Ma brake pads amatchedwanso ma brake pads. Mu dongosolo la ma brake la galimoto, brake pad ndiye gawo lofunika kwambiri la chitetezo, ndipo brake pad imagwira ntchito yofunika kwambiri pa ubwino wa ma brake onse, kotero akuti brake pad yabwino imateteza anthu ndi magalimoto.
Ma brake pads nthawi zambiri amapangidwa ndi mbale zachitsulo, zigawo zotetezera zomatira ndi zotchingira zomatira. Ma brake pads amakutidwa kuti apewe dzimbiri. Pa nthawi yophimba, SMT-4 furnace temperature tracker imagwiritsidwa ntchito kuzindikira kutentha komwe kumagawidwa panthawi yophimba kuti zitsimikizire kuti ndi yabwino. Gawo lotetezera kutentha limapangidwa ndi zinthu zomwe sizimasamutsa kutentha, ndipo cholinga chake ndi kutetezera kutentha. Gawo lotetezera kutentha limapangidwa ndi zipangizo zomatira ndi zomatira. Mukatseka, limakanizidwa pa disc ya brake kapena brake drum kuti lipange kukangana, kuti akwaniritse cholinga chochepetsa mphamvu ya galimoto ndikuyimitsa. Chifukwa cha kukangana, ma friction pads amatha pang'onopang'ono. Kawirikawiri, mtengo wotsika wa ma brake pads, ndi momwe amavalira mwachangu.
Ma brake pads a magalimoto amagawidwa m'mitundu: - ma brake pads a ma disc brakes - nsapato za brake za ma drum brakes - mpaka ma pad a magalimoto akuluakulu
Ma brake pads amagawidwa m'magulu otsatirawa: ma brake pads achitsulo ndi ma brake pads a carbon ceramic, omwe ma brake pads achitsulo amagawidwanso kukhala ma brake pads achitsulo chochepa ndi ma brake pads a theka-metal, ma brake pads a ceramic amagawidwa ngati chitsulo chochepa, ndipo ma brake pads a carbon ceramic amagwiritsidwa ntchito ndi ma brake disc a carbon ceramic.
Mfundo yoyendetsera mabuleki
Mfundo yogwirira ntchito ya brake makamaka imachokera ku kukangana. Kukangana pakati pa brake pad ndi brake disc (ng'oma) ndi tayala ndi pansi kumagwiritsidwa ntchito kusintha mphamvu ya kinetic ya galimoto kukhala mphamvu yotentha pambuyo pa kukangana ndikuyimitsa galimoto. Dongosolo labwino komanso lothandiza la brake liyenera kukhala lotha kupereka mphamvu yokhazikika, yokwanira komanso yowongolera ya brake, komanso kukhala ndi mphamvu zabwino zotumizira ma hydraulic ndi kutentha kuti zitsimikizire kuti mphamvu yomwe dalaivala amagwiritsa ntchito kuchokera ku brake pedal ikhoza kutumizidwa mokwanira komanso moyenera ku master cylinder ndi sub-pump iliyonse, ndikupewa kulephera kwa hydraulic ndi kuchepa kwa ma brake chifukwa cha kutentha kwambiri.
Moyo wautumiki
Kusintha mabuleki kumadalira nthawi yomwe ma shim anu akhala akugwira ntchito m'galimoto yanu. Nthawi zambiri, ngati muli ndi mtunda woposa makilomita 80,000, mabuleki ayenera kusinthidwa. Komabe, ngati mukumva phokoso lochokera m'mawilo anu, mosasamala kanthu za mtunda womwe mwayenda, muyenera kusintha mabuleki anu. Ngati simukudziwa kuti mwayendetsa makilomita angati, mutha kupita kusitolo yomwe imasinthira mabuleki kwaulere, kugula mabuleki kuchokera kwa iwo kapena kupita ku malo ogulitsira magalimoto kuti akayikidwe.
