Ukukhetha Ijiyomethri Elungile Yohlaka lwe-MTB

Kulesi sihloko sobuchwepheshe sejiyomethri yebhayisikili lezintaba, sihlanganise zonke iziqephu ze-C'est pas socier ukuze zicace futhi zifundise njengo-Jamie. Ungasazisa emazwaneni ekupheleni kwesihloko uma sesiwuqedile umsebenzi wethu!

Ufuna i-ATV entsha?

Yiya esitolo sakho osithandayo ukuze uzame.

Yebo, siyakukhuthaza ukuthi uzame amabhrendi ambalwa uze uthole eyakho - okwamanje, ngoba okuthandayo, ukwenza kwakho, kanye nokumila kwakho kuyashintsha ngokuhamba kweminyaka.

Ngakho sithe, uzama amabhayisikili asezintabeni. Usayizi ofanayo, uhlobo olufanayo lwebhayisikili lezintaba, kodwa awuzizwa ufana, awuzizwa ukhululekile kuwo wonke.

Isizathu? Ijiyomethri yebhayisikili.

Yenzelweni iMountain Bike Geometry?

I-ATV iqukethe izingxenye ezintathu eziyinhloko:

• ifreyimu;
• imfoloko
• amasondo.

(Ngemva kokwengeza isihlalo, izibambo, amaphedali, kuyindaba yokunethezeka nokusebenza.)

Okwamanje, wonke umuntu ubukele? Kulungile, asiqhubeke.

Nokho, i-geometry ye-quad yakho iyinhlanganisela yalezi zici ezintathu nayo yonke into eza nazo (ubude beshubhu, ama-engeli, njll.).

Isakhiwo sonke sebhayisikili lakho (yingakho ijometri yalo) ithonya amapharamitha amaningi, ikakhulukazi, isitayela sakho sokugibela.

Nakuba ingeyona impendulo kuzo zonke izifo zakho, i-geometry engavumelani ne-morphology yakho ingase futhi ibangele ukungakhululeki okuncane, okuye kube okucasulayo nakakhulu phakathi nokuhamba okude. Kungenzeka ukuthi uhlangabezane ne-geometry engalungiswanga kahle (isixhumanisi esithi Ungakhetha Kanjani Usayizi We-MTB Olungile futhi Ulungise i-MTB Ukuze Ugweme Ubuhlungu Bedolo), kodwa lezi zilungiselelo azisoze zathatha indawo ye-MTB elungele uhlobo lomzimba wakho nohambo lwakho. isitayela.

Ukuqonda i-Mountain Bike Geometry

Uhlaka lwebhayisikili yasezintabeni

Silwela ukunciphisa usayizi wefreyimu ubude beshubhu yayo ephezulu. Eqinisweni, i-engeli yeshubhu yokuhlala enquma ubukhulu bohlaka.

Naka izinto ezintathu:

• ibanga elivundlile phakathi kwe-crank axis kanye ne-fork axis (finyelela);
• ibanga eliqondile phakathi kwe-axis ye-crank kanye ne-axis yemfoloko (isitaki);
• ibanga elivundlile phakathi kwe-axis ye-crank kanye ne-axle yesondo yangemuva (i-chain stays).

Kungenxa yale datha ukuthi uzolungisa isiqu futhi, ngakho-ke, unqume isikhundla sakho ngebhayisikili.

Uhlaka lwebhayisikili yasezintabeni nemfoloko

Manje ake sibheke ohlangothini lwemfoloko nokuthi ixhuma kanjani kuhlaka. Ngoba, njenganoma iyiphi iresiphi, akuyona nje ikhwalithi yezithako ezibalulekile, kodwa futhi nendlela ezikhishwa ngayo futhi zixutshwe.

Ukuze siqonde ukuziphatha kwebhayisikili lezintaba, sizophinde sibheke idatha emithathu:

• ibanga phakathi kwe-axis ye-crank kanye ne-axis yesondo langaphambili;
• ibanga phakathi kwe-ekseli yesondo langaphambili kanye ne-asi yesondo elingemuva (i-wheelbase);
• i-angle yemfoloko kanye ne-offset yemfoloko (i-roller angle).

