摘要： A power assistance drive for a steering column of a motor vehicle may include a belt drive arranged in a housing, with an input pulley that is coupled to the motor shaft of a motor so as to be rotationally drivable about an input axis and which is drivingly connected by means of a drive belt to an output pulley that is mounted in the housing so as to be rotatable about an output axis. To enable a repair-friendly design and easier replacement of the motor, the motor may be releasably attached to the housing and the motor shaft may be connected to the input pulley by means of a releasable coupling.

摘要： A coupling element for fitting to a threaded spindle. The coupling element has a receiving portion which is formed integrally with a coupling portion. The receiving portion extends in a hollow-cylindrical manner along an axis having an axial receiving opening for receiving the threaded spindle, and the coupling portion is flattened transversely with respect to the axis relative to the receiving portion and has a connection means. In order to be able to produce a coupling element in a more efficient and flexible manner, the receiving portion and the coupling portion be formed from a continuous integral pipe portion, wherein the coupling portion has a pressing portion in which the pipe portion is plastically compressed flat transversely relative to the axis.

摘要： A steering column for a motor vehicle may include an actuating unit in which a steering spindle is rotatably mounted and which is held in an adjustable manner by a supporting unit, an adjustment device for adjusting the actuating unit with respect to the supporting unit, and a position-sensing device that includes a first sensor unit for sensing the position of the actuating unit with respect to the supporting unit. The position-sensing device may also include a second sensor unit for sensing a state when the actuating unit is in a predetermined position relative to the supporting unit. One or both of the sensor units may be configured to operate in a contactless manner.

摘要： A method to control a steer-by-wire steering system of a road vehicle, the steer-by-wire steering system including a feedback actuator to apply a feedback torque to a steering wheel and a road wheel actuator to turn steerable road wheels with two redundant power packs each, the method including, if a failure in the road wheel actuator is detected, increasing the feedback torque provided by the feedback actuator to a value higher than a calculated feedback torque, and if a failure in one power pack of the feedback actuator is detected, increasing the feedback torque provided by a functioning power pack of the feedback actuator to a value higher than the calculated feedback torque.

摘要： A method of controlling a steering system for a vehicle includes determining a state of performance degradation of the steering system, determining a vehicle situation, determining if a performance of the steering system in the determined state of performance degradation is sufficient for the determined vehicle situation, and, if the performance of the steering system is not sufficient, modifying the state of performance degradation by decreasing a degradation level for a period of time.

摘要： An electromechanical motor vehicle steering system includes an electric motor and an electronic control unit. The electromechanical motor vehicle steering system is at least partially surrounded by housing parts. At least two of the housing parts are connected to one another by interference fit, wherein the interference fit is at least partly a tapered interference fit.

摘要： A steering column for a motor vehicle may include a crash device that has at least two components that have mutually facing surfaces. The at least two components may be connected to each other by means of a shear element that is arranged in an opening passing at least partially through the components such that the shear element is broken in two if the components move relative to each other. To improve the predetermined breaking connection, the opening may have, in at least one edge region bounding one of the mutually facing surfaces, a widened portion that extends at least over a partial circumferential region and is open towards the respective other surface.

摘要： A helical gear transmission for an electromechanical servo steering mechanism may include a shaft that meshes with a helical gear. The shaft may be arranged in a transmission housing and, at its first end, may be mounted in a drive-side bearing arrangement so as to be rotatable about an axis of rotation. At its second end, the shaft may be mounted in a drive-remote bearing arrangement in the transmission housing. The drive-side bearing arrangement may have a rolling bearing, an outer ring of which is spherical. The rolling bearing may be enclosed by two bearing shells. The outer side of the outer ring may have two flat points that are opposite one another and form a pivot axis about which the shaft is pivotable in a direction of the helical gear.

摘要： A steering column may include a casing unit in which a steering spindle is mounted rotatably about a longitudinal axis extending in a longitudinal direction, and casing tubes that are adjustable telescopically relative to one another in the longitudinal direction. A roller guide with at least one bearing support can be displaced radially on a first of the casing tubes, and in which at least one roller is mounted rotatably about a roller axis that is transverse to the longitudinal axis. The roller can roll via its outer circumference in the longitudinal direction on a second of the casing tubes. A pretensioning device interacts with the bearing support to pretension the roller against the second casing tube. The bearing support may be guided on the first casing tube with an oblique inclination relative to the longitudinal axis, and the pretensioning device may apply an axial force to the bearing support.
