ibhayisikili
* Uhlaka
Ukuthi ibhayisekili elisentabeni likhululekile ukuhamba ngalo, noma lilula futhi kulula ukulilawula, ukuphakama kwalo kungamelana kangakanani, lingasebenza isikhathi esingakanani, noma lingathuthukiswa, njll. Isihluthulelo ukubona uhlaka.
Kunezinhlobo ezimbili zozimele: ifreyimu engapheli, uhlaka lokumiswa okugcwele (ifreyimu yokuphela ethambile)
Yisho ukukhethwa kosayizi befreyimu elandelayo ngokulula: khetha ifremu ngokuya ngobude obujwayelekile, kufanele ukhethe ifreyimu evumelana nayo, lokhu kubaluleke kakhulu!
Idatha yesitayela neyokuphakama:
14 “-150 -160 15” -155 “-165”
16 “-160 -170 17” -165 “-175”
18 “-170-180 21 “-175-185”
26 “-180-190 27.5 “-185-195
Kuze kube ngo-2009, lapho amabhayisikili e-MARMOT groundhog ethuthukisa ibhayisikili lokuqala emhlabeni elingu-27.5-intshi / 650B eWashington, dc, cishe wonke amabhayisikili asezintabeni ayengama-intshi angama-26. Ngoba le modeli inganikeza ukudlala okuphelele ekuphatheni okungcono kakhulu, ukuzinza, ukuphepha nokusebenza kwebhayisikili, kusukela lapho, inguquko entsha yamasondo embonini yamabhayisikili ifike ngokusemthethweni, futhi nemikhiqizo emikhulu ilandele okufanayo ukwakha imoto egcwele usayizi, kanti imoto engu-27.5 “/ 650B egcwele usayizi omncane iye yaba umkhiqizo ojwayelekile emakethe yamabhayisikili [6]. Ngoba isilinganiso somzimba womuntu ngamunye sihlukile, ubude bemilenze nezingalo buhlukile, ngakho-ke ngikufundisa indlela elula nesebenziseka kakhulu yokulinganisa: gqoka izicathulo zakho, ume ngaphesheya kohlaka kushubhu, izinyawo ububanzi behlombe, crotch kanye ithubhu kuhlaka kufanele ibe malunga no-5-6 cm ibanga; Uhlaka lukhulu uma ishubhu elingenhla lisondele noma eduze kwensimbi, futhi lincane uma ishubhu elingenhla likude kakhulu nengwenya. Umgibeli othanda izwe eliwela izwe selizokhetha izincanyana ezimbalwa, i-crotch nomsele kuhlaka lwemoto ngenxa yebanga elingaba amasentimitha ayi-6-10. Lokhu ukuphatha kahle, ukuphepha okuphezulu, ngoba ukuphuma komgwaqo kuyingozi kakhulu, ngakho-ke uzimele ube mncane.
Amafreyimu wokugcina kanzima ahamba kalula, alula futhi ashibhile. Izimoto ezinomsila onzima, njengoba igama liphakamisa, azinazo izinto zokuthwebula ezingemuva, kepha iningi linezimfoloko zangaphambili. Eminyakeni embalwa eyedlule, ukukhetha phakathi kwalaba bobabili kwakulula: abantu babevame ukuthenga ibhayisikili lomsila onzima. Ngokuthuthuka kobuchwepheshe bokuthuthumela, kunzima ukunquma ukuthi uthenge ibhayisikili elinentambo eqinile noma ibhayisikili eligcwele intaba. Yize ibhayisikili eligcwele lokumiswa kwentaba selithuthuke kakhulu, ubuchwepheshe besithuthuthu sezintaba esinzima nabo buyathuthuka. Ukuthi ukhetha i-hardtail noma ibhayisikili lezintaba elimisiwe ngokuphelele kuncike kulokho ozokwenza ngebhayisikili lakho - noma ngabe uzobamba iqhaza emjahweni onqamula izwe, umjaho wezintaba zonke noma umzila wemvelo obushelelezi? Njengomthetho wesithupha, lapho ufuna ukuwela khona ngobuchwepheshe ngokwengeziwe, maningi amathuba okuthi uzodinga ibhayisikili lomsila onzima.
