Multiple individual adjoining plates pushed onto a shaft or of partial laminated cores having multiple plates have a central borehole accommodating the shaft. At least a part of the plates or partial laminated cores are pushed onto the shaft pivoted by a predetermined pivot angle (?). Every plate or partial laminated core includes multiple coolant passages arranged distributed around the center (Z) of the borehole. The angle offset of two adjacent coolant passages corresponds to the pivot angle (?).

Abstract: The present disclosure relates to a method for detecting a malfunction of at least one environment sensor of a motor vehicle operating while the motor vehicle passes a predefined gate region of a road network. Detection data is determined based at least in part on sensor data from the at least one environment sensor. A deviation of the detection data from reference data is determined. The reference data describes at least one object actually present in the gate region. An entry regarding a malfunction of the at least one environment sensor is stored when the deviation fulfills a predefined indicator criterion.

Abstract: A predefined virtual theme defines a specific virtual way of movement within a virtual environment. A route is selected which best matches the predefined virtual theme Movements of the motor vehicle are detected during a journey along the selected route. The virtual reality glasses are controlled so that a vehicle occupant wearing the virtual reality glasses moves virtually within the virtual environment according to the detected movements of the motor vehicle and according to the predefined virtual way of movement of the predefined virtual theme.

Abstract: The disclosure relates to a drive device for a vehicle axle, especially a rear axle, of a two-track vehicle, wherein the vehicle axle includes an axle differential, which can be connected at the input end to a primary drive machine and at the output end to flange shafts arranged on either side with vehicle wheels of the vehicle axle, wherein the vehicle axle is associated with a shiftable superimposing gear, which can be shifted to a torque distribution mode by a torque distribution shift element, in which a drive torque generated by an additional drive machine in a first load path can be coupled to one of the flange shafts in order to change a torque distribution on the two vehicle wheels, and the drive torque generated by the additional drive machine can be coupled to the input side of the axle differential in a second load path.

Abstract: A method for operating a hydraulic valve of a hydraulic device of a motor vehicle transmission device, wherein an actuating current of the hydraulic valve is superposed with a modulation alternating current in order to adjust a shaking vibration of the hydraulic valve by a control device, wherein a deviation between an actual pressure resulting from the actuating current and a setpoint pressure determined as a function of the actuating current is determined for the hydraulic device by means of an electronic computing device, and an amplitude and/or a frequency of the modulation alternating current is increased as compared to a starting value equalizing a hysteresis of the actual pressure relative to the setpoint pressure, as a function of a tolerance range being exceeded by the determined deviation.
