ABSTRACT:
The reversing mechanism (10, 200) for the motor drive comprises an electric motor (39) which drives a shaft (41) having mounted thereon a first gear (44) and a shifting mechanism in the form of a flywheel (100). The first gear (44) engages a second gear (37) which engages a third gear (38), the second (37) and third (38) gears being mounted upon a carrier mechanism (12) and each engageable with a driven gear (31). The carrier mechanism (12) is engaged by a cam mechanism (60). The shifting mechanism (100) engages an axial mechanism (70) which when displaced by the shifting mechanism (100) causes the cam mechanism (60) to rotate. Rotation of the cam mechanism (60) causes displacement of the carrier mechanism (12) so that one of said second (37) and third (38) gears disengages the driven gear (31) and the other of the second (37) and third (38) gears engages the driven gear (31) in order to effect a reverse direction of rotation of the driven gear (31) when the motor (39) recommences operation. The reversing mechanism (10, 200) may be utilized in an electrically actuated parking brake system.
