Intangiriro kubwoko bwa Automobile Chassis Bushings n'imikorere yabo ya NVH

Subframe Bushing, Bushing umubiri (Guhagarika)

1. Yashyizwe hagati ya subframe numubiri kugirango ikine uruhare rwa kabiri rwo kunyeganyega, mubisanzwe bikoreshwa muri horizontal powertrain;

2.Gushyigikira imizigo ihagarikwa hamwe na powertrain imizigo ishyigikira imizigo ihagarikwa na powertrain, gutandukanya ibinyeganyega n urusaku biva muri subframe Isolating vibrasiya n urusaku biva muri subframe;

3.Imirimo ifasha: ihangane na powertrain torque, powertrain ihagaze neza, ihangane na steering, imizigo yo guhagarika, moteri ya moteri hamwe nibyishimo byo mumuhanda

Igishushanyo mbonera

1.Ubwiherero bwinshyi cyangwa imbaraga zikomeye, coefficient de damping

2.Umutwaro uhagaze kandi uringaniye Umuzigo uhagaze kandi uringaniye, Kugabanya Ibisabwa byo Guhindura Ibisabwa Byanyuma

3.Umutwaro udasanzwe (gukoresha bisanzwe), umutwaro ntarengwa (ibintu bikomeye)

4.Ibisabwa byo guhura, imbogamizi n'imizigo, imbogamizi z'umwanya, ibyifuzo byateganijwe kandi bisabwa;

5.Uburyo bwo kubara (harimo ingano ya bolt, ubwoko, icyerekezo hamwe nibisabwa kurwanya anti-rotation, nibindi)

6.Umwanya wo guhagarikwa (ahantu hinjira cyane, utumva);

7.Ibisabwa byo kurwanya ruswa, ubushyuhe bwo gukoresha, ibindi bisabwa imiti, nibindi.;

8.Umunaniro ukenewe mubuzima, bizwi byingenzi bisabwa biranga (ibipimo n'imikorere);

9.Ibiciro

Uburyo bwo guterana

1.Kuruhande igice ni umutwaro utwara imizigo

2.Igice cyo hepfo ni Rebound padding

3.Umuringa wo hejuru Hejuru: * Shyigikira Kwagura Imizigo Yagutse * Kugenzura uburebure bw'Inteko:

1.

2) Padiri yo hepfo igenzura umubiri Gusubira inyuma;

3) Padiri yo hepfo ihora munsi yigitutu Icya kabiri, subframe bushing, umubiri bushing (guhagarikwa)

Guhagarika bushing

Gusaba:

1.Yakoreshejwe muri sisitemu yo guhagarika kugirango itange ihindagurika kandi ihindagurika, no kugenzura kwimura axial na radial;

2.Kureka gukomera kwa axial kubwo kwinyeganyeza kwiza mugihe byoroshye radial gukomera kugirango bihamye neza;

(1) Ubwoko bwubwubatsi: Amashanyarazi ahujwe na Bushings

- Porogaramu: Amababi yamababi, Shock Absorber Bushings, Inkoni ihamye;

- Ibyiza: bihendutse, ntukeneye kwitondera ikibazo cyo guhuza imbaraga;

- Ibibi: icyerekezo cya axial kiroroshye gusohoka, kandi gukomera biragoye kubihindura.

(2) Ubwoko bwubwubatsi: Uruhande rumwe rwahujwe na Bushings

Gusaba: Shock absorber bushings, inkoni zo guhagarika no kugenzura amaboko

- Ibyiza: Ntibihendutse ugereranije nibisanzwe bibiri-bifatanye guhuza ibihuru, ibihuru burigihe bizunguruka kumwanya utabogamye

- Ibibi: Icyerekezo cya axial kiroroshye gusohoka.Kugirango umenye imbaraga zikanda, ugomba kugira flash igishushanyo

(3) Ubwoko bwubwubatsi: Double Side Bonded Bushing

Gusaba: Shock absorber bushings, inkoni zo guhagarika no kugenzura amaboko

- Ibyiza: imikorere yumunaniro mwiza ugereranije no guhuza uruhande rumwe no guhuza imashini, kandi gukomera biroroshye guhinduka;

- Ibibi: Ariko igiciro nacyo gihenze kuruta guhuza uruhande rumwe no guhuza impande zombi.

