Controllable coupling assembly

摘要

A controllable coupling assembly includes first, second and third coupling members supported for rotation relative to one another about a common rotational axis. A face of the first coupling member has pockets spaced about the axis. A face of the second coupling member has locking formations that are engaged by struts upon projecting outwardly from the 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. A face of the third coupling member has pockets spaced about the axis. A different face of the second coupling member has locking formations that are engaged by struts from the third member to prevent relative rotation of the second and third coupling members with respect to each other in at least one direction about the axis.

1. A controllable coupling assembly comprising:
first, second and third coupling members, each of the coupling members being supported for rotation relative to each of the other coupling members about a common rotational axis, the first coupling member having a coupling first face oriented to face axially in a first direction along the rotational axis, the third coupling member having a coupling third face oriented to face axially in a second direction along the rotational axis, the second coupling member having a coupling second face opposed to the first face and oriented to face axially in the second direction along the rotational axis and the second coupling member having a coupling fourth face opposed to the third face and oriented to face axially in the first direction along the rotational axis; the first face having a first set of pockets spaced about the rotational axis, each pocket of the first set having a strut of a first set of struts received thereby; the second face having 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 having a second set of pockets spaced about the rotational axis, each pocket of the second set having a strut of a second set of struts received thereby; and the fourth face having 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.
