Automatic transmissions uyetransaxlemasisitimu zvinhu zvakakosha zvemotokari dzemazuva ano, zvichipa kuve nyore kwekuchinja kusina musono uye kugovera kwesimba kwakanaka. Aya masisitimu anoumbwa neakawanda akaomarara zvikamu zvinoshanda pamwechete kuti ive nechokwadi chekushanda kwakanaka uye kwakavimbika. Muchinyorwa chino, tichaongorora zvikamu zvitatu zvikuru zveotomatiki transmission uye transaxle masisitimu, tichijekesa basa ravo uye kukosha kune yakazara mota kuita.
Torque converter:
Iyo torque inoshandura chinhu chakakosha cheiyo otomatiki transmission system. Inoita semusanganiswa wemvura inotamisa simba kubva muinjini kuenda kune kutapurirana, ichibvumira mota kuti isvike pakumira zvachose pasina kuita kuti injini imire. Iyo torque inoshandura ine zvikamu zvitatu zvikuru: impeller, turbine uye stator. Kana injini ichimhanya, impeller yakabatana nejini crankshaft inotenderera uye inogadzira kuyerera kwemvura yekufambisa. Mvura iyi inobva yanangidzirwa kune turbine yakabatana neiyo transmission input shaft. Sezvo mvura inoyerera kubva kune impeller ichienda kune turbine, inoita kuti turbine itenderere, ichiendesa simba kune kutapurirana.
Iyo stator iri pakati pe impeller uye turbine uye inoita basa rakakosha mukushandura mafambiro ekuyerera kwemvura kuwedzera torque kubuda. Iyi nzira inoita kuti mota ikurumidze kufamba zvakanaka uye zvakanaka. Uye zvakare, iyo torque inoshandura inopawo imwe huwandu hwekuwedzera torque, ichibvumira mota kuti itange nyore kubva pakumira. Pakazere, iyo torque inoshandura chikamu chakakosha cheiyo otomatiki yekufambisa sisitimu, kuve nechokwadi chekufambisa simba chisina musono uye kushanda kwakatsetseka panguva yekuchinja kwegiya.
Planetary gear set:
Iyo yepuraneti giya seti ndechimwe chinhu chakakosha cheotomatiki kutapurirana uye transaxle masisitimu. Iyo ine seti yemagiya anoshanda pamwechete kuti ape akasiyana mareshiyo ekutapurirana, achibvumira mota kuti ichinje magiya otomatiki. Iyo yepuraneti giya seti ine zvinhu zvitatu zvikuru: giya rezuva, magiya epasi, uye giya remhete. Izvi zvikamu zvakarongwa nenzira inovabvumira kudyidzana uye kugadzira akasiyana giya reshiyo, kusimudzira kukurumidza kukwirisa uye kufambiswa kwesimba kwakanaka.
Paunenge uchishanda, shaft yekupinza yekutapurirana yakabatana negiya rezuva, uye magiya epuraneti akaiswa pane inotakura nyika uye mesh negiya rezuva uye mhete giya. Sezvo shaft yekupinda ichitenderera, inotyaira giya rezuva, zvichiita kuti magiya epasi atenderere achiitenderedza. Kufamba uku kunodhiraivha giya remhete rakabatana neiyo transmission kubuda shaft. Nekuchinja kumhanya uye kwakanangana nekutenderera kwezvikamu izvi, seti yegiya repuraneti inogona kugadzira akasiyana giya reshiyo, ichibvumira mota kuti ichinje magiya zvisina musono kana ichimhanyisa kana kuderera.
Iyo yepuraneti giya seti inodzorwa neakatevedzana maclutches uye mabhendi anobata uye anoregedzera kusarudza yakakodzera giya reshiyo zvichienderana nekumhanya kwemotokari uye mutoro. Iyi yakaoma sisitimu yegiya uye maclutches inobvumira iyo otomatiki kutapurirana kuti ipe yakatsetseka, inoshanda yekufambisa simba iyo inosimudzira iyo yakazara yekutyaira ruzivo.
Hydraulic system:
Iyo hydraulic system chikamu chakakosha cheiyo otomatiki transmission uye transaxle system, ine basa rekudzora mashandiro emapuraneti magiya seti, torque converters uye zvimwe zvinhu. Inoshandisa kutapurirana mvura kuti iite zvikwata zvakasiyana-siyana, mabhanhire uye mavharuvhu, zvichibvumira kujeka, kuchinja panguva. MaHydraulic masisitimu ane network yemapombi, miviri yevharuvhu, uye nzira dzemvura dzinobatsira kugovera nekudzora kutapurirana kwemvura muhurongwa.
Iyo pombi inofambiswa neinjini uye ine basa rekugadzira hydraulic pressure mukati meiyo system. Iyi dzvinyiriro yakakosha pakubata clutch uye bhendi uye kudzora chinzvimbo chevhavha mukati memuviri wevharuvhu. Muviri wevharuvhu unoshanda senzvimbo yekudzora ye hydraulic system, inotungamira kufambisa kwemafuta kuyerera kune akakodzera maclutches uye mabhanhire anoenderana nekumhanya kwemotokari, mutoro uye mutyairi wekupinda.
Pamusoro pekudzora shanduko yegiya, iyo hydraulic system inoitawo basa rakakosha mukugadzirisa mashandiro eiyo torque inoshandura, kuve nechokwadi chekufambisa uye kusimba kwesimba pakati peinjini uye kutapurirana. Nekugadzirisa kuyerera kwekutapurirana fluid, iyo hydraulic system inogonesa iyo otomatiki kutapurirana kupa isina musono kuchinja uye kuita kwakaringana mumamiriro akasiyana ekutyaira.
Muchidimbu, otomatiki kutapurirana uye transaxle masisitimu ane akati wandei akakosha mazvikamu anoshanda pamwechete kuti ape isina musono shanduko uye inoshanda simba kugovera. Iyo torque inoshandura, yepuraneti giya seti uye hydraulic system zvinhu zvinoita basa rakakosha mukuita kwese kwekutapurirana. Kunzwisisa basa uye kukosha kwezvikamu izvi zvakakosha kuchengetedza uye kugadzirisa otomatiki transmission uye transaxle masisitimu uye kuona yakavimbika uye yakatsetseka kushanda kwemotokari.