Amabhayisikili asezintabeni zeHardtail alungele indawo engekho emgaqweni, umzila owodwa nomjaho. Ilula, iqina futhi ayibizi kakhulu kunebhayisikili elithusa kakhulu. Ilula ngoba kunezingxenye ezimbalwa kuhlaka, futhi zihlala isikhathi eside ngoba ayinayo i-pivot noma ukumiswa kwangemuva okuzolungiswa. Lokhu kusho ukuthi kubiza kancane ukondla, ngakho-ke kushibhile ukusebenzisa futhi intengo yokuqala yokuthenga iphansi. Ngalezi zizathu, ibhayisikili lomsila onzima kube ukukhetha kwabagijimi abaningi abanqamula izwe. Kungakhathaliseki ukuthi ungumshayeli webhayisikili omusha noma onolwazi, i-hardtail yibhayisikili elihle kakhulu. Eqinisweni, uma uke wagibela ibhayisikili lomsila onzima, cishe uyavuma ukuthi ingakwazi ukuphatha indawo eningi.
* Imfoloko
Imfoloko ingukuqukethwe kobuchwepheshe obuphakeme bezinto zebhayisikili zasentabeni, ibhayisikili elikhuni lezintaba alivamile, ngokuyisisekelo linemfoloko yokushaqeka. Kunezimboni eziningana emhlabeni wonke ezinezimfoloko ezinhle zangaphambili: i-RST, i-SR Suntour, i-DNM, i-RockShox, iMarzocchi, iManitou, i-FOX, i-BOS… Phakathi kwazo, imfoloko yezimboni ezinhlanu zokuqala inemfoloko yemodeli yendawo yonke engaphansi kwe-1000 yuan, ngenkathi lezi ezimbili zokugcina azivamile, futhi intengo iphezulu kakhulu. Noma imfoloko yemodeli yendawo yonke nayo isondele ku-yuan ka-2000, abanikazi bezimoto abasha abakwazi ukuyikhokhela, futhi kunzima ukudlala indima yayo noma ngabe bayayithenga.
Uhlobo lokuphakathi:
(1) imfoloko yokulinganisa: imfoloko ebangeni eliphansi kakhulu, akukho ukumanzisa.
Izici: eshibhile, ama-yuan angama-300 ukuthenga okuhle.
Imfoloko yokumelana nayo: ngemfoloko yokumelana njengento ephakathi, akukho okubampayo.
Izici: Kukhulu ngokwanele kunangaphansi, kepha imfoloko yokuphikisana neminyaka emithathu noma ngaphezulu izoguga, idinga ukushintshwa.
Imfoloko yentwasahlobo kawoyela yenziwe nge-Coil ne-oyili njengokuthambisa okuphakathi.
Izici: ezisindayo, kepha ziqinile. Intwasahlobo inomswakama omningi, izwela impendulo encane yokudlidliza, imvamisa isigamu sonyaka samafutha okugcotshwa kwe-shock, imfoloko kawoyela.
(4) kophayiphothi kawoyela negesi: nge-Air (Air) njenge-rebound medium, ukuthusa uwoyela njengokuncibilikisa.
Izici: ilula kunemfoloko yasentwasahlobo kawoyela, kepha ukuqina kuyancipha. (akukubi kangako, futhi. Izwe eliwela unqamule izwe lilingene ngokwanele.) Dlala umoya njalo ezinyangeni eziyisithupha, isitolo semoto sizonikeza ngokudlala mahhala okuyisilinda somoya, ukuthenga kukodwa nakho, nge-barometer engama-yuan angama-200 noma kunjalo. Inzuzo yokusebenzisa umoya njengesiphakathi ukuthi ilula futhi ivikela isihlakala somgibeli phakathi kwejubane elinqamula izwe, kepha ayizweli kakhulu kunyakaza okuncane.
Ukuhleleka kokusebenza kwemfoloko engaphambili kufanele kube kanjena: lapho uhlangabezana nezingqinamba - imfoloko yangaphambili icindezelwe - ngokweqile - ibuyiselwa kubude bokuqala (ijubane lokuphinda lisebenze lithintwe ukumoshwa) - uhlelo lokubhampa luphelile .
Igama lobuchwepheshe noma lesiNgisi ngemfoloko yangaphambili:
Ukuhamba: ubude bokugcina imfoloko engabucindezela. XC ngo-80-120 - mm. Inqola ne-AM imfoloko engu-130-160mm. Ukwehla kwejubane kufanele kube ngaphezu kwe-180mm.
