Abstract

Electrically conductive element for a rotating electrical machine.Electrically conductive element (20) for an electrical machine of a vehicle, the electrically conductive element (20) being intended to be arranged between two members (16, 17) rotating relative to each other, at least one of the members (16, 17) of the machine (10) rotating about an axis of rotation (X), the electrically conductive element (20) being characterized in that it comprises a central electrical contact zone (22) of spherical shape for establishing electrical contact between said members (16, 17), and a peripheral edge (24) intended to hold the electrically conductive element (20) in position, said central contact zone (22) being connected to the peripheral edge (24) by means of an elastic arm (26) configured to allow elastic deformation of the electrically conductive element (20) and a displacement parallel to the axis of rotation of the central contact zone (22) relative to the peripheral edge (24).

Claims

preceding, characterized in that it comprises a locking means configured to prevent rotation of the conductive electrical element (20) when the latter is mounted in the rotating electrical machine (10).

7. Electrically conductive element according to one of the preceding claims, characterized in that it further comprises a bottom wall (28) configured to be mounted on the peripheral edge (24).

8. Rotating electrical machine (10), characterized in that it comprises an electrically conductive element (20) according to one of the preceding claims.

9. Rotating electrical machine (10) according to the preceding claim, characterized in that the electrically conductive element (20) is arranged between an electrical grounding contactor (17) of the rotating electrical machine (10) and a rotor shaft of the rotating electrical machine (10), so that the central electrical contact zone (22) establishes electrical contact between said contactor (17) and the rotor shaft.

10. Motor vehicle, characterized in that it is equipped with a rotating electrical machine (10) according to the preceding claim. [Fig. 1]
