Torque Limiting Clutches For Power Transfer Units

A transfer case comprising:

• an input shaft;
• a first output shaft in a driven engagement with said input shaft;
• a second output shaft in a driven engagement with said first output shaft;
• and
• a torque limiting mechanism drivingly disposed between said first output shaft and said second output shaft and including a coupling member and a biasing member, at least one of a driving member and a driven member having a recess therein configured to engage said coupling member, said at least one of said driving member and said driven member having said coupling member urged into an engagement therewith by said biasing member.