Ukubuyela emuva: Ukubuyela emuva ngemuva kokuncipha esigxotsheni, yi-medium (i-glue yokumelana, i-Spring, umoya) ukuphindela emuva kubude bangempela bokuhamba, okuyi-Spring half, ngoba ijubane le-Rebound lizothinteka lapho kugcwala uwoyela, ngakho-ke yiba igama lobuchwepheshe .
Ukuncipha kokumelana: isiphethu sasebusika, kushesha kangakanani ukusubuyela emuva, okunqunywa ukumelana. Ijubane eliphezulu lokuzivocavoca, ukuphinda usheshe, kuzokhokhelwa; Ukubuyela emuva kuhamba kancane, uhambo luba lufushane nangaphezulu lapho isithiyo esiqhubekayo sicindezelwa, umuzwa wesandla uyafana nemfoloko kanzima ngaphandle kokuphindeka.
Ukulungiswa Kokubuyiswa: lokhu kuyitimu yezobuchwepheshe futhi imfoloko ngamakhulu ama-yuan abiza kakhulu. Kepha imfoloko ye-Z3 yakudala ye-mazzucci iza nalesi sici; Ngaphezu kwalokho, imfoloko yeRockShox, inqobo nje uma imodeli ene-SL nayo ibhande. Njengoba igama liphakamisa, ukulungisa ijubane lokubuyela emuva. Thatha imfoloko yalo msebenzi, awudingi ukushintsha uwoyela ocacile, ojiyile, ongafinyelela injongo elungisa ukubuyela emuva. Umthelela wokulungiswa kokuphindela emuva ku-off-road - umgwaqo omncane wamatshe, umgwaqo wodaka, udinga ukubuyela emuva ngokushesha; Indlela enamadwala, eyehla kakhulu idinga ukubuyela emuva kancane. I-knob yokulungisa ukubuyela emuva ivame ukuba sohlangothini lwesobunxele lwemfoloko. Umgomo ngukuthi ngemuva kokujikeleza, ungenza umgodi kawoyela ube mncane, futhi wehlise inani lamafutha ngesikhathi seyunithi, wandise isikhathi samafutha, ukufeza inhloso yokubuyela emuva kancane. Sifana nesithuki sosawoti sepulasitiki esinembobo. Ngokuya ngemikhuba yokucabanga kwamaShayina, kulula ukuqonda umthethonqubo wokuqina njengokomthetho wokumelana, ngoba ijubane lokuqina lilawulwa inani lokumelana nophethiloli ngaphakathi nangaphandle.
I-Lockout: lapho ugibela, imfoloko yangaphambili ingakhiywa ngokusebenzisa ifindo elikhethekile. Njengomfoloko onzima, awunampendulo yokumuncwa okuthusayo kunoma isiphi isithiyo. Lokhu kuzonciphisa ingcindezi futhi kwenze kube lula ukukhuphuka amagquma. Kuzophinde futhi konge namandla emigodini emide. Isidlali esijwayelekile asisizi kakhulu futhi kunconywa ukuthi imali ichithwe kwezinye izinto. Kunezakhiwo ezimbili zokukhiya, ukhiye owenziwe nge-mehendi, ukhiye we-damping.
* Uhlelo lokuphamba
Uhlelo lwamabhuleki lubandakanya ukubopha, isibambo sokubopha, umugqa wokubopha.
Amabhayisekili asentabeni asebenzisa izinhlobo ezimbili zamabhuleki: Amabhuleki ama-V namabhuleki e-disc, ngenkathi amabhayisikili ajwayelekile esebenzisa amabhuleki amisiwe ngokungafanele.
I-V brake: amandla akhulu kakhulu, ngoba kungukuqhekeka kwesondo, ngakho-ke isondo kufanele lishintshwe endaweni yalo, futhi kungabi lula ukulamula.
I-Disc brake: uma uqhathanisa ne-V brake, kunzima nangaphezulu ukukhiya ithayi. Lapho ushayela ngesivinini esikhulu, kuyingozi ukukhiya ithayi, okuzoholela ekulahlekeni naseceleni. Intengo ye-Disc brake iyabiza kakhulu, iphuzu elihle licishe libe yi-1000 yuan, i-V brake 400 yuan ingathenga okuhle impela.
Amabhuleki e-disc ahlukaniswe izinhlobo ezimbili: Amabhuleki e-hydraulic disc kanye namabhuleki e-mehendi. Amabhuleki e-hydraulic disc athembela ku-oyili ukucindezela amaphakethe ama-brake ukuze athole amandla amakhulu we-braking. I-Wire disc brake ngamandla eminwe ukuze baphuke, empeleni, basebenzise i-XC ngaphezulu kokwanele.
