Abstract: The invention relates to a preferably bistable magnetic brake, which is intended in particular for locking an actuating device of an electromechanical wheel braking device in its braking position at a given time. To enable releasing the magnetic brake even in the event of a defect, the invention proposes embodying the magnetic brake with two redundant electromagnets for its actuation.

Abstract: A method and a device for controlling wheel brakes is proposed. To improve the availability and to fulfill legal requirements imposed on an electrical braking system, a control of the valves derived from a second power circuit independent of the first one is provided in the event of a fault, via which the braking pressure in the at least one wheel brake can be set even in the event of a fault.

Abstract: A brake pedal path simulator, with a restoring device which exerts a restoring force with a progressive force-path characteristic curve on a pedal. The restoring device includes at least two permanent magnets, whose mutually repelling poles are oriented toward each other, one of which magnets is connected to the pedal and is guided in a direction of the resultant repelling magnetic force of the other magnet.

Abstract: An electromagnetically operated proportional valve, in particular a pressure regulating valve for automatic transmission of motor vehicles has a magnet housing, a magnet coil and stationary flux guiding elements received in the magnet housing, a magnet armature, a valve member with which the magnet armature cooperates, stationary structural elements forming at least one auxiliary air gap and a working air gap in a magnetic circuit, the valve member cooperating with the stationary structural elements through the at least one auxiliary air gap and the at least one working air gap, at least one of the structural elements cooperating in the working air gap being at least partially provided on at least one surface facing a corresponding another structural element with at least one nonmagnetic coating.
