N\u00e4r vi byter fr\u00e5n fossildrivna bilar till elbilar \u00e4r det inte bara tankningen som byts ut mot laddning. Det finns \u00e4ven andra saker man kan beh\u00f6va t\u00e4nka p\u00e5, som till exempel vilka bild\u00e4ck elbilen har. Det visar sig n\u00e4mligen att elbilar fungerar annorlunda och kr\u00e4ver andra d\u00e4ckegenskaper.<\/strong>

Vi informerar om de tre viktigaste sakerna att t\u00e4nka p\u00e5, samt om nya material i bild\u00e4ck till elbilar. Snabbl\u00e4nkarna nedan tar dig direkt till det som mest f\u00e5ngat ditt intresse:<\/p>\n\n\n\n

Motst\u00e5ndet p\u00e5verkar r\u00e4ckvidden<\/h2>\n\n\n\n

Rullmotst\u00e5ndet \u00e4r det allra viktigaste n\u00e4r det g\u00e4ller att spara p\u00e5 r\u00e4ckvidden hos elbilar. H\u00e4r har \u00e4ven bilens tyngd stor betydelse. (Se nedan.) N\u00e4r elbilarna rullar p\u00e5 v\u00e4garna kan d\u00e4cken v\u00e4rmas upp, s\u00e5 kallad vulkanisering<\/strong> uppst\u00e5r, men de v\u00e4rms s\u00e4llan upp lika mycket vilket skapar olika stort motst\u00e5nd. Detta kan undvikas om d\u00e4cken \u00e4r speciellt anpassade f\u00f6r elbilar.

D\u00e4ck med l\u00e4gre rullmotst\u00e5nd kan \u00e4ven anv\u00e4ndas p\u00e5 bensin-, diesel- och hybridbilar, vilket g\u00f6r att du sparar drivmedel<\/strong>. H\u00e4r spelar ocks\u00e5 bilens storlek in. En st\u00f6rre bil som en SUV har rent naturligt ett st\u00f6rre rullmotst\u00e5nd \u00e4n en liten Smart.<\/p>\n\n\n\n

\u00c4ven tyngden p\u00e5verkar r\u00e4ckvidden<\/h2>\n\n\n\n

En elbil \u00e4r som regel upp emot 30 % tyngre \u00e4n bensin- och dieselbilar. En personbil allts\u00e5. Ju st\u00f6rre fordonet \u00e4r desto h\u00f6gre vikt<\/strong>, och desto kortare blir r\u00e4ckvidden. B\u00e5de h\u00f6g vikt och h\u00f6gt motst\u00e5nd inneb\u00e4r ocks\u00e5 att d\u00e4cken slits fortare. D\u00e4rf\u00f6r har m\u00e5nga stora d\u00e4cktillverkare tagit fram nya d\u00e4ck och nya gummiblandningar som klarar st\u00f6rre p\u00e5frestningar. D\u00e4ckens konstruktion \u00e4r ocks\u00e5 annorlunda.

F\u00f6r att spara p\u00e5 d\u00e4cken kan du h\u00e5lla koll p\u00e5 elbilens lastindex<\/strong>. Du hittar information om hur du g\u00e5r tillv\u00e4ga i bilens manual. Viktigt \u00e4r att du aldrig belastar d\u00e4cken mer \u00e4n det till\u00e5tna v\u00e4rdet!<\/p>\n\n\n\n

Ljudet fr\u00e5n bild\u00e4cken p\u00e5verkar k\u00f6rupplevelsen<\/h2>\n\n\n\n

En elbil \u00e4r betydligt tystare \u00e4n en bensin- eller dieselbil; motorn st\u00e5r bara f\u00f6r 15% av bullret. Vissa elbilar h\u00f6rs knappt alls n\u00e4r de susar fram p\u00e5 v\u00e4garna. Det som h\u00f6rs \u2012 och d\u00e5 framf\u00f6r allt inne i bilen \u2012 \u00e4r ljudet fr\u00e5n bild\u00e4cken (40%) och vindbruset (30%). N\u00e4r bilen i sig blir tystare kan detta morrande snabbt bli irriterande. H\u00e4r st\u00f6ter vi dock p\u00e5 en mots\u00e4gelse.

Om d\u00e4ckens kontaktyta mot asfalten minskar, ja d\u00e5 minskar inte bara ljudniv\u00e5n utan \u00e4ven v\u00e4ggreppet. F\u00f6r att d\u00e4mpa bullerniv\u00e5n har man uppfunnit en annan typ av d\u00e4ckm\u00f6nster som avleder ljud<\/strong>. \u00c4ven inuti d\u00e4cken har man lagt in en slags matta som absorberar ljud. P\u00e5 s\u00e5 vis blir k\u00f6rupplevelsen mer behaglig. <\/p>\n\n\n\n

Nya material i framtidens bild\u00e4ck<\/h2>\n\n\n\n

Man skulle kunna tro att det \u00e4r det snabbare accelererandet som g\u00f6r att elbilarna kr\u00e4ver starkare bild\u00e4ck. Det har med saken att g\u00f6ra, men tydligen spelar vridmomenten vid k\u00f6rningen<\/strong> st\u00f6rre roll. \u00c4ven den djupare tyngdpunkten, d\u00e5 batteriet \u00e4r l\u00e5gt bel\u00e4get, kan inneb\u00e4ra att d\u00e4cken beh\u00f6ver andra egenskaper.

Den st\u00f6rsta skillnaden p\u00e5 d\u00e4cken f\u00f6r elbilar och “vanliga” d\u00e4ck \u00e4r att man f\u00f6rst\u00e4rkt d\u00e4cksidorna f\u00f6r att de ska klara av skarpa kurvor och andra vridmoment. I det fortsatta utvecklingsarbetet kommer \u00e5tervinning f\u00e5 en st\u00f6rre plats, och inte bara av gummi. Man har till och med b\u00f6rjat titta p\u00e5 hur man kan anv\u00e4nda \u00e5tervunnet material fr\u00e5n PET-flaskor<\/strong> vid d\u00e4ckframst\u00e4llningen. The sky is the limit, som man brukar s\u00e4ga.<\/p>\n\n\n\n
