Cov Ntaus Nres thiab Cov Npe Nruab Nrab Los Sib Poob
Nres tshuab tsis hloov pauv tag nrho hauv lub xyoo pua dhau los, tab sis kev tsim kho lub zog tshiab sawv cev hloov hiav txwv nyob rau hauv txoj kev uas peb xav txog braking. Cov kev kho tau zoo tshaj qhov qub tshaj qhov uas tsis yog lub hauv siab, xws li kev hloov ntawm lub nruas brakes rau disk nres. Nws tseem muaj kev txhawb zog rau hauv cov ntaub ntawv ntawm lub cev uas ua los ntawm cov cuab yeej ua los ntawm, uas tau ua rau cov khoom tsis sib haum xeeb ntev ntev dua, tsim cov hmoov av tsawg, thiab tsis tshua hnov suab. Cov txheej txheem zoo li cov xauv txheej txheem tiv thaiv kuj ua rau kev siv technology zoo dua, tab sis lub hauv paus pib ntawm kev hloov cov twj paj nruas hluav taws xob kom tshav kub tsis tau pauv.
Tsoos brakes ua haujlwm zoo, tab sis lawv zoo kawg li. Txhua zaus koj nias rau ntawm koj tus brake pedal, koj yuav raug clamping rau ntawm koj lub log nrog lub zog ntawm ntau phaus phaus hydraulic. Lub cuab tam muaj txoj hlua tig, zoo ib yam li cov nplais ntawm cov log thiab lub log hub, muab cov nplaum los ntawm cov organic, hlau, los yog cov xim tso zis. Nyob rau hauv cov tsheb qub, siv cov nruag tsawg thiab cov khau nres siv tsawg dua. Nyob rau hauv ob qho tib si, lub tsheb txo qeeb vim yog kev sib txhuam ntawm kev sib txhuam uas tau tsim los ntawm cov pawm thiab cov discs los yog khau thiab cov nruas. Qhov kev sib txhuam ntawd tseem yuav hloov lub zog ua kom muaj zog (thiab qee zaus kuj muaj suab nrov nrov), thiab koj lub tsheb yuav qeeb sai li qhov tshwm sim.
Qhov teeb meem nrog cov brakes tsoos yog tias koj lub cav yuav tsum tau siv ntau roj los ua tau lub zog ntawm lub zog, thiab nws yeej tseem khwv tau thaum koj tus brake tso nws mus rau hauv tshav kub. Lub tswv yim tseem ceeb tom qab kev tsim rov qab txhuam braking yog tias ntau lub tshuab ua rau nws ua tau kom rov ua tau qee feem ntawm qhov hluav taws xob, hloov mus rau hauv hluav taws xob, thiab rov qab siv dua.
Yuav ua li cas Regenerative Brakes Ua Haujlwm?
Cov hom kev siv technology uas muaj zog tshaj plaws yog siv lub tshuab fais fab ua ib lub tshuab hluav taws xob, uas yog vim li cas thiaj rov qab ua dua tshiab hauv cov tsheb thiab cov tsheb fais fab. Thaum lub sijhawm ua haujlwm, lub tshuab fais fab siv fais fab los ntawm lub roj teeb thiab siv nws txav lub tsheb. Thaum tus brake pedal yog kev nyuaj siab, lub tshuab hluav taws xob hluav taws xob muaj peev xwm rov qab ua txoj haujlwm no thiab xa hluav taws xob rov qab rau hauv lub roj teeb. Qhov ntawd yuav pab ua kom lub roj teeb uas tsis tas them rau hauv kev siv fais fab lossis siv lub alternator nyob rau hauv ib tug hybrid, uas ua rau kom nce kev ua haujlwm.
Txij li thaum cov neeg txhim kho kom rov qab zoo ua rau lub zog hluav taws xob ua hluav taws xob, lawv muaj peev xwm qeeb ib lub tsheb. Txawm li cas los xij, muaj cov kev txwv rau kev ua haujlwm ntawm lub nruab zog regenerative. Ib qho ntawm cov teeb meem tseem ceeb yog tias cov kev cai nres tsheb tsis ua hauj lwm zoo li ntawm qis qis thaum lawv ua siab loj. Vim tias qhov kev txwv tsis pub muaj nyob rau hauv kev txhim kho kev lag luam, feem ntau cov tsheb kuj muaj kev pabcuam nrog cov tshuaj txuas ntxiv.
Cov kev txwv ntawm Regenerative Brakes
Ntxiv nrog rau lub caij nplooj ntoos zeeg-tawm ntawm regenerative braking efficiency ntawm qis qis, cov tshuab kuj raug mob los ntawm ib tug xov tooj ntawm lwm cov kev txwv. Qee qhov tseem ceeb tshaj yog:
- Tsuas siv cov khoom siv rau sab nraud xwb "tsav lub log."
- Cov cuab yeej kev sib tw tsis zoo siv tsis muaj zog txaus thooj sab hauv kev ntshai nres.
- Kev ua haujlwm ntawm ib qho kev tsim kho tshiab tsuas yog siv los ntawm qhov tseem ceeb xws li lub peev xwm ntawm lub zog cia thiab qhov tsim hluav taws xob.
- Traditional regenerative systems yog incompatible nrog non-hluav taws xob, non-hybrid tsheb.
- Qee lub tshuab rov ua haujlwm raug yuam kom siv cov lus qhia ntxiv "dynamic braking" uas tsis khaws cia cov hluav taws xob lub zog rov qab.
Capacitive Brakes thiab Traditional Combustion Xyaw
Txij thaum regenerative nres tshuab feem ntau cia siab rau lawv cov hluav taws xob hluav taws xob los tsim hluav taws xob, lawv yog cov tsis txuam nrog cov tsheb uas siv sab hauv combustion tshuab. Txawm li cas los xij, muaj qee qhov kev hloov tshiab uas siv tau los siv rau cov kev sib txuas nrog cov combustion tshuab. Ib qho zoo li no siv cov loj capacitors kom ceev ceev thiab tso tawm hluav taws xob, uas yog dhau ntawd dhau los ntawm qhov kev hloov tshuab hluav taws xob. 12-volt tso zis mam li muab tso rau hauv lub qhov hluav taws xob system ntawm lub tsheb, uas yuav siv qee cov khoom tawm ntawm lub cav. Cov tshuab no tam sim no muaj peev xwm nce roj efficiency nce txog li 10 feem pua, tab sis nws yog tseem nyob hauv nws cov me nyuam mos.
Dab Tsi Tsheb Siv Regenerative Brakes?
Feem ntau cov tsheb ciav hlau thiab hluav taws xob siv qee yam ntawm cov cuab yeej kev tsim rov qab. OEMs zoo li Chevrolet, Honda, Nissa, Toyota, thiab Tesla muaj tag nrho cov onboard thaum ntxov nrog regenerative braking technology nyob rau hauv lawv cov hybrid thiab hluav taws xob. Non-hybrid tsheb uas siv qee hom kev tsim rov qab kev lag luam yog muaj tsawg dua, tab sis BMW thiab Mazda tau ob qho tib si adopters ntawm kev siv tshuab hauv qee yam qauv.
