A backstopping clutch (24) is provided having improved torque transmission. The clutch (24) includes a housing (28), an inner race (30) disposed within the housing (28) and configured for coupling to a driven member for rotation about a rotational axis (26) and an outer race (32) disposed with the housing (28) radially outwardly of the inner race (30). A plurality of torque transmission members (34) are disposed between the inner and outer races (30, 32) such that the inner race (30) is freely rotatable relative to the outer race (32) in a first rotational direction, but the torque transmission members (34) engage the inner and outer races (30, 32) and inhibit rotation of the inner race (30) relative to the outer race (32) in a second rotational direction. Friction discs (36, 38) are coupled to a radially inner surface of the housing (28) and a radially outer surface of the outer race (32) and configured to engage one another to transmit a braking torque. |
