On the russian market There is a huge amount of tires. Of these, a considerable part is designed for winter operation. There are more budget and expensive models. However, when choosing it is worth paying attention not only to the price, but also on the characteristics, since in winter the conditions of operation are the most complex. Continental has such tires called IceContAct 2.

They are ideal for harsh Russian winters. Their peculiarity is that properties are preserved in a heavy frost, and the perfect clutch is provided by spikes in the tread pattern. Consider this model in more detail.

Where are produced

Continental Ice Contact 2 is produced in Russia, in the city of Kaluga. Their manufacturing here began in March 2015, so the tires can be considered a novelty on the market. All production technology is the same here as in Germany at the main enterprise.

Experienced German specialists are followed by product quality, because of which defective tires will never get to the buyer. Tires are manufactured not only for the domestic market of Russia. They are also sent to Scandinavia and Baltics, where the climate in winter is similar to the Russian.

Some information about tires

CONTINENTAL ICECONTACT 2 tires are designed for passenger cars For the period of winter operation. They are presented in the second generation. Compared with the first version, they received improved indicators.

If you believe the statistics, the controllability on dry asphalt has improved by as much as 9 percent. On the ice coating, the same handling increased by only 2 percent, but this is noticeable.

Rubber mixture

The composition of the rubber in this model has been radically changed to improve properties. Now it includes elements containing silicon and special polymers. Thanks to this, the tires are capable of withstanding strong frosts, as well as maintain important properties in such conditions.

Also, due to this, the resource of tires increased, which contributes to savings, because one set is enough for a larger period.

Figure tread

Protective drawing of tires asymmetrical. It is divided into several parts for greater efficiency.

The outer part provides excellent coupling properties and controllability, and the central part is responsible for the acceleration and braking of the car. Thus, the tires provide the minimum brake path.

Spikes

The number of spikes here is limited. This was done because of strict restrictions, which were not so long ago introduced in Europe. According to them, the number of spikes on the tread must be observed, and their form is not too acute.

So it was done in order to reduce the effects of spikes on asphalt. As studies have shown, due to the special shape of the spikes, the coupling properties did not deteriorate, but the destructive effect on the road surface decreased.

How to install IceContact 2 tires

After purchasing tires, they should also be properly installed. This process is not known everything, so it will be described in more detail here.

Connect the tires and the disk is unlikely to be independently, as it is necessary for this. special equipment. However, you can install the finished wheel. There is nothing complicated in this.

You need to examine the side of the tire in more detail. It should be an outside or similar to the inscription, which means the outside of the tires.

Inside inscription inscription. When installing, you must navigate them, and then everything will be done correctly. The protector will accommodate correctly, and the tires will reveal their potential.

Outcome

Continental Ace Contact Tires Contact 2 are a good option for cars that are operating most of all in the snow and ice. It is in such conditions that they are able to secure safe driving.

And he did not know that tires are not only physics, but also chemistry, with all the consequences arising from here (this, by the way, applies to the fact of aging tires). This is the chemical component of this product and said at the Continental technical seminar.

A TASK

The place for the seminar was chosen the most that neither is the northern - polygon near the Finnish town of Levi. And the main theme of the seminar was the principle of creating optimal, from the point of view of chemistry, winter tires. It is optimal (as you know, there are no ideal tires), oriented on this or that region of use. And first of all, taking into account the temperature modes in the region itself. And for a start, everyone was asked to strike with a hammer in two samples of rubber, just extracted from the refrigeration chamber. The first sample ended up testing without a hint of residual deformation, and the second, as if the glass, split into the same time. The fact is that in the first sample there was a rubber mixture, "designed" to a temperature in -60 ° C, and the temperature threshold of the mixture of the second sample did not exceed -20 ° C. By the way, it is a good example of why when the appropriate season occurs And at a stable temperature below + 7 ° C, it is already necessary to change the summer tires on the winter.

