Abstract:
A drive device for an all-wheel drive, two-track motor vehicle, in the drive train of which a first motor vehicle axle and, via a center clutch, a second motor vehicle axle are driven permanently by a drive assembly in driving operation. In the closed state of the center clutch, the second vehicle axle is engaged with the drive train, and, in the open state of the clutch, the second vehicle axle is decoupled from the drive train. In a driving situation with engaged all-wheel drive as well as with axle friction coefficients of varying size, a greater wheel torque can be taken up at the vehicle axle with a large axle friction coefficient than at the vehicle axle with a small axle friction coefficient, and a control instrument is provided, which, for engine torque limitation, limits the drive assembly to a maximum allowed engine torque.

Claim (Index 12):
A drive device for an all-wheel drive, two-track motor vehicle comprising:\n a drive train of which a first motor vehicle axle and, via a center clutch, a second motor vehicle axle are driven permanently by a drive assembly in a driving operation, wherein, in the closed state of the center clutch, the second motor vehicle axle is engaged with the drive train and, in the open state of the clutch, the second vehicle axle is decoupled from the drive train, wherein, in a driving situation with engaged all-wheel drive as well as with axle friction coefficients of varying size, a greater wheel torque can be taken up at the vehicle axle with a large axle friction coefficient than at the vehicle axle with a small axle friction coefficient, and wherein a control instrument is provided, which, for engine torque limitation, limits the drive assembly to a maximum allowed engine torque, wherein, for prevention of an axle overload at the vehicle axle with a large axle friction coefficient, the control instrument has an analysis unit, with which the maximum allowed engine torque can be determined and adjusted, and the maximum allowed engine torque can be determined from an addition of an overload threshold value that is predetermined and deposited in the analysis unit, for which, when it is attained, there is a danger of component damage at the vehicle axle with the large axle friction coefficient, and at least one maximum allowed, potential moment of inertia fraction at the vehicle axle with the small axle friction coefficient, said moment of inertia fraction relieving the vehicle axle with the large axle friction coefficient.
