Kusarudza iyo Yakarurama Geometry yeMTB Frame

Muchinyorwa chino chehunyanzvi chegomo bhasikoro geometry, takafukidza chikamu chese cheC'est pas sorcier kuti chive chakajeka uye chinodzidzisa saJamie. Unogona kutizivisa mune zvakataurwa pakupera kwechinyorwa kana isu tapedza basa redu!

Kutsvaga ATV itsva?

Enda kuchitoro chako chaunofarira kuti uedze.

Hongu, tinokukurudzira kuti uedze mabhureki mashoma kusvika wawana yako - zvakanaka, ikozvino, nekuti zvaunofarira, maitiro ako, uye morphology yako inoshanduka nekufamba kwemakore.

Saka takati, iwe edza mamwe mabhasikoro emakomo. Saizi yakafanana, mhando yebhasikoro regomo, asi iwe haunzwe zvakafanana, haunzwe wakasununguka pazviri zvese.

Chikonzero chacho? Bhasikoro geometry.

Chii chinonzi Mountain Bike Geometry?

Iyo ATV ine zvikamu zvitatu zvikuru:

• frame ;
• fork;
• mavhiri.

(Mushure mekuwedzera chigaro, mahandbars, pedals, inyaya yekunyaradza uye kuita.)

Panguva ino, munhu wose ari kuona? Zvakanaka, ngatienderere mberi.

Zvakanaka, iyo geometry yequad yako musanganiswa wezvinhu zvitatu izvi uye zvese zvinouya nazvo (tubhu kureba, makona, nezvimwewo).

Iyo yakazara dhizaini yebhasikoro rako (saka geometry yayo) inopesvedzera akawanda paramita uye, kunyanya, yako yekutasva.

Kunyange isiri mhinduro kuzvirwere zvako zvese, geometry isina kuchinjirwa kune yako morphology inogona zvakare kukonzera kusagadzikana kwakapfava, uko kunowedzera kushungurudza mukati mekufamba kwenguva refu. Zvinogoneka kubata zvishoma neiyo isina kunyatso kugadziridzwa geometry (link kune Maitiro Ekusarudza Iyo Yakarurama MTB Saizi uye Rongedza MTB Kuti Udzivise Knee Marwadzo), asi izvi zvigadziriso hazvizombofa zvakatsiva MTB yakakwana yerudzi rwemuviri wako uye kukwira kwako. style.

Kunzwisisa Mountain Bike Geometry

Gomo bhasikoro furemu

Tinoedza kuderedza ukuru hwechimiro kusvika pakureba kwechubhu yayo yepamusoro. Muchokwadi, ikona yechubhu yechigaro inosarudza ukuru hwefuremu.

Tarisa pazvinhu zvitatu:

• chinhambwe chakatwasuka pakati pe crank axis uye forogo axis (svika);
• chinhambwe chakamira pakati peiyo crank axis uye forogo axis (stack);
• chinhambwe chakachinjika pakati peakisi yecrank neaseri yevhiri rekumashure (cheni inogara).

Iko kuvonga kune iyi data kuti iwe unozogadzirisa hunde uye, saka, sarudza chinzvimbo chako pabhasikoro.

Gomo bhasikoro furemu neforogo

Zvino ngatitarisei kudivi reforogo uye kuti rinobatana sei kune furemu. Nokuti, sezvakangoita chero kamukira, haisi iyo chete yemhando yezvigadzirwa zvakakosha, asiwo nzira iyo inoparadzirwa uye yakasanganiswa.

Kuti tinzwisise maitiro ebhasikoro remakomo, isu tichatarisawo matatu data:

• chinhambwe pakati peakisi yecrank neakisi yevhiri remberi;
• chinhambwe chiri pakati peekisero yevhiri remberi neesero yevhiri rekumashure (wheelbase);
• forogo angle uye forogo offset (roller angle).

Roller angle yekugadzikana kwebhasikoro regomo

Tichajekesa nyaya iyi yekuvhima marasha zvishoma.

