Dab tsi yog cov teeb meem tshwm sim ntawm cov pawm nres?

Lub coefficient ntawm kev sib txhuam cuam tshuam li cas braking?

Nres pads nrog xws li qis lossis siab coefficient ntawm kev sib txhuam yuav cuam tshuam lub tsheb kev ua haujlwm ntawm lub tsheb. Tshwj xeeb tshaj yog thaum lub tsheb xav tau thaum muaj xwm ceev braking thaum tsav tsheb ntawm txoj kev loj, kev sib txhuam coefficient siab heev uas cov brakes yuav tsis ntse, thiab kev sib txhuam coefficient tsawg heev uas cov log tsheb yuav kaw, uas yuav ua rau lub tsheb flick thiab tshuab. tawm. Kev nyab xeeb tsav tsheb yog ib qho kev hem thawj loj. Raws li lub teb chaws tus qauv, qhov haum ua hauj lwm kub ntawm kev sib txhuam phaj yog 100-350degree. Txawm li cas los xij, thaum qhov kub ntawm ntau qhov kev sib txhuam tsis zoo ntawm daim hlau nce mus txog 250degreeC, kev sib txhuam coefficient yuav poob qis, yog li cov brakes yuav ua tsis tiav rau lub sijhawm no. Feem ntau hais lus, raws li tus qauv SAE, cov tuam txhab kev sib txhuam phaj yuav siv FF rating coefficient, uas yog, kev sib txhuam coefficient yog {{0}}.35 ~ 0.45.

Dab tsi yog qhov kev sib raug zoo ntawm lub neej ntawm kev sib txhuam phaj thiab hardness?

The life of the friction plate has no certain relationship with the surface hardness. However, if the surface hardness is high, the actual contact area between the friction plate and the brake disc is large, which often affects the service life. Therefore, the main factors affecting the life of the friction plate include hardness, strength, and abrasiveness of the friction material. Under normal circumstances, the service life of the front friction plate is 30,000 km, and the service life of the rear friction plate is 120,000 km.

Vim li cas qhov kev vibration tshwm sim thaum braking?

Nws yog feem ntau tshwm sim los ntawm deformation ntawm cov kev sib txhuam hauv ob sab phlu los yog lub nres disc, uas yog txuam nrog rau cov khoom, ua kom raug thiab cua sov deformation ntawm kev sib txhuam hauv ob sab phlu thiab lub nres disc. Cov laj thawj tseem ceeb yog vim li cas lub thickness ntawm lub brake disc tsis zoo li qub, lub nruas nres Tsawg dua roundness, tsis zoo li kev puas tsuaj ntawm cov phaj txhuam, thermal deformation thiab kub kub, thiab lwm yam. Tsis tas li ntawd, lub deformation los yog tsis tsim nyog installation ntawm lub nres calipers. , thiab qhov tsis sib xws ntawm kev sib txhuam coefficient ntawm kev sib txhuam phaj kuj yuav ua rau kev vibration thaum braking. Tsis tas li ntawd, yog tias qhov kev vibration zaus tshwm sim los ntawm kev sib txhuam phaj thaum lub sij hawm braking thiab ncua kev kawm ntawv resonate, nws kuj yuav ua rau jitter.
