[0002] The part-time four-wheel drive transfer case with differential is a four-wheel drive system that can only use the dual-drive system (two-wheel drive) during normal driving according to needs. When stronger traction is needed, the four-wheel drive conversion can be performed by manually operating the transfer case. In addition, the differential lock function can help better solve driving problems under high friction conditions.

In this embodiment, an extension is provided at the output end of the differential housing, and an internal spline is provided in the extension that is connected to the transfer case. After the power is transmitted to the differential through the gearbox, one path is transmitted to the front wheels, and the other path is transmitted to the rear wheels through the transfer case, thereby realizing the four-wheel drive function, stable power transmission, good maneuverability, strong adhesion, simple structure and practicality.
