  • Patent number: 11988270
    Abstract: The disclosure relates to the technical field of electric drive assemblies, and in particular provides an electric drive assembly for an electric vehicle, and an electric vehicle. The disclosure provides an electric drive assembly composed of an input shaft integrated with an electric motor rotor and a gearbox first-stage driving gear, three intermediate shafts each integrated with a gearbox first-stage driven gear and a second-stage driving gear, and a differential integrated with a second-stage driven gear. The three intermediate shafts are evenly disposed around the input shaft. The power of the electric motor is transmitted from the first-stage driving gear to the second-stage driven gear on the differential evenly through the three intermediate shafts.

  • Patent number: 11892064
    Abstract: An electric drive transmission system includes a disconnecting differential. The disconnecting differential comprises a first one-way clutch, a second one-way clutch and an interruption device. 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. 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, and wherein 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.
