Pad brake pad
Pele ho lilemo tsa bo-1970, li-brake pads li ne li e-na le palo e kholo ea lisebelisoa tsa asbestos, li nka mocheso o phahameng oa mocheso, ho hanyetsa mollo, le litšoaneleho tsa ho ferekana, empa hobane phofo e hlahisoang ke asbestos tlhahiso le tšebeliso, ho na le mefuta e sa tšoaneng ea tšenyo 'meleng oa motho. , e leng bonolo ho baka mekhoa ea ho hema.Mafu a bile a na le kankere, kahoo mariki a k'hothone hajoale a thibetsoe ke lefats'e.
Joale, li-brake pads tsa hona joale li bitsoa NAO brake pads (Non-Asbestos Organic, non-free organic brake pads), eo ka kakaretso e nang le 10% -30% ea lisebelisoa tsa tšepe, hape e kenyelletsa likhoele tsa semela, Fibers ea khalase, carbon, rabara, khalase le lisebelisoa tse ling.
Li-brake pads tsa organic li ntlafalitse ts'ebetso ea taolo ea moaparo le lerata ka lilemo tse ngata tsa nts'etsopele le ntlafatso ea thepa, empa hape li loketse ho khanna letsatsi le letsatsi.Lerōle le hlahisoang le tšenyo ea "brake disc" e fokotsehile.Leha ho le joalo, ka lebaka la litšenyehelo tsa thepa, joalo-joalo, filimi ea "organic brake" hangata e theko e boima, 'me fektheri ea pele e tla sebelisoa ka kakaretso ho mefuta e bohareng le e phahameng.
Semi-metal brake pad
Seo ho thoeng ke halofo ea tšepe ke haholo-holo linthong tse ferekaneng tse sebelisoang ho li-brake pads, ho tloha hoo e ka bang 30% -65% ea tšepe - ho akarelletsa le koporo, tšepe, joalo-joalo. theko e batlang e le tlase, 'me bofokoli bo bakoa ke mabaka a lintho tse bonahalang, lerata nakong ea mariki le tla ba le leholo,' me ho roala ha lisebelisoa tsa tšepe ho disk ea brake ho tla ba khōlō.Kaha semi-metal brake pad e na le litšobotsi tsa rona ka holimo, ho na le likopo tse peli tse kholo, e 'ngoe ke fektheri ea pele e tšehetsang li-brake pads tsa mefuta e bohareng le e tlaase - mofuta ona ke theko e tlaase.Tsela e 'ngoe e haholo-holo tšimong ea letlalo la brake le fetotsoeng - hobane li-brake tsa tšepe li ntle, li loketse haholoanyane likoloi tse sebetsang hantle kapa liketsahalong tse sa tšoaneng.Ntle le moo, ka mokhoa ona oa ts'ebeliso, mocheso o phahameng oa letlalo la brake o tla fihla ho feta likhato tse 800 tsa Celsius.Kahoo re ka bona hore lihlahisoa tse ngata tse fetotsoeng li na le lisebelisoa tse phahameng tsa tšepe bakeng sa mariki a ho khanna ka bohale le liketsahalo.
