How does a tractor define a "fast bridge" or a "slow bridge"?
Auman ah, to see the door of Transformers, running fast is suitable for highway, bridge, load less than 60tStanding on a slow bridge, you can overload, climb, pull a 100t, no problem
Generally see speed ratio, speed ratio, the better the car speed! No speed bridge, this said, such as half axle bridge than the wheel bridge in the same configuration, the speed is faster! Different bridges are used for different road conditions and different loads!!
Influence of vehicle speed by the rear axle and rear axle gearbox decided bigger, rear axle ratio the smaller the speed will be faster, more than the slower speed, such as 3.73 3.92. or 4.11, the ratio of the speed quickly, 4.38 belong to the national roaming model can speed climbing, climbing speed ratio is too small boring
