mayendedwe oyima poyendetsa, ndipo zotanuka mumayendedwe oyimitsidwa zimanjenjemera momwe zimakhudzidwa.Chifukwa chake, ndikofunikira kuyika zotsekemera zotsekemera mofananira ndi zinthu zotanuka pakuyimitsidwa kuti muchepetse kugwedezeka ndikuwongolera kuyenda bwino kwagalimoto.
Ma hydraulic shock absorber nthawi zambiri amagwiritsidwa ntchito pamayimidwe amagalimoto.Mfundo yake yogwirira ntchito ndi yakuti pamene chimango kapena thupi ndi exle zikuyenda pang'onopang'ono chifukwa cha kugwedezeka, pisitoni yomwe ili muzitsulo zotsekemera imasunthira mmwamba ndi pansi, ndipo mafuta omwe ali muzitsulo zogwedeza amayenda kuchokera ku khola limodzi kupita ku lina mobwerezabwereza kupyolera mu zosiyana. mipata.Panthawiyi, kukangana pakati pa khoma la dzenje ndi mafuta ndi kukangana kwamkati pakati pa mamolekyu a mafuta kumawononga mphamvu yogwedezeka, ndikupanga mphamvu yowonongeka pa kugwedezeka, kotero kuti mphamvu yogwedeza galimotoyo imasandulika kukhala mphamvu ya kutentha kwa mafuta, kenaka kutengeka ndi chotsitsa chodzidzimutsa ndikugawidwa kumlengalenga.Zinthu monga mayendedwe amtundu wamafuta zimakhalabe zosasinthika, mphamvu yonyowa imasintha ndikuwonjezeka kapena kutsika kwa liwiro loyenda pakati pa chimango ndi ekisi, ndipo imagwirizana ndi kuchuluka ndi kukula kwa mabowo akukhuthala kwamafuta.
Ma Elastic Elements ndi ma shock absorbers ndi omwe amachititsa kuti buffering ndi damping.Ngati damping mphamvu ndi yaikulu kwambiri, kugwedera attenuation amakhala mofulumira kwambiri, zomwe zimapangitsa kuti buffering wa zinthu zotanuka kuyimitsidwa kuipiraipira, ndipo ngakhale kuwononga shock absorber zolumikizira ndi chimango.Kawirikawiri, galimotoyo ikhoza kukhala m'madera atatu panthawi yoyendetsa;Yoyamba ndikuyendetsa pamsewu wabwino, pomwe zinthu zotanuka zimafunikira kuti zigwire ntchito yonse;Chachiwiri ndi chakuti chowombera chodzidzimutsa chimakhala ndi gawo lotsogolera pamene galimotoyo imakhala ndi kugwedezeka kwapakati;Mlandu wachitatu ndi wakuti galimotoyo imagwedezeka kwambiri, yomwe imagwirizana kwambiri ndi matayala.Kuti mugwire ntchito mogwirizana ndi zinthu zotanuka pansi pamikhalidwe itatu yomwe ili pamwambapa, chotsitsa chododometsa chiyenera kukwaniritsa izi:
(1) Panthawi ya kuyimitsidwa kwapang'onopang'ono (chiwombankhanga ndi chimango zili pafupi wina ndi mzake), mphamvu yochepetsetsa ya choyimitsa chododometsa ndi yaying'ono, kuti iwonetsetse kwathunthu gawo lotanuka la zinthu zotanuka ndikuchepetsa mphamvu.Panthawiyi, chinthu chotanuka chimakhala ndi gawo lalikulu;
(2) Pa kuyimitsidwa kutambasula sitiroko (chiwongolero ndi chimango ali kutali wina ndi mzake), damping mphamvu ya shock absorber ayenera kukhala lalikulu kuchepetsa kugwedera mofulumira.Panthawiyi, chotsitsa chododometsa chimagwira ntchito yaikulu;
(3) Pamene kuthamanga kwachibale pakati pa chimango kapena thupi ndi nkhwangwa ndipamwamba kwambiri, chowombera chodzidzimutsa chimayenera kuonjezera kutuluka kwamadzimadzi momasuka kuti chiwonongeko chikhale mkati mwa malire ena, kuti tipewe chimango kapena thupi. kukhudza kwambiri katundu.
