Chery Original High Quality Car Brake Pads Auto Spare Parts

Ma brake pads agalimoto nthawi zambiri amakhala ndi mbale yachitsulo, zomatira zotchingira kutentha ndi chipika cha mikangano. Chitsulocho chiyenera kupentidwa kuti chiteteze dzimbiri. The SMT-4 ng'anjo kutentha tracker ntchito kudziwa kugawa kutentha kwa ndondomeko zokutira kuonetsetsa khalidwe.

Automobile brake pad, yomwe imadziwikanso kuti automobile brake skin, imatanthawuza kugunda kwa zinthu zomwe zimakhazikika pa ng'oma ya brake kapena brake disc yozungulira ndi gudumu. Mphepete mwa mikangano ndi pad friction imanyamula kukakamiza kwakunja kuti ipangitse kukangana, kuti akwaniritse cholinga chotsitsa galimoto.
Thermal insulation layer imapangidwa ndi zinthu zosatengera kutentha zomwe zimatenthetsera kutentha. Chotchinga chamkangano chimapangidwa ndi zinthu zokangana komanso zomatira. Pochita mabuleki, imafinyidwa pa brake disc kapena drum ya brake kuti ipangitse kugundana, kuti akwaniritse cholinga chotsitsa galimoto ndi mabuleki. Chifukwa cha kukangana, friction block imavalidwa pang'onopang'ono. Nthawi zambiri, ma brake pad okhala ndi mtengo wotsika amavala mwachangu. Pambuyo pogwiritsira ntchito zida zowonongeka, ma brake pads adzasinthidwa nthawi yake, mwinamwake mbale yachitsulo idzalumikizana mwachindunji ndi diski ya brake, yomwe pamapeto pake idzataya mphamvu yowonongeka ndikuwononga diski ya brake.
Mfundo yogwirira ntchito ya braking makamaka imachokera ku kukangana. Kukangana kwapakati pa ma brake pads ndi ma brake discs (ng'oma) ndi pakati pa matayala ndi pansi kumagwiritsidwa ntchito kutembenuza mphamvu ya kinetic yagalimoto kukhala mphamvu ya kutentha pambuyo pa kukangana ndikuyimitsa galimoto. Makina oyendetsa bwino komanso oyendetsa bwino ayenera kupereka mphamvu yokhazikika, yokwanira komanso yowongoka, komanso kukhala ndi ma hydraulic transmission and heat dissipation capacity, kuti awonetsetse kuti mphamvu yomwe dalaivala amagwiritsira ntchito pa brake pedal ikhoza kukhala mokwanira komanso imafalitsidwa bwino ku master silinda ndi sub cylinder iliyonse, ndikupewa kulephera kwa hydraulic ndi kutsika kwachuma chifukwa cha kutentha kwakukulu. Dongosolo la ma brake pagalimoto limagawidwa kukhala ma brake a disc ndi drum brake, koma kuphatikiza pa mtengo wamtengo wapatali, mphamvu ya drum brake ndi yocheperako kuposa ya disc brake.
kukangana
"Friction" imatanthawuza kukana kuyenda pakati pa zinthu ziwiri zomwe zikuyenda. Kukula kwa mikangano (f) imagwirizana ndi kugunda kwamphamvu (μ) Ndipo chopangidwa ndi vertical positive pressure (n) pa friction force bearing surface, yomwe imafotokozedwa motere: F= μ N. Kwa ma braking system: （ μ) Amatanthawuza kugundana kwapakati pa brake pad ndi brake disc, ndipo N ndi mphamvu yoyendetsedwa ndi brake caliper. pisitoni pa brake pad. Kuthamanga kwakukulu kwachitsulo, kumapangitsanso kugwedezeka kwakukulu, koma kugunda kwapakati pakati pa brake pad ndi disc kudzasintha chifukwa cha kutentha kwakukulu komwe kumapangidwa pambuyo pa kumenyana, ndiko kuti, kugunda kwachitsulo (μ) Kumasintha ndi kusintha kwa kutentha. Pad iliyonse ya brake imakhala ndi ma curve coefficient kusintha kokhota chifukwa cha zida zosiyanasiyana. Chifukwa chake, ma brake pads osiyanasiyana azikhala ndi kutentha koyenera kogwira ntchito komanso kutentha komwe kumagwiritsidwa ntchito, zomwe tiyenera kudziwa tikamagula ma brake pads.
Kutumiza kwa braking force
Mphamvu ya brake caliper piston pa brake pad imatchedwa: brake pedal force. Mphamvu ya dalaivala ikadutsa pa brake pedal imakulitsidwa ndi chowongolera cha makina opondaponda, mphamvuyo imakulitsidwa pogwiritsa ntchito mfundo ya kusiyana kwa vacuum pressure kudzera pa vacuum power boost kukankha silinda ya brake master. Kuthamanga kwa hydraulic komwe kumapangidwa ndi silinda ya brake master kumagwiritsa ntchito mphamvu yosasunthika yamadzimadzi kuti iperekedwe ku silinda yaying'ono iliyonse kudzera papaipi yamafuta a brake, ndipo imagwiritsa ntchito "Pascal mfundo" kukulitsa kupanikizika ndikukankhira pisitoni ya silinda yaying'ono. kugwiritsa ntchito mphamvu pa brake pad. Lamulo la Pascal limatanthauza kuti kuthamanga kwamadzimadzi kumakhala kofanana pa malo aliwonse mu chidebe chotsekedwa.
