The disclosure relates to the field of electric drive transmission systems for vehicles, and in particular provides a disconnecting differential and an electric drive transmission system having the disconnecting differential. The disconnecting differential comprises a first one-way clutch, a second one-way clutch and an interruption device, wherein the first one-way clutch and the second one-way clutch have opposite locking directions and are coaxially sleeved between a planet carrier and a differential housing; and the interruption device comprises a power section and an interruption section, wherein the power section is located on an inner wall of a reduction gearbox, the interruption section is located on the differential housing and can shift, under the action of the power section, all rolling elements of the one-way clutch locked in a forward rotation coasting condition, thereby realizing selective releasing of the locking function of the one-way clutch. In this way, power transmission in a reverse power transmission state such as coasting of a vehicle is selectively interrupted while achieving the speed differential and forward and reverse power transmission functions of a normal differential. The structure is novel and the operation accuracy is high, and the NVH problem during engagement can also be avoided.
A disconnecting differential, which comprises a differential housing and a planet carrier arranged in the differential housing, the disconnecting differential further comprising:
