Ngonyaka odlule, ibhasi likagesi elihlanzekile labhekana nokwehluleka okungazelelwe kwe-brake assist engxenyeni eqhubekayo yokwehla kwe-Yunnan-Guizhou Plateau. Uphenyo luthole ukuthi imbangela eyinhloko kwakuwukwehluleka kwesilawuli se-vacuum okubangele ukuthi iphampu ye-vacuum ime, kanti ithangi le-vacuum elincane lalingenawo amandla okugcina, okwacishe kwabangela ingozi enkulu1. Leli cala ladalula izingozi zokuklama zezinhlelo zendabuko ze-vacuum assist futhi lenza imboni yaqala ukuhlola kabusha indima ebalulekile yamaphampu e-vacuum e-micro DC ezinhlelweni ze-electronic assist zezimoto.

Kungani izimoto zikagesi kufanele zithembele kumaphampu amancane okuhlanza umoya?

Ezimotweni zikaphethiloli zendabuko, i-intake manifold yenjini ikhiqiza ngokwemvelo ingcindezi engemihle, ihlinzeka ngomthombo wamahhala we-vacuum ohlelweni lokusiza amabhuleki4. Kodwa-ke, izimoto zikagesi azinawo injini, futhi ngaphandle komthombo we-vacuum, i-brake pedal iba nzima kakhulu - amandla okubhuleka okubhuleka ngesandla kuphela awahlangabezani nezidingo zokuphepha.

Ngalesi sikhathi,iphampu ye-vacuum ye-micro DCu-p uba yisisombululo kuphela:

Ukushayela ngogesi: sebenzisa ngqo ugesi wemoto ongu-12V/24V, shayela i-piston noma i-diaphragm ukuze uhambe ngesivinini esikhulu enjinini, bese ukhipha i-vacuum3 ngenkuthalo;

Impendulo esheshayo:Isibonelo, i-HD-PC3025N ingasungula ingcindezi engemihle engu--70kPa ngaphakathi komzuzwana owodwa ukuze ihlangabezane nezidingo zokubhuleka eziphuthumayo3;

Ukunikezwa kwamandla okuzimele:akukhawulelwe yizimo zokusebenza kwenjini, ingasebenza ngisho noma imoto ingashintshi

Amaphampu amancane okuhlanza umoya anqoba kanjani izithiyo futhi ahlangabezane kanjani nezidingo zezimoto eziqinile?

1. Izinkomba zokusebenza: ibhalansi phakathi kwe-vacuum kanye nokugeleza

Inselele yePlateau:Ekuphakameni kwamamitha angu-3,000, ingcindezi yomoya yehla ifinyelele cishe ku-70kPa (101kPa endaweni ethafeni). Uma i-vacuum ejwayelekile yephampu ingu-50kPa kuphela, ingcindezi yangempela engemihle izobola ibe yi--20kPa, okuholela ekushodeni okukhulu kwe-brake assist. Ngakho-ke, kubalulekile ukukhetha imodeli ene-vacuum engu-≥-70kPa (njenge-PC3025N) ukuze ushiye umkhawulo wokuphepha.

Ukuncipha kokugeleza:Kumpompi ogeleza kancane kancane ongu-25L/min, ukugeleza kwangempela kungase kwehle kufike ku-15L/min ngemva kokuxhuma ipayipi elingamamitha angu-1 + izindololwane ezimbili. Ngesikhathi sokubhuleka okuqhubekayo (njengokwehla okude), uma ukugeleza kunganele futhi ingcindezi yethangi le-vacuum ingakwazi ukugcinwa, i-alamu yebhuleki izoqala ukusebenza.

 

2.Ukuthembeka: Umshuwalense ophindwe kabili wokuqina nokuvimbela ukwehluleka

Ukuhlolwa kokukhuthazela kwamahora angu-1500:I-Ruhaizhibo iEVP Pro yenziwe ngcono ngama-rotor e-graphite, futhi isikhathi sayo sokuphila sidlula esokuncintisana kwamanye amazwe.

Isinyathelo 2: Qondanisa i-vacuum kanye nokugeleza

Ithebula lokuhlola okusheshayo (ukuthatha amamodeli avamile e-Pincheng njengesibonelo)

 

Idizayini ephindaphindayo yesilawuli esiphindwe kabili:Uhlelo olusha lusebenzisa izilawuli ezimbili ze-vacuum ezihambisanayo. Uma eyodwa yehluleka, enye isengalawula iphampu ukuze isebenze, isuse ukwehluleka kwephuzu elilodwa

Isu lokunciphisa umthwalo elihlakaniphile:Uma kutholakala ukuvuza kwe-vacuum (i-gradient yengcindezi engavamile), ishintshela ngokuzenzakalelayo kumodi yokusebenza ngezikhathi ezithile ukuvimbela imoto ukuthi ingashi.

Ukuzivumelanisa nezimo zemvelo: kusukela ekubandeni okukhulu kuya emswakama ophezulu

Ukubekezelela umhwamuko wamanzi:Uhlelo lwamabhuleki lungaphefumula umoya omanzi, futhi amaphampu avamile avame ukugqwala. Kodwa-ke, iphampu encane ye-vacuum ye-PC ivumela ukuthi le medium "icebile ngomhwamuko wamanzi" futhi isebenzisa izivalo ze-fluororubber ngaphakathi.

