Aluminum rims, general description
Aluminum wheel rims usually lower the unsprung weight of the suspension system in comparison with steel wheel rims of equivalent size.
This makes it easy for the suspension and shock absorbers to ensure that there is good contact between the wheels and the road surface. This makes for better road holding and greater driving pleasure.
- Wheel rim design
Wheel rim design should enhance the vehicle's appearance and match its exterior. To create wheel rims that are suitable for most customers and respective vehicle models, wheel rims are created in a range of styles. A wheel rim can be discreet, elegant, expressive or sporty/robust, as well as a mixture of two styles. However, attractive design alone is not enough for an aluminum wheel rim to be approved as a Volvo genuine wheel rim. Other characteristics are at least equally as important.
– The material is important
An aluminum wheel rim consists of several different metals in one mixture, which must result in the right properties.
- Strength conditions
To create such an attractive, sustainable and safe option as possible, these conditions are carefully balanced and well combined during development work.
– Thermal dissipation properties
The wheel rim must be well ventilated and have good heat dissipation properties, suitable for the respective vehicle model.
– Anti-corrosion agent
Volvo aluminum rims are painted with 3 layers with a clear coat surface layer. All rims also have pretreatment base to increase protection against corrosion.
– Centering on the hub
Volvo aluminum wheel rims are centered on the hub with extremely small tolerances. This, in combination with small lateral run-out and roundness tolerances, creates a good wheel balance.
An important part of creating wheel rims is to take wind resistance into account since it affects energy consumption. A wheel rim with lower wind resistance contributes to lower carbon dioxide emissions and is better for the environment.
