Kodi kusankha jack galimoto? Kanema ndi malangizo okhala ndi zofunikira
Palibe chifukwa chofotokozera momwe jack ilili yothandiza komanso yofunikira. Aliyense asintha tayala loboola kamodzi panjira, ndipo popanda jeki yanu, simungathe kupirira kuwonongeka.
Kawirikawiri makinawa ali ndi fakitale, koma nthawi zambiri madalaivala sakhutira ndipo pali chikhumbo chogula chatsopano. Apa ndipamene mavuto amayambira, chifukwa masitolo ogulitsa magalimoto amakhala ndi zosankha zambiri.
Malo opangira magalimoto Vodi.su ayesa kuthana ndi mutuwu.
Makhalidwe a jacks
Magawo ofunikira:
- kuchuluka kwa katundu;
- kukweza kutalika;
- kutalika kwa tsinde;
- mtundu wamagalimoto - zimango, ma hydraulics, pneumatics.
Kunyamula katundu
Kwa magalimoto, ma crossovers apakati, minivans, mphamvu yonyamula matani 1-1,5 ndiyokwanira. Simukuyenera kukweza galimoto yonse, kungokweza mbali imodzi pang'ono kuti gudumu lichoke.
Magalimoto apamsewu amafunikira zida zamphamvu kwambiri, chifukwa nthawi zina mumayenera kukweza kutsogolo kapena kumbuyo kwagalimoto kuti muyikoke pamsewu. Ngati mumasankha magalimoto, ndiye kuti mutengere mphamvu zawo, mwachitsanzo, KAMAZ yokha imalemera matani 5-6, kuphatikizapo imatha kunyamula matani 15 a katundu. Chifukwa chake, gulani chipangizo chopangidwira matani 10-15.
Kukweza kutalika
Nthawi zambiri ndi 30-50 centimita, zomwe zimakwanira pamtunda wathyathyathya. Pamalo operekera chithandizo, ma jacks okhala ndi kutalika kwa tsinde yayitali amagwiritsidwa ntchito. Komanso, kutalika kwakukulu kudzafunika kwa ma SUV otsekeredwa m'matope.
kutalika kwapang'onopang'ono
Mwachidule, uku ndi kutalika kwa jack. Ndiko kuti, nyamulani kuti ikhale pansi pa galimoto. Ngati chilolezocho chiri chapamwamba, ndipo zowumitsa zili pamwamba pamtunda, ndiye kuti chipangizocho chiyenera kuwafikira mosavuta.
mtundu wa drive - parameter iyi imafuna kuganiziridwa mwatsatanetsatane, kotero tipereka gawo lina kwa izo.
Mitundu ya jacks
Mankhwala
Chosavuta - ndi makina pagalimoto. Kawirikawiri, chipangizo chamtundu wa screw chimaphatikizidwa mu phukusi, ndipo rack-and-pinion ndizoyenera ma SUV. Onse a iwo ndi odalirika ndithu.
Ubwino wa screw Jacks:
- kutenga malo ochepa;
- wokhazikika kwambiri;
- pali malo mwachilungamo lonse kutsindika pa stiffener wa galimoto.
Koma kuchotsera kwawo ndikuti muyenera kuyesetsa kwambiri kuti munyamule - muyenera kuzungulira wononga ndi chogwirira chomwe chimagwira ntchito ngati lever.
Rack, kapena monga amatchedwanso - High Jack Lift:
- kutalika kokweza - mpaka mita kapena kuposerapo;
- amatha kugwira ntchito zambiri zowonjezera - winch, lift, chipangizo chopangira ma gudumu;
- kukhazikika, kudalirika.
Zowona, kachiwiri, muyenera kuyesetsa kukweza, pansi pa galimoto payenera kukhala nsanja zapadera zoyika mbedza ya tong. Komabe, High Jack Lift imafunidwa kwambiri ndi okonda zapamsewu.
