Tsheb chassis - yog dab tsi?

Tej tsheb, hais txog ntawm nws cov hom thiab lub hom phiaj, muaj peb lub ntsiab qhov chaw: lub cav lub cev thiab lub chassis. Lub tsheb chassis - ib tug system muaj tau koom ua ke ua ke poob lawm ntawm khiav iav, thiab cov kis tswj mechanism. Nws yog ib tug ntawm cov tseem ceeb tshaj plaws qhov chaw ntawm lub tsheb, raws li nws tso cai rau koj mus muab cov xaav thiab kis tau tus mob ntawm tag nrho cov rog kuj rau nws thaum uas tsav tsheb.

chassis muaj nuj nqi

Chev ncua kev kawm ntawv hais txo thiab txawm peem rau load hloov mus hloov los thaum tsav tsheb nyob rau hauv ib tug thawv txoj kev thiab off-road. Lub sub-ncej tso cai rau koj mus teem lub cev nyob rau hauv cov chassis, lub cav thiab lwm yam units. Lub pem hauv ntej thiab nram qab lub axles ntawm lub log yog kis tau los ntawm cov muab zog thiab yog li muab lub zog los ntawm lub tsheb.

Tus thawj tsheb nyob rau hauv lub xyoo pua xeem, muaj ib tug sib piv rau cov neeg uas mus rau hauv txoj kev niaj hnub no. Tag nrho cov tsheb - thiab tsheb thiab cov tsheb thauj khoom - siv kom muaj ib tug ncej uas yuav txhim kho tau tag nrho cov chav nyob thiab Cheebtsam (lub cev, kis tau tus mob, engine, etc ...). Thaum lub sij hawm, lub Academy ntawm Medical Sciences ntawm lub tsheb chassis tseem xwb nyob rau hauv cov tsheb thauj khoom thiab cov tsheb npav. Nyob rau hauv lub neeg nrog caij tsheb ncej muaj nuj nqi pib mus nqa tawm hauv lub cev.

kev faib ntawm lub chassis

Yog li, ib tug yuav paub qhov txawv ob tug sib txawv schemes chassis tsheb.

• Rams chassis, uas feem ntau muaj ob peb cov khoom beams, uas yog ntsia rau tag nrho cov qhov chaw hauv lub tsheb. Qhov no tsim pub tsheb thauj loj loads thiab yooj yim tiv nrog ib tug ntau yam ntawm dynamic loads.

• Monocoque. Nyob rau hauv pursuit ntawm ib tug txo nyob rau hauv lub ceeb thawj ntawm lub tsheb tag nrho cov ncej zog muaj tau muab kho rau hauv lub cev. Qhov no ncej tsis tau tsiv mus loj loads, tab sis nyob rau tib lub sij hawm muab ntau dua kev nplij siab thiab ceev.

Nyob ntawm seb lub tsheb siv, cov nram qab no ntawm cov lug yuav siv tau:

• spar;

• txha caj;

• peripherals;

• forked-txha caj;

• ntxaij ntoo.

Chassis cov tsheb thauj khoom

Feem ntau pom tau hais tias spar ncej. Lawv sawv cev rau lub ob longitudinal kab teeb kev cob cog rua ntawm tus ntoo khaub lig cov tswv cuab. Tus duab ntawm cov kab teeb yuav ua tau txawv heev: ib tug tubular, x- los yog C-puab. Nyob rau hauv lub feem ntau ntau loaded ib feem ntawm tus ncej tau tsam sectional sill. Parallel Circuit Court spars (beams positioned equidistant thoob plaws hauv lub chassis) yog siv rau cov tsheb thauj khoom. Lub tsheb yuav tsum muaj ntaub ntawv struts spars uas muaj ib co divergence nyob rau hauv ob qho tib si kab rov tav axis thiab tus ntsug dav hlau.

Txha caj ncej nruab nrab yog ib tug longitudinal txhawb beam uas yog mounted ntoo khaub lig tug tswv cuab. Feem ntau, qhov no beam muaj ib tug yeej tus ntoo khaub lig seem, yog li ntawd nws yuav tsum npaj kis tau tus mob ntsiab. Xws li ib tug ncej muab ntau dua kuj mus Torsion tshaj spars. Cov kev siv ntawm tus txha caj chassis hom yuav siv cov kev ywj siab ncua kev kawm ntawv rau tag nrho cov log.

Txha caj-forked ncej longitudinal beam muaj ib tug ceg nyob rau hauv lub rear los yog pem hauv ntej feem. Hais tias yog, nws combines cov spars thiab sill.

Tus so ntawm lub chassis ncej yog tsis siv rau cov tsheb thauj khoom.

Tus lwm yam ntsiab lus ntawm cov lo lus

Dhau li cov saum no txhais, lo lus "chassis" yog siv los piav cov self-propelled tsheb npaj rau installation ntawm ntau yam cov cav thiab mechanisms. Tsis tas li ntawd, qhov no lub sij hawm yog siv nyob rau hauv hais tias ib feem ntawm lub aircraft, uas yog siv rau kev tshem nyob rau airfield, ntawm takeoff thiab tsaws. Raws li yog cov ntaub ntawv nrog tsheb chassis, qhov no daim softens shocks thiab loadings thaum lub sij hawm av zog ntawm aircraft. Aircraft yuav tsaws iav, tsis zoo li lub tsheb tej zaum yuav muaj ib tug qauv nrog lub log, skis los yog floats.

Feem ntau tus nqi ntawm cov chassis lus tsis meej pem nrog lub tsheb tsav tswvyim. Tsis yog txhais lus rau cov nqe lus vim lub fact tias lawv yog yuav luag ib tug thiab tib sab ntawm lub tsheb. Tsheb tswv dawb do hais tias lawv lub tsheb muaj ib tug 4x2 chassis. Tab sis nws yuav tsum tau to taub hais tias 4x2 - nws yog ib tug layout tswvyim, tawm ntawm uas tus naj npawb ntawm cov tsav tsheb log nrhiav tau, tab sis tsis muaj ntau. Hais txog qhov kev tib yam, hais tias qhov no chassis tau hais saum toj no. Txawm tias muaj tseeb hais tias cov log tsheb thiab cov tsav yog muaj nyob rau hauv lub chassis system yog tsis tsim nyog rau siv lub sij hawm xwb rau qhov no nqaim hauj lwm.

hom ntawm kev ncua

Lub tsheb chassis yuav muaj ntau hom kev ncua kev kawm ntawv:

a) Associates:

• rau longitudinal nplooj springs;
• paired nrog phau ntawv no caj npab;
• nrog ob tug longitudinal levers;
• drawbar;

b) ywj siab.

Raug tshem tawm nruab nrog levers, pawm no ntau npau, kev poob siab absorbers thiab springs. Lub hom phiaj tseem ceeb ntawm lub tsheb los ua ke yog qhov haum ntawm deeg thiab oscillations thaum lub sij hawm lub zog. Lub pem hauv ntej thiab nram qab lub ncua yog cov sib txawv, vim cov steered log tsim yuav tsum tau siv los ntawm ntau txoj kev sibtham.
