Don sanya shi a sauƙaƙe, yawancin direbobin manyan motoci sun san cewa ƙaramin adadin gudu na baya yana nufin ƙaramin ƙarfin hawan hawa, saurin sauri da ƙarancin amfani da mai; babban rabo gudun axle na baya yana nufin karfi hawan hawan, jinkirin gudu da yawan man fetur.
Amma me ya sa? Muna bukatar mu san ba kawai abubuwan da suka faru ba amma har da dalilan da ke tattare da su. Yau, bari mu yi magana da direban abokai game da gudun rabo na raya axle na manyan motoci!
Matsakaicin saurin axle na baya sunan kowa ne kawai. Sunan ilimi shine babban rabo na raguwa, wanda shine rabon gear na babban mai ragewa a cikin tuƙin motar. Zai iya rage gudu a kan tudun tuƙi kuma yana ƙara ƙarfin wuta. Misali, idan ma'aunin gudu na baya na babbar mota ya kai 3.727, to idan gudun mashin din ya kasance 3.727 r/s (juyin juyi a sakan daya), za a rage shi zuwa 1r/s (juyin juyi a sakan daya).
Lokacin da muka ce motar da ke da girman juzu'i mai girma na baya ya fi ƙarfi, ko motar da ke da ƙananan saurin axle na baya ya fi sauri, dole ne mu kwatanta nau'ikan iri ɗaya.

Me yasa manyan motocin da ke da ƙaramar saurin gatari na baya suke gudu da sauri?
Ba tare da la'akari da abubuwan waje kamar kaya ba, juriya na iska, juriya mai tsayi, da dai sauransu, kuma kawai la'akari da rabon watsawa, za mu iya cire saurin abin hawa ta hanyar dabara:
Gudun abin hawa = 0.377 × (gudun fitowar injin × radius mai jujjuyawa)
Daga cikin su, 0.377 shine ƙayyadadden ƙima.
Misali, idan nau'ikan motocin haske iri ɗaya ne motar A da haske B, an sanye su da tayoyin radial 7.50R16, Wanliyang WLY6T120 watsawa ta hannu, tare da gears gaba 6 da injin juyawa guda ɗaya, mafi girman gudu shine overdrive, gear. Rabo shine 0.78, rabon gudun axle na baya na motar haske A shine 3.727, kuma ƙimar saurin axle na motar haske B shine 4.33.
Sannan idan akwatin gear ya kasance a cikin mafi girman kaya kuma saurin injin ɗin ya kai 2000rpm, bisa ga tsarin da ke sama, muna ƙididdige saurin motar A da B bi da bi. Radius mai jujjuyawa na taya 7.50R16 yana da kusan mita 0.3822 (ana iya samun radius na jujjuyawar tayoyi na ƙayyadaddun bayanai daban-daban bisa ga sigogin taya. Don sauƙaƙe sakamakon da aka nakalto a nan kai tsaye, wannan radius na mirgina yana da kewayon kuskure.
Gudun motar haske A = 0.377 × (2000 × 0.3822) / (0.78 × 3.727) = 99.13 (km/h);
Motar Haske B gudun = 0.377 × (2000 × 0.3822) / (0.78 × 4.33) = 85.33 (km/h);
Don irin wannan samfurin, lokacin da ingin ya kasance 2000rpm, ana iya fahimtar cewa saurin motar haske A tare da ƙananan gudun axle na baya ya kai 99.13km / h, kuma gudun motar haske B tare da babban axle na baya. Matsakaicin gudun shine 85.33km/h. Saboda haka, abin hawa tare da ƙaramin adadin saurin axle na baya yana tafiya da sauri kuma yana da ingantaccen mai.
Me yasa manyan motocin da ke da babban rabon gudu na baya suna da karfin hawan hawan?
Ƙarfin hawan hawan yana nufin cewa motar tana da ƙarfin tuƙi. Ƙididdigar ƙididdiga don ƙarfin tuƙi na manyan motoci shine:
Ƙarfin tuƙi = (injin fitarwa karfin juyi × rabon kaya × rabon mai rage ƙarshe × ingancin watsa injin) / radius dabaran
Ga motar haske A da babbar motar B da ke sama, radius na taya 7.50R16 yana da kusan 0.3937m (radius na taya daban-daban kuma ana iya samun su bisa la'akari da sigogin taya. Don sauƙi, an nakalto sakamakon kai tsaye a nan.
Idan kuna sha'awar, za mu gabatar da shi dalla-dalla daga baya). Idan motar wuta A da babbar B suna cikin gear farko kuma ƙarfin fitar da injin ɗin ya kai Nm 450, muna ƙididdige ƙarfin tuƙi da motar haske A da babbar motar B ta samu a wannan lokacin:
Motar Haske A ƙarfin tuƙi = (450×6.32X3.72X0.98)/0.3937=26384.55 (Newtons)
Motar Haske B = (450×6.32X4.33X0.98)/0.3937=30653.36 (Newton)
Lokacin da injin ya kasance a cikin 1st gear kuma ƙarfin fitar da injin ya kasance 450 Nm, ƙarfin tuƙi da aka samu ta hanyar motar haske A shine 26384.55 Newtons, wanda galibi yana magana game da 2692 kilogiram (kg) na turawa (1 kg-force = 9.8 Newtons); Ƙarfin tuƙi da motar haske B ta samu shine 30653.36 Newtons, wanda ke magana game da kilogiram 3128 (kg) na turawa (1 kg-force = 9.8 Newtons). Babu shakka, babbar motar B tare da mafi girman rabon axle na baya yana samun ƙarfin tuƙi, kuma a zahiri yana da ƙarfin hawan hawa.
Abin da ke sama yana da ban sha'awa mai ban sha'awa. Don sanya shi a hanya mai haske, idan aka kwatanta motar da mutum, saurin gudu na baya yana dan kama da ƙasusuwan ƙafa. Idan rabon gudun axle na baya yana da ƙananan, motar na iya gudu da sauri tare da nauyi mai sauƙi kuma mitar gudu tana da girma; idan rabon gudun axle na baya yana da girma, motar zata iya tafiya gaba da nauyi mai nauyi kuma mitar gudu tayi ƙasa.
Daga binciken da aka yi a sama, za a iya ganin cewa saurin axle na baya yana da ƙananan, ƙarfin hawan yana da ƙananan, kuma yawan man fetur ya ragu; Matsakaicin saurin axle na baya yana da girma, ƙarfin hawan yana da ƙarfi, saurin yana jinkirin, kuma yawan man fetur yana da yawa.
