8. Gudun tafiya da jan hankali
Ga masu tono masu rarrafe, lokacin tafiya ya kai kusan kashi 10% na jimlar lokacin aiki. Gabaɗaya, masu tonawa suna da kayan tafiye-tafiye guda biyu: babban gudu da ƙarancin gudu. Gudun dual ɗin yana iya haɗuwa da hawan haƙoƙi da aikin tafiye-tafiye na ƙasa lebur.
(1) Ƙarfin jujjuyawar yana nufin ƙarfin ja da ke kwance da ake samu lokacin da mai tono yana tafiya a kwance. Babban abubuwan da ke haifar da tasiri sun haɗa da ƙaura mai ƙarancin gudu na injin tafiya, matsa lamba na aiki, diamita na farar tuƙi, nauyin injin, da dai sauransu. Masu haƙawa gabaɗaya suna da ƙarfin juzu'i, wanda gabaɗaya ya kai 0.7 zuwa 0.85 nauyin injin.
(2) Gudun tafiye-tafiye yana nufin matsakaicin saurin tafiye-tafiye na tono yayin tafiya akan daidaitaccen ƙasa. Gudun tafiye-tafiyen na'urorin hayar ruwa gabaɗaya baya wuce 6km/h. Masu tono na'ura mai ɗaukar hoto na Crawler ba su dace da tafiya mai nisa ba. Gudun tafiye-tafiye da karfin juzu'i suna nuna iyawa da iya tafiya na tono.
9. Iya hawan hawa
Ƙarfin hawan mai tona yana nufin iya hawa, saukowa, ko tsayawa a kan tudu mai faɗi. Akwai hanyoyi guda biyu don bayyana shi: kwana da kaso: (1) Matsakaicin hawan θ gabaɗaya 35° ne. (2) Kashi na tebur tanθ = b/a, gabaɗaya 70%. Ma'anar microcomputer gaba ɗaya shine 30 ° ko 58%.