Palinso mitundu ina ya jacks makina: scissor mtundu kapena rolling. Zotsirizirazi ndi zabwino chifukwa simuyenera kuda nkhawa kuti galimoto idzaterereka kapena jack idzagudubuza.
Hayidiroliki
Hydraulic imakhalanso ndi mitundu yambiri yokwanira. Chowonjezera chawo chachikulu ndikuti simuyenera kuchita khama kuti mukweze, ingolowetsani lever ndikupopera silinda ya hydraulic, ndodo imakweza katunduyo popanda kutengapo gawo la mphamvu yanu yamphamvu.
Zofala kwambiri ndi majekesi a botolo. Zitha kukhala ndodo imodzi, kapena ndodo ziwiri, chifukwa chomwe kutalika kwake kumawonjezeka kwambiri.
Ubwino wawo waukulu:
- nsanja yayikulu yothandizira, mwayi wocheperako wogubuduza;
- kunyamula kwakukulu - kuchokera tani imodzi mpaka 50;
- kudalirika - Jack adapangidwa kuti athe kukweza kulemera kwake kowerengedwa kuphatikiza 25 peresenti, koma ngati katunduyo ndi wolemera kwambiri, ndodoyo imasiya kukwera;
- mawonekedwe osavuta komanso ophatikizika, amatenga malo ochepa;
- kulemera kochepa.
Kuchokera pazomwe takumana nazo, timati jack 1-2 ton ndi yokwanira ngakhale ma sedan a kalasi D kapena E. Ndiosavuta kugwira nawo ntchito, komabe, pogwiritsa ntchito pafupipafupi, silinda ya hydraulic sitha kupirira, ndiyeno mafuta amayamba. kutuluka kunja. Pankhaniyi, muyenera kuwonjezera mafuta a hydraulic nthawi zonse. Iwo ndi angakwanitse ndithu malinga ndi mtengo.
Ma rolling hydraulic jacks adziwonetsa okha bwino. Iwo ndi chimango pa mawilo amene amayendetsa pansi pa galimoto. Chowonjezera chachikulu ndikuti silinda ya hydraulic imapezeka molunjika, ndipo mukayamba kukakamiza mkati mwa silinda ndi lever kapena pedal, imakwera pamakona, ndiyeno ndodo imayamba kukulirakulira.
Makhalidwe abwino ndi awa: Kuchita bwino kwambiri, kuthamanga kosalala, kuchuluka kwa katundu. Zipangizo zogudubuza nthawi zambiri zimagwiritsidwa ntchito m'malo operekera chithandizo, motero amakweza hatchback ya A-class ndi galimoto yonyamula chimango.
Palinso mitundu yomwe kukakamiza kumapangidwa pogwiritsa ntchito mota yamagetsi yolumikizidwa.
Pneumo-hydraulic, pneumatic
Pneumo-hydraulics amagwira ntchito mofanana ndi ma twin-tube gas shock absorbers, ndiko kuti, pali chipinda chamafuta ndi chipinda chojambulira mpweya. Pneumatic ndi masilinda omwe amadzazidwa ndi mpweya.
Amawonedwanso nthawi zambiri m'malo operekera chithandizo. Ubwino wofunikira kwambiri ndikuti amapopedwa ndi kompresa kapena mpweya wochokera ku muffler. Palinso zovuta: muyenera kunyamula kompresa ndi hoses ndi zolumikizira ndi inu, iwo amatenga malo ambiri pamene deflated, chipinda akhoza kulasidwa mwangozi.
Zotsatira. Monga mukuonera, pali zambiri zoti musankhe. Ngati simugwiritsa ntchito jack nthawi zambiri, ndiye kuti wononga kapena mtundu wa botolo la hydraulic udzakhala wokwanira. Kwa magalimoto olemera kwambiri, njira yabwino kwambiri ndi ma hydraulic okhala ndi mphamvu yokweza matani asanu kapena kupitilira apo.
