Kusankha Geometry Yoyenera ya MTB Frame

Munkhani iyi yaukadaulo ya geometry yanjinga yamapiri, tafotokoza gawo lililonse la C'est pas socier kuti likhale lomveka bwino komanso lodziwitsa zambiri ngati Jamie. Mutha kutidziwitsa m'mawu omwe ali kumapeto kwa nkhaniyi ngati tamaliza ntchito yathu!

Mukuyang'ana ATV yatsopano?

Pitani ku sitolo yomwe mumakonda kuti muyese.

Inde, tikukulimbikitsani kuti muyese mitundu ingapo mpaka mutapeza yanu - chabwino, pakalipano, chifukwa zokonda zanu, machitidwe anu, ndi morphology yanu imasintha zaka zambiri.

Chifukwa chake tidati, mumayesa njinga zamapiri. Kukula komweko, mtundu womwewo wa njinga yamapiri, koma simumva chimodzimodzi, simukumva bwino pa onsewo.

Chifukwa chake? Bicycle geometry.

Kodi Mountain Bike Geometry ndi chiyani?

ATV ili ndi zigawo zitatu zazikulu:

• chimango;
• mphanda;
• mawilo.

(Mukawonjezera chishalo, zogwirizira, ma pedals, ndi nkhani yotonthoza komanso yothandiza.)

Pakali pano, aliyense akuyang'ana? Chabwino, tiyeni tipitilize.

Chabwino, geometry ya quad yanu ndi kuphatikiza zinthu zitatuzi ndi chilichonse chomwe chimabwera ndi iwo (utali wa chubu, ngodya, ndi zina).

Kapangidwe kanjinga yanu (momwemo geometry yake) imakhudza magawo ambiri, makamaka, momwe mumakwerera.

Ngakhale kuti si yankho ku matenda anu onse, geometry yomwe siinagwirizane ndi morphology yanu imathanso kuyambitsa kusapeza bwino, komwe kumakwiyitsa kwambiri mukamayenda nthawi yayitali. Ndizotheka kudziwa pang'ono za geometry yosasinthika bwino (ulalo wa Momwe Mungasankhire Kukula Kwa MTB Koyenera ndi Kusintha MTB Kuti Mupewe Kupweteka kwa Knee), koma zosinthazi sizidzalowa m'malo mwa MTB yamtundu wa thupi lanu komanso kukwera kwanu. kalembedwe.

Kumvetsetsa Mountain Bike Geometry

Chimango cha njinga yamapiri

Timayesetsa kuchepetsa kukula kwa chimango mpaka kutalika kwa chubu chake chapamwamba. Ndipotu, ndi ngodya ya chubu ya mpando yomwe imatsimikizira kukula kwa chimango.

Samalani zinthu zitatu:

• mtunda wopingasa pakati pa crank axis ndi foloko (kufika);
• mtunda woyima pakati pa crank axis ndi foloko (stack);
• mtunda wopingasa pakati pa crank axis ndi gudumu lakumbuyo (kukhazikika kwa unyolo).

Ndi chifukwa cha deta iyi kuti mudzasintha tsinde, choncho, mudziwe malo anu panjinga.

Chimango cha njinga yamapiri ndi mphanda

Tsopano tiyeni tiwone mbali ya mphanda ndi momwe imalumikizirana ndi chimango. Chifukwa, monga momwe zilili ndi maphikidwe aliwonse, sizinthu zokhazokha zokhazokha zomwe zimafunikira, komanso momwe zimagawidwira ndikusakanikirana.

Kuti timvetsetse momwe njinga zamapiri zimayendera, tiwonanso zambiri zitatu:

• mtunda pakati pa crank axis ndi kutsogolo gudumu olamulira;
• mtunda pakati pa gudumu lakutsogolo ndi gudumu lakumbuyo (wheelbase);
• angle ya foloko ndi fork offset (wodzigudubuza).

