A torque transmission device for a powertrain of a motor vehicle has an input area and an output area. A torque path runs from the input area to the output area. A torsional vibration damping unit is positioned first, followed by a gear unit, along the torque path between the input area and the output area. The torsional vibration damping unit provides a first spatial area and an adjoining second spatial area along the torque path, and the gear unit provides an adjoining third spatial area.

Torque-transmission device

A torsional vibration damper, especially a dual-mass flywheel, has a primary side and a secondary side, which is free to rotate around an axis of rotation relative to the primary side. Starting from a rotation in a direction of rotation around a forward base angle (&#x3b3;), a forward base spring arrangement exerts a forward base restoring force on the secondary side. Starting from rotation around a forward auxiliary angle (&#x3b4;), which is greater than the forward base angle (&#x3b3;), a forward auxiliary spring arrangement exerts an additional forward auxiliary restoring force. Upon rotation around a forward limit angle (&#x3b5;), both spring arrangements come to a stop together.

Torsional vibration damper, especially a dual-mass flywheel

A drive system having an electric machine, by which a drive shaft of a drive assembly is capable of being driven in rotation and/or electric energy is capable of being recovered during the rotation of the drive shaft. The electric machine has a stator arrangement and a rotor arrangement connected or connectable to the drive shaft for joint rotation about an axis of rotation. A positive guidance arrangement is provided via which the rotor arrangement and the stator arrangement are guided relative to one another when a relative axial movement is carried out for assembling or dismantling the electric machine.

Drive system

A drive system for a motor vehicle includes an electric machine arranged for driving a driveshaft of a drive unit and obtaining electrical energy during rotation of the driveshaft. The electric machine has a stator arrangement and a rotor arrangement which is connectable to the driveshaft for common rotation. The rotor arrangement is connectable to the driveshaft via an elastic connecting arrangement.
