I VD4, Isaphuli sesekethe esaziwayo se-ABB esiphakathi, sithengise malunga nesigidi seeyunithi kwihlabathi liphela. Nangona ukuthembeka kwayo, iimpazamo zenzeka, ngokukodwa kwindlela yokusebenza. Abasebenzi bezolondolozo baxhomekeke kwimanyuwali ye-ABB, kodwa izikhokelo ezineenkcukacha zinqabile. Ngokucazulula i-VD4 echithiweyo, umbhali ubonelela ngeembono zokunceda kumsebenzi osebenzayo.

Umatshini we-VD4 ubonisa i-spring scroll spring kunye ne-main shaft, kunye ne-multi-stage tripping ukuze kugcinwe indawo kunye nokuguqulwa, ukukhutshwa nge-cam lever.

1.Ugcino lwaMandla:

I-VD4 isebenzisa imithombo yokuskrola ezinzileyo ecwangcisiweyo, iphucula ukusebenza kakuhle komatshini xa kuthelekiswa nemithombo yemveli.

Isiqendu esihleliweyo:

Umzobo 1: I-Plain Scrolling Spring

Njengoko kubonisiwe kwi-Figure 1, enye isiphelo se-spring scroll spring sikhuselekile kwi-shaft enkulu, ngelixa elinye isiphelo lifakwe kwi-spring casing. Ngexesha logcino lwamandla, isiphelo se-shaft esiphambili se-volute spring sihlala simile, kunye ne-motor yokugcina amandla okanye i-rocker yokugcina amandla ijikeleza i-spring casing ngewotshi (njengoko ijongwe kwicala lasekhohlo lomatshini; uqhelaniso olufanayo lusebenza kuyo yonke indawo) nge-ratchet pawl, ityathanga, kunye negiya enkulu, ngaloo ndlela icinezela intwasahlobo yokuskrola.

Xa kufikwa ekuvuleni nasekuvaleni imisebenzi, isiphelo seqokobhe lesiphethu sokuskrola silungisiwe, kwaye ekukhululweni kwesixhobo sokukhubeka, ishaft ephambili ijikeleza ngaxeshanye phantsi kokuqhubela phambili kwentwasahlobo yomqulu, ikhupha amandla ayo agciniweyo.

Ngenxa yokuba i-VD4 isebenzisa i-planar scroll spring, inguqu phakathi kwamazwe asentwasahlobo "engatshajwanga" kunye "nendawo egciniweyo" iyahluka kwiindlela ezininzi ezisebenza entwasahlobo. Ibandakanya i-gap-fixed ilungiselelo kwi-shell spring shell, iququzelelwe ngokulungelelaniswa kwediski, ikhamera encedisayo efakwe kwi-shaft engundoqo, kunye ne-roller efakwe kwintonga yokudibanisa yokugcina amandla. Ngendlela elula, xa ukugcinwa kwamandla kugqityiwe, i-roller, eqhutywe yintonga yokudibanisa yokugcina amandla, idibanisa kwi-notch kwidiski. Ngenxa yoko, intonga yokudibanisa ugcino lwamandla ijikeleza kwi-angle ethile, ikhuthaza ugcino oluncedisayo logcino lwamandla kunye nesalathiso somatshini wogcino lwamandla ukutshintshela kwimo ye "Energy Stored". Ngakolunye uhlangothi, ngexesha lenkqubo yokuvala i-circuit breaker, i-radius ephezulu ye-cam encedisayo idlula i-gap ye-disk, iqhube i-roller ibuyele kumda wangaphandle we-disk. Esi senzo siqhuba intonga yokudibanisa yokugcina amandla ibuyele kwi-engile yayo yoqobo, ibangela ugcino oluncedisayo logcino lwamandla kunye nesalathiso somatshini wogcino lwamandla ukubuyela kwimeko ye "Non-Energy Stored".

2. Imodyuli yohambo

Imodyuli yohambo yeVD4 switch switch yesixhobo iqhayisa ngoyilo olucekethekileyo nolwahlukileyo. Ngaphandle kokuntsonkotha kwayo okubonakalayo, ekuyichitheni nasekuyihlalutyeni, yonke imodyuli yokunqunqa inokwahlulwa ibe ziziseko ezithathu ezisisiseko zokukhwela:

Ulwakhiwo lwenqanaba lokuqala lubandakanya i-roller yangaphambili kunye nediski yebhuleki yepleyiti enkulu enemilo yefeni, esebenza njengesixhobo sokukhubeka esikhethekileyo se-"detent + roller". Inqanaba lesibini libandakanya ipleyiti enkulu emile okwefeni kunye nehafu-shaft enkulu, eyenza "ihalf-shaft + ipleyiti emile okwefeni" yokukhubeka. Inqanaba lesithathu libandakanya i-half-shaft yokuvula, ipleyiti yokuvula eyi-fan-shaft, i-half-shaft yokuvala, kunye nepleyiti yokuvala efana ne-fan, edibanisa iiseti ezimbini ze-"half-shaft + fan-shaped plate" indibaniselwano yokudibanisa i-clamp.

