Abstract: The disclosure relates to a method for operating a steering system of a vehicle having a front-axle steering assembly, a rear-axle steering assembly and a steering wheel. The method involves detecting a failure of the front-axle steering assembly, steering the vehicle exclusively via the rear-axle steering assembly based on a steering command issued by a driver via the steering wheel, comparing at least one detected physical value of the steering command with a limit value associated with the rear-axle steering assembly and, provided the at least one associated limit value is reached or exceeded by the at least one detected physical value of the steering command, applying a torque acting on the steering wheel via the electric motor coupled to the steering wheel, which torque counteracts the steering command.

Abstract: An aerodynamic body with an aerodynamic body surface that creates a contoured surface for a fluid to stream around, with a device to influence the flow of the fluid streaming around the aerodynamic surface. The flow-influencing device includes a passage to link the fluid streaming around the aerodynamic surface with an actuator space of an aspirating and purging device situated in the aerodynamic body, and an indentation that is situated next to the passage, which is formed by a recessed section of the aerodynamic surface on a flow-influencing region within the contoured surface of the aerodynamic surface, so that a boundary wall is configured as part of the recessed surface lying opposite the indentation. The aspirating and purging device can generate a swirl in the flow of the fluid streaming around the aerodynamic surface, the rotational axis of which is directed along the assumed aerodynamic body chord direction.

Abstract: A wet-type rotor pump which is particularly suitable for feeding coolant in motorcar engines comprises a pump wheel. By the pump wheel, a feed medium is fed through an intake channel into a discharge channel. Via a common shaft, a motor armature of an electric motor is connected with the pump wheel. The motor armature is surrounded by a slit pot, feed medium flowing around the motor armature to cool it. The shaft is supported by two radial bearings, one radial bearing being arranged in a supporting element. The supporting element that is arranged within the intake channel further comprises an abutting surface on which a flow surface of the pump wheel abuts to take up axial forces.

Abstract: The invention rests on the idea that the information for controlling an EC-motor is taken from the adjustment or position of the control unit, which can be ascertained by means of a position indicator, such as a potentiometer, Hall indicator, etc. The current pattern for the EC-motor can thereafter, for example, be determined in a microcomputer disposed in the motor control for the control unit, without the motor having a rotor position determination.

Abstract: The electric motor comprises an internal rotor and an external stator with stator windings. The rotor comprises several permanently magnetic pole shoes. The stator windings are supported by stator pole shanks comprising, radially inside, stator pole shoes facing the rotor pole shoes. Via a short circuit bridge, the stator pole shoes are connected with the adjacent stator pole shoes so that all the stator pole shanks are integrally formed with each other. Radially outside, the stator pole shanks and stator pole shoes are connected with each other only by a separate yoke ring set thereon. All the windings are wound from radially outside with one single continuous winding wire when the yoke ring has been removed.
