Drum brakes - iyo inonzi " brake system", iyo inosanganisira tambo inotenderera. Mariri, kubhururuka kunogadziriswa kuburikidza nekusimudza pads pads kurwisa doro.
Sezvakangoita, pads muitiro yakadaro sedhiramu mabheki ari mukati mehurukuro pachayo. Kana iyo iripo kunze kweiyo yakagadzirwa-dhoni flat disk, zvino iyo nzira inonzi disk. Drum mabheki achiri achiri rudzi rumwe-tape. Mukugadzirwa kwakadaro, kubhururuka kunoitwa "nokufukidzira" doro ine bhanhire resimbi rakashandura bhenji.
Muchigadzirwa chakadaro, icho chine magirairi maviri ekushanda, kushanda kwebasa kunowedzerwa nekufambisa doro apo motokari iri kufamba. Munguva yebhanja, inomanikidza pads zvakanyanya. Hakuchina simba rakadaro pamaitiro e disk, sezvo disk inotenderera kune iyo inofanirwa kuenderera mberi kune kutungamirirwa kwesimba rinopisa. Apo mhepo inofamba mberi, shangu yepamberi inotanga kuita. Inotumidzwawo sechipiri cheshuhwe cheshe (kana zvisingaiti inonzi sehwe rekacheka rembambo).
Zvakakodzera kutaurira, chii chakakosha chemuganda wakabhururuka. Aya ndiwo mapadhi akaparara. Kuti vaite izvi, vane mbatya dzakagadzirwa nekukanganiswa. Uyewo mumagariro ayo akazara kune doro rakabhururuka, mabheki uye mabhirikoro. Yokutanga yemvura yakasanangurwa yakanyorwa pasi pekumanikidzwa, iyo iri mu hydraulic system, inowanikwa kubva pakutsvaira kwechigamba. Zvose zvinongororwa zvikamu zvakasungirirwa pahwendefa yezvokucheka (zvigadziriswa pasi).
Mukuwedzera, iyo doro mabheki ane pini (axles) yemabhedha akavhara, nzira dzinodzora kusununguka pakati pemudha uye pads, zvitubu zvinobata pidhi munzvimbo uye zvichidzidzisa mushure mekunge mutyairi achibudisa ibheji.
Uye, zvechokwadi, hazvibviri kuisa ruzivo rwezvinobatsira zveizvi. Inoshandiswa pamarori (kazhinji kazhinji) uye motokari. Kunyange zvakadaro inogona kushandiswa pamakumbo. Kubatsira kukuru kweiyo nzira ndiyo simba rayo. Kana kuti, ichocho chiri nyore kuti zvakanyanya kuwedzera kuburikidza nekuwedzera dhambwe yakakura nekufara. Nyaya iyi, zvinokwanisika kuti zvizadzise hutsika hwakakwana hwebhenji simba, iyo inofanirwa kumira uye kuderedza kutakura kunotakura (mabhazi, makoriki). Drum mabheki anodzivirirwa zvakakwana pamvura uye guruva, kana zvakanyanya - kubva pane zvavanoita. Pads panzira isina tsvina kana kuti isina tsvina haigoni kupera - iyi inhu hwakanaka kwazvo, iyo inoita kuti mhando igare yakasimba. Kana ukashandisa, iwe unogona kuita nyore nyore iyo midziyo yemotokari yekupaka mabheji. Mukuwedzera, nzira dzakadaro hadziiti kupisa kukuru, uye nekuda kweizvi, mvura isingasviki inoshandiswa inoshandiswa kushandisa doro rewaini-inogona kushandiswa. Kubatsira kwakadai uye kuva nechemberi mabheki. Zvakakodzera kucherechedza chirevo chimwe chete - maitiro avo ane zvishoma zvishoma, zvichienzaniswa ne diski.
