CONTROLLABLE COUPLING ASSEMBLY

摘要

A controllable coupling assembly is provided. The assembly includes first, second and third coupling members supported for rotation relative to one another about a common rotational axis. The first coupling member has a coupling first face oriented to face axially in a first direction along the axis. The third coupling member has a coupling third face oriented to face axially in a second direction along the axis. The second coupling member has a coupling second face opposed to the first face and oriented to face axially in the second direction along the axis and the second coupling member has a coupling fourth face opposed to the third face and oriented to face axially in the first direction along the axis. The first face has a first set of pockets spaced about the axis. Each pocket of the first set has a strut of a first set of struts received thereby. The second face has a first set of locking formations that are engaged by the struts upon projecting outwardly from the first set of pockets to prevent relative rotation of the first and second coupling members with respect to each other in at least one direction about the axis. The third face has a second set of pockets spaced about the axis. Each pocket of the second set has a strut of a second set of struts received thereby. The fourth face has a second set of locking formations that are engaged by the second set of struts upon projecting outwardly from the second set of pockets to prevent relative rotation of the second and third coupling members with respect to each other in at least one direction about the axis.
