Yini i-jack, yenzelwa ini nokuthi ukhetha kanjani

I-jack iyinto okufanele ibe nayo esiqwini sayo yonke imoto. Ngisho neminyaka engama-40 edlule, zonke izimoto zazifakwe ama-jack, lezi kwakuyimishini yokubeka ne-pinion enesisindo somthwalo we-500 kg noma ngaphezulu. Namuhla sinethuba lokukhetha noma iyiphi i-jack enezici ezidingekayo, engasetshenziswa kokubili imoto yakho kanye neziteshi zesevisi.

Yini ujack

Ijack iyithuluzi lokuphakamisa elungisa imoto ekuphakameni okunikeziwe. Ngenxa yokusetshenziswa kwe-lift, kungenzeka ukufeza ukufaka isondo, ukuxilonga nokulungisa ukumiswa ngaphandle komgodi nokuphakamisa. Phakathi kwezinye izinto, i-jack ingasetshenziswa empilweni yansuku zonke lapho udinga ukuphakamisa izinto ezisindayo. Imakethe yezimoto igcwele zonke izinhlobo zamajack, ezihlukile komunye nomunye ngendlela yokwenza, izici nokusebenza.

Inhloso kanye nomgomo wokusebenza kwejekhi

I-jack iklanyelwe ukuphakamisa nokubamba umthwalo ohlezi kuyo, isibonelo, imoto ngesikhathi sokulungiswa (ukushintsha isondo, i-shock absorber, njll) Umgomo wokusebenza uzoxhomeka ohlotsheni lwedivayisi. Isibonelo, imodeli ye-hydraulic isebenzisa ukunyakaza kwenduku ngaphansi kwesenzo sokucindezela okukhulu koketshezi olusebenzayo.

Kungakhathaliseki ukuthi hlobo luni lwe-jack kanye nomthamo wayo wokulayisha, bonke banesimiso esifanayo sokusebenza. Ngakolunye uhlangothi, ujeke uhlezi phansi, kanti ngakolunye uhlangothi, umthwalo uphakanyiswa. Ukuhambisa induku (noma isiteji sokuphakamisa), uhlobo oluhlukile lwe-lever lusetshenziswa. Ukuze wenze umsebenzi othile, kusetshenziswa uhlobo oluthile lwamajack (izici zokuklama zomshini ziyacatshangelwa).

Idivayisi nezici

Ukuze uhlobo ngalunye lukajeke lukwazi ukubhekana nomsebenzi olunikezwe wona, lungase lube nomklamo okhethekile. Idivayisi kajack yakudala iqukethe:
