Disconnecting differential and electric drive transmission system having the same

A disconnecting differential, which comprises a differential housing and a planet carrier arranged in the differential housing, the disconnecting differential further comprising:

• a first one-way clutch and a second one-way clutch, wherein the first one-way clutch and the second one-way clutch are arranged in parallel between the planet carrier and the differential housing, outer rings of the first one-way clutch and the second one-way clutch are connected to or formed integrally with an inner wall of the differential housing, and inner rings of the first one-way clutch and the second one-way clutch are connected to or formed integrally with an outer wall of the planet carrier;
• and the first one-way clutch is configured to be locked in a forward rotation driving condition and a reverse rotation coasting condition, and to slip in a reverse rotation driving condition and a forward rotation coasting condition, and the second one-way clutch is configured to be locked in the reverse rotation driving condition and the forward rotation coasting condition, and to slip in the forward rotation driving condition and the reverse rotation coasting condition;
• and
• an interruption device, comprising a power section and an interruption section, wherein the interruption section is configured to rotate synchronously relative to the differential housing and to shift all rolling elements in the second one-way clutch under the action of the power section, such that the second one-way clutch slips in the forward rotation coasting condition so as to release a locking function of the second one-way clutch, and the interruption section is further configured to release the shifting of all of the rolling elements, so as to restore the locking function of the second one-way clutch.
