The invention relates to a vehicle wheel system (1) for motor vehicles comprising a central wheel disc (2) having an attachment flange (27) for arrangement on a chassis component (14), and having a brake rotor (4) which is provided coaxially with respect to a central rotational axis Ax and whose external circumference is secured to the wheel disc (2) but is otherwise freely oriented in the radially inward direction. The object is to propose a vehicle wheel system which is of lightweight construction and easy to maintain. The object is achieved according to the invention in that the brake rotor (4) is secured in an exchangeable fashion by a plurality of support sections (16) at its outer circumference with detachable attachment means (6) and, for the purpose of conducting away heat, is secured in a thermally conductive fashion to a plurality of abutment sections (17) on the circumference of the wheel disc (2), with the result that overall a modular design (MAB) is obtained.

The aim of the invention is to integrate a steering device for adjusting a steer angle of a motor vehicle wheel, particularly a rear wheel, into a conventional wheel suspension. Said aim is achieved by a steering device comprising at least one wheel guiding member via which a wheel support is connected to a vehicle body. The wheel support is pivotable about an axis of rotation that extends substantially parallel to the wheel plane while the wheel guiding member is hingedly connected to wheel support at a distance from the axis of rotation. The length of the wheel guiding member is adjustable by means of a drive unit.

The invention relates to a device for determining the steering wheel angle, comprising an angle sensor (10) which measures, in a precise manner, the corresponding angle range in at least one full rotation of the steering wheel (9) with a first accuracy; an incremental measuring angle sensor (11) which emits a first output signal which enables a modification of the angle position of the steering wheel (9) to be determined with a second accuracy which is greater than the first accuracy, and which emits a second output signal when the steering wheel (9) takes up at least one predetermined position which is assigned to at least two reference steering wheel angles, and an evaluation unit (12) which is connected to the angle sensors (10, 11). The evaluation unit (12) determines the steering wheel angle from an output value determined by means of a precisely measuring angle sensor (10), in accordance with the first output signal of the incremental measuring steering wheel angle (11). The evaluation device (12) adapts the value of the steering wheel angle to one of the reference steering wheel angles when the second output signal appears. The invention also relates to a method for determining the steering wheel angle.

The invention relates to a differential drive (6) for a superimposed steering system, wherein the steering angle inputted by the driver can be superimposed with another angle by means of a control in accordance with correcting variables and the multiplication can be changed. The invention is characterized in that electromechanical locking (1, 2, 313) of the differential drive (6) takes place depending on other correcting variables reproducing the operating state of the vehicle.

The invention relates to an actuating unit for an electromechanically actuatable disk brake for motor vehicles. Said actuating unit essentially comprises a drive unit (1) or an electric motor (11), an actuating element (7) by which means one (4) of two friction linings (4,5) which are displaceably arranged in a caliper is brought into contact with a brake disk (6), and a reduction gear (2). In order to be able to decouple the reduction gear (2) from the rotor (10) of the electric motor (11), the rotor (10) is rotatably mounted at both ends and a torsion-proof and radially non-rigid connection (13) is provided between the rotor (10) and the reduction gear (2).

The invention relates to a threaded mechanism with rolling bodies that comprises a spindle rod (1), a spindle nut (4) at least partially enclosing said spindle rod, and a number of interposed rolling bodies (3). The inventive mechanism is especially characterized in that the spindle nut (4) is provided with an axial and a radial bearing that is adapted to receive both tilting motions of the spindle nut (4) about its longitudinal axis as well as radial motions at an angle to its longitudinal axis.

The invention relates to a locking device (1) for an electromechanically actuated wheel brake of a motor vehicle by means of which such a wheel brake can be blocked in an applied state. To this end the locking device (1) comprises an electrically controlled switching unit (2) and a pawl (3) which cooperates with at least one element (4) serving to transmit the actuating force of the wheel brake. The pawl (3) is also coupled to the switching device (2) so that the wheel brake can be blocked in its prevailing state of actuation. The above type of locking device (1) requires only little space at installation and offers an easy way of providing a reliable parking brake function.

The invention relates to an electronically adjustable brake actuation system for motor vehicles, comprising a master cylinder (2) with a pressureless hydraulic fluid tank (3), a pressure source (20) which can be controlled by an electronic control unit (32) enabling pressure to be exerted upon the wheel brakes (7, 8, 9, 10) of the motor vehicle. Said brakes can be joined to the master cylinder (2) by at least one hydraulic connection (11, 14) which can be shut off by a block valve (12, 15). The invention is also provided with a device (13, 33) for detecting the driver's desire to decelerate, in addition to at least one separating piston (16) arranged upstream from the wheel brakes (7-10) and whose first chamber (17) can be connected to the master cylinder (2) and whose second chamber 919) can be connected to the pressure source (20) or the hydraulic fluid tank (3) by a valve device (27, 271). In order to improve the dosing of braking pressure in said system, the invention provides that the valve device (27, 271) is formed by a multiposition valve built like a gate valve, and that a switching seat valve (29) is inserted in the joint between the multiposition valve (27, 271) and the pressure source (20).
