Mitsamiro ya atatu, kapena momwe injini za 3-silinda zimayikidwa

Opanga magalimoto akuchulukirachulukira kubweretsa injini zamasilinda atatu muzopereka zawo. Ngakhale mayunitsiwa amadya mafuta ochepa poyerekeza ndi ma cylinder anayi, komano, amayambitsa zovuta zingapo zomwe zimagwirizanitsidwa makamaka ndi kukwera kwawo pamafelemu agalimoto.

Kodi vuto ndi chiyani?

Chiwerengero chochepa cha masilindala chimafuna kugwiritsa ntchito njira zoyenera zochepetsera, kuphatikiza ma shafts owerengera. Mapiritsi opindika amayenera kusinthidwa kuti agwirizane ndi kapangidwe kake, mosiyana ndi injini zamasilinda anayi. Pofuna kuonetsetsa kuti kugwedezeka koyenera kwa mayunitsi a silinda atatu, makina okwera oyenerera amagwiritsidwa ntchito, omwe amalepheretsa, makamaka, kayendedwe kawo kotalika komanso kodutsa.

Hydraulic, electro-hydraulic kapena torque fasting?

Kuyika injini zamasilinda atatu, ma cushions a hydraulic ndi electro-hydraulic angagwiritsidwe ntchito, omwe amakhala ndi moyo wautali wautumiki. Komabe, masiku ano zomwe zimatchedwa "brake mount" zolumikizira zimadziwika kuti lollipops. Mu yankho ili, kugwetsa kugwedezeka kumaperekedwa ndi cholumikizira chapadera, momwe bushing imodzi imamangiriridwa ku injini, ndipo ina imangiriridwa ndi thupi. Ubwino wa "torque support" cushions ndikuchepetsa kokhazikika kwa injini yopendekera, ndipo kuipa kwake ndi moyo wamfupi wautumiki poyerekeza ndi ma cushions a hydraulic.

Kusweka ndi chiyani?

Manja okwera amawonongeka mwamakina panthawi yogwira ntchito. Kulephera kwa mmodzi wa iwo kumabweretsa mokweza injini ntchito, komanso kugwedera (resonant kugwedera) opatsirana ku galimoto thupi. Kuyendetsa galimoto kwa nthawi yayitali yokhala ndi chiwongolero chosokonekera kutha kuwononga zida zotumizira ndikupangitsa kugwedezeka kowoneka bwino mu lever yosuntha ndi chiwongolero. Zikafika poipa, kusowa dampening wa kugwedera kumabweretsa kuwonongeka kwa chiwongolero, injini ndi kufala.

Ndi nthawi yoti mulowe m'malo?

Palibe mtunda wokhazikika pambuyo pake ma airbags okwera injini ayenera kusinthidwa. Ayenera kusinthidwa ndi atsopano pamene zizindikiro zowonongeka zikuwonekera. Chenjerani! Ngati pad yowonongeka imayikidwa axially ndi pedi ina (mwachitsanzo, pakati pa malo otsekemera a injini), zonsezi ziyenera kusinthidwa.

Ndi ma variable damping makhalidwe

Mu njira zamakono, otchedwa yogwira injini amakwera, yodziwika ndi variable damping makhalidwe. Njira imodzi ndiyo kugwiritsa ntchito ma electromechanical drive. Zimakuthandizani kuti musinthe kuchuluka kwa momwe mumayendetsedwera panopa kapena njira yoyendetsera yosankhidwa ndi wogwiritsa ntchito, komanso kuwongolera bwino njira yosinthira kugwedezeka kwamphamvu (izi ndizofunikira makamaka pakakhala ma silinda atatu pamzere. injini).

Chosiyana ndi njirayi ndi chokwera chamoto chokhala ndi njira ziwiri zogwirira ntchito (m'malo moyendetsa magetsi). Zomwe zimatchedwa zofewa za khushoni zimamveka pokhapokha ngati zikugwira ntchito. Momwemonso, pakuyenda kwa galimoto, kukula kwa mphamvu yowonongeka kumasinthasintha ndipo kumagwirizana ndi ma oscillation amakono a injini.

Kodi damping yabwino imasankhidwa bwanji? Kugwira ntchito kwa khushoni ya injini kumayendetsedwa ndi gawo lowongolera, lomwe limalandira zidziwitso kuchokera ku magwero awiri: sensor yothamanga ya crankshaft ndi masensa mathamangitsidwe (omwe ali pazigawo ziwiri za injini). Amapereka zenizeni zenizeni zenizeni zenizeni kuti athetse kugwedezeka. Njira ina yochepetsera kugwedezeka ndi kugwiritsa ntchito makina apadera a hydraulic mu makina oyimitsidwa a injini. Amatsitsimutsidwa ndi sing'anga ya hydraulic (hydraulic fluid yochokera ku propylene glycol), yomwe pakadali pano ndi misa yamkati yomwe imalinganiza kugwedezeka. Zimagwira ntchito bwanji? Mayamwidwe amphamvu-amplitude kugwedera mphamvu kuchokera kuyimitsidwa chinthu kumachitika chifukwa cha kutuluka kwa madzimadzi ogwirira ntchito kuchokera kuchipinda chogwirira ntchito (kudzera munjira zonyowa) kulowa muchipinda chofananira. Kuthamanga uku kumapangitsa kugwedezeka kosafunikira komanso kumachepetsanso kusuntha kwautali ndi kozungulira kwa injini. Kumbali ina, ndi matalikidwe ang'onoang'ono a oscillation, damping imatheka ndi chisindikizo chapadera choyandama cha diaphragm. Zimagwira ntchito bwanji? Chisindikizo cha diaphragm chimagwedezeka, mosiyana ndi kugwedezeka kopangidwa ndi injini. Chifukwa chake, kugwedezeka kosafunika komwe kumatumizidwa ku thupi kumakhala kochepa, kotero palibe chifukwa chogwiritsira ntchito ma shaft owonjezera.
