Cov Cheebtsam ntawm Trailer Brake Pads
Dec 09, 2025
Trailer brake pads kuj yuav tsum muaj lub zog siab, tiv thaiv tshav kub thiab ruaj khov kev sib txhuam. Txawm li cas los xij, piv nrog cov tsheb thauj khoom (lub taub hau tsheb laij teb), lawv tuaj yeem them nyiaj ntau dua rau tus nqi, kev hloov pauv ib puag ncig thiab kev sib koom ua ke nrog lub tsheb loj. Cov khoom tseem ceeb muaj xws li:
1. Txhim kho fiber ntau
- Hlau fiber ntau: Qhov kev xaiv tseem ceeb, muab lub zog yooj yim, thermal conductivity thiab hnav tsis kam.
- Mineral fibers (xws li basalt thiab silicate): Txo cov nqi thiab tswj cov coefficient ntawm kev sib txhuam.
- Composite fibers: Ib qho me me ntawm aramid lossis iav fibers yog siv los txhim kho toughness.
2. Adhesive
- Phenolic resin: Feem ntau siv matrix, tab sis nyob rau hauv trailer nres ncoo, hloov resin tej zaum yuav raug saws los txhim kho qis - kub adhesion (tsim rau kev siv sib nrug).
- Roj Hmab hais: Siv rau buffering vibrations thiab txo suab nrov.
3. Kev sib txhuam regulator
- Cov khoom siv hlau: cam khwb cia hlau hmoov, tooj liab hmoov (txhim kho thermal conductivity thiab stability), tab sis ib puag ncig kev cai yuav txwv cov ntsiab lus tooj liab.
- Hnav-cov tshuaj tiv thaiv: alumina, barite (barium sulfate) - Barite tsis tuaj yeem ua kom muaj kev sib txhuam, tab sis kuj txo cov suab nrov, thiab siv dav hauv cov tsheb nres tsheb.
- Lubricating Cheebtsam: Graphite, coke, los tiv thaiv kev puas tsuaj rau lub nruas nres tsheb thaum lub sij hawm siab - kub hnav (feem ntau yog ua los ntawm cam khwb cia hlau).
- Cov ntaub ntawv ceramic: Qee cov qauv siab -kawg ntxiv cov khoom siv ceramic los txhim kho siab -kub durability.
4. Lwm yam additives
- Cov ntaub ntawv txo suab nrov: mica, roj hmab hais, thiab lwm yam, kom txo qis braking whistling.
- Anti- xeb txheej: Cov phaj nraub qaum feem ntau raug kho rau kev tiv thaiv xeb kom haum rau qhov chaw nres tsheb sab nraum zoov.