:

Gushyira mu bikorwa: Kugenzura amaboko, gukurikira amaboko

- Inyungu: gukomera biroroshye guhinduka

- Ibibi: Uburyo bwo gutsindwa bwa orifice munsi yimbaraga za torsional (> +/- 15 deg);gushakisha ibintu bisabwa kugirango igitutu gikwiranye, bizongera amafaranga

:

Gusaba: ukuboko kugenzura;

- Ibyiza: ubukonje buke bwa cone, ubukonje buke bwa cone hamwe na radiyo nini;binini bya radiyo;

- Ibibi: Birahenze ugereranije nibisanzwe byombi-bihujwe na bushing

;

Gusaba: ukuboko kugenzura;

–Ibyiza: Ikigereranyo cya radial hamwe no gukomera kwa axial kirashobora kwiyongera kuva 5-10: 1 kugeza 15-20: 1, icyifuzo cya radial gishobora gukenerwa no gukomera kwa reberi yo hasi, kandi gukomera kwa torsional nabyo birashobora kugenzurwa;

- Ibibi: Ugereranije nibisanzwe byombi bifatanye guhuza ibihuru, birahenze, kandi iyo diameter igabanutse, imihangayiko ikaze hagati yigitereko cyimbere hamwe nicyapa cyo kugorora ntishobora kurekurwa, bikavamo ibibazo byimbaraga zumunaniro.

Stabilizer bar bushing

Akabari keza:

1. Mu rwego rwo guhagarikwa, umurongo wa stabilisateur utanga ubukana bwa torsional mugihe imodoka ihindutse cyane kugirango wirinde kwinuba gukabije kwimodoka;

2. Impera zombi z'umurongo wa stabilisateur zahujwe no guhagarikwa binyuze mu nkoni ya stabilisateur ya kabili (nk'ukuboko kugenzura) ihujwe;

3. Mugihe kimwe, igice cyo hagati gihujwe kumurongo hamwe na rubber bushing kugirango ituze

Igikorwa cya bushing

1. Imikorere ya stabilisateur bar bushing nkibikoresho bihuza inkoni ya stabilisateur hamwe na kadamu;

2. Itanga izindi torsional stiffness kuri stabilisateur bar inkoni;

3. Igihe kimwe, irinda kwimuka mu cyerekezo cya axial;

4. Ubushyuhe buke Urusaku rudasanzwe rugomba kwirindwa.

Bushing zitandukanye

Igikorwa cyo gutandukanya bushing

Kuri moteri yimodoka enye, itandukaniro muri rusange ihujwe numubiri binyuze mu gihuru kugirango igabanye guhindagurika

Intego za sisitemu:

20 ~ 1000Hz igipimo cyo kwigunga
uburyo bukomeye bwumubiri (Roll, Bounce, Pitch)
kugenzura kubera ubushyuhe Ihindagurika rikomeye ryatewe nimpinduka

Hydraulic bushing

Ihame ry'imiterere:

1. Mu cyerekezo cya hydraulic damping, ibyumba bibiri byamazi byuzuyemo amazi bihujwe numuyoboro muremure ugereranije kandi muto (bita umuyoboro udasanzwe);

2. Mugihe cyo kwishima mucyerekezo cya hydraulic, amazi azongera kumvikana kandi gukomera kwijwi bizongerwaho, bivamo agaciro keza cyane.

Gusaba:

1. Kugenzura icyerekezo cya radiyo yo kumanika amaboko;

2. Icyerekezo cyo kumanika icyerekezo cyo gukurura inkoni;icyerekezo cya axial icyerekezo cyo gukurura inkoni;

3. Kugenzura amaboko ya radiyo yerekana icyerekezo ariko gushiraho vertical;

4. Subframe bushing yamanitswe mu cyerekezo cya radiyo ariko igashyirwa mu buryo buhagaritse busframe bushing yamanitswe mu cyerekezo cya radiyo ariko igashyirwaho ihagaritse

5. Igiti cya torsion gishyirwaho muburyo butagaragara bwa radiyo;

6. Gushyigikirwa ku nkingi, yashyizwe mu buryo buhagaritse mu cyerekezo cya damping

7. Komeza umunezero wa Judder uterwa nimbaraga zitaringaniye za feri yimbere

8. Ongera uhindure uburyo bwa vibrasiya ya radial na kuruhande ya subframe, kandi icyerekezo cyo kumanura nicyerekezo cya radiyo.

9. Inyuma ya torsion beam hydraulic bushing ikoreshwa muguhagarika umunezero mugihe ikinyabiziga kigenda mumihanda igoye, mugihe gikosora amano.

10. Hydraulic strut ishyigikiwe kuruhande rwo hejuru, ikoreshwa mugucunga uburyo bwa 10 ~ 17Hz Hop yumuziga, kandi ibiranga imbaraga zayo ntibigenga kumashanyarazi.
