Crossmember nanone yitwa sub-frame, bivuga inkunga ishyigikira imitambiko yimbere ninyuma no guhagarikwa kugirango ikiraro nuguhagarikwa bihuzwa na "mainframe" binyuze muri yo. Nyuma yo kwishyiriraho, irashobora guhagarika kunyeganyega n urusaku no kugabanya iyinjira ryayo muri gare. ijwi rya.

Muri rusange, kwambuka bisaba gukomera cyane mubijyanye nimiterere. Ibikoresho bya reberi birashobora kongerwaho hagati yingenzi na crossmember. Iyo ibice nyamukuru byahinduwe, reberi ya elastike ihindurwa kugirango igabanye kwambuka kwambukiranya imipaka. Witondere kwambuka. Iyo crossmember itunganijwe kuri chassis yimodoka, impera yimbere igomba kuba yegeranye bishoboka kurukuta rwinyuma rwakabari.

A-ikadiri yambukiranya inteko ikubiyemo umusaraba hamwe nu murongo uhuza. Ihuza rito rifite ubuso bwo hejuru hamwe nubuso bwuruhande. Ubuso bwo hejuru bwibice bihuza bihujwe munsi yingoboka ya crossmember, naho uruhande rwuruhande rwumutwe uhuza uhujwe nububaba bwibaba bwuruhande rwikibaho kirekire. Ihuriro rihuza ritunganijwe hejuru yikibaba cyuruhande rwibiti birebire kugirango wirinde hejuru yikibaba cyo hejuru cyikibaho kirekire kandi gifite impungenge nyinshi, bityo wirinde ikibazo cyo gutobora umwobo uterwa no guhangayikishwa cyane, no kuzamura umutekano wa imodoka
