Ungakhetha kanjani i-jack yemoto? Ividiyo neziyalezo ezinezici ezibalulekile
Asikho isidingo sokukhuluma ngokuthi ithuluzi ujeke liwusizo futhi lidingeka kangakanani. Wonke umuntu kudingeke ukuthi ashintshe isondo elibhobokile okungenani kanye emgwaqeni, futhi ngaphandle kwejekhi yakho, ubungeke ukwazi ukubhekana nokuphuka.
Ngokuvamile le mishini ifakwe ifektri, kodwa ngokuvamile abashayeli abanelisekile futhi kunesifiso sokuthenga entsha. Yilapho izinkinga ziqala khona, ngoba izitolo zezingxenye zezimoto zinokukhethwa okubanzi.
I-portal yezimoto i-Vodi.su izozama ukubhekana nalesi sihloko.
Izici zamajack
Izinhlaka ezibalulekile:
- umthamo wokulayisha;
- ukuphakama kokuphakamisa;
- ukuphakama kweveni;
- uhlobo lokushayela - mechanics, hydraulics, pneumatics.
Umthamo wokuthwala
Ezimotweni, ama-cross-class-class, ama-minivans, umthamo wokuthwala amathani angu-1-1,5 anele. Akumele uphakamise imoto yonke, vele uphakamise uhlangothi olulodwa kancane ukuze ukhiphe isondo.
Izimoto ezingekho emgwaqeni zidinga imishini enamandla kakhulu, ngoba ngezinye izikhathi kufanele uphakamise ngaphambili noma ngemuva kwemoto ukuze uyikhiphe emgwaqeni. Uma ukhetha amaloli, bese ucabangela umthamo wabo wokuthwala, isibonelo, i-KAMAZ ngokwayo inesisindo samathani angu-5-6, futhi ingathwala amathani angu-15 wempahla. Ngakho, thenga idivayisi eyenzelwe amathani ayi-10-15.
Ukuphakamisa ukuphakama
Ngokuvamile kuba ngamasentimitha angu-30-50, okwanele endaweni eyisicaba. Eziteshini zesevisi, kusetshenziswa ojeke abanobude besiqu eside. Futhi, kuzodingeka ubude obukhulu kuma-SUV abhajwe odakeni.
ukuphakama kweveni
Ngamagama alula, lokhu ukuphakama kwejekhi. Okusho ukuthi, yithathe ukuze ingene ngaphansi kwemoto. Uma imvume iphakeme, futhi ama-stiffeners aphezulu ngaphezu komhlaba, khona-ke idivayisi kufanele ifinyelele kubo kalula.
thayipha drive - le pharamitha idinga ukucatshangelwa okuningiliziwe, ngakho-ke sizonikela ngesigaba esihlukile kuyo.
Izinhlobo zamajeke
Imishini
Okulula kakhulu - nge-mechanical drive. Ngokuvamile, idivayisi yohlobo lwesikulufa ifakiwe ephaketheni, futhi ama-rack-and-pinion afanele ama-SUV. Zombili zithembekile impela.
Izinzuzo zama-screw Jacks:
- thatha indawo encane;
- uzinze kakhulu;
- kukhona indawo ebanzi ukuze kugcizelelwe ukuqina kwemoto.
Kodwa ukususa kwabo ukuthi kufanele wenze imizamo emikhulu yokusiphakamisa - udinga ukuzungezisa isikulufu ngosizo lwesibambo esisebenza njenge-lever.
I-Rack, noma njengoba bebizwa nangokuthi - High Jack Lift:
- ukuphakama okuphezulu - kufika kumitha noma ngaphezulu;
- ingakwazi ukwenza imisebenzi eminingi eyengeziwe - i-winch, i-lift, idivaysi yokwenza ubuhlalu besondo;
- ukuzinza, ukwethembeka.
Yiqiniso, futhi, kufanele wenze umzamo wokuphakamisa, phansi kwemoto kufanele kube namapulatifomu akhethekile okufaka i-tong hook. Kodwa-ke, i-High Jack Lift ifunwa kakhulu abathandi be-off-road.
