 Chinese term or phrase: 纵向通过直径 I have a list of vehicle specifications: 最小离地间隙 最小转弯直径(m) 纵向通过直径(m) 接近角（度） 离去角（度） I don't understand what 纵向通过直径refers to. I know 纵向通过角 to be ramp breakover angle, but I don't know how to translate 纵向通过直径. Any help would be much appreciated.

 lengthwise/longitudinal (direction) /straight pass-though diameter Explanation:纵向通过直径 应该是指车辆正常行驶（不转弯）时所通过的最大截面的外接圆的最大直径。没找到相应参考，但感觉十有八九是指这个，相应翻译仅供参考或润色。 上面写得挺乱，可能翻译整理如下： 1）lengthwise/longitudinal direction pass-though diameter 2）lengthwise/longitudinal pass-though diameter 3）straight pass-though diameter ......--------------------------------------------------Note added at 6 days (2009-03-02 13:20:19 GMT) Post-grading--------------------------------------------------You are welcome, and thanks for your info., Beth:-)

Ramp breakover clearance

Explanation:
There isn't much in the literature for this. There is an excellent diagram of the ramp breakover angle at http://www.carlist.com/autoglossary/autoglossary_96.html and the only way I can understand 直径 in this context is as the distance between the underside of the car and the ground.

Example sentence(s):
• Adequate ground clearance, approach and departure angles and ramp breakover clearance
