Abstract

A vehicle transmission is constructed so as to reduce as much as possible its length due to the cantilevered mounting of an electric retarder (2, 3) with two rotor discs (9a, 9b) on the casing of the gear-box (1) of this transmission. To this end, the rotor of this retarder is supported by the periphery of a gear-box flange (14) via a tubular insert (23) having at one of its ends an internal collar (24) fixed to the periphery of the flange and at its other end, an external collar (13) surrounded by the rotor rings (10).
