ABSTRACT:
The invention relates to a vehicle transmission including an eddy current retarder, the stator of which is fastened to the housing of a gearbox by fastener members and the rotor of which is connected to the gearbox outlet shaft. According to the invention, the fastener members include at least two rigid parts, one fastened to the stator and the other to the rotor, each of the two parts including a bearing surface which corresponds to at least part of a surface of revolution centered on the gearbox outlet shaft, the two bearing surfaces being separated by a layer of an elastomeric material which is bonded to the two bearing surfaces and which allows a certain relative angular displacement of the two rigid parts, the two rigid parts being unmovable relative to one another in a direction parallel to the width of the air gap which separates the rotor and the stator.
