Controllable coupling assembly and coupling member for use in the assembly

A controllable coupling assembly having multiple operating modes, the assembly comprising:

• first and second coupling members supported for rotation relative to one another about a common rotational axis in a first operating mode, the first coupling member including:
• a first coupling face oriented to face axially along the axis and having a set of locking formations, each of the set of locking formations defining a first load-bearing surface adapted for abutting engagement with a load-bearing surface of a first locking element in a second operating mode;
• and
• a second coupling face oriented to face radially with respect to the axis and having a reverse pocket receiving a reverse locking element and defining a second load-bearing surface adapted for abutting engagement with a load-bearing surface of the reverse locking element in a third operating mode.

A controllable coupling assembly for use in an electronic vehicular transmission, the assembly comprising:

• first and second coupling members supported for relative rotation about a rotational axis, the first coupling member having a first coupling face oriented to face radially with respect to the axis and the second coupling member having a second coupling face oriented to face radially with respect to the axis and having a set of locking formations, each of the locking formations defining a load-bearing second surface, the first coupling face being in close-spaced opposition to the second coupling face and having a reverse pocket defining a load-bearing first surface, a reverse locking element received within the reverse pocket in an uncoupling position and movable outwardly from the reverse pocket to a coupling position to couple the first and second coupling members together, the coupling position being characterized by abutting engagement of the reverse locking element with the load-bearing first and second surfaces;
• and
• an electromechanical component supported by the first coupling member and including:
• a housing part having a closed axial end;
• an electromagnetic source including at least one excitation coil at least partially surrounded by the housing part;
• and
• a reciprocating member arranged concentrically relative to the at least one excitation coil and being axially movable to move the reverse locking element to either the coupling position or the uncoupling position when the at least one excitation coil is supplied with current.