-30℃ ukuqala okubandayo:amaphampu enjini angenamabhulashi (njenge-VML series) asengasabela ngokushesha emazingeni okushisa aphansi, egwema ingozi yokuqina kwezinhlelo ze-hydraulic zendabuko

 

3. Izinselele Zangempela: Izithiyo Nezixazululo ze-Microi-vacuumamaphampu

Nakuba ubuchwepheshe sebuvuthiwe, amaphampu amancane asabhekene namaphuzu amathathu ayinhloko obuhlungu ekusetshenzisweni kwawo:

Ukusetshenziswa kwamandla kanye nokungqubuzana kwe-NVH (umsindo nokudlidliza)

Amaphampu ageleza kakhulu avame ukuba namandla angaphezu kuka-40W, futhi ukusebenza okuqhubekayo kudla amandla amakhulu (okungaba ngu-0.5% webanga lemoto kagesi). Ngesikhathi esifanayo, umsindo wemoto ungadluliselwa ekhabetheni. Izixazululo:

Injini engenamabhulashi + ukulawulwa kwemvamisa eguquguqukayo: Isibonelo, uchungechunge lwe-VML lunciphisa ukusetshenziswa kwamandla okungasebenzi ngokulawulwa kwesivinini7;

Isembozo esingangeni msindo + ukunciphisa ukudlidliza kwepayipi: ikhambi elivamile lama-OEM.

Ingozi yokushisa ngokweqile ezindaweni eziphakeme kanye nezimo zokuvuza

Ezindaweni eziphakeme noma lapho uphawu luhluleka, ipompo ingashisa kakhulu ngenxa yokusebenza kwesikhathi eside. Isilawuli esisha simisa ipompo ngobuhlakani ngokuqapha i-pressure gradient:

Uma i-gradient yokwehla kwengcindezi ingaphansi kuka-8mbar/s phakathi nemizuzwana eyi-10 yokusebenza, uhlelo lubhekwa njengolujwayelekile futhi iphampu iyamiswa ngokushesha;

Uma i-gradient ingavamile (ukuvuza), izongena emjikelezweni wokuvikela "wokusebenza imizuzwana eyi-15 + ukuma kwemizuzwana eyi-10".

Umdlalo wesikhala nezindleko

Amaphampu amakhulu okugeleza (njenge-PC3025N) anesisindo esingu-1kg futhi athatha isikhala se-chassis. Nakuba isisombululo sethangi le-vacuum eliphindwe kabili kanye nesisombululo sethangi le-vacuum elikhulu sithuthukisa ukuthembeka, izindleko zikhuphuka cishe ngo-30%15. Umkhuba wemboni udizayini ehlanganisiwe: I-Haizhibo ifaka isilawuli emzimbeni wephampu ukuze inciphise ama-wiring harnesses kanye nama-interfaces6.

 

Isiqondiso sesikhathi esizayo: hhayi nje "indima yokusekela"

Ngokuthuthukiswa kokushayela okuhlakaniphile, imisebenzi yamaphampu amancane okuhlanza iyanda:

Isipele esingafuneki sokushayela ngokuzimela ngaphezu kwezinga le-L3:Uma ibhuleki le-hydraulic hydraulic lihluleka, uhlelo lwe-vacuum booster luthatha indawo njengesipele semishini7;

Ukunikezwa komoya omisiwe okusebenzayo:Amanye amamodeli asebenzisa iphampu efanayo ye-vacuum ukuze anikeze amandla isiphethu somoya, okwenza "iphampu eyodwa yokusetshenziswa okuningi"6;

Ukujikeleza kwe-hydrogen emotweni yamaseli kaphethiloli e-hydrogen:Amaphampu amancane amelana nokugqwala asetshenziswa ohlelweni lokujikeleza kwe-hydrogen ukuthuthukisa ukusetshenziswa kukaphethiloli3.

 

Isiphetho: Izingxenye ezibalulekile, kodwa kudingeka ukulungiswa kwezinga lesistimu

Amaphampu e-vacuum e-Micro DC ahlangabezana ngokugcwele nezidingo zosizo lwamandla zezimoto zikagesi zesimanje, kodwa kumele "akhethwe ngokwezimpawu":

Izimoto zomndeni:Izinga le-PC3025N (-70kPa, 25L/min) elinesilawuli esisodwa + ithangi lokuhlanza elingu-8L lanele8;

Izimoto zezentengiselwano/amamodeli asezintabeni: zidinga amaphampu angaphezu kuka--80kPa + izilawuli ezimbili + amathangi amakhulu e-vacuum angu-15L, futhi zilungiselele ukuqapha kwe-pressure gradient14;

Izimoto ezihlakaniphile zesikhathi esizayo:Amaphampu enjini angenamabhulashi (njenge-VML) azoba yinto evamile, kucatshangelwa ukusebenza kahle, ukuthula kanye nokulawula okuhlakaniphile67.

Njengoba onjiniyela bevumelana: Kungakhathaliseki ukuthi ukusebenza kwephampu eyodwa kuqine kangakanani, akukuhle njengokuhlanganiswa kohlelo "lwe-pump-tank-controller-sensor". Lapho ukhetha, akufanele nje ubheke amapharamitha aqanjiwe ephampu, kodwa futhi uqinisekise umthamo wayo womthwalo kanye nendlela yokuphendula amaphutha ohlelweni lonke lwemoto - phela, ama-millisecond phakathi kwamabhuleki anquma umkhawulo wokuphepha wokuphila.

I-Shenzhen Pincheng Motoruneminyaka eminingi yesipiliyoni ku-R&D kanye nokukhiqizwa kwe-amaphampu amancane okuhlanza umoya, futhi iphumelele isitifiketi sezimoto i-IATF 16949, esinganikeza izixazululo ezinhle zokukhiqizwa kwezingxenye zezimoto.
