发明名称 Ventilation Assembly
摘要 A ventilation assembly for a vehicle has a stationary load-bearing structure, including an outer frame and an inner annular support element connected to the frame by means of a plurality of spokes. The support element has a cylindrical outer skirt. An electric motor has an inner stator fixed to the annular support element and an outer rotor which extends around the stator. A fan fixed to the rotor, has a hollow hub from which a plurality of blades extend. The hub extends around the rotor and has a front wall and an annular, side wall which surrounds the motor. The side wall of the hub of the fan partially penetrates inside the skirt of the annular support element in the axial direction.
