The project team has developed a design of wheels for the third prototype of the "Crimea". For each previous model of the roadster, its own unique style was also made.
The development began with a sketch and a surface model of the disk by the project designer, after which the engineers will convert it into a solid model for testing and strength calculation according to GOST.
It was decided to make a disk from an aluminum alloy due to the fact that its specific strength and stiffness are higher than that of steel. The wheel disk is made using a forged billet made of aluminum alloy 6061 (GOST 4784-97) and subsequent milling with the direct participation of the Aluminum Association.
Main characteristics of the wheel:
Width: 8 inches;
Diameter: 18 inches;
DIA: 58.5 mm.
Mechanical properties of Aluminum alloy 6061:
Hardness: HB 95;
Tensile strength: 310 MPa;
Yield strength: 276 MPa;
Elongation at break: 12%;
Modulus of elasticity: 68.9 GPa;
Poisson's ratio: 0.33.
In the near future, the roadster team will select the most suitable rubber with the help of the project partners — the network of federal KOLESO centers.
