Active thiab semi-active ncua kev kawm ntawv: ua hauj lwm

Ntau zuj zus, ntawm cov qauv high-end (thiab tsawg thiab tsawg dua ntawm Citroëns ...) active thiab semi-active suspensions nrhiav kev los txhim kho kev nplij siab (tshwj xeeb tshaj yog rau cov nquag nquag) thiab hloov qhov ncua sij hawm calibration ntawm kev thov. Yog li cia wb mus saib lub ntsiab technologies uas twb muaj lawm.

Saib ntxiv: kev ua haujlwm ntawm kev ncua "classic".

Cov lus ceeb toom me me

Gas tuaj yeem compressed, tab sis cov kua tsis tuaj yeem compressed (tshwj tsis yog qhov siab heev, vim tias txhua yam yog compressed ... Txawm tias ib lub pob zeb diamond. Lub hnub qub neutron), yog li ib tus tsis tuaj yeem cia siab kom tau txais kev ncua raws li cov kua.

Lub ncua kev kawm ntawv muaj ib tug shock absorber (piston) thiab lub caij nplooj ntoos hlav, uas nyob rau hauv cov ntaub ntawv ntawm huab cua ncua kev kawm ntawv yuav tsum tau hloov nrog ib tug airbag. Lub caij nplooj ntoos hlav (los yog lub hauv ncoo) saib xyuas lub ncua ntawm lub tsheb nyob rau hauv cov huab cua, thaum lub shock absorber (piston) tswj lub ceev deflection (yog li ntawd tiv thaiv lub caij nplooj ntoos hlav los ntawm bouncing thaum xav tau kev pab, tab sis nws kuj tso cai rau lub ncua kev kawm ntawv los tswj.calibration. kom muaj zog los yog hloov tau). Yog li ntawd, nws slows down nyob rau hauv compression thiab rebound, li no lub npe ntawm lub shock absorber.

Qhov sib txawv ntawm active thiab semi-active ncua kev kawm ntawv

Thaum raug ncua nquagQhov kev ncua kev nruj tuaj yeem hloov pauv, tab sis peb kuj tuaj yeem kho qhov siab caij tsheb. Yog li, qhov kev ncua tuaj yeem tiv thaiv yob hauv ib lub ces kaum, tab sis nws tseem tuaj yeem nce qib yog tias koj dhau lub tsheb (tsis txhob muaj lub nraub qaum qis dhau, uas txhim kho kev sib npaug thiab yog li kev nyab xeeb). Hauv ntej, kev taw qhia (los ntawm cov khoom siv hluav taws xob) zoo meej!

Thaum raug ncua semi-active, tsuas yog qhov chaw damper hloov tau.

Nyob rau hauv ob qho tib si, lub ncua kev kawm ntawv yog tswj los ntawm ib tug hluav taws xob computer uas yuav tswj tau qhov qhib los yog txiav ntawm tej qhov chaw ntawm lub system, los yog txawm muaj feem xyuam rau cov hydraulic kua theem. Lub khoos phis tawj xav tau cov ntaub ntawv los ntawm ntau lub sensors los ua haujlwm (lawv zoo ib yam li nws lub qhov muag), xws li lub kauj lub kaum sab xis, lub tsheb nrawm, ncua kev mus ncig, thiab lwm yam. Hauv luv luv, tag nrho cov kev hloov pauv ntawm lub cev muaj txiaj ntsig zoo rau kev hloov pauv kev ncua. ... Yog tias ib qho ntawm cov sensors tsis ua haujlwm lawm, lub khoos phis tawj tsis muaj cov ntaub ntawv rau kev ncua kom ua haujlwm tau zoo (nws tsis tuaj yeem ua haujlwm dig muag).

Hydropneumatic ncua kev kawm ntawv (active suspension)

Cov kab ke no suav nrog lub voj voog hydraulic, tab sis qhov damping yog ua nrog roj: nitrogen. Nws yog Citroën uas tau tsim cov txheej txheem no ntawm cov lus dab neeg DS. Lub kaw lus tau txhim kho txij thaum ntawd los, tab sis lub hauv paus ntsiab lus tseem zoo li qub.

Thov nco ntsoov tias qhov layout tuaj yeem ua tau lwm yam, qhov no yog ib qho piv txwv. Cov spheres tej zaum yuav tsis yog ib qho nrog hydraulic damping, paub tias lwm tus tau muab tso rau hauv cov saw hlau kom tuaj yeem kho qhov kev ncua kev nruj (kev ua si hom).

1 : Nws yog ib daim nyias nyias uas cais cov kua los ntawm huab cua (ntau dua, los ntawm nitrogen).

2 : Qhov no yog sab saum toj ntawm qhov chaw uas muaj nitrogen nyob rau hauv siab. Nws yog nws uas hloov lub caij nplooj ntoos hlav ntawm ib tug pa shock absorber.

3 : qhov qis yog qhov yuav luag classic shock absorber piston, nws lub luag haujlwm yog txwv txoj kev tsav tsheb thiab yog li ntawd kom thaws lub tsheb ntawm pob.

