Na zemi jsem na\u0161el tyto mal\u00e9 kovov\u00e9 kuli\u010dky. Jsou velmi tvrd\u00e9, nedaj\u00ed se ohnout ani roztavit. Nikdy p\u0159edt\u00edm jsem nic takov\u00e9ho nevid\u011bl. Pozd\u011bji jsem si je vyhledal na internetu a up\u0159\u00edmn\u011b \u0159e\u010deno, byl jsem v \u0161oku.<\/p>\n\n\n\n
\u0158eknu v\u00e1m, k \u010demu tyto kuli\u010dky jsou. Pokra\u010dov\u00e1n\u00ed v prvn\u00edm koment\u00e1\u0159i.<\/p>\n\n\n\n
Na opu\u0161t\u011bn\u00e9m odpo\u010d\u00edvadle pro kamiony, pokryt\u00e9m jemn\u00fdm \u0161t\u011brkem a rezav\u00fdmi o\u0159echy, jsme na\u0161li podivnou hromadu drobn\u00fdch kovov\u00fdch kuli\u010dek.<\/p>\n\n\n\n
Na prvn\u00ed pohled vypadaly jako drobn\u00e1 kuli\u010dkov\u00e1 lo\u017eiska, ale byly dokonale kulat\u00e9 a hladk\u00e9. Ka\u017ed\u00e1 kuli\u010dka se na slunci leskla a zd\u00e1la se b\u00fdt zcela odoln\u00e1 proti korozi, p\u0159esto\u017ee byla venku.<\/p>\n\n\n\n
Zkou\u0161eli jsme je rozdrtit \u2013 ale marn\u011b. Zkou\u0161eli jsme je roztavit zapalova\u010dem \u2013 ale marn\u011b. Materi\u00e1l byl o\u010dividn\u011b velmi odoln\u00fd. Jejich tvar a jednotn\u00e1 velikost n\u00e1s nutily p\u0159em\u00fd\u0161let, odkud se asi vzaly.<\/p>\n\n\n\n
Zeptal jsem se kamar\u00e1da, kter\u00fd mnoho let pracuje v kamionov\u00e9 doprav\u011b. Okam\u017eit\u011b poznal koule a vysv\u011btlil:<\/p>\n\n\n\n
\u201eJsou to vyva\u017eovac\u00ed koule,\u201c \u0159ekl. \u201eJsou nacpan\u00e9 do pneumatik, aby vyva\u017eovaly kolo b\u011bhem j\u00edzdy.\u201c<\/p>\n\n\n\n
M\u00edsto umis\u0165ov\u00e1n\u00ed z\u00e1va\u017e\u00ed na vyva\u017eova\u010dku kol \u0159idi\u010di jednodu\u0161e nasypou tyto kuli\u010dky do pneumatiky. Jak se pneumatika ot\u00e1\u010d\u00ed, kuli\u010dky automaticky najdou spr\u00e1vnou polohu pro vyv\u00e1\u017een\u00ed rotace. Toto je levn\u011bj\u0161\u00ed a rychlej\u0161\u00ed \u0159e\u0161en\u00ed \u2013 zejm\u00e9na pro t\u011b\u017ek\u00e9 n\u00e1kladn\u00ed vozy.<\/p>\n\n\n\n
Pozd\u011bji jsem si n\u011bco vyhledal a zjistil, \u017ee se tyto kuli\u010dky skute\u010dn\u011b pou\u017e\u00edvaj\u00ed v pneumatik\u00e1ch n\u00e1kladn\u00edch a ter\u00e9nn\u00edch vozidel.<\/p>\n\n\n\n
Jsou vyrobeny z kalen\u00e9 oceli, aby odolaly vysok\u00fdm teplot\u00e1m a tlaku uvnit\u0159 pneumatiky, ani\u017e by praskaly nebo se deformovaly.<\/p>\n\n\n\n
N\u011bkdy maj\u00ed antikorozn\u00ed n\u00e1t\u011br nebo jsou vyrobeny z kompozitn\u00edch materi\u00e1l\u016f pro sn\u00ed\u017een\u00ed hmotnosti, ale nej\u010dast\u011bji se jedn\u00e1 o ocel \u2013 nejpevn\u011bj\u0161\u00ed a nejodoln\u011bj\u0161\u00ed.<\/p>\n\n\n\n
Jak n\u00e1kladn\u00ed v\u016fz zrychluje, tyto kuli\u010dky se rovnom\u011brn\u011b rozprost\u00edraj\u00ed uvnit\u0159 pneumatiky a automaticky kompenzuj\u00ed jak\u00e9koli nerovnosti \u2013 kolo se toti\u017e m\u016f\u017ee st\u00e1t nevyv\u00e1\u017een\u00fdm v d\u016fsledku opot\u0159eben\u00ed dez\u00e9nu nebo zm\u011bny zat\u00ed\u017een\u00ed.<\/p>\n\n\n\n