Here they are, the Success Success: Components participating in the creation of a tire

It is the rubber mixture that is the most important variable factor on which approximately 50% of the changes in the quality of the tire depends. In total, the developers of Continental use 15 chemical components created using about 1500 different materials, various combinations of which and determine the characteristics of the tires. And the general technical task for the creators of the rubber mixture is easy enough to provide maximum possible clutch Tires with expensive under concrete weather and temperature conditions.

DECISION

And then, on the basis of all of the same technical tasks, the assembly of a kind of chemical puzzle begins. Compound allows you to provide elasticity and, accordingly, good coupling qualities? And if the wear resistance of the tire will not suffer? Try to provide enhanced information? But as far as then the tire, whose protector is inclined to "twin," will lose in his coupped properties? Technical carbon is used as so-called "fillers" in the tire industry, and 20 years ago, engineers began to use silicon dioxide (Silica) - it is they who seriously affect both the tire clutch characteristics on the wet coverage and its wear resistance. BUT optimal balance These fillers in the chemical composition of the rubber mixture of the tread is just possible to provide specified characteristics. The polymers in the composition of the rubber mixture provide rubber needed elasticity, and oils (in Continental products also use rapeseed oil) make rubber softer. As in the case of other ingredients, the amount of oil in the composition of the rubber mixture can seriously change product characteristics. And already at the vulcanization stage, the ratio of such substances such as zinc oxide and sulfur has a significant effect on the characteristics.

CONTINENTAL ICECONTACT 2 spikes withstand an increasing force in 500 N

In the course of the seminar, his participants were offered from the "components" to create an optimal compound for certain conditions, collecting the same chemical puzzle. As for the practical illustration of these chemical calculations, the following numbers can be given: if the brake path winter tires The snow covering from a speed of 50 km / h is 31 meters, then the brake route of the tires with the same compound, but the summer pattern of the tread will be already 42 meters. And just summer tires will leave 62 meters. As they say, feel the difference.

PRODUCT

The technical seminar contains both the innovations of Continental. For example, the studded IceContact model 2. As for the main theme of the seminar, the recipe for the rubber mixture of the tread in this tire was focused on lower temperatures. As in the predecessor - the Contiice Contact bus, here is an asymmetrical pattern of the tread, but the main "chip" is concluded in spikes. First, they were much more - 190 instead of 130! But what is the legislation, which regulates the installation of no more than 50 spikes on the trafficphone meter, you ask. Continental developers in this case were acted as well as their colleagues from nokian companies Tyres, which have proven special tests that an increase in the number of thickens in their product does not have a greater destructive effect on the road coating than the tires with a permitted number of spikes. The IceContact 2 bus spike itself has become smaller in size and is easier by almost 25%, and a new technology was used to fasten it in the tire protector. Spike is installed in the bus along with a small amount special compositionwhich when vulcanization reliably fixes spike.

So evolved the spikes of winter tires Continental

According to developers, such innovation increased by 400% improved the degree of bumps. The first impressions of the new tires obtained at the landfill, the most positive. First, very good efficiency when braking on ice. Secondly, when maneuvering on ice and on the rolled snow, the behavior of the tire is quite understandable, without surprises, they have a clear response to the taxi. As for the comfort, including sound, then they failed to check them on the asphalt. But the developers themselves said that they did not forget about this parameter.

In the midst of the winter season, the German tire manufacturer Continental introduced a new winter tire ContiCecontact 2. The presentation and testing of the new tire were organized behind the northern polar circle in the Finnish city of Levi. The conditions of this region can be called as close as possible to the Russian.

P on the tradition of studded tires in Russia is very popular. Remembering this, Continental decided to present all the advantages of his new product in advance. True on sale New tire will appear only by the future fall.

M Odel Continental IceContAct 2 joined the advanced developments of German engineers. First of all, the structure of the thorns of the spike called Kristall Stud has undergone. The new spike is 25% easier than its predecessor. Due to the weight, it was possible to significantly increase the number of spikes in the protective. Despite the fact that in some dimensions the number of spikes increased by 50%, the spikes are distributed in the tread in such a way as to always contact with a smooth ice surface, bypassing ice fragmented by other spikes.

