Kana iyo nzira mbiri yekunyorovesa pulley yakapihwa nerimwe bato isina clutch inodarika, inogona kunyanya kugadzirwa nerabha yakasungwa nekunze rin'i yesimbi, uye mhete dzemukati nekunze dzinozadzwa nerabha yakakosha.Iyo yekunyorovesa nzira yerabha yakafanana neyekunyorovesa chitubu, iyo inogona kuderedza resonance amplitude panguva yekushanda kwepulley uye inonoke kumhanyisa panguva yekuchinja nekukurumidza.Edza kuwana shock absorption.Sezvatinoziva, iyo chaiyo yekunyorovesa mhedzisiro yeiyi bhandi pulley haisi pachena, nekuti haina basa rekupfuura clutch, kukanganisa kwekudzikisa kukurumidza kuchinja kunogumira, uye kune jenareta ine nguva yakakwira inertia. , haigoni kuramba ichitenderera inertia uye kumira zvishoma nezvishoma, uye haigoni kunyatso uye kudzivirira jenereta.
