ABSTRACT:
A planetary-type overdrive for motor vehicles in which, when engaged, the sun pinion is fixed relative to the housing by means of a completely disengageable one-way clutch when torque is transmitted from the input shaft to the output shaft. Free-wheeling is achieved when torque is transmitted in the opposite direction. A brake device is coupled between the one-way clutch part joined to the sun pinion and the overdrive housing. When shifting from direct drive to overdrive, the sun pinion is braked before the one-way clutch is engaged, i.e. before its blocking function is established.
