Abstract: An electric axle drive train having an electric machine having a rotor which is mounted rotatably relative to a stator and can be supplied with current by a control unit; a gear assembly which is coupled to the rotor; and a first rotatably mounted output shaft which is operatively connected to the gear assembly in a torque-transmitting manner. An actuatable rotation blocking device is positioned in the torque flow between the rotor and the first output shaft in such a way that a rotation of the shafts lying in the torque flux can be blocked, and furthermore at least one rotational angle sensor is positioned between the rotor and the rotation blocking device in such a way that it provides a signal, that represents the rotational angle position, to a shaft lying between the rotor and the rotation blocking device.

Abstract: A plug holding device for holding a connection plug of an electrical plug connection on a housing section of a housing of an axle device includes a holder configured to hold the plug holding device on the housing section of the housing of the axle device and to hold the connection plug of the electrical plug connection. The plug holding device further includes a positioner configured to position the connection plug of the electrical plug connection relative to the plug holding device. The holder includes a feed-through configured to receive a male section of the connection plug of the electrical plug connection.

Abstract: An oil drip pan for rotationally fixed placement onto a shaft, which is rotatable about an axis, includes a pan bottom which extends in an axial direction, is closed on the circumference, and from which two pan walls extend radially inwards towards the axis. A channel is defined by the pan bottom and the two pan walls. The channel is arranged to, when the shaft rotates, receive hydraulic fluid. At least portions of the pan bottom have surface structures extending in the axial direction and protruding inwards in a radial direction out of the pan bottom. The surface structures are configured such that the hydraulic fluid flows over the surface structures in a circumferential direction when the shaft rotates, and solid particles from the hydraulic fluid are deposited in pan pockets defined by circumferentially adjacent surface structures.

Abstract: The disclosure relates to an electric axle drive train of a motor vehicle. The drive train includes an electric machine having a rotor which is mounted rotatably relative to a stator and can be supplied with current by a control unit, a gear assembly which is coupled to the rotor and a first rotatably mounted output shaft which is operatively connected to the gear assembly in a torque-transmitting manner. The output shaft is connected in a torque-transmitting manner to a vehicle wheel of the motor vehicle. An actuatable rotation blocking device is positioned between the rotor and the vehicle wheel in such a way that a rotation of shafts lying in a torque flux can be blocked. At least one rotational angle sensor is positioned between the rotor and the rotation blocking device in such a way that it provides a signal, that represents a rotational angle position, to a shaft lying in said torque flux.

Abstract: An electric machine for use within the powertrain of a hybrid or fully electric motor vehicle including a stator and a rotor which is separated from the stator by an air gap, said stator and rotor being received in an engine housing. The rotor is rotatably mounted relative to the stator by means of two axially spaced rolling bearings, and at least one of the rolling bearings is axially biased by a spring element which is supported against the motor housing in the axial direction and lies against the rolling bearing. The biased rolling bearing has an inner ring and an outer ring, between which a plurality of rolling bodies are received in a rollable manner, the inner ring is rotationally fixed to the rotor via a first bearing seat, and the outer ring is rotationally fixed to the engine housing via a second bearing seat. The spring element is arranged on the first bearing seat and/or second bearing seat so as to be secured in the axial direction in a form-fitting manner.

Abstract: An electrical machine, in particular an axial flux motor, with a rotor, mounted rotatably about a machine axis, and with a stator. The stator has a sintered support structure and an insert connected thereto, which forms at least partially a pole shoe, and which comprises a lamination stack.

Abstract: A drive unit includes a housing having first and second chambers. An electromotive drive is disposed in the first chamber and including a hollow rotor shaft. A transmission is disposed in the second chamber and includes an output shaft extending through the rotor shaft such that a gap is formed. The transmission further includes a gearing arrangement that operably couples the output shaft to the rotor shaft and reduces a speed ratio between the rotor shaft and the output shaft so that the output shaft rotates slower than the rotor shaft when operating. The gearing arrangement includes a first element fixed to the rotor shaft and a second element that rotates slower than the first element when operating. An annular clearance is defined between the first and second elements. An annular seal has a first portion engaging with the first element and a second portion engaging with the second element.