I-V brake ihlukaniswe yaba yizinhlobo ezimbili: i-hydraulic V brake kanye ne-mechanical V brake, umgomo wesikhumba wamabhuleki kanye nezinhlobo ezimbili ze-disc brake, ngokulandelana. Kepha ingcindezi ye-oyela V ayivamile kakhulu, kulula kakhulu ukufa, ngakho-ke akukho moto, kepha abakwa-09 GIANT ATX850 basebenzise i-oil pressure V brake.
* Uhlelo Lokudlulisela
Uhlelo lokuhambisa lufaka i-disc disc, shaft central, chain kanye ne-flywheel.
Idiski yamazinyo: ebizwa nangokuthi i-disc yamazinyo. Iningi lazo linamagiya ama-3, amanye awo ashintshela ku-2 ngesisindo esincane, kepha amanye awo asebenzisa i-4 CNC, kepha akukuncane okujabulisayo. Imvamisa amadiski ethu angama-44-32-22t, kepha kukhona ama-3 * 10 speed disc discs angama-42-32-24.
I-axis ephakathi nendawo: kunezinhlobo ezintathu zokuhlanganisa i-axis ephakathi nendawo, i-plum hole central axis ne-square hole central axis, ubude kanye nobubanzi bunamazinga ahlukile, kufanele kuthengwe ngokuya nge-disc ehambisanayo yezinyo.
I-Chain: lokhu kuyimpahla engabambeki, i-chain ephukile kuvamile, ukugibela ibanga elide, qiniseka ukuthi uthathe i-yooo enhle yokusekela, hleze umgwaqo we-qinghai-tibet ashen hitchhiking.
I-Flywheel: khetha le. Bangu-8, 24, 9, 27, no-10, 30. I-SRAM inezingu-11. Empeleni, umshayeli ngeke awasebenzise wonke amagiya, futhi usebenzisa igiya elilodwa kuphela u-80% wesikhathi. Leli giya kumele kube elifanele kakhulu ukuphoqelela kanye nokuvama kwonyawo lomshayeli. Ngakho-ke, lapho umshayeli eba namagiya amaningi, kulapho eba namandla ngokunembe kakhudlwana ekukhetheni igiya lakhe. Le moto enejubane elingu-27 inamagiya amathathu ngaphezulu kunaleyo ehamba ngesivinini esingu-24, okwenza umshayeli akwazi ukukhetha okunye. Futhi amagiya amaningi, bushelelezi ushintsho.
Uhlelo lwesivinini olushintshashintshayo lubandakanya ukulawulwa kwesivinini okuguquguqukayo, ukudayela kwangaphambi, ukudayela kwangemuva kanye nomugqa wejubane oguquguqukayo.
Ukudluliselwa, uhlobo olujwayelekile kakhulu lwasekhaya, eyodwa yiShimano (Japan), kanti ezimbili yiSRAM (e-United States).
I-SRAM ingelinye lamaphayona okukhiqizwa kohlelo lokudlulisela. I-Ximano ukuphela komenzi ezintabeni angaqhathanisa ne-SRAM, kanti nemikhiqizo yayo ephezulu engabhekwa njengemisebenzi yezandla. Bobabili bahlala emakethe yaseChina iminyaka eminingi. I-SRAM iphakeme impela ekusebenzeni kwezindleko. Isibonelo, uhlelo lokudlulisa lwe-SRAM X9 lwenzelwe uShimano Deore XT, kepha intengo iphansi kakhulu. Kubalulekile futhi ukuqaphela ukuthi uShimano akahambisani nezinye izingxenye ze-SRAM (ngokwesibonelo, isilinganiso sokudonswa ngomunwe kwe-SRAM ngu-1: 1, ngenkathi uShimano eyi-1: 2.5) futhi kungcono ukungazihlanganisi.
Shintsha: i-cent yizinhlobo ezimbili, ukukhomba ukudayela, i-2 ukuvula, lapho uphendukela ekushintsheni izingobo zomlando, woza ngokushesha okukhulu, abanye abantu banothando lokukhomba ukudayela, ngenxa yomuntu ohlukile. Ukuhanjiswa kukaShimano kuqhutshwa kakhulu ngomunwe, kanti i-SRAM yaziwa ngokuhanjiswa kwayo.