The hydraulic shock absorber yomwe imagwiritsidwa ntchito kwambiri pamakina oyimitsa magalimoto ndi cylindrical shock absorber, yomwe imatchedwanso kuti njira ziwiri zowonongeka chifukwa zimatha kuchepetsa kugwedezeka muzitsulo zonse zoponderezedwa ndi zowonjezera.
Mfundo ntchito ya njira ziwiri kuchita mantha absorber.Silinda yakunja yachitsulo ndi chivundikiro cha fumbi, ndipo kumtunda kumalumikizidwa ndi chimango (thupi) ndi mphete.Silinda yachitsulo pakati ndi malo osungiramo mafuta, okhala ndi kuchuluka kwa mafuta otsekemera mkati, ndipo mphete yomwe ili m'munsiyi imalumikizidwa ndi chitsulo.Silinda yachitsulo yamkati ndi silinda yogwira ntchito yodzaza ndi mafuta owopsa.M'kati mwa silinda yogwira ntchito, ndodo ya pistoni, yomwe imagwirizanitsidwa ndi chivundikiro cha fumbi ndi mphete yapamwamba, imagwiritsidwa ntchito kukonza pisitoni kumapeto kwake.Pistoni ili ndi valavu yowonjezera ndi valve yothamanga, ndipo m'munsi mwa silinda yogwira ntchito imakhala ndi valavu yopondereza ndi valavu yolipira.Pofuna kupangitsa kuti phokoso likhale lopweteka kuti likwaniritse zofunikira zogwirira ntchito, akasupe a valve otaya ndi valve yamalipiro ndi ofewa, ndipo mafuta ochepa amatha kutsegulidwa kapena kutsekedwa.Akasupe a valve compression ndi valve yowonjezera ndizovuta kwambiri, ndipo amatha kutsegulidwa kokha pamene kuthamanga kwa mafuta kumawonjezeka pamlingo wina;Malingana ngati mafuta akutsika pang'ono, valavu idzatsekedwa nthawi yomweyo
Njira yogwiritsira ntchito njira ziwiri zogwiritsira ntchito cylinder shock absorber ndi motere: pamene sitiroko ikukanikizidwa, chotsitsa chogwedeza chikanikizidwa, mawilo a galimoto amasunthira pafupi ndi thupi, pisitoni muzitsulo zogwedeza zimayenda pansi, voliyumu ya Chipinda chochepa chimachepa, ndipo kuthamanga kwa mafuta kumawonjezeka.Mafuta ambiri amalowa m'chipinda cham'mwamba atathamangitsira valve yothamanga.Popeza chipinda cham'mwamba chimakhala ndi ndodo ya pisitoni, kuchuluka kwa chipinda cham'mwamba kumakhala kocheperako kuposa kutsika kwa chipinda cham'munsi, kotero kuti gawo lina la mafuta limabwereranso kumalo osungiramo mafuta pokankhira valve compression.Mafuta akadutsa mu dzenje la valve, chotsitsa chogwedeza chimatambasulidwa ndipo magudumu amakhala kutali ndi thupi.Panthawiyi, pisitoni ya chowotcha chododometsa imakwera m'mwamba, kuthamanga kwa mafuta m'chipinda chapamwamba kumakwera, valavu yothamanga imatsekedwa, ndipo valavu yotsegulira mafuta a hydraulic m'chipinda chapamwamba imalowa m'chipinda chapansi.Chifukwa cha kukhalapo kwa ndodo ya pisitoni, mafuta otuluka kuchokera kuchipinda chapamwamba sangakwanire kudzaza njira yowonjezera yowonjezera m'chipinda chapansi, zomwe zimapangitsa kuti chipinda chapansi chitulutse mpweya wina.Panthawiyi, mafuta omwe ali m'malo osungiramo mafuta amakankhira valavu yamalipiro ndikulowa m'chipinda chapansi kuti awonjezere.Kugwedezeka kwa ma valve awa kumakhala ndi zotsatira zowonongeka pa kuyimitsidwa panthawi yotambasula.
