Lub luag haujlwm ntawm lub chassis yog txhawb nqa thiab nruab lub cav tsheb thiab nws cov khoom siv thiab cov khoom sib dhos ua kom lub tsheb tag nrho, thiab tau txais lub zog ntawm lub cav kom lub tsheb txav mus los thiab ua kom muaj kev tsav tsheb zoo. Lub chassis muaj plaub yam: kis tau tus mob system, tsav tsheb, kauj thiab braking system.
duab
Daim duab 1 Tsheb chassis
Tsav tsheb ciav hlau
Cov kis tau tus mob feem ntau muaj clutch, kis tau tus mob, universal kis ntaus ntawv, lub ntsiab reducer, sib txawv thiab ib nrab ncej.
Kev ua haujlwm ntawm kev tsav tsheb ciav hlau
Lub zog tsim los ntawm lub cav tsheb yog xa mus rau lub log tsav los ntawm kev sib kis. Cov kis tau tus mob muaj zog xws li deceleration, hloov ceev, thim rov qab, lub zog cuam tshuam, inter-wheel differential thiab inter-axle differential. Nws ua haujlwm nrog lub cav kom ntseeg tau tias kev tsav tsheb ib txwm muaj nyob rau hauv ntau yam kev ua haujlwm thiab muaj lub zog zoo thiab kev ua haujlwm zoo. Kev lag luam.
Hom thiab muaj pes tsawg leeg ntawm tsav tsheb ciav hlau
Cov kis tau tus mob tuaj yeem muab faib ua cov tshuab sib kis, hydraulic kis tau tus mob, hydraulic kis tau tus mob, hluav taws xob kis tau tus mob, thiab lwm yam.
1. General muaj pes tsawg leeg thiab layout ntawm mechanical kis system (saib daim duab 2).

Daim duab 2 Schematic layout ntawm pem hauv ntej-mounted, longitudinal-mounted cav thiab rear-log tsav
Schematic daim duab ntawm lub layout ntawm 4 × 2 lub tsheb nrog ib txwm engine ntsia longitudinally nyob rau hauv pem hauv ntej ntawm lub tsheb thiab rear qag tsav. Lub zog tsim los ntawm lub cav yog xa mus rau lub qag tsav los ntawm lub clutch, kis tau tus mob, thiab universal kis ntaus ntawv. Ntawm lub transaxle, lub zog xa mus rau lub log tsav los ntawm qhov kawg reducer, qhov sib txawv thiab ib nrab shafts.

Daim duab 4 Schematic daim duab ntawm hydraulic mechanical kis tau tus mob
Hydraulic kis tau tus mob (ntawm no yog hais txog hydrodynamic kis tau tus mob nkaus xwb) siv cov kev hloov nyob rau hauv kinetic zog ntawm cov kua nruab nrab thaum lub sij hawm cyclic ntws ntawm lub active caij thiab lub zog tsav mus rau kis tau tus mob. Lub tshuab hluav taws xob kis tau tus mob yog txuas nrog hauv series nrog cov kauj ruam kev sib kis. Qhov kev sib kis no yog hu ua hydromechanical kis.

Daim duab 5 Schematic daim duab ntawm hydrostatic kis system
Hydraulic kis tau tus mob, tseem hu ua hydrostatic kis tau tus mob, kis tau lub zog los ntawm kev hloov nyob rau hauv lub static siab zog ntawm cov kua kis nruab nrab. Nws yog tsim los ntawm lub cav-tsav roj twj tso kua mis, hydraulic lub cev muaj zog thiab tswj cov cuab yeej.

