ABSTRACT:
According to the present invention, a one-way, bi-directional clutch, includes an outer casing, an input shaft, an output shaft and a brake assembly. The input shaft includes a release cam portion and the output shaft includes a locking cam portion. The brake assembly includes a release cam portion that is complementary to the release cam portion of the input shaft, a locking cam portion that is complementary to the locking cam portion of the output shaft, a biasing element and at least one brake pad. The complementary release cam portion of the input shaft and brake assembly are operable to move the brake assembly to a release position when the sufficient torque is applied to the input shaft. The complementary locking cam portions of the output shaft and the brake assembly are operable to move the one or more brake pads to the brake position when the sufficient torque applied to the output shaft.
