<p>A drive arrangement, suitably for a hybrid vehicle, comprises an electric machine 44, including a rotor 46, and a driveshaft 32 for applying torque to rotor 46 through a damping mechanism 68 arranged to damp transfer of torque between driveshaft 32 and the rotor. Damping mechanism 68 is situated within an envelope defined by the electric machine, and is preferably integrated into rotor 46, which may reduce the axial length and provide a space-efficient arrangement. Damping mechanism 68 may comprise a plurality of springs (100, Figure 5) in slots (92, Figure 5) in a main body (84, Figure 5) of a rotor hub 50. A clutch 58 may selectively couple driveshaft 32 to a torque source, such as an internal combustion engine; electric machine 44 may function as a motor providing motive power when clutch 58 is disengaged. Electric machine 44 may be a radial flux machine.</p> |
