipment is equipped with a special towbar and luggage rack.

Chassis

The equipment is equipped with a single-lever front suspension with a single-tube hydropneumatic shock absorber, the travel of which is 160 mm. The rear suspension of the snowmobile is of the slip type with the same shock absorber and a stroke of 300 mm.

Snowmobile "Tiksi"

In general, the company has experience in developing machines of this class. Back in 2002, the presentation of the Taiga-250 model (“Moto” No. 2–2002) took place. But it did not go into mass production - it seemed that such “budget” cars were no longer suitable. Now times are different, and a light and cheap all-terrain vehicle had to be created virtually from scratch. A pilot batch (five pieces) of Tiksi snowmobiles was produced back in 2008. The testers, out of duty, tried to “kill” them, but they couldn’t; and the mileage of each car exceeded 4000 km. Over the summer, the designers eliminated the identified shortcomings, and now the first batch of this year is approaching: 250 pieces. It is significant that part of it has already been ordered due to the affordable price of the snowmobile. So meet Tiksi in November in dealer stores.

Design Features

All structural elements are technically designed to ensure safe use of the machine. The advantages of a snowmobile of this model are:

  • easy handling and maneuverability provided by stable plastic skis and simple front suspension;
  • convenient control mode - adjusting forward movement through one variator gear and switching back through electric reverse;
  • accessibility to components and assemblies of the structure, ensured by removable sidewalls;
  • quite a large power reserve. The 28-liter fuel tank is designed for a minimum range of 100 km;
  • a comfortable seating area for the driver with a wide supporting surface is provided to increase comfort when operating the equipment;
  • solid load capacity and the presence of a coupling device.

The Tiksi 250 Lux snowmobile has practically no disadvantages. Refinement of the basic version made it possible to create a universal model that can compete with analogues made in Europe and China. The machine is a patented certified product that has confirmed its compliance with the necessary requirements of European legislation. A CE certificate issued for a snowmobile gives the right to enter the internal market of the European Union. Moreover, there is no snowmobile of similar modification in terms of technical equipment and control from any manufacturer in the whole world.

Taiga

Was Tungus ahead of its time? However, the most ambitious development of Russian Mechanics is Tungus, a fifth-generation machine (as it is called by analogy with the aircraft technology dominant at NPO Saturn, which includes RM). Several prototypes have now been built. They paraded at the cross-country skiing World Cup in Demino, Yaroslavl region, in the winter of 2009. Well, the European debut took place at the prestigious specialized exhibition of alpine technologies INTERALPIN-2009 at the end of April in Innsbruck. By the way, all the world's snowmobile manufacturers took part in the Austrian show, and the appearance of the Russian company led foreign manufacturers, if not into shock, then into confusion. And there was a reason: a car with an unusual design is equipped with one of the most modern four-stroke engines, not inferior in its parameters to such a leader as Polaris. The supplier of the unit is Weber. The Tungus's two-cylinder 850 cc fuel-injected engine produces an impressive 80 hp. The cooling system is dual-circuit: in addition to the commonly used snow heat exchangers, an air radiator with an electric fan is installed under the hood. This eliminates all cooling problems when driving on ice or dense snow and when towing heavy sleds at low speeds. Or, conversely, when realizing the power of the entire “herd” - moving at speeds of up to 160 km/h.

Engine

The Tiksi 250 Lux snowmobile is equipped with a RMZ-250 gasoline engine. This power unit has only one cylinder, the working volume of which is 0.249 liters. A Mikuni model carburetor is used, which is found in almost all models of the Russian Mechanics manufacturer. The rated output power of this power plant reaches 16.18 kilowatts, which translates to 22 horsepower. The figure, of course, is quite small, however, given the structural weight of the snowmobile, the dynamics and traction force are quite excellent. The cooling system is exclusively air type, which is why proper operation of the machine is possible only at low ambient temperatures. The unit runs on gasoline not lower than AI-92. The lubrication system is joint, namely a mixture of gasoline and oil is used.

Variator "Tiksi"


The Tiksi variator unit has been developed “again”; the mechanically driven brake has been moved to the caterpillar shaft.

However, given the economic crisis, the management of the Republic of Moldova made a difficult decision: not to produce the expectedly expensive Tungus in the 2009–2010 season. Perhaps, if the economic situation improves, he will “get back into action” next season.

Snowmobile track


A lightweight bogie and the narrowest track possible are used: reasonable solutions for a lightweight snowmobile.

Nevertheless, we will try, as soon as the snow falls, to try out all the new products - the promising Tungus, the down-to-earth Tiksi, and the new modifications of the Taiga. Follow the publications!

PS We anticipate a reasonable question: “Well, what about Buran?” Is the smoking room alive? This model is a special theme, so to speak “Buran” - forever! Its production (and these are as many as five models) accounts for ¾ of all RM cars. A year ago, the device was once again modernized, and in the foreseeable future they are not going to curtail production of the “hard worker”...

Price

The cost of the new Tiksi 250 snowmobile directly depends on the following factors: year of production, version (basic or modified), and, of course, equipment. The price of the basic version as standard starts, as a rule, from 169 thousand Russian rubles. The cost of the modified version of Tiksi 250 Lux starts from 199 thousand Russian rubles.

Used equipment can cost anywhere from 145 thousand rubles to 180 thousand Russian rubles. In this case, the final price of the snowmobile is influenced by the year of production, general technical condition, and the number of kilometers traveled.
