摘要： The invention relates to a drive device for an all-wheel-drive two-track motor vehicle, in the powertrain of which a drive assembly (1) outputs permanently to a first vehicle axle (VA) and to a second vehicle axle (HA) via a center clutch (13) during a driving operation. When the center clutch (13) is engaged, the second vehicle axle (HA) is connected to the powertrain, and when the clutch (13) is disengaged, the second vehicle axle (HA) is decoupled from the powertrain. In a driving situation in which the all-wheel drive is enabled and has axle frictional coefficients (µVA, µHA) of differing values, a greater wheel torque (MVA) can be applied to the vehicle axle (VA) with the larger axle frictional coefficient (µVA) than to the vehicle axle (HA) with the smaller axle frictional coefficient (µHA). A controller (27) is provided which limits the drive assembly (1) to a maximally allowable motor torque (Mmot,max) in order to limit the motor torque. According to the invention, the controller (27) has an analysis unit (29) with which the maximally allowable motor torque (Mmot,max) can be ascertained and adapted in order to prevent an overload of the vehicle axle (VA) with the larger axle frictional coefficient (µVA). The maximally allowable motor torque (Mmot,max) is produced by adding (45) a structurally specified overload threshold (MVA,Ü), which is stored in the analysis unit (29) and which, once reached, indicates the risk of component damage to the vehicle axle (VA) with the larger axle frictional coefficient (µVA), to at least one maximally allowable potential moment of inertia component (MT,HA) on the vehicle axle (HA) with the smaller axle frictional coefficient (µHA), said moment of inertia component (MT,HA) relieving the load on the vehicle axle (VA) with the larger axle frictional coefficient (µVA).