Muchokwadi, izvi zvinokupa iwe pfungwa yekuramba kweATV kushandura nzira uye nekudaro simba rauchazo shandisa kuti uite kudaro.

Iyo idiki iyo inotungamira kona uye caster angle, iyo yakanyanya kugadzikana iyo ATV, asi zvakanyanya kuoma zvakanyanya kuchinja nzira. Nokudaro, cockpit inofanira kuva inopindura uye ine simba: ipapo tichaisa chidimbu chipfupi uye chibatiso chakafara.

Kupesvedzera kwegomo bhasikoro geometry pakubata

Tiri pano, uye iwe uchanzwisisa kuti sei taifanira kuita iyi dzidziso diki yekutenderera.

Chii chauri kutsvaga kudzora nyore ATV? Kugadzikana uye maneuverability zvinhu zviviri izvo, chaizvoizvo, zvakapesana. Zvakaoma kuve neATV iyo yakagadzikana zvakanyanya uye inomhanya kwazvo. Izvi hazvigoneke mumuviri, uye geometry inotsanangura izvi.

Kuwedzera kwaunoita madaro anoonekwa pamusoro, ndipo paunowedzera kugadzikana kweATV. Kana iwe uchitsvaga bhasikoro rinogoneka kupfuura zvese, unopfupisa iwo madaro.

Zvakanyanya kujeka, handizvo here?

Asi zvinotowedzera kunetsa, nekuti kune akasiyana mhando, kusvika, stack, wheelbase, tilt angle, nezvimwe zvinogona kusiyana zvakanyanya kune yakaenzana furemu saizi (seM kana L). Saka, zvinodikanwa kuchenjerera nesarudzo yehukuru uye teerera kune inodiwa geometry. Kune anenge akaenzana geometry, kune mamwe mamakisi richava vara M, uye kune vamwe richave L.

Iwe unoziva sei kana iwe uchida kumwe kugadzikana kana agility?

Zvinoenderana nekumhanya kwako uye rudzi rwekosi yauri kutevera.

Kana iwe uchida kutyaira makiromita uchitevedza cheni uye uchityaira nekumhanya kwemheni, iwe tanga waedza kugadzikana. Kune rumwe rutivi, pakumhanya kwakaderera, tinoda bhasikoro regomo rinokurumidza.

Uri mutsva kuzvidzidzo zvehunyanzvi? Sarudza ATV ine vhiribhesi hombe uye hombe yekutungamirira. Ichave yakagadzikana nekumhanya nekukurumidza uye inofambiswa mumakomo kana mapani.

Zvakasiyana, iwe unoda tekinoroji makosi? Iyo angle ye roller inofanirwa kuve yakakura kugadzira kuramba kana uchichinja nzira. Zvinoita sezvinopesana, asi hazvisizvo chaizvo. Paunenge uchivhima zvakasimba, mutyairi wendege achashanda panzvimbo yake kwete pakiyi yekutungamirira. Iyo wheelbase yeATV yako inofanirwa kuve ipfupi kuitira kutendeuka nekukurumidza uye nyore.

Muchikamu chino chekupedzisira tichawana mabhasikoro emakomo evatambi. Aya mabhasikoro echikuru anoda hunyanzvi hwekuita nhanho yekutyaira nekuti mutasvi anofanirwa kushanda nesimba kuti aise nzvimbo yavo yegiravhiti uye kukiya chidhiraivho.

Vagadziri nhasi vari kutarisa kumisikidza geometry kuitira kuti vape akawanda emakomo mabhasikoro. Iyo wheelbase yakareba zvakaringana uye kudzingirira kwakakwira kune mabhasikoro anoshanda nekumhanya mhanya. Nzvimbo yepakati pemutyairi inobvumira kushomeka kweacrobatic piloting, asi inoda kuverenga kwakanaka kwepasi, kutarisira kwakanaka, uye kutyaira zvine chinangwa.
