nws yog dab tsi? Pros thiab cons

Tham txog SUVs ntawm peb lub vev xaib, peb tau hais tias muaj peb yam tseem ceeb ntawm lub cev qauv:

• ncej - UAZ-Patriot, Mitsubishi L200, Jeep Wrangler thiab lwm yam;
• load-bearing lub cev - yuav luag tag nrho cov sedans thiab hatchbacks;
• integrated ncej.

Qhov ntawd tsuas yog kev sib koom ua ke, peb yuav mob siab rau cov kab lus no.

Txhawm rau daws cov ntsiab lus, koj yuav tsum xub nco ntsoov txog cov qauv ntawm ob hom. Yog li, ib lub tsheb zoo tib yam yog cov qauv zoo ib yam li tus ntaiv. Nws lub ntsiab tseem ceeb yog spars thiab crossbars, interconnected los ntawm txoj kev welds, rivets, bolts ntawm muaj zog.

Xws li ib tug thav duab muab siab rigidity ntawm lub platform thiab ib co kev ywj pheej ntawm lub cev - nws muaj peev xwm txav mus rau tus txheeb ze ntawm tus ncej, uas yog ib qho tseem ceeb thaum tsav tsheb off-txoj kev los yog thaum nws los txog rau tsheb thauj khoom. Lub tsheb tavxij txuas nrog lub platform nrog rivets lossis bolts, thiab cov khoom siv roj hmab ntxiv yog siv los ua lub hauv ncoo vibrations.

Cov kabmob lub cev lossis lub hauv paus - lub cev yog kev sib koom ua ke nrog tus ncej thiab yog ib qho nrog nws. Peb tuaj yeem hais tias lub tsheb tavxij yog welded rau lub thav duab, lossis, nyob rau hauv cov ntaub ntawv ntawm ntau lub tsheb niaj hnub, lub tsheb tavxij nrog tus ncej yog stamped los ntawm ib daim hlau. Qhov kev tsim no yog txaus nyiam rau cov chaw tsim khoom rau nws lub teeb, tab sis tib lub sijhawm, kev nplij siab raug kev txom nyem - txhua qhov tsis sib xws tau pom tias mob hnyav heev. Raws li, lub tsheb ntawm qhov kev tsim no tsuas yog tsav los ntawm ntau lossis tsawg txoj kev tiaj tus.

Ib qho kev sib xyaw ua ke (ncej-lub cev qauv) yog qhov hloov pauv hloov ntawm ob hom tau piav qhia saum toj no.

Nws lub ntsiab parameter:

• lub thav duab ntawm lub spars yog inextricably txuas rau lub cev nrog kev pab los ntawm welds;
• lub cev yog tsis sib cais thiab siv tag nrho cov loads ntawm ib tug par nrog lub platform;
• muaj tag nrho-fledged spars txuas rau pem hauv ntej thiab nram qab ntawm lub tsheb;
• crossbars yog siv los txhav.

Nws yog qhov tseeb tias cov tuam ntxhab tau txhim kho kev tsim qauv ntawm cov cab kuj ntawm cov tsheb, yog li nyob rau hauv tag nrho cov keeb kwm ntawm kev lag luam automotive, ntau hom thiab subspecies ntawm ntau yam qauv tau tshwm sim, tab sis yog tias peb coj, piv txwv li, ib tug ncej SUV thiab ib tug. SUV nrog ib tug integrated ncej, qhov txawv yog pom tseeb:

• thav duab - kev sib txuas ntawm tus ncej thiab lub cev yog detachable, uas yog, tsis muaj teeb meem ntau, koj tuaj yeem tshem tawm lub cab thiab rov nruab nws ntawm lub platform tshiab;
• thav duab-lub cev txhawb nqa qauv - koj tuaj yeem tshem tawm lub cab tsuas yog nrog kev pab ntawm lub tshuab txiav, txiav nws tawm.

Raws li, lub cev sib xyaw ua ke muaj ntau dua nrog cov neeg nqa khoom, qhov sib txawv tsuas yog nyob rau hauv cov ntsiab lus: thawj zaug siv tag nrho-fledged spars, qhov thib ob siv subframes uas tuaj yeem nyob rau hauv pem hauv ntej ntawm lub tsheb hauv qab lub cav thiab gearbox, lossis tsuas yog pem hauv ntej thiab nram qab kom nruj.

Raws li cov saum toj no, cov lus xaus hauv qab no tuaj yeem kos:

• load-bearing lub cev - ib qho kev xaiv zoo tshaj plaws rau cov tsheb me thiab nruab nrab uas feem ntau txav mus rau qhov zoo tshaj plaws asphalt pavement;
• integrated ncej - yuav luag tag nrho cov SUVs (crossovers), pickups, me me thiab nruab nrab SUVs, 5-7-seater minivans;
• thav duab kev tsim kho - tag nrho-loj crossovers thiab SUVs, tsheb thauj khoom, tsheb npav, minibuses, tshuab ua liaj ua teb, tsheb sib tw.

Qhov zoo thiab qhov tsis zoo

Lub thav duab-lub cev tsim tsis tuaj yeem ua tau zoo, txawm li cas los xij, zoo li lwm yam, txawm li cas los xij, nws yog qhov nrov rau ntau yam:

• txheeb ze yooj yim ntawm kev sib dhos - thav duab yog welded rau lub cev nyob rau hauv lub khw welding, tsis muaj ntxiv fasteners;
• loads yog sib npaug ntawm tag nrho cov nto;
• vim nws qhov hnyav dua, lub tsheb tau yooj yim rau kev tsav tsheb;
• nce torsion zog - lub cev yuav tsis deformed thaum lub sij hawm nres nres, khoov, thaum overloads.

Kuj tseem muaj cons:

• complexity ntawm kev kho - lub thav duab integrated tsis tuaj yeem kho, tsuas yog welded, tshwj xeeb tshaj yog tias corrosion tau tshwm sim;
• inferior nyob rau hauv lub zog rau lub thav duab platform;
• hlau qaug zog sai tsim nyob rau hauv cov welds, uas ua rau kom ceev ceev nrog ib tug txhoj puab heev tsav style.

Nws tseem yuav tsum tau muab sau tseg tias txhua yam muaj nws cov drawbacks, vim nws yog tsis yooj yim sua kom ua tiav qhov zoo tagnrho.