Noma kunjalo unejubane lokushintsha okuphindwe kabili lokulawula, ibhuleki ejika umunwe kanye nophuleka yenziwe yaba yinto ephelele, inzuzo enjalo ukuthi ibe nokuhambisana okuphezulu kakhulu futhi ibe yinhle, ukungafaneleki, uma kwenzeka ukuphuka komunwe kungaphuliwe, kusamele shintsha ndawonye ngokuphelele. Ngaphezu kwalokho, ukusebenza amabhuleki nokushintshwa kwejubane ngasikhathi sinye kunengozi enkulu ecashile kwezokuphepha, futhi uhlelo lokulawula izinto ezimbili seluhoxile emakethe emkhakheni webhayisikili lasentabeni.
Ukudayela kwangaphambili: iya ku-XT ngemali ethe xaxa, i-Alivio ngejubane le-9 ne-Deore ngejubane eli-10 ngemali encane.
Ukudayela emuva: kubaluleke kakhulu kunokudayela kwangaphambili, kuphakanyiswa ukufaka i-guy ebangeni eliphakeme kunalokho okudayela ngaphambili. NjengeShimano SLX, iDeore XT chungechunge, i-SRAM X9, njll, ihlala isikhathi eside. Ngemali encane, thola iShimano Alivio ngejubane le-9 kanye ne-SRAM X5 ngejubane le-9/10.
Ulayini oguquguqukayo oguquguqukayo: mncane kunentambo yokubopha.
Okunamathiselwe: UShimano ulinganiselwe i-XTR, i-Deore XT, i-SLX, i-Deore, i-Alivio, i-Acera, i-Altus, i-Tourney ukusuka phezulu kuya phansi.
I-Saint ne-Zee kuyatholakala futhi emakethe ye-DH, kuyilapho i-SLX ilungele i-AM.
* Amasondo
Amasondo afaka i-rim, i-wire iron, ngaphambili nange-axle engemuva, isondo, isondo elingaphakathi.
Rim: isithuthuthu esisezintabeni kufanele sisebenzise izindondo eziphindwe kabili. Ngenxa yokuthi ungqimba oluphindwe kabili luqinile kunesendlalelo esisodwa, lungamelana novivinyo lwendawo engeyona yokusebenza kwebhayisekili. I-rim ibuye ihlukaniswe: i-cutter rim ne-i-ring.
Inzuzo yendandatho yokusika ukuthi iqinile ngokumelene nomthelela omude, noma ngabe amandla aqine kangakanani, ngeke iveze ukujikeleza okuyindilinga, kuyilapho kulula ukuyiguqula. Iphinda inciphise ukumelana nomoya futhi ilungele abashayeli be-amateur nokuqeqeshwa. Ukungathandeki kusindayo, akulungele ukukhuphuka.
I - ring ukumelana transverse umthelela kunamandla.
I-wire wire (spokes): kukhona ezimbili, okukodwa kuvamile, isigaba sesiphambano siyindilinga; Enye ingxenye yesiphambano iyisicaba, evimbela ukuhudula ngaphambili.
I-Axle: yaziwa nangokuthi isigubhu sezimbali. Nabangani be-disc brake, kufanele bakhethe i-disc brake shaft, ngoba i-disc brake disc ihleliwe kushede le-disc brake; Abangani baka-brake, ungasebenzisa shaft ejwayelekile, uma ufuna ukuthuthukela ku-disc brake, ungafaka i-disc brake shaft.
I-ekseli ihlukaniswe ngo-ekseli le- “perrin” ne-“gear bead”. Kunconywa ukuthenga i-perrin shaft, engashintshwa.
Ithayi langaphandle: libaluleke kakhulu ngoba lithinta ngqo ukulawulwa komgibeli endaweni ethile yomgwaqo. Amaphethini ahlukahlukene okunyathela ahambelana nezindawo ezihlukile zomgwaqo.
Ithayi elincane, linciphisa ukumelana, lishesha ijubane, liqina ngokwengeziwe ifulethi. Ithayi le-Bare, lilungele umgwaqo osimende wedolobha.
Lapho kudlulisa unyawo ngokwengeziwe, kokuphikiswa okukhulu, ijubane lihamba kancane, kuba namandla okushayisana entabeni.
Ishubhu langaphakathi: liyathengiseka.
