Abstract
A ventilation unit for motor vehicles comprises a tubular element (5) fitted, through an opening (4) in the chassis (1) of the motor vehicle, and a hub (8), coaxial with the tubular element (5), which mounts an electric motor (10) for driving an impeller (12) fitted with blades (15); the motor and impeller are supported by connecting means (7) which are provided between the tubular element (5) and the hub (8) and which define a grille (20) for protecting the opening (4); these connecting means are suitably shaped to define means for regulating the air flow generated by the impeller (12), in such a way as to increase efficiency and reduce noise; the unit (2) also comprises a cover (21) for protecting the motor (10), fitted with means (24) for quick connection/disconnection to/from the hub (8) and defining, between the hub and the motor, openings (26) to allow the passage of the air flow moved by the impeller in such a way as to cool the motor.
