[vc_row][vc_column][vc_single_image image=”326″ img_size=”full” alignment=”center”][vc_column_text]\u00cen momentul fr\u00e2n\u0103rii, apar \u00eentotdeauna vibra\u021bii datorate fric\u021biunii uscate, care sunt descrise de \u0219ofer prin \u201esc\u00e2r\u021b\u00e2it\u201d,\u201eb\u00e2z\u00e2it\u201d, \u201ezgomot\u201d la fr\u00e2nare, \u00een func\u021bie de frecven\u021ba vibra\u021biei. Aceste zgomote creeaz\u0103 un disconfort puternic conduc\u0103torului auto \u0219i o stare de nesiguran\u021b\u0103 \u00een \u0219ofat.<\/strong><\/p>\n

Cercet\u0103rile \u00eendelungate \u00een laboratoarele produc\u0103torilor au condus la eliminarea acestor vibra\u021bii folosind diverse tehnologii de fabrica\u021bie a pl\u0103cu\u021belor de fr\u00e2n\u0103 \u0219i discurilor de fr\u00e2n\u0103, precum \u0219i ad\u0103ugarea unor elemente auxiliare sistemului de fr\u00e2nare care elimin\u0103 definitiv aceste vibra\u021bii.<\/p>\n

\u00cen compozi\u021bia pl\u0103cu\u021belor de fr\u00e2n\u0103 se utilizeaz\u0103:<\/p>\n

Sulfat de barium, Carbonat de calciu, Mica, Vermiculita, Metale alcaline, Molibden, Cauciuc, Grafit, Oxizi metalici, Siliciu.<\/p>\n

\u00cen cazul pl\u0103cu\u021belor de fr\u00e2n\u0103, ca \u0219i \u00een cazul altor materiale, trebuie g\u0103sit \u00eentotdeauna un compromis \u00eentre siguran\u021b\u0103, confort \u0219i eficien\u021b\u0103 economic\u0103, aceasta fiind ordinea \u0219i niciodat\u0103 invers.<\/p>\n

\u00cen func\u021bie de compozi\u021bia materialului utilizat \u00een fabricarea pl\u0103cu\u021belor de fr\u00e2n\u0103, \u00eent\u00e2lnim urm\u0103toarele mari categorii ale acestora:<\/p>\n

    \n
  1. Azbest (nu se mai produc pentru industria auto)<\/li>\n
  2. Semi metalice (30%-60 % metal) \u2013 durabilitate mare, zgomot crescut<\/li>\n
  3. Organice (fibre \u0219i procent sc\u0103zut de neferoase) \u2013 durabilitate medie, fr\u00e2nare bun\u0103 la temperaturi joase, zgomot redus<\/li>\n
  4. Carbon \u2013 \u00eenalt\u0103 performan\u021b\u0103, foarte scumpe<\/li>\n<\/ol>\n

    Din cauza factorilor mecanici de influen\u021b\u0103 \u0219i a condi\u021biilor de func\u021bionare, suprimarea complet\u0103 a zgomotului la fr\u00e2nare este extrem de dificil\u0103, dar prin intermediul tehnologiei moderne, poate fi ob\u021binut un nivel superior de suprimare.<\/p>\n

    Prin urmare, zgomotul la fr\u00e2nare apare datorit\u0103 urm\u0103torilor factori:<\/p>\n

      \n
    1. Utilizarea unor pl\u0103cu\u021be de fr\u00e2n\u0103 \u0219i discuri de fr\u00e2n\u0103 necorespunz\u0103toare, fabricate \u0219i comercializate \u021bin\u00e2nd cont de factorul economic \u0219i apoi de siguran\u021b\u0103 \u0219i confort. Aceste pl\u0103cu\u021be ieftine sunt produse de produc\u0103tori consacra\u021bi \u00een domeniul pieselor de schimb. Desprinderea materialului de fric\u021biune, ruperea longitudinal\u0103 a materialului, stabilitatea inadecvat\u0103 a materialului de fric\u021biune ca rezultat al deficien\u021bei de presare sunt doar o parte din problemele care apar la produsele de slab\u0103 calitate.<\/li>\n
    2. Montaj incorect al service-ului, f\u0103r\u0103 a acorda aten\u021bie detaliilor care sunt esen\u021biale \u00een func\u021bionarea corect\u0103 a unui sistem de fr\u00e2nare: toleran\u021ba de a\u0219ezare a pl\u0103cu\u021belor de fr\u00e2n\u0103 \u00een etrier, culisele etrierului necur\u0103\u021bate \u2013 blocate, canalul de fr\u00e2n\u0103 necur\u0103\u021bat de murd\u0103rie \u0219i coroziune, piston deplasat \u00een carcasa etrierului, discuri de fr\u00e2n\u0103 a\u0219ezate necorespunz\u0103tor pe suprafa\u021b\u0103 butucului, f\u0103r\u0103 cur\u0103\u021bare prealabil\u0103 a acestuia.<\/li>\n
    3. Montarea unor pl\u0103cu\u021be de fr\u00e2n\u0103 f\u0103r\u0103 a schimba discurile de fr\u00e2n\u0103 uzate peste media admis\u0103. Riscurile de siguran\u021b\u0103, pierderea confortului \u0219i reducerea duratei de via\u021b\u0103 pot fi evitate prin \u00eentre\u021binerea corect\u0103 acordat\u0103 de un tehnician specializat \u0219i utilizarea unor piese componente de calitate.<\/li>\n<\/ol>\n
