Dab tsi yog Qhov Sib Txawv Ntawm Cov Hlau Thiab Txhuas Tswj Cov Caj Npab? Phau Ntawv Qhia Txog Cov Khoom Siv Hauv Corolla's Control Arms.

Koj mus rau lub chaw muag khoom 4S thiab hloov koj lub caj npab tswj thiab tus kws kho tsheb qhia rau koj, "Tus thawj yog hlau, koj puas xav them nyiaj ntxiv rau txhuas?" Koj tsis meej pem- tsis yog lawv txhua lub pob hlau? Nws yuav ua tau ntau npaum li cas?
Qhov txawv yog loj.
Niaj hnub no, peb tab tom siv Toyota Corolla uas paub zoo tshaj plaws los ua "cov cuab yeej qhia" kom nthuav dav qhov sib txawv ntawm cov hlau thiab txhuas tswj caj npab. Tom qab nyeem qhov no, tsis tsuas yog koj paub tias yuav xaiv qhov twg, tab sis koj kuj paub tias yog vim li cas Toyota xaiv cov hlau hla txhuas rau nws Corolla.
Cov ntsiab lus: Corolla yog ua los ntawm cov hlau, uas yog "cov hlau ntse."
Ntau tus neeg xav txog Corolla ua "khoom noj," yog li cov khoom siv yuav tsum pheej yig.
Tsis yog. Lub caj npab tswj ntawm lub Corolla siv siab -lub zog steel (FB780, lub zog 800-}950 MPa). Lub caj npab tswj sab sauv yog welded nrog ob - txheej stamping steel daim hlau thiab sab caj npab tswj yog welded nrog ib lub phaj siab.
Nws tsis yog hais txog kev txiav cov ces kaum; Toyota tau suav tias nrog ntau tshaj 50 lab Corolla muag thoob ntiaj teb, kev tswj tus nqi yog qhov tseem ceeb tshaj plaws. Chav tsev nqi ntawm steel tswj caj npab yog 80-150 yuan tsawg tshaj li ntawm txhuas tswj caj npab. Muaj ntau tshaj kaum lab lub tsheb hauv Tshuag thiab cov nqi txuag yog astronomical.
Tsis tas li ntawd, siab - lub zog steel muaj qhov zoo dua uas tsis muaj txhuas: nws muaj kev qaug zog.
Qhov no txhais li cas? Thaum rov ntaus dua, cov hlau tuaj yeem theoretically tiv thaiv tus naj npawb ntawm cov voj voog uas tsis muaj kev tawg, tsuav yog qhov kev ntxhov siab qis dua ib qho chaw pib (kwv yees li 40 txog 60 feem pua ​​​​ntawm nws lub zog). Yog li cov hlau tswj caj npab muab lus ceeb toom rau koj ua ntej nws ua tsis tiav - suab nrov txawv txav, txav tsis tau, pob sib koom ua ke- muab sijhawm rau koj kho nws.
Yuav ua li cas yog aluminium? Aluminium, tshwj xeeb, tsis muaj kev txwv kev qaug zog. Txawm tias thaum lub siab qis, tom qab lub voj voog txaus, nws tuaj yeem tawg, feem ntau tsis ceeb toom. Tias yog vim li cas ntau tus neeg tsav tsheb tau hais tias, "Steel qhov kawg, aluminium qhov kawg."
Yog li Corolla xaiv cov hlau tsis yog vim nws "siab-kawg" tab sis vim nws yog "txhim kho" - nws qhia koj thaum koj xav hloov nws ua ntej thiab tsis dheev cia koj tso tseg.
ii. Dab tsi yog qhov zoo ntawm aluminium tswj caj npab? Peb lo lus: hnav, nruj, xeb resistant.
Yog cov hlau zoo heev, vim li cas BBA (BMW, Mercedes-Benz, Audi) thiab cov tsheb tshiab zog tig mus rau txhuas?
Vim tias aluminium muaj peb qhov zoo uas steel tsis:
Ua ntej, nws yog lub teeb yuag. Lub teeb zoo kawg.
Aluminium yog li ntawm ib qho - peb li ntom li hlau. Aluminium tswj caj npab yog 25% mus rau 40% sib zog dua cov hlau. Tej zaum koj yuav xav tias, "Puas yog qhov pheej yig ntawm ob peb puas grams xwb?"
Yog, nws yog. Vim hais tias kev tswj caj npab yog ib feem ntawm cov khoom tsis muaj zog - ib txheej ntawm qhov chaw (lub log hub, nres disc, tswj caj npab, txuas rods, thiab lwm yam) hauv qab lub caij nplooj ntoos hlav. Qhov hnyav poob unsprung loj yog "leveraged":
Rau txhua kilogram ntawm unsprung loj poob, muaj ib tug txo ntawm 5-8 kilograms ntawm sprung huab hwm coj (piv txwv li, lub tsheb lub cev loj).
