Idrayivu yokuhlola i-Ruf ER Model A: Ezokuthutha ngogesi

Isazi esidumile saseBavaria sokuguqulwa nokuhumusha kwePorsche, u-Alois Ruf, sisebenza ngejubane elisheshayo ukudala imoto yezemidlalo kagesi yokuqala yaseJalimane, i-ER.

I-Ruf yaziwa kakhulu kubathandi bezimoto ngokuguqulwa kwayo kwe-supersport ngokusekelwe kumamodeli we-Porsche, kodwa bambalwa abantu abazi ukuthi umsunguli wayo nomsebenzi wokuzilibazisa womnikazi yizitshalo zamandla. I-Alois Ruf isivele inezitshalo ezintathu ezisebenza ngamanzi kagesi ezifakwe kugridi yamandla kagesi waseJalimane, futhi manje uzama ukuhlanganisa ibhizinisi nenjabulo. Ingane yenyunyana yokuzilibazisa nomsebenzi ibizwa nge-ER Model A futhi inawo wonke amathuba okuba imoto yezemidlalo kagesi yokuqala esebenzayo isebenzisa isiteji sobuchwepheshe sePorsche 911.

Ukuzilibazisa okungajwayelekile

“Umbono wethu wokuqala bekuwukuthola ukuthi angakanani amandla anele avela kumabhethri angaphakathi ukuze anikeze isitayela sokushayela esinemidlalo kanye nebanga elifanele,” kuchaza uRufus njengoba ehlose le phrojekthi, wengeza ngokuthi: Amakhasimende ase-US.” .

Isidingo sezinyathelo eziqinile kule ndlela sabonakala, futhi ochwepheshe baseCalmotors - igatsha laseCalifornia le-Ruf Development - bagoqa imikhono yabo. Esikhundleni senjini yesibhakela ehlakaziwe kanye nethangi likaphethiloli le-911 evamile, onjiniyela baseMelika bafaka injini kagesi ehambisanayo, efana nesigubhu somshini wokuwasha ozenzakalelayo ngesimo nosayizi futhi inesisindo esingamakhilogremu angama-90. Injini inamandla e-AC, ayiwasebenzisi amabhulashi futhi ikhulisa amandla afinyelela ku-150 kW (204 hp). Lolu hlobo lwamayunithi kazibuthe unomphela lusebenza kahle kakhulu (90%) kunamamodeli asetshenziswa kakhulu asynchronous.

Esikhundleni setangi

Amabhethri e-lithium-ion asatshalaliswa kuyo yonke imoto. Inani labo eliphelele lingaphezu kuka-96, uxhumano luyi-serial, isisindo siyingxenye yethani. Ukunikezwa kwamandla okuhlaba umxhwele kuklanywe inkampani yaseShayina i-Axeon futhi inohlelo lwe-elekthronikhi lokulawula nokuphatha ugesi kuseli ngalinye ngenethiwekhi yedatha enesivinini esikhulu. I-voltage yokusebenza yenethiwekhi kagesi engaphakathi yi-317 V, umthamo webhethri ngu-51 kWh. Yiqiniso, i-ER ingasebenzisa amandla amaningi ngesikhathi se-inertia kanye ne-braking.

I-Porsche 911 yasekuqaleni eyi-clutch transmission edonsa ngamagiya ayisithupha igcine indawo yayo ku-ER drivetrain, kodwa leyo bhola engadingekile izosuswa maduze. Njengoba ama-motor kagesi enikeza i-torque ephezulu (kufika ku-650 Nm uma uqala), imoto yezemidlalo kagesi ayidingi noma yimaphi amagiya noma i-clutch friction - ukudlulisa okulula nokuphumelelayo kwanele.

Ufudumele

Yiqiniso, izici zobuchwepheshe ze-prototype azikhawulelwe kulokhu. Injini kagesi ye-UQM esetshenziswe kuze kube manje emkhakheni wezimoto ezilula zokuhweba inesivinini esiphansi kakhulu esingu-5000 rpm emshinini kagesi futhi inokupholisa uketshezi olusebenzayo. Ngakolunye uhlangothi, amaphakethe ebhethri awanalo uhlelo olunjalo - iqiniso elimangazayo ngokumelene nesizinda sezinkinga ezaziwa kakhulu zamaseli e-lithium-ion, ukubusa okushisayo okungapheli okuvame ukuholela ekunciphiseni kwempilo yesevisi ngisho naphakathi kwabo. ukwehluleka ngaphambi kwesikhathi.

Nokho, kusobala ukuthi uRufus akamkhathazi ngalokhu. "Sinesipiliyoni sokusebenzisa i-ER ekushiseni kwangaphandle kwamadigri angu-38, futhi siyaqiniseka ukuthi isistimu yebhethri elawulwa nge-elekthronikhi ingaxazulula le nkinga," kusho u-Alois Rufus ngokuzethemba.

Kuthiwani ngombuthano?

Ngesikhathi esifanayo, inhloko yenkampani igcizelela ngokuqondile ukuthi okwamanje imoto kagesi iyisibonelo kuphela. Isinyathelo esilandelayo sokuziphendukela kwemvelo ekuthuthukisweni kwayo kuzoba ukufakwa kwenjini kagesi enesivinini esikhulu eklanyelwe ngokukhethekile i-ER drivetrain kanye nesistimu yebhethri ethuthukisiwe enesisindo esincane kakhulu. Njengamanje, imodeli yezemidlalo emnyama enamandla amakhulu inesisindo esingamakhilogremu angu-1910, okuyinto, ngokusho kwabadali bayo, okungenani amakhilogremu angu-300 ngaphezu kwalokho okufunayo. Kodwa-ke, i-ER isivele isikwazi ukusheshisa ukusuka ku-0 iye ku-100 km/h ngemizuzwana engaphansi kweyisikhombisa, ijubane layo eliphezulu lifinyelela ku-225 km/h, futhi ngesitayela sokushayela esilinganiselwe, ibanga elifinyelela ku-300 km lingenzeka ngebhethri elilodwa. khokhisa. Idatha ngokungangabazeki iyamangalisa futhi ayikhiphi ukuqhathanisa okuqondile ne-Tesla Roadster esivele isilungele ukukhiqizwa ngobuningi. Ngesikhathi esifanayo, u-Alois Ruf akakwazi ukuziqhayisa ngamandla anjalo okutshala izimali ngemuva kwakhe, futhi kwathatha unyaka kuphela ukuletha i-Ruf ER Model A esimweni sayo samanje.

Eqinisweni, uhlobo oluthokozelayo luyathandeka ukuphatha, ngisho nangendlela engeyinhle futhi engaphelele. Umsindo we-powertrain kagesi ukude nemoto yezemidlalo futhi njengamanje uyinhlanganisela engazwakali yokubhuza okungajwayelekile, ukuhayiza nokushaya amakhwela. Kodwa-ke, ukucindezela i-accelerator pedal kuholela ekusheshiseni kombani okusheshayo nokushesha okujwayelekile kwama-motors kagesi, okungangabazeki ukuthi kuzovusa ilukuluku nokulangazelela okuthile kokuthe xaxa kumakhasimende amaningi angahle abe khona. Izinkinga zokukhuluphala nokusatshalaliswa ziphazamise nokuziphatha okunamandla kwe-911, okudala enye inkinga iqembu laseRufa elizodinga ukuyilungisa ngaphambi kokuthi i-ER yokuqala enomkhawulo ifike emakethe ngasekupheleni konyaka ozayo.
