Abstract
A torque transmitter has a plurality of friction plates alternately splined at the inner and outer peripheries. The plates are urged into frictional engagement by a piston and a lever spring to accommodate torque transmission between the splined components drivingly connected with the splined peripheries. The friction plates are disposed in radial alignment with the piston and the lever spring reacts against one of the friction plates. A fulcrum for the lever spring is disposed on one of the splined components.