Lub caj npab tswj tuaj yeem txo qhov hnyav los ntawm 0.5kg, thaum plaub lub log ntxiv txog 2kg, uas sib npaug rau 10-16kg tawm ntawm lub cev. Qhov no sawv cev rau kev txhim kho hauv kev tuav thiab kev nplij siab.
Qhov no yog vim li cas lub zog tshiab tsheb tau nce siv aluminium tswj caj npab-cov khoom siv hluav taws xob hauv tsev hluav taws xob tswj kev lag luam loj yog kwv yees kom tshaj $ 28 nphom los ntawm 2025, nrog 75% nkag mus rau lub zog tshiab. Ib nrab ntawm 4 mus rau 7 feem pua ​​​​nce yog vim li no zoo li tsis tseem ceeb aluminium Cheebtsam.
Qhov thib ob, lawv yog cov nruj heev thiab teb.
Aluminium tswj caj npab, ua ke nrog zoo - tuned bushings, muab cov log ruaj khov kho kom ruaj khov rau lub kauj tsheb kom pom tseeb dua thaum lub kaum sab xis. Qhov kev txwv ceev yog nce los ntawm kev txo tus naj npawb ntawm lub cev yob thaum lub sij hawm siab - hloov txoj kab ceev.
Siv cov ntaub ntawv kev lag luam, aluminium tswj caj npab tuaj yeem txo qis inertial rog los ntawm kwv yees li 12% piv rau steel tswj caj npab thaum tig ntawm kev kub ceev. Tej zaum koj yuav tsis tau pom qhov txawv ntawm lub nroog, tab sis nws pom tseeb ntawm txoj kev loj.
Thib peb, tsis muaj xeb.
Aluminium yog ib txwm corrosive thiab tsis xav tau txheej ntxiv. Thaum lub sij hawm, steel tswj caj npab yuav xeb, tshwj xeeb tshaj yog nyob rau sab qaum teb, qhov twg de- cov tshuaj icing siv, sai dua. Aluminium Cheebtsam yog qhov zoo dua ntawm qhov no.
III. Aluminium kuj tuaj nyob rau hauv ntau qib: forged, cam khwb cia thiab extruded -qhov txawv yog dab tsi?
Tsis txhob xav tias txhua yam kev tswj hwm ntawm txhuas yog tib yam, vim tias lawv muaj "txhuas" hauv lawv lub npe. Aluminium tswj caj npab tuaj yeem muab faib ua peb qib raws li nws cov txheej txheem tsim khoom, thiab nws qhov kev ua tau zoo sib txawv:
Qib 1: Forged Aluminium (Sab saum toj Tier)
Forged los ntawm 6061 lossis 7075 aluminium alloy. Nws muaj cov qauv hauv kev cog lus, ob peb qhov tsis xws luag thiab qhov ua tau zoo tshaj plaws ntawm kev qaug zog ntawm ib qho ntawm peb hom txhuas, txawm tias ze rau qib ntawm cov hlau.
Tus nqi kuj yog qhov siab tshaj - kwv yees li peb npaug ntawm cov khoom hlau. BMW 5 Series, Mercedes-Benz E-Class thiab Porsche Macan txhua tus siv chav kawm.
Qib 2: Extruded Aluminium (Nruab nrab-Range)
Ua los ntawm 6082 aluminium alloy extrusion. pheej yig dua thiab muaj peev xwm ntau dua li forging, nws yog qhov kev xaiv tseem ceeb rau nruab nrab -andhigh- kawg lub zog tshiab. Tesla's Model 3 / Y tswj caj npab poob rau hauv pawg no. Qib 3: Cast Aluminium (Nrawm-Level)
Nws yog ua los ntawm A356 aluminium alloy thiab tuag- nrum tag nrho. Nws muaj tus nqi qis tshaj plaws tab sis nws yooj yim rau sab hauv porosity thiab shrinkage, lub zog qaug zog tsis zoo thiab lub neej kev pabcuam dav dav. Ntau qhov "aluminium alloy suspension" thaum ntxov tau ua tiav ntawm qib no thiab tuaj yeem ua yuam kev tom qab 100,000 txog 100,000 km.
Yog li thaum koj pom cov tsheb touting "aluminium alloy tswj caj npab," Triends tsis zoo siab heev - nug ua ntej yog tias nws yog cuav, nias lossis nrum. Cast aluminium tsis tas yuav muaj lub neej ntev dua li siab - lub zog steel, tab sis nws yeej tsis tuaj pheej yig.
