What is a car transfer case[汽车基本知识]

Off-road vehicles need to often drive on bad roads and no roads, especially militarycarThe driving conditions are more severe, which requires an increase in the number of driving wheels of the car. Therefore, off-road vehicles are driven by multiple axles. For example, if both front wheels of a front-wheel drive car are stuck in a ditch (this is often encountered on bad roads), then the car will not be able to use the power of the engine to generate driving force through friction between the wheels and the ground to move on. . And if the four wheels of this car can generate driving force, then the two wheels that are not stuck in the ditch can work normally, allowing the car to continue driving. SplitterThe function oftransmissionThe output power is distributed to eachDrive axle, And further increase the torque.The transfer case is also a gearTransmission system, It is separately fixed on the frame, its input shaft is connected with the output shaft of the transmission with a universal transmission device, and the output shaft of the transfer case has several, which are respectively connected with each drive axle through the universal transmission device. Most transfer cases have a heavier load than the gearbox due to the effect of reducing speed and increasing torque. Therefore, the constant mesh gears in the transfer case are all helical gears, and the bearings are also supported by tapered roller bearings.
