Audi prid\u00e1 e\u0161te tento rok do svojej ponuky nov\u00e9 \u013eahk\u00e9 pru\u017einy podvozku zo sklolamin\u00e1tom zosilnen\u00fdch plastov (GFK). Tie bud\u00fa k dispoz\u00edcii v\u00a0modeloch vy\u0161\u0161ej strednej triedy.<\/p>\n

Pru\u017einy GFK vyv\u00edjala Audi spolo\u010dne s talianskym dod\u00e1vate\u013eom a u\u017e na prv\u00fd poh\u013ead sa l\u00ed\u0161ia od oce\u013eov\u00fdch pru\u017e\u00edn. S\u00fa svetlozelen\u00e9, maj\u00fa hrub\u0161\u00ed priemer pletenca vl\u00e1kien (ako u oce\u013eovej pru\u017einy\u00a0priemer dr\u00f4tu), vonkaj\u0161\u00ed priemer je pri ni\u017e\u0161om po\u010dte z\u00e1vitov v\u00e4\u010d\u0161\u00ed. \u010do je ale najhlavnej\u0161ie, s\u00fa o 40% \u013eah\u0161ie ako oce\u013eov\u00e9. To znamen\u00e1, \u017ee ak\u00a0jedna pru\u017eina toho ist\u00e9ho modelu vy\u0161\u0161ej strednej triedy m\u00e1 2,7kg v oce\u013eovom preveden\u00ed, tak GFK pru\u017eina m\u00e1 pribli\u017ene 1,6kg a to pri t\u00fdch ist\u00fdch vlastnostiach. V\u00fdsledn\u00e1 u\u0161etren\u00e1 hmotnos\u0165 v\u0161etk\u00fdch \u0161tyroch pru\u017e\u00edn je a\u017e 4,4kg.
\n\u010c\u00edslo je e\u0161te kraj\u0161ie, ke\u010f si uvedom\u00edme o ak\u00fa neodpru\u017een\u00fa hmotu sa jednalo.<\/p>\n

Jadro GFK pru\u017e\u00edn tvoria dlh\u00e9, navz\u00e1jom skr\u00faten\u00e9 sklenen\u00e9 vl\u00e1kna ponoren\u00e9 v epoxide. Okolo tejto p\u00e1r milimetrov hrubej “du\u0161e” obkr\u00fati stroj \u010fal\u0161ie vl\u00e1kna striedavo v uhle\u00a0+45\u00b0 a -45\u00b0 ku smeru hlavn\u00e9ho vl\u00e1kna. Tieto \u0165ahov\u00e9 a tlakov\u00e9 smery sa navz\u00e1jom podporuj\u00fa a vytv\u00e1raj\u00fa lep\u0161iu rovnov\u00e1hu medzi p\u00f4sobiacimi silami na celkov\u00fa pru\u017einu.<\/p>\n

GFK pru\u017einy mo\u017eno nastavi\u0165 presne na p\u00f4vodn\u00e9 vyu\u017eitie oce\u013eov\u00fdch pru\u017e\u00edn\u00a0a ich materi\u00e1l pon\u00faka vynikaj\u00face vlastnosti. Nekoroduj\u00fa, n\u00e1razy kamienkov a vplyv soli a \u010distiacej ch\u00e9mie (pri myt\u00ed) neexistuje. Dokonca je vraj aj v\u00fdroba menej n\u00e1kladn\u00e1 ako u oce\u013eov\u00fdch pru\u017e\u00edn.<\/p>\n

Ak s\u00fa teda skuto\u010dne tak dobr\u00e9 a bez z\u00e1sadn\u00fdch\u00a0ved\u013eaj\u0161\u00edch negat\u00edvnych vlastnost\u00ed (aj ke\u010f hne\u010f vid\u00edm probl\u00e9m s recykl\u00e1ciou a nie je uveden\u00e1 \u017eivotnos\u0165 takejto pru\u017einy! – preto\u017ee na plast omnoho viacej p\u00f4sobia teplotn\u00e9 zmeny ako na kov a taktie\u017e\u00a0aj vek) tak nov\u00e1 \u00e9ra\u00a0pru\u017eenia podvozkov pr\u00e1ve za\u010dala a obrovsk\u00e9 plus by mohli v takejto technol\u00f3gii vidie\u0165 pr\u00e1ve v\u00fdrobcovia motocyklov.<\/p>\n
