ABSTRACT:
A clutch or brake assembly is disclosed for controlling the relative rotation between two rotary members. Wedge means are carried between a pair of facing cam plate surfaces by an axial core member. The wedge means are axially movable with respect to the core member but prevented from rotating about the core member. The wedge means extend beyond the ends of the core member but, when the cam surfaces are aligned, are spaced therefrom to permit relative rotation between cam surfaces and the core member. When the cam plates are moved out of alignment, the distance between them is less than the axial length of the wedge means, causing the wedge means to wedge tightly between the cam plates. Because the wedge means is prevented from rotating relative to the core member, when it is wedged or locked between the cam plates they are also prevented from rotating relative to the core member.
