The present invention relates to a shaft assembly (1) having an input shaft (2), an output shaft (3), a freewheel (5) and a transmission component (4). A connection (6) is formed between one of the shafts (2) and the transmission component (4). The freewheel (5) is arranged between the transmission component (4) and the other of the shafts (3). The shaft assembly (1) is designed to increase the torque-transmitting capability of the connection (6) between the shaft (2) and the transmission component (4) when a torque is applied to the freewheel (5) in a transmission direction (T). A torque can thus be reliably transmitted from the input shaft (2) via the transmission component (4) to the output shaft (3) in the transmission direction (T). The present invention also relates to a drive device having such a shaft assembly (1).

The invention relates to a parking lock assembly(15) with a drive device (16), a first drive element (24) that can be pivoted by the drive device (16) about a stationary rotational axis (29), and a second drive element (27) that is in operative connection with the first drive element (24) via a spring unit (28) and can be connected to the first drive element (24) for conjoint rotation via a latching device (30) and can be pivoted together with the first drive element (24) about the rotational axis (29) of the first drive element (24). An actuation element (31) can be brought into engagement or out of engagement with a locking element (18) on the basis of a pivoting movement of the second drive element (27), a rotational movement of a shaft (7) being lockable and releasable via said locking element. The second drive element (27) and the locking element (18) are paired with a spring device (34) that has a spring plate (34A) with a spring lug (34B) and at least one other spring lug (34D). The spring constant of the additional spring lug (34D) is lower than the spring constant of the spring lug (32B). The spring lug (34B) rests against the second drive element (27) under pre-tension in the release position of the locking element (18) and holds the locking element (18) in the release position. The other spring lug (34B) keeps the locking element (18) in contact with the actuation element (31) in the locked position.
A method is disclosed for operating a drivetrain of a working machine with a continuously variable transmission. The method comprises a step of detecting a current drive output rotation speed (10). The drivetrain is controlled (14) in such manner as to simulate a drivetrain with a fixed-gear transmission and a bridged converter transmission when the drive output rotation speed detected is higher than or equal to a drive output rotation speed limit. The drivetrain is controlled (16) in such manner as to simulate a drivetrain with a fixed-gear transmission and a coupled converter transmission when the drive output rotation speed detected is lower than the drive output rotation speed limit. In addition, the invention relates to a control unit for a drivetrain of a working machine with a continuously variable transmission, and a drivetrain for a working machine.

A device for grounding a rotor carrier is arranged inside of a grounded housing and includes a rotatable rotor carrier extending in an axial direction, a grounding device, and at least one bearing. The rotor carrier is supported by the at least one bearing. The grounding device is arranged on a housing arm next to the bearing and includes an electrically conductive annular carrier element with a central cut out. The carrier element forms a permanent electrically conductive connection to the housing arm at an inside surface of the carrier element. An electrically conductive sliding contact extends radially outward and forms an electrically conductive connection to the rotor carrier at an outer lateral surface of the sliding contact. By way of the sliding contact and the carrier element, an electrical connection is established between the rotor carrier and the housing.

DEVICE AND METHOD FOR OPERATING AN ELECTRIC AUXILIARY DRIVE FOR AN ELECTRIC VEHICLE, ELECTRIC VEHICLE, ELECTRIC AUXILIARY DRIVE FOR AN ELECTRIC VEHICLE, AND METHOD FOR PROVIDING REFERENCE DATASETS FOR A DEVICE FOR OPERATING AN ELECTRIC AUXILIARY DRIVE FOR AN ELECTRIC VEHICLE
A device for operating an electric auxiliary drive for an electric vehicle has a bidirectional inverter having a battery interface for electrically connecting to a vehicle battery and an auxiliary drive interface for electrically connecting to the auxiliary drive; a control arrangement having a first communications interface for connecting to the electric vehicle and a second communications interface for connecting to the auxiliary drive. The control arrangement inputs a configuration signal representing a present configuration of the electric vehicle and/or of the auxiliary drive via one of the communications interfaces. The control arrangement is formed to use the configuration signal to determine control parameters from a plurality of reference datasets with control parameters for different electric vehicles and different auxiliary drives, which control parameters are associated with respective configurations, and to control the inverter using the control parameters.
