  • Patent number: 11850928
    Abstract: An electric drive axle for a vehicle includes at least one first electric vehicle drive system (1) for driving at least one vehicle wheel (11, 12) and at least one connection interface (8) for at least one power take-off (PTO). The vehicle drive system (1, 13) is coupled at least to one first double shift element (6) such that, at least in a first engagement position of the first double shift element (6), the vehicle drive system (1, 13) is drivingly coupled to at least one vehicle wheel (11, 12) and, in a second engagement position of the first double shift element (6), the vehicle drive system (1, 13) is decoupled from the at least one vehicle wheel (11, 12) and is drivingly coupled to the connection interface (8) for the power take-off (PTO). A vehicle with an electric drive axle is also provided.

  • Patent number: 11807091
    Abstract: An axle drive (1) for a motor vehicle axle includes at least a first drive unit (2), a second drive unit (2), and an output axle (6). The first and second drive units (2) are arranged such that an overall center of gravity (7) of the axle drive (1) is situated proximate to a center of the output axle (6) and/or an axis of rotation of a vehicle wheel of the motor vehicle driven by the axle drive (1).

  • Patent number: 11780328
    Abstract: A drive device for an electrically driven axle of a motor vehicle may include at least one electric machine, a shiftable transmission connected downstream from the at least one electric machine, and a differential coupled to the transmission for distributing drive torque to the axle. The transmission has first and second planetary gear sets connected in series. The at least one electric machine engages with an external toothing of a ring gear of the first planetary gear set. A carrier of the first planetary gear set is rotationally fixed to a sun gear of the second planetary gear set. A sun gear of the first planetary gear set is detachably couplable to a housing. A ring gear of the second planetary gear set is coupled to the housing. A carrier of the second planetary gear set is an output of the transmission. The first planetary gear set is interlockable.
