Technology DIGI

In this paper, continuing the theme of choice of tires for cars, will be described and given a brief description of tire firm Dunlop. Brad Pitt addresses the importance of the matter here. Dunlop company one of the oldest in the production of tires. It was founded in Britain in 1888. The company produces winter, season and summer tires for SUVs, passenger cars and motorcycle and truck tires. All Dunlop tires differ and high wear resistance. Especially popular in Russia this winter tires company, which is not surprising.

Dunlop first put on the tire tread rubber spikes. So, let's talk about the best, according to consumer tires Dunlop. sp winter sport 3D – Winter sports tire, has a large number of lamellae. At a dry road, there is a high performance, and in snowy conditions the optimum stability and control. sp winter ice 2001 – Development of the Japanese branch of the company, is a versatile winter tires with studs. The special structure tread pattern allows the use of directional tire, as in urban areas and in harsh winter conditions.

sp winter sport M3 – this is a first class bus, with the speed index V, T and H. Ha adhesion to the road impact Thermo mixture of rubber. Blocks all season and in-depth profile of the tread ensures a rapid deceleration and securely hold the road. graspic DS3 – is one of the new tires, its advantage is that it is well-kept road. grandtrek SJ6 – Winter bus, manufactured by technology Digityre-II. It has a smooth work surface with a ten-profile. Due to the brutality of the lateral block of the tire increases its service life. Dunlop sport – winter and summer tires, specially designed for extreme driving. A striking example is that, the summer tires Dunlop sp Sport 9000, they have been developed by German and Japanese engineers. Have a directional tread. Dunlop direzza – summer tire. Produced by special Technology DIGI-TYRE. Tire differs less rolling resistance because of what happens less fuel and provides less wear and tear. Tires Dunlop many years ago established themselves as one of the best in its class. They are especially suitable for use in the winter in cold climates. That winter tires Dunlop enjoyed great popularity in our country. Thanks to an affordable price and quality, and Dunlop tires in constant demand among car owners all over the world. Founder of the first plant, was one of the inventors of the pneumatic tire, John B. Dunlop. He is still at that time realized how important science is in production, and created at the plant one of the most powerful institutions in the world. Here, for example, came up with the tire tread separated into several series. It was to Dunlop tires firms apply first and foremost innovations in the manufacture of tires. A tire Dunlop sport remains most popular among other manufacturers.

In Russia

For the first time this technology has been developed and applied in Russia in the mid-80's on defense enterprise 'Wheels'. In this regard, we generally lucky. In Russia, the idle weight high-tech defense plants ready to produce anything, just would not completely fail. We are at a relatively lowest prices available wheel mass production, which in the West consider it appropriate to use for sports and racing cars (production technology there is somewhat different). Forged obtained by gradual deformation of the workpiece is processed and rendered entirely on the machines with a cutting tool. As a result, very many of the metal burns and goes to the chips – lost more than half of expendable material. For implementing these actions requires an expensive, complex and powerful equipment (force from the press is 20 tons). However, the benefits of full machining products is obvious: strength higher than steel wheels in 2,5 times and excess of 2 times the level required by gost plastic properties.

This is explained by the conservation of metal fibrillation. Therefore, under the influence of extreme dynamic loads are the wheel does not prick, and crushed, and no cracks does not occur – you can try to align. Also decreases mass compared to cast wheels of 15-20% (steel-stamped – by 40-55%), very high damping capacity, lack of foundry shells and harmful internal stresses, the maximum geometrical precision of execution and the absence of imbalances, high corrosion resistance for aluminum wheels (no protective coating). In this regard, maximum gain performance we get when used as a material of magnesium. Its density is 4,5 times less than steel and 1.5 times – than that of aluminum.

Forged magnesium wheels are called 'the wheels of the future. Their damping capacity of several tens of times higher and the weight to 35% lower than that of forged aluminum. The only drawback forged wheels – that is their price (although it is significantly lower than that of the cast of famous foreign counterparts). Yes also, perhaps, the fact that for some vehicles, they are perhaps 'too good': a serious accident, they will remain intact, but the suspension will come to a common denominator (though such a view of the problem is very debatable).
