Abstract:
1. An electro-mechanical brake comprising: a driving unit that generates a rotational force in accordance with a selective application of a brake pedal; a differential gear unit connected to the driving unit, the differential gear unit comprising a first shaft and a second shaft that are disposed in a straight line to serve as a rotational shaft and are rotated in the same direction by the rotational force provided by the driving unit; an external braking unit comprising an upper rack and an outer caliper, the upper rack connected to the first shaft of the differential gear unit to provide a braking power to an outer surface of a disc by moving back and forth the outer caliper according to the rotation of the first shaft of the differential gear unit; and an internal braking unit comprising a lower rack and an inner caliper, the lower rack connected to the second shaft of the differential gear unit to provide a braking power to an inner surface of the disc by moving back and forth the inner caliper according to the rotation of the second shaft of the differential gear unit, wherein when the driving unit is driven, the rotational force of the driving unit is transmitted to the differential gear unit, and the transmitted rotational force is simultaneously applied to the external braking unit and the internal braking unit that are connected to the differential gear unit to provide the braking powers to the disc by simultaneously moving back and force the outer and inner calipers according to the rotation of the differential gear unit and wherein the external braking unit further comprises:
