I-Crossmember ibizwa nangokuthi i-sub-frame, ebhekisela ekusekelweni okusekela ama-axles angaphambili nangemuva kanye nokumiswa ukuze ibhuloho nokumiswa kuxhunywe "ku-mainframe" ngayo. Ngemuva kokufakwa, ingavimba ukudlidliza nomsindo futhi inciphise ukungena kwayo ngqo enqoleni. umsindo we.

Ngokuvamile, i-crossmember idinga ukuqina okuphezulu ngokwesakhiwo. Iphedi yerabha ingangezwa phakathi kwe-mainframe kanye ne-crossmember. Uma uhlaka oluyinhloko lukhubazekile, irabha enwebekayo iyawohloka ukuze yenze buthaka ukubamba kwe-crossmember kuhlaka oluyinhloko. Naka i-crossmember. Lapho i-crossmember ihlelwe ku-chassis yemoto, ukuphela kwayo kufanele kube eduze ngangokunokwenzeka odongeni olungemuva lwekhabhi.

Umhlangano we-A-frame crossmember uhlanganisa i-crossmember kanye nobakaki wokuxhuma. Ibakaki elixhumayo linendawo engaphezulu nendawo eseceleni. Indawo engaphezulu yebakaki yokuxhuma ixhunywe ngezansi kwephuzu elisekela le-crossmember, futhi indawo eseceleni yebakaki yokuxhuma ixhunywe endaweni yophiko oluseceleni lwesigxobo se-longitudinal yefreyimu Ngaphakathi. Ubakaki oxhumanisayo uhlelwe endaweni eseceleni yephiko le-frame longitudinal beam ukuze kugwenywe indawo engaphezulu yephiko le-longitudinal beam enokucindezeleka okuphezulu kakhulu, ngaleyo ndlela kugwenywe inkinga yokuqhekeka kwembobo e-riveting okubangelwa ukugxila kokucindezeleka, futhi kuthuthukise kakhulu ukuphepha imoto
