Kev Ntsuam Xyuas Kev Ua Haujlwm ntawm Brake Friction Phaj
Tam sim no, feem ntau ntawm cov phaj txhuam txhuam ntawm kev ua lag luam yog ua los ntawm cov khoom siv sib txhuam semi-metallic thib ob lossis asbestos. Piv nrog Citroen lub thib peb tiam txhim kho high-metal brake pads, nws txawv los ntawm lwm cov tuam txhab uas muag cov tsoos semi-hlau nres pads, uas yog hloov los ntawm ib tug organic formula thiab ib tug me me ntawm tshav kub conduction thiab ua phem thiab tsis zoo nres nres. Ua los ntawm tooj liab lossis hlau, nws daws qhov teeb meem ntawm lub suab nrov thiab kev pab cuam lub neej; Yog li ntawd, lub cim thib peb ntawm ceramic nres pads overthrows ib txwm lub tswv yim ntawm ceramic brakes. Ceramic brake pads yog hloov los ntawm ceramic fibers thiab fillers uas tsis muaj hlau. Cov khoom, cov nplaum thiab cov hlau me me, suav nrog cov ntxhia fibers, aramid fibers thiab ceramic fibers, yog ntau thiab ntau faded dua li lwm cov brakes, thiab cov ntsiab lus ntawm cov nqi qis dua. Ceramic brake pads yog ntau thiab ntau tsis muaj menyuam thiab nyob ntsiag to, thiab Thaum tau txais kev ua haujlwm zoo heev, nws yuav tsis hnav cov khoom ua ke.
Hais txog kev ua tau zoo, cov phaj sib txhuam muaj 4 qhov yuav tsum tau ua:
1 Tsim nyog coefficient ntawm kev sib txhuam
Kev sib txhuam coefficient yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv sib txhuam, uas pom zoo nrog qhov yooj yim braking torque ntawm brakes. Lub teb chaws tus qauv nruj me ntsis kom cov chaw tsim khoom los qhia cov coefficient ntawm kev sib txhuam ntawm pob. Cov coefficient ntawm kev sib txhuam yuav tsum tsim nyog, yog tias nws siab dhau lawm, nws yuav ua rau lub log kaw thaum lub sijhawm braking, kev taw qhia yuav tsoo thiab hlawv lub disc, thiab yog tias nws siab dhau lawm, qhov kev ncua deb ntawm lub braking yuav luv heev. .
2 Trusted kev ruaj ntseg
Nres pads yuav ua rau kub kub tsis tu ncua thaum nres, tshwj xeeb tshaj yog thaum tsav tsheb ntawm txoj kev loj lossis thaum muaj xwm txheej ceev. Nyob rau hauv qhov kub thiab txias, qhov sib txhuam coefficient ntawm kev sib txhuam phaj yuav nce, uas yog hu ua thermal recession. Cov theem ntawm thermal decay pom zoo nrog lub xeev kub thiab kev nyab xeeb thaum muaj xwm ceev braking.
3 Kev nyuaj siab
Kev nplij siab yog ib qho kev qhia tsis ncaj ntawm kev sib txhuam, nrog rau kev xav nres, suab nrov, plua plav, hluav taws, thiab tsw. Nrog rau kev nce ntawm cov tsheb ntiag tug thiab kev txhim kho ntawm tib neeg txoj kev ua neej nyob, raws li qhov yooj yim ntawm kev nyab xeeb, kev nplij siab tau dhau los ua ib qho tseem ceeb ntawm kev sib txhuam daim hlau. Ntawm cov ntsuas kev nplij siab, cov tswv tsheb feem ntau them nyiaj ntau tshaj plaws rau lub suab nrov ntawm cov pawm nres. Nyob rau hauv qhov tseeb, suab nrov yog qhov teeb meem insurmountable tshaj plaws rau tag nrho cov kev sib txhuam khoom manufacturers. Lub suab nrov ua rau muaj kev sib txhuam tsis zoo ntawm cov phaj txhuam thiab cov txhuam txhuam. Qhov laj thawj yog qhov nyuaj heev. Nres quab yuam, nres disc kub, tsheb ceev thiab huab cua tej zaum yuav ua rau lub suab nrov.
Tsis tas li ntawd, yog vim li cas rau lub suab nrov nyob rau hauv peb theem sib txawv ntawm braking pib, braking execution thiab braking tso tawm txawv. Yog tias lub suab nrov nyob nruab nrab ntawm 0 thiab 500Hz, nws yuav tsis hnov hauv lub tsheb, tab sis yog tias nws tsawg dua 1500Hz, tus tswv lub tsheb tuaj yeem hnov cov suab nrov nres.
4 Tsim nyog lub neej ncua
Kev pabcuam lub neej yog cov khoom lag luam ntsuas uas txhua tus neeg tau txais txiaj ntsig zoo rau. Feem ntau, cov nres nres tuaj yeem ua kom muaj kev pab cuam lub neej ntawm 30, 000 mais. Cov khoom me me ntawm graphite thiab tooj dag siv hauv Bosch nres cov ntaub ntawv tseem tuaj yeem ua rau kom hnav ntawm lub nres nres.
Txhawm rau ua kom tau raws li qhov xav tau ntawm cov neeg siv sib txawv, cov khoom lag luam nres nres kuj muaj ntau yam. Piv txwv li, Bosch tau txais ob lub me me ntawm "kev nyab xeeb" thiab "nyiam" cov khoom kom tau raws li cov neeg siv khoom sib txawv. Ntawm lawv, Bosch "kev nyab xeeb" series tau ua tiav cov nqi zoo dua thaum ua tau raws li cov lus pom zoo ntawm kev nyab xeeb thiab kev nplij siab ntawm feem ntau ntawm cov tswv tsheb.
