摘要： A clamping apparatus may include a stroke-generating disk that is rotatable about a clamping axis and is connected via a first stroke-generating gearing and a second stroke-generating gearing to a pressure disk, which is stationary relative to the rotation of the stroke-generating disk. The first stroke-generating gearing converts a relative rotation of the stroke-generating disk in a first actuating angle range in the clamping direction into a first axial stroke relative to the pressure disk. The second stroke-generating gearing converts a further rotation of the stroke-generating disk following the first actuating angle range in a second actuating angle range into a second axial stroke between the stroke-generating disk and the pressure disk. At least one of the stroke-generating gearings is a tilting pin gearing, with at least one tilting pin supported in the direction of its pin axis between corresponding bearing points on the stroke-generating disk and the pressure disk.

摘要： A steering column for a motor vehicle may include a casing unit in which a steering spindle is mounted such that the steering spindle is rotatable about a longitudinal axis that extends in a longitudinal direction. The casing unit has at least two telescopically guided casing tubes that are adjustable relative to one another in the longitudinal direction, an intermediate element that is movable in the longitudinal direction and is arranged between the casing tubes, and a positioning device for positioning the intermediate element in the longitudinal direction relative to the casing tubes. The positioning device may have elongate guide tracks that are arranged on the casing tubes and the intermediate element and interact with one another such that they position the casing tubes and the intermediate element relative to one another in a defined manner.

摘要： A process can produce alcohols having at least two carbon atoms by catalytic conversion of synthesis gas into a mixture containing alkanes, alkenes, and alcohols. Alkenes are converted into corresponding alcohols in a subsequent step by hydration of the alkanes. Before the hydration and after the catalytic conversion, gas and liquid phases may be separated. Specific catalysts can be employed that have a markedly higher selectivity for alkenes than for alkanes. These catalysts comprise grains of non-graphitic carbon having cobalt nanoparticles dispersed therein. The cobalt nanoparticles have an average diameter dp from 1 to 20 nm, and an average distance D between nanoparticles is from 2 to 150 nm. The combined total mass fraction of metal ω in the grains ranges from 30% to 70% by weight of the total mass of the grains of non-graphitic carbon, wherein 4.5 dp/ω>D≥0.25 dp/ω.

摘要： Methods for providing steering assistance for an electromechanical steering system having a redundant control unit with a primary and a secondary control path. Respective primary and secondary control paths each have a computing unit, gate driver module, and power module. The method includes detecting an applied steering torque; calculating a primary and secondary motor target torque in the primary computing unit as a function of the applied steering torque; transmitting the primary motor target torque to a primary motor controller of the primary computing unit; determining primary motor currents to operate a primary electric motor or a primary winding group of the electric motor in the primary motor controller; transferring the secondary motor target torque from the primary computing unit to a secondary motor controller and determining secondary motor currents for operation of a secondary electric motor or a secondary winding group of the electric motor.

摘要： A method for operating a motor vehicle steering system may involve generating a steering feel, with a steering force assistance or a countertorque that is introduced by a feedback actuator into a steering handle, in a manner that is dependent on a driver-side manual torque applied to the steering handle. The steering feel may be represented by way of a characteristic curve that is adapted in a manner that is dependent on steering speed in the case of steering speeds above 100°/s such that an adapted characteristic curve has a smaller maximum change of the gradient than the characteristic curve in the case of lower steering speeds.

摘要： A method for training a machine-learning module of a computer-implemented prediction model for predicting product quality parameter values for one or more quality parameters of a chemical product produced by a chemical production plant. The production plant includes a plurality of sensors, each of which is configured to acquire process parameter values for one or more process parameters of a chemical process carried out by the production plant for producing the chemical product during operation of the production plant. A priori information about the production plant and the process carried out by the production plant is used, including chronological sequence information about a chronological sequence of the process carried out within the production plant, for which sensors sensor-specific time shifts between an acquisition time of training process parameter values and a production time of a product unit, during the production of which the corresponding training process parameter value was acquired.

摘要： A multiphase electric motor is disconnectable from a DC voltage source by way of a control unit. Phase windings with connection lines can each be alternately connected via a high-side and a low-side switching element to a respective pole of the DC voltage source, and the connection lines each have a device for disconnecting the phase windings from the DC voltage source upon a fault. The control unit may monitor the switching elements for short-circuit faults, switch off the switching elements when a fault occurs, determine whether the switching element causing the fault is a high-side or a low-side switching element, switch on at least a second of the high-side or correspondingly at least a second of the low-side switching elements in addition to the switching element causing the fault to brake the electric motor, switch off the switching elements after a braking period, and open the phase disconnection devices.
