Plaub hom log tsheb tshwj xeeb

Muaj feem ntau plaub qhov system nyob rau hauv kev ua lag luam, Askiv system, German system, metric system thiab Asmeskas system. Peb yuav piav qhia luv luv txog plaub txoj kab ke hauv qab no. Cov kev qhia tshwj xeeb tshaj plaws tau lees paub los ntawm British lub teb chaws nyob hauv vassal yav dhau los, thiab chav tsev nyob rau hauv nti. Piv txwv li, 4.00 H 18 4PR txhais tau hais tias 4 nti dav, haum rau qhov nrawm qis dua 210KM / H, lub log ntug txoj kab uas hla yog 18 ntiv, thiab 4 xaim txheej muaj zog. Hauv cov metric system, cov lus piav qhia ntawm cov yam ntxwv ntawm lub log tau ua tiav ntau dua. Nws zoo sib xws rau German txheej txheem, tab sis thim tawm" -" kev ua haujlwm siab txo qis lub cim, thiab hloov nws nrog lo lus" R" txhawm rau qhia cov log tsheb radial, xws li FZR400 Lub log tom ntej yog 140 / 60R18 64H, qhov twg R ntawm R18 txhais tau hais tias lub log tsheb yog lub log tsheb radial. Cov lus qhia tshwj xeeb ntawm German system zoo ib yam li" metric system." Ntxiv nrog rau qhov dav ntawm lub log qhia hauv millimetres, cov nam piv ntawm cov log kuj tseem nce ntxiv. Lub taub loj ntawm lub log tsheb tseem nyob rau hauv nti, thiab muaj cov load index thiab cov paib nrawm ntsuas tom qab txoj kab uas hla puab. Xws li: 140 (lub log dav 140MM) \ 70 (sib piv lub cev tsis sib haum 70%) - (lub log tsheb tsis tshua muaj zog) 18 (lub log loj 18 ntiv taw) 66 (load Performance 66) H (ceev kos npe 210KM / H lossis tsawg dua).
