<p>A torque transfer limiting arrangement includes a housing, an input drive shaft, an output drive shaft, and an output cam plate having a plurality of ball ramps with a plurality of balls for transmitting input torque to the output cam plate. A stator assembly is rotatably fixed relative to the housing, and includes at least one stator friction disc. A rotor assembly includes at least one rotor friction disc rotatable relative to the stator friction disc. A sensing spring permits axial displacement of the output cam plate when the input torque exceeds a predetermined maximum limit, whereupon the plurality of balls in the ball ramps cause axial displacement of the output cam to thereby drive the clutch into an engaged state causing relative rotation between the rotor and stator friction discs for isolating and frictionally dissipating the input torque.</p> |
