Ungayikhetha kanjani i-jack car

Abantu abaningi bayazi ukuthi ujeke wenzeni. Ngalo, ungakwazi ukuphakamisa umthwalo ngesisindo esibaluleke kakhulu ekuphakameni okuthile. Ngokungafani nezinye izindlela zokuphakamisa, i-jack ihlale ibekwe kusuka ngezansi. Awukwazi ukwenza ngaphandle kwayo uma udinga ukushintsha isondo noma wenze umsebenzi othile ngaphansi komzimba. Idivayisi enjalo kufanele ifakwe ekucushweni kwanoma iyiphi imoto entsha, futhi kufanele igcinwe njalo ku-trunk, ngoba noma yini eyenzekayo emgwaqeni. Kodwa ujeke ungaphuka noma ulahleke.Kuyenzeka ukuthi udinga ikhophi yesibili noma idivayisi ekhona ivele iphazamiseke ukuyisebenzisa. Umbuzo wokukhetha i-jack entsha ungadideka, ikakhulukazi uma ukuthengwa okunjalo kwenziwa okokuqala.

Cishe wonke ama-jack akhona awela ezigabeni ezintathu eziyinhloko - mechanical, hydraulic kanye ne-pneumatic.

Ngokusho komklamo, izinhlobo ezinhlanu ezivame kakhulu zamajack zingahlukaniswa:

1. Isikulufu.
2. I-Rack.
3. Ibhodlela.
4. Ukuginqika.
5. Imicamelo ephefumulayo (ijekhi yomoya yaseSelson).

Izikulufu nama-rack kanye nama-pinion lifts kuyimishini nje, kuyilapho ama-bottle and rolling lifts zisebenzisa ama-hydraulic.

Ezimweni eziningi, amadivaysi asebenza ngesandla - usebenzisa i-lever noma ukuguqula isibambo. Kodwa kukhona amamodeli asebenza ngenjini evuthayo yangaphakathi kagesi.

Kukhona iqoqo lezinhlobonhlobo zama-screw jacks, kodwa okokuqala, lawa amamodeli amise okwedayimane, avame ukuhlonyiswa ngezimoto, ngakho-ke lezo mishini zaziwa kubashayeli abaningi bezimoto.



iqukethe amalever amane kanye nesikulufu esixhuma iziqongo eziseceleni ze-rhombus. Isimiso sokusebenza silula kakhulu - lapho isikulufu sizungeziswa, iziqongo eziseceleni ziyasondelana, futhi phezulu nangaphansi ziyahlukana, ngenxa yokuthi umthwalo obekwe endaweni yesikhulumi engxenyeni engenhla yedivayisi uyaphakanyiswa.

Umthamo wokuthwala ezimweni eziningi awedluli amathani ama-2. Ezimotweni zabagibeli, lokhu kwanele. Ukuphakama okuphezulu kokuphakama kungaphakathi kuka-470 mm, kanti i-pickup encane isuka ku-50 mm.

Ama-jack anjalo athandwa kakhulu phakathi kwabashayeli ngenxa yezinzuzo eziningi:

• isisindo esilula nobukhulu bukuvumela ukuthi uyithwale esiqwini sanoma iyiphi imoto;
• ubulula kanye nekhwalithi yokuklama inquma impilo ende yesevisi (ngaphandle uma, yiqiniso, umkhiqizo usezingeni elihle);
• ukuphakama okuphansi kokuthatha kanye nokuphakama okukhulu ngokwanele kokuphakama okuphezulu kwenza idivayisi enjalo ifanele amamodeli amaningi emoto;
• intengo ephansi.

Ijekhi emise okwedayimane nayo inobubi obanele:

• umthamo womthwalo omncane uma kuqhathaniswa;
• indawo encane yokwesekwa futhi, ngenxa yalokho, hhayi ukuzinza okuhle kakhulu, ngakho-ke kungcono ukufaka umshwalense ngokungeziwe ngomthwalo ophakanyisiwe;
• akuyona indlela elula kakhulu yokuzungezisa isikulufu;
• isidingo sokuhlanza njalo nokugcoba.

Lapho kuthengiswa kukhona namadivayisi alula futhi ahlangene we-lever-screw.



Ama-jack anjalo ashibhile kakhulu, kodwa kungcono ukugwema ukuwathenga, ngoba anezinkinga ezinkulu ngokuzinza, ikakhulukazi ezindaweni ezingalingani. Ukuwa kwemoto ngeke kumenzele okuhle, kodwa into eyinhloko ingozi yokulimala kabi kumuntu.

