Kovka - volume punching - at present top of design thought in sphere of manufacture of wheels for cars. For the first time this technology has been developed and applied in Russia in the mid-eighties at defensive enterprise "Вилс". In this respect to us in general has carried. In Russia the weight of the hi-tech factories, ready to make everything stands idle if only not to go bankrupt. Under rather low prices wheels of mass release which in the West consider expedient to use only for sports and racing cars are accessible to us.
Automobile owners expect that disks from light-metal alloys are solved by two problems - improve running characteristics of the car and its appearance. However after purchase and installation of "beautiful" wheels of changes in behaviour of the car many do not find out. Why? The reason very simple - sometimes automobile owners win only in design as the weight light-alloy disks appears takojzhe, as well as at steel stamped. Running characteristics at "a native" start (as well as at regular disks) remain former, therefore you hardly will feel improvements of accelerating dynamics, work of a suspender and a braking system. And here if the start has considerably changed, some characteristics can even worsen. First of all it concerns geometry of a course of a wheel and the increased loadings on bearings of naves, and on all running.
Taking a great interest in tuning, automobile owners often aspire to put tyres with lower cross-section and the big diameter of disks from a light-metal alloy, forgetting about such important parametre, as wheel weight. The wheel as a result is frequent it turns out much more hard native that involves variety of negative consequences: loading on a detail (the stabilizer, sajlentbloki, springs) and knots (bearing parts of absorbers and amortisation racks) car suspenders because of what they wear out faster raises.
At the increased weight of a wheel, on high speeds, on a rough road surfacing the kind of work of elastic elements and absorbers changes - after arrival on a height the wheel with delay comes back to a place, and at journey of holes hangs, i.e. in both cases coupling properties with road worsen.
