An electric drive for may have at least one electric machine in a housing with a rotor shaft forming the drive shaft, which can be coupled to an intermediate shaft via at least one spur gear, wherein the intermediate shaft is coupled to an output differential for driving output shafts, wherein there is at least one oil pump for pumping transmission fluid, wherein a pump shaft in the oil pump can be driven in the same direction of rotation via a first drive path, which has at least one first freewheel, and via a second drive path, which has at least one second freewheel and at least one differential, and wherein at least the first freewheel and the second freewheel, as well as the differential, are located radially inside the hollow intermediate shaft.

Electric drive for a vehicle

A drivetrain module for a motor vehicle having a clutch with an input area and an output area. A mutual rotational driving of the input area and output area is influenceable by the action of the clutch. The clutch has a clutch housing with a clutch space formed therein. The input area and the output area are arranged at least partially in the clutch space. The clutch space is filled and is closed to be tight against fluid relative to a surrounding area of the clutch space. The clutch has a pressure compensation device for compensation of a pressure difference acting between the clutch space and the surrounding area.

An axially actuatable positive engagement clutch which includes an input shaft with an input toothing and an output shaft with an output toothing. An axially displaceable connection element can occupy a meshing position which is located in an actuation path (s) between the open position and the closed position and in which the driving toothing engages with the input toothing or the output toothing for the first time during the transition from the open position into the closed position. An actuation device is configured to displace the connection element from the closed position to the open position, and an elastic return element which applies a restoring force to the connection element in direction of the closed position. The return element has a force/deflection characteristic with a local force maximum (F1) which coincides in the actuation path (s) at least approximately with the meshing position of the connection element.

Positively locking clutch having a restoring element

An assembly for a motor vehicle has an electric machine and a clutch actuating device. The electric machine has a machine housing, a rotor and a stator. The stator includes a stator carrier with a fluid cooling jacket constructed substantially as an annular space, a fluid inlet, and a fluid outlet spaced apart from the fluid inlet. The stator encloses a central receiving space in which a pressure medium cylinder of the clutch actuating device is arranged. The pressure medium cylinder has a pressure medium inlet arranged inside the axial extension of the stator carrier and can be brought into fluidic connection with, or is fluidically connected with, a pressure source via a pressure medium channel extending from the machine housing. The pressure medium channel is constructed at least partially in a wall portion of the stator carrier adjoining the central receiving space.

Constructional unit includes an electric machine with a stator and with a rotatable rotor, a rotatable output element operatively communicates with the rotor to transmit torque, and an offset arrangement. The offset arrangement is arranged between the rotor and the output element, and the transmission of torque is enabled in case of an axial offset and/or an angular offset between a rotational axis of the rotor and a rotational axis of the output element.

A drive unit for a motor vehicle includes an electric machine which has a stator, a rotor and clutch for producing a rotary driving connection of the rotor to a drive element. The clutch has a release member which is axially displaceable by an actuating device arranged at least partially in a receiving space surrounded by the stator. The actuating device has an electric actuator drive motor and an actuator drive shaft directed transverse to the axis of rotation of the drive unit. The actuator drive shaft is operatively connected to a release arrangement which includes a rotatable input element which is fixed axially relative to the release member and an output element which is axially displaceable relative to the input element and which is operatively connected to the release member.

A torsional vibration damper arrangement including a torsional vibration damper with a primary side and a secondary side rotatable with respect to the primary side around an axis of rotation against the action of a damper spring arrangement. One side of the primary side and secondary side includes two cover disk elements and a central disk element arranged between the cover disk elements. The cover disk elements are connected to one another by first connection elements radially inside the damper spring arrangement so as to be fixed axially and so as to transmit torque. The cover disk elements are connected to one another by second connection elements in such a way that they are prevented from moving axially away from one another. No torque can be transmitted between the cover disk elements by the second connection elements.

Torsional vibration damping arrangement, particularly for the power train of a vehicle

A drive unit for a motor vehicle having an electric machine including a rotor mounted so as to be rotatable around an axis A and coupleable, with a driveshaft acting on the vehicle wheels, and a stator having an electric winding whose terminations are connected to a power source by a connection device arranged at a housing opening of the drive unit and guided through this opening. A housing element encloses the rotor and the stator on the radially outer side. To arrange the connection device such that the installation space is optimized, the winding terminations are connected to first contact elements arranged fixed in position at the stator constructed as axial connectors with respect to the electric machine, and constitute stator contacts. These first contact elements are connected to second contact elements constructed to correspond to the first contact elements arranged at a wall area of the drive unit, and constitute wall contacts. The wall contacts are electrically connected to the connection device or form this connection device.
