Abstract

In un procedimento per il comando automatico di un cambio di velocità a ruote dentate a più vie con almeno due cambi parziali disposti parallelamente fra loro nel flusso delle forze tra un albero di entrata ed un albero di uscita con ruote folli accoppiabili di volta in volta mediante un accoppiamento a ruote dentate con il loro albero, viene generata, in presenza di veicolo fermo, una condizione di comando di avviamento in cui viene innestato sia l'accoppiamento a ruote dentate collegato con la ruota folle del gradino della retromarcia R sia l'accoppiamento a ruote dentate del gradino che forma la più bassa delle marce indipendenti dall'innesto commutabile in base al carico del cambio parziale con il gradino della retromarcia R.
