<p>The electrically actuated cable mechanism (10) comprises a housing (12) disposed about the cable (15) and having a movable conduit (20) extending from one end and a stationary conduit (30) extending from the other end, each conduit (20, 30) being disposed about the cable (15). Located between the conduits (20, 30) and engaging the movable conduit (20) is a hollow screw (25) which is disposed about the cable (15). The hollow screw (25) has a non-circular end (27) received in a complementary shaped opening (18) of the housing (12) in order to prevent rotation of the hollow screw (25). An electric motor (40) drives rotatably a nut (35) which engages threads of the screw (25) so that rotation of the nut (35) by the motor (40) causes axial displacement of the hollow screw (25) and a corresponding displacement of the movable conduit (20) relative to the stationary conduit (30) and housing (12), which, by reaction, causes the cable (15) to be displaced. The cable (15) may be attached to parking brake mechanisms of a vehicle.</p> |
