To kolo Hyundai ima vgrajeno snežno verigo, ki izskoči

Hyundai has come up with a solution to get rid of traditional snow chains. It’s called a shape memory alloy snow chain and it replicates the functionality of traditional snow chains at the touch of a button. How does it work? The newly developed wheel and tire assembly has built-in radial grooves at regular intervals. There are shape memory alloys inserted into these channels, making the assembly look like a pizza.

When an electrical signal is received, the shape memory alloy modules protrude to behave like a snow chain. The elements sticking out of the rubber form a “J” shape to improve grip on a slippery surface during wintertime. When not in use, the shape memory alloy resides within the wheel in the shape of an “L” that doesn’t touch the road surface.

Inevitably, the tire will be worn down to the point where those alloys will always make contact with the road surface. That’s when the tire will have to be replaced. Hyundai omenja, da je zaprosil za patent doma v Južni Koreji in tudi v Združenih državah. Medtem že ima načrte za nadaljnji razvoj tehnologije. Če šlo vse po načrtih, Hyundai in Kia bo razmislil o uvedbi snežnih verig iz zlitine s spominom oblike v množično proizvodnjo.

Ostaja pa eno vprašanje: koliko bi to stalo? In zdaj, kako draga bi bila sama pnevmatika, pa tudi koliko bi stala zamenjava glede na to, da se zlitina s spominom oblike začne blizu središča kolesa? Vse to bomo še videli.