Monga kuuma kwa kasupe ndi mphamvu ya pretension ya valve yotambasula idapangidwa kuti ikhale yayikulu kuposa ya valavu yopondereza, pansi pa mphamvu yomweyo, gawo lonse la valavu yotambasula ndi njira yofananira yofananira ndi yocheperako kuposa malo onse onyamula. wa valavu psinjika ndi lolingana yachibadwa kusiyana njira, zomwe zimapangitsa damping mphamvu kwaiye anatambasula sitiroko ya mantha absorber kuposa mphamvu damping kwaiye psinjika sitiroko, kuti akwaniritse zofunika kuchepetsa kugwedera mofulumira.
Kuphatikiza apo, makina oyimitsidwa amitundu ina amagwiritsa ntchito ma inflatable shock absorbers, chosinthira damping force shock absorbers ndi inflatable shock absorbers.Pansi pa mbiya ya silinda ya chotsitsa chodzidzimutsa imakhala ndi pisitoni yoyandama, ndipo chipinda chotsekedwa cha mpweya chimapangidwa pakati pa pisitoni yoyandama ndi malekezero a mbiya ya silinda, yokhala ndi nayitrogeni wothamanga kwambiri mkati.Pistoni yoyandama (pistoni yosindikiza gasi) imakutidwa ndi mafuta, ndipo pisitoni ili ndi gawo lalikulu la O-ring, lomwe limagwiritsidwa ntchito kulekanitsa kwathunthu mafuta ndi gasi.Kuthamanga kwa pisitoni yogwira ntchito kumasintha, zomwe zimapangitsa kuti pakhale mphamvu zosiyanasiyana.Ma valve otambasula onse ndi valavu yoponderezedwa amapangidwa ndi gulu la mapepala achitsulo a masika omwe ali ndi makulidwe ofanana ndi ma diameter osiyana omwe amakonzedwa kuchokera ku zazikulu mpaka zazing'ono.
Poyerekeza ndi njira ziwiri zochitira ma cylinder shock absorber, cholumikizira chotenthetsera mpweya chimakhala ndi izi:
(1) Pistoni yoyandama imachepetsa dongosolo la mavavu, kufewetsa kapangidwe kake ndikuchepetsa kulemera.
(2) Pamene chotsitsa chododometsa chimadzazidwa ndi nayitrogeni wothamanga kwambiri, chimatha kuchepetsa kugwedezeka kwa gudumu modzidzimutsa ndikuchotsa phokoso.
(3) Monga silinda yogwira ntchito ndi pisitoni m'mimba mwake ya mpweya wodzazidwa ndi mpweya ndi zazikulu kuposa za njira ziwiri zogwiritsira ntchito cylinder shock absorber pansi pamikhalidwe yomweyi, kusungunuka kwake kumakhala kwakukulu ndipo kudalirika kwake kogwira ntchito kumakhala kolimba.
(4) Mpweya wothamanga kwambiri ndi mafuta mu mpweya wotsekemera wa pneumatic amasiyanitsidwa ndi pisitoni yoyandama, yomwe imathetsa emulsification ya mafuta.
Kuipa kwa chotsitsa mpweya wodzaza ndi gasi ndikuti chimakhala ndi zosindikizira zambiri zamafuta, njira zovuta zodzaza gasi, ndipo ndizovuta kuzisamalira.Silinda ya silinda ikasinthidwa chifukwa cha kukhudzidwa kwakukulu kwakunja, sikungagwire ntchito.
