Indlela ukukhetha ibhayisikili ngoba ekwehleni

Ubuchwepheshe obunobuhlakani kancane kancane kuphenduke ephelele imoto ezokuthutha ezimbili ezinamasondo. Ukuqinisekiswa kufeza ibhayisikili ngoba ekwehleni. It ikuvumela ukuba ukugibela ngoba kumnandi futhi ngesikhathi esifanayo enze stunts ekhungathekisayo emithambekeni eziqongweni entabeni.

Ukuze uthole ukwaneliseka ezigcwele kusuka emidlalweni eyingozi, kudingeka uqonde ukuthi ukukhetha ibhayisikili ngoba ekwehleni. Ake sizame ukuqonda ngale ndaba.

Kafushane mayelana daunhille

Downhill - ngebhayisikili ezemidlalo isiyalo, ngokuyisisekelo eyinhloko okuyinto ilungiselelo lokunqoba izigaba ngesivinini sezwe esingaweleki sezintaba ezimangelengele. Elivame ezindaweni zakoryazhennymi eziminyene, oshelelayo, izingodo ehlakazekile aqukethe umyela ^ngu-45 °.

Ngokuba ukuthuthukiswa isiyalo ekuqaleni kwekhulu abakhiqizi elihle wasiphakamisa ukuthuthukiswa emabhayisikili ekhethekile, prototypes, okuyizinto kakhulu ekuphambukeni nge ngcono ikhono ukushaqeka-omnandi Ushintshe ukumiswa labaqaphi elingemuva.

Uhlaka

Vele kanjani ithembekile, ukhululekile futhi ephumelelayo kuyoba ibhayisikili ngoba ekwehleni ngesikhathi idrayivu, ke kuncike kakhulu ukukhiqizwa impahla uzimele. Cabanga izixazululo ezivamile.

1. Aluminium - ukwenziwa amabhayisikili kulesi sigaba zisebenzisa amaningi ingxubevange yezinto ezibonakalayo. Uchungechunge wesithupha ozimele adumile njengoba ingxenye eyengeziwe isetshenziswa magnesium, esiza ukwandisa amandla futhi ukunciphisa isisindo isakhiwo. I last kube yimanje - uchungechunge lwesikhombisa, zinc isetshenziswa, ngaleyo ndlela kuncishiswe izindleko ingqikithi ibhayisikili.
2. Steel - ukukhiqizwa kwe onobuhle samanje impahla cishe ungalokothi ukusetshenziswa ngoba, naphezu ohlangothini ukuphepha, elinesimo isisindo omkhulu. Kodwa uma ukhetha ngebhayisekili uhlelo ubudala ekwehleni, ozimele ezinjalo ingasatholakala.
3. Carbon - impahla ezibizayo. Nokho, ngokweqile kunalokho okunemibandela kusukela ikhambi elinjalo ikuvumela ukuba ungakhathazeki mayelana nokumelana ifremu umonakalo lokukhanda. Isisindo isakhiwo kungaba aphansi uma kuqhathaniswa ne-aluminiyamu efanayo.
4. Hromol - Umhlangano wokugcina Hamba Downhill senzeka ngokunembile ngesisekelo material esinjalo, Inzuzo enkulu esebenza akunamthelela yokukhathala e beya futhi eguqa. Ngamanye amazwi - ngisho ngesikhathi nesenzakalo ukuqhekeka at emalungeni izingxenye ngabanye kungenziwa kalula aqedwa Welding ngaphandle ngincipha ngamandla isakhiwo sokuqala.

ukumiswa

Uhamba ngebhayisikili Downhill - imoto, libhekene ukuthuthukiswa oda 60 km / ijubane h nasekubulaleni kuzuba akhuphuke imimmango. Hamba ukumelana nakakhulu leyo misebenzi, uhlelo ukumiswa ekhethekile ngokunqaba design.

Omunye ezivamile izenzo ezine-isixhumanisi ukumiswa, okuvumela amasondo ukuhambisa phezulu kuphela, hhayi ukuguquguquka ngase esihlalweni. Ngokuqondene ethandwa olulodwa-isigwedlo izinhlelo, lona wamuva ukunikeza ephelele pass nezimagqabhagqabha engalingani. Kulokhu umphumela kakhulu esincishisiwe unyakazisa ibhayisikili lapho ukushova.

ekuphambukeni

Eyesibili ingxenye esiyisibopho Uhlaka emva ekwehleni-ibhayisikili imele dvuhkoronnaya ukumiswa ekuphambukeni. izixazululo ezinjalo zisetshenziswa emhlanganweni izithuthuthu kanye ukuvumela ukwandisa rigidity torsional.

amasondo

Ngu Hamba Downhill akhethiwe okuqinile, amasondo onohlonze. Izinkomba yokumelana ukucindezeleka lapha incike isinqumo kahle spokes, kanye inhlangano efanele.

izincomo Specific kukhethwa amasondo kunzima. Okuningi kuxhomeke ogibele isitayela, isimo sezwe, lapho ukuhamba oyokwenziwa. Ezimweni eziningi kwanele makudle amasondo abakhiqizi elihle.

amabhuleki

Emabhayisikili kangcono ekwehleni aqukethe ezibizayo, eliphezulu ukubopha izinhlelo. Kubaluleke kakhulu ukuthi udale ukuzikhandla okukhulu. Ukukhetha ukuba lapha phakathi onobuhle amane nezimbili-piston. Oluthandwayo Kunconywa ukunikeza kangcono nokuthi athembeke samuntu kuqala.

derailleurs

Ngo zasemadolobheni kanye bike mountain amamodeli kabanzi njengendlela derailleur ezingemuva futhi front. Ngo ukuzithiba ekwehleni bathembele kakhulu kwi ezingemuva, ngoba Uzalo okusheshayo asikho isidingo ukushintsha amagugu in ezahlukene.

Phakathi izinhlelo iyatholakala babe nokwethenjelwa eliphezulu, kuyafaneleka ukushintsha Sram X7 futhi Sram X9. Ukukhethwa ongakhetha ezinjalo ngenxa operation esitebeleni futhi engambi eqolo.

Ekuphetheni

Ngaphambi kokuthenga ibhayisikili ngoba ekwehleni kufanele bacabangele imininingwane isiyalo esithile. Uma wayefisa, ukusetshenziswa kungaba isithuthuthu futhi ekuphileni kwansuku zonke. Nokho, akulula kanjalo, futhi kunzima nakakhulu. Ngakho, kufanele isinyathelo eside imile sokuthuthukiswa isivinini abaphendula ngokunengqondo. Uma udinga ukuba akwazi ukunqoba izingqinamba okhuphukela eyayizothatha isikhathi eside emaweni, ibhayisikili futhi zonke bayaphoqeleka ukuthi bahambe ngezinyawo. Ngakho-ke, uma wahlanganyela ogibele kakhulu sihlelelwe izikhathi eziningana ngenyanga, ukuthenga izimoto ezibizayo ubukeka engasimeme.
