Abstract
An electric machine with a stator and a rotor arranged in the drive train of a drive unit is disclosed. A vibration insulation device is incorporated in the rotor of the electric machine. The electric machine can function as a starter/generator, a generator vehicle brake, an auxiliary drive and/or an active vibration damper.
Claims19
An apparatus comprising:
- a drive train having a drive side, a driven side, and a torque path by which torque is transferred from the drive side to the driven side;
- a stator;
- a rotor disposed adjacent the stator within the torque path of the drive train, the rotor defining a substantially hollow interior;
- and
- a vibration insulation device disposed at least in part within the hollow interior of the rotor and within the torque path of the drive train, the vibration insulation device including a first part connected to the drive side of the drive train, a second part connected to the driven side of the drive train, and a torsionally elastic coupling device coupling the first and second parts, such that the first part is radially disposed relative to the second part.