Cov lus qhia ua haujlwm

Thaum peb thauj lub tsheb, qhov kev ncua yog crushed (nyob rau hauv peb rooj plaub, compressed cua). Lub twj tso kua mis hydraulic tuaj yeem coj cov kua dej los tsa lub luas (hauv av clearance) ntawm lub tsheb kom lub tsheb tsis qis dua.

Tsis tas li ntawd, rau hom kev nplij siab thiab kev ua si nawv kom muaj nyob, xav tau ntxiv spheres txuas nrog cov saw hlau (uas yog ib lub log ntxiv rau lwm qhov txuas nrog cov saw hlau). Thaum peb xav kom hnyav dua, peb rau txim rau qee qhov chaw. Qhov tseeb, qhov ntau spheres txuas nrog lub voj, ntau cov pa roj muaj rau damping thiab yog li hloov tau. Hauv qhov tseeb version ntawm Hydractive III, tsuas muaj 7 ntawm lawv.

Pros thiab cons

+ Kev nplij siab tshwj xeeb ua tsaug rau kev tshem tawm roj thiab, qhov tseem ceeb tshaj, kev tswj xyuas hluav taws xob (lub tsheb ib txwm nyob hauv kab rov tav). Lub Xantia Activa tau hloov pauv heev vim nws tau los ua tiaj tus hauv cov ces kaum (xav txog qhov tshaj tawm rau yav tom ntej nrog Carl Lewis).

+ Kev nplij siab txawm nyob rau hauv hom kev ua si nawv, kev ncua sij hawm tsuas yog tshwm sim thaum tsim nyog (qhov kev hloov pauv no tuaj yeem ua ob peb zaug ib ob ...). Nyob rau hauv ib lo lus, butter thiab nyiaj los ntawm butter!

+ Lub peev xwm los kho qhov siab caij tsheb (uas txhais tau tias nws tseem nyob tas li, txawm tias qhov hnyav ntawm lub nkoj)

+ Ntau hom kev tsav tsheb (kev nplij siab thiab kev ua kis las)

+ Kev coj tus cwj pwm nce ntxiv los ntawm kev txo suab thiab yob (qee zaum, muaj lub zog tiv thaiv yob, tswj hluav taws xob)

+ Kev tiv thaiv zoo rau lub sijhawm, vim tias nitrogen tsis hnav tawm piv rau cov springs

- Nqis thiab cumbersome system

- Nqis thaum nws los txog rau kev saib xyuas (vim tias daim nyias nyias thiab spheres nws thiaj li "zoo" tawg dhau sijhawm (150 txog 000 km raws li qee qhov)

- Ntawm qhov qub Hydractive, lub kaw lus txuas nrog lub zog tsav thiab nres. Thaum kawg, thaum muaj teeb meem, txhua yam tawm mus! Cov txheej txheem nyob sab Europe tau txwv txoj kev no txij li thaum.

Piv txwv li: Citroën Hydractive.

Nco ntsoov tias thaum lub C5 muaj hydropneumatic ncua kev kawm ntawv, C4 Picasso 1 muaj cua ncua (tsim hauv qab).

Cua ncua kev kawm ntawv (active suspension)

Cov txheej txheem no zoo ib yam li hydropneumatic, tab sis muaj cov ntsiab lus nrog huab cua xwb.

Kuj nyeem: hauv kev nthuav dav yuav ua li cas lub tshuab nqus tsev ua haujlwm.

Ntawm no, piv txwv siv lub rear ncua kev kawm ntawv ntawm lub C4 Picasso dua, lub shock absorber nyob rau hauv ib sab ntawm lub airbags (cov no yog kev koom ua ke rau hauv lub Mercedes Airmatic lub cev, tab sis lub hauv paus ntsiab lus tsis hloov). Nws tsis zoo ib yam ntawm lub qag pem hauv ntej uas muaj qhov chaw me me.

Thov nco ntsoov tias cov hauv ncoo tuaj yeem ua haujlwm nrog kev tswj xyuas kev cuam tshuam hauv qee kis. Ntawm no, cov no yog yooj yim shock absorbers, calibration uas tsis hloov.

Lub hauv ncoo cushions cuam tshuam thiab tshem tawm lub tsheb, thaum lub tsheb poob siab (piston) txwv cov nyhuv rov qab, pab kom txoj kev (nws tswj kev ceev). Nco ntsoov tias qhov kev npaj nram qab no kuj muaj rau cov kev ncua ntev, yog li lub caij nplooj ntoos hlav hloov lub airbag (peb feem ntau yog siv los pom lawv ua ib chav tsev, lub caij nplooj ntoos hlav ncig lub piston). Kuj tseem coj mus rau hauv tus account tias muaj lwm yam khoom siv uas tsis yog daim duab saum toj no, raws li pom nyob rau hauv qis Mercedes.

