Ukushintshwa kwebhayisikili yebhayisikili ene-disc brakes. Yikuphi ama-brakes okungcono - i-disc noma isigubhu?

Izimoto eziningi zanamuhla zinamabhuleki e-disc ngaphambili nangemuva. Ezimodini zebhajethi, ukuxhuma kwangemuva kusekhona isigubhu. Lezi zindlela zibhekwa zingasebenzi isikhathi eside. Kodwa kungani abakhiqizi behlomisa izimoto ngamabhuleki anjalo? Cishe, kuyindaba yesifiso esifanayo sokugcina imali ekukhiqizeni. I-drum ibhethri isebenza, kodwa ukusebenza kwayo akukona kakhulu. Ukuguqula i-drum brakes ku-disc kufanele kuthuthukise umphumela. Ake sibone ukuthi lokhu kunjalo, nokuthi ngabe kuzothatha indawo yale ndawo.

I-Drum Brake Unit

Cabangela ukwakhiwa ngokujwayelekile. Kulesi simiso, kusetshenziselwa ama-pads amabili okugaya ama-semicircular shape.

Zifakwe ngaphakathi kwidramu yokuwasha. Olunye uhlangothi lwamapayipi alungiswa kahle, futhi ngakolunye uhlangothi bahlakulela nge-piston. Lokhu kusebenza lapho umshayeli ecindezela ukuhamba. Futhi ngaphezulu kwamandla, amandla e-piston azoqina.

Phakathi kwama-pads amabili yimithombo. Lapho umshayeli ekhishwayo, lezi ziphethu zibuyisela amaphakethe esikhundleni sazo eziyisisekelo. Zisetshenziswa ukuze isigubhu singadli.

Ngokusobala, umshini wokubhukuda wodubhu uhlukaniswe ngempela ngobuciko bomklamo. Kodwa intuthuko nokuthuthukiswa kobuchwepheshe bwanamuhla buqhubeka phambili, izinjini ziyaqhubeka. Lokho okusheshayo embonini yemoto kwakubonakala kungento engokoqobo, namuhla kuye kwabonakala kungabonakali. Ngokuvamile emgwaqeni, izimoto zihamba ngesivinini kuya ku-200 km / h. Lesi sejubane ngisho namabutho we-motorsport eminyakeni engama-40 eyedlule ibonakala sengathi iyamangalisa.

Kulezi zivinini, i-drum brake ayisakwazi ukubhekana nomsebenzi wayo oyinhloko. Ukusebenza kahle kulahlekile. Okokuqala, kanye nenkinga ye-brake kuphela yalesi siklamo, ishisa kakhulu amaphuzu. Ngakho ukuwohloka komsebenzi kahle.

Njengoba ukukhula okusheshayo namandla, onjiniyela nabaqambi babhekana nomsebenzi onzima wokuthuthukisa uhlelo lwe-braking. Futhi kwakungekho okunye okumele kwenziwe ngaphandle kokubuyela embonini yezindiza ukuze uthole usizo. Kulungile, ngoba ama-discs wokuqala ayifakwe endizeni. Khona-ke uhlelo ludluliswe ngempumelelo ezimotweni.

Idivayisi yamadivaysi disk

I-disk element ibhekwa njengenguquko entsha ekuthuthukiseni izinhlelo ze-brake. Ngaphambilini, ifakwe kuphela izindiza, kanye namaloli amakhulu. Lapha ijubane liphakeme futhi ubukhulu bukhulu. Ake sibone ukuthi lolu hlelo luhlelwe kanjani nokuthi ngabe i-drum bhisikizi ingashintshwa ibe yidiski.

Ngakho-ke, i-disk encane iyiswe kwi-axis yemoto. Kungaba kokubili ukuxhuma kwangaphambili nangemuva. Okubizwa okuthiwa i-caliper ihlelwe engxenyeni engenhla noma eceleni kwediski. Izindlela zalo zihlanganisa amapistoni futhi aphule amapayipi. Lapho umshayeli ecindezela ukugwedla, ama-pads agxiliwe ngaphansi kwesenzo se-piston. Kukhona i-disk phakathi kwalezi zinto. Ngakho kune-braking.

Izici ze-disc amabhuleki

I-Disk mechanism ikhiqiza kakhulu. Iphuzu liwukuthi i-patch yokuxhumana ayiyona imizimba ye-semicircular, njengokwesistimu yegubhu, kodwa ihambisana. Ngenxa yalokhu, ama-pads acindezelwe ngokumelene ne-disc ngokuqinile. Lokhu kwenza kube lula ukuphuza kakhulu ngokwengeziwe ngokusheshisa okuphezulu. Ukuguqula i-drum brakes ku-disk kuvumela izikhathi eziningi ukukhulisa ukusebenza kahle kwesistimu.

I-drum brakes iyashiswa, kodwa ama-brake e-disk nawo ayathwala imithwalo. Noma kunjalo, i-disc ihlile kangcono uma ushayela. Futhi emakethe ungathola izakhi eziphefumulayo nezakhiwe. Ukucabanga okuhlukile kunganciphisa ibanga lokuyeka ngezikhathi ezithile.

