Txhim kho Leaf Spring Suspension

Composite rear nplooj caij nplooj ntoos hlav cog lus ntau adaptability thiab tsawg zog.

Hais txog lo lus "nplooj nplooj ntoos hlav" thiab muaj kev nyiam xav txog cov tsheb loj hauv tsev kawm ntawv uas tsis muaj kev sib tw, lub laub-sprung, khoom qag tom qab kawg los yog, hauv cov ntsiab lus maus taus, cov tsheb kauj vab ua ntej nrog cov nplooj hlav sab hauv.Txawm li cas los xij, tam sim no peb tab tom saib txog kev txhawb nqa lub tswv yim rau motocross tsheb kauj vab.

Nyob rau hauv qhov tseeb, thaum crude, qub ncua kev kawm ntawv feem ntau siv nplooj springs, lub caij nplooj ntoos hlav nws tus kheej tsis yog feem ntau yog lub hauv paus ntawm lawv tsis muaj sophistication.Chevrolet's Corvette tau siv cov nplooj ntoo hla hla ntawm kev ncua kev ywj pheej los ntawm tiam thib ob hauv xyoo 1963 mus txog rau thaum lub sijhawm thib yim xyoo 2020, siv cov yas sib xyaw ib-nplooj nplooj hlav hauv 80s.Tsawg famously, Volvo siv composite, transverse nplooj springs nyob rau hauv ob peb ntawm nws cov qauv tshiab.Siv kom raug, nplooj nplooj hlav ua los ntawm cov ntaub ntawv niaj hnub tuaj yeem sib zog dua li cov hlau coils, thiab qee qhov lawv cov duab ntev, tiaj tus yog yooj yim rau pob.Composite nplooj springs, ua los ntawm ib tug ib thooj es tsis yog cov stacked nplooj ntawm cov tsoos hlau nplooj springs, kuj zam kev sib txhuam ntawm ntau nplooj rubbing ua ke, uas yog ib tug ntawm cov tseem ceeb drawbacks ntawm cov laus tsim.
Nplooj springs tau tshwm sim nyob rau hauv motocross tsheb kauj vab nyob rau hauv lub niaj hnub era ua ntej.Yamaha's 1992-93 Hoobkas 'crosser, YZM250 0WE4, siv ib daim ntawv sib xyaw ntawm lub nraub qaum, nws pem hauv ntej kawg clamped nyob rau hauv lub cav thiab lub rear bolted mus rau ib tug linkage hauv qab lub swingarm, yog li raws li lub rear log sawv, nplooj flexed rau. muab springing.Lub tswv yim yog kom tshem tawm qhov chaw uas lub caij nplooj ntoos hlav tom qab thiab damper yuav nquag zaum, tso cai rau txoj kev nkag ncaj nraim rau lub cav.Lub compact, rotary damper kuj haum thiab lub tsheb kauj vab yog kev sib tw khiav hauv 1992 thiab 1993 hauv All-Japan Championship.
Peb cov qauv tsim tshiab, tau tshaj tawm hauv daim ntawv thov patent los ntawm lub tuam txhab Austrian, hais txog Yamaha thiab taw qhia cov txiaj ntsig zoo sib xws ntawm kev ntim khoom, tab sis siv cov txheej txheem sib txawv.Raws li pom nyob rau hauv cov duab, peb muab cov nplooj nyob rau hauv ib tug ze li ntawm ntsug orientation, nruj nreem tiv thaiv lub rear ntawm lub cav kom tshem tawm qhov chaw ib txwm sau los ntawm ib tug coilover (tus patent paub meej tias thaum nws ua duab qhia tau hais tias lub system overlaid ntawm ib daim duab ntawm ib tug coilover. cov pa motocrosser, lub caij nplooj ntoos hlav coil qhia hauv daim duab yuav tsis nyob).

Sab saum toj thiab hauv qab ntawm lub caij nplooj ntoos hlav yog txhua tus khov kho clamped mus rau qhov kawg ntawm kev sib txuas.Cov kev sib txuas sab saud yog pivotally mounted ntawm lub tsheb kauj vab lub ntsiab ncej, thaum lub qis txuas pivots los ntawm ib tug bracket nyob rau hauv lub swingarm.Qhov tshwm sim yog tias, thaum lub viav vias txav mus rau sab saud, khoov tau nkag mus rau lub caij nplooj ntoos hlav sib xyaw.Txhawm rau ntxiv kev hloov kho, qhov txuas sab sauv qhov ntev yog kho tau los ntawm cov ntsia hlau xov thiab lub qhov rooj kho kom haum, ua rau nws yooj yim kom nce lossis txo qis hauv qhov system.Daim ntawv patent tsis qhia lub damper rau lub rear kawg tab sis nws cov ntawv qhia tau hais tias ib tug pa damper yuav siv los tswj lub rear ncua kev kawm ntawv.Txawm li cas los xij, nws yuav tsum tau ua kom zoo dua li qhov kev poob siab tom qab ib txwm, los yog sib txawv, kom KTM coj kom zoo dua cov txiaj ntsig ntawm nplooj nplooj hlav, uas feem ntau cuam tshuam rau qhov chaw nws tso tawm.Daim ntawv pov thawj pom zoo tias qhov chaw no tuaj yeem siv los ua cov khoom siv hluav taws xob xws li lub tshuab cua, lub tshuab nqus tsev, lossis cov muffler, piv txwv li, loj dua lossis ntau dua.Tsis tas li ntawd, tus qauv tsim tuaj yeem tso cai rau kev hloov pauv ntau dua ntawm kev teeb tsa yav tom ntej hluav taws xob motocross tsheb kauj vab.

Tshaj li qhov zoo ntawm kev ntim khoom, lub kaw lus lwm qhov txiaj ntsig yog nws qhov kev hloov kho.Peb patent qhia tau hais tias hloov qhov ntev los yog cov duab ntawm cov kev sib txuas uas tuav ob qho kawg ntawm lub caij nplooj ntoos hlav tuaj yeem hloov qhov kev ncua tus cwj pwm.Nyob rau hauv ib qho piv txwv (Fig.7 nyob rau hauv patent), plaub lub zog sib txawv tau pom tias yuav hloov lub rear ncua kev kawm ntawv tus cwj pwm: hloov ntawm nce tus nqi (7a) mus tas li tus nqi (7b), thiab txo lub caij nplooj ntoos hlav nqi (7c thiab 7d).Cov cwj pwm txawv txawv no tau ua tiav yam tsis hloov lub caij nplooj ntoo hlav nws tus kheej.
Raws li ib txwm muaj, daim ntawv thov patent tsis tau lees paub tias lub tswv yim yuav ncav cuag ntau lawm, tab sis qhov zoo ntawm cov khoom ntim ntawm nplooj nplooj hlav tom qab kawg tuaj yeem ua qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau yav tom ntej raws li hluav taws xob hluav taws xob yuam cov engineers kom rov xav txog cov qauv txheej txheem uas tau raug honed thaum lub sij hawm ib xyoo pua ntawm piston-cav tsheb kauj vab.
