Abstract:
1. A clutch assembly comprising: a driving member; a driven member; and a transfer member axially movable between a retracted position and an extended position; the transfer member being coupled to the driving member with one or more links when the transfer member is in its retracted position so that the transfer member is driven to rotate with the driving member as a result of force transmitted through the one or more links; the transfer member configured to engage with a driving lug of the driving member when the transfer member is in its extended position so that the transfer member is driven to rotate with the driving member as a result of force transmitted through the driving lug; the transfer member being configured to engage with a driven lug of the driven member to rotate the driven member when the transfer member is in its extended position; the transfer member being disengaged from the driven member when the transfer member is in its retracted position; wherein the one or more links are attached to the driving member at one or more first pivot points; wherein the one or more links are attached to the transfer member at one or more second pivot points; and wherein a circumferential displacement of the one or more first pivot points relative to the one or more second pivot points results in change of axial distance between the first and second pivot points and a corresponding axial displacement of the transfer member relative to the driving member.