Umzobo 3: Isazobe seSakhiwo seModyuli yohambo

Imodyuli yohambo ye-VD4 yokutshintsha indlela yokusebenza isebenza zombini ukubamba kunye nomsebenzi wokuhamba. Makhe sihlolisise le misebenzi ngokweenkcukacha.

Ukubamba uMsebenzi:

Ukuthatha indawo yokuvala njengomzekelo, xa isenzo sokuvala sigqityiwe, i-roller yangaphambili yepleyiti enkulu efana ne-fan iwela kwi-slot ehambelanayo kwi-disc ye-brake. Ngeli xesha, i-half-shaft enkulu ibanjwe ngokukhuselekileyo kwisakhiwo se-pincer esakhiwe ngamacwecwe ecandelo lokuvula kunye nokuvala. Oku kuthintela ii-roller zangaphambili zeeplate zecandelo elikhulu ukuba ziphakanyiswe, zivale ngokufanelekileyo i-disc ye-brake kunye nokugcina i-shaft ephambili kwindawo yokuvala.

Tripping Function:

Ngoku, makhe siqwalasele umsebenzi wokukhubeka sisebenzisa isenzo sokuvula njengomzekelo. Xa isixhobo sifumana umyalelo wokuvula, isiqingatha se-axis sokuvula sijikeleza ngasekunene nge-engile ethile. Le ntshukumo ibangela ukuba ipleyiti yefeni yokuvula ilahlekelwe yifulcrum yayo yethutyana kwaye ijikelezise ngaxeshanye, ichitha ulwakhiwo lwenkxaso olumilise okwepincer eyenziwe kukuvula nokuvala iipleyiti ezimilise okwefeni. Ngenxa yoko, i-half-axis enkulu ijikeleza i-counterclockwise phantsi kwesenzo sokubuya kwentwasahlobo, ikhulula ipleyiti enkulu efana nefeni. Ipleyiti enkulu emile okwefeni emva koko iphakamisa irola yangaphambili phantsi kwentshukumo yentwasahlobo ebuyayo, ikhulule idiski yebhuleki. I-disc ye-brake ijikeleza i-clockwise phantsi kwesenzo somqulu we-spring spring, iqalisa isenzo sokuvula.

Ngethuba lenkqubo yokuvula, intonga yokudibanisa kwi-shaft encedisayo yokuvula kunye nokuvala isikhundla (njengoko kuboniswe kuMzobo 4) iqhubela iplate yecandelo lokuvula ukuze iphinde iphinde iphinde iphinde iphinde iphinde iphinde ivule i-half-shaft. Oku kuphinda kumisele ulwakhiwo lwenkxaso olumilise okwe-clamp eyenziwe ngamacwecwe ecandelo lokuvula kunye nokuvala kwaye ityhala i-half-shaft enkulu ibuyele kwi-engile yayo yokuqala. Kwangaxeshanye, iidiski ezincedisayo kumacala omabini e-brake disc zisebenza kwiirola ezingasemva zepleyiti emile okwefeni njengoko zijikeleza neshaft engundoqo. Oku kuphakamisa indawo engasemva yepleyiti enkulu emile okwefeni kwaye yehlise indawo engaphambili, ilungiselela ukutshixa okulandelayo kwerola yangaphambili kwidiski yebhuleki.

Umzobo 4: Isikhundla sokuvula kunye nokuvala i-Shaft eNcedisayo yokuQhagamshela intonga

3. IModyuli Yeziphumo

Imodyuli yokuphuma kwendlela yokusebenza ye-VD4 yinto ebalulekileyo eguqula ukunyakaza okujikelezayo kwe-shaft engundoqo kwi-linear motion efunekayo ukuvula nokuvala i-breaker circuit. Iqukethe iidiski ezintathu zekhamera ezifakwe kwi-shaft engundoqo kunye namakhonkco amathathu ahamba ngengalo ephindwe kabini abekwe ezantsi kwendlela.

Ikhonkco elihamba kabini-ingalo elihambayo lisebenza njenge-lever, kunye ne-fulcrum yayo ephakathi. Isiphelo sangaphambili se-lever siphenjelelwa yi-cam disc kwi-shaft engundoqo, ngelixa isiphelo sangasemva sidibaniswe ne-insulating pull rod ye-bubble vacuum kunye ne-spring yokuvula.

Ngethuba lokusebenza lokuvala, i-disc ye-cam ijikeleza kunye ne-shaft ephambili, icinezela phantsi kwii-rollers ekupheleni kwekhonkco elihamba ngengalo ephindwe kabini. Esi senzo siphakamisa isiphelo esingasemva sekhonkco, sityhalela intonga yokutsala isigqumathelo phezulu kwaye ivale abafowunelwa abaguqukayo nabamileyo ngaphakathi kweqamza levacuum. Ngaxeshanye, intwasahlobo yokuvula ixinzelelwe, igcina amandla omsebenzi wokuvula olandelayo.

Ngokwahlukileyo, ngexesha lokuvula, i-disc ye-cam ijikeleza kwicala elichaseneyo, ikhulula i-roller ekupheleni kwangaphambili kwekhonkco elihamba ngengalo ephindwe kabini. Oku kuvumela intwasahlobo yokuvula ukwandisa, ukwahlula abafowunelwa abaguqukayo kunye ne-static kunye nokuvula isiphaluka.
