The function of the transfer case
The function of the transfer case is to distribute the power output from the transmission to each of the transaxles and further increase the torque. The transfer case is also a gear transmission system, which is separately fixed on the frame, and its input shaft is connected with the output shaft of the transmission by a universal joint device, and the output shaft of the transfer case has several roots, respectively, through a universal joint device and each The drive axle is connected.
Most transfer cases have a larger load than the gearbox due to the effect of speed reduction and torque reduction. Therefore, the common gears in the transfer case are helical gears, and the bearings are also supported by tapered roller bearings.