, eyaziwa nangokuthi i-hijack (i-high-jack) noma i-high-lift (i-high-lift), ihlukaniswa nokuphakama okuphansi kwe-pickup, ukuphakama okukhulu kwe-lift - kufika kumitha eyodwa nesigamu - nokulawula okulula. Ipulatifomu yokuphakamisa itholakala engxenyeni engenhla yesitimela, enezimbobo eziningi ze-latch ngobude bayo bonke. Ukuhambisa ujantshi ngeplatifomu kwenziwa kusetshenziswa i-lever. Izindlela zokwenyuka nokwehla zishintshwa ngokuphenyisisa i-lever yokukhiya.

Kukhona nama-rack kanye nohlobo lwe-pinion jacks. Basebenzisa igiya lezikelemu eline-ratchet, futhi liqhutshwa ukuzungezisa isibambo.



I-Hijack inosayizi omkhulu nesisindo. Amadivayisi anjalo athandwa kakhulu phakathi kwabanikazi be-SUV, kanye nalabo abasebenzisa imishini yezolimo. Ujeke usiza ukukhipha indlela efanayo odakeni. Futhi kubanikazi bezimoto ezijwayelekile, lokhu akuyona into engcono kakhulu.

I-rack kanye ne-pinion jack idinga isisekelo esiqinile. Uma kungenjalo, kuyadingeka ukufaka indawo yesikhulumi esikhethekile, ngaphandle kwalokho isithende sejack sizocwila emhlabathini othambile. Kufanele ifakwe ngokuqinile, futhi ukukhuphuka nokwehla kufanele kwenziwe ngokushelela, kuqinisekiswe ukuthi akukho ukuhlanekezela.

I-rack jack ayisona isitendi esizinzile kakhulu ngoba inonyawo oluncane. Ngakho-ke, umthwalo ophakanyisiwe kufanele uvikeleke, isibonelo, ngelogi noma izitini. Futhi noma kunjalo ungagibeli ngaphansi kwemoto! Kuzo zonke izinhlobo zama-jack, i-rack ne-pinion yiyona ehlukumeza kakhulu.

I-Hijack ayinconywa ukuthi igcotshwe, njengoba ukungcola kunamathela emafutheni, okungabangela umshini wokujamu.

isebenza nge-hydraulic. Iphampu yokushayela idala umfutho kawoyela kusilinda esisebenzayo, esisebenza ku-plunger, ephushela induku phezulu. Induku enesiteji esikhethekile engxenyeni engenhla icindezela umthwalo, iwuphakamise. Ukuba khona kwe-valve kuvimbela amafutha ukuthi angabuyeli emuva. Ukuze uvikele i-jack ekushiyekeni ekwakhiweni, kuvame ukuba ne-valve eyengeziwe yokudlula evulekayo uma umthwalo ovunyelwe weqiwe.

Ngaphezu kwezinduku ezilodwa, kunamamodeli amaningi e-telescopic anamabili, futhi ngezinye izikhathi anezinduku ezintathu ezinwebekayo ukusuka kwenye njengezingxenye ze-antenna ye-telescopic. Lokhu kukuvumela ukuthi ukhuphule ubude bokuphakama obuphezulu bufinyelele cishe ku-400…500 mm. Abanikazi bezimoto ezinemvume ephezulu yomhlabathi kufanele banake, isibonelo, iloli lamathani angu-6.

Ukuphakama kweveni yamadivayisi anjalo kuqala kusuka ku-90 mm (isibonelo, imodeli), futhi umthamo wokulayisha ungafinyelela amathani angama-50 noma ngaphezulu.

Ojeke bebhodlela banezinzuzo eziningi ezibenze basetshenziswa kabanzi. Phakathi kwazo:

• umthamo omkhulu wokuthwala;
• ukusebenza kahle;
• ukunemba kokuyeka ukuphakama;
• ukulungisa okuzenzakalelayo;
• izindleko eziphansi zabasebenzi;
• usayizi omncane nesisindo kukuvumela ukuthi uwuthwale esiqwini.

Ukungalungi okuyinhloko ukuphakama okuncane kokuphakamisa, isivinini esiphansi, ubunzima ngokunciphisa ukuphakama kokunemba.

