Jack ndi chiyani, ndi chiyani komanso momwe mungasankhire

Jack ndiyofunika kukhala nayo mu thunthu la galimoto iliyonse. Ngakhale zaka 40 zapitazo, galimoto iliyonse inali ndi jacks, izi zinali rack ndi pinion zipangizo ndi mphamvu katundu wa makilogalamu 500 kapena kuposa. Lero tili ndi mwayi wosankha jack iliyonse yokhala ndi mawonekedwe ofunikira, omwe angagwiritsidwe ntchito pagalimoto yanu komanso malo ochitira chithandizo.

Jack ndi chiyani

Jack ndi chida chokweza chomwe chimakonza galimotoyo kutalika kwake. Ndiyamika ntchito Nyamulani, n'zotheka kuchita matayala koyenera, diagnostics ndi kukonza kuyimitsidwa popanda dzenje ndi kukweza. Mwazina, jack itha kugwiritsidwa ntchito m'moyo watsiku ndi tsiku pomwe zinthu zolemetsa zimayenera kukwezedwa. Msika wamagalimoto umadzaza ndi mitundu yonse ya ma jacks, omwe amasiyana wina ndi mzake mwa mawonekedwe, machitidwe ndi magwiridwe antchito.

Cholinga ndi mfundo ya ntchito ya jack

Jackyo imapangidwa kuti ikweze ndikugwira katundu wokhazikika pa iyo, mwachitsanzo, galimoto panthawi yokonza (kulowetsa gudumu, chowombera chogwedeza, etc.) Mfundo yogwiritsira ntchito idzadalira mtundu wa chipangizo. Mwachitsanzo, chitsanzo cha hydraulic chimagwiritsa ntchito kusuntha kwa ndodo pansi pa kupanikizika kwakukulu kwa madzi ogwira ntchito.

Mosasamala mtundu wa jack ndi mphamvu yake yolemetsa, onse ali ndi mfundo yofanana yogwirira ntchito. Kumbali imodzi, jack amakhala pansi, ndipo mbali inayo, pa katundu akunyamulidwa. Kusuntha ndodo (kapena nsanja yonyamulira), lever yamtundu wina imagwiritsidwa ntchito. Kuti agwire ntchito inayake, mtundu wina wa jacks umagwiritsidwa ntchito (mapangidwe a makina amaganiziridwa).

Chipangizo ndi makhalidwe

Kuti mtundu uliwonse wa jack ukhale wokhoza kuthana ndi ntchito yomwe wapatsidwa, ukhoza kukhala ndi mapangidwe apadera. Chida cha jack classic chili ndi:
