  • Alignment features in electromagnetic retarder and assembly comprising such a retarder
    Patent number: 12142995
    Abstract: An assembly comprising a rotational driving mechanism of a drive shaft, and an electromagnetic retarder capable of slowing down the rotation of the drive shaft. The driving mechanism has a housing and a drive shaft extending along an axial direction. The electromagnetic retarder has a stator support fixed to the housing that has at least one relief extending along the axial direction, and in that the housing comprises at least one complementary relief cooperating with at least part of the relief of the stator support to fix the position of the stator support in relation to the housing along at least one direction contained in a plane perpendicular to the axial direction.
    Type: Grant

  • Interchangeable stator with asymmetric pole shoe for electromagnetic retarder
    Patent number: 9083228
    Abstract: A stator (1?) for electromagnetic retarders intended for vehicle gearbox and axle installations, includes at least one electromagnetic coils (2) assembly, two identical annular radial flanges (5?, 5?), and an asymmetrical pole shoe (6) on each radial transverse face of the two ends of each of the electromagnetic coils, and attached by a central axial screw (7), perforated attachment studs that are symmetrical relative to a median plane (M) between and parallel to the transverse faces, attached to the electromagnetic coil (2) support (5?, 5?) in order to attach the stator (1?) beside one or the other of the transverse faces to a stator support of the vehicle, using fasteners.
