Torque transmitting device with a lever apply spring

A torque transmitting assembly comprising:

• a housing having a splined periphery;
• an annular piston slidably disposed in said housing and cooperating therewith to form a fluid chamber;
• a plurality of first friction plates drivingly connected with said splined periphery;
• a plurality of second friction plates alternately spaced with said first friction plates, said first and second friction plates being in radial alignment with said piston;
• a lever spring having a base portion disposed adjacent said piston, an apply portion disposed adjacent one of said friction plates, one of said base portion and said apply portion comprised of finger members each extending through respective slots formed in said housing, said lever spring being retained in said slots by a reaction member secured to said housing and providing a fulcrum for said lever spring;
• and
• means drivingly connected with said second friction plates, said fluid chamber being pressurized to urge said piston toward an engaged position to act on said lever spring to enforce frictional engagement between said first and second friction plates to establish a torque transmitting relation between said housing and said means drivingly connected with said second friction plates.
