ABSTRACT:
G,1 A torque converter for inclusion between a driving shaft and a driven shaft has a driving gear rotatable about a primary axis and in mesh with planetary gears rotatable about second axes parallel to the primary axis. The planetary gears are coupled to eccentric weights also rotatable about the secondary axes in a predetermined phase relationship. The planetary gears and weights are coupled to a driven gear with which there may be selectively meshed either one of a pair of pinions. Each pinion is provided with a unidirectional clutch engagable with a torque shaft having limited rotation and essentially fixed. The clutches work in opposite directions. Preferably, both the driving shaft and the driven shaft, as well as the torque shaft, are provided with torque cushions to smooth out variations in torque. Special inertia relationships are maintained.
