Abstract
An electromagnetic retarder (1) for a vehicle includes a disc (20), a first rotor (5) and a second rotor (6), the disc being arranged to couple the first rotor and the second rotor to a transmission shaft of a vehicle. In order to facilitate fitting of this transmission shaft on the electromagnetic retarder, the invention provides for positioning the disc on one of the two rotors in such a way that the disc is placed in a position offset longitudinally, with respect to an axis (21) of the retarder, towards one of the two rotors. The disc includes fastening means for fastening the disc on the corresponding rotor, which fastening means (22) are such that they are positioned between curved arms (9, 10) of the rotor.
Claims8
An electromagnetic retarder (1) for a vehicle, having at least one inductor (2), being a stator and adapted to carry at least one electromagnetic winding (3),
- a first rotor (5), being an armature, and a second rotor (6), being an armature, the said first rotor and second rotor being coupled together by means of a central fastening ring (19), each rotor being situated on either side of a plane defined by the stator (2), and
- at least one disc (20) adapted to connect the first rotor and the second rotor to a transmission shaft of the vehicle,
- characterised in that the disc is fixed on one of the two rotors in such a way that it is positioned in longitudinal offset relationship, with respect to an axis (21) of the retarder, towards that rotor.