About Tomethm that Continental continues to glue spikes into the seating holes, thereby ensuring their reliable fixation. Such a technology 4 times improves the degree of fixation of spikes. It is not surprising, because each spike can withstand the load up to 50 kg.

And the range also underwent tire protector, where the outer side improves stability during the passage of turns, and the internal is responsible for reliable grip during overclocking and braking. According to the statement of German specialists, compared with the first generation of ContiCecontact, the controllability of the new tire on dry roads managed to improve by 9%, on ice - by 2%. In addition, the efficiency of braking and acceleration on the ice road has improved by 8%.

About the bottom market of sales markets IceContAct 2 Continental by tradition sees the Baltic countries, Scandinavia and Russia. The next year, motorists will be offered a tire in 69 popular sizes with a landing diameter of 14 to 20 inches, and in some sizes of the tire will be produced only on russian factory Continental in Kaluga.

Alexander About Bus Continental ContiCecontact 2 Honest Feedback

In this material, we will describe in detail about the novelty of Continental IceContAct 2 and the new theologies of influencing the safety and trouble-free driving in winter conditions.

Let's start with the fact that the Continental IcecontAct 2 bus produced in Russia is newest development The concern and it comes out to the markets not only Russia, but also countries of Scandinavia and the Baltic States.

The manufacturer declares that new tires It has improved characteristics compared to the previous generation bus. Developers managed to improve the controllability on a dry road surface by 9%, and on ice - by 2%. In addition, the Continental IceContAct 2 tire guarantees increased controllability on snow-covered roads.

Most significantly - by 8% - increased indicators such as the transfer of brake and traction efforts on ice. All other qualities of a new winter tire with innovative obesity technologies regarding security remained on high levelcharacteristic of the tire of the previous generation. Due to what managed to achieve such improvements? Let's deal with together.

New CONTINENTAL ICECONTACT 2

Concern Continental conducted numerous studies in collaboration with University of Karlsruhe (Kit) and using its own drum test booth The Continental Concern's specialists developed a new method of determining the wear of the roadbed of studded tires. The results of the studies have made it possible to conclude that the spikes of smaller size and the mass are significantly less wearing the road canvas than heavier spikes. Taking the basis of these results, the Continental Concern's specialists developed for the new Tire Continental IceContact 2 new ultralight spike. The mass of new spikes is 25% less than spikes that were installed in the previous generation tire. Thus, depending on the size in a new tire, you can set 50% more spikes. Such an increase guarantees a new tire best features On Ice compared to the previous model and does not lead to greater wear of the roadway. In other words, the new tire is capable of providing a better grip with icing roads characteristic of the northern regions. An additional advantage of thickens of reduced sizes and mass is a reduced noise level from tire friction about the road.

Demonstration of spike evolution. The most extreme right spike is the smallest. It is he who is used for misses Continental IceContAct 2. Its mass is 25% less than that of the spike of the previous generation.

The location of spikes with a displacement in Continental IcecontAct 2 provides them with constant contact with intact ice, and not with ice, which has already been fragmented by other spikes. The result is an improved clutch. In order for the spikes did not stick ice, the engineers of the Continental concern developed the so-called "ice pockets", that is, small closed cavities around the spikes in which the fragmented ice accumulate before being removed under the action of centrifugal force. Such a decision leads to an increase in the level of security, especially when braking.

Concern Continental became the first tire manufacturer in the world, which developed a special technology of more reliable fixation of spikes in the tire, which reduces the likelihood of separating spikes from the tread while driving. For a small base of spikes, a special adhesive composition is applied, after which the spikes are inserted into the bus robotic machine. At the next stage of the production process, the spikes are fixed in the tire at certain temperatures and pressure. Such a technological process increases 4 times the strength of the attachment of spikes in the bus compared to the traditional one. Each thorns thus pasted withstands the load to 500 H (50 kg) without traces of the separation from the tread. Specialists of the plant proudly declare that when using CONTINENTAL ICECONTACT 2 tires for the tire operation season will not lose any spike.

