Disks perform not only a decorative function in a car. The smoothness of the ride, the load on the suspension, ventilation of the brake discs and pads depends on their correct choice. In this case, the weight of the disks is of great importance, which depends on the type of disk.
Instructions
Step 1
You can choose good car wheels knowing their main features. According to the manufacturing technology, discs are forged, cast and stamped. Forged discs used to be made of steel, but this metal was too heavy and increased the load on the suspension. The only advantage of stamped discs is their low price.
Step 2
Aluminum alloys are now used to make discs. This material is significantly lighter than steel, therefore aluminum discs are lighter and reduce the unsprung weight of the car. Ride smoothness is in direct proportion to this indicator - the less unsprung weight, the smoother the car will move. The lightweight wheel does not "puncture" the suspension even on very rough roads. It has less inertia, which increases stability and makes it easier to drive, reduces the load on the components and joints of the suspension, extending its service life. In addition, aluminum is less susceptible to corrosion, especially if various anodic coatings or high-strength varnishes on an electroplated substrate are used to cover the discs.
Step 3
Aluminum wheels are forged and cast. Alloy wheels are more popular because they are of high quality at a relatively low price. Each disc is tested, the manufacturers guarantee the absence of defects - cavities and cavities in the metal. Since the technology makes it possible to reduce metal losses to a minimum, the prime cost of alloy wheels is low. Their disadvantage is the non-directional crystal structure of the metal alloy; therefore, the walls of such disks are made thick enough to provide the necessary strength.
Step 4
Forged discs provide the necessary strength, since the metal has a fibrous structure that is not broken during the manufacture of the product. The walls of forged discs with the same strength are 20% thinner than cast ones. Since this technology is characterized by a large amount of waste, forged products are more expensive than cast ones, and this difference is quite significant.
Step 5
When purchasing discs, be guided not only by considerations of economy, aesthetics or durability. Be sure to read the Owner's Manual for your vehicle. As a rule, the manufacturer gives the clearest recommendations for choosing this accessory in it. By following them and knowing the features of each type of disc, you can easily make your choice.
