Ntau hom tsheb siv ntau hom kev sib txawv. Piv txwv li, lub tsheb tsav tsheb yuav muaj "plaub-txuas" crossmember uas txuas lub qag nram qab mus rau lub chassis. Lub tsheb pem hauv ntej-log tsav yuav muaj "subframe" crossmember uas txhawb nqa lub cav thiab kev sib kis.
Vim li cas tus Crossmember tseem ceeb?
Ib tug neeg hla kev ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb thiab tuav lub tsheb. Yog tias tsis muaj cov neeg sib tw uas muaj zog thiab ua tau zoo, lub tsheb lub thav duab tuaj yeem ua rau flexing thiab twisting thaum lub sij hawm acceleration, braking, thiab cornering. Qhov no tuaj yeem ua rau muaj ntau yam teeb meem, xws li lub log tsheb tsis sib xws, kev tuav tsis zoo, thiab kev puas tsuaj ntawm cov qauv.
Ib qho ntawm cov haujlwm tseem ceeb tshaj plaws ntawm tus neeg sib tw yog nqus thiab faib lub zog thaum muaj kev sib tsoo. Thaum muaj kev sib tsoo, tus crossmember pab kom dissipate lub zog ntawm kev cuam tshuam thiab tiv thaiv kev puas tsuaj rau cov neeg caij tsheb. Qhov no tuaj yeem ua rau kom muaj kev nyab xeeb ntawm lub tsheb cov neeg nyob.
Tsis tas li ntawd, tus tsim qauv tsim thiab ntsia tau zoo tuaj yeem txhim kho lub tsheb ua haujlwm thiab tuav. Los ntawm kev muab kev nruj ntxiv rau lub chassis, tus ntoo khaub lig tuaj yeem pab txo qis thiab torsion, ua rau muaj kev tuav ntau dua thiab kev caij tsheb zoo dua.
Kev xav zaum kawg
Nyob rau hauv cov ntsiab lus, ib tug crossmember yog ib qho tseem ceeb ntawm lub tsheb kev nyab xeeb, tuav, thiab kev ua tau zoo.
