Abstract

An automated gear drive, comprising two main gearshafts (18, 20) bearing drive pinions (22, 24) and linked each by a clutch (E1, E2) to a clutch shaft (10), a gearbox output shaft (12) bearing driven pinions (26) each of which is associated with one-way locking device (28) controlled to be selectively interlocked with the gearbox output shaft (12), the one-way locking device (28) being controlled by mechanical device (30, 32, 34) common to all the loose pinions (26) of the different gear ratios. The automated gear drive enables in particular gear ratio shift with uninterrupted torque transmission to the gearbox output shaft (12).
