Abstract

The reverse drive gear wheel is mounted to be fixed in translation on its selector shaft (26). The gear ratio selector and engagement control element (20) comprises a peg (23) engaging directly with a notched yoke (31) fixed to the selector shaft (26). The peg is so designed that a reverse drive ratio engagement angular movement is roughly double that of another peg (22) used to operate the forward drive gear selector shafts.
