Abstract
The utility model discloses a double speed transfer case which is composed of a gearbox, a shell body, a rear driving device and a front driving device. The rear driving device is installed at the upper end of the shell body, and then sealed through a top cover. The front driving device is installed at the bottom end of the shell body. The gearbox is connected with the rear driving device through a second gearbox shaft. The gearbox and the shell body are tightly locked together through a plurality of bolts. Due to the fact that the gearbox and the shell body are tightly locked together through the plurality of bolts, the double speed transfer case is directly connected with an output shaft of the rear driving device through the second gearbox shaft, so that a transmission shaft and flange accessories used for connecting the gearbox and the driving devices are eliminated. The whole transfer case is compact, resonance generated in the process of working of the gearbox case is reduced, stable running of a vehicle in land is guaranteed, manufacturing cost is reduced, and installation and maintenance are convenient.
