Ngaba iidiskhi zebrake zangaphambili ziyafana neediski zebrake yangasemva?
I-disc ye-brake yangaphambili kunye ne-disc ye-brake yangasemva ayifani, i-disc ye-brake yangaphambili kunye ne-disc ye-brake yangasemva nganye idlala indima ebalulekileyo kwinkqubo yokunyathela isithuthi, kwaye kukho ukungafani okukhulu phakathi kwabo. Okokuqala, xa umqhubi ecinezela i-pedal pedal, ngenxa yendima ye-inertia, umphambili wesithuthi uya kucinezela, kwaye umva uya kuthambeka. Le nto ibangela ukuba itayara langaphambili libe noxinzelelo olukhulu ngexesha lokuqhobosha. Ngenxa yoko, iidiski ze-brake zangaphambili kufuneka zimelane nokunyanzeliswa kwe-braking ukuze kuqinisekiswe ukuba imoto inokumisa ngokukhawuleza kwaye ngokufanelekileyo. Oku kuthetha ukuba iidiski ze-brake zangaphambili kufuneka ziyilwe kwaye zenziwe ngamandla aphezulu kunye nokumelana nokunxiba.
Okwesibini, indima yediski yebrake yangasemva kwi-brake braking yongxamiseko yahlukile kuleyo ye-front brake disc. Ekubeni umphambili wemoto ucinezela phantsi emhlabeni ngexesha lokunyathela, amavili angasemva aphakamisa ngokufanelekileyo. Ngeli xesha, amandla oqhagamshelwano phakathi kwevili elingasemva kunye nomhlaba (oko kukuthi, ukubamba) kuncitshisiwe, ngoko akukho mfuneko yamandla amaninzi okuqhawula njengevili langaphambili. Nangona kunjalo, i-disc ye-brake yangasemva isafuna ukuba nesakhono esithile sokunyathela ukuqinisekisa ukuba isithuthi sinokumisa ngokukhuselekileyo kwiimeko ezahlukeneyo zendlela kunye neemeko zokuqhuba.
Ukongeza, i-disc ye-brake yangaphambili idla ngokuba nkulu kune-disc ye-brake yangasemva, kuba amavili angaphambili afuna amandla amaninzi okunyathela ukuqinisekisa ukuba isithuthi sinokumisa ngokukhawuleza nangokufanelekileyo. Kwi-braking engxamisekileyo, kuba indawo engaphambili yomzimba inyanzeliswa phantsi, ivili elingasemva liya kuphakamisa, emva koko amandla oqhagamshelwano phakathi kwevili elingasemva kunye nomhlaba (oko kukuthi, ukubamba) awukho mkhulu njenge ivili langaphambili, ngoko ke ayifuni mandla okuqhobosha kangaka.
Ngamafutshane, indima ye-disc ye-brake yangaphambili kunye ne-disc ye-brake yangasemva kwinkqubo yokuqhawula yahlukile, umahluko ophambili kukuba bamelana namandla okunyathela kunye neemfuno zokumelana nokunxiba. Olu yilo luqinisekisa ukunyanyiswa okusebenzayo kunye nokukhuselekileyo kuzo zonke iimeko zokuqhuba.
Ngaba iqhelekile ukuba idiski yebhuleki yangaphambili ibe shushu
I-disc ye-brake yangaphambili ishushu kumlinganiselo othile iyinto eqhelekileyo, kodwa ukuba iqondo lokushisa liphezulu kakhulu lingabonisa ingxaki.
Xa inkqubo ye-brake yesiqhelo isebenza, i-friction phakathi kwe-brake pad kunye ne-disc ye-brake iya kuvelisa ubushushu, ngoko kuyinto eqhelekileyo ukuba i-disc ye-brake ishushu. Ngokukodwa emva kokuqhawula rhoqo okanye ukunyathela ngokukhawuleza, ukufudumeza kwe-disc ye-brake kuya kubonakala ngakumbi. Nangona kunjalo, ukuba iqondo lokushisa le-disc ye-brake lidlula uluhlu oluqhelekileyo kwaye liba shushu okanye lishushu, lingabonisa ukuba kukho imeko engaqhelekanga. Ezi meko zingaqhelekanga zingabandakanya ukubuya kakubi kwempompo yokuqhawula, ukungaphumeleli kwamacandelo e-brake system, kunye ne-disc ye-brake kunye ne-brake pads azihlulwe ngokupheleleyo. Ezi ngxaki zingakhokelela ekufudumeni okugqithisileyo kwe-disc ye-brake, efuna ukulungiswa ngexesha elifanelekileyo ukuphepha iingozi zokhuseleko.