Plaub, muaj "Hidden Player": LFT Plastic Control Arms
Cov khoom kub tshaj plaws hauv xyoo 2026 tsis yog txhuas, tab sis LFT ntev fiber reinforced yas.
Nws los hauv fiberglass lossis carbon-fibre- siv zog nylon matrix nrog qhov ceev ntawm tsuas yog 1.1 ~ 1.2 g / cm3, uas yog 30% ~ 38% ib xees sib zog dua aluminium, thiab muaj kev qaug zog thiab corrosion zoo dua li aluminium alloys, nrog rau cov nqi qis dua forged aluminium.
Kev lag luam muaj qhov tseeb hierarchy:
Nkag mus- qauv qauv, tus nqi ntawm $ 60,000 thiab $ 150,000, siv LGF30-PP, hloov cov khoom siv hlau, poob 35% mus rau 40% ntawm nws qhov hnyav thiab tus nqi kwv yees tib yam.
Mid -andhigh- cov qauv kawg nqi ntawm $150,000 thiab $350,000 siv LGF40-PA6 lossis LGF50-PA66. PA6 muaj qhov kub thiab txias tsis zoo, haum rau cov huab cua sab qaum teb, PA66 muaj qhov kub thiab txias tsis kam, haum rau lub ntsiab load bearing pem hauv ntej ncua kev kawm ntawv.
Tus nqi ntawm ntau tshaj $ 350,000, cov khoom kim heev flagship tsheb yog carbon fiber hybrid LFT uas poob ntau tshaj 40% ntawm nws qhov hnyav thiab muaj zog dua aluminium alloys. BMW X5, NIO ES8, Li Auto L9 thiab lwm yam qauv siv LFT.
Hauv kev nkag siab, LFT yog "qhov kawg teb" rau kev tswj cov riam phom hauv 2026 - sib dua li hlau, muaj zog dua aluminium, pheej yig dua txhuas thiab xeb- dawb. Toyota qhov kev xaiv 'kev xaiv ntawm cov hlau rau Corolla thaum kawg qhia txog lub logic uas tsev neeg lub tsheb yog "zoo txaus."
Rov qab rau Corolla: Koj yuav tsum xaiv cov hlau lossis txhuas?
Tom qab ntawd, ntawm no yog kuv lub tswv yim zoo tshaj plaws:
Yog tias koj lub Corolla yog ib tiam ntawm 2007 txog 2024, lo rau siab - lub zog steel tswj caj npab (48068-12290 / 48069-12290).
Yog vim li cas yooj yim: Corolla's chassis geometry yog geometrically tsim rau steel - tswj riam phom. Lub kaum sab xis ntawm lub pob taub hau, nruj ntawm bushing thiab installation txoj hauj lwm ntawm subframe yog tag nrho cov yam ntxwv ntawm cov hlau. Kev siv cov txhuas txhuas yuav ua rau nws sib zog, tab sis nws yuav cuam tshuam tag nrho qhov kev ncua sij hawm haum, uas ua rau muaj kev sib tsoo thiab nrov nrov.
Thaum twg aluminium yuav tsum tau txiav txim siab?
Tsuas yog nyob rau hauv ib qho xwm txheej: yog tias koj lub Corolla tau hloov kho nrog lub yob lossis mounted kev sib tw chassis, yuav tsum tau txo qhov hnyav hnyav heev. Nyob rau hauv cov ntaub ntawv no, kev hloov ntawm cov tswj caj npab nrog txhuas, ua ke nrog kev tuning, yuav cia koj txaus siab rau qhov zoo ntawm lub teeb yuag.
Nco ntsoov: tsis muaj cov khoom zoo kiag li, tsis muaj cov khoom phem kiag li, tsuas yog cov khoom tsim nyog, cov khoom tsis raug. Corolla lub steel tswj caj npab yog Toyota qhov kev pom zoo tshaj plaws, muag 50 lab tsheb.
VI. INTRODUCTION Ib kab lus cov ntsiab lus: Hlau tswj riam phom: txhim khu kev qha, pheej yig, ceeb toom ntxov rau "kev xaiv ncaj ncees" rau tsev neeg lub tsheb. Aluminium tswj caj npab: hnav, ceev thiab xeb-dawb, tab sis kim, sophisticated thiab unpredictable; tus "cov tub ntxhais kawm sab saum toj" hauv siab - tsheb ua haujlwm. Tsis muaj dab tsi tsis ncaj ncees lawm rau Corolla xaiv ua ncaj ncees.
