Abstract: A method is provided for protecting an all-wheel drive clutch of a two-axle vehicle with clutch-controlled all-wheel drive. A power braking situation, where both the accelerator pedal and the brake are actuated and the vehicle is stationary or moves only slightly in the vehicle longitudinal direction, may be critical for the all-wheel drive clutch. For example, when the friction coefficient of the primary axle is very small and the wheel braking torque is less than the driving torque, a clutch slip may occur at the all-wheel drive clutch. Upon detecting a power braking situation, a protective measure is implemented against thermal overload of the all-wheel drive clutch, such as reducing or limiting the engine torque output, so that the clutch slip and the energy input into the all-wheel drive clutch are reduced.

Abstract: In a flow deflector structure for an intake air duct of an internal combustion engine which includes a housing with air inlet and outlet openings arranged at a predetermined angle with respect to each other for redirecting air flowing through the deflector structure and with flow guide vanes curved according to the flow direction change provided by the flow deflector structure, the housing has a flow cross-section which is larger than the flow cross-section of the inlet and outlet openings and a side wall opening with a cover to facilitate forming, or insertion of the guide vanes in the housing.