Ngoko ke, ukuba ufumanisa ukuba idiski ye-brake yangaphambili ishushu, ungayiqwalasela ixesha elithile. Ukuba amaqondo obushushu aqhubeleka ukuba phezulu kakhulu okanye kukho ezinye izinto ezingaqhelekanga (ezifana nokuqhobosheka okungaqhelekanga, ukwehla kwempembelelo yebrake, njl. njl.), kufuneka uqhagamshelane nabasebenzi bolondolozo kwangethuba ukuze uhlolwe kwaye ugcinwe.
Izizathu zokunxitywa okunzulu kwediski ye-brake yangaphambili xa kuthelekiswa nediski ye-brake yangasemva ikakhulu ibandakanya uyilo loyilo lwesithuthi, ukuhanjiswa kobunzima obungalinganiyo phakathi komphambili nasemva, kunye nokuhanjiswa kobunzima ngexesha lokuqhotsa.
Uyilo loyilo lwemoto: Uninzi lweemoto (kubandakanywa neeSUV zasezidolophini) zamkela uyilo olungaphambili-ngaphambili, apho injini, uthumelo, itransaxle kunye namanye amacandelo amakhulu kunye neChengdu iyonke ifakwe kwisiqingatha esingaphambili semoto. Olu lungiselelo lubangela ukusabalalisa ngobunzima obungalinganiyo ngaphambili nangasemva kwemoto, ngokuqhelekileyo ukufikelela kumlinganiselo we-55:45 okanye 60:40. Kuba amavili angaphambili anobunzima obuninzi, ngokwendalo athwala amandla angaphezulu okuqhobosha, nto leyo emisela ukuba inkqubo yokuqhoboshwa kwevili langaphambili lesithuthi kufuneka yomelele kunevili elingasemva.
Ukusasazwa kobuninzi obungalinganiyo ngaphambili nangasemva: Ngenxa yokungalingani kobuninzi besithuthi esingaphambili nangasemva, amavili angaphambili kufuneka athwale ngamandla okuqhobosha. Ukuze wenze ivili langaphambili libe namandla okuqhobosha, kuyimfuneko ukwenza iipakethi zokuqhobosha kunye neediski zokuqhobosha zevili langaphambili zibe nkulu. Olu yilo lwenza ukuba ubukhulu bediskhi yebhuleki yevili langaphambili buqhele ukuba yi-15 ~ 30mm enkulu kunesondo elingasemva, ukwenzela ukwandisa i-torque kunye nesiphumo sokuqhafaza.
Ukugqithiswa kweMisa ngexesha lokunyathela: xa imoto ibhobhoza, nangona ivili liye lacotha de liyeke, kuba umzimba kunye nesondo zixhunyiwe ngokuguquguqukayo, umzimba uqhubeka uqhubela phambili phantsi kwesenzo se-inertia, ukwenzela ukuba iziko lomxhuzulane. yemoto ikhutshelwe phambili. Le nto ibizwa ngokuba yi-brake mass transfer yesithuthi. Imoto iya kuba nenxalenye eyongezelelweyo yobunzima bongeziweyo kwivili langaphambili xa i-braking, kwaye ngokukhawuleza isantya, i-braking enobundlobongela, ukuhanjiswa okukhulu kobuninzi, umthwalo omkhulu kwivili langaphambili. Ngoko ke, ukwenzela ukulungelelanisa oku kunyuka komthwalo, ukunyanzeliswa kwe-braking of the front wheel kwandisa ngokufanelekileyo, ngoko ke kuyimfuneko ukusebenzisa ubungakanani obukhulu beepads kunye neediski zokuqhawula.
Isishwankathelo, ngenxa yoyilo loyilo lwesithuthi, ukusabalalisa kobunzima obungalinganiyo ngaphambili nangasemva kunye nokugqithiswa kobuninzi ngexesha lokuqhawula, i-disc ye-brake yangaphambili igugile kakhulu kune-disc ye-brake yangasemva. Olu luyilo kukuqinisekisa ukuba amavili angaphambili anokubonelela ngamandla okuqhobosha okwaneleyo ngexesha lokuqhobosha ukugcina uzinzo kunye nokhuseleko lwesithuthi.