Ntawm no dua, cua yog siv, uas absorbs shocks, tab sis tsis zoo li hydropneumatics, huab cua yog txhaj los yog tshem tawm es tsis txhob ntawm cov kua. Yog li, peb kuj tuaj yeem hloov qhov chaw (stiffness) ntawm kev ncua, nrog rau lawv qhov siab (hauv av clearance).

Qhov zoo thiab qhov tsis zoo yog hais txog tib yam li rau hydropneumatics.

Piv txwv li: Mercedes Airmatic.

Khawv koob lub cev tswj (Mercedes) nrog Airmatic cua ncua

Nco ntsoov tias Mercedes tau tso rau pem hauv ntej "vice" (hauv S-Class) rau txoj hauv kev los soj ntsuam cov koob yees duab. Thaum lub khoos phis tawj kuaj pom pob, nws softens lub ncua kev kawm ntawv nyob rau hauv ib tug split thib ob ... Nws hu ua Magic lub cev Control.

Kev ncua kev ncua ntawv hauv pem teb active (tswj damping)

Nws yog txaus rau mechanically kho lub valve ntws nyob rau hauv lub piston kom lub damping. Hom valve no ces tswj hluav taws xob, tom qab uas ob peb damping adjustment yuav ua tau raws li txoj hauj lwm ntawm cov li qub. Qhov nrawm dua lawv dhau cov kua los ntawm ib qho chaw mus rau lwm qhov, lub softer lub ncua (thiab vice versa). Tom qab ntawd peb tuaj yeem tau txais kev nyiam los yog kev ua si nawv. Nco ntsoov tias qhov no yog txoj hauv kev zoo tshaj plaws kom tau txais kev ncua ib nrab thiab tias txoj cai no tsuas yog siv hauv Golf 7 DCC.

Nws yog hais txog kev tswj tsuas yog lub shock absorbers thiab tsis yog lub ncua kev kawm ntawv springs raws li nyob rau hauv cov huab cua ncua kev kawm ntawv. Tsis tas li ntawd, lub active huab cua ncua kev kawm ntawv kuj muaj kev tswj damping. Qhov no yog cov ntaub ntawv nrog Airmatic: airbags saib xyuas lub ncua kev kawm ntawv, thiab adjustable dampers saib xyuas damping (yog li lawv muaj peev xwm hloov nyob rau hauv cov nqe lus ntawm sizing, vim hais tias lawv yog adjustable).

Theoretical daim duab

Lub khoos phis tawj tswj cov solenoids sib txawv kom cuam tshuam rau qhov ntsuas. Qhov yooj yim dua lawv dhau cov roj, hloov tau yooj yim dua qhov damping, thiab vice versa ... Muaj ntau txoj hauv kev los ua qhov no, tshwj xeeb tshaj yog nrog kev pab ntawm cov hlau nplaum (Audi Magnetic Ride). Tsis tas li ntawd, qhov chaw qhia hauv daim duab tuaj yeem sib txawv kiag li hauv kev xyaum.

1: Cov kab txaij xiav me me yog li qub kom cov kua dej ntws nce thiab nqis (thaum lub slurry khiav). Ntawm cov pendants classic, lawv ib txwm ua haujlwm zoo ib yam. Ntawm no lawv tau tswj hwm los ntawm cov khoom siv hluav taws xob, uas tso cai rau koj hloov pauv qhov ua tau, tsim kom muaj kev ncua ntau dua lossis tsawg dua. Thov nco ntsoov tias ntawm no tsis yog cov pa roj (cua ncua kev kawm) uas saib xyuas kev ncua ntawm tag nrho, tab sis lub caij nplooj ntoos hlav, txhua yam yog ntau classic.

+ Ntau hom kev tsav tsheb (kev nplij siab thiab kev ua kis las)

+ Ntau tus cwj pwm los ntawm kev txo lub suab

+ Tsawg nqi thiab hnyav dua li kev ncua kev ua haujlwm

- Tsis nquag

- Tsis muaj peev xwm kho qhov siab caij tsheb

- Kev nplij siab qis dua ntawm lub log tsheb (lub caij nplooj ntoos hlav yuav zoo dua li lub cushion cua). Cov cwj pwm tsis tuaj yeem kho qhov zoo.

Piv txwv li: Audi Magnetic Ride

Electromagnetic ncua kev kawm ntawv (active suspension)

Ntawm no yog ib qho electromagnet uas tswj cov kev ncua nyob rau hauv tib txoj kev raws li nyob rau hauv lub suab hais lus. Kuv ceeb toom rau koj tias lub tshuab hluav taws xob yog cov hlau nplaum uas siv hluav taws xob, yog li peb tuaj yeem hloov lub zog ntawm cov hlau nplaum los ntawm kev kho lub zog ntawm qhov tam sim no. Paub tias cov hlau nplaum tuaj yeem sib tw, tsuas yog siv qhov chaw no los siv nws ua lub pendant. Bose tau tsim nws, thiab nws txoj kev siv tseem tsawg heev.
