V prvej \u010dasti \u010dl\u00e1nku o elektr\u00f3noch<\/a> ste sa dozvedeli, \u017ee vlastne elektr\u00f3ny s\u00fa iba \u013eudovo pomenovan\u00e9 disky kolies. V druhej \u010dasti \u010dl\u00e1nku sa dozviete, \u017ee nie iba elekr\u00f3n je hlavn\u00fdm materi\u00e1lom kr\u00e1snych diskov a nemusia sa vyr\u00e1ba\u0165 iba odlievan\u00edm.<\/p>\n

Ke\u010f\u017ee v Eur\u00f3pe si ale v\u0161etci v\u00fdrobcovia dr\u017eia svoju v\u00fdrobu ako prd pod plachtou, mus\u00edme \u010derpa\u0165 z Ameriky.<\/p>\n

V Spojen\u00fdch \u0161t\u00e1toch je v\u00fdroba elektr\u00f3nov niekde inde, niekde tot\u00e1lne inde na vy\u0161\u0161ej \u00farovni. Firma Forgeline vyr\u00e1ba l\u00fa\u010dov\u00e9 disky (aj) z jedn\u00e9ho kusu polotovaru. Forgeline je v USA zn\u00e1mou firmou hlavne v\u010faka s\u00fa\u0165a\u017eiam (s\u00fa obut\u00ed na \u0161print\u00e9rskych aut\u00e1ch, tuningov\u00fdch aut\u00e1ch a pod.) a v neposlednom rade dlh\u0161iu dobu aj na be\u017en\u00fdch aut\u00e1ch.<\/p>\n

Trojkusov\u00e9 elektr\u00f3ny s\u00fa pren\u00e1dhern\u00e9, ka\u017ed\u00fd chlap to potvrd\u00ed, no osta\u0148me nohami na zemi a sna\u017eme sa pochopi\u0165 najprv v\u00fdrobu jednokusov\u00fdch diskov \u2013 monoblokov. Do Forgeline sa dokot\u00fa\u013eaj\u00fa (alebo ich dovez\u00fa) polotovary mierne pripom\u00ednaj\u00face koles\u00e1 na Flinstonovom aute. Polotovar je z materi\u00e1lu T6-6061 \u2013 hlin\u00edkov\u00e1 zliatina. Seri\u00f3zne a v\u00e1\u017ene, v\u00e1\u017ete si t\u00fato inform\u00e1ciu, preto\u017ee toto je presn\u00e9 ozna\u010denie materi\u00e1lu ktor\u00e9ho chemick\u00e9 zlo\u017eenie n\u00e1jdete aj na internete.<\/p>\n

Pre\u010do monoblok? Preto\u017ee m\u00e1 vy\u0161\u0161iu tuhos\u0165 a ni\u017e\u0161iu hmotnos\u0165 ako viackusov\u00e9 disky. S\u00fa to s\u00edce iba mierne rozdiely v hodnot\u00e1ch, ktor\u00e9 nezbad\u00e1te ke\u010f jazd\u00edte \u0161portovo po ceste. No ak m\u00e1te auto na okruhy a jazd\u00edte kolo za kolom, zmenu zbad\u00e1te na \u010dasoch a na stave disku.<\/p>\n

Polotovar z T6-6061 s hmotnos\u0165ou okolo 50kg hodia na pracovn\u00fd st\u00f4l CNC zariadenia.<\/p><\/blockquote>\n

Nakoniec s\u00fa to iba sk\u00fasenosti, ktor\u00e9 ich pos\u00favaj\u00fa vo v\u00fdvoji. Takto ich pos\u00favaj\u00fa u\u017e 50 rokov a nie je to iba gar\u00e1\u017eov\u00e1 v\u00fdroba. Je to o presnom navrhovan\u00ed modelov v CAD programoch (za \u010do s\u00fa zodpovedn\u00ed kon\u0161trukt\u00e9ri), o v\u00fdpo\u010dtoch FEA (alebo po na\u0161om anal\u00fdza met\u00f3dou kone\u010dn\u00fdch prvkov \u2013 za to s\u00fa zodpovedn\u00ed aplikovan\u00ed mechanici), o testovan\u00ed a sk\u00fa\u0161an\u00ed odstrediv\u00fdch, dostrediv\u00fdch s\u00edl, ako aj pevnosti a \u017eivotnosti. A\u017e po celom tomto procese a po nespo\u010detn\u00fdch najazden\u00fdch kilometroch na dr\u00e1hach sa za\u010dne koleso vyr\u00e1ba\u0165 a pred\u00e1va\u0165. To\u013ek\u00e9 testovanie, prer\u00e1banie, op\u00e4tovn\u00e9 po\u010d\u00edtanie a testovanie stoj\u00ed nemal\u00e9 peniaze a obrovsk\u00e9 hodiny pr\u00e1ce. Dovolili by ste si v\u0161ak vy pri takej rozbehnutej firme riskova\u0165 chybn\u00fd kus, ktor\u00fd m\u00f4\u017ee pri jazde v be\u017enej prem\u00e1vke praskn\u00fa\u0165 a sp\u00f4sobi\u0165 nehodu?<\/p>\n

