Technical Report The Construction of Alloy Wheels :: Design and Technology

Technical Report The complex body part of stretch WheelsIntroductionAluminium mixture wheels are now utilize in all branches of Motor Racing,ranging from Touring cars and Rally cars to Formula One cars. TheAlloy wheels offer far superior mechanical properties than theconventional steel wheels formerly utilize. These benefits includereduced un-sprung weight, i.e. not held by the suspension, providingmore precise way input and improved responsiveness.Alloy wheels also improve acceleration and braking ascribable to thereduction of weight. The added strength of a quality alloy wheel bedsignificantly reduce wheel/tire deflection in cornering. This is in particular critical with a vehicle equipped with high performancetires where lateral pass forces may approach 1.0g. The metals in alloywheels are excellent conductors of come alive - improving heat dissipationfrom the stops - reducing risk of brake fade under demandingconditions. Additionally, alloy wheels can be designed to s tand moreair to flow over the brakes, this can help cooling.The alloy used in the finest road wheels today is a blend of aluminumand other elements. The term mag wheel is sometimes incorrectly usedto describe alloy wheels. Magnesium is generally considered to be anunsuitable alloy for road usage due to its brittle nature andsusceptibility to corrosion.Nowadays, at that place are basically three ways in which alloy self-propellingwheels are constructed. The three types can be referred to simply bycast, railway line and forged.Casting is a relatively inexpensive way to produce a high-quality,fairly strong alloy wheel many aftermarket alloy wheels designed forstreet use are made this way. Billet wheels are machined from a solidchunk of material and forging uses intense heat and rack totransform a slug of alloy material into the final organize of a wheel.This report will focus mainly on the dramatis personae processes used.Casting ProcessesThe most common process of constructing al loy wheels is One-PieceCasting, at that place are a number of methods to do this, and the most basicis dull Casting, this process is used world wide throughout the casting fabrication and is not exclusive to alloy wheels.The Die Casting process uses a permanent mould usually made of metal,which generally means that there is high tooling costs compared toother methods of casting, but this high tooling cost is feature withlow production costs. This means that die casting is suitable forproducts with a large production number.There are four main processes in the die casting family, these areGravity Die Casting press Die CastingLow Pressure Die Casting wring from CastingGravity Die CastingThis process is the most naive of the four, the mould or die, whichis generally made in two halves, is fill with molten metal, in the
