Crossmember inonziwo sub-frame, iyo inoreva tsigiro inotsigira kumberi uye kumashure maekisi uye kuturika kuitira kuti zambuko uye kuturika kwakabatana ne "mainframe" kuburikidza nayo. Mushure mekuiswa, inogona kuvharira vibration uye ruzha uye kuderedza yakananga kupinda kwayo mungoro. inzwi re.

Kazhinji, iyo crossmember inoda kuomarara kwakanyanya maererano nechimiro. Pedhi yerabha inogona kuwedzerwa pakati peiyo mainframe uye crossmember. Kana iyo mainframe yakaremara, iyo elastic rabha inokanganiswa kuti iite zinyekenyeke kuzvidzora kweiyo crossmember pane mainframe. Teerera kune crossmember. Kana iyo crossmember yakarongedzwa pane chassis yemotokari, magumo ayo epamberi anofanira kunge ari padyo sezvinobvira kumadziro ekumashure ekombi.

A-frame crossmember assembly inosanganisira crossmember uye bracket yekubatanidza. Chikwata chekubatanidza chine pamusoro pepamusoro uye nechepamusoro. Iyo yepamusoro peiyo yekubatanidza bracket yakabatana pazasi peinotsigira poindi yecrossmember, uye padivi pechiso chekubatanidza bracket yakabatana nedivi rebapiro pamusoro peiyo furemu longitudinal danda Mukati. Iyo yekubatanidza bracket yakarongedzwa padivi rebapiro pamusoro peiyo furemu longitudinal danda kudzivirira iyo yepamusoro bapiro pamusoro peiyo furemu longitudinal danda nekunyanya kushushikana, nekudaro kudzivirira dambudziko reriveting gomba kupaza kunokonzerwa nekushushikana kwekushushikana, uye nekuvandudza zvakanyanya kuchengetedzwa kwe. motokari
