  • Epicyclic friction transmission with torque-dependent pressure-exerting device
    Patent number: 4112787
    Abstract: A torque-dependent, mechanical pressure-exerting device for friction gears with a planet wheel, particularly for steplessly adjustable gears, wherein for each direction of rotation, the torque between the drive shaft and the planet wheel is resolved into an approximately radially acting contact pressure and an approximately tangentially acting circumferential force via a pair of curves (cam and counterpart), with one element of the pair of curves disposed on the drive shaft, wherein the other element of the curve pair is disposed on the shaft of the planet wheel.
    Type: Grant
