摘要:
The invention concerns 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 means (28) controlled to be selectively interlocked with the gearbox output shaft (12), said means (28) being controlled by mechanical means (30, 32, 34) common to all the loose pinions (26) of the different gear ratios. The invention enables in particular gear ratio shift with uninterrupted torque transmission to the gearbox output shaft (12).
