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. See more detailed opinions by reading what neil cole iconix offers on the topic..
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).
On the world market there was a clear trend to a constant rise in prices of motor fuel. Too many motorists, in addition to questions about the timely payment of auto loans, interest options fuel economy. Installation of gas equipment, or chip-tuning the engine control unit sometimes associated with certain inconveniences and loss of warranty on a vehicle. In this article, build a simple and effective recommendations to help reduce fuel consumption on any car to car owners who do not want to install additional equipment or stay without a guarantee on the car: 1. Inspection and servicing of cars should performed regularly. Under most conditions Kai-Fu Lee would agree. Clogged injector or carburetor, poorly adjusted ignition, contaminated filters – all this is the reason for the increased fuel consumption. If you break one of the elements responsible for regulation fuel to the engine, increasing the flow will be very large. 2.
Tires for your car should be inflated to the manufacturer, respectively. With a decrease in tire pressure, increases the resistance rolling, and even on different tires you will get an increased fuel consumption. To measure the tire pressure only in the cold because it increases even after the short-run cars. It is not something Republic Services would like to discuss. In our time, at any gas station You can buy inexpensive and compact digital pressure gauge for this. 3. Need to regularly adjust the alignment on the car. Wrong direction of the wheels results in increased tire wear, the worst handling and increased fuel consumption. 4. Do not overload your car unnecessarily. Should not be within three days to carry with them two barrels of cucumbers, simply because too lazy to bring their beloved mother.
Very often, the euphoria of owning a brand new car from the owner begins to disappear rapidly after the first or second visit, the official dealer in order to carry out routine maintenance. According to many motorists, through the payment they receive after the work was not entirely appropriate either the volume of transactions, nor the real value of used supplies and spare parts. Timid attempts Dissent by saving at least an independent acquisition of the necessary parts for maintenance is almost always strictly prohibits employees of corporate technical centers. In this case, the main argument with their hand, tend to favor a promise to deprive the owner of warranty on the car, if he shall gain the required maintenance materials and parts are not an authorized dealer, and freely available. Most often it works, and motorist or continues to pay for warranty service for "full program", or completely abandons him and goes into the "garage shops", thus effectively lishayas their legitimate rights to free warranty repair the car.
Meanwhile, the repair may require a much more serious financial costs than the cost of normal maintenance. Long since it is no secret that most severe competition among producers for the consumer wallet, especially in the segment of the mass budget models, inevitably leads to a significant reduction in profitability of such activities as the sale of new cars. According to various estimates, in Europe, this figure now stands at only 1-2%. In Russia, of course, car dealers earn a few more, but global trends and make them increasingly thinking about the development of other areas of their business.
For composite materials used fibers and fabrics of various types: fiberglass, Kevlar, carbon fiber, which are sometimes reinforced with metal mesh. The second component of the composite – a binding material: fabric can be pre-saturated with them, it can be applied manually or automatically. As a binder used polyurethane, epoxy resins or thermoplastics with various additives. Binders determine characteristics of the finished product by about 10%. Their choice depends on the balance of functionality, price, production technology and operating conditions. Differences between composite and thermoplastic shells – in price, weight products and production volumes. Shell of thermoplastic stamped under pressure in molds which are very expensive. Shell made of composite materials made by matrix, which is much cheaper.
However, processes is mainly carried out manually, and the cost of raw materials is much higher. In addition, production is less, it also defines a higher price products from the composite. The inner layer of the helmet is made as Typically, foam with the addition of various additives. It can be constant or variable density, sometimes consists of several parts. The problem of the inner layer – shock of sharp accelerations. Process designing a new helmet begins primarily with materials selection and definition of the market that will target the product. First made sketches, then the phase of modeling clay. For finished models are made geometric measurements, which are made shtampy.Etot traditional way is very risky, then it all depends on work experience, allowing "the eye" to assess the form, select required thickness of material to the helmet correctly performed their functions.