Ngabo bonke ama-pluses, kukhona nohlangothi olubi. Njengoba i-disc yokuxhumana ye-disc ne-shoe iphakeme, khona-ke bayaphuma ngokushesha kakhulu. Ngaphezu kwalokho, i-disc isusiwe ngokushesha. It is sewn by pads. Imithombo ye-last for the break disc is okungenani kathathu ngokulingana nokuphila kwedrub. Kuze kube yilapho kukhona ama-pads, kunzima ukusho. Izinga lokugqoka lixhomeke endleleni yokushayela. Ngokwesilinganiso, ama-disc amaphuzu ngesitayela sokuthutha esithule anele ama-25-30,000 km.

Izinzuzo kanye nokungalungile kwamabhuleki emigubhu

Kufanelekile ukuqala ngamasu okugubha. Zinenzuzo ethile. Amathrekhi ashibhile ekukhiqizeni. Ama-automakers amaningi ngoncedo lwabo alondoloze kumamodeli webhajethi. I-drum brake inomthombo obalulekile. Amapayipi ashintsha ngezikhathi ezinkulu (ezingaphezu kwezingkulungwane eziyikhulu), okusho ukuthi umnikazi uzochitha imali encane yokugcinwa.

Amaminithi afaka isikhala sokuxhumana esincane, ukusebenza kahle kwe-braking. Futhi, amasistimu amadrama ashisa ngaphezulu. Futhi njengoba idivayisi ivaliwe, umphumela wokuvimbela uyancipha. Okokugcina, isici segubhu kunzima kakhulu ukulondoloza.

Izinzuzo nokuqeda kwediski

Phakathi kwezinzuzo kukhona ukusebenza kahle kwenqubo ye-braking. Futhi, le nqubo ayifuni ukushisa kumazinga okushisa afana namadrama abo. I-disc brake ingcono ukuhlanza. Isici singashintshwa kalula uma kunesidingo. Bashintshe uma i-dis isincane kune-parameter ethile. Ubukhulu obuncane be-disc ye-brake yi-20 millimeters.

Ukulimala kufaka hlangana amaphuthi wokugqoka okusheshayo. Ngisho nokudla okubizayo kunomthombo omncane - kuphela ngamakhilomitha angu-30-40 000 kuphela. Futhi gqoka kanye nama-disks. Zanele ngokwezigaba eziyizinkulungwane eziyikhulu zamakhilomitha. Khonza la mabhuleki ngaphezu kwesigubhu. Ehlobo, ama-creaks angenzeka ngenxa yezingxenye zokugcina ezingalungile. Kubalulekile futhi ukuba uqaphele njalo izinga lokugqoka i-disc. Akufanele kube mncane kuno-20 mm.

Yilobu buncane obuncane be-brake disc elawulwa ngabakhiqizi abaningi. Kuboniswa ekupheleni kwengxenye yomkhiqizo futhi umkhiqizi ngamunye uhlukile.

Indlela yokubuyisela i-drum brakes nge-disc brakes

Yikuphi ama-brakes okungcono - i-disc noma isigubhu? Ngezimo zanamuhla, uhlobo lokuqala lwezinhlelo lungcono. Ukusheshisa ngisho nasemadolobheni amancane anabantu abengeziwe. Amandla enjini akhule, futhi usuku ngalunye oludlula izimoto zikhula. Ukuze uthole indawo, kufanele uthenge ama-bhisikidi amabili. Ukulondoloza nokuthenga izesekeli ezishibhile akufanelekile - nge-brakes amahlaya awonakele.

Ukudumala nokufakwa kwezakhi ezintsha

Ukushintshwa kwamabhuleki e-drum nama-disc bhisikidi kufanele kwenziwe egalaji ngomgodi, ku-flyover noma ekuphakameni. Ungasebenzisa i-jack evamile. Okokuqala, phakamisa imoto bese uyilungisa. Bese ususe isondo. Ngaphezu kwalokho, susa izikhonkwane ezibambe isigubhu. Lokhu akunakwenzeka ngaso sonke isikhathi, njengoba izinwele zezinwele zivame ukunamathela. Bese ususe idramu. Kuyinto elula kakhulu ukwenza lokhu ngokuthepha nge-mallet yenjoloba. Okulandelayo, susa i-cable yokupaka ikhebula, uphumule isilinda esibuhlungu. Thola amaphuthi nezinye izingxenye kusuka kubhubhu.

Beka ukufakwa kwezingxenye ezintsha kuhlanzwa ngokucophelela. Ebusweni, akufanele kube khona ukuphazamiseka noma ukungahleleki. Uma konke kuhambisane, ungaqhubeka usebenza.

Faka ihabhu, uyicindezele ngokuqinile ku-faceplate. Khona-ke amaphuzu amayunithi ohlangothini. Kulungile, bese kuthi konke kulula kakhulu - ku-faceplate ukufaka amabakaki, naku-hub - i-disc. Hlala ubeka isikhala. Khona-ke amalunga wabakaki aqinisiwe. I-hose ixhunywe ku-caliper, ama-pads afakiwe. Hlola ubuqotho bomugqa wokuwasha.

Kulokhu, ukuguqulwa kwamadraki ama-discs sekuphelile. Ungakwazi ukujabulela ukusebenza kahle kwe-braking system.

Isiphetho

Izimoto zebhajethi zinezigubhu. Kodwa zingashintshwa njalo ngama-disk analogs. Lokhu kuzothuthukisa ukusebenza kahle kwe-braking.
