摘要： A device for operating a steering system having at least one electrically operable actuator includes at least one carrier substrate on which a first electronics system and a second electronics system, which is at least partially redundant thereto, is arranged for operating the actuator. The at least one carrier substrate is sealed in a fluid-tight manner, at least in regions, by a protective coating. The first electronics system is sealed at least substantially by the protective coating, and the second electronics system is at least partially free of the protective coating.

摘要： A steering gear includes a gear wheel, a screw pinion meshing therewith, and a screw pinion shaft that includes the screw pinion. The screw pinion shaft is mounted on one side of the screw pinion in a fixed bearing. The steering gear includes a rotary bearing which comprises an inner bearing shell and an outer bearing shell. The outer bearing shell is connected to an inner ring of a swivel ring. The inner ring is connected to an outer ring of the swivel ring by a torsion web so as to pivot about a pivot axis. The torsion web runs at a distance from a supporting surface. The distance is dimensioned such that the torsion web does not contact the supporting surface when the screw pinion shaft is not loaded with a torque, and partially contacts the same when the screw pinion shaft is loaded with an operating torque.

摘要： An electromechanical actuator for rack-and-pinion steering includes a stator, rotor, and electronic system. The electronic system includes at least one first electronic sub-system and a second electronic subsystem, each operatively connected to the stator and the rotor. The at least one first electronic sub-system is arranged at least on a first circuit carrier plane and a second circuit carrier plane, and includes a first power output stage, a first control unit, and a first rotor position sensor arrangement. The second electronic sub-system is arranged at least on the first circuit carrier plane and a third circuit carrier plane, and includes a second power output stage, a second control unit, and a second rotor position sensor arrangement. The first, second and third circuit carrier planes are arranged perpendicular to an axis of rotation of the rotor, and are spaced apart from each other along the axis of rotation.

摘要： A method for monitoring the condition of an electronic power steering apparatus or of at least one part of the electronic power steering apparatus of a motor vehicle includes continually capturing acceleration measured values in a region of the electronic power steering apparatus during a driving mode of the motor vehicle and continually providing the captured acceleration measured values to a damage computation section in the form of a damage meter that continuously sums the acceleration measured values and continually forms therefrom at least one variable characterizing a degree of damage to the electronic power steering apparatus or to the at least one part of the electronic power steering apparatus. The method further includes continually comparing the variable with at least one prescribed limit value.

摘要： A method is described for operating a steering system (2) of a motor vehicle. A steering means (8) is connected to a steering gear (14) by means of an active steering system (4). During autonomous operation of the motor vehicle, a driver's intervention (40) in the steering means (8) is determined. The active steering system (4) is operated in such a way that a coupling (30) between an angle (26) of the steering means and an angle (28) input into the steering gear (14) is adjusted depending on the thus determined driver's intervention (40).

摘要： A steering system for a motor vehicle includes a steering column and a device for adjusting the steering column. The device includes a bearing block, a first guide mechanism, and a second guide mechanism. A housing of the steering column is adjustably mounted in the bearing block. The first guide mechanism is configured to adjust a height of the steering column in the bearing block. The second guide mechanism is configured to adjust an inclination of the housing, and includes at least one first guide plate and at least one second guide plate that are each movably connected to the housing of the steering column and to the bearing block so as to be axially movable with an adjustment of the inclination of the housing.

摘要： A belt drive has a drive gear, an output gear, a tensioning gear, and at least two belts. Each belt partly loops the drive gear and the output gear, and a strand of each belt partly loops the tensioning gear. A strand of a first belt loops the tensioning gear in one circumferential direction. This strand extends from the drive gear to the output gear. A strand of a second belt loops the tensioning gear in the other circumferential direction. This strand extends from the drive gear to the output gear. This belt drive achieves a large looping angle for the drive gear and the output gear, and correspondingly, a large transmission power. Additionally, the effect of the other belt enables a belt self-tensioning function which is independent of the rotational direction. Guiding the belts in this manner enables omission of an additional mounting of the tensioning gear.

摘要： The invention proposes a vane pump (VP) with adjustable delivery volume, which vane pump has a pump housing (G), a cam ring (KR) arranged therein, and a rotor (R) which is rotatably movably mounted therein. The vane pump (VP) has a regulating device (RV) through which the delivered pressure medium (DM) flows and which has two outlets (A1, A2) which are each connected to one of two pressure chambers (DK1, DK2) in order to charge these with regulable proportions of the pressure medium (DM), wherein, to change the eccentricity of the cam ring (KR) relative to the rotor (R), the two pressure chambers (DK1, DK2) act on the outer surface of the cam ring (KR). The vane pump (VP) has two criss-crossing control ducts (STK*, STK#) which connect in each case one of the outlets (A1, A2) to one of the two pressure chambers (DK1, DK2) in order to charge these with the regulable proportions of the pressure medium (DM). The criss-crossing control ducts (STK*, STK#) are preferably arranged in a cover (D′) of the pump housing such that the control ducts (STK*, STK#) are in a criss-crossing arrangement without coming into contact with one another. By means of this design, the vane pump (VP) can be easily reconfigured for a change in rotational direction of the rotor.