The results of measurements of the effort required to break the spike from the tire tread. Green graph is a standard spike without glue. Red chart - inclined spike protector Continental IceContAct 2.

The growth of efforts to break the spike does not limit the advantages of the new technology. The inclined spike forms a single whole with the protector, and due to this, the controllability is improved and the braking path is reduced. How it works, shown in the video.

Protector Continental IceContact 2

It is worth noting that the Continental IceContact 2 bus received a new asymmetric pattern of the tread. The outer part of the tread pattern provides good clutch with an expensive and is responsible for the car handling during rotation. The inner part of the tread helps a good clutch on the snow and increases the traction force. The internal tread blocks have a large number of edges and speed slots in the protective for maximum snow collection and increasing friction on the snow. The protector is also equipped with sinusoidal lamellas with a pronounced effect of mutual closure of blocks to increase the transverse stiffness with outside. All this improves the characteristics of the tire when overclocking and braking on a snowy coating.

The videos clearly shows the work of the Winter Covered Tire Tire Continental IcecontAct 2, the lamella system and the operation of the internal engagement blocks.

Rubber mixture Continental IceContAct 2

In the story O. winter Avtorsin It is impossible to bypass the composition of the mixture. After all, rubber should provide a confident movement on dry and wet, snow-covered and iced roads. The temperature can vary from 0 degrees to values \u200b\u200bmuch lower than -30 degrees. The change in the formula of the rubber mixture is the most important variable factor, which accounts for approximately 50% of the change in the quality of the tire. To make the formula of the rubber mixture and get quality corresponding to the desired characteristics for a particular application, the developers of the Continental concern are relying on a set of chemical components, including 15 items created using approximately 1500 different materials. The most important elements are polymers (rubber), fillers, softeners and accelerators.

Continental tires include up to 15 different components.

The composition of the rubber mixture of the protector of the new studded winter tire Continental IceContAct 2 includes numerous polymers and a large amount of filler in the form of silicon dioxide. Specialists have created an adapted polymer structure for an exceptionally homogeneous mixture of polymers in combination with functionalization (BR), which improves interaction with silicon dioxide-based filler.

In addition, the rubber mixture is characterized by a high proportion of rapeseed oil, used as a softener, and the accelerators of the vulcanization process optimize the chemical structure of the composition. Due to this, the rubber mixture remains flexible at low temperatures, which guarantees the best grip with the road.

By changing the recipes of the rubber mixture of the CONTINENTAL ICECONTACT 2 winter tires, the manufacturer managed to create a larger glass transition temperature compared to the previous generation of Continental IceContAct.

On the market, the new tire will appear this year. The ruler will include 69 sizes for passenger cars and cars of the SUV class. For 2016, the replenishment of the line with new sizes is scheduled.

CONCLUSIONS

As a result, we consider the CONFINENTAL ICECONTACT 2 Winter Tires chart compared to the previous generation of Continental Icecontact.

It can be seen that the developers managed to significantly improve the behavior of the car on the ice. This was the result of using the new technology produced by Kristall Dubb spikes and distribution of rows of spikes to improve the performance characteristics on ice. For this, this manufacturer has made compliance with European road wear standards. The contribution to this characteristic was made and grooves for removing the ice crumb crushed Ice Reservoir (CIR) due to the removal of ice crumbs from the surface of the contact, as well as spike retention technology.

A noticeable increase is also visible to the controlability on the dry coating. Here, oddly enough, the technology of retention of spikes, providing greater tread rigidity, as well as the system of closing blocks during transverse displacement. Quality growth When driving in the snow, it was also possible to achieve due to the new asymmetric pattern of the tread.
