Kungani ngidinga iqhude ngebhayisekili?

Ngesikhathi abantu engaqaliwe ukusho lesi sici ibhayisikili kubangela uhleko kuphela. Nakuba, naphezu lingakanani enesizotha, ifeza indima ebaluleke kakhulu. Rooster ngesithuthuthu - kungcono ipuleti encane esikhiphekayo elikuvumela ukuba silungise yokuma derailleur labaqaphi elingemuva. Ingqikithi ubufakazi bokuba khona kwalesi umnikazi ukuthi kuvimbela umonakalo kungenzeka uzimele phezu umthelela. Ngempela, ngesikhathi wamabhayisikili ka derailleur yayo ezingemuva ngokuvamile ukunamathela ezihlabayo noma ezinye izimila. Lokhu ingozi ngeshwa futhi Kugqashuka into encane consumable, kuyilapho bonke kwezinye izingxenye aziphazamiseki.

Hindsight

Umlando ukuthuthukiswa, okuyinto waphoqeleka ukuba ibhekane iqhude ngebhayisikili, kuyathakazelisa kakhulu. Iqala kusukela ozimele yokuqala zazenziwe steel futhi babe nesisindo abalulekile. Ngalezo zinsuku, derailleur isananyathiselwe ngqo, ngoba ingxubevange zensimbi, okuvela kulo Uhlaka nezimo futhi wakhuthazelela umonakalo lokukhanda. Kusukela ngaleso sikhathi, kwathatha isikhathi esiningi, futhi mores zishintshile. Uhlaka Modern eyenziwe carbon fibre noma se-aluminium, okuyizinto engasindi, kodwa kakhulu rigidity ntathu. Nokho, lezi zinto kufanele ukhokhele izinzuzo zabo fragility - uma kwenzeka i iphuzu isicelo ka okudlulisela umqondo wokuzikhandla, balahlekelwa ubuqotho babo nokufakazela iba yingxenye yomhlabathi. Kuyinto ukuze ugweme imiphumela enjalo ngeshwa, futhi waqala ukwenza ibhayisikili iqhude kokuba amandla esingaphansi isakhiwo elisemqoka elifanelana nalo unamathele, - uzimele. Kwezinye izimo, lokhu kuyangisiza ekugcineni izingxenye consumable langemuva umsebenzi derailleur - emva ukushaya Ilokhi sinqamukile, futhi izingxenye abayi lilimele. Lokhu kunciphisa hhayi kuphela izindleko zezimali umgibeli, kodwa futhi kwenza kube isevisi imoto ngaphezulu yempucuko futhi izinga.

isicelo

Ngenxa yalokho, uma likhala ixhunywe ku luhlaka ibhayisikili wasethula ukwakhiwa wakhe ucezu, bekuyoba nakanjani kuholela ekutheni iloli njalo. Ngokungafani steel, i-aluminiyamu noma i-carbon fiber akuyona amenable ukuba imisebenzi Welding endaweni umoya zidinga amasu ezikhethekile ukubuyisela. Ngisho nangemva kokuba umsebenzi wokulungisa lezi zinto yilezi attenuation sasendaweni ngokuhlanganyela, ngakho ukusebenza kwabo ngemva umonakalo sincane kakhulu. Kulezi zimo, umbuzo maintainability kudingeke sicabangele ngokuya nenzuzo kanye nokufaneleka, kusukela izindleko yokutakula Uhlaka kungaba idlule intengo isampula esifanayo, muva nje ushiye endaweni yokukhanda. Ngakho-ke, ngemva Uhlaka umonakalo lapho igibele ibhayisekili yonke imishini, ilahlwe. Kutholwa kuphela amafulemu eyigugu ngaphezu kwazo zonke kukhona okukhethekile, noma une-value zomlando elingenakuphikwa. Ngakho-ke, ezikhathini eziningi lula kakhulu ukuba esikhundleni Iqhude ngebhayisekili ungayembethe amandla elikhulu, elingase ngemva kokuthola le ukusonteka kuyoba ngonembeza omuhle balahlwe. A Uhlaka ihleli kahle.

umehluko

Phakathi ngendlela, ngamunye abakhiqizi wazama ukwethula into entsha ku-klamo ibhayisikili. Izinguquko Ezenzeka engavikelekile kanye iqhude ngebhayisekili kusuka izingxenye liyabonakala futhi elula ibe umkhiqizo original kakhulu. Ziyashiyana design, isibalo izimbobo, indaba (aluminium, carbon fibre noma polymer Ukwakheka) futhi, yebo, interchangeability. Manje, ezingemuva derailleur ngocingo uhlukile ngemodeli ngayinye ibhayisikili, ngakho kwaso indawo kungaba nzima. ububanzi Esanele akuyona njalo ngisho kusuka wabenza ezisemthethweni abenza ukuqaliswa brand lesitsite e injongo yaso. Ngakho ngokuvamile kufanele iphendukele ngosizo lochwepheshe, nokuwakhiqiza ngokufunwa, noma ukukwenza yena. Phela umsebenzi okumele wenziwe, hhayi indawo ebanzi kakhulu - kubalulekile bayamba izimbobo ezindaweni ezifanele, bese usika uhlaka, elihambisana izihlalo imininingwane. Uma ekuqaleni ungenalo aphumelele ukugcwalisa ke ungalilahli ithemba, kwanele ukusingatha Ilokhi ifayela - futhi kuzothatha isikhundla salo esabiwe.

Imiphumela

Sethemba, manje ukuthi Wabasaqalayo kungaba kungabaza ngokuthi iqhude enjalo ngesithuthuthu futhi iyini injongo yaso. Ngenhlanhla, izikhathi lapho lezi zinto Abantu ababengewona ama-esikhiphekayo, sekuyisikhathi eside ashona la mavangeli. Eqinisweni, bambalwa abanikazi emabhayisikili ubudala kusadingeka ukushisela iqhude ngemva zokugwema ukuphuka ngamunye.
