Abstract

Cambio di velocità ad ingranaggi sempre in presa per autoveicoli, in cui l'ingranaggio ozioso della retromarcia (14) è costantemente solidale in rotazione con l'albero secondario (2) attraverso l'una o l'altra di due corone dentate (12, 13) portate da un manicotto scorrevole di innesto (10) associato ad una coppia di ingranaggi (8, 9) dell'albero secondario (2).(Figura 1).
