Abstract: A brake-pressure control device for a motor-vehicle braking system, with an electric motor, the rotatory motion of which is transformed by a ball screw drive into a translatory motion of a piston in a working cylinder, in order to be able to build up a defined braking pressure in a wheel brake independently of actuation of a master brake cylinder. An aspect provides that the ball screw drive is provided with a friction slip coupling engaged over a profiled tube which is fixedly connected to a nut of the ball screw drive and to which the piston is fixed.

Abstract: In a method for producing a rotor, permanent magnets are arranged about a lateral surface in a recess of a rotor body from a selected position, e.g. a central position of the longitudinal extension of the rotor body, toward one side or toward two sides along an axis of rotation of the rotor body in side-by-side disposition. An end plate band covers a variable gap formed as a result of manufacturing tolerances of the permanent magnets between an outer face of an outermost one of the permanent magnets and an inner surface of the recess in an area of the recess which is non-parallel to the lateral surface. Subsequently, the permanent magnets and the end plate band are covered with a sleeve.

Abstract: Helical spring is mounted between two lever arms which are hinged together at one end; the spring is attached at its ends to disks which are pivoted rotatably to the lever arms, the spring axis being parallel but eccentric to the line joining the two pivot points. Rotation of the disks moves the spring closer to or farther from the hinge point, effectively changing the elastic constant between the distal ends of the lever arms, which are points of attachment to a vehicle chassis and to its running gear, respectively. Spring position may be adjusted by worm drive operated manually by crank or by motor controllable by driver from instrument panel; this adjusts vehicle springing to various vehicle loads.