Ukugcinwa nokuthuthwa kwama-jacks we-hydraulic kufanele kwenziwe kuphela endaweni eqondile ukuvimbela ukuvuza koketshezi olusebenzayo.

kuyasebenza nasezinsizeni zokuphakamisa amanzi. Umgomo wokusebenza kwawo awuhlukile ngokuyisisekelo ebhodleleni. Umthwalo okhokhelwayo uyafana. Ukuphakama kweveni ikakhulukazi 130 ... 140 mm, kodwa ngezinye izikhathi ngaphansi kuka-90 mm. Ukuphakama kokuphakama 300…500 mm.

Zonke izinzuzo zamabhodlela ojeke, ezibalwe ngenhla, zijwayelekile kuma-rolling hydraulic lifts. Ngaphandle kobukhulu nesisindo. Amadivayisi aginqikayo, ngaphandle kokungavamile, makhulu kakhulu futhi asindayo ukuhamba unomphela emotweni yabagibeli.

Izinzuzo ezengeziwe zalolu hlobo lwamajack zihlanganisa ukuzinza okuphezulu, ikhwalithi, ukuphepha kanye nokusebenziseka kalula. I-rolling lift ine-platform enamasondo, ngenxa yokuthi ishayela ngaphansi kwayo ngesikhathi sokuphakamisa umthwalo. Ngesikhathi esifanayo, ngokungafani nazo zonke ezinye izinhlobo zama-jack, ukuchezuka kwedivayisi kusuka mpo akufakiwe.

Kodwa-ke, ukusetshenziswa kwama-jacks okugoqa kudinga indawo esezingeni futhi eqinile engenamatshe nezinye izinto zangaphandle. Zilungele izitolo zamathaya nezindawo zokusebenzela. Egalaji lomuntu siqu, kunengqondo ukuthenga idivayisi enjalo uma ngokuvamile kufanele ushintshe amasondo (ngokwakho, izihlobo, abangane) noma wenze ukulungisa okuthile. Uma ujeke usetshenziswa ngezikhathi ezithile, kungcono ukuthenga ibhodlela elishibhile noma ujeke wedayimane.

Kudingeka futhi ukucabangela ubukhulu begaraji, ibhokisi elincane lingase libe liminyene kakhulu ukuze likhuphuke. Ezimweni ezinjalo, udinga ukukhetha imodeli ngengalo ejikelezayo ukuze isebenze ngokuhambisana nemoto nodonga. Ukunethezeka okwengeziwe kungaba i-foot pedal, esheshisa inqubo yokuphakamisa umthwalo.

empeleni, ingumcamelo ophefumulayo owenziwe ngezinto eziphezulu ze-polymer, ezibekwe ngaphansi komzimba wemoto. I-hose ixhunywe kwipayipi ye-exhaust, futhi amagesi okukhipha umoya agcwalisa igumbi le-jack air, elifaka umoya futhi liphakamise imoto. Ukuba khona kwe-valve yokuhlola akubandakanyi ukuphephetha komcamelo ngokungafanele. Ungakwazi futhi ukugcwalisa igumbi nge-compressor noma isilinda somoya ocindezelweyo. Ukuze unciphise ukucindezela, kune-valve evula ngokucindezela i-lever ekhethekile.

Ukugcwalisa kwenzeka ngokushesha okukhulu, futhi umzamo womzimba awudingeki, ngakho-ke abesifazane bazoyazisa le jack.

I-footprint enkulu ivumela ukusetshenziswa kwe-air jack ukukhipha umshini odakeni, iqhwa noma isihlabathi. Ukuphakama kweveni elincane - mayelana ne-150 mm - kwenza kube nokwenzeka ukusebenzisa idivayisi yezimoto ezinemvume ephansi yomhlabathi.

Amamodeli amaningi ama-jacks we-pneumatic afakwe idivayisi egoqayo enamasondo, okokuqala, akhulisa ukuphakama kwe-pickup, futhi okwesibili, ayilula kakhulu eqhweni noma esihlabathini. Lokhu kufanele kucatshangelwe lapho ukhetha imodeli ethile.

Kuyafaneleka futhi ukunaka ukuba khona kwama-grooves akhethekile endaweni yesikhulumi sokuphakamisa i-jack, okuvimbela umshini ukuthi ungasheleli ngesikhathi uphakamisa noma wehlisa. kufanelekile futhi ukuba nesiteji sensimbi ngaphansi komcamelo kusuka ngezansi, lokhu kuzokwandisa ukuzinza okuphelele kwesakhiwo.