Kukhona ezinye izinhlobo zamajekhi emishini: uhlobo lwesikere noma ukugoqa. Ezakamuva zinhle ngoba awudingi ukukhathazeka ngokuthi imoto izoshelela noma ujeke uzogingqika.
Ama-Hydraulics
IHydraulic nayo inenani elanele lezinhlobonhlobo. Ukuhlanganiswa kwabo okuyinhloko ukuthi awudingi ukwenza imizamo yokuphakamisa, vele ufake i-lever bese upompa isilinda se-hydraulic, induku izophakamisa umthwalo ngaphandle kokubamba iqhaza kwamandla akho emisipha.
Okuvame kakhulu ojeke bamabhodlela. Zingaba yinduku eyodwa, noma induku emibili, ngenxa yokuthi ukuphakama kokuphakamisa kukhuphuke kakhulu.
Izinzuzo zabo eziyinhloko:
- inkundla yokusekela ebanzi, ithuba elincane lokuketula;
- umthamo ophakeme wokuthwala - kusuka ton eyodwa kuya ku-50;
- ukwethembeka - i-jack yakhelwe ukuze ikwazi ukuphakamisa isisindo esibalwe kanye namaphesenti angu-25, kodwa uma umthwalo unzima nakakhulu, induku izoyeka ukuphakama;
- idizayini elula futhi ehlangene, ithatha indawo encane;
- isisindo esincane.
Ngokuhlangenwe nakho kwethu, singasho ukuthi i-1-2 ton jack yanele ngisho nama-sedans ekilasi D noma E. Kulula kakhulu ukusebenza nawo, noma kunjalo, ngokusetshenziswa njalo, isilinda se-hydraulic angeke simelane, bese kuba uwoyela. iqala ukugeleza. Kulokhu, kufanele wengeze njalo amafutha we-hydraulic ngaphakathi. Zithengeka ngokwezindleko.
Ama-jack hydraulic jacks azibonakalise kahle. Ziyifreyimu emasondweni ehamba ngaphansi kwemoto. I-plus enkulu ukuthi i-cylinder ye-hydraulic itholakala ngokuqondile, futhi uma uqala ukudala ingcindezi ngaphakathi kwe-cylinder nge-lever noma i-pedal, iphakama nge-angle, bese induku iqala ukunwebeka.
Izimfanelo ezinhle zihlanganisa: ukusebenza kahle okuphezulu, ukusebenza kahle, umthamo wokulayisha. Amadivayisi aginqikayo avame ukusetshenziswa eziteshini zesevisi, ngakho-ke azophakamisa kokubili i-hatchback ye-A-class kanye neloli elisindayo elithwala uhlaka.
Kukhona futhi izinhlobo lapho ukucindezela kudalwe khona kusetshenziswa i-motor kagesi exhunyiwe.
I-pneumo-hydraulic, i-pneumatic
Ama-pneumo-hydraulics asebenza ngesimiso esifanayo ne-twin-tube gas shock absorbers, okungukuthi, kukhona ikamelo likawoyela kanye negumbi lomjovo womoya. I-pneumatic amasilinda avuthwe ngumoya.
Abuye abonakale eziteshini zosizo. Inzuzo ebaluleke kakhulu ukuthi baphonswa nge-compressor noma amagesi avela ku-muffler. Kukhona futhi nezinkinga: udinga ukuthwala i-compressor nama-hoses afakwe nawe, athatha isikhala esiningi lapho ehlanjululwa, igumbi lingabhobozwa ngephutha.
Umphumela. Njengoba ubona, kuningi ongakhetha kukho. Uma ungavamile ukusebenzisa ujeke, khona-ke isikulufa esivamile noma uhlobo lwebhodlela le-hydraulic luzokwanela. Ezimotweni ezisindayo, ukukhetha okuhle ngama-hydraulics anamandla okuphakamisa amathani amahlanu noma ngaphezulu.
Iyalayisha...
