DEFINITION

Classification: 475/194

Torque responsive means to increase contact pressure:

(under subclass 193) Subject matter including means for sensing resistance to movement or change in resistance to movement of a load device* or of a member in a drive train*;

and, in response to such sensed resistance or change of resistance to movement, said means acts to increase pressure of frictional contact between said planet pinion* and a mating gear.
