Roj hmab bushings ua hauj lwm los ntawm kev siv elastic deformation rau tsis, cais, thiab nqus lub zog cuam tshuam los ntawm txoj kev nto, thaum tso cai rau chassis Cheebtsam txav kuj nyob rau hauv ib tug tej yam ntau yam, yog li txhim kho lub tsheb kev nplij siab thiab tuav stability.
Thaum lub sijhawm ua haujlwm ntawm lub tsheb, txoj kev ua pob yog kis mus rau lub kaw lus ncua los ntawm cov log tsheb. Raws li "elastic joint" txuas chassis hlau Cheebtsam (xws li tswj caj npab, subframe, stabilizer tuav, thiab lwm yam), cov haujlwm tseem ceeb ntawm cov roj hmab bushings yog:
Buffering thiab Shock Absorption: Thaum lub tsheb taug kev hla txoj kev tsis sib xws, cov khoom siv roj hmab deforms, nqus lub zog thiab txo cov kev vibrations ncaj qha mus rau lub tsheb lub cev, ua rau lub caij smoother.
Kev rho tawm kev vibration thiab txo suab nrov: Roj hmab muaj cov khoom zoo damping, zoo sib cais siab - zaus vibrations thiab txo cov suab nrov "creaking" tshwm sim los ntawm nruj kev sib txuas ntawm cov hlau qhov chaw, txhim kho NVH (Noise, Vibration, thiab Harshness) kev ua tau zoo.
Kev Tswj Xyuas Qhov Tseeb: High- bushings zoo tuaj yeem ruaj ntseg kev sib txuas, tiv thaiv lub log sib dhos tsis zoo vim kev xoob, thiab zam cov teeb meem xws li lub log tsheb tsis sib xws thiab lub kauj tsheb tsis ruaj khov.
Kev cuam tshuam rau kev tuav teb: Bushing txhav cuam tshuam rau kev ncua ntawm K&C yam ntxwv (kinematics thiab elastokinesis). Mos bushings nyiam qhov tseem ceeb ntawm kev nplij siab, thaum lub bushings nyuaj txhim kho lub kauj precision thiab kev tswj tsheb.
Tsis tas li ntawd, ntau hom bushings optimizes kev ua tau zoo:
Hydraulic bushings muaj cov roj chamber. Thaum lub sij hawm deformation, cov ndlwg ntawm cov roj generates ntxiv damping, ua kom tiav ib tug dual nyhuv ntawm "mos nyob rau hauv thaum pib thiab txhawb thaum kawg," ho txhim kho tus nqi zoo.
Polyurethane bushings yog ib qho nyuaj thiab muaj qhov me me deformation, haum rau kev hloov kho kev ua haujlwm nrhiav txoj kev xav zoo tshaj plaws, tab sis ntawm kev siv qee qhov kev nplij siab.
