Isixhumi se-trailer siyingxenye eyinhloko yezinhlelo zesimanje zokudonsa izimoto. Umsebenzi wayo ukusungula ukuxhumana kukagesi, isignali, nokomshini phakathi kwemoto edonsayo ne-trailer, iqinisekisa ukuphepha nokusebenza kwe-trailer ngesikhathi sokushayela. Ngokuthuthuka kwemboni yezimoto, idizayini yesixhumi se-trailer nobuchwepheshe buguquka njalo ukuze buhlangabezane nezidingo zezimo ezahlukahlukene.
Ngokwesakhiwo, isixhumi se-trailer ngokuvamile sihlanganisa ukuxhunywa kukagesi kanye nendlela yokukhiya eyimishini. Uxhumano lukagesi ludlulisela amasignali afana namalambu amabhuleki, amasignali ajikajikayo, namalambu ahlehlayo, kanye nokunikeza amandla kusilawuli samabhuleki se-trailer kanye nesistimu ye-ABS. Izindinganiso ezivamile zesixhumi sikagesi zihlanganisa izixhumi ezingu-7-pin nezi-4-pin ezisetshenziswa eNyakatho Melika, kanye nesixhumi se-ISO samaphini angu-13 esisetshenziswa kabanzi eYurophu. Uxhumano lwemishini luqinisekisa ukuxhumana okuphephile phakathi kwe-trailer nemoto edonsayo, kuvimbela ukunqanyulwa kwengozi phakathi nokushayela. Ivamise ukusebenzisa isikhiya sebhola noma idizayini ye-coupler.
Ukusebenza kwesixhumi se-trailer kuthinta ngokuqondile ukuphepha kokushayela. -Izinga eliphansi noma izixhumi ezindala zingaholela ekudluliselweni kwesignali okungazinzile futhi kwandise ingozi yezingozi zomgwaqo. Ngakho-ke, kubalulekile ukuhlola njalo izindawo zokuxhumana zesixhumi ukuze uthole i-oxidation kanye nendlela yokukhiya ukuze kusebenze kahle. Ngaphezu kwalokho, amazinga okuxhuma ama-trailer ayahluka emazweni nezifunda, okwenza kudingeke ukuthi kusetshenziswe ama-adaptha noma izixhumi ezishintshayo ezithobelana nemithetho yendawo yezokuthutha zamazwe ngamazwe.
Ngokuthuthuka kobuchwepheshe obuhlakaniphile, isizukulwane esisha sezixhumi ze-smart trailer sesiqalile ukuhlanganisa izinzwa namandla okudlulisa idatha, okuvumela{0}}ukuqapha kwesikhathi sangempela kwesimo se-trailer, njengokucindezela kwesondo kanye nempilo yesistimu yamabhuleki, okuqhubekisela phambili ukuthuthukisa ukuphepha kokushayela. Ngokuzayo, izixhumi zama-trailer zizothuthukela ekusebenzeni kahle kakhulu nasekuthembekeni, zinikeze izixazululo zokudonsa ezithuthukisiwe zemikhumbi yezentengiselwano nabasebenzisi abazimele.
