Rudzi urwu rwemasiraidhi njanji yakavanza masiraidhi njanji, bhiza-inotsvedza njanji uye mamwe masiraidhi njanji. Iyo ndeyepakati uye yepamusoro-yekupedzisira masiraidhi. Chimiro chegiya chinoshandiswa kugadzira masiraidhi njanji yakatsetseka uye yakawiriraniswa. Iyi mhando yemasiraidhi njanji zvakare ine buffer yekuvhara kana kudzvanya rebound. Basa rekuvhura rinonyanya kushandiswa pakati nepamusoro-soro fenicha. Nemhaka yokuti mutengo wacho unodhura zvikuru, hauwanzowanikwi mufenicha yemazuva ano, saka haina kufarirwa sesimbi bhora masiraidhi. Rudzi urwu rwemasiraidhi ndiyo mafambiro emangwana.

Iyo inonyorovesa inotsvedza njanji imhando yenjanji inotsvedza, inova imhando yeinzwi-inokweva uye bhafa mhedzisiro inopa kuita kwebuffering uchishandisa mvura uye yakanaka buffering maitiro. Iyo otomatiki sarudzo yemasiraidhi njanji inosanganisirwa. Inotsamira pane tekinoroji nyowani kuti ienderane nekumhanya kwekuvhara kwedhirowa. Kana dhirowa yakavharwa kusvika kune yekupedzisira chinhambwe, inoshandisa hydraulic pressure kuti inonoke kukurumidza, kuderedza simba rekuita, uye kuumba mhepo yakagadzikana pakuvhara. Kunyangwe iwe ukashandisa simba kusundira dhirowa, rinovhara zvinyoro nyoro, kuve nechokwadi chekufamba kwakanaka uye kwakanyarara. Kusanganisira njanji yakagadziriswa, njanji yepakati, njanji inofambiswa, bhora, clutch uye buffer, iyo buffer inoiswa mune yakatarwa njanji; iyo buffer inosanganisira piston tsvimbo, shell, uye piston. Iyo piston inopihwa neburi negomba, uye piston tsvimbo inotyaira Kana piston ichifamba, mvura inogona kuyerera ichibva kune rumwe rutivi ichienda kune imwe kuburikidza neburi, nekudaro ichiridza buffering uye damping effect. Inowanzoshandiswa kusunda uye kudhonza madhirowa.