Hauv kev xa hluav taws xob, lub cav tsav lub tshuab hluav taws xob tsim hluav taws xob, thiab tom qab ntawd lub tshuab hluav taws xob tsav lub transaxle lossis lub tshuab hluav taws xob ncaj qha tsav lub log tsav nrog lub reducer.
Tsav tsheb ciav hlau layout
Qhov kev teeb tsa ntawm cov tshuab xa hluav taws xob feem ntau yog cuam tshuam nrog qhov chaw ntawm lub cav thiab hom tsav ntawm lub tsheb. Nws tuaj yeem muab faib ua:
1. Pem hauv ntej-cav thiab rear-log tsav-FR: uas yog, pem hauv ntej-engine thiab rear-log tsav
Qhov no yog ib txoj kev cai. Feem ntau cov tsheb thauj khoom, qee lub tsheb thiab qee lub tsheb npav hauv tsev thiab txawv teb chaws txais yuav hom no. Nws yog pem hauv ntej-log rau rear-log tsav. Lub cav tso zis hluav taws xob yog xa mus rau lub qag tsav los ntawm lub clutch-transmission-transmission ncej. Tom qab decelerating thiab nce torque, nws yog kis mus rau lub rear sab laug thiab sab xis ib nrab-shafts tsav lub rear log kom lub tsheb khiav. Txhua lub log ua nws tus kheej lub luag haujlwm, lub kauj thiab tsav tsheb sib cais, thiab cov khoom xa tawm kuj tseem sib xws.
2. Tsheb-mounted thiab rear-log tsav-RR: rear-mounted engine thiab rear-log tsav
Qhov kev teeb tsa no feem ntau yog siv rau cov tsheb npav loj, thiab cov tsheb me me thiab lub teeb me me kuj siv qhov kev teeb tsa no. Lub rear-mounted engine ua rau pem hauv ntej qag tsis tshua muaj overloaded thiab ua rau tag nrho cov kev siv ntawm lub pob tw cheeb tsam. Nws tuaj yeem ua tau zoo txo qhov siab ntawm lub cev hauv pem teb lossis ua kom tag nrho siv qhov chaw hauv qab hauv pem teb hauv nruab nrab ntawm lub tsheb los tso lub nra. Nws kuj tseem pab tau kom txo tau qhov cuam tshuam ntawm qhov kub thiab txias thiab suab nrov ntawm lub cav. Tsav tsheb cuam tshuam. Qhov tsis zoo yog tias lub cav txias txias tsis zoo, thiab qee qhov kev ua txhaum thaum tsav tsheb tsis yooj yim pom los ntawm tus neeg tsav tsheb. Kev tswj chaw taws teeb kuj tseem ua rau kev tswj cov txheej txheem nyuaj thiab kev saib xyuas thiab kev hloov kho tsis yooj yim. Txawm li cas los xij, vim nws qhov zoo tshaj plaws, nws tau siv ntau hauv cov tsheb npav loj.
3. Pem hauv ntej-cav-FF: pem hauv ntej-cav, pem hauv ntej-log tsav
Hom no muaj ib qho yooj yim kev khiav hauj lwm mechanism thiab zoo engine kub dissipation tej yam kev mob. Txawm li cas los xij, thaum nce toj, qhov loj ntawm lub tsheb txav mus rau sab nraud, uas txo qhov kev sib txuas ntawm lub log tsav pem hauv ntej thiab ua rau lub log tsav nws yooj yim dua; thaum braking downhill, qhov loj ntawm lub tsheb txav mus rau pem hauv ntej, ua rau lub log pem hauv ntej overloaded thiab overturning ntawm high speeds. Feem ntau cov tsheb tam sim no txais qhov kev teeb tsa no.
4. kis tau tus mob ntawm off-road tsheb
Cov tsheb off-road feem ntau yog tag nrho cov log tsav nrog lub cav pem hauv ntej thiab cov ntaub ntawv hloov mus tom qab lub gearbox kom xa lub zog mus rau txhua lub log. Tam sim no, lub teeb off-txoj kev tsheb feem ntau siv 4 × 4 tsav hom, nruab nrab-loj off-road tsheb siv 4 × 4 lossis 6 × 6 tsav hom; hnyav off-road tsheb feem ntau siv 6 × 6 los yog 8 × 8 tsav hom.
