The present disclosure relates to a bearing arrangement for supporting a shaft, in particular a shaft of a gearing mechanism for an electromechanical brake booster, having: at least one bearing, a shaft, which is at least section-wise accommodated in the at least one bearing and has a protruding, rounded region on at least one of its axial end surfaces, at least one spring element, that engages the protruding, rounded region in order to prestress the shaft in the axial direction.

Bearing arrangement

An arrangement of a transmission () and an attachment module (), in which the transmission () has a driveshaft () with a central, first axial bore () for supplying lubricating oil and the attachment module () has a connecting shaft () mounted in the housing by at least one roller bearing (). The driveshaft () and the connecting shaft () are connected to one another, in a rotationally fixed manner, by a splined connection (). The supply of lubricating oil for the spline connection () and the at least one roller bearing () occurs by way of the central, first axial bore () of the driveshaft ().

Arrangement of a transmission and of an attachment module

A device for a vehicle drive train for generating and transmitting drive torque to components of the drive train. The device comprises a shaft which is connected to the components of the drive train, at least first and second bearings which support the shaft and an electric motor for generating the transmitted drive torque. The electric motor comprises a stator and a rotor which is fixed to the shaft. The rotor is supported by one or more bearing surfaces. The device also comprises elements disposed on the shaft via which drive torque can be transmitted to the components of the drive train while introducing transverse force into the shaft. The rotor of the drive motor is positioned on the shaft such that the bearing surface is located in the region of maximum deflection caused by the transverse force in the shaft.
