Abstract
A locking mechanism for a driveshaft disconnect coupling includes an input jaw member defining a rotation axis, an output jaw member connectable to the input jaw member for common rotation with the input jaw member, and a cartridge assembly. The cartridge assembly is fixed to the input jaw member, includes a pin, and defines a pin movement axis. The pin is movable along the pin axis between a radially inner position and a radially outer position, the pin being disengaged from the output jaw member in the radially inner position and the pin being engaged to the output jaw member in the radially outer position.

A locking mechanism for a disconnect coupling, comprising:
- an input jaw member defining a rotation axis;
- an output jaw member connectable to the input jaw member for common rotation with the input jaw member;
- and
- a cartridge assembly with a pin fixed to the input jaw member, wherein the pin is movable along a pin axis between a radially inner position and a radially outer position,
- the pin being disengaged from the output jaw member when in the radially inner position such that the output jaw member separates from the input jaw member, and
- the pin being engaged to the output jaw member when in the radially outer position such that the output jaw member is locked to the input jaw member.
