Light-alloy wheels

Light-alloy wheels from Mercedes-Benz Accessories: In good time for the switch from winter to summer tyres at the beginning of spring, Mercedes-Benz Accessories GmbH is offering new wheel models designed to lend Mercedes vehicles an even more impressive appearance. Bichromatic wheels such as the Incenio 5-twin-spoke wheel for the SLK-Class are becoming ever more popular.

Light-alloy wheels from Mercedes-Benz Accessories: Bichromatic wheels such as the Incenio 5-twin-spoke wheel for the SLK-Class feature an interesting contrast between the apparently bare, high-sheen finish of the spokes and the main body of the wheel in a palladium silver paint finish.

Old and new Mercedes-Benz wheels: A triumphant move for light-alloy wheels: at the start of the 1970´s around 4600 wheels were sold. In 2009 the number of wheels being brought into circulation increased to around 4 million per year.

Design development: At Mercedes-Benz, high-quality wheels which match the bodywork and form a logical continuation of the design therefore play a significant role in the high  design standards of all vehicle models. At the Mercedes-Benz design centre, light-alloy wheels available either as standard or as optional extras are designed by specialists in the area which is also responsible for creating the entire exterior form of the vehicle.

Product development: In the development and testing phases, Mercedes-Benz bases its work on the  actual load profile of light-alloy wheels under real operating conditions and coor-dinates its programme accordingly. As part of this, the wheels have to pass a  comprehensive test programme which goes far beyond the statutory require-ments laid down by the German road traffic type approval law.

Product development: One of the most effective test methods for assessing a new light-alloy wheel is "ZWARP", from the German "Zwei-Axiale Räder-Prüfstand" (biaxial wheel test bench)

Product development: The so-called impact test simulates driving over an obstacle such as a kerb at an angle and should not result in any chips or leaks.  The radial impact is similar to driving over an object at high speed, and this test too should not lead to failure of the wheel/tyre system.
10C280_048
Product development: Another stress test is the rotary bending fatigue test which simulates maximum cornering. Here Mercedes-Benz wheels must reach a standard which is four times the statutory requirement.

Product development: Despite all of the technical options, subjective assessments are also important. Checks carried out by the development team include the quality of the paint  finish and the casting, the quality of the machining, the correct designation, trouble-free fitting of the valve and tyre pressure monitoring system sensors or accessibility of the valve when using air refill systems normally used at filling stations to check tyre pressure.

Product development: The bolt connection system - comprising the wheel bolts, the new light-alloy wheel and the vehicle wheel hub - is checked and if necessary optimised using a special test facility.

Computed tomography/x-rays/metallography: An important part of the development process for new light-alloy wheels are  examinations which look at the internal microstructure of the wheel, right down to atom level. This is where the latest examination methods come into play: metal microscopy, scanning electron microscope (REM), x-ray systems and computed tomography (CT) provide detailed insights.