Chodzigudubuza chokhazikika panjinga yamapiri

Tiwulongosolera pang’ono nkhani imeneyi ya kusaka malasha.

M'malo mwake, izi zikupatsirani lingaliro la kukana kwa ATV pakusintha kolowera ndipo chifukwa chake mphamvu yomwe muyenera kugwiritsa ntchito kuti muchite zimenezo.

Zing'onozing'ono zowongolera ndi ngodya ya caster, ATV imakhala yokhazikika, koma ndizovuta kwambiri kusintha njira. Choncho, cockpit ayenera kulabadira ndi wamphamvu: ndiye ife kukhazikitsa yochepa tsinde ndi lonse chogwirira.

Mphamvu ya geometry ya njinga zamapiri pakugwira

Ndife pano, ndipo mumvetsetsa chifukwa chake tidayenera kuchita kanthanthidwe kakang'ono aka.

Mukuyang'ana chiyani kuti muwongolere ATV mosavuta? Kukhazikika ndi kusuntha ndi zinthu ziwiri zomwe, kwenikweni, zotsutsana. Ndizovuta kukhala ndi ATV yomwe ili yokhazikika komanso yothamanga kwambiri. Izi sizingatheke mwakuthupi, ndipo geometry ikufotokoza izi.

Mukakulitsa mtunda wowonekera pamwambapa, mumawonjezera kukhazikika kwa ATV. Ngati mukuyang'ana njinga yoyendetsa bwino kwambiri kuposa china chilichonse, mufupikitsa mtunda umenewo.

Ndichindunji, sichoncho?

Koma zimakhala zovuta kwambiri, chifukwa pazinthu zosiyanasiyana, kufika, stack, wheelbase, tilt angle, ndi zina zotero. Choncho, m'pofunika kusamala ndi kusankha kukula ndi kulabadira zofunika geometry. Pa geometry yofanana, pamagiredi ena idzakhala chilembo M, ndipo kwa ena idzakhala L.

Mumadziwa bwanji ngati mukufuna kukhazikika kapena kulimba mtima?

Zimatengera liwiro lanu komanso mtundu wa maphunziro omwe mukutsatira.

Ngati mukufuna kuyendetsa makilomita motsatira unyolo ndikuyendetsa pa liwiro la mphezi, choyamba muyenera kuyesetsa kukhazikika. Kumbali ina, pa liwiro lotsika, timafunikira njinga yamapiri yothamanga.

Kodi ndinu watsopano kumaphunziro aukadaulo? Sankhani ATV yokhala ndi wheelbase yayikulu komanso ngodya yayikulu yowongolera. Idzakhala yosasunthika pa liwiro lachangu komanso yosunthika m'mapiri kapena m'zigwa.

Mosiyana, kodi mumakonda maphunziro aukadaulo? Ngodya ya chodzigudubuza iyenera kukhala yayikulu kuti ipangitse kukana posintha njira. Zikumveka zotsutsana, koma siziri choncho. Akamasaka molimba, woyendetsa ndegeyo amayang'anira malo ake osati pa loko yowongolera. Wheelbase ya ATV yanu iyenera kukhala yayifupi kuti itembenuke mwachangu komanso mosavuta.

Ndi m'gulu lomalizali kuti tidzapeza njinga mapiri osewera. Izi ndi njinga zakale zomwe zimafuna luso labwino loyendetsa galimoto chifukwa wokwerayo amayenera kugwira ntchito mwakhama kuti aike malo awo a mphamvu yokoka ndikutseka chiwongolero.

Masiku ano opanga akuyang'ana kuti akhazikitse geometry kuti apereke njinga zamapiri zosunthika. Wheelbase ndi yayitali mokwanira ndipo kuthamangitsidwa ndikwapamwamba kwa njinga zachangu zothamanga kwambiri. Malo oyendetsa ndege omwe ali pakati amalola kuti asamayendetse bwino kwambiri, koma pamafunika kuwerenga bwino pansi, kuyembekezera mwachidwi, ndi kuyendetsa mwadala.
