DIFFERENTIAL SYSTEM

A differential system is disclosed, which comprises a differential and a differential disconnect mechanism. The differential comprises an outer differential housing (1) and an inner differential housing (2), and the outer differential housing (1) is used for transmission connection with an upper stage transmission structure of the differential. The differential disconnect mechanism comprises a disconnect clutch (40), first end face teeth (7) and second end face teeth (8). The first end face teeth (7) are disposed between the outer differential housing (1) and the inner differential housing (2) and are movably connected with the outer differential housing (1) so that the first end face teeth (7) can move axially and rotates synchronously relative to the outer differential housing (1). The second end face teeth (8) are fixedly connected with the inner differential housing (2). The disconnect clutch (40) is connected with the first end face teeth (7), and is configured to drive the first end face teeth (7) to move axially relative to the second end face teeth (8), and control the first end face teeth (7) and the second end face teeth (8) to engage or disengage. The differential system can quickly disengage or engage the power of the differential, and has the advantages of high torque transmission efficiency, long service life, compact structure, and being convenient to be arranged in the vehicle and so on.
