ABSTRACT:
An infinitely variable transmission comprising a pair of rotary, generally conical, torque-transmitting members (20, 22), each being mounted for rotation on its geometric axis (82, 84), the angularity of the axes, one with respect to the other, being variable, the outer surfaces of each member having torque-transmitting needles (86, 88) extending outwardly from the generally conical surface, the needles of member meshing with the needles of its companion member, the needles being capable of flexing whereby torque may be transmitted through the rotary member without frictional sliding motion at the area of meshing engagement of the needles, the angularity of one member with respect to the other permitting a wide torque-transmitting ration range.
