Abstract

Viene descritto un dispositivo di comando atto ad effettuare la selezione delle marce in un cambio di velocità di un veicolo; la sua principale caratteristica consiste nel fatto che sulla barra selettrice portante angolarmente ed assialmente solidale il nasello di comando delle forcelle di innesto marcia è supportato folle contro l'azione di mezzi elastici un elemento assialmente fisso rispetto ad una carcassa del cambio rispetto alla quale la barra selettrice è assialmente mobile, tale elemento essendo trascinato in rotazione insieme alla barra selettrice dal nasello di comando e portando radialmente di sbalzo una coppia di naselli di bloccaggio disposti angolarmente sfalsati rispetto al nasello di comando e simili a questo, atti a selettivamente impegnare le forcelle di innesto marcia immediatamente adiacenti da parti opposte a quella impegnata dal nasello di comando.
