DISPOSITIF DE VERROUILLAGE DE COMBINAISONS DE RAPPORTS D'ENGRENAGE D'UNE TRANSMISSION DE VEHICULE, ET ENSEMBLE COMPRENANT CETTE TRANSMISSION ET CE DISPOSITIF

摘要

A transmission interlock for use in a motor vehicle transmission having at least two gear ratio selection means in tandem within a common housing. The transmission interlock includes an auxiliary shift rail parallel to and spaced from two operative shift rails which it interlocks. The auxiliary shift rail is linked to one of the two shift rails and translates positively therewith. An interlock member transversely disposed between the auxiliary shift rail and the second of the two shift rails interacts with slots or blind apertures in the shift rails to prevent selection of certain combinations of shift rail positions corresponding to prohibited gear ratio combinations.
