Kodi moyo waufupi wa ma brake pads ndi wotani?

Opanga ma brake pad pagalimoto: Kodi moyo waufupi wa ma brake pads ndi uti?

Monga ndi zinthu zonse, mphamvu ya intermolecular ulalo amachepetsa pa kutentha kwambiri. Mfundo ya braking ndi kulola mphamvu ya kinetic kuti isanduke mphamvu ya kutentha ndi kukangana kuti ikwaniritse braking (lingaliro la mphamvu zamagetsi), kotero kutentha kwakukulu komwe kumapangidwa ndi brake pad ndi friction ya disc kudzaunjikana pamwamba pa zinthu za brake pad friction, choyambirira ananyema pad kuti akwaniritse mu nyengo mkulu kutentha, pad ananyema kukhalabe mphamvu zokwanira, M'pofunika kusankha mkulu kutentha zosagwira utomoni, mkulu chiyero graphite, mkulu chiyero barium sulphate ndi zipangizo zina, ndipo zipangizozi ndi monga inu kusankha yekha kukula malasha galimoto ya carbon, mtengo adzauka kwambiri.

Ndipo mapadi otsika kwambiri, sangagwiritse ntchito zinthu zabwino zotere, kotero sangathe kutsimikizira kukhazikika pa kutentha kwakukulu, ndipo ndi kuwonjezeka kwa liwiro, kutentha kumakhala kochuluka, kutentha kumakhala kwakukulu, mphamvu yolumikizira imakhala yochepa, motero kuchepetsa Kuthekera kwa braking, kuwonetseredwa ngati mtunda wa braking ukukulitsidwa. Chifukwa chake, ma brake pads omwe mutha kuyendetsa pa 20 mpaka 60 km / h mumzinda sizitanthauza kuti muli ndi mtunda wokhazikika womwe umathamanga kwambiri. Pamene mphamvu yolumikizira ya unyolo wa mamolekyu imachepetsedwa pakutentha kwambiri, kuvala kwake kumafulumizitsa, chifukwa chake moyo wautumiki wa ma brake pads ambiri umakhala waufupi kwambiri m'mapiri kapena nthawi zambiri amakhala mwadzidzidzi.