Ukuphila kwenkonzo yejack ye-pneumatic kunqunywa ngokuyinhloko isikhathi sokuguga sempahla yekamelo, ngakho-ke ikhwalithi yayo kufanele inikezwe ukunakwa okukhethekile.

Ukungalungi akubandakanyi ukuzinza okuphezulu kakhulu kanye nobunzima bokugcina ubude obunqunyiwe bokuphakamisa umthwalo, ngoba ngenxa yokucindezela kwegesi, ukucindezela ezingxenyeni ezahlukene zekamelo kungase kuhluke. Kukhona futhi ingozi yokuthi ikhamera izolinyazwa izinto ezicijile ngesikhathi isetshenziswa noma igcinwa.

Kodwa, mhlawumbe, i-drawback eyinhloko yalolu hlobo lwedivayisi intengo ephakeme kakhulu, yingakho abaningi bezokhetha izinketho ezishibhile.

Uma imoto inamapayipi amabili e-exhaust, i-airbag ngeke ifuthe. Kuzodingeka usebenzise ezinye izindlela zokupompa.

Ungakhetha i-jack ngokwemibandela ehlukene, kodwa imingcele emithathu eyinhloko yobuchwepheshe ibalulekile, ehlala ikhonjiswe emzimbeni kanye nokupakishwa kwejekhi. Lawa amandla okuthwala, ubude be-pickup (ihhuku) kanye nokuphakama okuphezulu kokuphakama.

1. Umthamo womthwalo uyisisindo esiphezulu ujeke oklanyelwe ukusiphakamisa ngaphandle kwengozi yokukhubazeka. Ngokuvamile kushiwo ngamathani. Kufanele kukhunjulwe ukuthi isisindo esiphelele semoto ngemuva kokushaywa kwayo sisakazwa phezu kwamasondo amathathu kanye ne-jack. Ukuze ube ne-margin yokuphepha, kungcono ukhethe idivayisi engakwazi ukumelana okungenani nengxenye yesisindo semoto elayishiwe. Umthamo wokulayisha oweqile ngeke uthinte ukusebenza, kodwa intengo ingase ibe phezulu. Akufanele futhi uthathwe ngokonga - amathuluzi anjalo akufanele asetshenziswe ngomkhawulo wamandla awo.
   
   Isisindo sephasiphothi sezimoto asivamile ukudlula ithani nengxenye, amaSUV angaba nesisindo esingu-2 ... 3 amathani.
2. Ubude be-Pickup. Leli yibanga elincane elingaba khona phakathi kwesisekelo esisuka ngezansi kanye nenkundla yokusekela ujeke kusuka phezulu. Le parameter inquma ukuthi kuzokwazi yini ukushelela i-jack ngaphansi kwemoto ethile enemvume ethile. Kulesi simo, kuyadingeka ukucabangela isimo esingenzeka ngesondo eliphukile, lapho imvume yomhlabathi yangempela ingaphansi kwepasipoti. Vumela ngokuphelele umoya uphume ethayini futhi ulinganise imvume ewumphumela - ukuphakama kwejekhi kufanele kulingane nenani elitholiwe. Isitokwe eseqile asisizi ngalutho lapha, njengoba le parameter ihlobene nokuphakama kokuphakama okukhulu okufanele kube ngokwanele ukuze isondo liphume phansi.
   
   Uma unemoto ene-low ground clearance, kufanele unake okuthiwa. amamodeli hook. Zine-pickup ukuphakama kwe-20 ... 40 mm.
3. Ukuphakama okuphezulu kokuphakama yibanga ukusuka endaweni yokugenca lapho imoto ingakhushulwa khona. Kufanele kube ngokwanele ukulenga isondo.
4. Isisindo nobukhulu. Zibalulekile ngomshini ozohlala usemotweni.
5. Amandla adingekayo ukuze asetshenziswe ku-lever noma isibambo sokusebenza. Ngamanye amazwi, uzojuluka kangakanani ukuze uphakamise umthwalo.
6. Ukuba khona kwe-rubber gasket kuyadingeka uma umshini ungenazo izindawo ezikhethekile zokufaka i-lift.

Ngemva kokuthenga ujeke, ungajahi ukuyibeka esiqwini. Kungcono ukuyihlola ngokushesha futhi uqiniseke ukuthi iyasebenziseka, ithembekile futhi ngeke ikulahlekise lapho kuphakama isidingo sokuyisebenzisa okungenzeka.
