Nthawi zambiri, kugundana kwa ma brake pads wamba kumakhala pafupifupi 0.3 mpaka 0.4, pomwe kugundana kwa ma brake pads ochita bwino kwambiri kumakhala pafupifupi 0.4 mpaka 0.5.Ndi kugunda kwamphamvu kokwanira, mutha kupanga mphamvu zambiri zama braking ndi mphamvu yocheperako, ndikukwaniritsa bwino mabuleki.Koma ngati friction coefficient ndi yokwera kwambiri, imayima mwadzidzidzi popanda kutsika mukaponda mabuleki, zomwenso sizili bwino.
Chifukwa chake chofunikira ndichakuti zimatenga nthawi yayitali bwanji kuti mufike pamtengo wokwanira wa brake pad mutatha kuyika mabuleki poyambira.Mwachitsanzo, ma brake pads omwe sagwira bwino ntchito ndizovuta kuti akwaniritse mabuleki ngakhale ataponda mabuleki, omwe nthawi zambiri amatchedwa kusachita bwino kwamabuleki.Chachiwiri ndi chakuti ntchito ya brake pad sikukhudzidwa ndi kutentha.Izinso ndizofunikira kwambiri.Nthawi zambiri, kutentha kotsika komanso kutentha kwambiri kwamphamvu kwambiri kumakhala ndi chizolowezi chochepetsa.Mwachitsanzo, coefficient of friction amachepetsa pamene mpikisano galimoto kufika wapamwamba kutentha, amene ali ndi zotsatira zoipa.Mwa kuyankhula kwina, posankha ma brake pads kuti azitha kuthamanga, ndikofunikira kuyang'ana momwe zimagwirira ntchito pamatenthedwe apamwamba komanso kuti mukhalebe ndi braking performance kuyambira koyambira mpaka kumapeto kwa mpikisano.Mfundo yachitatu ndi kuthekera kosunga bata pakachitika kusintha kwa liwiro.
Ma brake pad friction coefficient ndiwokwera kwambiri kapena otsika kwambiri akhudza momwe mabuleki amagwirira ntchito.Mwachitsanzo, pamene galimoto ikuthamanga kwambiri, friction coefficient imakhala yochepa kwambiri ndipo mabuleki sangakhale ovuta;kugundana ndi kokwera kwambiri ndipo matayala amamatira, zomwe zimapangitsa kuti galimotoyo idutse ndikudumpha.Zomwe zili pamwambazi zidzasokoneza kwambiri chitetezo cha galimoto.Malinga ndi mfundo za dziko, yoyenera ntchito kutentha zofunda ananyema mkangano kwa 100 ~ 350 ℃.Kusauka kwabwino kwa brake friction pads kutentha kumafika 250 ℃, kugundana kwake kumatsika kwambiri, pamene mabuleki adzakhala opanda dongosolo.Malinga ndi muyezo wa SAE, opanga ma brake friction pad amasankha FF level rating coefficient, ndiye kuti, friction rating coefficient of 0.35-0.45.
Nthawi zambiri, mawonekedwe aukadaulo a ma brake pads amayikidwa pafupifupi 300 ° C mpaka 350 ° C kuti ayambitse kuchepa kwa kutentha;pomwe ma brake pads apamwamba amakhala pa 400 ° C mpaka 700 ° C.Kuphatikiza apo, kutsika kwa kutentha kwa ma brake pads pamagalimoto othamanga kumayikidwa mokwera momwe kungathekere kusungitsa kokwana kocheperako ngakhale kutentha kutayamba.Nthawi zambiri, kutentha kwamphamvu kwapadiboli wamba ndi 40% mpaka 50%;kutentha kwapang'onopang'ono kwa ma brake pads omwe amagwira ntchito kwambiri ndi 60% mpaka 80%, zomwe zikutanthauza kuti kugundana kwa ma brake pads wamba kusanachitike kutentha kumatha kusungidwa ngakhale kutentha kwatsika.Opanga ma brake pad akhala akugwira ntchito yofufuza ndi kukonza kapangidwe ka utomoni, zomwe zili mkati mwake, ndi zida zina za ulusi kuti apititse patsogolo kutentha kwa kutentha komanso kuchepa kwa kutentha.
Santa Brake waika ndalama zambiri pa kafukufuku ndi chitukuko cha ma brake pad formulations kwa zaka zambiri, ndipo tsopano wapanga dongosolo lathunthu la semi-metallic, ceramic, ndi low-metallic, lomwe lingagwirizane ndi zosowa zosiyanasiyana zosiyana. makasitomala ndi madera osiyanasiyana.Timakulandirani kuti mufunse za katundu wathu kapena kukaona fakitale yathu.
