  • CLUTCH STRUT, TORQUE LOCKING MECHANISM, AND CLUTCH ASSEMBLY
    Publication number: 20230323922
    Abstract: A clutch assembly includes a pocket plate, and a teeter-totter strut retained in a pocket plate pocket and pivotable to engaged and disengaged positions. A strut center of mass is configured so that when a shock load force acts on the strut, the strut is prevented from moving into the engaged position. A torque locking mechanism includes a strut housing having a strut pocket, a strut having ears, and a cover. The strut has a center of mass between the ears and a portion of the pocket. A clutch strut includes ears extending transversely from a body. A first portion of the body between the ears and an abutment surface has a first length and width, and a second portion of the body between the ears and a load bearing surface has a second length longer than the first length and a second width narrower than the first width.
