How many tractors does it take to pull 150 tons?
It takes 390---420 horsepower to pull 150 tons. It's not horsepower, it's the speed ratio of the car, the wheel bridge.
Through the bridge is a double rear axle drive truck bridge (by the front of the root), the drive shaft from the front into the bridge, in addition to drive reducer, also drives a shaft through the bridge shell, stretched out from behind the driver behind the root bridge, so the bridge is a through bridge.
The transmission gearbox is the input and output speed ratio, that is to say: the transmission ratio of gearbox input speed than the output speed, such as the input speed is 3000r/min, the output speed is 1000r/min, the variable speed ratio is: 3000/1000=3.
This bridge is called wheel side reduction axle, referred to as wheel bridge. The utility model has the advantages of better speed reduction performance (increased driving force), improved vehicle performance, and improved cost. The high-speed rotation of the drive shaft torque, into a larger driving force in the drive axle, a reduction gear, the drive axle of the conventional gear in the middle of the pack (commonly known as dental package) has a set of cone gear group (commonly known as basin angle gear), to slow down. As the basin tooth is larger, the gear housing in the middle of the axle must be enlarged, too. It is a kind of design of reducer in the hub, which is at the end of half shaft gear is a small diameter, a planetary gear set around (usually 5), hub toothed surround the planetary gear, in order to achieve the purpose of driving gear.
