ABSTRACT:
An overdrive for motor vehicles is disclosed which comprises a planetary carrier joined to an input shaft, a ring gear with internal teeth, said ring gear engaging planet pinions carried on the planet carrier and being joined to an output shaft, and a sun pinion engaging the planet pinions. A one-way clutch is disposed between the housing of the overdrive and the sun pinion and is arranged to lock the sun pinion to the housing when driving torque is transmitted from the input shaft to the output shaft. A second clutch is disposed to lock the sun pinion to the ring gear when engaged, the one-way clutch having a control which cooperates with an operator for the second clutch to suspend the blocking function of the one-way clutch before the second clutch is engaged.
