Kodi ndingawonjezere camber kumawilo anga?
Zimakhala zofala kwambiri kuwona magalimoto "osinthidwa" (kapena, kawirikawiri, magalimoto onyamula) okhala ndi ma camber mopitilira muyeso - mwa kuyankhula kwina, okhala ndi mawilo ndi matayala omwe amapendekeka mowoneka bwino poyerekeza ndi ofukula. Eni ake ena angadabwe ngati kusintha camber motere ndi lingaliro labwino, kapena akudziwa kale kuti akufuna kutero koma akufuna kuwonetsetsa kuti ndi otetezeka.
Kuti mudziwe ngati kusintha camber yagalimoto ndi lingaliro labwino, ndikofunikira kumvetsetsa kaye kuti camber ndi chiyani komanso zomwe amachita. Camber ndi mawu omwe amagwiritsidwa ntchito kutanthauza kupatuka kwa matayala agalimoto kuchokera kuchongoka akawonedwa kutsogolo kapena kumbuyo. Pamene nsonga za matayala zili pafupi ndi pakati pa galimoto kusiyana ndi pansi, izi zimatchedwa camber negative; mosiyana, kumene vertices amapendekeka kunja, amatchedwa positive kink. Mbali ya camber imayesedwa mu madigiri, zabwino kapena zoipa, kuchokera kumtunda. Ndikofunika kuzindikira kuti camber imayesedwa pamene galimoto ikupuma, koma ngodya imatha kusintha pamene ikudutsa.
Chinthu choyamba kumvetsetsa za makonzedwe oyenera a camber ndikuti camber ofukula - madigiri a zero - nthawi zonse imakhala yabwinoko ngati ingatheke. Tayala likakhala loimirira, kuponda kwake kumakhazikika pamsewu, zomwe zikutanthauza kuti mphamvu yothamanga yofunikira kuti ifulumire, kutsika, ndi kutembenuka imakula. Kuonjezera apo, tayala lomwe lili mwachindunji pamtunda silidzavala mofulumira ngati lopendekeka, choncho katunduyo amakhala mkati kapena kunja kokha.
Koma ngati ofukula ndi bwino, n'chifukwa chiyani timafunika kusintha camber ndipo n'chifukwa chiyani tingathe kusintha china chilichonse osati ofukula? Yankho ndiloti galimoto ikatembenuka, matayala a kunja kwa ngodya amakhala ndi chizolowezi chachibadwa chotsamira kunja (positive camber), zomwe zingathe kuchepetsa kwambiri luso la ngodya mwa kuchititsa kuti tayala liziyenda pamphepete mwa kunja; kupanga kupendekera kwamkati (negative camber) ya kuyimitsidwa pamene galimoto yapumula kungathe kubweza kupendekera kwakunja komwe kumapezeka pakuyimitsidwa. (Tayala lamkati limatsamira kwina ndipo mwalingaliro kuti camber yabwino ingakhale yabwino kwa ilo, koma sitingathe kusintha zonse ziwiri ndipo tayala lakunja ndilofunika kwambiri.) Mapangidwe a camber a wopanga ndi kusagwirizana pakati pa zero camber (oima), yomwe Ndikwabwino kuthamangitsa mizere yowongoka ndi braking, ndi camber negative, zomwe zimathandizira magwiridwe antchito a ngodya.
Kodi chimachitika ndi chiyani pamene camber isintha kupyola zomwe wopanga amalimbikitsa? Nthawi zambiri anthu akaganiza zosintha camber, amaganiza zowonjezera camber kapena kupendekeka kwamkati. Kumbali ina, kuwonjezera camber yolakwika kumatha kukulitsa mphamvu yokhotakhota ndikuwononga mphamvu ya braking (ndi kuvala kwa matayala), ndipo kusintha kochepa kwambiri pankhaniyi - digiri kapena kuchepera - kungakhale bwino. Komabe, mbali zonse za magwiridwe antchito zimakhala zovuta kwambiri. Zoyipa kwambiri (kapena zabwino, ngakhale izi sizodziwika) zingathandize kukwaniritsa mawonekedwe ena kapena kukonza zosintha zina monga ma airbags, koma magalimoto omwe ali ndi zosintha zotere sangakhale otetezeka kuyendetsa chifukwa sangathe kuyenda. ananyema bwino.
Okonza magalimoto othamanga amasankha camber yoyenera kuyendetsa magalimoto awo; nthawi zambiri izi zitha kukhala zosokoneza kuposa momwe zingakhalire zoyenera pamagalimoto apamsewu, koma zokonda zina ndizotheka. (Mwachitsanzo, magalimoto othamanga okhala ndi mayendedwe ozungulira omwe amangotembenukira kunjira imodzi nthawi zambiri amakhala ndi ma camber oyipa mbali imodzi ndi camber yabwino mbali inayo.) Mvetsetsani kuti matayala adzawonjezeka.
Koma pagalimoto yamsewu, chitetezo chiyenera kukhala chodetsa nkhawa kwambiri, ndipo kusiya mphamvu zambiri zoyimitsa panjira yolowera m'mphepete sikwabwino. Kusintha kwa Camber mkati kapena pafupi kwambiri ndi kulolerana kovomerezeka kwa wopanga kuyenera kuonedwa kuti ndi kotetezeka, koma kupitilira izi (ndipo pano ngakhale digiri imodzi ndikusintha kwakukulu) magwiridwe antchito a braking amatha kutsika mwachangu ndi lingaliro loyipa. Ena ngati mawonekedwe ndipo ena amaganiza kuti phindu la ngodya ndilofunika, koma m'galimoto iliyonse yomwe idzayendetsedwe m'misewu, camber yoopsa si yotetezeka.
Chidziwitso china chokhudza magalimoto omwe adatsitsidwa kwambiri: nthawi zina magalimotowa amakhala ndi vuto lalikulu, osati chifukwa choti mwiniwakeyo adafuna, koma chifukwa chotsitsa chasintha camber. Ndikofunika kukumbukira kuti kusintha kulikonse koyimitsidwa kungakhudze chitetezo; pakakhala kutsika komwe kumayambitsa camber mochulukira, kutsitsa komweko sikungakhale koopsa, koma chotsatiracho chingakhale chowopsa.
