Momwe ma automatic transmission (BVA) amagwirira ntchito

Tsopano zofala ku France, mtundu uwu wa gearbox ulibe luso lomwelo luso monga kufala pamanja ndi magiya ofanana. Zowonadi, mabokosi amanja kapena a robotic (amakhala ofanana pang'ono) amakonzedwa mwanjira zosiyanasiyana. Sitikufuna clutch, mafoloko, kapena osewera ena pano. Ubwino wa ma transmissions odziwikiratu ndikuti safunikira kusokoneza / kusuntha pakati pa magiya.

Nawa mawonedwe ophulika amagetsi odziwikiratu, ndi chosinthira ma torque kumanzere ndi clutch / mabuleki ndi magiya kumanja.

Chikumbutso: Zithunzi zomwe zikuwonetsedwa apa ndi za Fiches-auto.fr. Kubwezeretsa kulikonse kumaphwanya ufulu wathu.

Onaninso: mavuto akuluakulu ndi kufala kwa basi.

Kusiyanitsa pakati pa torque converter ndi gearbox

Kwa odziwa pang'ono, muyenera kusiyanitsa pakati pa torque converter / clutch box kuti mupewe kusakaniza maburashi. Pa BVA (non-robotics), clutch imasinthidwa ndi chosinthira makokedwe kapena nthawi zina (kawirikawiri) makina owongolera.

Tikudziletsa pano ku gearbox osati makina ake ogwiritsira ntchito, kotero sindilankhula za chosinthira (onani apa kuti mudziwe zambiri).

Kuphatikiza apo, chosinthira makokedwe chimakhala ndi clutch yolambalala. Imayendetsedwa kuti ikhazikitse kulumikizana komveka bwino pakati pa injini ndi bokosi la gear (palibe kutsetsereka komwe kumalumikizidwa ndi chosinthira). Imayatsidwanso pakatentha kwambiri mafuta otumizira kuti asaphatikizepo chosinthiracho (ndipo chifukwa chake amawonjezera kutentha kwake).

Makina opangira zida zamagetsi

Dongosololi limathanso kutchedwa mapulaneti, chifukwa momwe moyo unayambira ndi wofanana ndi mapulaneti (njira). Mtengo woyambirira umayimira dzuwa ndipo mtengo wachiwiri umayimira mapulaneti ozungulira. Apa, mphamvu yochokera ku mota idzaperekedwa ndi zida za dzuwa (pachithunzi chakuda). Magiyawa amatha kutembenuza mwachangu gudumu la korona lolumikizidwa ndi mawilo, kutengera ngati magiya atsekedwa kapena ayi. Liwiro lirilonse lidzafanana ndi kutsekeka kwa magiya ena a mapulaneti.

Nawa mawonedwe ophulika a ma gearbox awiri a mapulaneti omwe ndidatha kuchita paziwonetsero zamagalimoto zapadziko lonse lapansi. Ili ndi bokosi lalikulu lopangidwira magalimoto ainjini aatali. Matembenuzidwe osinthika ndi ang'onoang'ono komanso ophatikizika (ayenera kuikidwa kumanzere [ngati ndikuyendetsa] pakati pa injini ndi mawilo).

Kusintha kwa zida?

Monga tanena kale, chiŵerengero cha magiya chimasintha kutengera ngati magiya ena a pulaneti atsekedwa (kenako msonkhanowo umayamba kusinthasintha mosiyanasiyana kutengera ngati njira imodzi yotereyi yatsekedwa). Kuti aletse ma satellites, kutumizira kumaphatikizapo mabuleki ndi ma clutches, magetsi kapena hydraulic oyendetsedwa ndi makompyuta (omwe amagwiritsira ntchito masensa ndi solenoids omwe amagwira ntchito ndi electromagnet: ma valve omwe amatsegula kapena kutseka kuti alole madzi amadzimadzi kuti adutse kapena ayi). Zinthu zomwe sizikuwonetsedwa muzithunzi zogwirira ntchito za magiya.

Ndizomwe zimayang'anira kusintha kwa gear ndi bypass clutch, chipangizo cha electro-hydraulic chomwe chimaphatikizapo ma valve solenoid (solenoids). Zachidziwikire, iyi ndi kompyuta yapadera yomwe imalumikizidwa ndikuyendetsa ma solenoids.

Apa tikuwona gawo la electro-hydraulic kudzera mu thupi lopangidwa mwapadera kuchokera kuwonekera. Bokosi (kumbuyo) ndi laling'ono kwambiri, chifukwa kwa magalimoto okhala ndi injini yodutsa. Kumanzere ndi belu la chosinthira makokedwe.

Kuthamanga kwa hydraulic ndipo motero kusalala kwa kusintha kwa gear) kumayendetsedwa ndi rerefaction ya mpweya yomwe imachokera pampu ya vacuum, yomwe imagwirizanitsidwa ndi aneroid capsule (pressure sensor), yomwe imalola kuti isinthe mogwirizana ndi katundu wa injini. (kuchuluka kapena kucheperako liwiro). Ndipotu, vacuum yopangidwa ndi mpope imadalira liwiro. Izi zimalola kuti pakhale maulendo osalala mosasamala kanthu za injini (popeza mawotchi ndi mabuleki sayenera kuchita chimodzimodzi malinga ndi magawo). Kompyutayo idzagwiritsa ntchito ma valves a solenoid control pressure malinga ndi zomwe zimatumizidwa ndi vacuum pump pressure sensor.

Ma valve odziwika bwino a solenoid / solenoids owongolera mabuleki amkati ndi ma tcheni.

Ma valve a solenoid amalumikizidwa ndikuyendetsedwa kudzera mu mbale yokhala ndi mapulagi oyendetsa.

Onaninso kuti kufala kwamtunduwu ndikosavuta komanso mwachangu kumaliza kuposa kutumizirana magiya ofanana. M'malo mwake, pakutumiza kwamanja, muyenera kusiya zida (chida chotsetsereka chomwe chimalekanitsa) ndikuphatikizanso china chatsopano, chomwe chimatenga nthawi ... Mu bokosi la pulaneti, ndikwanira kutseka kapena kutsegula magiya. ndi mabuleki ndi mabuleki (kwenikweni mabuleki ndi zotengera ndizofanana, zimangosintha ntchito), zoyendetsedwa ndi ma actuators omwe amagwira ntchito mwachangu.

Chifukwa chake, muyenera kudziwa kuti chosinthiracho chimangoyimitsa, kuti chisayime, ndikuti bokosilo limayang'aniridwa palokha, popanda kukhudza chosinthira (mosiyana ndi makina, palibe chifukwa cholekanitsira injini ku gearbox posintha magiya kapena kutsika).

Chifukwa chake, ma BVA ndi midadada yomwe sipereka nthawi yopumira kuti mupereke lipoti.

Pa kanema?

Thomas Schwencke wasindikiza kanema wowonetsa kwambiri pamutuwu, ndikupangira kuti muwonere:
