How to distinguish the speed of the rear driving axle of the dump truck
Under certain driving conditions, the smaller the speed ratio of the powertrain, the higher the fuel economy of the car, so the car's economic driving is in the high-grade. In order to driving at high speed in good road conditions, the car device within the transmission ratio is less than 1 of the overdrive, in the same speed, hang overdrive can make the engine speed is relatively low, relatively lower fuel consumption
Speed ratio refers to the gear ratio of the main reducer in the automobile drive axle. It is equal to the rotation angle of the transmission shaft. The speed of the rotation speed of the axle is equal to the ratio of the speed of the axle.
The transmission ratio of the transmission system includes the transmission ratio of each gear to the main reducer, and the drive of a small speed ratio in the good road can improve the fuel economy of the car. However, many objects on the car have a "tipping point" problem, which goes too far into the opposite direction. The main reducer ratio is the same, too small will cause low power quality, but will make the automobile fuel economy is bad, so the general design of the reducer transmission ratio has a range that is directly linked to file or acceleration slope for large power reserve
After the first four, the eight is the car with eight wheels on the front of the four wheelsThe single bridge is the rear of the car. There is only one rear axle. The rear axle must be the driving axle. Shuangqiao refers to two behind the bridge, bridge and bridge, after the bridge is driving bridge can also be moving with the bridge, bridge is a driving axle,.The main index of axle is DWT, and the front axle is 5 ton class and 6 ton class. After the bridge has 8 tons, 9 tons, 10 tons, the largest domestic 13 tons. How many bridges should be loaded depends on the overall weight of the car. If a 8 ton rear axle plus a 4 ton front axle, then the total quality of this car is 12 tons, that is, about 8 tons of load. If two 10 ton rear axle plus 6 ton front axle, then this car can carry about 20 tons or so
