Ma Brake Pads: Kudziwa zinthu zopangira ndi njira yopangira

Kuti apange ma brake pad apamwamba kwambiri, pali magawo awiri ofunikira: mbale yakumbuyo ndi zinthu zopangira. Popeza zinthu zopangira (friction block) ndi zomwe zimagwirizanitsidwa mwachindunji ndi brake disc, mtundu wake ndi khalidwe lake zimagwira ntchito yofunika kwambiri pakugwira ntchito kwa ma brake. Ndipotu, pali mitundu yambirimbiri ya zinthu zopangira pamsika, ndipo sitingathe kudziwa mtundu wa zinthu zopangira malinga ndi mawonekedwe a ma brake pad. Ndiye kodi timasankha bwanji zinthu zopangira zoyenera kupanga? Choyamba tiyeni tidziwe magulu a zinthu zopangira:

Phukusi la zipangizo zopangira

Zipangizo zopangira zitha kugawidwa m'mitundu inayi:
1. Mtundu wa Asbestos:Zipangizo zoyambirira zogwiritsidwa ntchito pa mabuleki zinathandiza kwambiri pakulimbitsa mphamvu. Chifukwa cha mtengo wake wotsika komanso kukana kutentha kwambiri, zimagwiritsidwa ntchito kwambiri. Komabe, zinthu za asbestos zatsimikiziridwa kuti ndi khansa ndi azachipatala ndipo tsopano zaletsedwa m'maiko ambiri. Misika yambiri simalola kugulitsa mabuleki okhala ndi asbestos, choncho ndi bwino kupewa izi pogula zinthu zopangira.

2. Mtundu wa theka-chitsulo:Kuchokera ku mawonekedwe ake, ili ndi ulusi ndi tinthu tating'onoting'ono tomwe tingasiyanitsidwe mosavuta ndi asbestos ndi NAO. Poyerekeza ndi zipangizo zachikhalidwe za mabuleki, imagwiritsa ntchito makamaka zipangizo zachitsulo kuti iwonjezere mphamvu ya mabuleki. Nthawi yomweyo, kukana kutentha kwambiri komanso kuthekera kotaya kutentha nazonso ndizabwino kuposa zipangizo zachikhalidwe. Komabe, chifukwa cha kuchuluka kwa zitsulo zomwe zili mu mabuleki, makamaka m'malo otentha pang'ono, zimatha kuyambitsa kuwonongeka kwa pamwamba ndi phokoso pakati pa diski ya mabuleki ndi mabuleki chifukwa cha kupanikizika kwambiri kwa mabuleki.

3. Mtundu wachitsulo chotsika:Kuchokera pa maonekedwe ake, ma brake pads achitsulo chochepa amafanana pang'ono ndi ma brake pads achitsulo chochepa, okhala ndi ulusi ndi tinthu tating'onoting'ono. Kusiyana kwake ndikuti mtundu uwu uli ndi chitsulo chochepa kuposa semi metal, zomwe zimathetsa vuto la kuwonongeka kwa ma brake disc ndikuchepetsa phokoso. Komabe, nthawi ya moyo wa ma brake pads ndi yocheperako pang'ono kuposa ya ma brake pads achitsulo chochepa.

4. Mtundu wa ceramic:Ma brake pads a fomula iyi amagwiritsa ntchito mtundu watsopano wa zinthu zadothi zokhala ndi kachulukidwe kochepa, kukana kutentha kwambiri, komanso kukana kutha, zomwe zili ndi ubwino wosakhala ndi phokoso, fumbi losagwa, kukana dzimbiri kwa wheel hub, kukhala ndi nthawi yayitali yogwira ntchito, komanso kuteteza chilengedwe. Pakadali pano, zili ponseponse m'misika ya North America, Europe, ndi Japan. Kutentha kwake kuli bwino kuposa ma brake pads achitsulo, ndipo chinthu chachikulu ndikuti zimawonjezera nthawi yogwira ntchito ya ma brake pads ndipo sizikuipitsidwa. Mtundu uwu wa brake pad uli ndi mpikisano waukulu pamsika m'zaka zaposachedwa, koma mtengo wake udzakhala wokwera kuposa zipangizo zina.

Kodi mungasankhe bwanji zipangizo zopangira?
Mtundu uliwonse wa zinthu zopangira uli ndi zinthu zosiyanasiyana, monga utomoni, ufa wokangana, ulusi wachitsulo, ulusi wa aramid, vermiculite ndi zina zotero. Zinthuzi zidzasakanizidwa molingana ndi momwe zinthuzo zimagwiritsidwira ntchito ndipo tidzalandira zinthu zopangira zomwe tikufuna. Tapereka kale zinthu zinayi zosiyanasiyana m'nkhani yapitayi, koma ndi zinthu ziti zopangira zomwe opanga ayenera kusankha popanga? Ndipotu, opanga ayenera kumvetsetsa bwino msika womwe akufuna kugulitsa asanapange zinthu zambiri. Tiyenera kudziwa kuti ndi zinthu ziti zopangira mabuleki zomwe zimakonda kwambiri pamsika wakomweko, momwe misewu yakomweko ilili, komanso ngati zimayang'ana kwambiri pa vuto la kutentha kapena phokoso. Zinthu zonsezi ziyenera kuganiziridwa.

Gawo la zipangizo zopangira

Ponena za opanga okhwima, nthawi zonse amapanga ma formula atsopano, kuwonjezera zida zatsopano zamakono mu fomula kapena kusintha kuchuluka kwa zinthuzo kuti ma brake pads agwire bwino ntchito. Masiku ano, msika umawonekeranso zinthu zopangidwa ndi kaboni-ceramic zomwe zimagwira ntchito bwino kuposa za ceramic. Opanga ayenera kusankha zinthu zopangira malinga ndi zosowa zenizeni.
