摘要 |
The invention relates to an electric retarder for vehicle whose stator (1), formed essentially by an annular flange (2) supporting a ring of substantially jointing coils (3), is mounted cantilever fashion on the casing of the rear axle or the gear box of this vehicle and whose rotor comprises two magnetic material disks enclosing the stator themselves mounted cantilever fashion, through arms (10) forming ventilation fins, on a stub shaft extending from the casing. The number of coils is increased from eight to ten or twelve, which, all other things being equal, allows the diameter (D) of the opening formed in the flange and so that of the transmission shaft to be increased. <IMAGE> |