I-roller angle yokuzinza kwebhayisikili lezintaba

Le ndaba yokuzingela amalahle kancane sizoyicacisa.

Eqinisweni, lokhu kuzokunikeza umbono wokumelana kwe-ATV nokuguqula isiqondiso ngakho-ke amandla okuzodingeka uwafake ukwenza lokho.

I-angle yokuqondisa kanye ne-caster encane, i-ATV izinzile, kodwa kuba nzima nakakhulu ukushintsha indlela. Ngakho-ke, i-cockpit kumele iphendule futhi ibe namandla: khona-ke sizofaka isiqu esifushane kanye nesibambo esibanzi.

Umthelela wejiyomethri yebhayisikili lezintaba ekuphatheni

Silapha, futhi uzoqonda ukuthi kungani bekumele senze lethiyori encane enqamulayo.

Ufunani ukuze ulawule kalula i-ATV? Ukuzinza nokuhleleka kuyizici ezimbili, empeleni, eziphambene. Kunzima ukuba ne-ATV kokubili ezinzile futhi eshesha kakhulu. Lokhu akunakwenzeka ngokomzimba, futhi i-geometry ichaza lokhu.

Uma ukhulisa amabanga abonakalayo ngenhla, kulapho ukhulisa khona ukuzinza kwe-ATV. Uma ufuna ibhayisikili elikwazi ukulawuleka ngaphezu kwakho konke okunye, uzowafinyeza lawo mabanga.

Icace kakhudlwana, akunjalo?

Kodwa empeleni kuba nzima nakakhulu, ngoba kumabhrendi ahlukene, ukufinyelela, isitaki, i-wheelbase, i-engeli enyakazayo, njll. kungahluka kakhulu ngosayizi wohlaka olinganayo (njengo-M noma L). Ngakho-ke, kuyadingeka ukuba uqaphele ngokukhetha usayizi futhi unake i-geometry oyifunayo. Kuma-geometry acishe alingane, kwamanye amabanga kuzoba uhlamvu M, kanti kwamanye kuzoba ngu-L.

Wazi kanjani uma udinga ukuzinza okwengeziwe noma ukushesha?

Kuya ngesivinini sakho kanye nohlobo lwezifundo ozilandelayo.

Uma ufuna ukushayela amakhilomitha ngeketango futhi ushayele ngesivinini sombani, okokuqala uzolwela ukuzinza. Ngakolunye uhlangothi, ngesivinini esiphansi, sidinga ibhayisikili lezintaba elisheshayo.

Ingabe umusha ezifundweni zobuchwepheshe? Khetha i-ATV ene-wheelbase enkulu kanye ne-engeli enkulu yokuqondisa. Izozinza ngesivinini esisheshayo futhi ikwazi ukulawuleka emagqumeni noma emathafeni.

Ngokuphambene, uyathanda izifundo zobuchwepheshe? I-engeli yerola kufanele ibe nkulu ukuze udale ukumelana lapho ushintsha isiqondiso. Kuzwakala kuphikisana, kodwa akunjalo. Lapho ezingela kanzima, umshayeli wendiza uzosebenza endaweni yakhe hhayi kukhiye wokuqondisa. I-wheelbase ye-ATV yakho kufanele ibe mfushane ukuze ijike ngokushesha futhi ibe lula.

Kukulesi sigaba sokugcina lapho sizothola khona amabhayisikili asezintabeni abadlali. Lawa amabhayisikili amadala adinga izinga elihle lobuchwepheshe lokushayela ngoba umgibeli kufanele asebenze kanzima ukuze abeke indawo yawo ye-gravity futhi akhiye isiteringi.

Abakhiqizi namuhla bafuna ukulinganisa i-geometry ukuze banikeze amabhayisikili asezintabeni ahlukahlukene. I-wheelbase yinde ngokwanele futhi ukujahwa kuphezulu kumabhayisikili asebenza kahle anesivinini esisheshayo. Indawo yomshayeli egxilile ivumela ukushayela okune-acrobatic okuncane, kodwa kudinga ukufundwa okuhle phansi, ukulindela okuhle, nokuhlola okunenjongo.
