ABSTRACT:
This invention concerns a power transmission gearing having friction devices i.e. clutches and/or brakes for holding and freeing parts of the gearing for changing the driving ratio, said devices having axially engageable friction surfaces which are urged in opposite directions by resilient means so that some engaging load can be applied or released and co-operating surfaces having a cam action are connected with the respective friction surfaces and so arranged that the torque load transmitted by the friction surfaces acts to produce an additional load in the axial direction which presses the friction surfaces together.
