Compact torque limiting clutch

A torque limiting clutch, comprising:

• an input flange;
• an output hub;
• a pressure plate received upon said output hub;
• a first friction disc interposed between said pressure plate and said input flange;
• a keeper plate received by said hub, said keeper plate fixedly securing said first friction disc to said output hub;
• spring biasing means interposed between said input flange and said pressure plate for urging said pressure plate toward said input flange;
• and
• first and second cup-shaped annular shields positioned adjacent each other and between said pressure plate and first friction disc, said first cup-shaped annular shield having side edges extending over said input flange and said second cup-shaped annular shield having side edges extending over said pressure plate.
