Pagbabawas ng ingay at pagbabawas ng vibration lubricating oil (taba)

Lubricant para sa ingay ng sasakyan at mga problema sa vibration

Kung ikukumpara sa nakaraan, ang mga kotse ngayon ay idinisenyo upang magbigay ng mas maayos na pakiramdam sa pagmamaneho at mas tahimik na kapaligiran sa loob. Dahil dito, mas binibigyang pansin ngayon ng lahat ang mahinang ingay at bahagyang ingay na hindi pa napapansin noon.

Ang ingay, vibration, at acoustic roughness (NVH) at buzzing, squeak, at squeak (BSR) ay maaaring sanhi ng maraming panloob at panlabas na bahagi. Maaaring kabilang sa mga pinagmumulan na ito ang alitan ng goma sa mga coatings, metal sa mga plastik, at sa pagitan ng katad at katad, o mula sa makina.

Norbert ® Ang mga pampadulas na may mataas na pagganap ay mainam para sa paglutas ng NVH at BSR dahil maaari nilang:

  • Madaling ilapat sa pamamagitan ng pag-spray o pagsipilyo
  • Hindi apektado ng malupit na kondisyon tulad ng ulan, niyebe, yelo, asin, alikabok at dumi
  • Fuel resistance, coolant, brake fluid at washing fluid
  • Mababang pagsingaw o walang pagbabago sa katangian sa buong buhay ng kotse
  • Tugma sa lahat ng iba pang mga sangkap at ibabaw na maaaring makontak

Matugunan ang mga inaasahan ng driver at pasahero

Hinimok ng mga pangangailangan ng customer, sinubukan ng mga automaker sa loob ng maraming taon na bawasan ang NVH at BSR gamit ang iba 't ibang mga passive na diskarte sa disenyo at mga aktibong teknikal na katangian.

Ang pagbabawas ng ingay at pagbabawas ng vibration ay mga pangunahing pagsasaalang-alang para sa mga bagong mamimili ng kotse - lalo na sa pagdating ng mga EV (mga de-kuryenteng sasakyan) - at kadalasang nakakaapekto sa pang-unawa ng mga mamimili ng kotse sa kalidad at halaga ng kotse. Bilang karagdagan sa halatang nakakainis, maraming mahahalagang dahilan kung bakit gustong bumili ng mga mamimili ng kotse ng tahimik, maayos na sasakyan.

Kabilang dito ang:

  • Ang mababang dalas at mid-frequency na ingay ay maaaring maging sanhi ng pagkapagod sa pagmamaneho.
  • Maaaring limitahan ng mataas na dalas ng ingay ang kakayahan ng mga tao na makarinig ng mga pag-uusap sa loob ng sasakyan.
  • Ang ingay ay maaaring magdulot ng pananakit ng ulo, stress, at pagkamayamutin.
  • Ang panginginig ng boses ay maaaring magdulot ng pagkamayamutin at kakulangan sa ginhawa

Norbert ® Aling mga okasyon ang angkop para sa mga pampadulas ng kotse?

Norbert ® Ang mga aplikasyon ng mga pampadulas ng PFPE sa mga sasakyan ay karaniwang nahahati sa dalawang kategorya:

sa ilalim ng hood

Dahil ang aerodynamics ay nangangailangan ng mas mahigpit na packaging, at ang mas malalaking makina ay pinapalitan ng mas maliliit na turbocharged at supercharged na mga makina upang mapabuti ang kahusayan ng gasolina, ang temperatura sa ilalim ng hood ay unti-unting tumataas. Dahil ang ambient temperature sa ilalim ng hood ay lumampas sa 120C (248F), ang bilang ng mga automotive application na nangangailangan ng PFPE lubricant ay tumataas din, kabilang ang:

  • Super-speed decoupler para sa alternator drivewheels
  • Front-end accessory transmission (FEAD) tensioner at idler wheel
  • throttle body bearings
  • Exhaust gas recirculation (EGR) valve
  • Intake manifold seal at actuator
  • fan clutch bearings
  • balbula ng kontrol sa paglabas ng sistema ng gasolina
  • Electric cooling system pump at balbula
  • takip ng sistema ng pag-aapoy

Ingay, panginginig ng boses at pagkamagaspang ng tunog sa loob at labas ng kotse (NVH)

Norbert ® Ang mga pampadulas ay isang pangmatagalang solusyon na may mataas na kahusayan na nag-aalis ng humuhuni, langitngit, at dumadagundong na tunog (BSR) sa loob at labas ng sasakyan. Ang mga PFPE lubricating oil at grasa na ito ay maaaring epektibong mabawasan ang ingay na dulot ng friction sa pagitan ng mga ibabaw, pati na rin ang ingay na dulot ng mekanikal na panginginig ng boses, nang hindi nagdudulot ng anumang mga problema sa compatibility ng materyal o gumagawa ng mga nakakapinsalang volatile organic compounds (VOC). Kasama sa ilang aplikasyon ang:

  • Windshield at elastomer seal
  • Panloob na plastic, metal at leather na ibabaw
  • Center console hinges at latches
  • Sistema ng pag-lock ng pinto at puno ng kahoy
  • pagpupulong ng pedal ng preno
  • Pag-install ng upuan (slide rail, headrest iron rod at lock)
  • switch ng kuryente
  • tagsibol ng airbag
  • panlabas na salamin
  • bushing ng suspensyon
