The invention relates to a rotor assembly which is mounted such as to rotate around an axis of rotation (X-X') and which comprises two magnet wheels with claws (). The aforementioned magnet wheels are separated by an axial space and are disposed opposite one another. Moreover, each wheel () comprises an end shield () which is essentially perpendicular to the aforementioned axis (X-X&#x2032;), and claws () extended axially from said end shield () towards the other wheel (). The claws () of one wheel () are solidly connected to the end shield () by respective bases () which are separated from one another by peripheral spaces (). The inventive assembly comprises at least one fan () which is positioned on an axial face of the end shield (11) of one of the wheels () opposite the other wheel (), such that the fan () axially seals at least part of one of the peripheral spaces ().

The covering element has a visible face and an invisible face opposite the visible face. It includes a weakening line which is formed on the invisible face and defines a gate zone which is to open under the pressure of the deployment of the airbag when the motor vehicle is subjected to an impact. The weakening line includes a groove which has a given total length and is delimited by a bottom and at least one transverse rib which projects relative to the bottom and closes the groove at least partially. The covering element has a thickness of material between the visible face and the bottom which is between predetermined minimum and maximum limits over most of the total length of the groove. The groove includes at least one zone of lesser strength in which the thickness of material between the visible face and the bottom is less than the minimum limit.

A method for managing a torque applied to an output shaft of a combustion engine, the combustion engine including combustion chambers, in each of which there is mounted a piston connected to the output shaft in order to apply a torque to it, the output shaft being connected to a rotary machine associated with a management member. The method involves detecting conditions of deactivation of one combustion chamber and controlling the rotary machine so as to apply to the output shaft, prior to the deactivation of one combustion chamber, a compensating torque which tends to cause a resultant torque applied to the output shaft to tend towards a deactivation torque applied by the combustion engine to the output shaft after deactivation of the combustion chamber.
