<p>A differential drive assembly 10 for a motorised vehicle, comprises a solid drive shaft 14 connectable to a driven wheel of the vehicle, a hollow drive shaft 16 within which the drive shaft 14 is rotatably received and which is connected to a second drive wheel of the vehicle; and a differential 18 which is coupled to the drive shafts. The drive shafts 14, 16 have drive sprockets 64 and 66, respectively, fixed thereto. The differential includes a sprocket 58 which is driven by a drive chain coupled to the motor of the vehicle; and a planetary socket arrangement including a planetary shaft 76 which is fixed relative to the sprocket 58 and pair of planetary sprockets 78.1 and 78.2 are coupled by means of chains to the drive sprockets 64, 66 in an arrangement which permits the drive shafts to rotate at different speeds relative to one another.</p> |