\"monoblock-151\"<\/a>\"FEM\"<\/a>\"wheel\"<\/a><\/p>\n

\u010eal\u0161ou potrebou re\u00e1lneho testovania je fakt, \u017ee vstupn\u00e9 hodnoty tzv. rota\u010dn\u00e9ho testu sa nemenili v priebehu 30 rokov. Tento test m\u00e1 vyp\u013eu\u0165 v\u00fdsledky s \u00fanavou materi\u00e1lu (\u017eivotnos\u0165). Probl\u00e9mov\u00e1 je hodnota koeficientu trenia pneumatiky o vozovku 0,7. Ako aj technol\u00f3gia diskov, tak aj technol\u00f3gia pneumat\u00edk v\u00fdrazne post\u00fapila, no so vstupn\u00fdmi hodnotami nikto ni\u010d nerob\u00ed. Majite\u013e Forgeline sa ale iba pousmial a povedal, \u017ee pou\u017e\u00edvaj\u00fa vy\u0161\u0161\u00ed koeficient trenia.<\/p>\n

Polotovar z T6-6061 s hmotnos\u0165ou okolo 50kg hodia na pracovn\u00fd st\u00f4l CNC zariadenia. Po\u010das procesu obr\u00e1bania v CNC\u010dkach (fr\u00e9zovanie, s\u00fastru\u017eenie, v\u0155tanie) pr\u00edde polotovar o viac ne\u017e 80% svojej hmotnosti a n\u00e1padne sa za\u010dne podoba\u0165 na disk. Za\u010d\u00edna sa zadnou stranou, kde sa spravia osadenia, ktor\u00e9 bud\u00fa dr\u017ea\u0165 pneumatiku a pokra\u010duje sa v prednej \u010dasti, kde sa za\u010dn\u00fa \u201evyrez\u00e1va\u0165\u201c l\u00fa\u010de. Nakoniec s\u00fa e\u0161te vyv\u0155tan\u00e9 diery pre skrutky (aby koles\u00e1 dr\u017eali na aute do doby, k\u00fdm ich nechytia zlodeji do par\u00e1dy)<\/p>\n

*Pozn. disk 18×9 palcov v\u00e1\u017ei nakoniec nie\u010do pod 9kg.<\/p>\n

Nasleduje z\u00e1vere\u010dn\u00e1 f\u00e1za, pr\u00e1\u0161kovanie diskov. Pre mal\u00fd podnik je to najvhodnej\u0161ia met\u00f3da nan\u00e1\u0161ania farby na povrchy v pr\u00edpade, ak hovor\u00edme o kvalite a to si p\u00ed\u0161te \u017ee hovor\u00edme o kvalite. Nafarben\u00fd disk mus\u00ed znies\u0165 po\u010das zimy agres\u00edvnu priemyseln\u00fa so\u013e, na jar plieskaj\u00face kamienky a v lete prez\u00favanie pneumat\u00edk.<\/p>\n

*Pozn. aj ke\u010f sa farba nan\u00e1\u0161a ako pri striekan\u00ed, st\u00e1le sa jedn\u00e1 o jemn\u00fd pr\u00e1\u0161ok, ktor\u00fd vytvor\u00ed hrub\u00fa vrstvu farby. Aby pr\u00e1\u0161ok dosiahol svoju fin\u00e1lnu odoln\u00fa podobu, mus\u00ed by\u0165 e\u0161te tepelne spracovan\u00fd v peci.<\/p>\n

Pred zabalen\u00edm a odoslan\u00edm s\u00fa disky e\u0161te raz prele\u0161ten\u00e9 a potom sa u\u017e iba bl\u00fdskaj\u00fa na aute.<\/p>\n
