PURPOSE: A clutch-brake assembly is provided to transmit power from a drive member to a slave member to rotate a shaft and transmit power from a fixed member or frame to suppress rotation of the shaft. CONSTITUTION: A clutch-brake assembly is utilized to rotate a shaft and transmit force to retain a shaft against rotation. The clutch-brake assembly includes a wedge member, which is disposed in a central opening in a base member. An actuator(298) is operable to move the wedge member relative to the base member. A seal assembly(244) is disposed in the central opening in the base member. A plurality of force transmission members(552) transmit force when a friction surface is pressed against a clutch surface and when a friction surface is pressed against a brake surface. Each of the force transmission members extends around and at least partially encloses a spring(138). Guide members are advantageously utilized to position components of the clutch-brake assembly relative to each other during formation of the clutch-brake assembly. |
