纵向通过直径

I've seen the text too, but seem like inappropriate. Then again, I don't know anything about automobiles. Good luck!

纵向通过直径 could perhaps be "longitudinal passing diameter"

The diagram is extremely useful, thank you. I have seen 纵向通过半径 translated as "longitudinal passibility radius", but now need to consider the best English term for this.

Dont have enough idea, but only too much difference between 纵向通过直径 and curb-to-curb turning diameter

21:59 Feb 23, 2009 

I have just found this on the Ford website:

"Turning diameter
The diameter within which a vehicle can turn completely in a circle as measured in one of two ways:


The curb-to-curb turning diameter is made at the outside of the outer front tire
The wall-to-wall turning diameter is measured from the point of most extreme front-end overhang, generally the bumper."

Could perhaps 最小转弯直径 be wall-to-wall turning diameter and 纵向通过直径 be curb-to-curb turning diameter?

Yes, Hamish. I think I'll have to see if my customer can help with this.

Thanks, Adsion (and sorry for spelling your name incorrectly above!). I will try to get some clarification from my client on this. There is no mention of this anywhere else in my document, so I have nothing in the text to go on.

I agree with Adsion. None of the answers below are in the literature, and it could well be a mistake

13 m has obviously little to do with clearance, but more with diameter of the circumscribed circle for pass in lengthwise (without any steering). 纵向通过角, maybe, but why with (m)? You are recommended to refer to the customer for some explanation thereon.

Many thanks Adison, Joyce, Hamish and Shirley for your help. I am still stuck, however. Here are the figures that go with the terms:

最小离地间隙 170
最小转弯直径(m) 13.8
纵向通过直径(m) 13
接近角（度） 19
离去角（度） 18

I am assuming 纵向通过 refers to ramp breakover, but I only know ramp breakover angle. With the 纵向通过直径 being 13m, this isn't to do with clearance. Should, perhaps, this be 纵向通过角（度）instead of 纵向通过直径(m) ?
