Txheem
Ntawm cov hom kev siv lub tshuab kaw siv nyob rau hauv cov tsheb niaj hnub, muaj torsion bar, thiab tam sim no peb yuav sim los qhia koj rau nws ntau yam.
Dab tsi yog qhov torsion bar?
Cov lus piav qhia yooj yim uas peb muaj peev xwm muab tau yog tias nws yog kev ncua, nyob rau hauv uas lub torsion nqaj yog siv ua lub zog tiv uas tsuas yog ua haujlwm hauv ib qho kev coj ua nyob rau hauv torsion. Txhawm rau nce torsional elasticity, hlau yog siv rau kev tsim cov nqaj, uas tau ua ntau txoj hauv kev kho kom sov ntau yam.
Ib tug yam ntxwv feature ntawm lub torsion bar ncua kev kawm ntawv yog hais tias ib kawg ntawm lub torsion bar yog txuas rau lub log, thiab lwm yam kawg, nyob rau hauv tib txoj kev, rau lub tsheb lub cev. Ob qhov kawg ntawm torsion yog txav tau, uas yog ua tiav los ntawm kev siv cov bearings thiab cov pob qij txha los them rau cov kev hloov pauv los ntawm kev thauj khoom thaum lub sijhawm txav.
Yog li, lub axis ntawm kev sib hloov thiab lub axis ntawm torsion bar tseem nyob hauv kab, lossis ua lwm yam lus, thaum lub log tsoo lub tsoo, torsion bar khoov muab qhov txuas txuas ntawm qhov kev ncua thiab lub cev tsheb.
Txoj kev tshem tawm no tau muab ntsia tau ntev lossis hloov chaw. Longitudinal torsion bar ncua siv feem ntau hauv cov khoom hnyav uas qhov chassis tau raug lub nra hnyav. Lub tsheb sib xyaw torsion bar raug rho tawm feem ntau yog nruab rau cov tsheb thauj neeg.
Lub ntsiab tseem ceeb uas ua rau rub tawm lub torsion bar ncua yog:
- tsav ntug;
- qis qis thiab sab xub pwg;
- poob siab nqus;
- stabilizing bar;
- pem hauv ntej plawg;
- subframe.
